Mythology Gag / Fire Emblem Heroes

Go To

With Fire Emblem running for more than 30 years, and with Heroes bringing together many heroes from many games, there are bound to be a few references and nods to their home games, especially if they get skills and weapons that they did not get in their home game.

Beware of unmarked spoilers, up to and including Fire Emblem Engage. You Have Been Warned.

    open/close all folders 


    General 
  • Several of the maps from each chapter are based off of chapters from their world's game, just scaled-down. Examples of such are found below.
  • Characters returning from a game where critical quotes were available share the same quote lines.
  • Many launch characters have default skills that either reference their class skills they can potentially obtain or their personal skills they have, especially those who did not have them in their home game, such as Cecilia from The Binding Blade having Rally Resistance because of that skill being available in the Valkyrie class in Awakening and Fates, or Ogma having Noontime because a similar skill named Sol was available to the Hero class in Awakening and Fates.
  • In many of the character artworks, they wield sheathed swords alongside their main weapon. This is referencing that all of them wield swords at one point in their home game, most of them through class promotion.
  • Most Legendary and some Mythic Heroes that don't hail from Heroes itself have a finishing attack that usually relates to their critical or special attack, a class they're related to, or a finishing attack in a game they appeared in:
    • Legendary and Emblem Ike's finishing attack has him throwing up his sword in the air and catching it midair and spinning to attack, referencing both his Aether attack in the Tellius games, his Great Aether attack in Engage, and the critical attack of the Mercenary in the GBA games.
    • Legendary Ephraim's finishing attack has him spinning his lance over his head before he thrusts his lance into the enemy, referencing his critical attack as a Great Lord in The Sacred Stones.
    • Legendary Robin's finishing attack is based on the critical and skill attack of the Tactician class when they're using a tome in Awakening.
    • Legendary Lyn's finishing attack has her disappear before reappearing in the air to fire her arrow. While she does not do this in The Blazing Blade, the Assassin class in Awakening has a very similar attack as a finishing move with a bow, one she can potentially reclass into, and where she is available in Awakening through DLCnote .
    • Legendary Ryoma's finishing attack has him move back, closes his eyes and prepares his sword in front of him with both hands, then dashes and attacks his opponent with a quick upwards sword strike, referencing the finishing attack of the Swordmaster class in Fates.
    • Legendary Hector's finishing attack has him turn his back to his enemy, spin his axe overhead before slamming it down on the ground, then swing his axe as he leaps and strikes his enemy, referencing his critical attack with his Armads as a Great Lord in The Blazing Blade.
    • Legendary Lucina's finishing attack has her spin her bow in the air, follow up with a backflip and catch it, then shoot her arrow to the enemy. While it is similar to the leap attack animation of the Archer and Sniper class in Awakening, the Adventurer class in Fates has a more similar animation as its finishing attack, where Lucina is playable in that game, but cannot reclass into the Adventurer.
    • Legendary Marth's finishing attack has him point his sword up into the air, before he does five consecutive stabs towards the enemy. The sword point towards the air has appeared many times in the franchise, such as his critical hit animations in Shadow Dragon and New Mystery of the Emblem, but the rapid stabs comes from Super Smash Bros. as his Dancing Blade final down attack, his finishing attack in Fates, where he is playable in (albeit through amiibo DLC and based on his Super Smash Bros. incantation).
      • Emblem Marth's finishing and Lodestar Rush trigger attack animation removes the sword point in the sky and instead goes for a slash at the end of the attack as he jumps back compared to Legendary Marth's finishing attack, referencing his Lodestar Rush attack in Engage.
    • Legendary Young Tiki's finishing attack has her rear her head for a bit before doing her breath attack, just like her attacking animation in Shadow Dragon.
    • Legendary Eirika's finishing attack has her lift her sword towards her face, then spin it behind her before thrusting it into the enemy, referencing her critical attack as a Great Lord in The Sacred Stones.
    • Legendary Azura's finishing attack has her lean forward along with her pegasus while spinning her tome as she attacks, referencing the critical attack of the Dark Falcon class in Fates, which her Legendary variant's design is based on.
    • Legendary Roy's finishing attack has him draw his sword and bring it upwards, spins it once and swing it to his back, before attacking his opponent with an overhead swing, with the opponent also erupting in flames, referencing his regular attack with the Binding Blade equipped in The Binding Blade.
    • Legendary Alm's finishing attack has him point up his bow, spin it behind him, then fires an arrow with the bow drawn horizontally, referencing his finishing attack at close quarters with a bow as a Hero and Conqueror in Shadows of Valentia.
    • Legendary Eliwood's finishing attack has him point his sword upwards, before drawing it near him vertically, then leaps towards his enemy and does two attacks, one down and one up, referencing his critical attack with the Durandal as a Knight Lord in The Blazing Blade.
    • Legendary Julia's finishing attack references her own attacking animation in Genealogy, wherein she lifts one arm up, then extends it forward as she casts from Naga's tome, all while her robes billow in the wind.
    • Legendary Leif's finishing attack has him slowly arms his bow while he rotates it until it is horizontal while his mount leans down by retracting its front legs, with him firing when the horse reaches its lowest point. The slow draw is based on the critical attack of bow users in the Jugdral Saga, while the animation as a whole is referencing the second attack of Bow Knights in Shadows of Valentia, whereas Leif's appearance is a Master Knight, which he can promote into in Genealogy, where they can wield a large arsenal of weapons, including a bow.
    • Legendary Chrom's finishing attack may be a reference to the Sniper critical animation in Awakening. He twirls his arrow around just like a Sniper would, although he also twirls his bow around at the same time. His prowess with archery could refer to the fact that he has access to the Sniper class in Awakening.
    • Legendary Edelgard's finishing attack has her put her shield behind her as she spins her axe forward, then brings it behind her and gripping it with both hands, then finally has her do an uppercut swing, referencing how armored units perform Combat Arts with their axes in Three Houses.
    • Legendary Dimitri's finishing attack has him stab the foe three times, before he leaps up and slashes his foe with a sweep as he lands, referencing his critical attack as a Lance-wielding Infantry in Three Houses.
    • Legendary Claude’s finishing attack has him jump from his wavering and do a backflip before he fires his arrow at his foe at the apex of his jump, then he lands back on his wyvern, referencing his critical close attack as a Wyvern Master and Barbarossa in Three Houses, as well as the finishing attack of the Kinshi Knight in Fates.
    • Legendary Male and Legendary Female Byleth's finishing attack has them take out their Sublime Creator Sword and attack their foe with the sword in it's ranged form and slice their foe four times before one final slice down, referencing their Sublime Heaven Combat Art they performs in Three Houses. Ironically, they does not perform this animation when they activates their special, including their actual Sublime Heaven and Ruptured Sky, respectively, in Heroes.
    • Legendary Xander's finishing attack has him raise his axe towards his chest, before he brings it down, then as his horse leaps he swings it up and does a downswing on his foe just as the horse lands, referencing his critical attack when wielding a sword as a Paladin in Fates.
    • Formortiis's finishing attack has his eyes glow before his whole body emits a dark flame aura, before a pillar of darkness fires from underneath his foe, referencing his Demon Light weapon's animation in The Sacred Stones.
    • Legendary Elincia's finishing attack has her rear her pegasus back and raises her sword upwards, before she spins it behind her and charges with 2 slices on her foe afterwards, referencing her finishing critical attack animation as in Radiant Dawn.
  • Veyle's finishing attack has her spin around in place before posing with her arms out, referencing the tome critical hit animation of her version of the Fell Child class.

The first is based on Katarina's first attempt on Marth's life in Prologue VIII (Assassination of the Hero-King), the second is the final encounter with Clarisse in Chapter 13x (Within the White Darkness), and finally the last map is the final battle against Katarina just outside Altea castle in 16x (Reunion).

    • Gharnef's Grand Hero Battle map and the final map of Tempest Trials+: "Mirage Vortex" is based on the Finale Part 2/Chapter 23 (Dark Pontifex Lives) of Mystery of the Emblem. It also resembles Mystery of the Emblem's version of Book 1 Chapter 18 (Dark Pontifex), which has a different layout than in Shadow Dragon.
    • Book IV Chapter 9: Part 4 (Agony of Youth) features not only Triandra and Eremiya as enemies but also a Red Mage, a Bow Fighter, and an Axe Fighter, matching the classes of Eremiya's subordinates, Katarina, Clarisse, and Legion respectively.
    • Tiki and Nagi's Bound Hero Battle map is based on Chapter 24x (The Alterspire) of Shadow Dragon.

    • Medeus' Mythic Hero Battle map is based on the final part of the Final Chapter (Light and Shadow) of Mystery of the Emblem. The only green infantry tome mage in the field is a huge reference for Gharnef.
    • Matthis' Grand Hero Battle map is based on Chapter 5 of Shadow Dragon and Book 1 Chapter 4 of Mystery of the Emblem (Champions of Aurelis). Interesting, even though Matthis is recruitable in the previous chapter (Battle in the Lea) of Shadow Dragon, that chapter was cut in Mystery of the Emblem and Matthis was moved to this chapter instead.
    • The final map of Tempest Trials+: "Daughters of the Black Fang" is based on Chapter 23 (Dark Pontifex) of Shadow Dragon.
  • The division of the story mode into "books" harkens back to the original Mystery of the Emblem, where the two Marth storylines were split in the same fashion.
  • Young Marth and Phina's Rapier, Brave Marth's Genesis Falchion, Young Caeda's Feather Sword, Legendary Caeda's Faithful Loyalty, and the unique refine for Duo Winter Marth's Tanngrisnir all have the Vantage effect, referencing the Lunatic Reverse Mode in New Mystery of the Emblem, where all the enemy units attack first, regardless of who is initiating combat.
  • Catria starts with a Killer Lance, likely referencing to her joining with the same weapon (or Killing Edge in the previous games) in Shadow Dragon. Her exclusive weapon in Heroes, the Whitewing Lance, is a stronger version of the Killer Lance.
  • Est comes with the Heavy Spear, which is an anti-armor weapon just like her Armorslayer in Shadow Dragon and the Blade of Light. Her exclusive weapon in Heroes, the Whitewing Spear, is a stronger version of the Heavy Spear.
  • Jeorge wields the Parthia this game, likely referencing his high weapon rank and status as a knight of Archanea, and becoming its official wielder in Mystery of the Emblem Book 2.
    • Parthia's effect of gaining +4 Res (and on refine 30% damage reduction from tomes) is based on the +7 Res the user gains when Parthia is used as an item in most of the games it is available in.
  • Katarina betrays the heroes' side in the New Mystery-themed paralogue, just like what she did at the end of New Mystery of the Emblem's prologue.
  • Michalis moves from his placement in his Grand Hero Battle, akin to how he did so in Mystery of the Emblem as opposed to his Shadow Dragon incarnations.
    • Michalis has Iote's Shield as his A default skill, which is an item he possesses as an enemy, and drops when defeated.
  • One of Wrys' castle quotes has him boast the simplicity of his haircut and offers a similar haircut to the player. The same thing occurs in New Mystery after you recruit him.
  • Like the battles against him in New Mystery of the Emblem, Legion's Grand Hero Battle has you face multiple copies of him.
  • Caeda has a Bridal costume as an alternative unit, with Marth later getting a Groom costume. This is referencing the beginning of Mystery of the Emblem where the two of them were about to wed before conflict broke out.
  • Tiki's Breath of Fog and all her dragonstone variants has dragon effectiveness, referencing the Divinestone in her home games.
    • The exclusive refinement for Breath of Fog gives her +5 Atk/Def whenever a Sword or Breath wielder is within 2 spaces of Tiki, referencing her close relationship with Marth and Bantu in Mystery of the Emblem.
  • Linde's Aura refine gives +6 Atk to adjacent tome and staff users at the start of her turn, as well as her unique refine grants her +5 Atk/Spd if there is a Tome or Staff user within 2 spaces of her, referencing how all her closest friends and companions are Tome and Staff users, such as Merric and Nyna.
  • Merric's Excalibur refine has special cooldown acceleration, referencing the high critical rate of Excalibur in all games it is available in.
    • Like Linde, he gets +5 Atk/Spd if there is a tome or staff user within 2 spaces of him, referencing his close connections with Tome and Staff users in his home game, such as Elice(sharing close feelings with each other), Linde and Arlen (his mage friends), and Wendell(his magic teacher in Khadein).
  • Reese's Tome is a reference to Katarina's Book in New Mystery of the Emblem, and this tome being a stronger version of the Rauorowl tome might reference her holding back while she was a recruit of the 7th Platoon of Altean Knights, with her real name in her tome showing off her true strength as an assassin.
  • In the plaza, Summer Linde might challenge the summoner to a race, warning them that walking on sand is a basic skill amongst mages like herself. This is true in some main series games, where mages can walk on sandy terrain unhindered.
  • Summer Young Tiki being a fast flying dragon references the Wyvernstone in Mystery of the Emblem and its remake, where it gives a large amount of speed to the user with the downside of having a weakness to bows when equipped. Summer Tiki herself in her humanoid form having wings also references her being shown with wings in Mystery of the Emblem, but not in its remake.
  • Legendary Marth has Fire Emblem as his special, which give him 30% of his speed to his attack and himself and his allies +4 in all their stats, which both represents his agile nature compared to other lords in the franchise, and the +2 in all of Marth's stats when he holds the Shield of Seals/Binding Shield in New Mystery of the Emblem.
    • He has Binding Shield, which allows him to follow-up, as well as prevent enemy counterattacks and follow-up if he's fighting a dragon. This is the opposite of the original effect of the Falchion in the Dark Dragon and the Sword of Light, where it prevented any enemy direct attacks, excluding dragons.
    • Him having Infantry Flash, which gives all infantry within 2 spaces of him the Flashing Blade effect, as well as his Exalted Falchion having +3 Spd, references Dancing Blade in Fates, which gives -1 Str but +3 Spd, and where it is inheritable to anyone, either through the Flashing Blade Scroll, or through the Lodestar class for males.
    • Legendary Marth is a Legendary Hero of Fire, referencing his status as the face of the Fire Emblem franchise, as well as the Fire Emblem itself that he carries.
  • Legendary Tiki's design is based on one of her TCG designs.
    • Her dragon form being gold instead of white is based on how she appears as a Divine Dragon in Book II of Mystery of the Emblem.
    • Legendary Tiki is a Legendary Hero of Earth, referencing the Earth Dragons in her home game, and that in one of her quotes in the Harvest Scramble in Awakening that she is "trapped down here on the earth, when all those I've loved are way up in the sky".
  • Gharnef has an average stat spread but also high speed, referencing his very high speed but very low stats in Shadow Dragon and the Sword of Light and its remake, to offset Imhullu giving him invulnerability against everything except Starlight.
    • Imhullu's effect at the start of turn 3 deals 5 damage and inflicts the no counterattack status on all enemies except tome wielders within 5 columns of where he is centered in, referencing both the Geosphere's and Starlight's effects, where when Geosphere in the first game and its remake (as well as the first book of Mystery of the Emblem) is used, it damages everyone but the user on the map, and the fact only tome wielders can use Starlight, the only weapon that can negate Imhullu's invulnerability effect.
    • Imhullu's attack animation is based on its animation in the original games instead of its animation in the remakes.
  • The exclusive refinement for Ogma's Gladiator's Blade grants him +4 Atk/Spd in combat if he is within 2 spaces of a flying or infantry ally, referencing his close bond with Caeda and his mercenary comrades Bord, Cord, and Barst.
  • The exclusive refinement for Palla's Whitewing Blade, Catria's Whitewing Lance, and Est's Whitewing Spear is Heroes' equivalent of the Triangle Attack. With this refinement, the Whitewings gain +3 in-combat Atk/Spd/Def/Res if there are at least two flying allies within two spaces of them. The Whitewings can also attack twice in succession if they initiate combat while meeting the flying ally requirement. In addition, the refinement's icon even has a triangle in it.
    • The Triangle Attack refinement being exclusive to the Whitewings may be due to the fact that they introduced the Triangle Attack, even though it has appeared outside the Archanea games.
  • Fallen Young Tiki is based on her antagonist appearance in Shadow Dragon (and to a lesser extent Mystery of the Emblem).
    • Her exclusive skill Solitary Dream comes from when she was induced a dream-based coma to prevent her from degenerating and later going berserk, with Gharnef weaponizing it to stop Marth and his army.
  • Phina wields a Rapier, referencing that in the original Mystery of the Emblem, alongside with Marth, she can wield rapiers, but loses the ability to do so in New Mystery of the Emblem.
  • Sirius wields the Sable Lance, which is named after the Sable Order of Knights of Grust in Shadow Dragon, who Camus leads, Sirius' original identity. The lance's design is based on the one he wields in his New Mystery of the Emblem artwork.
    • The Sable Lance granting +4 Atk/Spd/Def/Res during combat if the user is alone, as well as him having Atk/Spd Solo 3 in his default kit, references how he went on a solo mission to find Nyna.
  • Barst wields the Devil Axe, which gives +4 Atk/Spd/Def/Res during combat, but if the user attacks they receive 4 damage after combat, referencing the Devil Axe in most of the games, which is a powerful and easy to wield weapon, but has a chance to deal damage to the user equal to the damage supposed to be dealt onto the foe instead, with the chance decreasing the more Luck the user has.
  • Some characters have their artwork posed like in Mystery of the Emblem. Julian and Lena were posed like how they appear in their respective official artworks, while Castor, Vyland, and Spring Michalis reference their in-game portraits.
  • Julian is a dagger unit, referencing that he was in the Thief class in Shadow and Mystery of the Emblem.
    • He has Close Foil, which gives him +5 Atk/Def and allows him to counterattack at close range if the foe initiates combat and wields a physical weapon, referencing that he has strong Strength and Defense growths for a Thief in Mystery of the Emblem, as well as him using swords in the main games.
  • Male Kris wields a Sword while Female Kris wields a Lance, referencing their respective class options in New Mystery of the Emblem, with Male Kris could become a Mercenary, while Female Kris could end up as a Pegasus Knight.
    • Female Kris being an Infantry Lance reference how in the original Mystery of the Emblem that mounted units can dismount to remove their movement weakness, but also lose some stats and movement, where they are forced to do so in Indoor maps.
    • Male Kris' Accessory is Ymir's Cap, while Female Kris' Accessory is Masque Mask, referencing how in New Mystery of the Emblem, Kris can wear accessories for an entire chapter, and have the option to keep it for the rest of the game or remove it at the end of the following chapter, with Ymir's Cap gained at the end of Chapter 21: The Wyvern's Dale, and Masque Mask gained at the end of Chapter 10x: The Mask Laughs.
  • Pirate Darros' injured artwork is posed like the battle sprites of Pirates in Shadow Dragon and the Blade of Light and Mystery of the Emblem.
  • Halloween Xane's exclusive weapon allows him to copy the stats of allies within two spaces of him, referencing that in his home games, he is capable of transforming into a copy of another character. Much like in Mystery of the Emblem, he does not copy HP.
  • Wolf has Life and Death 4, referencing his ending in New Mystery of the Emblem where he gained a Death Seeker attitude after the death of Hardin.
  • Malice's Spendy Scimitar allows her to gain more stats if she has one or more Dragonflower boosts and ignore skills that inflict -1 special buildup on her and grant +1 special buildup on the foe if there is two or more Dragonflower boosts references her mercenary lifestyle in Archanea and New Mystery of the Emblem. The fact that she only requires 2 boosts references how she and her father Dice are automatically recruited in Chapter 10 of New Mystery of the Emblem when they only asked for 590 gold from Marth after the war.
  • Legendary Caeda wield the Wing-Lifted Spear, which deals effective damage against Armored and Cavalry units, referencing the Wing Spear she wields in Shadow Dragon and New Mystery of the Emblem, which also deal effective damage against Armored and Cavalry units.
    • Her design takes traits from both her appearances in Tokyo Mirage Sessions as a Mirage, as well as her Falcon Knight promotion in Warriors.
  • Medeus' Assured Rebirth allows him to reduces damage taken from attacks and non-Røkkr AOE special equal to 20% x the amount of Staff or Dragon allies within 3 spaces of him, referencing the 3rd part of "Light and Shadow" in Mystery of the Emblem, where he is surrounded by Nyna, Maria, Lena and Elice, all whom are brainwashed, and if he suffers enough damage he will consume one of them to recover to full HP.
    • His C skill is Canto Control, which limits the Canto movement of enemy units if they're within 4 spaces from the user. While there is no Canto mechanic in the Archanea games, Medeus is fought indoors in both books of Mystery of the Emblem, a condition that forces fliers and cavalry units to dismount in the original SNES version.
  • Hardin's Coyote's Lance grants himself and all Cavalry allies within 3 spaces of him +6 Atk/Spd and a status effect that allows the user to perform a guaranteed follow-up attack if the user initiates combat, referencing his bonds with the Coyote's Men/Wolfguard in Shadow Dragon and the Blade of Light/Mystery of the Emblem, which all are Cavalry units in those games.
  • Ascended Young Tiki's attire is based on the attire of both Young Marth and Young Caeda's attire in Heroes.
  • Gotoh wields the Brilliant Starlight, referencing that he created the tome Starlight from the Lightsphere and Starsphere to counter against Gharnef's Imhullu's immunity effect in Shadow Dragon and the Blade of Light and its remake, which is also referenced in Heroes where Brilliant Starlight makes the user able to counterattack regardless of status or foe's effects, whereas Imhullu inflicts [Flash] at the start of the user's 3rd turn and prevents the foe from counterattacking and grants the user Damage Reduction if the foe is not a Tome wielder.
    • Brilliant Starlight's regular attack animation is reminiscent of the NES version of Starlight, while its killing blow version, which summons the image of a miniature galaxy, is based on the remake's version.
  • Fallen Maria's Sacrifice Staff allows an ally within 2 spaces of her to gain +5 Atk/Spd/Def/Res during combat and the Miracle effect and 99 HP after combat if the Miracle effect was activated, referencing that in Mystery of the Emblem where if Medeus was defeated while Maria, Lena, Elise and Nyna are alive and are on his side, he revives at full HP and consumes one of them.
  • Attuned Caeda is an Infantry unit, referencing that in the original Mystery of the Emblem, mounted units are forced to dismount in indoor maps.

    • Alm has Windsweep, which the user only deals one attack if they initiate, but if the user is faster than the foe and they wield a physical weapon, the foe cannot counterattack, referencing the Combat Art Windsweep from the Iron Sword, where performing the Combat Art only allows the user to attack once, but also prevents the foe's counterattack, regardless of the enemy's weapons.

    • She has Double Lion, which gives her a brave effect when she attacks at full HP at the cost of 1 HP if she attacks, referencing the combat art of the Royal Sword in Shadows of Valentia.

  • Legendary Alm's attire is based on his Conquerer Overclass, which is a DLC class in Shadows of Valentia.
    • His Luna Arc is based on the Luna Bow in Shadows of Valentia, which also gives the Combat Art "Lunar Flash", his exclusive special in Heroes.

      • The 1~3 range of the lance.
      • The Passive skill Phantasm which reduces any damage from magic and bows by half.
      • Him sacrificing Rinea, his loved one, to Duma for more power.
    • He also has Warding Stance 4, which gives +8 Res during combat (as well as inflict -1 special buildup for the enemy) if he is attacked, referencing the +5 Def/Res Kriemhild gives.

    • The unique refine for Death allows her to warp to any space of an ally within 2 spaces of her, referencing how Witches in Gaiden and Shadows of Valentia can warp to an empty space to attack.
  • Brave Alm's armor is based on his official art in Gaiden, which is colloquially known in the community as his "dong armor".
    • His Dracofalchion grants him +5 Atk/Spd/Def/Res during combat if there is equal or more foes within 2 spaces of him to the number allies within 2 spaces of him references both the overwhelming odds against the Rigelian Army in Shadows of Valentia, as well as his descendant Walhart from Awakening having a weaker effect with his Wolf Berg in Heroes.
  • Berkut and Rinea having dancing variants references the cutscene where Fernand defects to Rigel and witnesses both Berkut and Rinea dancing together in Shadows of Valentia.
  • Forsyth wields the Sol Lance, which Sol is the rarest lance in Shadows of Valentia.
    • Sol Lance having a Life Drain effect references how in all other Fire Emblem games, the Sol skills recover the user's HP, all except Shadows of Valentia, where it did just pure damage increase instead with the Solar Thrust Combat Art.
  • The attire for Valentian Catria, Palla, and Est are based on the Falcon Knight uniform in Shadows of Valentia.
    • Valentian Catria and Palla being Sword Fliers references how Falcon Knights in other Fire Emblem games can wield swords as well as lances, but not in Gaiden and Shadows of Valentia.
    • Catria wielding the Astra Blade references the Astra in Gaiden and Shadows of Valentia, the rarest sword in those games.
    • That Astra Blade boost damage by 50% equal to the difference between the user's Atk to the enemy's Def if their Atk is higher references the Astral Blade Combat Art in Shadows of Valentia, where the user performs 5 attacks with 50% damage, whereas in Heroes, it is similar to the Glimmer Special, the sister skill of Astra.
    • Palla's Ladyblade inflicts -5 Spd on the user, but allows them to attack twice regardless of phase and targets the lower defensive stat of a foe during combat. This references the Ladyblade's Flamberge Combat Art in Shadows of Valentia, where the user can attack twice and deals magical damage to the foe.
    • Est is posed similarly to her Shadows of Valentia artwork.
  • Conrad having the Barrier Lance+ references how in Shadows of Valentia, he is tied with Est with the second highest base Resistance out of all the entire physical attack roster, and the second highest Resistance growth, both of which only being behind the DLC exclusive Emma from Fire Emblem Cipher fame.
  • Python being a Bow Cavalier references the class progression Archers go through in Gaiden and Shadows of Valentia, where their final class is a Bow Knight.
  • Legendary Celica's attire is based on her Rigain Overclass, which is a DLC class in Shadows of Valentia.

    • Her Mila's Turnwheel inflicts the Isolation status on foes within cardinal directions of her if they have lower Def than the user at the start of the user's turn, as well as adding +1 turns to the Timed Mission of Aether Raids if she is deployed in an offense team during Light seasons, references two things:
      • The Isolation references a cutscene in Shadows of Valentia where she uses her powers to attempt to repel Rudolf and his forces, as well as her attendants, but only Rudolf remains to face against her while wielding the Kingsfang Falchion.
      • The extra turn references the Mila's Turnwheel in Shadows of Valentia, where the player can revert time to gain a more favorable result in a battle, in this case more time to rout the enemy in Heroes.
    • Her Nurturing Breath gives all allies within 7 rows and 7 columns centered on the user +2 Atk/Spd/Def/Res during combat references in Gaiden and Shadows of Valentia that she advocates nurturing humanity in Valentia to making them strong as opposed to Duma advocating strength and hardships to make them strong, eventually splitting Valentia into Duma leading Rigel in the north, while Mila leading Zofia in the south.
  • Zeke wields the Holy Gradivus, referencing both the Gradivus can be obtained by either from the Duma Temple or by forging a Blessed Lance in Shadows of Valentia, and that Zeke was formerly Camus from Archanea, who originally wielded the Gradivus in Shadow Dragon and the Blade of Light and its remake.
  • Luthier is a Green Tome in Heroes, referencing that he starts with Excalibur in both Gaiden and Shadows of Valentia.
  • Tatiana has Blárrabbit+, which allows her to restore 7 HP after every first combat she participates in each player and enemy phase, referencing her wielding Nosferatu in Gaiden and Shadows of Valentia, where it allows her to restore HP equal to the damage the wielder deals per attack.
  • Fernand has Sworddbreaker, referencing his hatred for Alm, a Sword unit.
  • Rearmed Sonya's attire is based on the Enchantress attire in the DLC of Shadows of Valentia, which she can promote into the Overclass if she was maxed level in the Priestess Class and visits the Altar of the Sorceress.

      • The northern part of the Paralogue 13-1 map has an Axe Cavalier and a Mage, possibly representing Lex and Azelle respectively (both spawn on roughly the same spot in the chapter that inspired this map, the difference is that the Mage is Blue tome while Azelle is usually using fire magic and would be a Red tome).
    • Paralogues 13-2 (Od’s Swordswoman), 13-3 (Bound by Blood), Jamke's Grand Hero Battle, Seliph and Deirdre's Bound Hero Battle, and Legendary Deirdre's Legendary Hero Battle maps are based on Chapter 1 (Girl of the Spirit Forest) of Genealogy of the Holy War..
    • Arvis's Grand Hero Battle map and the final map of Tempest Trials+: "Dancing Affinity" is based on the events of the Battle of Belhalla in Genealogy of the Holy War. Only now the player is in control rather than the event playing out automatically in Arvis' favor.
    • Genealogy of the Holy War's Final Chapter (The Last Holy War) is used as the basis for several maps due to its size:
      • Castle Friege was featured on Ishtar and Reinhardt's Bound Hero battle.
      • Castle Velthomer was featured on the final map of Tempest Trials: "Genealogy of Light". Julia being the boss references her being brainwashed by Manfroy before being dispatched to fight Seliph's forces.

    • Travant's Grand Hero Battle map is based on the left side of Chapter 9 (For Whose Sake) of Genealogy of the Holy War. The same map is used for Arion's Grand Hero Battle map. The Thracia Castle part of the same chapter is also used for Leif & Altena's Bound Hero Battle map.
    • Lewyn and Sigurd's Bound Hero Battle map is based on Silesse Castle of Chapter 4 (Dance in the Skies) of Genealogy of the Holy War.

    • Silvia and Erinys' Bound Hero Battle map is based on Castle Mackily of Agustria of Chapter 2 (Disturbance in Agustria) of Genealogy of the Holy War.
    • Leif and August's Bound Hero Battle map is based on Chapter 19 (Remorse and Retaliation) of Thracia 776.

    • Ced & Asbel's Bound Hero Battle map is based on Chapter 4x (The Hero of Winds) of Thracia 776.
  • Arden's Follow-Up Ring skill is a nod to Genealogy of the Holy War where he could obtain the ring if moved to just the right spot in Chapter 2. Likewise, Arvis' Recover Ring was an item in his inventory during the prologue.
  • Much of what Seliph tells the player in their level 40 conversation comes from his secret event with Muirne in Genealogy of the Holy War, notably the parts where he states that he wish he could just run away and that he still keeps fighting despite his fear.
  • Seliph states that he'd like to stroll through a market with the player, calling back to when he says as much to Julia in Chapter 9 of Genealogy of the Holy War.
  • One of Ayra's quotes has her express confusion when called "ladylike", which is what she does in her lover's conversation with Arden in Chapter 5 of Genealogy of the Holy War. Another line has her decline a gift, telling your to give it to a girl who would like it, referring to her Chapter 3 conversation with Lex.
    • Ayra's Blade's design is identical to the sword Ayra wields in the TCG.
  • Arvis' readying stance once a turn begins is the same stance from his Super Tactics Book artwork. Like Sigurd, his outfit is closely based off the Super Tactics design instead of the TCG's.
  • The effects of the divine weapons see certain degrees of replication in Heroes:
    • Sigurd's default special skill is Miracle. In Genealogy of the Holy War, Tyrfing granted its wielder the Miracle skill, and while it functioned differently then, it was still a skill instrumental in keeping a character alive when near death. Additionally, the Divine Tyrfing cuts damage taken from the first magic attack by 50%, referencing the fact that it granted its wielder +20 Resistance when equipped.
      • Additionally, Regular Seliph's refined Tyrfing and Brave Seliph's Holytide Tyrfing has Miracle built into it, provided that he is at 50% HP or over and 25% HP or above at the start of combat, respectively.
      • Legendary Seliph's Virtuous Tyrfing grants the user +3 Res and inflicts -6 Atk/Def on the enemy, as well as healing the user 7 HP for every attack the user does.
      • Legendary Sigurd's Hallowed Tyrfing grant the user -1 special cooldown, and if the foe is at 75% HP or above at the start of combat, the user gains +5 Atk/Spd/Def/Res, a guaranteed follow-up attack, and 40% damage reduced from the foe's first attack if either the user initiates combat or the foe is a ranged unit.
    • Mystletainn originally gave +20 Skill and +10 Resistance to its wielder, as well as the Critical skill, which was necessary to inflict critical hits (unless the hero was using a weapon with 50 or more kills on it). In Heroes, it reduces Regular Eldigan's maximum special cooldown by 1, and the unique refine gives him +3 Atk/Spd/Def/Res at the cost of 6 damage inflicted on him after combat.
      • Dark Mystletainn, while giving the same effect as the unrefined Mystletainn, also gives the user -2 special cooldown cooldown after combat whenever the user activates their special either before or during combat.
    • Valflame granted its wielder +10 Magic, +10 Defense, and +10 Resistance. That effect is represented in Heroes by giving the unrefined tome an innate combination of Atk Ploy 2 and Res Ploy 2, and refined version inflicting -5 Atk/Res on all foes within 3 columns or 3 rows centered on the user.
    • All versions of Naga deal bonus damage to dragons. While this effect is Awakening-exclusive and not in Genealogy of the Holy War, they serve as a reference to the fact that the Big Bad was, in truth, a dragon who had possessed a compatible human.
      • Julia's version of Naga grants her +2 Def/Res (+4 on refine) during the enemy phase, a reference to how Naga grants its wielder +20 Defense and Resistance in the original game, and +5 Defense and Resistance in Awakening.
      • Deirdre's Divine Naga ignores visible buffs on the enemy (specifically buffs that visibly change the numbers), which can be seen as a reference to how Naga could bypass Loptous' defensive effect (halving enemy's attack power). Additionally, the unique refine gives her +3 Atk/Spd/Def/Res if she has 3 Res higher than her opponent, referencing the +20 to Skill, Speed, Defense and Resistance the Book of Naga gave in Genealogy of the Holy War. This effect is later referenced by Light and Dark (as well as its upgrade Light and Dark II), a B skill exclusive to Julia's variants.
      • Legendary Julia's Virtuous Naga gives her +3 Atk, and if she has more Atk than the foe at the start of combat, she inflicts -6 Atk/Res on the foe during combat.
    • Mjölnir originally gave +20 Skill and +10 Speed in Genealogy of the Holy War. In Heroes it instead gives -1 maximum special cooldown, and gives +6 Spd during combat if the user initiates combat (or if the user is not adjacent to an ally on refine), and an additional +5 Atk/Spd during combat and ignore skills that deny any of the user's follow-up attacks if the user either initiates combat or is not adjacent to an ally with the unique refine.
      • Ascended Ishtar's Thunder's Mjölnir has the -1 maximum special cooldown effect as well as giving +6 Atk/Spd to the user during combat and ignore skills that inflict -1 special buildup on the user and grants +1 special buildup on the foe if the user is at 25% HP or above at the start of combat.
    • Loptous granted the user +5 Resistance and halved the enemy's attack before defensive stats are calculated. In Heroes, it instead give +3 Res and gives the enemy -6 Atk and the refined version also inflicts -6 Res as well and gains the Dragon Wall effect, if they did not have an effective bonus against dragons, and the unique refine allows him to inflict -5 Atk/Res to foes who have lower Res than him and are adjacent to another foe at the start of his turn and if he is at 25% HP or above at the start of combat he inflicts a further -5 Atk/Res on his foe during combat, while the user also is counted as a dragon, rendering the user weak against dragon-slaying weapon users like the Naga users in Genealogy of the Holy War.
      • Loptous granting the user a dragon weakness currently make them weak to any form of Naga, any form of Falchion, any of Tiki and Nagi's personal breaths, and Naga herself and anyone affect by Divine Fang's status effectnote . This is due to lore that the Falchion is forged out of Naga's fang, as well as Tiki being the daughter of Naga and Nagi possibly being a reincarnation of Naga.
    • Gáe Bolg originally grants the user +10 Strength, Skill, and Defense in Genealogy of the Holy War. In Heroes, it grants +5 Atk/Def when the enemy is an Infantry, Cavalry, or Armored unit, and the unique refine gives an additional +5 Atk/Def if there is a Sword, Lance, Axe, or Cavalry ally on the user's team.
      • Earthly Gáe Bolg inflicts on the enemy -5 Atk/Def, as well as negating any bonuses on those stats during combat, if the enemy is an Infantry, Cavalry, or Armored unit.
    • Gungnir originally gave the user +10 Strength, Speed and Defense. Arion's Heired Gungnir instead grants +6 Atk/Def at the start of the user's turn, as well as +5 Atk/Spd/Def/Res during combat and deals true damage equal to 15% of the user's Def during combat if the user is at 25% HP or above at the start of combat.
    • Forseti originally gave +10 Skill and +20 Speed in Genealogy of the Holy War. In Heroes, it instead grants +3 Spd and have any follow-up attacks go before the enemy counterattacks if the user initiates combat and is at half HP or over at the start of combat with the unrefined version, allows the user gain +4 Atk/Spd during combat and have any follow-up attacks go before the enemy counterattacks if the user initiates combat and is at 25% HP or more at the start of combat with the refined version, and the user gains an additional +4 Atk/Spd during combat, as well as ignoring any debuffs on the user's Atk and Spd and any buffs on the foe's Atk and Spd if the foe is at 75% HP or more at the start of combat with the unique refine.
      • Ascended Ced's Heired Forseti grants -1 maximum special cooldown, +6 Atk/Spd and -1 special cooldown at the start of the user's turn if the user is at 25% HP or above, and +6 Atk/Spd during combat, reduces damage taken from the foe's first attack by 30% and deals true damage equal to X%, where X = 10 x the user's maximum special cooldown, +20, if the user is at 25% HP or above at the start of combat.
    • Balmung originally gave +10 Skill and +20 Speed in Genealogy of the Holy War. In Heroes, it instead grants +3 Spd and gives the user +5 Atk/Spd/Def/Res during combat, as well as negating any penalties the user has if the foe either initiates combat or is a full HP at the start of combat.
    • Yewfelle originally gave +10 Strength and Speed in Genealogy of the Holy War. In Heroes, the Holy Yewfelle instead gives +6 Atk/Spd during combat to the user as well ignore any penalties to the user's Atk and Spd during combat if either the user initiates combat or the foe is at 75% HP or above at the start of combat, and Heired Yewfelle, in addition to granting +5 Atk/Spd/Def/Res during combat, also grants Atk/Def during combat equal to 25% of the foe's Atk, -8, with a minimum of 0 and maximum of 10, if the user either initiates combat or is within 2 spaces of an ally.
      • Ullr, the wielder of Holy Yewfelle in Heroes, also has Life and Death 4 as her default A skill, which gives +7 Atk/Spd but inflicts -5 Def/Res, also referencing the +10 Strength and Speed Yewfelle gives.
      • Febail's Heired Yewfelle also recovers 7 HP after combat if the user either initiates combat or is within 2 spaces of an ally, referencing that Yewfelle's Renewal effect in Genealogy of the Holy War.
  • Julia's default special skill is Dragon Fang, a reference to her possessing Major Naga holy blood. The same can be said for Julius, who has Draconic Aura as his default special skill, referencing his Major Loptous blood.
  • Tailtiu's Tome of Thoron has the Heroes effect of Wrath, referencing both that she starts with Thoron when she joins, and that she has the Wrath skill by default in Genealogy of the Holy War.
    • Tome of Thoron's unique refine gives her +6 Spd when she initiates combat, both referencing the Adept Skill that she gets when she promotes into the Mage Fighter, and being similar in effect to Mjölnir in Heroes, which while she has Thrud blood, it's only minor and as a result she does not have the potential to wield it.
  • Part 5 of Book II Chapter 7 (the first chapter focusing on Thracia 776 characters) plays much like an Escape map from Thracia (with the player starting right next to Surtr and having to do their best to stay ahead of him, while also fighting enemies in front)
  • Leif has S Drink as his B skill, which restores 99 HP and reduces his special cooldown by 1 on the first turn of battle. In Thracia 776, Leif is the only character NOT affected by the fatigue system.
    • In addition, the S Drink was an actual consumable item in Thracia 776, which refreshed a character's fatigue to zero when used. Ironically enough, this meant Leif was the only character who couldn't benefit from using S Drinks, even though no one else can inherit the skill in Heroes.

  • Amelia is an armored unit, referring to her having access to the armored Knight class line.
    • Amelia's axe is chained to her armor, referring to how Generals do the same thing with their lances and axes in the GBA titles. Her shoulder pads also matches those Generals, only a lot smaller.

  • Joshua wields Audhulma, the Sacred Twin weapon of Jehanna, which was given to him by his mother in The Sacred Stones on Eirika's route.
    • When Joshua attempted to goad Dorcas into making a bet, he made a reference to a friend of his that got himself killed. He was referring to Caellach, who got himself killed by facing Eirika/Ephraim's army (or in Eirika's scenario, killing Joshua's mother, so he ended up exacting vengeance on Caellach).

  • The ending of Tempest Trials: "Less Than Heroic" has Joshua promise to waive the fee or the IOU for Marth if he can guess heads or tails. Marth initially guesses heads before hurriedly changing to tails, just like Natasha did under the same circumstances in Sacred Stones.
  • The Bound Hero Battle involving Tana and Amelia, despite both of them not being that heavily connected, stems from the fact that they're recruited in the same chapter right after Eirika and Ephraim go their separate ways. The map itself is based off of Eirika's version of that chapter: Chapter 9, (Distant Blade). It may also be based on the fact that their roles were swapped in the Beta version, with Amelia being the princess of Frelia and Tana being a General.
  • Seth has the Pre-Mortem One-Liner "I admire your professionalism." This is a nod to a line he had in Eirika's Chapter 9, where he was interrogating a random mercenary who had been hired to kill Eirika.

    • He has Swap, referencing before his scripted fight against Valter, he swapped positions with Eirika to protect her.

    • Valter's special activation quote "You're just a corpse" is also something he said before his scripted battle with Seth.
  • Sacred Memories Eirika's Armor is based off her Beta armor, and the fact that she uses a tome could be a reference to a glitch in Sacred Stones that would allow anyone to gain ranks in Dark Magic.
    • Her design, including her horse attires, resembles the Mage Knight's design in The Sacred Stones.
  • In Fallen Lyon's S-Rank with Regular Lyon in the "Peaceful Ends" Forging Bonds, Lyon states that he is Fallen Lyon's future and not the other way around, referencing how Lyon is made playable (and thus free of the Demon King's influence) in the Creature Campaign in The Sacred Stones, which is available after beating the game and the Demon King.
  • Legendary Ephraim is the Legendary Hero of Fire. In The Sacred Stones, Ephraim's affinity was Fire.
    • Legendary Ephraim's weapon, the Flame Siegmund, allows him to attack twice if Ephraim has more enemies than allies within 2 spaces. This is a reference to his infamous attack on Fort Renvall, where he captured the fortress with only 3 other knights.
    • His default B skill is Solar Brace, referencing his personal promotional item that allows him to promote into the Great Lord class in The Sacred Stones, which his Legendary version is based on in Heroes.
  • Legendary Eirika is the Legendary Hero of Water. This is more in line of her sword being called the Storm Blade and the moon's association with tides.

  • Both the Flame Siegmund and Storm Sieglinde have +3 Atk built into them, referencing the +5 Str both those weapons have in The Sacred Stones.

  • Brave Ephraim's appearance is based on his father, Fado.
    • Brave Ephraim being an armored unit is due to his father being an armored unit in Sacred Stones when he's playable.
    • Him wielding Garm, one of Grado's Sacred Twins, references that he was taught how to wield a lance from Duessel, one of the generals of Grado and a potential wielder of that axe.
  • The exclusive refinement for Vidofnir grants Tana +4 Atk/Spd during combat if she is within two spaces of an infantry or armored ally, a likely nod to her Sniper brother Innes and the dependable Knight Gilliam. Tana, Innes, and Gilliam also all hail from the same country—Frelia.
  • The order the Magvel characters are sorted in the Catalog of Heroes is the same order their countries of origin are visited in Ephraim's route, being Renais, Frelia, Grado, Jehanna, Rausten, and finally the Darkling Woods.

  • The "Mercanary Matters" Forging Bonds begins with Ephraim and Lyon joining Gerik's Mercenaries, despite the latter being concerned for the former neglecting his political duties. Ephraim does not bother using an alias and Ewan notes he has the same name and appearance as the prince of Renais. Joshua had done the same thing in running away from his kingdom and becoming a mercenary with little effort to conceal his identity.
  • Fallen Lyon's appearance is based on how he was possessed by the Fomortiis during the later chapters of The Sacred Stones.
    • The attack animation of Fallen Lyon's Blood Tome is based on the Fomortiis's physical attack Ravager in The Sacred Stones.

  • Duessel's Obsidian Lance grants him a follow up attack and inflicts -6 Atk/Def on his foe if he is next to no ally. This effect is quite similar to Legendary Ephraim's Flame Siegmund. Duessel taught Ephraim in the way of the lance, so all of the guaranteed follow up attacks that each Ephraim can do could be in reference to his teacher who can do that and then some.
  • Knoll's connected accessories in Forging Bonds resemble the Bael and Elder Bael monsters in Magvel.
  • In "Driven by Vision" Forging Bonds, Duessel recounts a story Knoll shared with him regarding two starving men and a single loaf of bread. This same story was in one of Knoll and Duessel's support conversations in The Sacred Stones.
  • Marisa has unique attack and special art, where she wields her sword in her right hand in the former and switches to her left hand in the latter. This references a support conversation with Tethys in The Sacred Stones where she says she is ambidextrous but prefers her stronger left hand.
    • Marisa initially wielded the Wo Dao and was given Shamshir as her own unique weapon in a later update. While Shamshir was originally just The Sacred Stones' version of the Wo Dao and usable by all Myrmidons, Swordmasters and even Eirika, it is usually associated with Marisa because she carries one by default and is associated with her homeland Jehanna. In line with Marisa's origin as Critical Hit Class, the Heroes version combines the effects of both the Wo Dao (additional damage when Special triggers) and Killing/Slaying Edge (Special cooldown count -1).
  • Young Duo Eirika & Ephraim has Ephraim wielding a rapier like his sister, referencing that in The Sacred Stones Ephraim used to train with swords when he was younger, before he found out the advantages of spears over swords when he was training with Duessel in his A support with him.
  • Ascended Joshua has Green Feud, where it inflicts -4 Atk/Spd/Def/Res as well as ignore skills of any of the foe's allies during combat if the foe is Green, as well as ignore skills from any foe's Green allies during combat, referencing his hatred and revenge against Caellach for murdering Joshua's mother Ismaire in The Sacred Stones, who is a Green Axe in Heroes.
    • His attire references the Assassin attire in the GBA games, which he can also promotes into.
  • In "New Foundations" Forging Bonds:
    • Colm brags about his thieving skills and cites the time he stole Eirika's bracelet. He also mentions how his and Neimi's village burned down.
    • Joshua involves Gerik in his conversations and makes many references to their support conversations, such as Gerik being able to spot Joshua's cheating when they gambled, their discussion about luck and skill, and how Joshua wanted Gerik as his Number Two after the war. Joshua also makes reference of what happened to Jehenna, namely the death of his mother, betrayal of a close ally, and the palace burning down.
    • Neimi mentions her grandfather was able to use a single arrow to hunt game, which she had mentioned before in a support conversation.
    • Rennac is looking for ingredients for a recipe he has, which involves michew berries that Neimi and Amelia are familiar with, as they had a support conversation about them.
  • Fomortiis being an Armored Beast unit makes him able to counterattack ranged foes if he is transformed, as well as his low movement, references that in addition to having Ravager as his close range weapon, he also has Demon Light, which is a 1~3 ranged weapon, and that he has only 2 movement in The Sacred Stones.
    • His Ravager inflicting -6 Atk/Def on the foe during combat, inflicting -1 special buildup, and granting him +1 special buildup if he is transformed, as well as his Nightmare inflicting -10 Atk/Def on the foe during combat and ending the turn of the nearest foes that can act within 4 spaces of his target after combat references a few things in The Sacred Stones:
      • The +15 Strength/Skill/Defense and +10 Resistance of Ravager and the +10 Strength/Skill/Defense/Luck and +15 Resistance of Demon Light.
      • The Nightmare staff he is equipped with to inflict the Sleep status to all foes within 3 spaces of him if there are 6 or more enemies are near him.
  • Gilliam's Frelian Lance (not to be confused with Young Tana's Lance of Frelia) grants all flying allies within 2 spaces of him the Iote's Shield effect for 1 turn when his turn begins, referencing how his home country of Frelia is home to Magvel's Pegasus Knight trio.
  • In "Her Shining Future" Forging Bonds:

    • Gilliam is involved in arm-wrestling matches with other heroes, which references his support conservations with Garcia, of which the latter's son mentions their matches.

    • Vanessa tries to learn magic after Lute suggests studying under Merric, which harkens to a support conversation with Lute, where she mentions having an interest in magic but lacked talent.

    World of Tellius (Path of Radiance and Radiant Dawn
  • Chapter specific:
    • Chapter 10-5 (Radiant Mercenaries) is based on Chapter 8 (Despair and Hope) of Path of Radiance. Interestingly, while it was a Hold the Line chapter for Ike's group in Path of Radiance, the reverse is true for your group in Heroes. The same chapter was later used as the basis for the final map of Tempest Trials+: "A Child's Wish" and Emblem Ike's Emblem Hero Battle.
    • Chapter 13-1 (Bruno’s Secret) is based on Chapter 4 (Roadside Battle) of Path of Radiance.
    • Chapter 13-2 (A Triple Decker) is based on Chapter 13 (A Guiding Wind) of Path of Radiance.
    • Chapter 13-3 (Shadow over the Port) is based on Chapter 11 (Blood Runs Red) of Path of Radiance. The final map of Tempest Trials+: "Greil's Request" also uses the same map, albeit decorated for the Valentine event.

    • Naesala's Grand Hero Battle map is based on Chapter 19 (Entrusted) of Path of Radiance.
    • Elincia's and Nephenee's Bound Hero Battle map is based on Chapter 3-10 (The Heart of Crimea) of Radiant Dawn.
    • Yune's Mythic Hero Battle map and Pelleas' Grand Hero Battle map are based on Part 3 Epilogue (From Pain, Awakening) of Radiant Dawn.
    • Haar's Grand Hero Battle map is based on the left side of Chapter 23 (The Great Bridge) of Path of Radiance, while Petrine's Grand Hero Battle map is based on the right side of the same chapter.
    • Titania and Mist's Bound Hero Battle map is based on Chapter 9 (Gallia) of Path of Radiance.
    • The final map of Tempest Trials+: "A Hero's Mettle" is based on Part 3 Chapter 13 (Blood Contract) of Radiant Dawn.
    • Caineghis and Tibarn's Bound Hero Battle map is based on Part 3 Chapter 8 (Incandescent Glow) of Radiant Dawn.
    • Altina's Mythic Hero Battle map is based on Part 4 Epilogue 1 (Rebirth) of Radiant Dawn. The same map, albeit modified, is also used for Tibarn & Nailah's Bound Hero Battle map.
    • The final map of Tempest Trials+: "A Waltz Unending" is based on Part 1 Chapter 4 (A Distant Voice) of Radiant Dawn.
    • The final map of Tempest Trials+: "Burden of Gifts" is based on the balcony of Mainal Cathedral in the Begnion capital of Sienne from Radiant Dawn.
    • Ranulf and Lethe's Bound Hero Battle map is based on Chapter 10 (Prisoner Release) of Path of Radiance.
    • Ashera's Mythic Hero Battle map is based on Part 4 Epilogue 5 (Rebirth) of Radiant Dawn.
      • The 2 Knights adjacent to her with the Near and Far Save skills reference the Aura that surrounds Ashera that protects her while also counter their foe equal to half the damage they, and removing all of them allows Ashera to be vulnerable.
    • Shinon and Gatrie's Bound Hero Battle map is based on Chapter 3 (Pirates Aground) of Path of Radiance.
      • The other three units alongside them on Hard and Lunatic difficulties represent the other members of the Greil Mercenaries, with the Sword Fighter being Ike, the Axe Cavalier being Titania, and the Cleric being Rhys.
    • The finam map of Tempest Trials+: "Breadwinners" is based on Chapter 3 (Pirates Aground) of Path of Radiance.
    • Fallen Muarim's Grand Hero Battle map is based on Part 1 Chapter 8 (Glory Unwanted) of Radiant Dawn.
    • Ludveck's Grand Hero Battle map is based on Part 2 Endgame (Elinica's Gambit) of Radiant Dawn. The same map, albeit modified, is also used for Legendary Elincia's Legendary Hero Battle map.
  • Elincia has Ardent Sacrifice, which heals an ally by 10 HP while subtracting 10 from her own, referencing that she can heal allies with staves while also wielding swords as her weapon in her home games.
  • Elincia and Nephenee having a Bound Hero Battle may reference Dummied Out data in Path of Radiance that implies the two were planned to have support conversations.
  • The Black Knight's appearance in 13-3 and how he leaves a house a few turns after the mission starts reflects how he appears mid-mission in the same Path of Radiance map that inspired the map layout.
  • Brave Ike's Beorc's Blessing skill is based on the Laguzguard in Path of Radiance, an item that when equipped halves damage taken from laguz units. Since beast units weren't introduced yet at the point Brave Ike was introduced, the skill nullifies direct buffs on flying and cavalry enemies attacking him.
  • At the end of Tempest Trials: "Moment of Fate", Ike and Mist talk to Masked Marth about the Black Knight, at which point Ike guesses that it wasn't truly the Black Knight, at which point Masked Marth confirms it to be true. In Radiant Dawn, the Black Knight survived his final battle with Ike in Path of Radiance, and in the original translation of the game, it was because his Warp Powder malfunctioned, sending his spirit to fight Ike, very much a similar explanation for the Black Knight players fight in Heroes.
  • Zelgius' armor is busted up, showing that this is his post-Ike duel self.
    • Zelgius having Warp Powder as his B skill references the warp power he wields in the Tellius titles, where he can teleport to other locations without using the Rewarp staff. The 80%+ HP requirement is also referencing how the warp powder exhaust the user after being used, likely as a self limitation for Zelgius to prevent use at a weaker state where he is more vulnerable.
    • Zelgius' special activation quotes "No draw. No escape." and "One will live. One will die." references his dialogue in Part 4 Epilogue-2, and his Duel to the Death with Ike, with him and Ike isolated by a magic barrier, allowing no escape for the both of them or having any allies assist them.
      • One of his other special activation quotes, "Let's see how you handle this", is from his pre-battle quote with Ike.
  • Legendary Ike is a Legendary Hero of Earth. In his home games, Ike possessed the Earth affinity.
    • Legendary Ike's special attack art shows Ragnell cloaked in blue flame, much like Ike's final attack in Radiant Dawn and his Eruption and Great Aether attacks in Super Smash Bros. for Nintendo 3DS/Wii U..
    • Some of Legendary Ike's special quotes are based on his boss dialogue in 3-13, specifically "I'll strike you down with one blow,"note  and "I won't have mercy on my enemies."note 
    • One of Ike's quotes "I've had pain, I've had suffering, and I have gotten up and moved on," is based on his special boss conversation against Sephiran.
    • His castle quote "People aren't perfect. We all make mistakes. But we also love our families and our friends... We should never forget that we all have that same capacity for love," is based on a line on his confrontation against Ashera in the Japanese script of Radiant Dawn.
  • In both Zelgius' and Legendary Ike's artwork, both Alondite and Ragnell are slightly damaged, with scratches and chipping shown on each blade, referencing their intense duel in Path of Radiance, especially in this art, while also referencing how it is downplaying Like Cannot Cut Like, leading to Ragnell's Excalibur in the Rust appearance in Awakening.
  • In Paralogue 20-2, Bridal Sanaki trips over her dress during the end dialogue. This is a reference to a conversation in Radiant Dawn, where Sigrun recounts that Sanaki tripped over her own dress multiple times during her coronation.
  • Titania wielding the Emerald Axe*, as well as her Draconic Poleax having the same effect, references the poleaxes from Radiant Dawn, which are heavier and less accurate, but stronger than the regular axes in that game.
  • The opening and ending cutscenes as well as the name of Tempest Trials+: "Chaos Named" are references to part 4 of Radiant Dawn with Micaiah making reference to Yune and the Black Knight saying that Micaiah's path lie with the goddess of chaos (Yune).
  • Tibarn has Sturdy Impact, which allows him to have +6 Atk, +10 Def, and negates any enemy follow-up attacks, referencing both his Pavise and Tear skills in Radiant Dawn, which Pavise allows him to ignore any damage done to him if it activates, and Tear halving the enemy's Speed and tripling the user's Strength when it activates.
    • Tibarn’s EX accessory is a bundle of three feathers representing himself and his companions, Janaff and Ulki.
  • Leanne and Reyson can attack in this game, referencing the Card items in Radiant Dawn which allows the user perform a magic attack, even those who normally cannot.
    • Both have Heron Wings, which at the start of their turn, recover 7 HP to all allies within 2 spaces of them, referencing their Blessing skill exclusive to Herons, which restores HP to all adjacent allies equal to their Magic.
    • Reyson being a green unit may be a nod to a scene in Path of Radiance where he punched Oliver in the face. Since Oliver is a blue unit in this game, that means Reyson still has the advantage.
  • Nailah has Glare, which inflicts the Gravity status to the enemy and any others adjacent to them after combat if she attacks. While it is named after her personal skill Glare, which petrifies her enemy if it hits, it's actually closer to the Howl skill, which on activation from indirect attacks inflicts paralysis on the enemy after combat.
    • She also has Distant Counter, referencing the Quickclaw skill, which on Speed% activation from indirect attacks, inflicts damage to the enemy equal to the user's Strength.
  • All infantry beasts when transformed gain +10 damage on combat skill activation, referencing the Savage Skill they can have, which triples their Strength and halving the enemy's Skill for one turn on activation.
  • Naesala has Growing Wind, referencing the Vortex skill he has in Path of Radiance, which on command allows him to attack using wind magic, even at range, but cannot be used defensively.
  • Valentine Greil has Fury 4, referencing his berserk rampage due to accidentally grabbing Lehran's Medallion in his backstory in the Tellius games.
  • Yune is a Mythic Hero of Dark, due to her being slandered as a Dark God by Dheginsea to prevent her from prematurely awakening from Lehran's Medallion.
    • She is a Flying unit due to her other form being the orange bird that accompanies Micaiah.
    • Her exclusive skill Chaos Named is named after the title of Part 4 Prologue of Radiant Dawn, where she properly introduces herself as Yune, rather than the Dark God.
    • The art of Chaos Named is from the energy orb that Ashera is showing in her Radiant Dawn official art, referencing their relationship as two halves of Ashunera, the creator and goddess of the land Tellius.
  • Mordecai has Smite, which he has by default in his skill kit in his home games.
  • Lethe's Brazen Cat Fang gives her +6 Atk/Spd during combat, as well as the skill Spd/Def Solo, which gives +6 Spd/Def during combat, with both of the conditions being that the user must not be adjacent to an ally, referencing her initial harsh nature to others, as well as not sharing her king and superior's goals in their co-existence with Beorc/Humans at first in Path of Radiance.
  • Ranulf's Covert Cat Fang gives him and any allies within 2 spaces of him +3 Atk/Def during combat if there is an ally within 2 space, referencing his friendly nature with others, even other Beorcs, in his home games.
  • Haar wields a Brave Axe by default, referencing that he started with one when he is recruited in Path of Radiance.
    • Haar has Guard, referencing the Guard skill he has (which is later called Cancel in Radiant Dawn), which negates an enemy attack by a percentage chance every attack, in the Tellius saga.
    • He later received a unique axe in Tempest Claw, which neutralizes his archer weakness, but instead makes him weak to blue tomes, which is in reference to the fact that Wyvern Riders in Radiant Dawn have no weakness to archers unlike other flying units, and instead have a weakness to Thunder Magic (which is usually classified as Blue in Heroes).
  • Tanith's Bridal variant has Harsh Command+, which is an upgraded version of Harsh Command, referencing her strict policies and command as one of the leaders of Begnion's Holy Guard, best demonstrated with her support with Marcia.
  • Sigrun's Bridal variant has Ardent Sacrifice, referencing her kind and generous nature compared to Tanith, best demonstrated with Sigrun allowing her subordinate Marcia to leave the Holy Guard to find her brother.
  • The unique refine for Oscar's Loyal Greatlance grants any Infantry and Cavalry allies within 2 spaces of him +3 Atk/Spd, as well as granting himself +3 Atk/Spd if he is within 2 spaces of an Infantry or Cavalry ally referencing his close relationship with the Greil Mercenaries (which are mostly made of Infantry and Cavalry units), especially his younger brothers Boyd and Rolf, a Fighter/Warrior and Archer/Sniper, respectively, as well as his friend and Unknown Rival Kieran, an Axe Cavalier/Paladin. it also references how him and his brothers can perform a triangle attack if all three use a Bow.
  • Brave Micaiah's attire is based on the Light Priestess class, her final exclusive tier class, in Radiant Dawn.
    • She has the spirit of Yune with her, and even shares the same movement class and weapon type as Yune, referencing that at the end of Part 3 and the rest of Part 4 of Radiant Dawn, Micaiah became the vessal of Yune.
  • Altina's A skill, Ashera's Chosen, only increases her Attack and Defense if she's alone, unless the only units she's adjacent to are dragons or beasts. Altina fought alongside Soan and Deghinsea, a lion Laguz and dragon Laguz respectively, as Ashera's Three Heroes.
    • She is a Mythic Hero of Astra, referencing her connection and blessing from Ashera, who has the Heaven affinity, close to Astra in Heroes.
  • Fallen Ike is based on his 'Cipher card art, where he touches Lehran's Medallion as part of a What If? scenario.
  • Ashnard is based on his appearance in the Hard and Maniac difficulty of the Epilogue of Path of Radiance, where he revives himself by touching Lehran's Medallion.
    • His Gurgurant grants him +3 Def, removes his flying weakness, and inflicting -5 Atk/Def on any foe within 2 spaces of him during combat references 3 things in the Tellius games:
      • The +3 Def, no flying weakness, and -5 Atk/Def references how he has blessed armor like the Black Knight in Path of Radiance, where only Ike's Ragnell, Dragon and the Royal Laguz, and certain S-Ranked weapons can damage him.
      • The no flying weakness references how in Radiant Dawn Dragoknights, Dragonmasters, and Dragonlords are not weak to Bows and Wind magic, but to Thunder magic instead, which is blue in Heroes.
      • The -5 Atk/Def to all foes within 2 spaces of the user during combat references the Daunt skill, which inflicts -5 Hit/Critical to all foes within 3 spaces of the user, which Ashnard has in Path of Radiance.
    • Him having Dragon Fang alludes to how unlike other Wyvern Riders, Ashnard is fighting atop a Dragon Laguz and not a Wyvern.
  • Rafiel is an infantry unit, unlike his siblings Reyson and Leanne who are both fliers (and therefore unable to naturally move one more space). This is in reference to how he's unable to fly in Radiant Dawn, which prevents him from catching up to his allies so quickly.
    • His Groom's Wing grants -1 Special charge to his support partner, a reference to the Bliss Galdrar ability. Bliss boosted an ally's Biorhythm rate, and a higher Biorhythm means a higher chance of activating skills, which would be represented through Specials in Heroes.
  • Ilyana wields blue magic in Heroes, referencing that she is a Thunder Mage in Path of Radiance and a Thunder Sage in Radiant Dawn.
  • Shinon has Deadeye, which allows the user to deal double damage as well as ignore any non-special percentage-based Damage Reduction skills, referencing his access to Deadeye in the Tellius games, which is gained through the Occult Scroll in Path of Radiance, and if he is promoted to a Marksman in Radiant Dawn.
    • Shinon wields the Double Bow, which gives him -1 special cooldown, and +5 Atk/Spd/Def/Res and Close Counter if he's not adjacent to an ally, as well as having Atk/Def Solo 4, referencing three things:
      • The Double Bow having 5% crit rate in Radiant Dawn and 10% crit rate in Awakening.
      • That Shinon fights along against the Greil Mercenaries and the Crimean Army in Chapter 18 of Path of Radiance.
      • The 1~2 range of the Double Bow in Radiant Dawn.
  • Petrine wields the Flame Lance, the same weapon she wields in Path of Radiance. Like its origin, Flame Lance deals magical damage, at least while Petrine is above 50% HP. It's also effective against Beast units, referencing the fact that fire magic in the Tellius games deal effective damage against beast laguz.
    • Petrine's Threaten Atk/Def is a reference to her Daunt skill in Path of Radiance, which reduces the stats of nearby foes.
  • Oliver's Tome of Favours grants him +5 Atk and Res during combat and heals for 7 HP if his foe is not a Beast. When given its skill refine, Oliver can warp to a space adjacent to a Beast ally that can equip Sing or Dance, and if he's within 3 spaces of said ally, he gets a further +5 Atk and Res. These hilariously bizarre effects all reference a few things:
    • The reliance on having a Beast ally that sings or dances is in reference to his obsession with the Herons and their beauty, who are all classified as Beast units who can refresh with their Sing ability.
    • The HP recovery references the Nosferatu tome he wields, which has a Life Drain effect.
    • The fact that it doesn't work if his foe is a Beast references how he does not want to hurt the Herons, he just wants them for himself to admire. It also references how Muarim, a tiger laguz, scares him in their boss conversation.
    • His ability to warp to a Heron ally could reference his recruitment in Radiant Dawn, where if Rafiel is parked in his range, Oliver will simply ignore everyone else and recruit himself by walking up to Rafiel and talking to him.
  • Ashera wields Colorless Tome, which is earth magic in Heroes, referencing that she has petrified everyone but a few in Radiant Dawn as her judgement to all living things after enough chaos has build up in Tellius.
    • The attack animation of her Order's Sentence is based on the cutscene where she fires a light from the sky and creates a light explosion to petrify everyone not under Yune's protection in Radiant Dawn.
    • Her Order's Restraint gives all her allies within 2 spaces of her +6 Atk/Res and the [Null Panic] status effect, as well as giving herself +6 Atk/Res and the [Null Panic] status effect if there is at least 3 allies within 2 spaces of her at the start of her turn, as well as Order's Sentence giving her Atk equal to the total field stat buff of an ally within 2 spaces of her, references a few thing in Radiant Dawn:
      • The +6 Atk/Res and the [Null Panic] to herself references the Aura she starts with at the final battle.
      • The boost of her Atk references the high Might of all her Judge weapons.
      • The 3 or more allies within 2 spaces of her references 3 Ashera's Chosen Altina, Dheginsea, and Soan, as well as the Thunder, Fire, and Wind Spirits she summons.
      • The [Null Panic] references her obsession with Order, as well as her flat Biorhythim.
  • Volke has Lethality, which allows the user to ignore a huge percentage of the target's Def/Res as well as any non-special percentage-based Damage Reduction skills, referencing his access to Lethality in the Tellius games, which is gained through the Occult Scroll in Path of Radiance, and he joins with it already in Radiant Dawn.
    • Lethality is also exclusive to only dagger units, referencing its status as the Secret Art of the Assassin and Master Ninja classes in the series.
  • Young Boyd's Large War Axe gives him +10 Atk/Spd, neutralizes any debuffs on those stats and deals damage on his first attack equal to 15% of his Atk during combat on odd-numbered turns, but only gives +5 Atk/Spd during combat on even-numbered turns, referencing his Tempest skill in Path of Radiance, where it doubles the Biorhythm bonuses, as well as his Biorhythm with frequent high peaks and low valleys in Radiant Dawn.
  • Fallen Muarim's Wild Tiger Fang has a unique transformation requirement where the user transforms at the start of turns 2 and 4 onwards while also untransforming otherwise, but deals 5 damage to the user if the user attacks if the user transforms, referencing a few things in the Tellius Saga:
    • The transformation references how Feral Ones are Laguz that are forced to transform to become effective fighters, as well as in the chapter "Glory Unwanted" of Radiant Dawn Tormod mentions how Muarim, after being given the Feral elixir by Izuka, Muarim transforms and reverts back when Tormod calls him and the periods between become shorter and shorter.
    • The recoil damage references that in the chapter "Glory Unwanted" of Radiant Dawn Tormod mentions that Laguz becoming Feral drastically shortens their lifespan.
  • Lucia's Queensblade disables nearly every effect possible for both herself and her opponent: neither can activate Specials, take advantage of support or terrain effects, manipulate follow-up attacks (such as guaranteed follow-up attacks or follow-up denial), disable counterattacks, or alter attack priority (like Vantage or Desperation), and neither side can be supported by any skills from nearby allies or foes. All of this is in reference to her Parity skill in Path of Radiance and Radiant Dawn, which negates the effects of skills, terrain, and support bonuses for Lucia and her opponent.
  • Bastian being a Green Tome unit references his high proficiency in Wind magic compared to the other Anima elements, with A rank in Path of Radiance and SS rank in Radiant Dawn.
  • Brave Soren's attire is based on his Arch Sage attire in Radiant Dawn.
    • His Rare Talent allows him to attack twice in one round if he is at 25% HP or above at the start of combat, he has 10 or more Res higher than the foe during combat and either he initiates combat or the foe is a ranged unit, referencing his Adept Skill in the Tellius Saga, where it allows him to attack twice in one round.
    • He has Flare, which either boosts the user's damage by 60% of the foe's Res if the user is at 70% HP or above at the start of combat, or boosts the user damage by 40% of the foe's Res and restores HP equal to 30% of the user's max HP, referencing the Flare skill in the Tellius Saga, where Flare in Path of Radiance was the Occult Skill for Sages and Bishops and halves the foe's Res when it triggers, and in Radiant Dawn was the Class Skill of Archsages, Empresses and Summoners and ignores the foe's Res and restores HP equal to the damage dealt.

    World of Ylisse (Awakening

    • The final map of Tempest Trials: "Dark Clouds Over Awakening" is based on the Premonition and Chapter 23 (both named "Invisible Ties") of Awakening. The same map, albeit modified, is used for Legendary Chrom's and Legendary Male Robin's Legendary Hero Battle maps and Validar's Grand Hero Battle map.
    • The final maps of Tempest Trials: "A Gift of Peace" and Tempest Trials+: "Familiar Faces" are based on Chapter 6 (Foreseer) of Awakening, the former adorned with Christmas decorations, and the latter with Halloween ones.

  • When Heroes first released, the player's first summon would always give a two-star Virion, referencing his very early and rather Medium Aware recruitment in Awakening.
  • In one of Olivia's in-castle conversations, she mentions looking at old souvenirs from a hot spring and a beach, likely referencing the Hot Spring Scramble and Summer Scramble DLC maps from Awakening.
  • Thoron is depicted as a yellow beam of lightning, much like how it was in Awakening.
  • Anna is depicted in Awakening as being obsessed with money. While she's very much an Action Girl in this game, she does seem to have a mild Money Fetish, and several of her special attack lines wouldn't sound out of place for a merchant (e.g. "This one's on the house!" "More than you bargained for?"). She also spends several Paralogues concocting zany schemes to rake in the dough.
  • Nowi, in the Halloween-themed Trick or Defeat banner, is a flying mage styled after a witch. This references both of her reclass options in Awakening: the flying Wyvern Rider class and the magic-wielding Mage class.
    • In addition, one of her character quotes is "You know what? Once upon a time, witches really did exist!"; this references the fact that Ylisse, the world of Awakening, is the same as the world of Archanea and Valentia, but thousands of years after the time of Alm (when witches did indeed exist). Her mobility skills also reference "Warp", signature skill of Witch class.
  • The designs of the Brave Weapons, the Killing Edge and the Armorslayer are taken from Awakening.
  • Fallen and Legendary Robin, instead of a full transformation like other dragon units, merely spawns Grima from behind them to fight, reflecting the Grima battle in the endgame of Awakening.
    • Fallen Male Robin has Grima's Mark on his right hand in his damaged art, referencing that they were chosen to be Grima's vessel due to the amount of genes needed to become the perfect host in Awakening.
    • In Fallen Male Robin's Special art, he has six ethereal wings on his back, referencing in Grima's Dragon form that they have six wings.
    • Legendary Robin is a Legendary Hero of Earth. In The Art of Fire Emblem Awakening, Grima is said to be related to the Earth Dragons (although Retconned to have them be related to the Divine Dragons in Shadows of Valentia), and in Awakening, The Dragon's Table is an altar for Grima where Robin allowed themselves to be possessed via mass sacrifice of Grimleal worshipers, where the Earth Dragons were once sealed.
  • Female Morgan references how tactician units like herself can switch to a wide variety of classes, which reflects the large variety of class change options for both genders of Robin and Morgan. Hers is a Dark Flier, a class available to her in Awakening.
  • Male Morgan is a Red Mage who by default uses the Dark series of magic tomes, ending with the unique Grima's Truth. This is based on how he's a Dark magic using Sorcerer when fought as a boss in the Future Past DLC of Awakening, and though he doesn't use Grima's Truth in said DLC, his grandfather, Validar, does in the main storyline.
  • Branded King Chrom has Sword Valor in his default skill kit, which grants the user and any sword allies up to double SP. In Awakening, the skill Discipline gives the user double weapon experience, which is a Cavalier skill; one that Chrom can reclass into in Awakening, with one of its promotions, the Paladin, being what Branded King Chrom is specifically based on.
  • Walhart has Grani's Shield, which removes his cavalry weakness, referencing a skill exclusive to him in Awakening called "Conquest", where it removes his Beast and Armor weaknesses.
    • Walhart has Luna, referencing that his unique Conqueror class being near identical to the Great Knight class, which he can reclass into and learn that skill.

  • Pegasus Olivia's movement type and character design is based on the Falcon Knight class in Awakening, which she can reclass to.
  • Maribelle is wearing pauldrons and her horse is wearing armor, showing that she is a Valkyrie rather than a Troubadour one from Awakening.
  • Libra's default weapon is Wo Gùn, as he joins with a Killer Axe in Awakening and it closely resembles that game's version of the axe. His exclusive weapon is called Inviolable Axe and looks all but identical to Awakening's version of the Bolt Axe. Its unique refine adds a healing effect that heals him and all allies within 2 spaces for 7 HP after combat, referencing Libra's default War Monk class in Awakening which has access to both axes and (healing) staves.
  • Legendary Lucina is an infantry archer, referencing that she can reclass into the Archer class in Awakening, no matter who her mother is.
    • Legendary Lucina has Future Vision, which allows her and an ally to swap positions and act again once on the same turn. This likely references Olivia, who is one of Lucina's potential mothers and a dancer, and also references a cutscene in Chapter 6 of Awakening where she rescues her father from danger by going in danger first and attacking his assailants.
  • Cherche's Axe is based on the appearance of the axe in her official art, that being the Helswath.
    • The exclusive refinement for Cherche's Axe inflicts the Panic status unto any enemy that is within a cardinal direction of her and has less HP than her, which references her character description in Awakening that notes she's the scariest person in the army when she's angry.
  • Owain wields Missiletainn, a knockoff of Mystletainn, where it is his personal weapon he can potentially gain in Awakening in his recruitment chapter.
    • The pose he strikes before activating a special is based on his Awakening official art, which would be later be referenced in his appearances in other games.

    • In one of her castle quotes, she says she enjoys waterfalls and wants to make a splash, referencing her profile description that she bathes the longest in the army and enjoys swimming.
  • The Tap Battle "Labyrinth of Despair" can be thought of as The Future Past lite. Lucina, Owain (along with Laslow and Selena, a.k.a. Inigo and Severa), and Gerome are all trying to escape the dungeon, while Female Grima and the Morgans are likely the reason the aforementioned three were trapped in the first place.
  • The exclusive refinement for the Robins' Tactical Bolt and Tactical Gale grants +4 Atk/Spd/Def/Res to all allies within 2 spaces of them at the start of their turn, if the number of those allies' movement types is not more than 2, including the Robins.

  • The exclusive refine for Tharja's Hex inflicts -4 Atk/Spd to all enemies within 2 spaces of Tharja, referencing the Anathema skill in Awakening, which inflicts -10 Avoid and Dodge of all enemies within 3 spaces of the user, with even the same icon being used.
  • Panne's Taguel Fang gives her +3 Atk/Spd/Def/Res during combat if the user is not adjacent to a human ally, referencing her hard time trusting other humans, especially those not in the Shepherds, due to them nearly driving the Taguel race to extinction, as well as her pride due to being a Taguel herself.
  • Yarne's Bunny Fang giving him -2 special cooldown after combat if he's at 75% or under, Galeforce to allow him to peform Hit-and-Run Tactics, Atk/Spd Solo, and having Escape Route references his cowardice and self-preservation due to him being the last of his kind, being the last Taguel from the Bad Future in Awakening.
    • Him having Odd Spd Wave references the Level 1 Taguel skill Even Rhythm in Awakening, which gives the user +10 Hit/Avoid during Even numbered turn, the opposite turns that the Odd Wave Skills activate.
    • Him having Galeforce has a bit of irony considering how he's one of the few 2nd gen characters who cannot obtain the skill in any way in his base game. note 
  • Both Panne's Taguel Fang and Yarne's Bunny Fang are effective against cavalry, representing the Taguel's Beastbane skill.
  • Kjelle having Draconic Aura, which boosts the user's damage by 30% of the user's Atk references how she claims to be the strongest of all the children from Awakening.
    • Her wielding the Barrier Lance, which gives her +7 Res if the enemy initiates combat, references how in her recruitement chapter "A Duel Disgraced", she was supposed to fight Cassius, a Sorcerer, alone, and was prepared for it, but was ambushed by a number of Archers due to Cassius not honoring the rules of the duel.
    • In Yarne's C support in the "Spanning Time" Forging Bonds, Kjelle lets him borrow one of her armor suits, named "Argent Lion Mail". This references her A support with Owain, where Owain speaks out loud and names her first armor this while failing to notice she was wearing it.
  • Brady having Atk/Res Push, which if he's at full HP before combat gives him +5 Atk/Res during combat, but loses 1 HP after combat if he attacks, referencing how his attempts to be like other people who are more physical ends with him getting injured in his Supports in Awakening.
  • Nah's weapon being called Oracle's Breath references the ending of "The Future Past" DLC, where she becomes the new voice of Naga (who Tiki now holds the title).
    • Her Oracle's Breath denies any enemy follow-up attacks if she has any field buffs potentially references her support with a non-sibling Female Morgan, where she was training to try and catch swords with her hands due to Wyrmslayers being one of her weaknesses, and which she can learn Swordbreaker if she reclasses into a Wyvern Lord and trains up to Level 15.
  • Cynthia being a Grand Hero Battle unit references her recruitment chapter where she starts as an enemy, due to a criminal tricking her into believing he's Chrom, whom may or may not be her father.
  • Legendary Chrom's attire is based on his Exalt artwork from Fire Emblem Cipher.
    • Chrom wielding a bow is a reference on how he is able to reclass into the Archer line of classes in Awakening, including the Sniper class.

    • In her backpack she has the following weapons in her inventory: Silver Sword, Silver Lance, Killing Edge, Killer Lance, Brave Sword, Longbow, Blessed Bow, Mercurius, Gradivus, and Gáe Bolg, all of them based on their appearance in Awakening instead of their home game. All of them being Swords, Lances and Bows also references how Anna outside of Heroes wields these types of weapons by default, with Swords and Lances in Awakening, and Bows in Fates and Warriors.
    • Anna's accessories are a gold bar and three gold bars, referencing the Medium Bullion and Large Bullion in Awakening, and her Money Fetish she has in the same game.
  • Say'ri has Amatsu, which gives -1 special cooldown and if at the start of combat she is at 50% HP or over, she can counterattack regardless of range, referencing how Amatsu in Awakening has 1~2 range and 5% critical rate.
  • Gangrel wields the Levin Dagger, which gives him +3 Res and if a penalty is inflicted on the foe, he gains +4 Atk/Spd/Def/Res and deal damage equal to 20% of the user's Res during combat, which is a reference to the Levin Sword he wields in Awakening.
  • The unique refine for Sumia's Flower Lance allows her to gain [Canto (2)], which allows her to move 2 spaces after attacking, using an assist skill, or destroying a structure, as well as allow her to warp to an adjacent space of an ally that has 80% HP or lower, referencing in the movie of Chapter 3 of Awakening, she rescues Chrom and moves him away from danger.
  • Fallen Male Morgan and Fallen Female Morgan are from The Future Past DLC from Awakening, where their classes are also matching as well from that DLC, with Fallen Male Morgan being an Infantry Red Mage to match the Sorcerer Class, while Fallen Female Morgan being an Axe Flier to match the Wyvern Lord Class.
    • The design of Fallen Female Morgan's Axe of Despair is based on the Hauteclere's appearance in Awakening, which she also wields in The Future Past DLC.

  • Fallen Rearmed Chrom is based on his appearance as the Risen King in Cipher.
  • Brave Male Robin's Tip the Scales! grants the [Rally Spectrum] status effect to himself and all allies within 2 spaces of him if there is an ally within 2 spaces of him, where [Rally Spectrum] grants +5 Atk/Spd/Def/Res to the user during combat and grants -X special cooldown before the user's first attack, where X = 1 if the user has an effect that either allows the user to attack twice in one round or grants -1 maximum special cooldown, ot otherwise 2, references the Rally Spectrum command in Awakening, where it grants +4 Strength, Magic, Skill, Speed, Luck, Defense and Resistance to all allies within 3 spaces of the user, which can stat with other Rally skills.
    • His Deliverer's Brand allows him to target the lower of the foe's Def or Res during combat if he is at 25% HP or above at the start of combat and he triggers Glowing Ember, Bonfire and Ignis, referencing that he has access to the Ignis skill in Awakening, where it is learned from the Grandmaster Class, which is exclusive to him and his children, where Ignis adds half of his Strength or Magic to his other stat when it triggers, depending on his current weapon.
  • Rearmed Lucina's attire is based on the Great Knight attire in Awakening, which she can reclass into regardless of her mother due to her father Chrom having access to it through the Cavalier line he can reclass into.

    • The final map of Tempest Trials Mini: "Stepping into the New Year" is based on the Endgame (Night Breaks Through) of Conquest, complete with Takumi as the Final Boss and an abridged mix of "End of All (Land)" as the theme music. The same map, albeit modified, and music are used for Fallen Takumi's Grand Hero Battle map.
      • Like in Conquest, there are two Fallen Takumis in his Grand Hero Battle, referencing the flavor text of Skadi creating a simulacrum of the user and how he was paired up with a replica of himself during the final battle.
    • Male Kana's Grand Hero Battle map is based on Paralogue 2 (Dragon Blood) of Fates.
    • Leo and Elise's Bound Hero Battle is based on Chapter 6 (In the White Light/Embrace the Dark) of Fates, although modified to add obstacles which did not exist in the original map.
    • The Paralogue maps of "Festival in Hoshido" is generally based on the Xenologue 21 (Hoshidan Festival of Bond) in Fates, which never saw release in the west, albeit based on a different festival (Heroes celebrating summer, while Fates celebrates Children's Day).

    • Iago's Grand Hero Battle map is based on Chapter 25 (Traitor Revealed) of Birthright. The same map, albeit modified, is also used for Legendary Xander's Legendary Hero Battle map.

    • Kaze & Midori's Bound Hero Battle map is based on Fort Jinya of Chapter 7 (A Vow Upheld) of Birthright and Chapter 8 (Traitor's Brand) of Revelation.
  • The wooden tank in the Counter phase of Mjölnir's Strike is based on the vehicle that the Ballisitcian class uses in the DLC of Fates.
  • Takumi comes with Close Counter, referring to the Point Blank (allows bow units to attack from 1 range) skill he has as an enemy in Conquest and wielding the 1-4 range Skadi as the final boss in the same game.
  • Elise joins with the Gravity(+) staff, as well as later receiving her Elise's Staff later on, which has the same effect as the Gravity+ staff, referencing to the similarly-functioning Freeze staff that she wields when she joins the party in Conquest.
  • Arthur has previously been drawn in Code Name: S.T.E.A.M style for the Fire Emblem Cipher TCG.
  • Jakob has Def 3, referencing how Jakob's Tray gives the user +4 Def when it is equipped.
  • Charlotte getting a bridal variant might be a reference to this card from Fire Emblem Cipher.
  • The Nohrian Summer versions of Xander, Leo, Elise, and Corrin have references to the Fates Beach Brawl DLC in their bios and dialogue. Xander, Leo, and Elise are also wearing their swimsuits from said DLC.
    • Everyone's Summer variant from Fates states that they had a battle to fight over a vacation ticket with the help of their retainers, referencing the Beach Brawl DLC in Fates where all of the royal siblings fight with their retainers to earn the the ticket Corrin refuses to use to go on a vacation.
      • Interestingly, Summer Corrin being available is due to her reluctantly accepting the ticket to go on vacation when everyone else refuses, as she states in one of her quotes.
    • Summer Takumi being happy and excited when being at the beach references when he wins the Beach Brawl DLC battle, where his retainers correct him that he really want to go to the beach despite his insistence, and a photo of him shows him enjoying his time with a big smile, to the point that his retainers thinks that it is such out of character of him that they think that the Takumi in the photo is a fake.
  • Selena, Odin and Laslow all reveal their true identities in their level 40 conversations, much like how they would if you bonded with them enough in their platonic skinship scenes.
  • Azura's Performing Arts variant is her in her disguise from the Conquest version of the Cyrkensia dance.
    • Her voice having a deeper tone than her regular variant references the Dark Song cutscene in Conquest where she sings in a deeper voice to disguise herself.
  • Male Corrin's default special skill is Dragon Fang, a skill that he can learn by default in Fates and referencing the fact that he is half dragon. The same applies to his female counterpart, who has Draconic Aura, her summer counterpart, who also has Dragon Fang, and for Male and Female Kana, who have Dragon Fang and Draconic Aura, respectively. Likewise, Camilla possesses Draconic Aura, referencing the draconic lineage of the Nohrian royal family.
    • In all of the special arts of both original Corrins and both Kanas, their dragon tail can be seen. In Fates, whenever Dragon Fang is triggered when in their default class while using a sword, they transform some of their body parts into dragon ones to boost their attack.
  • The designs of the Iron, Steel and Silver weapons are taken from Fates, as are the design of the basic tomes. Gunter's Inveterate Axe and Charlotte's Fair-Fury Axe were actually modified from the Silver Axe design.
  • Three of the four Children of Fate characters (Soleil, Siegbert, and Rhajat), as well as all the ones from the Wings of Fate characters (Female Kana, Male Kana, and Shigure) say "It's good to meet you." upon being summoned*. At the end of the Heirs of Fate DLC story arc in Fates, all of the children characters promise to use that exact phrase as a Trust Password in case they were to ever meet again.
    • With the exception of both Kanas, Selkie and Velouria, all of the children say their names out loud when selected. In Fates their connected parent have voicelines where they say their name.
    • The Nohr children with their default skill kits usually encourage an aggressive playstyle, while the Hoshido children encouraging a defensive playstyle with theirs (including Shigure and both Kanas), most prominent with Siegbert and Shiro, respectively. This references that the conflict began in Fates with Nohr invading Hoshido, with Hoshido on the defensive at the beginning of the war.
  • The beginning of Tempest Trials Mini: "Stepping into the New Year" has Azura mention wielding a pine branch, an actual weapon that can be used in Fates.
  • Fallen Takumi has Skadi, which at the start of turn 3, deals 10 damage and the panic status to all enemies within the 3 columns he is centered in, referencing his infamous attack in Conquest where every 3 turns (2 on Lunatic) he halves the HP of all ally units on the map not hiding behind barriers summoned by dragon veins. Interestingly, the tactic to avoid this Area of Effect in Heroes (go outside his affected columns) is the opposite of how to avoid it in Fates (hide behind barriers summoned by dragon veins on top of him).
  • Both Kanas have Water Breath, which references their connection to their grandfather, who has control over water. The animation of Water Breath is also based on the Torrential Roar, Corrin's Final Smash in Super Smash Bros..
    • Female Kana has red string bindings attached to her leggings, similar to those seen on characters on the Hoshidan side such as Sakura and Takumi. In other Fire Emblem spinoff material, such as Fire Emblem Warriors and Fire Emblem Cipher, as well on the cover of Birthright, Male Corrin, who is Female Kana's father, is seen on the side of Hoshido. Her Sun Dragonstone is also a reference to this, since in Fates there is a lot of sunlight in Hoshido, and need of this to grow their crops is one of the reasons why Nohr is declaring war on Hoshido.
  • Hinoka's Spear grants her +4 Atk/Spd whenever an Infantry or Flying unit is within 2 spaces of her. This is in reference that out of all Hoshidan units in Fates, there is no Cavalry (not including the Mechanist) or Armored units on the Hoshido side, while all of her siblings all start as infantry classes, can end in infantry classes, or reclass to flying classes.
    • The exclusive refinement for Hinoka's Spear grants her Flying and Infantry allies within 2 spaces to move to adjacent space of her. This references the Rescue staff in Fates, which she can use as a Falcon Knight immediately due to the Rescue staff requiring only an E rank to use.
    • Hinoka's Kinshi variant's Warrior Princess bow has gives her allies within 2 spaces +3 Atk during combat, referencing "Rallying Cry" her personal skill in Fates, which grants all allies within 2 spaces +2 damage given.
  • Camilla's Axe grants her +4 Atk/Spd whenever a Cavalry or Flying unit is within 2 spaces of her. This references the exclusivity of Cavalry units on the Nohr side in Fates, as well as having all her siblings being Cavalry units in Fates, and with her retainers Beruka being a Flying unit and Selena being a Bow Knight in Camilla's last battle in Birthright.
    • The exclusive refinement for Camilla's Axe gives her allies +3 Atk/Spd within 2 spaces of her if they are Cavalry or Flying. This is reference to her personal skill Rose's Thorns which gives her adjacent allies +3 damage given and -1 damage taken, with the same icon used for this specific refinement.
  • With the 2.5.0 release of Heroes, Takumi is one of you first allies you recruit at the very beginning of the game. In Fates, Takumi is the very first ally in the game, in the Prologue Ties That Bind in all the routes. Fitting, he plays the same role in this case (being your first ranged attack unit).
  • Male Corrin's refined Yato give him +2 in all his stats, which is exactly the stat boost given from the Alpha Yato in Revelation.
    • The exclusive refinement for Yato gives a support partner within 2 spaces of him +4 in all their stats. This is referencing the personal skill Supportive, which gives a lead unit in an Attack or Guard Stance stat boosts if they have at least a C support rank with Corrin, and having the same icon used from Fates.
  • Legendary Ryoma is a Legendary Hero of Water. This is due to his strong relationship with his adoptive mother and sibling, as well as Azura, a potential marriage partner, who are from Valla, which is heavily associated with water.
    • Alternatively, he was given water status due to his weapon the Raijinto, named after the Japanese god of lightning and storms.
      • Along with his Ascended Meme armor resembling a lobster, a creature that lives in water.
    • Legendary Ryoma's signature B skill is "Bushido" (+10 damage on special activation), which is his personal skill in Fates, which grants him +2/-2 damage dealt/taken and +10 critical hit rate if he's a level higher or equal to the supported ally.
    • Bushido II always grants him +7 damage, referencing the skill "Swordfaire", which boosts his damage as long as he is wielding a sword (his only weapon as a Swordmaster).
    • Ryoma is riding a Kinshi, like his sister Wings of Fate Hinoka, as well as wearing similar armor. In Fates, he can reclass to a Kinshi Knight.
    • The unique refine for Raijinto grants him +4 to all stats if he is within 2 spaces of an ally, which mirrors the effects of Bushido in Fates (as mentioned above). The alternate condition is if the unit initiates combat, referencing the skill "Duelist’s Blow" (increases evasion if unit initiates combat) learned by the Samurai class in Fates.
  • The unique refine for Siegfried inflicts Atk/Def-5 on foe during combat if the foe's HP is 75% or more, referencing Xander's personal skill "Chivalry" in Fates, which grants him +2/-2 damage dealt/taken if the foe has full health.
  • In the castle, Summer Camilla happily talks about the sunlight and wishes that everyone in Nohr could experience it. In Fates, the sun rarely shines in Nohr due to constant amounts of cloud cover and storms, and as a result crop yields are poor.
  • Silas having Reposition and Steady Stance references the Shelter skill in Fates, where the user targets a friendly unit to pair up with the user, forcing a Guard Stance.
    • The unique refine for his Sworn Lance allows him to gain +7 Atk/Def during combat and deny any of the foe's follow-up attacks if either he is within 3 spaces of his support ally or his support ally is at 80% HP or under at the start of combat, referencing his personal skill "Vow of Friendship" in Fates, where it allows him to deal 3 more damage and receive 3 less damage if Corrin is his ally on the map and Corrin is at half HP or under.
  • Ophelia's Missiletainn grants her -1 special cooldown for every tome user on her team, referencing her personal skill Bibliophile, which gives her +10 critical if she has 3 or more tomes in her inventory, even if she's not a class that can use tomes.
    • Her being a blue tome user instead of red one like most Dark Mages/Shamans in Heroes, references both that her Missiletainn tome having an ice attack animation, and that Nohrian Dark Mages wield tomes in general, rather than dark magic specifically. This can also be seen with her father Odin, who is also a blue tome user due to being commonly associated with the thunder element.
  • Nina joins with the Shining Bow as it is easily acquired from her Paralogue in Fates. It dealing 7 extra damage if the opponent's Def is 5+ higher than their Res references that it deals magical damage in Fates.
    • One of the effects of Nina's Spy-Song Bow is that she would receive +6 to all stats during combat if she is within 3 spaces of two allied units supporting each other (excluding herself), referencing her personal skill "Daydream" in Fates, which grants her +2/-2 damage dealt/taken if she is standing next to two male allies in Guard Stance.
  • Flora's Atk/Res Solo skill references that she was alone at the start of the Birthright chapter map "Lost in the Ice".
  • Garon being a Red Manakete references his appearance at the end of Birthright, where he appears as a Blight Dragon, and the red color due to his connection to darkness.
    • Him being an Infantry unit rather than an Armored one is referencing that he has 6 Movement rather than 5 like all Generals in Fates while he is in his dragon form.
    • His Breath of Blight effect, being that any enemies within 3 spaces at the start of turn 4 takes 10 damage and heals 5 HP for every enemy hit by this attack unrefined and within 4 spaces at the start of turns 3 and 4 takes 13 damage and heals 13 HP for every enemy hit by this attack refined references the dragon veins he starts next to in "Dawn Breaks", where on a specific quarter of the map he creates a blight area which drains HP from any player units within that area while also healing him. Interestingly, the area of effect is inverted than how it occurs in Fates.
    • His breath weapon also removes his dragon weakness, referencing that the Blight Dragon has no weaknesses in Fates, as the only dragon-slaying weapons in that game do not affect him.
  • Halloween Kagero's outfit is based on the Maid class in Fates, which she can reclass into if she's Jakob's wife or the male Avatar's if he has the Troubadour as his second class, albeit with the Partner Seal.
    • Her weapon, Bottled Juice, is based on the Bottle weapon in Fates, although it is a sword in its home game, while it is a dagger in Heroes. The -1 special charge buildup for enemies also references the Bottle's effect of granting +10 critical avoid.
  • Both Adrift Corrins and Mikoto are seen wearing near-identical attire to that of regular Azura, referencing that they are actually from Valla.
  • Mikoto has Martyr as her healing support skill, referencing her sacrifice to save her child from her possessed husband in Chapter 5 (Mother) of Fates.
  • Adrift Azura being young is inspired by her appearance in the "Revelation Anthology" comic, where it showed how she'd look like around the time she was still in Nohr.
    • Adrift Camilla is based on a conversation between Azura and Camilla in one of the Festival Bond DLC events that wasn't released in the US. In it, Azura reflects that she saw a very lonely young girl in one of Nohr's festivities and always longed to make friends with them so she could experience an older sister.
  • The "Kingdom of Hoshido" Tap Battle is one big Call-Back to the invasion of Hoshido, complete with the Hoshidan royals (barring Ryoma) fighting alongside their retainers, a couple of pre-battle quotes being borrowed from Conquest, and even Fallen Takumi as Extra Stage 1's boss succeeding Ryoma as floor 100's boss.

    Misc. 
  • Líf's Mythic Hero Battle map features a Lance Fighter with Spd/Def Bond and Dull Close, and an Axe Fighter with Astra and Escape Route. These two represent Sharena and Anna respectively, as the two have similar skills in their loadouts note . The blue mage cav has Vantage, which could represent Bruno, whose Valaskjalf tome has Vantage built in, and he's also a blue mage cav.
  • The final map of Tempest Trials+: "Chaos Named" is based on Chapter 5 (Mother) from Fates, albeit not in ruins. The name of the Tempest Trials+ itself, however, is that of the fourth part of the Paralogue of Radiant Dawn. In addition, it is implied that "Micaiah" whom the player fights as a boss is actually Yune who somehow took Micaiah's form to join in the festivites.
  • The player is represented as a faceless tactician who is the commander of their forces. This has been done twice before, once in The Blazing Blade and again in Awakening. The player character is much like Eliwood's faceless tactician in The Blazing Blade; they didn't show up very much, but they were responsible for the coordinated tactics the player army pulls off. However, they had little importance in the story. In Awakening, Robin was a customizable unit who acts as a tactician who was important to the story, not least because of the strategies they provided helping the Shepherds. Here, the player character takes on features of both, being faceless and only counting as the tactician to the order of heroes, but having more story importance and actual presence within the world. Even the tactician's hooded design is a recolored design from characters of past titles, particularly Robin from Awakening and Sumeragi in his "hooded assassin" outfit as well as Anankos' human form from Fates.
  • One of Roy's voiced lines is "For those I must protect, I cannot lose!" This is more-or-less a direct translation of one of his victory lines from the Super Smash Bros. series.
  • The original Brave Heroes in the English version have an extra line that references a game they appeared in. Ike and Roy reference their crowd cheers from Super Smash Bros. while Lyn and Lucina use quotes from their game.
    • With the exception of Roy, the original Brave Heroes all use their secondary weapon types from their original games — Lucina uses a lance, Lyn uses a bow, and Ike uses an axe.
    • Additionally, Brave Lucina and Brave Ike were drawn by the artists of their original games, those artists being Kozaki Yusuke and Kita Senri, respectively. The same applies to the second set of Brave Heroes as well (barring Hector, drawn by Kita Senri instead of Kaneda Eiji or Wada Sachiko). Brave Celica's art was done by Hidari, Brave Ephraim's art was by Wada Sachiko, and Brave Veronica's art was (naturally) by Kozaki Yusuke.
  • Brave Veronica has a line where she tells the Summoner that on the back on a horse, one can see far into the distance and she offers a ride. This is exactly what she got from Xander in the manga.
  • This image commemorating the eventual release of Super Smash Bros. Ultimate is chock-full of mythology gags. Near the top-left are Lucina and Chrom re-enacting the poses they strike on the box art of Awakening, while Female Robin prepares to cast a spell, just like how she charges her neutral special. Near the top-right, Marth is performing his up taunt where he points his Falchion towards the sky, with Adult Tiki standing near him as a reference to their bond in the Archanea games. Below them are Ike and the Black Knight squaring off as they did in Path of Radiance, while Lyn and Roy are to their left, Lyn being near Roy being a nod to how she can marry Eliwood in The Blazing Blade and become Roy's mother. Meanwhile, Male Corrin has taken center stage and has launched Feh (who is wearing a happy expression) into the air, just like how fighters in Ultimate launch their opponents. All this commotion takes place on the Fire Emblem-themed stage Castle Siege, while a Fake Smash Ball hovers above, which likely refers to how the image itself is (clearly) not a real screenshot of Ultimate.
  • All of the Null skills have an eye in their icon, referencing the icon of the Nihil Skill in most of the games in that have this skill, which negates enemy battle skills.
  • Naga is listed as being from Mystery of the Emblem and Awakening, as she has made an appearance in both of the games.

    • Her skill Divine Fang at the start of her turn grants all adjacent allies "effective against dragons", referencing that she gave humans ways to defeat dragons in her absence, such as the Falchions and the Book of Naga.
    • She is the Mythic Hero of Astra, which is near to the Heaven affinity in the main games, referencing that she has gone to the heavens after Medeus' first defeat.
      • Her giving the Def bonus references that she was humanity's defender against the other dragon tribes when they rebelled against humanity.
  • The Disarm Trap being limited to only Dagger units references that Thieves in most games can disarm traps if they stop on a trap tile, most notably in the GBA games and Fates, where in the latter in Chapter 17 (Den of Betrayal) of Conquest, any friendly unit who has Locktouch, one of the skills of Ninjas and Thieves, stops on top of the caltrop traps disarms and removes them, the main example being the Ally Saizo in that chapter.

    • Cordelia's Lance is based on Cordelia's personal weapon in Fire Emblem Warriors.
    • The attack animation for Elise's Staff comes from her Awakening Special in Fire Emblem Warriors.
    • Young Caeda and Harmonic Caeda and Plumeria having multiple effective traits are based in Caeda being able to have 3 effective traits (one more than other characters) on her Wing Spear in Fire Emblem Warriors.
  • Tokyo Mirage Sessions ♯FE:
    • The Session Skills, which the value depends on the amount of player or enemy units that moved before the one that attacks reference the Session Skills in Tokyo Mirage Sessions #FE, where attack Session skills allow the user to perform that attack if one of the main cast did a weakness attack on the opponent, in which another allies can follow up with one with one of their Session skills if the previous Session skill match the activation requirement, even if it didn't hit a weakness.
    • In one of her voiced lines, Tsubasa tells the player that if a cat doesn't want to be pet, you should just talk to it, followed by a meow. In her second side-story, when her director told her that she lacks "devilish charm", she decides to find out what that means by seeking out a stray cat named "Little Devil". When trying to pet him leads to hissing, she decided to instead communicate to him via meowing.
  • Harmonic Pirate Veronica is paired with Xander, who is dressed up as a pirate for the Halloween-esque Nohrian Festival of Bonds DLC in Fates, which also never saw release in the west.
  • The "Rock 'n' Roll!" Grandmaster Tactics Drill is based off of the FEH A Day in the Life manga chapter where Azura is seen performing for Reinhardt (namely his sword variant), Fallen Hardin, and Michalis. The same four units are used in the Tactics Drill, albeit regular Azura rather than Performing Arts Azura, and as a nice touch, Azura and Reinhardt both have the sunglasses accessory equipped.
  • Spring Severa's Gullinkambi Egg has an effect where if either she or an ally has entered combat once that turn, she can strike twice. Severa is also in Fates under the identity Selena, and this may be a reference to her personal skill in Fates, Fierce Rival. Fierce Rival is also dependent on an ally having acted in combat first, where if they strike a critical hit and Selena is supporting her ally in Attack Stance, she will also score a critical hit.
  • In the Weave of Fate Forging Bond, Sothis awakes from a dream where she tells Byleth to join Smash, referencing Byleth's reveal trailer in Super Smash Bros. Ultimate where she does the same.
  • The Sage of Khadein banner all feature mages and magic wielders, who can all acquire a status that lets them travel through terrain unimpeded. This is in reference to the fact that in games with desert maps, most units are slowed down and suffer a Mov penalty except for mages.
