* Knocking heads with the '''E.M.M.I.''' from ''VideoGame/MetroidDread'' is an exercise in absolute frustration, especially for an Ace level battle. For starters, it's a stamina battle against a Giant R.O.B.; nothing necessarily wrong is there with that. Second, it gets increased move speed; still not a call for concern just yet. Then you see it periodically becomes invincible. There we go, ''now'' we have a problem. Then when you see the stats, you'll notice you have only 30 HP on you. Don't be fooled by it having only 20 HP by comparison; R.O.B. rapidly regains its invincibility, leaving you with only 1 or 2 seconds to actually hit it with anything at all. Combined with its high speed and tendency to grab you much like what the E.M.M.I. does in its home game, and it can quickly make short work of you even with your best spirit teams and battle items. Even worse, this is one spirit fight where you can't really cheap shot it due to it being near constantly invincible, with its times for vulnerability also being inconsistent once R.O.B. stops being invulnerable. And certain attacks with it ''can't work at all'' because of how slow they can be to work in this battle. Hope you enjoy the horror sounding track that plays with it, because you might be hearing it a lot here. Want a good score on the Spirit List rematch? Better have a stockpile of 50% Damages and [[LuckBasedMission a lot of luck]], especially if you foolishly think you can beat this fight without a spirit helping you out.

* '''The 13 Sentinel Pilots''' are truly a nightmare. To begin with, it's a timed Stamina battle against thirteen Giant R.O.B.s. Then, you realize that some of them come equipped with a Super Scope, some have the Impact Run ability, and some get a Sudden Final Smash upon arrival ([[GuideDangIt Too bad the game only tells you about that last one]]). Add that to the R.O.B.s' usual rage-inducing moves like the Gyro attack, its down flurry attack where it's constantly hitting you with its arms at a downward angle and its Up-Smash being even more damaging than usual thanks to their Giant size, and you'll more than likely have a good chunk of your Stamina lost by the time you get through the first wave of R.O.B.s. Oh yeah, did we mention you only have 100HP without Stamina enhancing Spirits?

With the two DLC waves introduced to us by December 12, 2018 (made official by April 17, 2019 and completed by October 18, 2021), each character introduced to this game also has their own special Spirit Board filled up with at least eight different spirits from their series (or multiple series' in the case of Terry Bogard) fully available for you to go up against. Unlike the regular Spirit Board, you can go up against these spirits as many times as you need to... which is a good thing since some of these spirits can be just as challenging as the spirits implemented into the game by default.

* '''[[VideoGame/PrincessPeachShowtime Peach and Stella]]''' are more than capable of stopping your show in its tracks. For starters, it's a fight against Peach and a miniature yellow Kirby representing Stella on Luigi's Mansion. Peach prefers using Up-Smashes, so knowing that, you can be prepared for her maneuvers. Unfortunately, Kirby tends to be pretty aggressive, attacking you while you're attempting to land a combo on Peach, and their small size makes it hard to land a hit on him. Worse, representing Peach's transformations, the Lyn, Chef Kawasaki, and Akira Assist Trophies will spawn to assist the pair. Now, here is where Kirby's aggressiveness can get ''really'' annoying, as it will get in the way of you trying to take out Lyn before she can land her Critical Hit on you as well knocking you into range for Kawasaki to catch you and put you in his pot. By the time Akira appears, your damage percentage will most likely be at the point where one good hit from him and the curtain's going to fall on your performance.

By the time Akira appears, your damage percentage will most likely be at the point where one good hit from him and the curtain's going to fall on your performance.

* On that note, '''Koraidon and Miraidon''' themselves. The two are represented by Charizard and Meta-Ridley on Final Destination. The floor is electrified, meaning since Final Destination doesn't have any platforms to avoid it, you're going to need to fill two Support Spirit slots with an appropriate Spirit in order to ''just be able to fight''! The two also work extremely well in tandem, meaning your attempts to land a combo on one will often be interrupted by the other landing a Flamethrower/Plasma Breath or one of the aerial attacks both prefer using on you. The best way to defeat them may be tricking the two into launching a Flare Blitz/Space Pirate Rush off the stage until they're too far away to fly back onto the stage, but with how far/high their respective up-specials can get them to travel, even ''that's'' no sure thing.

* '''The 13 Sentinel Pilots''' are truly a nightmare. To begin with, it's a timed Stamina battle against thirteen Giant R.O.B.s. Then, you realize that some of them come equipped with a Super Scope, some have the Impact Run ability, and some get a Sudden Final Smash upon arrival ([[GuideDangIt Too bad the game only tells you about that last one]]). Add that to the R.O.B.s' usual rage-inducing moves like the Gyro attack, its down flurry attack where it's constantly hitting you with its arms at a downward angle and its Up-Smash being even more damaging than usual thanks to their Giant size, and you'll more than likely have a good chunk of your Stamina lost by the time you get through the first wave of R.O.B.s.

* '''Terapagos''' may only be an Ace, but it feels much more difficult than the same event's Legend-level spirit battle, Koraidon & Miraidon. You fight three Squirtles in a row on Fountain of Dreams; the first Squirtle is just a regular one, but the second is giant and metal, and the third is giant, gold, has a quickly-charging Final Smash meter, and instantly gets a Final Smash after taking some damage. The latter two Squirtles have increased strength and durability due to being giant and metal/gold while also keeping Squirtle's speed and mobility, turning them into tanky {{Lightning Bruiser}}s. Even if you quickly KO the first two Squirtles without taking much damage, the third Squirtle loves to throw you off-stage, hit you with a Triple Finish, and then follow up with a Water Gun just to make sure you can't get back on-stage.

* Just when you thought things were finally over and done with, the January 14, 2022 Spirit Board update gave fans one more (last?) unexpected update in store. To celebrate Street Fighter's 35th anniversary, the game added '''Evil Ryu''' as a Spirit, and if you ever played the VideoGame/StreetFighterAlpha series, you'll know that you're going to have to prepare for a world of hurt with him. As a sort of sequel to the Akuma spirit fight (which makes sense, considering what causes Evil Ryu to happen in the first place), you must defeat a viciously aggressive, black colored Ryu (representing his evil side coming out) that has increased Special Power and increased overall Attack Power on the Omega Suzuki Castle stage. The good news is that your defense isn't dropped, which means it is not as much of a case of RocketTagGameplay as Akuma has. There are two new problems to compensate that, however: #1, Evil Ryu has a Neutral affinity, so you are not allowed to have a TacticalRockPaperScissors color advantage to give you an edge, unlike Akuma, who has a Red/Attack affinity and can at least be more easily dealt with via a Blue/Shield Primary. The second, more glaring problem is his '''Sudden Final Smashes'''. Said Final Smashes are given to him almost every ten to fifteen seconds, and he ''will'' chain them into his already deadly combos so you can't escape from them. Despite it being a Stamina Battle, Evil Ryu is also more than willing to fight dirty by first trying to knock you off stage, then using his ranged Final Smash (Shinku Hadoken) as an unavoidable edgeguard, thus sucking you in before dragging and knocking you into the Blast Zone for an early kill. Even with your best Spirit teams on hand, this Satsui-No-Hado-fueled monster of a Spirit has three words for you: PrepareToDie.

* '''The 13 Sentinel Pilots''' are truly a nightmare. To begin with, it's a timed Stamina battle against thirteen Giant R.O.B.s. Then, you realize that some of them come equipped with a Super Scoper, some have the Impact Run ability, and some get a Sudden Final Smash upon arrival ([[GuideDangIt Too bad the game only tells you about that last one]]). Add that to the R.O.B.s' usual rage-inducing moves like the Gyro attack, its down flurry attack where it's constantly hitting you with its arms at a downward angle and its Up-Smash being even more damaging than usual thanks to their Giant size, and you'll more than likely have a good chunk of your Stamina lost by the time you get through the first wave of R.O.B.s.

* '''VideoGame/{{Rayman}}''' may not seem overly threatening at a glance, but the battle has the right combination of elements to make it quite the trial. You engage in a stamina battle in the Battlefield form of The Great Cave Offensive against Sonic, whose incredible speed makes him hard to keep up with and lets him get in your face instantly, and his strength is boosted, so it hurts a lot when he hits you. What takes the fight into the realm of frustrating is that a Sukapon Assist Trophy ([[FloatingLimbs the actual Rayman stand-in]]) will also be attacking you. Trying to drain Sonic's health becomes a nightmare when Sukapon can launch heads at you from a great distance to interrupt your attacks and deal a ton of damage, or throw you away if you get too close. Worst of all, the AI has an uncanny ability to juggle you between the two fighters' attacks, swiftly racking up the damage and making it nigh-impossible to get a hit in. Fortunately, like with most fights with assists, if you manage to defeat Sukapon (which is not as hard, as Sukapon may be strong, but she is not too durable), the fight becomes far more manageable.

* '''[[VideoGame/Pikmin1 Emperor Bulblax]]''' pushes the fairness of Stamina Battles to its absolute limits. Being on Distant Planet Omega Form, the battle is mano a mano between you and a Giant King K. Rool. The kicker? He both has [[MadeOfIron Super Armor]] ''and'' is highly aggressive. This nasty combination ends up countering all three forms of strategy, as Grab is nullified by him being Giant, Attack is nullified by Super Armor, and Defense (his weakness) is nullified by his active aggression. It's made even worse with him having more HP than the player, as well as getting his Final Smash Meter up quicker than you. The only feasible form of countering him is through items, but almost all of them don't have a long-term form of beating him and only serve to be minor impediments. It's especially jarring when the island he's found on is filled with Spirits that are either easy or at least manageable, making this a blatant form of SurpriseDifficulty.

* As if one annoying Kapp'n battle wasn't bad enough, let's try the vanilla '''Kapp'n'''. It's you versus Iggy on Wuhu Island locked on the "rocks at sea" section. The rules are "Buoyancy reduced" and "Hazard: heavy wind". This means that you die within seconds of touching the water and (unless you have a Spirit to cancel the effect - which if you've only acquired Spirits from World of Light, you ''don't'' at this point) have to struggle just to move around the stage. Meanwhile, Iggy is completely unaffected by the wind and bounces around the stage, hitting you from every angle and gleefully jumping out of the way of your attacks. The frustration induced by this fight is far beyond what its 9,600 rating would imply - and it's ''required'' that you do this fight because you need Kapp'n to travel over water and reach the airport island.

* From Sephiroth's board, '''The Turks and Rufus Shinra''' is an Ace spirit that will send you into the Lifestream. It's similar to both the Phantom Thieves of Hearts and the Hero's Comrades in that you're facing a large number of fighters who are all too willing to GangUpOnTheHuman, in this case multiple Mii Brawlers and Swordfighters. Explosive items also spawn very frequently, meaning you can often end up taking unavoidable damage as a Bob-omb or Smart Bomb lands right in the path of one of your attacks. Your target, a Robin representing Rufus himself, doesn't spawn until all other fighters are defeated, by which point you're likely to be damaged enough that even his Wind jab combo can easily pick you off. All while you're praying an explosive doesn't drop on your head at the worst possible time.

* As for the second Legend battle, the '''Pneuma''' spirit battle is a stamina match against Pyra & Mythra and a Shulk representing Rex on Cloud Sea of Alrest. Shulk is a major pain in the rear, often interrupting your attacks and catching you by surprise, but he at least has (relatively) low HP. Pyra & Mythra gain sudden Final Smashes ''at almost every minute''. If that wasn't enough, when Pyra & Mythra are at high damage, their movement speed is increased (with Mythra already being quite fast) and they will turn metal (the game states that the transformation is occasional, but [[TheComputerIsALyingBastard it's actually permanent]]). A support spirit that heals you when you are at high damage is a ''must'' for this fight, otherwise you'll get absolutely obliterated between Shulk and the Aegis' combo game and all the Final Smashes.

* '''VideoGame/{{Rayman}}''' may not seem overly threatening at a glance, but the battle has the right combination of elements to make it quite the trial. You engage in a stamina battle in the Battlefield form of The Great Cave Offensive against Sonic, whose incredible speed makes him hard to keep up with and lets him get in your face instantly, and his strength is boosted, so it hurts a lot when he hits you. What takes the fight into the realm of frustrating is that a Sukapon Assist Trophy ([[RaymanianLimbs the actual Rayman stand-in]]) will also be attacking you. Trying to drain Sonic's health becomes a nightmare when Sukapon can launch heads at you from a great distance to interrupt your attacks and deal a ton of damage, or throw you away if you get too close. Worst of all, the AI has an uncanny ability to juggle you between the two fighters' attacks, swiftly racking up the damage and making it nigh-impossible to get a hit in. Fortunately, like with most fights with assists, if you manage to defeat Sukapon (which is not as hard, as Sukapon may be strong, but she is not too durable), the fight becomes far more manageable.

* '''[[VideoGame/YoshisWoollyWorld Yarn Yoshi]]''' is a surprisingly irritating battle, despite its simplicity. You're set against four Yoshis on the Super Happy Tree map, with the only battle modifier being that all fighters are much easier to launch. The trouble is that these Yoshis are *viciously* aggressive and intelligent, and are quite fond of smacking you straight out of bounds with one perfectly-timed smash if you try to flee them ganging up on you. With many characters, it's difficult to even get a good strike in one of the Yoshis without the others interrupting and rapidly building up your damage. Combined with the relatively narrow arena that leaves little room for navigation, and it's a recipe for disaster.
* '''Geno''''s battle will leave you praying to the Star Road. This match sets you against five [=CPUs=] who each represent one of the five party members from ''VideoGame/SuperMarioRPG'' in the Battlefield form of Mario Galaxy in a 2:30 timed match. The opponents come in the order of a Mario who begins with a Koopa Shell, an unchanged Bowser, a slightly larger Kirby standing in for Mallow, a Peach with autoheal, and a Sheik with a Super Scope as Geno, all of whom are competent enough to completely obliterate you if you let them surround you. While you only need to defeat Sheik to complete the battle, [[MarathonLevel she doesn't spawn in until after the second enemy dies]], so the rest of the team has plenty of time to wear you down if the timer doesn't do that for you already.

* '''Great Fairy''' takes the form of a Zelda that is both Giant and has Increased FS Gain, which is a mean enough combo in its own. But then she ramps it up and adds two more skills to the mix: the first is increased Special power, which makes the already hard-hitting and hard-to-dodge Giant hit even harder. The second and even worse skill is ''Critical Health Recovery'', which means she heals 100% damage when she reaches 100% damage. Unless you KO her with the blow that triggers the heal, not only will she recover from your hard work (and it ''is'' hard work, as her Spirit Power is 9,500), but because of Increased FS Gain, she will likely have her Final Smash ready when she does. Not helping matters is that Zelda has a Danger Zone-style Final Smash (Triforce of Wisdom) that has a ridiculous range because she is Giant, and with the beating you're likely to take from her Special spam, along with her Final Smash being a OneHitKill when you're above 100%, this ''will'' KO you (and even if you aren't at 100% damage, chances are real good that depending on where she used it she'll kill you from the move's launching power anyways). As if Zelda's range wasn't enough of a problem on its own, this fight takes place in Fountain of Dreams, which is far from being a spacious stage.

* The conditions for '''Hinawa''''s spirit battle, which takes place on Yoshi's Island, may look simple (all the fighters being easy to launch), but don't let that fool you. Zelda, who represents Hinawa of course, has a wide range of attacks that can hit you from distance, mainly Din's Fire and Phantom Slash. If that wasn't enough, she is aided by two Lucas fighters, who represent Lucas himself and his twin brother Claus, who gang up on you alongside Zelda and constantly spam PK Fire, PK Freeze and PK Thunder. Remember what we said about everyone being easy to launch? Yeah, you better have chosen a heavyweight fighter for this fight because lightweight characters like Pichu or Kirby have little to no chances with this one. Oh, and by the way, this spirit battle is one of the two spirits [[BeefGate that can be mandatory to defeat in order to reach]] the FinalBoss of World of Light.

* '''The Able Sisters''' spirit battle takes place on Town & City and pits against three Sonics whose sole purpose seems to be [[GangUpOnTheHuman ganging up on you]]. If you aren't careful, you are highly likely to get stuck in their nasty combo attacks. They also start the battle with a drill each, and if the drill catches you it is also highly likely that it'll take you to the blast line, [[OneHitKill instantly KOing you]]. This battle is near-to-almost impossible without using any spirits.

* '''Yarn Yoshi''' is a surprisingly irritating battle, despite its simplicity. You're set against four Yoshis on the Super Happy Tree map, with the only battle modifier being that all fighters are much easier to launch. The trouble is that these Yoshis are *viciously* aggressive and intelligent, and are quite fond of smacking you straight out of bounds with one perfectly-timed smash if you try to flee them ganging up on you. With many characters, it's difficult to even get a good strike in one of the Yoshis without the others interrupting and rapidly building up your damage. Combined with the relatively narrow arena that leaves little room for navigation, and it's a recipe for disaster.

-->-- [[https://www.youtube.com/watch?v=XGZPaX8aHZY Parody lyrics]] for "Jump Up, Super Star!" based on how absurdly difficult Pauline's Spirit Battle is.

* '''Great Fairy''' takes the form of a Zelda that is both Giant and has Increased FS Gain, which is a mean enough combo in its own. But then she ramps it up and adds two more skills to the mix: the first is increased Special power, which makes the already hard-hitting and hard-to-dodge Giant hit even harder.

As if Zelda's range wasn't enough of a problem on it's on own, this fight takes place in Fountain of Dreams, which is far from being a spacious stage.
* Don't let '''Kapp'n ([[VideoGame/AnimalCrossingWildWorld Wild World]])''' fool you just because he is an Advanced spirit. You face off against Luigi in a stamina battle taking place in New Donk City Hall. The main problem surrounding this fight is that the Kapp'n Assist Trophy appears, meaning that he will try to catch you with his bus and drive off towards the blast line, [[OneHitKill instantly KOing]] you if he manages to get past it. While you can get out of his bus by mashing buttons, it becomes more difficult to escape the more damage you have taken. Trying to attack Luigi while avoiding getting caught by Kapp'n isn't as easy as it sounds, especially considering that the stage becomes more and more cramped the longer the battle takes. Kapp'n will always respawn on the stage after driving out of bounds or after you manage to escape from his bus (and he has a rather nasty habit of spawning above you) and you can't KO him either, meaning that you will constantly have to run and jump all over the place unless you want to end up in his bus. The Luigi AI is also smart enough to knock you ''right into'' Kapp'n! [[SarcasmMode You're going to have fun with this one]].
* Not only does '''Deep Breathing''' appear rather early in World of Light, but it is also harder than the conditions make it look like. The fight takes place in VideoGame/WiiFit Studio and pits you against four Wii Fit Trainers with Autoheal each who are all very willing to [[GangUpOnTheHuman gang up on you]]. Given that they are Wii Fit Trainers, their stats are all overall buffed if they use Deep Breathing. Also, did we mention that you only have one minute and a half to defeat the four of them?
* '''Dr. Wily''' is the optional spirit battle of the Base, and boy ''howdy'', is he extremely tough. The fight is a stamina battle on the Omega form of Dr. Wily's Castle against eight Metal Mega Men, who will relentlessly pursue you with deadly ranged attacks, with a combined total of a monstrous 800 HP. Wily himself isn't too tough due to him just being a single Dr. Mario with less HP than any of the Mega Man fighters on their own, but the battle to get to him is extremely difficult. Even with a Franklin Badge, it might not guarantee victory becuase if they get hit with their own Crash Bombs, you won't be able to use close range attacks unless you want it to get stuck on YOU instead. Zoners will have to try to deal with Buster spam, as well as the Metal Blades as well.

* As if one annoying Kapp'n battle wasn't bad enough, let's try the vanilla '''Kapp'n'''. It's you versus Iggy on Wuhu Island locked on the "rocks at sea" section. The rules are "Buoyancy reduced" and "Hazard: heavy wind". This means that you die within seconds of touching the water and (unless you have a Spirit to cancel the effect - which if you've only acquired Spirits from World of Light, you ''don't'' at this point) have to struggle just to move around the stage. Meanwhile, Iggy is completely unaffected by the wind and bounces around the stage, hitting you from every angle and gleefully jumping out of the way of your attacks. The frustration induced by this fight is far beyond what its 9,600 rating would imply - and it's ''required'' that you do this fight, because you need Kapp'n to travel over water and reach the airport island.

* '''Giga Mac'''. He has the tied most power in the entire game, that being 13,900. It puts you into the Boxing Ring with a giant Little Mac to represent Giga Mac himself, and he has Super Armor making him extremely difficult to get flying. His attack speed is also wicked too, draining your HP in a flash. To add insult to injury, his Final Smash gauge charges quickly. The stage's lack of BottomlessPits mitigates Mac's notorious weakness in the air and makes conventional [=KOs=] without wearing down his HP difficult. Autoheal will heal you too slowly to compensate for how fast he's draining your HP too. In addition to this, while he's not immune to projectiles, it won't do you any good becuase he'll close the distance fast and turn you into a crater. And since he's got Super Armor, if you want to attempt PK Fire spam with Ness, the hero of Onett will be Yamcha'd in seconds due to the lack of flinching on Mac's end. Want to try for a close range combatant? Hope you have a counter, becuase if not, Mac will VERY quickly prove [[MemeticMutation he ain't got cheeseburgers in his gloves]]. Even then, if you whiff the counter, the damage will rack up far to rapidly to compensate so then you need to catch up in terms of damage EVEN FASTER. Oh, and even if you have a Critical Healing spirit, you'll both get your Final Smash around the same time, so if he hits you with it you'll pretty much be back to where you were before the heal. K Rool is also a no go since the Belly Armor will be broken in seconds if you were relying on it to tank the damage, and Glass Cannons and Fragile Speedsters won't be able to rack up damage enough to catch up and compensate for how much damage you're going to take in ONE HIT. Good luck trying to beat him because the title screen theme from the Wii ''Punch-Out!!'' game will be stuck in your head for a while. To quote Nathaniel Bandy, [[https://youtube.com/watch?v=EDmGMr00Fs8 "I was purely shocked with his destruction and left with a complete loss of words."]] And if you ever beat this one without any spirits on you, you're either lying or just cheesed him with the stage's set-up.

* '''Ashley''' is a weird case. You have to deal with both a very competent Mii Swordfighter (dressed as Ashley, of course) and a tiny Ridley, on a hazard-filled [=WarioWare=]. It also starts with an Ashley assist trophy, who is already an annoying assist (and you can't even harm her at all). Most importantly, however, is the stage-effect, where every once in a while your controls are flipped. While this can be nullified by a Support Spirit, spirits that provide immunity to this effect are very rare, and in World of Light itself it's almost-guaranteed you won't have it by the time you square off with her. The result is that most players end up trying to brute-force a nearly unbeatable fight instead of hunting for an ability they may not know exists.

* '''Dry Bowser''' can be downright brutal to defeat properly. It isn't bad enough that the Battlefield form of Reset Bomb Forest is completely covered in lava and thus forces you to waste two Support Spirit slots, oh no. This fight also gives (Dry) Bowser the ability to receive curry effects at random points as well as gain a defense boost through the time it's effective, forcing you choose between whether you want lava immunity or a Franklin Badge since you can't have both together, as both abilities require two slots. And worse yet, Bowser is no joke to fight against either, feeling downright merciless to you even before his first curry effect comes into play. All that can be said now is that you'd better have powerful spirits ready by the time you go facing off against him, because defeating him without one of the best is next to impossible. Oh, and did we also mention that '''this''' is the spirit that is [[BeefGate guarding Daisy's fighter battle in World Of Light?]] Yeah, good luck if you want to play as the princess of Sarasaland in that game mode.

* The '''[[VideoGame/DonkeyKongCountry Funky Kong]]''' Master Spirit takes place in Kongo Jungle and puts you against Captain Falcon, Donkey Kong, and Diddy Kong, who will all eagerly pick up the constantly spamming Bullet Bills and fire at you with scarily competent aim. It's not much of a problem if you use a Support spirit that gives you the Franklin Badge, but you better be careful of not having an attack make you drop the Badge and have one of the enemies steal it from you. Also, watch out with where you aim your Bullet Bill if you get one yourself; one false move made can end you just as quickly as any of the CPU's Bullet Bill attacks. This is also one of the Spirit battles that unlocks a store where you can buy certain spirits ''exclusively from Funky Kong's shop'', so you'll have to earn the right to enter Funky's shop in order to complete the spirits list.

* Don't let '''Kapp'n ([[VideoGame/AnimalCrossingWildWorld Wild World]])''' fool you just because he is an Advanced spirit. You face off against Luigi in a stamina battle taking place in New Donk City Hall. The main problem surrounding this fight is that the Kapp'n Assist Trophy appears, meaning that he will try to catch you with his bus and drive off towards the blast line, [[OneHitKill instantly KOing]] you if he manages to get past it. While you can get out of his bus by mashing buttons, it becomes more difficult to escape the more damage you have taken.

The Luigi AI is also smart enough to knock you ''right into'' Kapp'n! [[SarcasmMode You're going to have fun with this one]].

* Concluding the trend of inhumanely difficult Legend-class DLC spirits, we finish things off with Sora's very own Nobody, the Key of Destiny himself, '''Roxas'''. [[ThatOneBoss Are you]] [[VideoGame/KingdomHeartsII scared]] [[VideoGame/KingdomHeartsCoded yet]]? [[OhCrap You should be.]] This stamina battle in the Roxas "Dive to the Heart" form of Hollow Bastion pits you against a Sora with 160 HP to your 150, as well as increased move and attack speed every so often. The trouble is, he also starts equipped with a Killing Edge, and he will heal once you get him down to 80 (all but guaranteeing that he'll be able to build up his Final Smash), [[GuideDangIt neither of which the game tells you about]]. As you'd expect, the AI is hyper aggressive, refusing to give you any breathing room. He'll use Sora's entire bag of tricks against you, flinging magic to cover any distance, charging with his Sonic Blade, and pulling out a counter if you get sloppy. And because the spirit has a whopping 13,800 power and a Neutral affinity (meaning you can't weaken him by selecting a primary of opposing type), you either use a high power spirit of your own, limiting your support options, or weaken yourself in order to get auto healing that you WILL need to compensate.

* '''Black Shadow''' is an exclusive Spirit Board challenge that is a Legend with over 13,000 power. This fight contains both a Captain Falcon and a slightly larger version of Ganondorf in Port Town Aero Drive. These two when together can knock you off the stage very quickly, and proceed to double on you, and Ganondorf hits like a truck with his Smash Attacks and Reverse Warlock Punch. It is very likely for you to get hit by their attacks, smacked off the stage and into a meteor smash from the Captain Falcon or Ganondorf, causing a defeat. Then there's the fact that you take sudden damage constantly, so you could be safe from one attack only to die from that attack in the next second. Even with some of the most powerful Legend spirits in the game, this fight can cause you to lose a lot of rematch items. For F-Zero fans, this reflects on the challenges of trying to beat Black Shadow and Blood Falcon in Chapter 7 of ''F-Zero GX'''s [[GuideDangIt Hard Story Mode]] keenly well.

* '''Articuno, Zapdos, and Moltres''', another Spirit Board exclusive. The legendary birds are represented by three Lucas fighters who each spam PK Freeze, PK Thunder, and PK Fire and the battle itself takes place in the Battlefield Form of Find Mii. They’re also really aggressive, and due to the fact that they all have 60 HP, they’re almost guaranteed to swarm you and ensure you never get a chance to fight back.

* '''Baby Bowser''' is yet another Spirit Board-exclusive that can be a major pain in the butt. It's a stamina match against two Bowsers, one tiny and one giant, on the Omega form of Find Mii entirely covered in lava, meaning a lava immunity Spirit is an absolute must. While the tiny Bowser isn't that overly difficult, the giant Bowser is a major pain to kill, as he has super armor and will spam his most powerful attacks which hit like a truck, and if you're not good at dodging can (and probably will) reduce your stamina from full to zero in literally seconds. You can easily recover all your Stamina if you chose Ness, Lucas or Mii Gunner (If you have Absorbing Vortex) and throw your PK Shield the moment you see Bowser spitting fire (which is scaled up to cover the entire stage), but you'll still need to resist a long fight and don't get overconfident.

* While '''[[VideoGame/JoyMechFight Sukapon]]''''s Spirit Battle isn't in World of Light, it does have a rare chance of appearing on the Spirit Board. This fight is twice as bad as Rayman because Sukapon is a Legend spirit with 13,700 power and puppets a Mii Gunner with 180 HP in a Stamina Battle. This Mii Gunner is extremely aggressive and nimble, preferring to zone you with her multitude of ranged attacks to make avoiding Sukapon almost impossible. Thanks to the enemy's high HP and [=AI=] level, it's more than likely you'll have to [=KO=] Sukapon ''twice'' before the fight is over. And to make matters worse, the Mii Gunner periodically gets a damage buff to keep the pressure on you even if Sukapon is gone. Your best bet with this one might be being cheap and taking it outside of the stage's boundaries quickly, if you can do so.

* ''Dragaux'' pits you in a Stamina Battle against a Giant Incineroar in Omega Find Mii. After losing half his health, he not only gets even bigger, but becomes Metal, making him hit like a train with little space for you to dodge.
