Fanfic / Equestria: Across the Multiverse

Go To

“When considering the history of multiversal exploration in Equestria, one must remember that the groundwork for travelling between universes was already established long before the time of Princess Twilight. While it is true that Princess Twilight had begun the modern age of multiverse exploration, she merely perfected the method of traversing parallel worlds into a practical form, and her endeavors began as a private project exclusive to only her and her companions.
Even so, however, without her insight into the full implications of its potential, modern trans-universal colonization and commerce would never have occurred. And without her support and efforts to gradually expand this endeavor into a national, then international, and eventually cross-universe enterprise, the benefits and impacts of inter-universal travel upon this Equestrian society and many others would never had been fully realized.”

Looking Glass, Earth-Pony Historian, “Crossroads of Infinity: A brief history of inter-universal travel” [Equestria Variant AXC-15274]

Equestria: Across the Multiverse is an ongoing Round Robin My Little Pony: Friendship Is Magic fanfic series by Brutality Inc, Godzillawolf, Alex Warlorn, and many other writers.

Inspired by her previous adventures with Sunset Shimmer's world and wanting to continue in Starswirl's footsteps, Twilight, with help from Sunset Shimmer and company, invents a portable transdimensional portal projector. What follows is an exploration of the multiverse, visiting many strange, wonderful, and terrible worlds across existence.

This series contains examples of:

    open/close all folders 

    A to C 
  • Adaptational Wimp: The Gods War Arc versions of Amicitia and Harmony are both this compared to their original incarnations. In the originals, Amicitia is one of the strongest entities in creation and capable of planet buster level magic, while Harmony is a Top God and evenly matched with the Bridge version of Bagan and would have completely demolished Grand King Ghidorah with less than half her power. Here, they're much weaker than Gojira to the point Bagan (who's stronger than Gojira but nowhere near as powerful as the Bridge Bagan) easily killed Harmony, who while powerful would be considerably weaker than either. Somewhat justified with Amicitia considering the lion's share of the original's power is currently in Halflight Midnight and Amicitia's other spawn, rather than this version recreated from her.
  • Alien Geometries: The Tenth Dimensional Ponies and their realms are this, at least from the perspective of nonascended ponies and in their true forms.
  • Alien Sky: The Twin Worlds Arc sees Daring Do's team arrive on another Equus. While they notice small differences... eventually Soarin' notices that there's another planet in the sky, revealing they're on a double planet system.
  • The Alliance: The aptly-named Multiverse Alliance, a coalition of parallel worlds which had united in friendship for the purposes of trade and mutual aid, with Mainline Equestria as one of its founders and leading members. The Alliance came to the aid of Mainline Equestria against the alternate Flim-Flam Brothers' Invasion and the forces of the Storm King.
  • Alliance of Alternates:
    • The Mane Six often team up with their native selves if needed.
    • During the Flim Flam Brothers' Invasion, Rainbow Dash teams up with Princess Rainbow Dash from Speed World and Shining Armor teams up with Sincere Heart, his alternate self from Ponyland.
    • Several dozen Pinkie Pies come together... to prepare the jaunting base for a Hearth's Warming party.
    • The Alliance in general counts, as Celestia, Luna, Cadence, and Twilight are the leaders in a large number of universes composing it.
    • The Grand Changeling Compact, a subgroup within the Alliance, is composed of many different Changeling monarchs, but obviously a number of Thoraxes and benevolent Queen Chrysalises.
    • The Discord Continuum is a multiversal alliance of Discords, Accords, and other related entities united...to annoy Twilight Sparkles and starship captains on a multiversal scale. An obvious Shout-Out to the Q Continuum.
    • A Villain Team-Up of Accords is mentioned as having fought and been defeated by the Discord Continuum offscreen.
    • The Storm Empire is an alliance of Storm Kings from across the multiverse formed out of strength in numbers. They aren't an enemy of the Alliance because they have no interest in making enemies of other big fish in the multiverse, and simply want to focus on keeping their empire running. In addition, not all of them are evil.
    • The Legion of Santas is a multiversal alliance of Santas united to protect the holiday and spread good cheer on a multiversal scale.
  • Alternate Self:
    • The Mane Six tend to run into these a lot.
    • Some universes have ponies who have different names but are clearly alternate versions of ponies. The Lighting the Darkness Arc has Sunny Day and Moonshine, alternate versions of Celestia and Luna, and the Deep Blue Sea Arc has nearly everyone like this, including the Elements (which have their counterparts, the Elements of Unity, which have different names). The Ponies and Giants Arc has the "Giant Six", who despite not being ponies are heavily implied to be the Mane Six's counterparts in that universe.
  • Alternate Universe: The Mane Six are exploring these.
  • Always a Bigger Fish:
    • In the world visited in the Gods' War Arc, the Princesses were killed by King Ghidorah, who was in turn killed by Gojira, who is in turn overpowered by Bagan who in turn is overpowered and killed by a Harmony powered Super Gojira.
    • The Mane Six are this for Lord Yomi's forces, as they're so used to dealing with people they have an insurmountable advantage over that they have no idea how to handle someone they don't.
    • An Eldritch Abomination tries to eat the G3 universe...only for a Tenth Dimensional version of Rainbow Dash to show up and stop it fairly easily.
    • The Berry Triplets call in Godzilla Junior to help save the version of Ponyville being attacked by the Death Crawlers. The four surviving basic ones find out the hard way why Godzilla is the King of the Monsters, with only the Alpha able to fight Junior one on one.
  • Ancient Order of Protectors: It turns out the Isle of Pony's royal family are this. They're protecting caches of ancient magical creatures, artifacts, and more hidden beneath the Isle that could be used to take over the world if they ever fell into the wrong hands. Tales!Chrysalis was very intent on being those wrong hands, but Starlight, Patch, and Sweetheart manage to awaken three of them and send them against her.
  • Anti-Magic:
    • Ponyland developed the Bleacher Missiles, which uses a warhead made with the same mysterious dark stone that made up Chrysalis' magic-draining throne from the FIM Season 6 finale. They were used successfully during the First Multiversal War against the alternate Flim-Flam Brothers' invading aerial armada, draining magic from its targets after impact (And even before that, going through the magical shields like they weren't there) and shutting down the magitech systems on-board.
    • The Silent Brotherhood from the Hegemony are also called the 'Null-Knights', as their very presence could nullify all magic by virtue of being 'Blanks'. They are based on the Sisters of Silence from the 40K setting. Even the Empress' own power is not immune to their effects, though luckily they serve her and are charged with guarding critical facilities and locations.
  • Arc Villain: Several story arcs have their own Big Bad the mane six have to contend with:
    • The Gods' War Arc has Bagan, who's presently attacking Equestria.
    • The Magenta Diamonds Arc has a resurrected King Lavan.
    • The Lighting The Darkness Arc has Lord Yomi, a demon who took over the alternate world.
    • The Everfrost is this for the Deep Blue Sea Arc, which is trying to plunge the world into eternal winter.
    • The Princess Twilight, Ruler of Equestria Arc has Grogar, the awakened ruler of Tambelon who seeks the power to rebuild his kingdom either on Equestria or in another world.
    • Zetton is this for the Kaiju Ponies Arc, attacking the Mane Six and Junior shortly after arriving due to the Zettonians detecting the energy of the portal caster and seeking it for themselves.
    • An alternate version of the Flim Flam Brothers become the first major threat mainline Equestria faces on a multiversal level, attacking them on their homeworld.
    • The mainline Storm King becomes this for the Eye of the Storm Arc, having upgraded himself using the wreckage of the Flim Flam Brothers' invasion fleet to avert Villain Forgot to Level Grind.
    • Queen Chrysalis and Black Star for the "Bearers of Two Worlds Arc".
    • Tales!Chrysalis for the Winter Wedding Arc.
    • Pony Rangers!Nightmare Moon for the "Pony Rangers: Doomsday!" Arc.
    • Bastemon/Catrinamon for the "Digimon Tales" Arc.
  • Arc Words: A few.
    • "The Die is Cast" - repeated across the narrative by different characters, usually referring to the consequences and fallout of the Jaunts. Usually, it is to signify their understanding that it is simply too late to turn back from the Multiverse the moment Mainline Equestria Jaunted, and the best could be done is to simply move forward and face whatever the Multiverse throws at them, reaping whatever benefits and costs it might bring.
    • "[Noun] never questioned ANY order." - repeated mostly by the Mooks of the villains and antagonists in various arcs, usually when they carry out immoral or questionable orders from their leaders. Serves to highlight the ignorance, cowardice and irresponsibility of the Mooks in question to not think about the consequences of their actions, done in mindless obedience for their masters. A few of those Mooks however has or eventually musters the wits, wills and sense of duty to have a Heel Realization and switch to the good guys' side.
  • Ascend to a Higher Plane of Existence: The 10th Dimensional Ponies all collectively did this, becoming higher dimensional entities and functionally omnipotent.
  • Ass Kicks You:
    • An evil human baron in the Ponies and Giants Arc got crushed under Amelia's rear when she slipped on some ice and fell on him rump-first; hard enough to leave a human-shaped dent in her armor. Despite being a 100-foot Blood Knight, she's incredibly embarrassed about it.
    • In another giant pony universe, the Mane Six—and ponies in general—are giants, and Pinkie does this to the native Chrysalis...while playing with a crowd of baby Changelings.
    • A ponified Rox trips on a boulder and does this to a Ram Necromancer and some Uber Troggles. A vindicated Amelia laughs her flank off.
    • Sunny Days also did this to a captured (and shrunken) Warlock during an interrogation.
    • Applejack (made giant-sized by a reformed Luna) does this to a crowd of monsters in the Pony Rangers: Doomsday! arc. Notable for being the only time a lethal instance of this trope was done on purpose.
  • The Atoner:
    • Old Starlight (the temporal duplicate of prime Starlight who had to make it back to the present of the Crystal War timeline from 20 years prior the long way) has long since realized the Bad Future and everyone who died was all her fault for altering time for selfish revenge. Even after Sombra was defeated, she's still wracked with guilt and refuses Twilight's offer to finally get home to the prime timeline to help rebuild and make up for all the suffering she caused.
    • Another Old Starlight is present in the invading Flim Flam Brothers' timeline, having been created the same way and being another of Starlight's temporal duplicates. Like the above, she's come to feel immense guilt for what she did and risks herself to escape back to the prime timeline and warn them of the incoming invasion as well as help defeat it in atonement for her mistake.
  • Awakening the Sleeping Giant:
    • The Storm Empire is well aware of this trope, and as such refuse to antagonize other worlds outside their control for fear of bringing one down on themselves.
    • Tales!Chrysalis ended up doing this when her assault on the Isle of Pony ends up resulting in the world's native, previously hidden Unicorn, Pegasi, Flutterpony, and Sea Pony kingdoms deciding to intervene and join the fray against the Neo Hooviets.
  • Badass Boast: In the Lighting the Darkness Arc, Applejack gives one to a Lesser Demon.
    Lesser Demon: You dare defy me, mortal?!
    Applejack: Nah, we dare kick yer sorry flank.
  • Badass Teacher: Cheerilee's twin sister Cherry Blossom may be a better fighter, but she did fill in for Cherry as the Mysterious Mare and learn to fight. And has access to a Mass Production Paladin Armor suit (though one meant more for search and rescue work). When she finds out her Cheerilee's Garden counterpart is trying to murder her class, she goes straight up Implacable Man on her. Though ultimately defeats her in a less than violent way when she catches her. She later holds off the Alpha Death Crawler using a Construction Paladin Armor while buying time to summon help.
  • Bait-and-Switch: Cheerilee looks ready to attack an evil alternate version of her upon finally catching up with her. Turns out she was just pinning her down so she could talk her into giving up.
  • Be Careful What You Wish For:
    • In the Magenta Diamond Arc, Discord gives Silver Spoon her request to be a Gem so she can fuse with Diamond (who is a literal Diamond). Not only does the programming cause a lot of problems, Discord finds that he can't reverse it. Notable that Discord himself didn't mean for it to backfire.
    • Tales!Chrysalis wanted to take over the Isle of Pony and form her own kingdom...her final fate is being banished to a habitable, but utterly lifeless, Equus in a dead universe; and she's made partially immortal so she can't simply commit suicide or starve herself. There are also myriad security systems to make sure she can not escape or be rescued, EVER. She'll be alone forever, in a kingdom of one.
  • Becoming the Mask: One timeline the mane six visit sees Thorax and his brother Pharnyx's having experienced a role reversal with Thorax being the tough and aggressive one with his brother as the meek one. General Thorax actually did intend to just use Spike to invade the Crystal Empire...but gradually genuinely became his friend and betrayed Chrysalis to defeat her.
  • Behemoth Battle:
    • God's War and its spin offs feature several, normally pitting heroic kaiju vs King Ghidorah or Bagan. The Mirror Universe version has a good King Ghidorah and Bagan vs a possessed, evil Gojira.
    • The Kaiju Ponies arc naturally has this, with the first one shown being Godzilla Junior and the kaijufied Mane Six vs Zetton.
    • The Final Battle of the Eye of the Storm Arc is Rodan, Ultramare Harmony, and Seiryu vs the Storm King's Humongous Mecha Zeus.
    • A science fair ends in one when Princess Apple Bloom from Bright Future and the Mechanicum tech-priests of the Hegemony get into an escalating competition ending in Apple Bloom's Ultra Battle Bot vs the Mechanicum's Warlord-class Titan. After both mechs wreck each other, they start building bigger ones until their respective Twilights put a stop to it.
  • Beware the Nice Ones: The Mane Six as a whole. They always come in peace and want to make good relations with the natives. If the natives aren't so good, however, they're not afraid to defend themselves or kick flank to help people.
  • Blocking Stops All Damage: One universe involved is Them's Fightin' Herds. The natives of that particular universe can invoke this trope, which confuses people of other universes.
  • Boring, but Practical: Platformer Equestria's unique magical techniques tend to be fairly basic, such as anchoring yourself in place or a Shockwave Stomp, compared to some of the other world's unique ones, but they're also comparably easy to learn and useful in a wider number of situations.
  • Bottomless Magazines: Played with, as it depends on which universe a person is from. Also justified in many cases as Bag of Holding spells exist and thus magazines with a far larger capacity than normal are entirely possible.
  • By the Power of Grayskull!:
    • The Advanced Paladin Armors have "Paladin System Activate! Armor On!", the mass production models omit the first phrase and simply use "Armor On!". It's also a voice recognition security check, which is why the mass production versions (which aren't assigned to any single user) use the shorter phrase. The same is true of the Bard Armor, likely because it's impossible to use by anyone without Innocence Magic to begin with. The Black Ops mode is activated by saying 'Black Ops mode, engage', and can be turned on regardless of whether or not the armor is activated.
    • The RANGER Armor simply uses the phase "Equip!"
    • The Blackguard armor uses "Codeword: Wish in the Dark." In this case, it's a voice recognition and password to activate the armor.
    • Tales!Chrysalis's armor uses "Dark Queen".
    • The Guardians of Innocence, being Magical Girls, have "Time to play!" as theirs.
    • The Kamen Riders naturally use some variation on "Henshin!", though Gilda uses "Amazon!" being an Amazon expy.
    • The Pony Rangers of course have "It's morphing time!" followed by their animal name. The Prism Rangers have the same, but use "(Insert Color Here) Prism Power!" instead.
    • The Beetleborg CMC have "Beetle Bonders! Beetle Blast!" This is also done by Pony Rangers!Babs Seed when she borrows the White Blaster Beetleborg powers.
    • Checker Monarch/Grimlord has "Forces of darkness, empower me! Take me back to my virtual reality!"
  • The Cavalry: Many of the more powerful allies to the Jaunters become this in time, with figures like Seiryu and the Amalgam'verse Kaiju getting called in when the situation needs the big guns.
  • Calling Your Attacks:
    • The Paladin Armor's users yell "Magic Surge" when going for a Finishing Move. Justified as the vocal statement activates the function in the suit.
    • Given their home universes, the Legendary Riders, Beetleborg CMC, and Pony Rangers all do this, though the Beetleborgs do it the least often. Ultramare Harmony also does it with her attacks.
    • Users of Fabulousity (a power that people from a specific Equestria can use powered by how fashionable they are) do this with poses, which become Ki Manipulation in their hands.
    • As in canon, Digimon do this as well.
  • Came Back Strong:
  • Central Theme: A few.
    • No one can achieve anything meaningful on their own, especially in a place as incomprehensibly vast and dangerous as the Multiverse. But when individuals, groups and nations work together for a common cause, no matter how different they are to each other, they can achieve even the most impossible of miracles and change the course of destiny itself. In this regard, friendship is truly magic.
    • All advances and progress that changes worlds for the better will often come with unforeseeable costs or consequences. They could bring great rewards - but could also easily bring great disaster if done recklessly, venturing into the unknown without preparations. What one can achieve or acquire, another person can also do as well - and they would not necessarily use it for the good of all. But even so, the rewards and benefits from it if done right makes progress worthwhile.
    • Just because you have acquire new powers, tools and allies to help you, that doesn't always automatically mean the problem will become easier to solve.
    • Be ready for anything - reality can truly be stranger than anyone can even imagine.
  • Combat Pragmatist: The Sea Ponies don't have a problem with forgoing flashy tactics, and simply lassoing a non-aquatic foe and dragging them under the drink. The Neo-Hooviet Fleet found this out the hard way.
  • Combining Mecha:
    • The Mane Six arrive in a universe were the natives are robots. Turns out that robot ponies can combine if they've got a close enough bond. The robot Mane Six can combine into an Alicorn named 'Harmony.EX' while the Crusaders can form one named 'Crusader.EX'. According to Crusader, the native Silver Spoon and Diamond Tiara can do it too.
    • The above world contributes the 'Combination Matrix' for the Paladin Armor, allowing two suits to combine the same way. The main reason for this is to be used in conjunction with the Fusion Dance ability from fusion world to create a larger, strong suit to go with the fused pony.
    • Traveler, a Brave Series inspired mecha created by the Matrix of Nobility, can combine with two support mecha to form Great Traveler and with the Thunder Child to form Thunder Traveler.
  • Cool Airship: Equestria uses their new Magitek to create mana-engine powered aerial battleships armed with missile launchers and maser cannons for use in combat if the need arises which are first deployed against the Storm King's armada. When he turns out to be a bigger threat than anticipating, they launch their first super aerial battleship: the Great Harmony, a 1000 feet long, 70,000 tons Magitek flagship with the fixed forward-facing Hyper Mana Cannon as its most powerful weapon and could deploy aerial fighters like the Boltwings and surface troops from its hangars.
  • Crazy Cultural Comparison: Naturally happens a few times, as even very similar Equestrias can have big differences due to For Want Of A Nail. At one point 8-Bit and his counterparts do this while trying to localize video games, and find that the Size Symbiotic Equestria has no concept of single player games due to their nature, while co-op games are the norm, and Ocean World has no concept of dry land or walking. Or hind legs for that matter.
  • Crisis Crossover:
    • The 10th Dimensional Ponies summon one of these to deal with 10th Dimensional Tirek.
    • The first of these such events comes when an alternate version of the Flim Flam Brothers invade using a robot army, prompting Equus to assemble an army of their allies to fight them off.
  • Crossover: The Mane Six aren't limited to just pony universes and some of the universes they visit are crossovers:
    • The Gods War and Kaiju Ponies Arcs are Godzilla crossovers. Though the latter is also a crossover with The Bridge. The former is a world already having a crossover while the latter is well before the crossover actually happened.
    • The Magenta Diamonds Arc takes place in a world having one with Steven Universe.
    • The Under The Red Sun Arc is a crossover with Dark Sun.
    • The group finds themselves in Santa Claus Conquers the Martians at one point. The Green Martians from Barsoom, no less.
    • The Ponies and Giants Arc setting is adapted from Ponies and Dragons, where it appeared as a tabletop game.
    • One universe they arrive in is a crossover with the Ultra Series.
    • One they visit after picking up Factory Scootaloo as a Guest-Star Party Member is a universe where the Cutie Mark Crusaders are the Big Bad Beetle Borgs.
    • A brief jaunt has them meet the tank-girls form Panzermadels.
    • The Mane Six run into Octodad at one point.
  • Curbstomp Battle:
    • The Mane Cast dish out a lot of these during the Lighting the Darkness Arc, due to being stronger than Lord Yomi's witches and warlocks, who are so used to being invincible that they had no idea how to fight someone who can actually harm them. One that stands out is Rainbow Dash vs Fubo, as unlike his fellow Kings, he's too Unskilled, but Strong to keep up and gets thoroughly thrashed when faced with someone as strong as himself.
    • Rainbow Dash ends up fighting Factory Rainbow Dash. At first it's an even Mirror Match...and then Rainbow sees the native Scootaloo and realizes why she's there. She instantly goes into her Rainbow Power form and hands Factory Dash her flank.
    • The first half of the Mane Six's fight with the Metal Mane Six doesn't go very well for them with the exception of Metal Twilight and Metal Spike vs Twilight and Spike, until they use their Paladin Armor to even the odds.
    • The Royal Guard and police in Paladin Armor vs the Crimson Dragons, a criminal syndicate. The armor lets them walk through everything the Dragons send their way and quickly dismantle the syndicate.
    • The Space Legionnaires of the Hegemony's against pretty much EVERYONE they came across, due to them being elite and enhanced super-soldiers based on the Astartes from 40K. It took the likes of a giant Mechanical Monster, the Uber Troggles and their Ram Necromancer masters for them to meet their match. Captain Cerberus and her squad's boarding action during the First Multiversal War had been described less as a battle and more as a bloodbath.
    • The Giant Six (with the Mane Cast supporting) clear out Bandit Pass, a very heavily defended brigand camp, within hours, literally crushing almost everything in their way...and that was them holding back. If the Mane Cast hadn't insisted on a mostly non-lethal approach, it would have been a slaughter.
    • Alliance forces vs. a traitor daimyo's army in the Ninja Six's world. With the Riders, Giant Six and others helping out, Gladstone never had a chance.
    • The Berry Triplets call Godzilla Junior in his pony form when the portal can be reopened to help stop the Death Crawlers. Within a few moments of his arrival, the four surviving basic Death Crawlers are dead. Subverted with the Alpha, which proceeds to get in a long drag out fight with Junior.
    • A trio of Normal Fish in a Tiny Pond psychotic bullies who like going on killing sprees in G3 based worlds for sport arrive in the World of Empathy and find themselves facing Kimono. Kimono defeats all three without ever attacking once simply by tanking or dodging everything they have until they collapse from exhaustion and one has a Heel Realization.
    • Catrinamon and Samudramon give one to the heroes following their digivolution to Mega via the Rainbow of Darkness, more or less beating the Digidestined 7 into the ground without even trying after knocking the jaunters away. After Twilight and the Mainline Tales 7 rejoin the fight with the prototype Power Up system for the armor (activated out of desperation), it turns into a Curb-Stomp Cushion while the Twilight and her Patch, Starlight, and Sweetheart along with their counterparts and their partners hold them off so that the rest can defeat Huntermon and CaptainHookmon so all of them can try and beat the two Megas together.
      Digimon!Patch: Well...at least we actually HIT him that time. That's an improvement over getting 'our flanks kicked into the ground.'
      KnightGreymon: Sadly, you have a point, ma'am. 'Getting our butts kicked' is indeed an improvement over 'butts kicked into the ground.'
  • Cuteness Proximity: When visiting a world where ponies are giants compared to Equestria's other races, Pinkie and Rarity take to a crowd of baby Changelings and a Diamond Dog puppy; respectively. Pinkie lets the little 'Lings sleep in her mane, and Rarity gives the pup giant-sized snuggles.

    D to G 
  • David vs. Goliath: During the Gods War Arc, the visiting mane six use their Rainbow Power forms to hold off Bagan while the native Twilight and Amicitia try to patch up Gojira. While they can't hurt him much, they're too small and nimble for him to effectively counter attack in return.
  • Disc-One Nuke: What certain members of the Multiverse Alliance such as the Hegemony of Equuskind and the Kaiju worldlines effectively became for the heroes' side, owing to the amount of power they have at their disposal on an organizational and individual level. Needless to say, things become a lot more interesting when their aid is rendered unavailable for one reason or another.
    • Example 1: the Hegemony of Equuskind is The Heavy of the MA, being a highly-militarized, expansionistic and ruthless galaxy-spanning empire (Read: MILLIONS of worlds) chronologically around 30,000 years in an alternate far future ruled by a God Empress that's a Lighter and Softer (but by no means nice) version of the Imperium of Mankind, and is explicitly based on it by its founder and ruler. This allows the MA to hold a major advantage in many serious military conflicts, as most other world-lines are not that advanced and most threats from across the Multiverse so far are limited to only a dozen worlds at most, while the amount of resources, personnel and firepower available - as well as the Imperials' willingness and experience in using it - is incredibly hard to match.
    • Example 2: The Intergalactic Federation of Friendship, Bright Future Equestria's worldline, is potentially an even greater Disc-One Nuke, being an INTERGALACTIC association of millions of CIVILIZATIONS united in peace and friendship, with a sizeable portion of its population (Most of Equus for Bright Future Equestria) having ascended into gods, with individual members possessing powers and abilities to rival entire fleets, armies and civilizations. However, they subverted this by not deploying their potential at full, out of fear of making other less developed worldlines overly-dependent on them.
  • Dimensional Traveler:
    • The entire point: the mane six explore the multiverses. They also stop at a 'rest stop' between the multiverses specifically for people traveling the multiverse.
    • There's also Lady Babylon, a dimension jumping Jerkass Genie.
  • Eldritch Abomination:
    • The Unknown Powers Arc deals with a world being attacked by entities of this level.
    • In the Bright Futures Arc, the ponies of the future have had to deal with things of this sort. They won.
    • Technically the Tenth Dimensional ponies are this, as their true forms are so incomprehensible a universe-eating Eldritch Abomination can't comprehend them. Unlike most examples, they're benevolent and actively protect other universes.
  • Elite Mooks: The mainline Storm King is aware of the Hegemony would be a problem for him, so he gets some help from Ispita and recruits some Adaptational Badass versions of the G1 Troggles and powers them up further to become equal to Warhammer Orks specifically to counter them.
  • Enemy Summoner:
    • Button Mash and his father 8-Bit in the Bright Future timeline are this, being the Alicorns of Gaming and Roleplaying respectively. Button can summon armies of video game characters while 8-Bit can summon table top RPG characters.
    • The Ram Necromancers commanding the Uber Troggles during the Eye of the Storm Arc can summon shadowy familiars to attack their enemies.
  • Evil Cannot Comprehend Good:
    • Ulna, a slaver the Mane Six capture early on in Under The Red Sun, is pretty much shell-shocked when Pinkie helps her up when she falls after being startled by the latter. Even after Twilight insists she won't be harmed, Ulna still addresses Twilight as her Mistress; likely thinking she will be enslaved.
    • Lightning Chaser, a crew member of the flagship boarded in operation Jolly Roger, can't understand why he and the other prisoners aren't being tortured or enslaved after the battle.
  • Evil Counterpart: Several are met or mentioned.
    • Dastardly Do, an alternate version of Daring Do from Mirror Equestrias. In contrast to selfless, brave and heroic Daring Do, who's dedicated to uncovering and preserving ancient history and artifacts, Dastardly Do is a selfish, cowardly and villainous pony who is more interested in turning a profit from finding/stealing artifacts to sell for the highest bidder, and is mentioned by her heroic archnemesis as a 'psycho'. She is later revealed to be running a major cross-dimensional artifacts trafficking operation, and is seen starting a partnership with Mainline Equestria's Dr Caballeron on that venture
    • Inverted with Mirror Equestria's counterparts of Daring Do's two major enemies: Bravery Blue, who's actually a sane and noble Ahuizotl, and PROFESSOR Caballeron, who is a genuine gentlecolt and heroic archaeologist. Both are mentioned to be in a Friendly Rivalry with each other but shares a common enemy in Dastardly Do.
    • Also inverted for Mirror Equestria's counterparts of Bagan and King Ghidorah in the "Gods' War: Reflected" arc. Whereas both are Kaiju omnicidal maniacs in their respective franchise, here the former is a heroic guardian deity and the latter is a benevolent, life-protecting alien. It is noted that despite looking almost exactly like their evil versions, one could immediately tell they're good simply by their expressions. Played straight with the mutual enemy whom they joined forces to defeat: the 'Tyrant First King' Gojira, who whilst alive was described as a wrathful 'God of Destruction' who destroyed the planet's previous inhabitants, and then became much worse when resurrected ages after his death as a vessel of the hateful, envious spirits of the planet's previous civilization to destroy those who inherited Equus after their Gojira/self-inflicted demise.
  • Evil Knockoff:
    • The Metal Series created by the invading Flim Flam Brothers are mechanical copies of the Mane Six and the Princesses.
    • A mainline Equus gang leader named Shadow Web managed to get a Paladin Badge and reverse engineer it to create the Blackguard Armor.
  • Evil Me Scares Me:
    • The group have apparently run into several evil Twilights. Twilight isn't amused.
    • Rainbow Dash ends up running into Factory Rainbow Dash. She not only royally chews her out and tries to beat her, she outright disowns her as an alternate version of herself when she learns how she treated her Scootaloo.
    • Cheerilee, now jaunting with her sisters, feels this way about her Cheerilee's Garden counterpart when they meet. Thought she's considerably more merciful to her double than Rainbow was to hers.
  • The Empire: The galaxy-spanning Hegemony is a ponified, mostly benevolent expy of the Imperium from WH40K, complete with an Empress. The Empress, an alternate future version of Princess Twilight, outright admits that she based the entire thing on the Imperium, which she visited via interdimensional travel in ages past.
  • Enemy Civil War: Turns out to be the case for the Ram Necromancers and their Troggle troops the Storm King hired. Their worldline's Grogar is long dead, and Tambelon has descended into civil war as factions fought to take his place. They and their Shadow Realm are reduced to such dire straits they had to raid and hire themselves out to other worlds to replenish their resources and acquire weapons and magic needed to continue their war efforts.
  • Escalating War: The Alliance has a science fair, which ends with Princess Apple Bloom and the Mechanicum tying for first in the invention category. The two proceed to have a 'tech off' that gradually escalates over and over until they're having a Humongous Mecha duel and Empress Twilight and Bright Future Amicitia have to come break it up.
  • Fantasy Metals: Adamantium/Adamantine alloys are used in the construction of several of the Alliances main weapons like Seiryu and the Guardian 1 due to being the strongest metal known to Equus.
  • Feed It a Bomb: Spike and Garble end up destroying Metal Spike this way. He and Metal Twilight have a habit of absorbing destroyed robots to grow bigger and stronger, but the last time Metal Spike tries it, Spike manages to set a missile he's absorbing to explode with Garble's help. The end result Metal Spike being destroyed in a Post-Defeat Explosion Chain due to that missile setting off the other weapons he absorbed.
  • First Contact:
    • A large part of the story is this on a multiversal level, with the Mane Six making contact with alternate universes.
    • Eventually the spike in tech level results in the Celestial Ponies, a race of aliens native to Mainline Equus's universe, to make first contact with Equus. While they're the ones who set up first contact, other races native to Stellaria also come with them to Equus.
  • Fix Fic: The Royal Blood storyline is one to My Little Pony: Friendship Is Magic Deviations. By his own admission, Kendell2 wrote it as a Take That! to the source for treating Prince Blueblood as a complete joke, and never bothering to give him proper Character Development despite being touted as a What If? concept. Here, while much of his Jerkass traits were migated thanks to Celestia's guidance, Blueblood was still spoiled and prideful, and harbored resentment towards Cadence for being born an Alicorn and being Celestia's favorite. His drive to surpass Cadence caused him to become vulnerable to Nightmare Moon's dark magic, creating Darkblood. However, he was able to overcome his problems by trusting his Mane Six and acknowledging his own flaws, killing Darkblood for good, and became the Element of Magic to stop Nightmare Moon. He eventually became an Alicorn like he always wanted, and married the girl of his dreams, his world's Rarity.
  • Flat World: One of the Equuses that are visited is this. It's also on top of a planet-sized Alicorn named Mother Equus, who is the native Celestia and Luna's mother.
  • Flawed Prototype:
    • The original attempt to make a Powered Armor to protect Jaunters on missions was very, very flawed to the point it never got to the point of actually being worn by a pony before being scrapped in favor of the Paladin Armor. One of these flaws was snapping the golem wearing it in half.
    • The Power Up Channel System Prototype Model 5, intended as a Super Mode booster for the Paladin System. Twilight outright states it wasn't nearly as effective as intended and a failed prototype for the final model. The main issue is the armor itself is only acting as a channel and minor magnifier for the Platformer World Power Up being used rather than being directly powered up itself, so it's more a Combo Platter Powers than the overall enhancement intended.
  • Foreign Exchange Student: Due to First Contact with Stellaria, the Friendship School gets a number of Stellarian students as these: Dwarf Star the Graviton Pony, Penumbra the Shadow Strider, Electrum the Glowstone Wyvern, and Ragna the Reptilian. Some Equusians were also sent to a similar school on Stellaria as part of the exchange.
  • For Want Of A Nail: Several worlds the Mane Six visit came into being due to differences:
    • Inverted Ages: The nail is older, younger sibling pairs are inverted.
    • In one world visited, it was Rarity who ascended to Alicornhood instead of Twilight.
    • One world is set in a universe where sometime after the Sirens' defeat, they turned Twilight into another Siren to preserve their kind (as they were dying from their broken gems) and she turned the rest of the Mane Six into Sirens as well, though they're not evil.
    • The Deep Blue Sea Arc takes place in a universe where Equus was always covered in an ocean. Other than the obvious, other things are very slightly different such as ponies having different names than their counterparts and Sirens being the native version of Alicorns.
    • The Princess Twilight, Ruler of Equestria Arc takes place in an universe where Tirek had killed the three princesses instead of sending them to Tartarus. Twilight was able to defeat him in their battle and ended up having to rule Equestria herself.
    • The Mane Six's arrival in the Amalgamverse ends up causing the Zettonians to launch an attack upon detecting the portal caster, which wouldn't have happened otherwise.
    • The Gods and Guardians Arc is set in an alternate timeline to the Gods' War Arc. The nail that diverged the timeline was Shining Armor managing to transfer his soul into a Kaiju body to hold off King Ghidorah, saving the Princesses and helping Gojira win.
    • In Mainline Equestria, it soon becomes apparent that the advent of dimensional travel is a big nail. The plot of the movie is completely derailed: Equestria discovers the Storm King's rampage far earlier than in canon due to better communications and prepare to intercept him long before he can reach Equestria...but the Storm King was also busy salvaging and reverse engineering technology from the Flim Flam Brothers' invasion, drastically increasing his army's threat level as well as giving him his namesake power earlier than in canon. The Storm King is now rivaling Tirek when he fought Twilight in terms of sheer power.
    • The first meeting with Tempest gets derailed by Rainbow Dash knowing the Rolling Attack she didn't in canon despite the former's attempt to invoke In Spite of a Nail. When Tempest attempts to petrify the Princesses, Rainbow uses it get the drop on her and cause her to waste the Obsidian Orbs.
  • The Fourth Wall Will Not Protect You:
    • After the Mainline Equestrian Jaunters arrived in an Equestria where the Ponies live with and frequently does 'PS As' with an unseen 'Audience' brought the light the existence of mysterious 'Fourth-Wall Entities' observing and influencing certain world-lines like they are an entertainment show, a report's addendum reveals the Multiverse Alliance has began to consider developing 'Memetic Agents' that could subliminal influence the thoughts and minds of 'Audience', 'Writers' and 'Producers' entities, as defensive measures to prevent them from starting to influence those world-lines in negative ways e.g. making those settings Darker and Edgier, leading to death and misery for those inhabiting them. And if those agents fail, the report recommends with clinical casualness developing stronger, weaponized 'Memetic Kill Agents' that would, ahem, 'permanently sever' their influence from those Equuses. One of these R&D programmes being considered is even named 'Project Basilisk'.
  • Friend to All Children:
    • Pauline of Ponies and Giants. She fondly recounts playing with human children from a village the Giant Six saved from a rock slide early in their quest.
    • Cheerilee is naturally this. As a result, when she starts jaunting with her sisters and meets her Cheerilee's Garden counterpart, she uses her Paladin Armor to put a stop to her child murdering real quick though ultimately just saves Scootaloo and talks her down.
    • At least one visited world had the ponies raising and healing abused human children, brought to Equestria by Discord.
  • Fusion Dance:
    • The girls visit a universe currently in a crossover with Steven Universe, so naturally the Gems are capable of this as in canon.
      • They later visit a world whose natives can perform fusion naturally, and often do so. For example, Rarity and Applejack can fuse into Jeweled Apple.
    • The main universe ponies begin to learn this from the fusion ponies, with Celestia and Luna managing to fuse into Queen Equinox during the Storm King battle and Cheerilee and her sisters manage it to form Triple Berry to fight an alternate Slenderstallion.
  • Future Badass:
    • Everyone in the Bright Future timeline, given they're all experienced deities. Scootaloo and Rainbow Dash are Space Police who regularly fight planet killing Eldritch Abomination tier threats, and Button Mash and his family (including Sweetie Belle by marriage) can defeat an entire planetary invasion fleet by themselves.
    • Technically speaking, the Tenth Dimensional Ponies are technically this, as they exist in the extremely far future. They're also functionally omnipotent high dimensional lifeforms and omniversal guardians.
    • Most Multiverse Tier villains from outside the Alliance are technically this, as they came from universes where won and thus continued to grow in strength instead of losing and being stopped in their tracks.
  • The Future Will Be Better: The key idea of the Bright Future Arc: it's a Utopian future where Equus has No Poverty, ponies ascending to godhood is a streamlined process, technology is hyper advanced, an interstellar civilization has been established, and everything is peaceful and prosperous. There are still evils and villains to fight, but things are bright.
  • God-Emperor: The Empress of the Hegemony from Worldline WHK-400 is practically one, given who she's based on. Also includes Mainline Equestria's Princesses, Alicorn Queen Majesty from a G1 world, the late Queen Equinox in the backstory of the Yomi-ruled Equus, to name a few.
  • Godzilla Threshold:
    • When the Cutie Remark Timeline Flim Flam Brothers invade Prime Equestria, Ponyland and the Hegemony suggest using tactical nukes, Vortex Missiles, and orbital bombardment against them, but ultimately agree that using them should be saved for a last resort.
    • Twilight only activated the Power Up Channel System Prototype Model 5 on herself and the Tales Seven's Paladin Armor, a Flawed Prototype she never had any intent to use, when it becomes clear they can't wait for reinforcements against Catrinamon and Samudramon, and they are clearly completely outmatched against them without it, since a flawed, failed prototype is better than nothing.
  • Greater-Scope Villain:
    • Ispita, the number 2 most dangerous villain in this corner of the multiverse, is largely this, as while she appears directly she has no real investment in the Alliance and doesn't particularly care about them. Most of her antagonism towards them is this via villains she's created or situations she's engineered with no intentional malice towards them.
    • Pony Rangers!Discord serves as this for the Pony Rangers!Doomsday arc, being Nightmare Moon's boss but only giving her one last shot at beating the Rangers and accommodating her plan somewhat.
  • Greater-Scope Paragon: The Pantheon of First Heroes, one of the first beings to ever travel the multiverse and worshiped as paragons of good on many worlds, and striking fear in the hearts of all evil. While their whereabouts are unknown, or even if they're still around, they left artifacts that can only be used by heroic people across many worlds to aid indirectly against the evils of the Multiverse and inspire many to be courageous, valiant, and noble people.
  • Guest-Star Party Member: Factory Scootaloo ends up joining the group on their adventures temporarily, as Rainbow Dash didn't want to just leave her behind when she'd been through the trauma she was in and wants to show her her Rainbow was an exception, not the rule to how things normally are.

    H to J 
  • Happiness in Slavery: As in canon, Pearls are a Slave Race. As such, when the Magenta Diamond-verse Silver Spoon is turned into one by Discord at her own request, a combination of her own submissive personality and the programming Pearls come with as their 'factory settings', she becomes this trope.
  • Harmful to Minors:
    • Factory!Scootaloo was naturally traumatized by the Rainbow Factory, even after Mainline!Rainbow saved her and kicked Factory!Rainbow's flank. Her entire presence in Jaunting is to visit relaxing worlds to help her recover.
    • The Digidestined 7 are still terrified of Huntermon due to being chased for months by him for sport and seeing their friend Unimon permanently murdered by him, even long after defeating him.
  • Heel–Face Turn:
    • Metal Twilight ultimately performs one.
    • As in canon, multiple Tempest Shadows.
    • Cheerilee's Garden Cheerilee makes one thanks to Cheerilee Talking the Monster to Death. Somewhat more justified however, as it happened before she actually killed anyone and thus hadn't gone fully over the edge. She's still in an asylum however.
  • "Hell, Yes!" Moment:
    • The Berry Triplets naturally have this reaction to finally being able to summon Godzilla Jr. against the Death Crawlers.
    • This is everyone on the side of good's reaction to Digidestined Starlight, Patch, and Sweetheart managing to trigger their partners to Warp Digivolve to Ariesmon, VictoryGreymon, and Aniwyemon after largely being on the receiving end of a Curb-Stomp Cushion for the entire fight.
    Captain Crosshairs: (To the villains) Ha! You guys are so screwed now!
  • Hive Mind:
    • The Mane Six arrive in a world were ponies naturally evolved these. They don't have one massive interconnected one, but smaller groups of varying sizes and forming one is equal to earning a Cutie Mark. Unfortunately, a misunderstanding happens and the mane six accidentally get turned into three pairs of hive minds as well. It's later revealed their hive minds became the consciousness of their fusions.
    • The Tenth Dimensional Ponies are also this: they've transcended the concept of singular universes altogether and any pony who ascends to the same level is offered to become part of the cosmic consciousness, though still remain an independent entity. This is shown by there being one multiverse spanning version of them, but multiple normal sized versions, all of which can function independently of each other.
    • Another universe is discovered where everyone is a hive mind entity composed of five tiny identical versions of themselves.
  • "Home Alone" Antics: Invoked in the "Tower Beyond the Sky" Arc, when Teddy, Ace, and Lancer have to fend off a Neo-Hooviet agent chasing them throughout Olympus Station trying to get Tales!Spike (who will grow up into a One-Man Army). Due to not having superpowers or Powered Armor like the girls, they have to run until Teddy notices some maintenance supplies and mentions the Trope Namer, at which point the boys begin fighting back using this trope.
  • Hope Bringer: The Mane Six are this in the Lighting the Darkness Arc, and actively invoke this. They're capable of actually fighting Lord Yomi's forces and overwhelm them, something the natives couldn't. As a result, they actively invoke their Power Pony personas to be more of this trope as superheroes.
  • How Is That Even Possible?:
    • Rainbow Dash questions this when they arrive in a world where everyone is cats. Not anthropomorphic cats, just normal but sapient cats.
    • Twilight asks the same thing when the group arrives in Space Equestria, a version of Equestria where everything is exactly the same except in space.
    • Twilight again asks this when they arrive in a Equestria where the Mane Six, the Princesses, and their Rogues Gallery are all babies living together.
  • Humongous Mecha:
    • In response to the possibility of King Ghidorah existing in the prime universe, Equestria builds a Magitek one based off Gojira, named Mechagojira, or Seiryu.
    • The Guardian 1, a huge search and rescue mecha, is built using the same tech to respond to disasters, though can fight in a pinch if absolutely necessary.
    • It turns out the Storm King's Project Zeus is a 100 meter tall one modeled after himself.
    • Tales!Chrysalis built an Evil Knockoff of Mechagojira inspired by the Showa Mechagodzilla for her invasion of the Isle of Pony.
    • The Pony Rangers naturally have their Zords and Megaponies.
    • The Sentinels, a joint project between the Alliance and Multiverse Police Department, are also this, and intended for fighting monsters, mecha, or villains too large for the operatives to fight otherwise. The smallest one is only 15 meters tall, while the largest is 30 meters. Chief Shining Armor has an Ace Custom version that can combine with a support mecha to form the 50 meter tall Grand Sentinel.
  • I Am Not Left-Handed: Rainbow Dash and Factory!Rainbow Dash's fight starts as a Mirror Match, due to them being the same person from different universes. Then Rainbow Dash sees that her evil alternate self had included Scootaloo in the group of foals lined up to be turned into spectra. She proceeds to activate her Rainbow Power form and completely demolish Factory Rainbow easily.
  • An Ice Person:
    • The Everfrost from the Deep Blue Sea Arc is freezing the world, and has a Frost Talon who can breathe ice.
    • Rowena from the Ponies and Giants Arc is a Frost Giantess with an arsenal of snow- and ice-based magic. She's also Rarity's counterpart in that universe.
    • The ponies from Ice Equestria live in super low temperatures, and are freezing cold to touch. Their Cryomancer armor exploits this by using the low temperatures they need to survive for offensive means.
    • The 'Hidden' Pegasi from Ponyland's universe never greatly explored weather manipulation as their prime selves did, instead focusing on manipulating water vapor in the air. Among the things this let's them do is create various kinds of ice, including blue ice (the hardest known form of ice).
  • I Come in Peace:
    • The Mane Six do this on occasion if they get the chance to, though normally they've got to explain it a little more frantically due to random circumstances, and Twilight gets very frustrated she never gets to properly perform her First Contact protocol.
    • The Celestial Ponies say this when they make First Contact.
  • In Medias Res: Due to the nature of the multiverse, it's very rare the Jaunters arrive at the beginning of the plot of the world they arrive in, and normally arrive in the middle of an already in progress adventure if they haven't missed it entirely. Some exceptions are the Tales Arc and Lighting the Darkness Arc, both of which are caused by the Mane Six's arrival.
  • Implacable Man: Cheerilee uses her Paladin Armor to go this chasing down her Cheerilee's Garden counterpart. Though she doesn't get violent when she does catch her, instead talking her down.
  • Improbably Large Snakes: One world is populated by these, complete with a "Snakequestria" and a Snake!Mane Six.
  • Inn Between the Worlds: The mane six arrive at one run by a tenth dimensional version of Pinkie Pie.
  • In Spite of a Nail: Despite being very different than his prime self, General Thorax from the timeline where he and Pharynx have reversed roles still ends up becoming Spike's friend and overthrowing Chrysalis to redeem the Changelings.

    K to N 
  • Karmic Death: The Jerkass baron in Ponies and Giants. (See Ass Kicks You).
  • Kaiju:
    • The Gods' War Arc has Gojira and Bagan, with King Ghidorah being mentioned.
    • The Gods and Guardians Arc is set in an alternate timeline version of the Gods War world. The nail is Shining Armor transferred his soul a kaiju body to hold off King Ghidorah.
    • The Kaiju Ponies Arc is a crossover with The Bridge, so naturally there's plenty of these, but the twist is that the Mane Six turn into Kaiju when they arrive, with Twilight becoming a Godzilla, Rainbow Dash a Rodan, Applejack an Anguirus, Pinkie Pie a pink slime monster...thing, Rarity a crystal monster similar to Krystallak, and Fluttershy is a Mothra.
    • The prime verse produces a Magitek version of Mechagodzilla to counter the possibility King Ghidorah exists in their universe.
  • Kicking Ass in All Her Finery:
    • Invoked in Fabulosity Equestria, where the better dressed you are the more powerful you are to the point it can make you a Person of Mass Destruction. Though it's not limited to just dresses, as each chic has its own rules of what works.
    • Rowena of the Giant Six. She doesn't let her homeland being a frozen winter-land and having to wear combat armor stop her from looking her best.
    Rarity: [Seeing Rowena for the first time] "She's...so...STYLISH!"
  • Killed Mid-Sentence: A traitorous daimyo in the Ninja Six's world, courtesy of Amelia. He was trying to sneak away, but one of his captured minions recognizes him and blurts that out...
    Daimyo: "I. Hate. Y—" (Amelia steps on him)
  • La Résistance:
    • In one universe, the mane six are rescued by a group against an Equality crazy Apple Bloom.
    • The Lighting the Darkness Arc sees the mane six team up with one operating against Lord Yomi. Their leaders are Celestia and Luna's alternate universe counterparts.
  • Lethal Lava Land: The 'Fire World' Equus is this, being so volcanically active it's pretty much constantly on fire. The ponies that live there evolved to survive in the hot temperatures, but the jaunters need to wear the Fire Rescue Paladin Armor due to the heat. Ironically, because the fire ponies are adapted to the heat, they likewise need to wear special suits to survive on mainline Equus because otherwise the temperatures would be freezing cold to them.
  • Literally Shattered Lives:
    • Super Gojira's Navel Beam does this to Bagan, with the power of Harmony infused into him slowly turning Bagan into stone that is then blown away by the force of the attack.
    • The Baron of Battle is petrified with the Rainbow Powers and shatters on impact with the ground.
    • The Storm King meets his end this way, as in canon.
  • Logic Bomb: Pinkie Pie and Fluttershy manage to do this to Metal Pinkie Pie and Metal Fluttershy by showcasing their rock farmer and assertive sides respectively. This is so outside their programming that it causes them to glitch up to the point of being near helpless. Metal Pinkie Pie was actually programmed to be insane to avoid this trope from Pinkie Pie, but couldn't handle Pinkie being sane.
  • Machine Worship: The Mechanicum of the Hegemony-verse, complete with hatred of AI and a concept of "tech-heresy". Justified in that, like their counterparts from WH40k, their galaxy had gone through an AI revolt from the 'Mare of Iron' which nearly destroyed Ponykind, making them hostile and wary of any artificial intelligence and those who use them, which had strained their relationship with robots and robo-world members of the Multiverse Alliance.
  • Made a Slave:
    • A group of slavers tries to do this to the Mane Six in the Under the Red Sun arc. It doesn't end well for them.
      • The last slaver the Mane Six keep around as a (semi-forced) guide calls Twilight "Mistress", implying she thinks this will be her fate.
    • For his many war crimes under the invading Flim-Flam Brothers, Commander Wind Rider is handed over to the Hegemony for forced labor, loading starship munitions by hoof. And he deserves every bit of misery he gets.
  • The Magic Comes Back:
    • Due to the nature of their mission, the Mane Six naturally cause some of these by sharing Equestria's magical advances as their part of interdimensional trade.
    • Tales!Starlight realizes that if the Super-Empowering the Tales Seven got includes their Earth Pony magic fully awakening, the rest of their Equus can learn to use Earth Pony Magic. The Stinger shows this event caused a new Tree of Harmony to sprout in the Lost Woods in the Tales Verse. It eventually turns out the other tribes are also present in this world, but hidden and separated. The Jaunting combined with Pony!Chrysalis's assault on the Isle of Pony prompts them to reveal themselves and join the fight against her.
  • Magitek:
    • The portal devices use a combination of magic and technology to create portals.
    • Creating this is one of the big draws for trade between the Equestria and Ponyland, as the former has advanced magic and the latter has much more advanced technology, so combining them is a major boon.
    • In response to learning of King Ghidorah's existence in three alternate universes, two of which were Equestrias, Celestia decides to devise countermeasures in case one exists in her universe. Namely, a magitek Mechagodzilla (or Mechagojira as the case may be), also known as Seiryu.
  • Mama Bear:
    • Rainbow Dash was already trying to beat Factory Rainbow to a pulp for obvious reasons. Then she realized Factory Dash was trying to murder her version of Scootaloo in the Pegasus device. Rainbow promptly goes into her Rainbow Power Super Mode and completely demolishes Factory Dash.
    Rainbow Dash: RAINBOW DASH CAN BE A LOT OF THINGS! BUT SHE SHOULD NEVER BETRAY HER LITTLE SISTER! SO STAY AWAY FROM SCOOTALOO!
    • Maternity, Button Mash's mother, is literally the embodiment of this in the Bright Future timeline, having become the Alicorn of Motherhood. She even gets a big power boost if she's protecting Button.
  • Massive Multiplayer Crossover: The Crisis Crossover events can be this, due to the visited universes not being limited to My Little Pony universes and even some that were were having a crossover or ponifications of other series. The first one involves multiple versions of Equestria, many of which are in Metal Heroes inspired Powered Armor, a benevolent ponification of Warhammer 40K's Imperium, Gamera, a Magitek Mechagodzilla, the Crystal Gems, giants both original and inspired by various fictions, a Tomica Hero Rescue Force inspired mecha, and the Big Bad Beetleborgs vs the Flim Flam Brothers' Sonic the Hedgehog inspired robots and Expy of the Bishop of Battle who's also the hybrid son of a Lovecraftian Eldritch Abomination (specifically one heavily based on the Persona 2 version of Nyarlathotep) and a Spirit of Temptation based off of Belladonna who at one point throws a Samurai Jack inspired monster into the mix. And that's just the Starter Villain battle.
  • Mass "Oh, Crap!":
    • The Flim Flam Brothers' forces naturally have this at various points during the invasion when they realize they've attacked a world far stronger than expected.
    • Everyone has this when Bastemon and DinoHyumon digivolve into Catrinamon and Samudramon using the Rainbow of Darkness, especially when Digimon!Bright Eyes' scan reveals they're now both Mega level, a stage the Digidestined's partners have yet to reach.
  • Mini-Mecha:
    • The Storm King has one called Poseidon he built using salvaged tech from the Flim Flam Brothers invasion and stolen magical artifacts. It's powerful enough to fight all four Princesses at once. His Speed World self builds it too using the tech brought to the world by the Jauntings, but it's not nearly as strong.
    • While most of the Paladin Armors are Powered Armor, the Construction model is this, being about 10 feet tall and far more heavily armored for work in construction. The trade-off is it's a Mighty Glacier and not very agile at all. It also requires a heavy equipment licence to use, though Cheerilee is permitted to use one during the Night Without Stars Arc due to the life and death situation she's in.
    • The MAAF Main Battle Mech Mk I ‘TRAJAN’ is another one, being a mass-production battle mecha for the Alliance, which stands at 4 meters, or about 13 feet tall. While much smaller than the Sentinels, it's still very maneuverable, much more so than slightly smaller Construction armor and well armed.
  • Mirror Match:
    • Rainbow Dash versus Rainbow Factory Rainbow Dash. The two are pretty much an even match...until Rainbow Dash sees Scootaloo in danger and activates her Rainbow Power form, which Factory Dash is too far behind to have and gets demolished.
    • Celestia and Luna vs two invading Evil Knockoff mechanical doubles. At least until they get outside the atmosphere and the Princesses can stop holding back.
  • Monster Progenitor: The Werebeast Six were converted into werebeasts by an evil wizard, but their Elements allowed them to retain their minds and morality. Twilight is a Wereowl, Applejack is a Weredog, Rarity is a Werefox, Rainbow Dash is a Werecheetah, Pinkie Pie is a Weremonkey, and Fluttershy is a Wereskunk. This effectively makes them each into the progenitors of their on unique strain of Werebeast, though they also don't take infecting others easily, and normally only do so as a punishment to genuinely evil people, those who genuinely want to with full knowledge of what it means, or as an Emergency Transformation to the mortally wounded who agree to do so.
  • Mook Horror Show: Captain Cerberus and the Space Legionaries boarding one of the Flim-Flam Brothers' invading spaceships is portrayed as an out-and-out slaughter. The helpless crew (who unlike the invading armies are NOT all robots) are gunned down, burned, mind-controlled, and more. The Legionnaires aren't called "Angels of Death" for nothing.
    • When they reach the bridge, all the remaining crew are dead or subdued in seconds. There's even a (heroic) reenactment of Darth Vader's "effortlessly slaughtering soldiers" scene in Rogue One. Downplayed at least for the Space Legionnaires in this case as they had support from other Hegemony's boarding troops who linked up with them.
    • This happened again when the Space Legionnaires face off the Yeti troops of the Storm King during the Storm King Crisis. Some Yetis became so terrified of the Space Legionnaires as they relentlessly slaughtered through their ranks, many killed themselves or jumped overboard rather than try and fight them.
  • More than Three Dimensions: The Mane Six meet a tenth dimensional version of Pinkie Pie who's the owner of the Inn Between the Worlds.
  • Multiversal Conqueror: As the Alliance learns to their horror, the multiverse has no shortage of these. The first one they encounter, the Flim Flam Brothers' corporate empire, is the biggest threat the Alliance had ever faced up until that point...and they didn't even make the list of the top 1000 most dangerous in existence.
  • Mundane Utility:
    • A large point of the exploration is to find useful things to bring back to Equus for use, so naturally there's quite a bit of this.
    • The Paladin System gets special note as invoking this trope is a large part of the trade between the Paladins of Harmony world and Equus Prime: due to their situation of combating Hydia, their research and development is devoted to combat applications. Since Equus Prime doesn't have that issue, they can produce noncombat variants for more mundane use on both worlds, such as fire fighting, exploration, and construction. This is actually Truth in Television, as one of the primary reasons people want to develop Powered Armor in real life is for those exact reasons, especially construction.
    • The technology used to create Seiryu is also used to create the Guardian-1, another giant mecha for use in search and rescue work. While it has combat capabilities, they're more for self defense if needed than it's primary purpose.
  • My God, What Have I Done?:
    • Old Starlight (the one who'd altered the past and took The Slow Path back to the present in "The Cutie Remark" and a splinter version of Prime Starlight) has long since realized she created the Crystal War timeline with her selfishness and had this reaction. The same is true of the version of her from the invading Flim Flam Brothers timeline, as well as the original Starlight after realizing the invasion was all her own fault.
    • Sunny Days briefly has this during the fight with Viper. She uses a Witch as a shield against the demon's spell....which turns her foe into a pile of snakes as she screams in agony. Needless to say, Sunny is horrified.
  • Nice Job Breaking It, Hero: In the Magenta Diamond verse, Discord makes Silver Spoon a Pearl of her own request so she could fuse with Diamond. Not only does this cause Silver to have to deal with the 'factory settings' for a Pearl, Discord finds out he can't reverse it. This sends Diamond into such an Unstoppable Rage that she assumes her true Diamond form and nearly goes through Steven to get at Discord until Silver stops her.
  • Next Tier Power-Up: Technology, magic, and such gathered by Jaunting is this, as different universes excel in different ways with different abilities and thus mixing them can result in rapid growth and progress. The unfortunate thing is, this works as well for villains as it does for the heroes. Also Downplayed, as some worlds' default level is on par with a jaunt boosted world.
  • No Antagonist:
    • Many one shot worlds have no actual villains.
    • The My Little Pony Tales Arc has no antagonist, fitting with the show itself lacking any.
  • No-Holds-Barred Beatdown: Rainbow Dash takes the Rainbow Factory's roof off by literally beating Factory Dash through it with her Rainbow Power form. Factory Dash is left unconscious with more broken bones than intact ones. Factory Dash shouldn't have messed with kill her Scootaloo.
  • No Poverty: The Bright Future timeline has this. According to Princess Starlight Glimmer, it was the result of Filthy Rich ascending into the Alicorn of Economics.
  • Normal Fish in a Tiny Pond:
    • For all their advancements, Mainline Equestria soon find out that they're this in terms of the larger multiverse, as the Flim Flam Brothers corporate empire shows: to the Alliance, it's the biggest threat they'd faced to date and a fair challenge. To the rest of the multiverse? They didn't even make the Multiverse Villain Leaderboard and are considered the equal of a street gang. Needless to say, the Discord Continuum warns the Alliance they need to get strong fast if they want to survive.
    • Riot and his cronies are a trio of average teenagers with modern weapons. Up until now, their targets have been defenseless worlds incapable of fighting back and allowing them to go on killing sprees unopposed. When they run into Kimono, they don't stand a chance.
  • No-Sell:
    • Garden!Cheerilee tries to kill Cheerilee with acid which she'd planned to use on Diamond Tiara and Silver Spoon as she did in the original story. Since Cheerilee's Paladin Armor is designed to survive molten lava, she just waltzes right through it.
    • Kimono does this to everything Riot and his gang throw at her, as her Bard Armor is designed to be a Stone Wall and meant to withstand a lot of punishment unharmed despite having no offensive capabilities. At the end of the fight she simply lets Riot pound on her armor ineffectively until his sword snaps and he collapses from exhaustion.

    O to R 
  • Offhand Backhand: During a fight with some Warlocks, Rainbow Dash manages this.
  • One-Steve Limit: Subverted big time, given due to how many of the same person exist in the multiverse and thus are part of the Alliance. Some do have different names, but most share the same name, and normally look completely identical. This being extremely confusing is pointed out in universe, with nicknames being a necessity.
  • Only the Pure of Heart: Innocence Magic can only be used by a pure hearted person who lacks the desire to knowingly do wrong. It isn't exceptionally powerful on its own, but significantly buffs light magic and weakens dark magic, as well as being a Kryptonite Factor towards corruptive forms of magic.
  • Opposites Attract: Burning Heart and Frost Veil are the first interuniversal couple. They're also from Fire World and Ice World respectively, so their universes are basically polar opposite extremes.
  • Our Giants Are Bigger:
    • The aptly titled Ponies and Giants Arc features these. The ones the Mane Six meet are friendly, and have formed an adventuring party on a quest in the lands of "tinies".
    • They later find themselves in a world with giant ponies who are partnered with tiny ponies (even by the Mane Six's size) in a symbiotic relationship.
    • The Mane Six themselves are the giants in another world; big enough for Rainbow to flatten an acre of forest just by sitting down. Twilight muses that all native ponies are as huge as they are.
  • Our Mermaids Are Different: The native ponies of the Deep Blue Sea Arc are all merponies of different sorts. Sprites have wing-like fins allowing them to fly, Nymphs have magical jewels in their foreheads to allow them to use magic like unicorns, and Merponies have whale qualities and great strength (being the Earth Pony analog). Vuurvis is a merzebra, half zebra half Lionfish (aka, Zebra Fish). According to Word of God, Sea Ponies also exist in this universe. Ironically, Water Guitar (Lyra's counterpart) is obsessed with mermaids like her prime self is with humans, sparking Twilight to wonder if the Equestria Girls verse connected to this universe is inhabited by them.
  • Our Werebeasts Are Different: One world visited has the Mane Six having been turned into Werebeasts by a warlock...but the Elements cause it to backfire and let them keep themselves, turning the tables on him. Not only did they get Werebeast forms out of it, anyone they change will be infected with their morality in their beast form (which resulted in the warlock's defeat when Applejack infected him). Twilight is a Wereowl, Applejack is a Weredog, Rarity is a Werefox, Rainbow Dash is a Werecheetah, Pinkie Pie is a Weremonkey, and Fluttershy is a Wereskunk. They can change whenever they feel like, but have to change at night.
  • Outside-Context Problem: The Mane Six have been this to a few worlds they've visited:
    • In the Lighting the Darkness Arc, they arrive in a world of Earth Ponies without any magic ruled over by an evil demon named Lord Yomi and his minions. The Mane Six's own magic not only allows them to fight Yomi's forces, but is far beyond many of them, meaning they're virtual superheroes there. They're even able to purify 'Forgotten Ones', ponies who have been warped into mindless beasts by Yomi who the natives could only Mercy Kill, something that shocks all present.
    • In the Under the Red Sun Arc, the Mane Six are magic users who operate on a completely different system than anyone present and are capable of spells they don't know. This isn't nearly the advantage it is in the Lighting the Darkness Arc.
    • Garden!Cheerilee is a dangerous, aspiring Serial Killer (having just started her attempted murder of Scootaloo) but she's just a normal pony. Cheerilee prime is already a physical equal to her, so when she activates her Paladin Armor, Garden!Cheerilee is left completely outclassed. Especially considering she only has traps intended to murder foals, not an adult wearing a suit of Powered Armor.
    • The 'Hidden Ones' (the Unicorns, Pegasi, Flutterponies, and Sea Ponies) are this, as while in general they're comparable to the pre-jaunting Ponyland in terms of power, though using magic instead of technology. However, their magic is very different than the Mainline Equestrians, making up for their comparably lower capabilities with being unpredictable.
    • One worldline visited is War of the Worlds alternate Ponylands. It turns out that one of the Pantheon of First Heroes, the Noble Prime, left an artifact called the Matrix of Nobility there, the Tales Seven managed to uncover it and got Brave Series styled Super Robot which was this to the Martians. While not a complete game breaker, it still evened the odds majorly.
  • Person of Mass Destruction: The mainline Storm King, upgraded using pilfered tech from the Flim Flam Brothers' invasion, and the Princesses both qualify: their battle is in the same tier as Tirek and Twilight's and among other things sees a mountain turned into a lake.
  • Powered Armor: The multiverse jumping program starts trying to create Magitek powered armor to protect their other jaunters who lack the Mane Six sheer magical muscle on jaunts. They were having some trouble at first, but then they found a Metal Heroes inspired world that had already produced mass production armor and shared it, allowing them to modify it for various other uses. It soon becomes standard issue jaunting gear and equipment for the guard, rescue work, and police. Ponyland develops their own version called the RANGER Armor, which while still Magitek, focuses on a more technological side of side and uses normal weaponry. The World of Empathy develops another version called Bard focused on being a Support Party Member to the other universes due to their Actual Pacifist nature, so it trades any and all offensive ability for the highest defense of the models and sheer versatility in supportive options for backing up their allies. The Fire World Ponies also make a variant of the Paladin Armor to augment their natural affinity for fire.
    • The Space Legionnaires of the Hegemony wears Powered Armour as part of their equipment, like the Legiones Astartes they are based on.
  • POW Camp: A point of contention among the Alliance once the Flim Flam Brothers and Storm King have been defeated. The varying moral standards and laws among members lead to a rather heated argument about what to do with the prisoners, and it takes Queen Sunsparkle bringing in an adult Megan Williams (of G1 MLP fame) to work out a compromise.
  • Pragmatic Villainy: The Mane Six run into at least one world where the Storm King took over but became a far less harsh despot than in the movie.
  • Privateer: During the battle with the invading Flim Flam Brothers, Luna hires some of these. One of which is Captain Trixie's crew, who promptly start wrecking one of their fleets in another conquered world.
  • Protagonist Title: The Magenta Diamond Arc is named after that universe's version of Diamond Tiara's true name, Magenta Diamond.
  • Psycho Rangers: The invading Flim Flam Brothers built mechanical copies of the Mane Six for use in conquering other universes. They also created versions of the Princesses, but those were destroyed early on. The Metal Mane Six fair far better, and if the Mane Six didn't have their Paladin Armor, they'd have lost. The Metal Mane Six even quote the Trope Namer during their fight.
  • The Purge:
    • A rare heroic version occurs after the events of the "Bearers of Two Worlds" Arc. Fearing future situations where villains local to their world-lines acquire weapons and allies from other worlds to magnify their threat like the Storm King and Chrysalis did, the Multiverse Alliance enacted on an initiative to subdue or eliminate as many known local villains and threats as possible to secure their home-fronts, especially in preparation of facing future threats from across the multiverse, in what history later remembers as 'Operation: Pest Control'. While only a few such operations are depicted, like in Ninja Equestria and in the "Shadow Ops" arc, it is mentioned that the operation is enormous in scale, occurring simultaneously on hundreds of worlds and involves the combined military, agents, champions and heroes both local and drawn from across the Alliance.
    • The potential threat of a purge of changeling commanders that an alternate Chrysalis considered too popular and powerful is partly what drove General Thorax of that world-line to defect fully and plot with the Equestrians to usurp her (besides her questionable leadership of the Swarm and his newly-discovered friendship with the Equestrians).
  • Reasonable Authority Figure:
    • Lord Eranbald in Ponies and Giants. He agrees to negotiate with the Mane Six on the Giants' behalf, and despite his reservations agrees to cut a deal to help them out.
    • All the leaders met in the Tales world are this, being respectful to the Tales crew for past exploits and willing to hear the mane six out. After that, they just want to make sure First Contact goes off well.
  • Rebel Leader: Sunny Days and Moonlight, the leaders of La Résistance against Lord Yomi and Celestia and Luna's alternate selves in the Lighting the Darkness world.
  • Recycled IN SPACE!: Parodied with Space Equestria, with everything nearly identical to the main universe, except everything is in space.
  • Retro Rocket: Space Equestria's spacecraft are this.
  • Rising Empire: The Multiverse Alliance, formed by Mainline Equestria and other major worldlines they had come across such as Ponyland Equus, the Hegemony, Bright Future Equestria and the like, is classified as a 'Nascent Great Power' in the indexes, and is noted for its exceedingly rapid expansion in influence and capabilities across the worldlines.
  • Roswell That Ends Well: One world the mane six arrive in features this. They're the aliens.

    S to V 
  • Sealed Army in a Can: It turns out one of the secrets being protected by the Isle of Pony's royal family is a pack of Shisa, bound in stone and set to awaken to protect the Isle when a prophecy is fulfilled. Tales!Starlight turns out to be The Chosen One and accidentally breaks their primary seal, starting a race to open the vault and unleash them before Chrysalis's forces can locate them and potentially use them for their own ends. It turns out they're not the only army sealed down there, as the chamber is called the 'Chamber of Seven Sleeping Armies' for this reason, just the Shisa were the first to awaken, with Patch managing to awaken the Armor of Valiant Warriors as well. One of them, a dragon egg, is part of it because a full grown dragon might as well be an army, but while Sweetheart wakes him up, the newborn Spike isn't yet old enough to fight.
  • Sealed Evil in a Can:
    • The Everfrost from the Deep Blue Sea Arc was imprisoned in the polar ice caps until escaping.
    • Twilight and her friends make a habit of shrinking wizards and trapping them in bottles during the Lighting the Darkness Arc. Twilight also knows a spell for sealing evil spirits inside weapons that also allows the weapon to use their power. According to her, it was a spell created by Mage Meadowbrook (though it's later revealed to be a joint invention of her and Mistmane).
  • Serious Business:
    • One universe sees reading and book reports as this, to the point every major conflict is resolved by it and you get taught about them in boot camp; complete with a Drill Sergeant Nasty griffon.
    • Another universe has fashion as this, because in that universe being fashionable enough can make you a Person of Mass Destruction and poses are equal to Ki Manipulation.
  • Settling the Frontier: As their population has become immortal, the Bright Future timeline had to take overpopulation into account. When it first came up, Luna terraformed the moon and then made a second moon after that. By that point, they'd advanced sufficiently to explore space and terraform other worlds to inhabit so it was no longer an issue.
  • Shapeshifter Default Form: In the Magenta Diamond Arc, Diamond Tiara is revealed to be a Gem, namely a Diamond, who Rose found and sent to Equus so the Homeworld couldn't find her. She turned into an Earth Pony foal after emerging and thus her recognizable form is actually this.
  • Shout-Out:
  • Silver Has Mystic Powers: During the Lighting the Darkness Arc, Twilight has the resistance gather up all the silver they can get, as silver has innate magical properties that, when combined with runes, could give them a fighting chance against Yomi's minions. This includes upgrading Sunny Days and Moonlight's armor with silver plating and runes.
  • Single-Biome Planet:
    • The Deep Blue Sea Arc takes place on an alternate version of Equus that's completely covered in water, and apparently always been that way.
    • A later world has been extremely volcanically active for eons. As a result, everything is constantly on fire. The natives have adapted to it and are all immune to fire and heat. Ironically, from their point of view, Equus Prime is the opposite trope as it's hypothermia temperatures to their kind.
    • Another world is the exact opposite of Fire World: a world in a perpetual ice age. The natives have likewise adapted to the cold, but have the same problem as the Fire Ponies of Equus Prime being a temperature extreme to them.
  • Slippy-Slidey Ice World: Ice Equestria is this, being in a constant ice age due to being further away from the sun. The native ponies have adapted to the cold, but the jaunters need to wear Paladin Armor to survive there. Ironically, much like the Fire Ponies, the temperature of mainline Equus is inhospitable to life for Ice World inhabitants and they need to wear life support suits there.
  • The Slow Path: After arriving in the Crystal War timeline, Twilight discovers that because Starlight stayed in the past every time, a temporal duplicate of her existed in the alternate timeline and had to take this back to the present. 20 years of dwelling on her sins and seeing the true cost of her revenge has left her with quite a different worldview than she started with. The invading Flim Flam Brothers timeline is home to another duplicate who has likewise come to the same conclusion and decided to help fix the mistake she made.
  • Smelly Skunk:
    • The Mane Six arrive in an Equestria were an encounter with an evil warlock turned their native selves into Werebeasts, but the Elements let them retain their mind and morality. Fluttershy is a Wereskunk, with all that implies, as is anyone she were to infect. Notably, her Wereskunk form is portrayed realistically with spraying a horrid smelling liquid from the base of her tail that temporarily blinds the victim if it gets in their eyes. Because she's gigantic compared to a normal skunk (especially given her Wereskunk form is much larger than a pony), she also has far longer range and sprays a lot more at once. It's surprisingly effective, and she manages to effectively neutralize attack helicopters by spraying the gunner, as it's rather hard to fire accurately when you're temporarily blind and coughing your head off.
    • Were!Fluttershy bit and infected Tales!Kabuto, turning him into one as well. His guard finds out the hard way every night when he transforms and rescues his own captives under the curse's influence, normally spraying the grunts in the process.
    • Another universe has skunks having evolved as the primary sapient species rather than ponies. They're also realistic depictions, and use their musk in potion making.
    • Hidden Fragrance, a unicorn in several universes, has a skunk theme to her and has scents as her special talent, so she can use spells to make horrible smells. Don't compare her to one though.
    • The Tales 7 and Twilight discover a version of the Tales universe where the seven are Digidestined. Sweetheart's partner, Mephitimon, is a skunk based Digimon, and digivolves into Sukankumon, a bigger skunk themed Digimon. As the latter, her Musk Jet attack fires a jet of horrid smelling mist, and can be fired from the expected spot or her mouth to stun and disorient opponents with the stench. Ironically, her Ultimate form has a sweet smelling healing version in addition to the other one and an acid attack. Her Mega is a 100 foot tall skunk. As with the other examples, it's surprisingly useful and effective.
  • So Last Season:
    • The Storm King's Obsidian Orbs are a lot less of a Story-Breaker Power than they were in canon, as Rainbow Dash's reaction time and speed have both increased enough that she's able to take Tempest off guard and make her waste them. Fortunately for the Storm King, he's increased his army's threat level sufficiently that he's no longer reliant on them.
    • A 'baseline' Equestria can run into this when faced with a multiverse tier threat, as while Mainline Equestria has gotten much stronger others weren't so fortunate. Even the invading Flim Flam Brothers, relative small-fry on a multiversal scale, were capable of conquering multiple such Equestrias before Mugging the Monster when they invaded Mainline Equestria.
  • Space Elevator: Construction on one began in Ponyland, and forms a minor background arc for quite some time before finally being completed.
  • Stop Being Stereotypical: Ember and Mina don't get along due to their different views of how dragons should act. Both of them agree that Garble's behavior isn't it, seeing him as every dragon stereotype bundled into one person. Spike agrees with them. Given in canon, when Garble convinced Spike that all dragons were like him, they have a point.
  • Story Arc: In addition to stand-alone Jaunts, there are several story arcs of various lengths detailing longer adventures and events:
    • "Magenta Diamond" - the jaunting Mane Six discover an alternate Equestria linked to another world populated by humans and protected by a trio of magical alien guardians called the Crystal Gems. When the true heritage of this Equestria's Diamond Tiara came to light, it attracts unwanted attention of a resurrected crystalline tyrant from Equestria's past. Crossover with Steven Universe
    • "My Little Pony Tales" - a classic First Contact story whereupon the Mane Six arrived at a world in midst of the Information Age, its ponies ignorant of magic but possessing more advanced technology. Starting with meeting seven pony girls in the woods on camping, the Mane Six begin a series of events that would change that world forever. As title implies, a crossover with My Little Pony Tales, and introduces Ponyland of the late G1 MLP era to the Jaunts.
    • "Gods' War" - The jaunting Mane Six found themselves in a universe where battles between kaijus from the ancient past had brought Equestria to its knees, just as a new and terrible threat emerges that even Equestria's powerful kaiju 'guardian' might not hope to defeat. Crossover with the Godzilla franchise, specifically with the Legendary Godzilla setting.
      • Spawns several more sequels/side-stories one-shots and arcs: "Gods and Guardians", set in an alternate 'Gods' War' timeline where preparations made by the ruler of a previously-lost civilization changed the course of events before and during the original story. "Gods' War: Reflected" retells the story with the Daring Do and the Wonderbolts Jaunting team in the Mirror Equestria of IDW's 'Reflections' arc, where heroic kaijus are the villains and vice versa.
    • "Lightning the Darkness" - The jaunting Mane Six found themselves in a world where downtrodden Earth-Ponies are oppressed by the Demon Lord Yomi, who had taken over and turned the planet into a dystopic Villain World with its demon minions and empowered evil mortal warlocks and witches. Finding themselves becoming an Outside-Context Problem for the warlocks and demons with their arcane powers, it is up to the Mane Six to help the local Resistance rediscover magic and help them take back the world from Yomi's darkness.
    • "Bright Future" - the Mane Six explores an alternate future Equestria that has essentially become a Utopia, populated by future Alicorn versions of ponies they know and filled with high-tech and high-magical wonders. What would a glorious future where the heroes had won and peace and harmony had prevailed hold for the Mane Six to discover? Introduces Bright Future Equestria to the Jaunts.
    • "(Title Deleted From All Records)" - In the grim darkness of an alternate far future, war rages across the stars as the determined races of Equus fought to stay alive in a galaxy full of horrors and rediscover their glorious past to rebuild their shattered future. The Mane Six found themselves stumbling right at the heart of their galaxy-spanning empire and discover a universe where legions of super-soldiers led by trans-equine demigods fought to reclaim the stars for Ponykind, all led by an immortal Empress with a mysterious past and many secrets to reveal. A Fusion Fic between Equestria and the Warhammer 40,000 universe, that introduces the Harmonion Hegemony to the Jaunts.
    • "Invasion" - An older, alternate Starlight Glimmer from one of the dystopian world-lines created during the events of 'The Cutie Re-Mark' by Starlight's revenge spell comes to Mainline Equestria to warn them of an impending invasion - from of all worlds, the one where the Flim-Flam Brothers had taken over their Equestria, and now seeks to add Mainline Equestria to those worlds under their control. As Mainline Equestria and the rest of the Multiverse Alliance gears up for war, the evil Ispita complicates matters as she pursues her own agenda...
    • "Eye of the Storm" - in this sequel to the "Invasion" Arc, the events of the MLP movie are derailed as the Storm King's rampage and plans are discovered early, and Equestria and her allies prepare to stop him before he could succeed in his world-conquering scheme. But as they discovered, the Storm King had not been idle after the Flim-Flam Brothers' invasion, and had been empowering himself with the tech salvaged from the earlier war. Mainline Equestria's fate hangs in the balance as the forces of the Alliance and a much more dangerous Storm King face off...
  • Sufficiently Advanced Bamboo Technology: The 'Hidden Ones' in the Tales verse (Pegasi, Unicorns, Flutterponies, and Sea Ponies) all have advanced magic that makes them even to the pre-jaunting Ponyland's technology. This takes the form of more primitive looking tech such as bow and arrows or tribal weapons, but are every bit as powerful as Ponyland's military tech before the Jaunting.
  • Super Cop:
    • The purpose of both the Mass Production model of the Paladin Armor and the Law Enforcement variant of it. The former is for the Royal Guard and the latter is for police usage, both drastically increasing the power of the user. While already competent in their work, the armor makes them a nightmare for criminals and lets them quickly wipe out several criminal syndicates.
    • The RANGER Squad from Ponyland is this, being a SWAT Team equipped with their own counterpart to the Paladin Armor and lead by Sincere Heart, who uses the Super Prototype model.
    • Metal Twilight becomes a Royal Guard post Heel–Face Turn.
    • The Multiverse Police Department, another multiversal alliance eventually met, are this, being powered up police chasing multiversal threats. First Contact with the Alliance upgrades them further with the Paladin Armor and other advances, while also benefiting the Alliance with their own advances and manpower.
  • Super-Empowering: The Mane Six discover that using their Rainbow Powers in certain worlds that didn't already have Elements of Harmony in proximity to ponies they've made friends with there can result in a repeat of what happened to the Humane Five. This results in the Tales Seven getting Rainbow Power forms of their own and having their Earth Pony magic awakened during the concert at the end of the arc.
  • Super Fic: Some of the universes the Mane Six arrive in are this, including ones where the CMC are Toku heroes, a world where various characters are Kamen Rider heroes, and so on. Ironically Equus Prime is this to several worlds where the population lack any form of magic, such as the Lighting the Darkness Arc. After the accidental Super-Empowering, the Tales world could be considered this, as the Tales Seven get full Earth Pony magic and Rainbow Power forms.
  • Superman Stays Out of Gotham: Subverted often and Justified: the heroes of different universes will pitch in and help out other universes when they can, but the issue of rebound time between Jaunts makes calling someone in to help has to be both set up ahead of time on both ends and be timed with dimensional barrier being ready for another dimensional portal to be opened. As such, in a time sensitive situations, the native heroes will likely have to deal with the problem without outside help that wasn't already present visiting in their world because there simply isn't time for reinforcements to be summoned.
  • Super Mode:
    • The Mane Six still have their Rainbow Power forms, which they use to hold off Bagan, and get some help from Sunset Shimmer learning how to use magic and 'pony up' in worlds where they're not ponies.
    • Amicitia and the native Twilight use the power of the Elements to restore Gojira after he was mortally wounded by Bagan. This results in him not only being revitalized, but turning into Super Godzilla.
    • The Tales main seven end up accidentally getting Rainbow Power forms via Super-Empowering from the mane six, though like the Equestria Girls cast they have no idea how the powers work.
    • As in The Bridge, the Guardian Beasts can be powered up enough to temporarily obtain their true power and become much stronger. Twilight has the Alliance's forces converge all their fire and heat based weaponry on Rodan to power him up to it to turn the tide against the Storm King's ultimate weapon Zeus.
    • Seiryu, the Equestrian's Magitek Mechagodzilla, has a 'Harmony Empowerment System' designed to channel the Elements/Rainbow Powers. When activated, its Tron Lines turn rainbow colored and it gets a huge power up. This was based off the Super Godzilla above, which is the same Godzilla Seiryu was based off of.
    • The RANGER V2 suit, the upgraded model of the RANGER armor, has a Riot Mode that increases its performance, gives it better weaponry, and provides better armor. The drawback is it can only be activated once the solar panels on the suit are fully charged, and it's currently only in the prototype stage.
  • Super Prototype: Shining Armor in the "Paladins of Harmony" universe uses a prototype, Metal Heroes inspired suit of armor, which is far superior to the mass production version the guard uses. Justified, as the prototype's magic cost was far too high for a normal pony to actually use for more than five minutes at a time and Shining can only use it practically because he's got abnormally high magic reserves. The mass production version is also far cheaper to produce, and the version chosen by the jaunting Equus for their average jaunters to use for protection and exploration purposes, with only those who can handle the advanced model receiving it.
  • "Super Sentai" Stance: Invoked when the Toku themed universes team up. They realize that during team ups this is accompanied by a large explosion behind them...so they turn around for the final moment and hit the enemy with the explosion.
  • Super-Soldier: The Hegemony has the Space Legionnaires, genetically and cybernetically enhanced warriors who qualifies as these. Unsurprising, given they are expies of the Astartes.
  • Surrounded by Idiots: Shining Armor visits a version of Equestria where the royal guard are actually as incompetent as everyone makes them out to be. The native Shining Armor is actually genuinely competent, and thus feels this way.
  • Talking the Monster to Death: Cheerilee manages to talk down Garden!Cheerilee by filling her justification for her attempted murders full of holes. She accomplishes this by being from the future from the evil Cheerilee's perspective, and thus able to show her exactly what her 'weeds' even up becoming down the line in a few years.
  • Team Shot: While a literary medium, this is the imagery invoked when the Tales Seven and Twilight line up with the Digidestined Seven as the former transform into Paladin Armor and the latter have their partners Digivolve.
  • Teeth-Clenched Teamwork: Downplayed, but present. The various worlds contacted and united by Mainline Equestria all work together rather well as allies, but differences in various issues due to divergent cultures, ideologies and moral standards has led to disagreements and tension among the members of the Multiverse Alliance. Luckily this has not led to serious internal conflict (Yet), and the G2 world brought in a legendary figure respected enough by most to serve as a mediator.
  • Theme Naming: The Powered Armor suits are all named after Dungeons & Dragons classes. The default version is called the Paladin Armor, the Ponyland version is called the RANGER Armor, the G3 universe version is called Bard, Shadow Web's Evil Knockoff version is called Blackguard, and Pyromancer for the Fire Pony's version.
  • There Are No Therapists: Subverted; the jaunters find Psychotherapist Equestria, which is a universe where everyone in Equestria is a licensed therapist. Garden!Cheerilee was sent here after her defeat for treatment among other things.
  • This Cannot Be!:
    • Yomi's warlocks in the Lighting the Darkness Arc have this reaction when the mane six manage to harm and overpower them, as they're used to being Invincible Villains who can't be harmed.
    • Bagan has this reaction when Super Gojira overpowers and ultimately kills him.
  • Thou Shall Not Kill:
    • The Mane Six have this mentality, but have gone to several worlds were killing someone genuinely evil is considered less morally wrong. Most of the time, the Mane Six compromise and don't kill, but don't exactly condemn the natives of that world for doing so if they've got understandable reasons (such as the Lighting the Darkness world, where the rebellion have only managed to stop any of Yomi's forces with lethal force due to the power gap).
    • The Tales Seven as well, seeing themselves as superheroes whose gifts and abilities obligate them not to take lives. Notably, they don't object to allies killing in self-defense; fighting alongside Hegemony forces during the Winter Wedding arc.
    Patch: "Let the soldiers kill. We're heroes; we save people."
    • The Digidestined 7 play with this trope. They're willing to kill Digimon, but only because they have Resurrective Immortality and thus aren't actually Killed Off for Real, rather they reincarnate as Digi-Eggs. They absolutely will not kill one and not open the portal for their data to return to the Digital World, which would be permanent, and won't even do that to as someone as vile as Huntermon.
  • Tower of Babel:
    • Mentioned implicitly early on in the 'Tower Beyond The Sky' Arc by Patch as the story of The Great Tower, which is Ponyland!Equus' version of the myth. Like in the original tale, Ponykind of yore tried to build a city with a tower that would reach the heavens itself, and nearly succeeded, until the divines struck it down as punishment of Ponykind's 'hubris', leaving Ponykind scattered and bitterly divided. Both Patch and Bright Eyes debate about the meaning and validity of the story's cautionary moral about unchecked pride and progress as well as the power of unity, while ominous comparison is made between the Great Tower and Ponyland's Space Elevator - the 'tower beyond the sky' of the story - foreshadowing trouble later in the arc.
    • Patch optimistically believed that everything will turn out alright with their Space Elevator, unlike the Great Tower, pointing out that where Ponykind in the story failed, they succeeded. Only time will tell...
  • Transformation Sequence: Several characters from different universes have them. Generally it is of the 'actually instant but slowed down for the audience' variety. Pinkie Pie, being Pinkie Pie, can produce a television from Hammerspace and show the slowed down version for her friends.
  • Transformation Is a Free Action:
    • Many heroes transform and Paladin Armor becomes a staple of the Alliance's equipment load out, but it's Justified as the transformation is nearly instant and if shown to the audience is a slowed down version. The Paladin Armor in particular only takes a few seconds.
    • Justified during a Fusion Dance as well once the armor is upgraded properly: the Fusion Dance takes time, so the armor rotates around them while generating a powerful energy barrier to protect them during it. The space mode's barrier is even customized to protect its users in space.
  • Under the Sea: The Deep Blue Sea Arc is set on a version of Equus that's completely covered in water and life evolved different as a result, with the mane six turned into different varieties of mermare.
  • Utopia: The Bright Futures world takes place in a potential future where the natives have all became divine, immortal beings, poverty, hunger, and so on are things of the past (reached in entirely moral ways), and everyone is happy. They've also developed a cosmic spanning civilization with peaceful relations with other species throughout the universe.
  • Vagueness Is Coming: Several characters warn the Alliance that things are lurking out there in the multiverse that are far stronger and more dangerous than the things they've fought up to this point, and the Alliance is on a collision course with them they may not be ready for yet. One of them is Ispita, one of the most dangerous threats in their corner of the multiverse.
  • Villain Forgot to Level Grind: Subverted: one big thing is while the heroes are leagues stronger than in canon due to the jaunting, that technology and magic doesn't stay solely theirs. Both organized crime and main villains begin to get a hold of it, and several story arcs deal with the consequences of this. There's also the multiverse tier versions of the major villains such as the Court of Love, 13 Shadows, and Heralds of Eternal Night who have level grinded a lot by jaunting on their own.
  • Villainous Breakdown: Bagan has one as Super Gojira manages to overpower him and he realizes he severely underestimated Harmony's power.
  • Villain Pedigree: Any villain who either acquires jaunting tech (directly or indirectly) or is a multiverse tier threat becomes far more powerful and dangerous than their baseline counterparts. Justified in both cases, as the former are gaining strength in the same way as the heroes have and the latter are typically from universes where they won and continued to increase in strength instead of simply being stopped in their tracks by the heroes, making them essentially Future Badass versions of their baseline selves.
  • Villain Song:
  • Villain World: A few of the alternate worlds have been taken over by villains. While there's naturally the canon ones, there's also ones ruled by original villains.
    • A universe they arrive at initially looks like it's ruled by Starlight Glimmer but is actually ruled by an evil adult version Apple Bloom with the same mentality as her.
    • The world ruled by Lord Yomi is a Dystopia were he and his witches and warlocks enslave everyone else.
  • Void Between the Worlds: Mentioned several times, with 10D Pinkie Pie's inn for Dimensional Travelers being placed here. It's also where Ispita's HQ is located, which makes it very hard to find.

    W to Z 
  • We Have Reserves: Remarkably subverted on multiple occasions, considering those present.
    • In theory, the Multiverse Alliance, by virtue of its sheer, ever-growing size, has enough soldiers, heroes, researchers, inventors, mages, vehicles, monsters, gods and whatever else to throw at any conceivable problem it could face. In practice, problems with transportation (Due to recharge and membrane rebound period) and resources/people being spread thin meant they are usually prevented from bringing it to bear, at least until a climatic moment.
    • Some of the Alliance's more powerful members possesses ENORMOUS reserves of resources and population by virtue of their sheer scale. The aforementioned Hegemony, for example, is a galaxy-spanning empire from an alternate far future that is constantly expanding and at war with various hostiles and horrors of their universe, which leaves them with massive military forces which they could use to help garrison and fortify an entire continent and still allow for deployments elsewhere across the planet. Disturbingly, they are not afraid to spend them like currency to achieve an objective, owing to their hardline and ruthless temperament.
    • Other members like the Intergalactic Federation of Friendship (from the 'Bright Future' Equestria world-line) is capable of this, but refrained by choice to avoid making the Alliance too dependent on them. Their modus operandi is to provide token but still critical aid to the Alliance, usually just enough to help other members solve the problem at hoof.
  • Wham Episode:
    • Jaunt 23.10: the travelling six meet Lady Babylon, the first evil jaunter from another world they've encountered.
    • Jaunt 36.7: The Discord Continuum, a group of benevolent (or neutral) Discords makes contact with the Mane Six, and gives them a look at several other big threats roaming the Multiverse and the scope of their threat.
    • Jaunt 37.1: The mainline Storm King has managed to salvage enough of the Flim Flam Brothers technology to power up himself and his army by a huge margin.
    • Jaunt 43.4: Ispita reveals her true endgame. Namely, mutating herself into a Nexus of Black Magic.
  • Wicked Witch:
    • Walpurgis Night, one of the villains of the Magenta Diamonds Arc, is this.
    • Lord Yomi has witches as his female minions.
  • Wound That Will Not Heal: After becoming Super Gojira thanks to the power of the Elements, Gojira is able to inflict these on Bagan due to the petrifying effect of the Elements forming stone at the edges of the wounds.
  • You Are Not Ready: Mainline Equestria is warned of this by both Ispita and the Discord Continuum in regards to bigger threats lurking out in the multiverse. Specifically the Court of Love, Heralds of Eternal Night, and 13 Shadows.
  • You Have GOT to Be Kidding Me!: Rainbow Dash has this reaction to the group arriving in a world where the only difference is that everyone is non-talking, non-anthropomorphic cats.
