Fanfic / The Bridge

http://static.tvtropes.org/pmwiki/pub/images/bridgenewcover.png
Matter cannot be created nor destroyed, only moved, displaced, changed into energy; or morphed into a new state....All four just happened...

In the heart of the Pacific Ocean, an all out invasion-turned gang-war occurred without warning between the two largest factions of the planet's kaiju population. As all hell is breaking loose on Solgell Island, the Global Defense Force see an opportunity to test a new superweapon, trying to rid the world of some of mankind's biggest threats while they are all clustered together. As the faction leaders unleashed their most devastating attacks, Dimension Tide fired and the combined energy seemed to erase some of the factions' power players off the map.

But, as the world cheered or bowed their heads in loss, none of them took a moment to realize Dimension Tide's blast, long believed to be an artificial black hole; behaved nothing like what theoretical physicists believed it should.

Six of the most powerful beings on the planet weren't crushed, imprisoned, or vaporized; they were moved.

Moved, changed, shrunk; but still very much alive. Equestria just got six new denizens just as a horror from the kaiju home realm sets its sights on Harmony's world.


The Bridge is a crossover fanfic written by Tarbtano, illustrated by Faith-Wolff (with some additional illustrations by Pyrus-Leonidas), contributed by Skylark8756, and proofread by Faith-Wolff and Lance Omikron, combining My Little Pony: Friendship Is Magic, Godzilla, Gamera, Pacific Rim, and a few other Kaiju franchises. Timeline-wise, it begins some time after the events of "Inspiration Manifestation". The fanfic is currently in progress (latest chapter posted as of 11/28/2016), marked as incomplete currently with forty two chapters (34 normal chapters note , 9 bonus chapters, and a One-shot) and one Q&A section published.

Readable here, though the story is still on-going and not yet complete. Tarbtano also has a YouTube account that he uses to release trailers, promos, and such.

A midquel called The Bridge: Sound of Thunder, made by the same team; details the story of another kaiju transported to Equestria named Raiga. It is now complete.

A midquel/spin-off from the same team has also been released, which will involve a small scale crossover between The Bridge and another My Little Pony fanon universe, The Shimmerverse. It is called The Bridge: A Shimmer in the Dark.

A one-shot from the same team called The Bridge: Phoenix Night details a friendship between Rodan and Phoenix Flamez, a character created by FallenAngel5414.

A spin-off by BlazingPhoenix17 called The Bridge: Humanity's Stand shows what is happening in the Kaiju's world, Terra, while this is going on.

A Recursive Fanfiction (in which Tarbtano gave the author special permission to use his versions of the characters) called Godzilla Junior's Secret focuses on a romance between Godzilla Junior and Princess Luna.

A Recursive Fanfiction called The Alpha Predator and The Element of Kindness is a non-canon one-shot about a romance between Fluttershy and Gojira.

This Fan Fic provides examples of:

    open/close all folders 

    Tropes A - M 
  • 100% Adoration Rating: Princess Celestia, as per canon and role as the Equestrian Big Good. Princess Luna and Cadance aren't far behind.
  • A Day in the Limelight: "Sound of Thunder" largely acts as this for Raiga. Being a non-Toho kaiju from a well made, but still small time film; she was virtually unknown by the fandom. Multiple readers at first mistook her for an original character.
  • Action Girl: Any of the female kaiju note , Rainbow Dash, any of the female royal guards, and the alicorn princesses.
  • Adaptational Badass:
    • While Bagan is certainly powerful in the unmade films he would have been in, his power in his last attempted canon introduction put him roughly on par with Destroyah and Burning Godzilla. Here, he is undoubtedly the strongest kaiju of all time.
    • Many of the My Little Pony characters, particularly the alicorn princesses, got a similar treatment. While certainly powerful in her own right, Princess Cadance is able to go hoof to hoof against King Sombra in an upfront fight whereas in canon we've never seen her in a full on battle.
    • The Jaegers are also this, despite the Anteverse Kaiju being far outclassed. Due to Earth being much better at making mecha and various reverse engineered alien tech, they're a bit tougher than they were in canon. According to Word of God have fusion reactors instead of fission reactors and have Space Titanium in their construction among other things. The biggest bonus, however, is they're much more practical to make than their canon counterparts due to this.
    • Grogar in canon was very powerful and a Hero Killer as is, but in the Bridge? He's the nexus of dark magic itself and in the same tier as Bagan and Harmony.
  • Adaptation Expansion: Both sides get a good helping of this.
    • MLP: The origins and early years of Princess Celestia and Luna get more allusions and flashbacks then they have in canon. Additionally, we get more of an insight into the group dynamics for the siren trio and how their powers work.
    • Kaiju: Everyone due to the extended continuity and timeline, as well as speaking in dialogue we can actually understand now. What sort of morality Godzilla Junior grew up to have, the line of succession for the Mothra, getting to see Destroyah when she's not in Axe Crazy mode; etc. Monster X especially get this, due to his Diabolus ex Nihilo status in his movie giving us no insight into his backstory, personality, or dynamic between his forms, and making him a more fully fleshed character as a result.
  • Adaptational Heroism: Due to Alternate Character Interpretation on the author's part, numerous villainous kaiju were given more heroic/redeemable traits.
  • Adaptational Species Change: Baragon was a dinosaur in the films, but in The Bridge, he's been changed into a therapsid due to his mammalian features such as external ears.
  • Affectionate Nickname: Mothra Lea and Godzilla Junior are old friends, resulting in them calling each other Goji and Lele respectively. Alicorn sisters Princess Celestia and Princess Luna also get playfully called "Celly" and "Lulu" by the other.
  • All Part of the Show: In the human world, Photo Finish witnessed the battle against Enjin in the hospital, but she assumed a movie was being filmed.
  • All Your Base Are Belong to Us:
    • The gyaos flock attacking Canterlot.
    • Bagan setting a trap to attack the Big Good, Harmony, directly and invading the ascension realm inside the Tree of Harmony. He's unable to defeat her, though does succeed in cutting her off from Equestria for a time.
  • Alternate Continuity:
    • The author combined several different continuities to create the universe that the kaiju in this story hail from, which he's dubbed the Amalgam Universe. It uses the Heisei Godzilla series as the base, but neatly ties in the Rebirth of Mothra trilogy, Pacific Rim, most of the Millennium age Godzilla series, the Legendary Pictures reboot, the Heisei Gamera series; and numerous single-movie kaiju names both from Toho and other companies. There's plenty of continuity mixing between franchises as well, with some changes that still make a lot of sense (for instance, Gamera is retooled into a Guardian Monster from Godzilla, Mothra, King Ghidorah: Giant Monsters All-Out Attack!, replacing Mothra, who already existed). The full timeline is viewable here.
    • On the MLP side, the story takes place during the show's run with the kaiju entering Equestria midway through Season 4.
  • Always a Bigger Fish:
    • Garble and his gang of teenage dragon bullies terrorize a pony camp until they are interrupted by the larger and more powerful Anguirus.
    • The Anteverse kaiju ended up running into this, as they had not only the Jaegers to deal with but Kiryu, other reconstructed UN robots, and the heroic kaiju as well. Trespasser ended up ticking Junior off and got destroyed. Multavore had the misfortune of being killed the moment she entered the universe, resulting in Junior wrecking the Precursor's production facility on the other side.
  • An Arm and a Leg: Hyper Gyaos used her beam to slice off Gaira's hand when he tried to ambush her.
  • Apocalypse Maiden: It turns out the Alicorns are this in a sense: Grogar was imprisoned by Harmony and while she naturally is not going to willingly release him, Alicorn Magic will work just as well to break his seal and other than Harmony seems to be the only thing that can.
  • April Fools' Day: The "March 32nd" special involving a dimension hopping Sonata Dusk, Megalon, and Pinkie Pie as instructed by Discord. The Silliness Switch is cranked Up to Eleven.
  • Apologetic Attacker: Monster X to Kaizer Ghidorah when they have a Battle in the Center of the Mind after Kaizer tried to seize control of their body. With Aria Blaze's help, X is able to force him back into a mental prison. But after seeing glimpses of Kaizer's memories and the life he was trying to avenge, X whispers "I'm sorry." before Kaizer is sealed away, for awhile...
  • Armor Is Useless: Completely averted. Where the armor various Equestrian characters are wearing saves them from being injured far more than if they weren't wearing it. It may not be enough to negate the attack entirely, but it does work.
    • The aversion is evoked in Princess Cadance's actions, where she takes a moment before jumping into the fray to put on some plate mail.
    • Monster X's bone armor and helmet saved him from multiple would-be killing blows from the more physically powerful Enjin.
  • Arc Villain: While the story has a central Big Bad, each story arc has a defined villain after the status quo is established.
    • Everfree and Canterlot Attacks: Gyaos Horde
    • Crystal Empire Arc: King Sombra
    • Human World Arc: Enjin
  • Art Shift: The illustrations taking place back in the kaiju's home dimension tend to be more detailed with black used for the outlines, to make the setting a little more realistic. For ones taking place in any of the Equestriam realms however, the detail is relaxed and colored outlines are used to fit the show's art style.
  • Artificial Equestrian: It's heavily implied Princess Celestia and Princess Luna were created by the Tree of Harmony, because they were found as foals in front of it with no parents.
  • Asskicking Equals Authority: How the Mutations work, strongest one leads. Xenilla is their leader simply because he's too powerful for any of them to challenge 1-on-1 and potentially win. Destroyah's the only member that could potentially beat him and she's loyal to him. Best shown by what happens the moment he and Destroyah are presumed dead after being hit with Dimension Tide's black hole: the rest of the faction instantly begin plotting to take over the fraction for themselves now that the two top dogs are both gone.
  • Attack Backfire: Destroyah has a division ability that, when in full kaiju form, allows her to go from a single 120 meter tall monster to a dozen or so smaller monsters and swarm. When she tries to do this in her pegasus body, it results in her turning into a bunch of toddlers.
  • Attack Its Weak Point: Grand King Ghidorah is durable enough that nothing Irys, Megalon, Gigan can throw at him does more than knock a few scales off. They only manage to damage him after Irys cleaves off a line of scales as Megalon distracts Ghidorah, giving Gigan enough time to build enough momentum to hit the bare patch Irys cleared; cutting in deep enough to actually hurt Ghidorah.
  • Attack of the 50-Foot Whatever: Since this is a crossover with Godzilla, this trope is most definitely a thing that happens.
    • The first examples we get in Equestria feature both villainous and heroic versions (right after each other no less!). Garble and his gang experience greed growth and rapidly change into full size dragons. Cue an injured Rainbow Dash inadvertently causing Anguirus to revert to his true form to save the day.
  • Audience? What Audience?: Aria Blaze doesn't understand when Sonata Dusk breaks the fourth wall. Later, Gigan doesn't know what Megalon and Mane-iac are doing when they break the fourth wall. However, Gigan is briefly able to see the fourth wall and is horrified. Later, Rainbow Dash and Pinkie Pie don't know what Discord is doing when he breaks the fourth wall.
  • Aura Vision: An advanced alicorn spell to detect disguises. It's what shows Luna and Celestia what the Kaiju-Converts gathered really are. It also shows the magical potential or affiliation somepony has. The Mane 6 all have a brighter than average aura in the color of their respective Element of Harmony, Princess Cadance has a very bright, glimmering aura indicative of the Crystal Heart; and Celestia and Luna have blazing bright auras that contain sparks of their old Element ties.
  • Author Appeal:
    • The Sirens' loving description of the sea comes from the fact Tarbtano lived almost his entire life near the ocean, despite ironically being born in a desert.
    • The scarf Monster X wears over his mouth in his human form is partly based on the fact Faith-Wolff likes Kakashi from Naruto.
  • Authority Equals Asskicking: Princesses of Equestria, Luna and Celestia on the Equestrian side; and King of the Monsters, Godzilla on the Kaiju side.
  • Bad Dreams: Mothra is plagued by them because thanks to Genetic Memory she knows how it looked and felt when Godzilla Senior tore her father's throat out. She sometimes gets nightmarish flashbacks from Battra's POV whenever she looks at Junior or Xenilla. Just look at them!
  • Badass Crew: Irys, Gigan, and Megalon form one, managing to put up one hell of a fight against Grand King Ghidorah, actually managing to damage him.
  • Badass Family:
    • The Godzilla "Dynasty" is an unofficial example. The start was the original Godzilla now reborn as Kiryu being the grandfather, then his even more powerful son, Godzilla Senior. Senior then, by two cases of outside forces using his cells and then by adoption, "fathered" Biollante, Xenilla, and Godzilla Junior.
    • The Sentry family line contains some of the most decorated and legendary stallions and mares in the history of Equestria's guards and law enforcement. Played straight with Stalwart Sentry, but subverted with his son Flash Sentry. Flash clearly has the heart for heroics, just not the opportunity yet.
    • The Royal sister's family and family by choice. Princess Celestia and Luna are the most powerful of the ponies, and Celestia's honorary niece Cadance is no slouch either. Starswirl the Bearded served as the two's adoptive father and they were also raised by Equestria's original founders.
  • Badass Princess:
    • Crash through her roof, beat down half her and her sister's guards; and you'll soon be questioning why Princess Luna even needed guards in the first place. She actually managed to knock out the ponified Godzilla before fainting from her injuries.
    • Celestia is even stronger than that. 1,000 years more experience and a proximity based power boost from Luna give you enough strength to floor six fighting Kaiju-Ponies in one burst.
    • Cadance shows this herself, personally fighting Sombra alongside Xenilla.
    • Twilight Sparkle defended the Tree of Harmony admirably and even slew some of the Gyaos.
  • Bad Future: A future version of Flurry Heart apparently comes from one where Bagan and Grogar are apparently both released and ruined the universes and killed several characters including her parents, though seemed to have been stopped from totally destroying them. Her goal is to use her brief window to change the past to make things right.
  • Balls of Steel: Enjin is unaffected by Sonata's nutshot attempt.
  • Battle in the Center of the Mind: Monster X gets into one with Kaizer Ghidorah for the right to control their body. With Aria Blaze's help, X wins.
  • Battle in the Rain:
    • The fic begins with one between Godzilla Junior and Xenilla.
    • Hyper Gyaos vs. the rest of her flock.
  • Beam-O-War:
    • Godzilla and Xenilla were charging up for one when Dimension Tide hit.
    • In Sound of Thunder, Raiga and Mirror Godzilla's battle climaxes with one of these with both characters using their respective ultimate attacks. The result is ultimately their combined attacks detonating but with Raiga managing to force the struggle in her favour far enough that Mirror Godzilla took the brunt of the blast.
  • Beauty Is Never Tarnished:
    • Completely averted in Luna's fight with Godzilla. Over the course of the battle, the princess suffers a multitude of heavy and extremely visible injuries. She recovered eventually, but is still in bandages for a few chapters. To be fair, she roughed up Junior just as badly.
    • Subverted with Blade Dancer, another Equestrian beauty, when she gets slashed across the face with a spear. It looks nasty at first, but Xenilla uses a healing crystal on her to mend the wound.
  • Because You Were Nice to Me: Xenilla does make due on a promise Blade Dancer makes him swear on to save Princess Cadance's life from King Sombra), after she frees him from his imprisonment. He even laments that it's the first time anyone has tried to do something directly for his benefit before. However, once freed, his way of showing gratitude is a tad unorthodox. He throws her into his prison cell and locks it before leaving, rationalizing she'd be safe from the coming battle in there.
  • Behemoth Battle: Considering half the roster have true forms over 80 meters tall, this is a given.
  • Benevolent Boss:
    • Villainous example. The Big Bad gets the loyalty of numerous evil kaiju not only by a show of force, but by offering and giving them exactly what they wanted most. Most pledged their service without hesitation. However, it's ultimately a facade to keep their loyalty, Bagan is an Omnicidal Maniac planning to destroy all life, including them, but needs their help regaining his full power before that.
    • On the positive side, Godzilla junior is considered the 'king' of the terran kaiju, who follow him out of well-earned loyalty and respect. He and his highest ranking subordinates are genuine friends. Likewise Princess Luna and Celestia are well respected in Equestria and care greatly for their subject's well being.
  • Benevolent Precursors: The creators of the Guardian Beasts, who did so to stop Bagan when he returns, even though it'd be over one hundred thousand years in the future. Even moreso with the reveal that the Fae who were involved in this were essentially performing a Heroic Sacrifice to do so.
  • Beware the Nice Ones: Xenilla comes to the conclusion, within a short time of arriving, that Equestria as a whole is this trope. He's not wrong.
  • Bilingual Bonus: Several. Most notably the titles of several chapters Unbekannte Soldat (German for Unknown Soldier) and Henkōten (Japanese for Changes)
  • Big Bad: Many readers at first assumed Xenilla and Destroyah were the main villains of the story. Then when Red was introduced a lot of them thought he would be the main villain. Turns out it's the being haunting Xenilla's nightmares and defeated Red before taking over Zenith. Eventually, it's revealed to be Bagan. However, it seems that Grogar, the Shadow King, is being built up as another Big Bad.
  • Big Bad Ensemble: Bagan and Grogar seem to be one, given Empress Flurry Heart contributes her Bad Future to both of them and they're implied to be on the same tier.
    Tarbtano': For a crossover this big, you thought I'd settle for one Big Bad?
  • Big Brother Instinct: Do not, under any circumstances threaten to kill Godzilla Junior in front of Xenilla.
  • Big Damn Heroes:
    • During the opening fight, Mothra and Anguirus do this for each other while fighting Destroyah.
    • Anguirus transforming to save the campground from Garble and his dragons.
    • Godzilla Junior transforming to fight off the gyaos horde converging on Canterlot.
    • Xenilla tackling King Sombra out a window before he can stab Princess Cadance. She then armors up and flies into the fray to return the favor.
    • Even more than a few Anti-Villain characters get these. Aria Blaze transforming into her Super Mode and unloading on Enjin to save human!Monster X. And then kaiju!Monster X bursting out of a lake to save Adagio Dazzle and Sonata Dusk from the similarly transformed Enjin.
  • Big Good:
    • As stated below (see Take That), Princess Celestia is not the 'Tyrantestia' seen in some other fanfics. Here she is a beloved ruler who will do whatever she can to protect her subjects. Helps she is more than strong enough to floor the kaiju-ponies with a magic burst when enraged. note 
    • Then there's the entity who brought King Caesar to Equestria long ago to fight Tirek, and has been providing advice and aid to both the ponies and some of the less evil kaiju since the story started. It turns out to be Harmony, an avatar of the Tree of Harmony. At one point in the past, she also defeated Grogar and sealed him away, as well as provided help to defeat his students.
  • Bittersweet Ending: "Sound of Thunder" has one. Raiga and Mirror!Starlight Glimmer, along with some help from Mirror!Lightning Dust and Manehattan successfully fend off an assault from Mirror!Godzilla long enough for the city to evacuate. Mirror!Xenilla and Destroyah arrive to save them from Godzilla, but just before they can finish him off he is teleported to safety by Cadenza's crystal; meaning he'll be back.
  • Black and White Morality / White and Grey Morality: While the core group of heroes and heroines from both sides are benevolent, the morality of the villains is all over the place. Some like Irys and Monster X have redeeming qualities, others like King Sombra and King Ghidorah are completely evil. Then there's Bagan, who's an Omnicidal Maniac, but convinced himself his actions aren't evil.
  • Blasphemous Boast: Kaizer Ghidorah completely denies Grand King Ghidorah's claims to godhood, while declaring himself the inversion.
    Kaizer Ghidorah: "You are no god, but I am the Devil."
  • Blinding Camera Flash: Photo Finish subjects Irys to several.
  • Blue and Orange Morality: Xenilla is a very tough nut to crack. He is completely honest, but can be brutally blunt with his words. He shows great dislike for both love and hatred, seeing them as controlling emotions; but at the same time he's far from stoic.
  • Breaking the Bonds:
    • Godzilla Junior and Xenilla both humor their guards when they get arrested at different points in the story, then casually break their shackles.
    • King Sombra shackles Princess Cadance with crystal constructs and boasts that even with her Alicorn strength, she won't be able to break free in time before he kills her. Xenilla arrives in time to tackle him away before he can stab her, then while the two are fighting, Cadance manages to break them.
    • Harmony wraps Bagan with a chain that becomes stronger the more evil the prisoner is. Bagan is able to break it, possibly because he considers himself Above Good and Evil.
  • Breaking the Fourth Wall:
    • Sonata Dusk is aware she's in a story, referencing the author and the story reader's favorite activity.
    • During the Valentine Day's special, both Megalon and Mane-iac do this, pointing out that the dimension they're currently in is a comic book.
    • When Discord shows up during the baby Destroyah outbreak, he uses a Kindle-Fire to check Tohokingdom and This Very Wiki for information on what's happening.
    • The non-canon" April Fools' Day special occurs when Megalon, Pinkie Pie, and Sonata Dusk all broke the fourth wall at the exact same time and end up beyond the barrier together. Discord is also there as the fourth wall's "moderator". Gen 3 Pinkie Pie is also a 'breaker' and helps them out in their quest.
  • Breather Episode: Rodan and Rainbow Dash's ongoing story arc with the Neighagra Falls airshow largely could count as one as much like a slice of life episode from MLP, it doesn't have a villain trying to cause mayhem like the Gyaos, Sombra, and Enjin arcs; just a social obstacle to overcome.
  • Broken Masquerade: The Gyaos attack on Canterlot, and Godzilla's defense of it, ruins any chance Celestia had of keeping the kaiju presence in Equestria a secret.
  • Brooding Boy, Gentle Girl: In a non-romantic sense we get a surprising inversion with Monster X and Aria Blaze during their training together. Though both get their share of brooding, it's Aria doing most of it since Monster X is The Stoic most of the time. It turns romantic later one when the crisis has passed and X becomes Not So Stoic.
  • Bullying a Dragon:
    • Bold Rush repeatedly antagonizes Godzilla, even after it's clear his punches have no effect on him.
    • Grand King Ghidorah bullies Monster X despite knowing he can transform into the more powerful Kaizer Ghidorah.
  • The Bus Came Back: Many readers assumed the Sirens showing up in the Holiday special to be a one time deal and were surprised to see them return for a story arc taking place in the human world.
  • Came Back Strong: The 1954 Godzilla as Ghost Godzilla in the backstory due to being resurrected by the souls of the dead from WWII. To note, he's so powerful even Junior wouldn't have been a match for him alone and was as strong if not stronger as Grand King Ghidorah. It took Junior, Gamera, and Anguirus fighting him together to finally put him back down.
  • Canon Immigrant:
    • Hokmuto makes an appearance in the bonus chapter. The movie came out when the story was being written, and readers liked the character so much that Tarbtano gave him an extended cameo and fight scene.
    • Though it is a Massive Multiplayer Crossover in the kaiju home realm, Irys is the only member of the core Cast Herd who is not made by Toho. In this case her species, the Gyaos, are kaiju made by Daiei.
    • Several fan made MLP characters such as Blade Dancer, Captain Blueberry Frost, Key Ring, and Harmony have prominent roles in the story despite not being made by the author.
  • Car Fu: The sirens manage to stun the human sized Enjin by ramming into it with a van.
  • Car Skiing: The CMC plus Destroyah accidentally do this with their wagon while pursuing the Baby Des.
  • Children Raise You: Azusa was much more confident and brave after she raised Godzilla Junior.
  • Christmas Special: In a similar vein to the MLP realm jumping antics of the Halloween Special, Monster X and Irys (Hyper Gyaos) scout out the Equestria Girls realm, being temporarily turned into humans in the process.
  • Cliffhanger: Almost all of the chapters end on this to varying degrees, much to the joking ire of some readers.
    Tarbtano (when asked why): "Because I'm evil and the devil made me do it."
  • Clingy MacGuffin: A Siren's necklace can only be removed by its wearer. Not even Monster X is strong enough to remove Aria Blaze's necklace without her permission.
  • Combat Breakdown: Luna and Junior's fight. By the end, Luna only has use of one wing and can't fly while Junior is injured so badly he's not healing normally. Both are also battered and bloody. The final attack isn't even some big fancy move, just Luna bucking Junior really hard in the face.
  • Comes Great Responsibility: A root of Junior's motivations behind his heroics. In his eyes, because he has so much power, he's responsible for the safety of those weaker than himself, from threats they can't face but he can.
  • Comically Missing the Point: Godzilla Junior still fails to understand romance. Having seen both humans and Equestrians give flowers, the meaning flies completely over his head. Considering ponies are herbivores, he comes to the conclusion they are exchanging thanks by giving each other treats.
  • Composite Character: Several due to the combined timeline.
    • Junior is of course Godzilla Junior, but also fills the roles of all the Millennium Godzillas except GMK.
    • Anguirus is a combination of his Showa incarnation, his video game version, and his scraped GMK version, with some aspects of the reboot Gamera series added in.
    • Rodan and Raiga both have aspects of the Gamera reboot films like Anguirus.
    • Yonggary has the original's role as an ancient creature awakened from centuries of slumber, but his design seems to be closer to his reboot's, while also having aspects of the Gamera reboot as with Rodan, Raiga, and Angurius.
    • Bagan is an amalgam of his various unused concept selves and his video game incarnation.
    • Ghost Godzilla was the GMK Godzilla combined with the unused Godzilla vs Ghost Godzilla concept.
  • Continuity Nod: Even though this is a Massive Multiplayer Crossover, this is set after a largely unchanged Heisei series timeline with the grown up Godzilla Junior as the current Godzilla. This explains his calmer and gentler personality, so long as he isn't attacked; unlike the neutral or evil incarnations of the character.
  • Cosmic Horror Story:
    • Bagan comes off more as an Eldritch Abomination than it does a kaiju.
    • The same applies to Grogar, who's on a similar tier to Bagan and having similar vague and shifting depictions of him. He also has a Tome of Eldritch Lore he gave to his students that gives off a similar presence to Bagan's.
  • Crossover: A Shimmer in the Dark is a crossover involving The Bridge's incarnation of Rodan and Mizu winding up in the The Shimmerverse.
  • Curb-Stomp Battle:
    • Pit one of the most tanky and seasoned veteran fighters amongst Terra's native kaiju against a half dozen slightly smaller, inexperienced, and less durable dragons; and you can guess what happened when Anguirus after reverting to his full form thanks to Rainbow Dash intervened against the greed grown versions of Garble's gang.
    • According to the timeline, Trespasser got a severe one from Junior when it ticked him off. Mutavore didn't even get the chance to get clear through the portal before getting fried by Junior.
    • In their first meeting 370 years ago, Grand King Ghidorah dished one out to Monster X. Then X turned into Kaizer Ghidorah and returned the favor.
  • Darker and Edgier / Lighter and Softer: An odd example as the story has its lighter and dark moments in fairly equal number, going for more of a balance between the two franchises. It's certainly darker at times than Friendship is Magic usually is, having scenes or sequences far more mature than the show has; but utilized a Lighter and Softer take on the kaiju series, such as using a heroic incarnation of Godzilla instead of a True Neutral or evil incarnation. Compared to most other MLP/Godzilla crossover stories like My Little Desotroyah, The Bridge includes a lot more humor and light heartedness.
  • Deadly Prank: A Changeling decides to transform into Slendermane and scare approaching ponies, only to be nearly killed by Destroyah.
  • Designated Girl Fight: Downplayed and subverted significantly as multiple battles were present before it with gender as an afterthought, but the first kaiju on kaiju rumble in Equestria is Mothra vs. Gyaos.
  • Divine Intervention:
    • A currently then unnamed spirit or deity, Harmony, is the one who converses with and sends King Caesar back into Equestria's past.
    • Happens again later on when the same being saves Twilight Sparkle's life and convinces Monster X to spare a guard.
    • Considering Mothra's mythical status, she coming to Twilight's aid could arguably count.
  • Double Meaning: Xenilla repeatedly calls Godzilla Junior "Icka'brod", meaning "Brother" and always refers to him as his little brother. This is both Xenilla using it to get under Junior's skin after the latter denies the familial relation and foreshadowing the fact Xenilla sees Junior as family and loves him as such.
  • The Dragon: It's shown so far that Destroyah plays this role to Xenilla, albeit begrudgingly at best. Subverted in that they start out evil and are certainly not kind, but they are not the villains of the story. And Destroyah's grouchy demeanor doesn't stop her from being the only Mutation actually loyal to Xenilla.
  • Dragon Ascendant: Sombra, Discord, Tirek, and Chrysalis all became Big Bad level threats in their own right after their mentor, Grogar the Shadow King and Nexus of Dark Magic, was sealed away by Harmony.
  • Dramatic Irony: There's quite a bit of this, as not all of the non-kaiju characters know that the newcomers they're interacting with are normally gigantic monsters.
    • Xenilla is an enormous reptilian mutant born in the depths of space, leader of an entire faction of Kaiju, and bent on the conquest of Terra. Seeing such a villain awkwardly comforting Sweetie Belle to keep up appearances is absolutely priceless.
    • When Sunset Shimmer meets humanized Hyper Gyaos in the Equestria Girls realm, she assumes that Gyaos is from an abusive family due to her Broken Bird demeanor and claiming not to have a name. Given that Hyper Gyaos's "family" consisted of a mindless flock of horrific flying monsters that regularly turned to cannibalism to sate their unending hunger, Sunset is more right than she could ever begin to fathom.
    • Both the Sirens and Monster X assume Enjin is after the Siren's magic after it tried to attack Aria in the hospital, forming an Enemy Mine team-up to deal with it. Unbeknownst to them, Enjin is actually after kaiser energy that's within Monster X and Aria after her exposure to Kaizer Ghidorah.
    • Sunset and the Sirens meet long before their Rainbow Rocks encounter, but while both notice something a little off about the other, neither seem to actually realize what the other is.
  • Dreaming of Things to Come:
    • Celestia has a vision of the gyaos attack on Canterlot (and Godzilla's counterattack) shortly before it happens.
    • Upon his 'birth', Xenilla got a onslaught of them foreseeing some monster that would destroy Terra. He assumed it was Godzilla.
    • Rarity has a nightmare of the Big Bad's forces destroying Equestria if he succeeds in his plans. It would appear to have been sent by the Nightmare Forces.
  • Dug Too Deep: The short "Extinction Hour" reveals Bagan was freed from Attu Island when an aspiring archaeologist named Andria Young inadvertently broke an artifact maintaining his seal while drilling. Though Tarbtano says that he would have broken out sooner or later and Andria's mistake only accelerated the process.
  • Dumbstruck:
    • Played for Laughs with Rarity upon Anguirus casually admitting to be over 70,000 years old. After a bit she takes it in stride and jokingly asks for his aging secret.
    • A more dramatic example was in chapter 33. Moonbeam Glimmer gets one that lasts for hours after Godzilla Junior confronts her by... putting some flowers on her parent's grave, saying he forgives her for what she put him through, and says she needs to forgive herself to get through her Survivor's Guilt. Seeing someone she'd pegged as a monster act so benevolently throws her entire mind out of the loop for the rest of the chapter.
  • Dynamic Entry: Godzilla Junior returns to his full power in a brilliant display, complete with a massive Pillar of Light.
  • Emerging from the Shadows: King Sombra naturally does this a lot.
  • Enthralling Siren: The Dazzlings naturally. Raiga also ends up as one for her new Equestrian form, though has no clue how the singing magic works. We also get mention of the Dazzling's Mirror Universe counterparts called The Muses, who were apparently a benign version of the trope.
  • Establishing Character Moment: For some of his gruffness and more villainous incarnations, the moment the princesses and Mothra ask him to help save Canterlot and he agrees on his own free will to fight off a 200+ strong flock of Gyaos; we know we definitely have a heroic Godzilla on our hands.
  • Even Evil Has Standards:
    • The Nightmare force/Pony of Shadows might be the literal spirit of Nightmare Moon and wanted to rule Equestria as a dictator, but even she is terrified of the Big Bad in an Evil Versus Oblivion way.
    • Practically Monster X's calling card, to the point he is so restrained from excessive violence and destruction he doesn't really act like a villain at all. Word of God has compared The Bridge's version of X to a soldier in an enemy army. They may be fighting for the other side, but doesn't dictate them being moral or immoral.
  • Everything Is Better With Princesses: Xenilla doesn't think so. Though he respects Celestia and Luna's power, he thinks it's ridiculous that they call themselves princesses and not Queens. Upon finding out the ruler of the Crystal Empire was another Princess, he was down right dumbstruck and couldn't proceed without asking Cadance what was up with the titles. Hilariously, nopony could give him an answer as they apparently never gave it thought.
  • Every Scar Has a Story: Princess Luna and Godzilla Junior exchange some explanations upon pointing out each others old wounds.
  • Everything's Better with Dinosaurs: A good chunk of the kaiju roster are or were derived from Mesozoic life. Godzilla Junior, Xenilla, and Raiga (Ceratosaurians), Anguirus (Ankylosaurid), and Rodan and Irys (Pterosaurs).
  • Evil Counterpart: Xenilla plays this straight to Godzilla Junior at least in the latter's eyes. Some interaction makes it seem like Xenilla is more of an Anti-villain than the straight up monster Godzilla thinks he is. Xenilla himself gets one in the form of King Sombra, another crystal creating villain who uses both brains and brawn to achieve goals; and are usurpers to a "throne". However Xenilla is reigned in by Pragmatic Villainy and is really Good All Along whereas King Sombra is a boastful, self described sociopath who delights in mayhem.
  • Evil-Detecting Dog:
    • Fluttershy's animals react with fear to Xenilla, but she doesn't notice.
    • All animals steer clear of Enjin.
  • Evil Is Bigger: Zigzagged. For instance many of the larger Equestrians and kaiju are larger than average, but there are also many large heroes. While Grand King Ghidorah is a full 50 meters taller than Godzilla Junior; Junior is much larger than the gyaos who only proved to be a threat via Zerg Rush. Princess Cadance is shorter than King Sombra, but Xenilla's unicorn form is slightly larger than the latter.
  • Evil Knockoff: In a sense: while Grand King Ghidorah was the more evil of the two, the Heisei King Ghidorah is explained as having been based off the future people's records of Grand King Ghidorah.
  • Evil Power Vacuum: With Xenilla and Destroyah in Equestria, their faction has turned on each other, fighting for control. Note, this more or less starts the second they disappear.
  • Evil vs. Evil: This happens a lot.
    • Red, demonic murderer who indulges in torture vs. the story's Big Bad, a cold and calculating destroyer. Red would have won if the fight continued longer, but was outnumbered and forced through a portal into an unknown dimension.
    • A lesser example would be the short duel between Monster X and Grand King Ghidorah. It's quite clear those two do NOT like each other even if they are technically on the same side now. It's shown this isn't the first time they've thrown down.
    • In the holiday specials, we have Gigan vs. Mane-iac and human form Monster X vs. Aria Blaze and Sonata Dusk.
    • King Sombra vs. Xenilla. Though again, the latter's place on the morality scale is debatable.
    • A team fight breaks out with Gigan, Megalon, and Irys vs. Grand King Ghidorah.
    • The trope gets taken to the extreme when Enjin is sent to the human realm from Equestria Girls. Lacking developed heroes to face it, Harmony has to rely on Monster X and the Sirens as the best chance to fight it off.
    • Part 2 of Chapter 29 makes it clear that even though Kaizer Ghidorah opposes Grand King Ghidorah, he is not a good guy because he doesn't care about anyone else and will gladly kill them just for being there.
    • Chrysalis secretly intends to use her Villain Team-Up with Bagan's forces to restore her Evil Mentor Grogar, fully expecting this trope to come into play between him and Bagan, with her money on Grogar.
  • Exactly What It Says on the Tin: The FiMfiction page extends the title and says precisely what kind of crossover it is.
    • Played for Laughs with the humor based Halloween chapter. "Gigan gets attacked with shampoo as Megalon cosplays a Pirate".
  • Expy: Because most of the kaiju only get hints of their personality in the source material, Tarbtano gave them all some traits to fill in the blanks. The result is minor cases of this underneath the source material, though thankfully in a tactful way that doesn't turn into Captain Ersatz.
    • One reader noticed Monster X has a similar personality to Zen-Aku, with a possible Shout-Out scene. Word of God confirmed this was intentional.
      • Several readers also noticed that his human form when in the Equestria Girls realm very closely resembles Homura from Sekirei. Tarbtano evidently had never even heard of the series, but did note it was a very odd coincidence.
    • Mothra seems to be a mix of her canon self from the Rebirth of Mothra series with some Lady Palutena and Leona thrown in.
    • Anguirus appears to be channeling WheelJack at times.
    • Rodan has more than one similarity to The Flash.
    • Xenilla's behavior has been compared by readers to Alucard, with the author playing with this and giving him some lines reminiscent of the infamous abridged series.
      • The revelation that Xenilla's failed patricide actions, which indirectly led to the death of Godzilla Senior, were based on a desire to save the world and avoid unnecessary deaths, coupled with his desire to act as an evil enemy to his 'brother'Junior to make him strong enough to kill him also makes Xenilla have similarities with Itachi Uchiha. Also, just like Itachi, Xenilla starts to show more empathy and emotion after his ruse was revealed.
  • Face Palm: Gigan does the closest equivalent he can do with no hands, upon seeing Megalon's antics.
  • Famous Ancestor: Blueblood is a descendant of Princess Platinum, accounting for his royal title. Flash Sentry belongs to a long line of esteemed royal guards and police officers, his great-great-great grandmother was a captain helped liberate Trot during the changeling invasion hundreds of years ago. For her heroism, "Captain" became the highest rank in the Royal Guard.
  • Fire and Brimstone Hell: Zenith was this upon its first appearance. Averted once the Big Bad puts it under new management, turning it into a smooth flat plane of obsidian and frigid air.
  • Fix Fic: To a minor degree. The Father's Day special fixes the apparent plot hole in the Hearth's Warming Eve special where two alicorns that look like Celestia and Luna appear on a historic flag that predates them. In the special, it's establish via flashback that alicorns are a fictional species up until that point and the then infant sisters resembling the flags is taken as a good omen.
  • Flat "What.": Anguirus gives one (albeit with an accent) after seeing Derpy Hooves come barreling into the palace, erratically flying around and nearly crashing into several characters before delivering her letter to Celestia and departing.
    Anguirus: ....W'at?
  • Fling a Light into the Future: Anguirus and Rodan were members of a series of artificial guardian beasts made by now extinct civilizations from the distant past, circa 70,000 BCE. They were specifically made to protect the world when Bagan was set to return 100,000 years later; but got woken up early. Unfortunately, so did Bagan.
  • Flipping the Bird: Gigan and Xenilla have both mentioned they would do this if they had fingers.
  • The Fog of Ages: Princess Luna's earliest memory is a sweet gentle voice who may or may not be her mother. The next is of her and Celestia as children being found and raised by a foster family.
  • Follow the Leader: Most crossovers between Kaiju properties and MLP were done mostly in the sense of taking a kaiju film and putting in ponies in place of humans, reusing film plots; and/or throwing the kaiju into Equestria fully formed but otherwise just as pure monsters. The Bridge was the one that either started or popularized the ideas of using a wholly original plot with transformed kaiju being given alot of characterization. Post-Bridge, several stories began using very similar ideas.
    • My Little Destroyah technically did the Kaiju-to-Pony transformation first and had a lot of dialogue coming out of its titular character, albeit it's scale was much smaller and it still mostly used Godzilla vs. Destoroyah's plot for it's latter run.
  • For Nightmare Night, I'm Going As Myself: Megalon gets mistaken for being in costume, and talked into going trick-or-treating with Pipsqueak.
  • Foreshadowing:
    • The Mirror Universe's Xenilla utterly loathes his world's Godzilla Junior and Mirror!Godzilla wants them to team up. When one takes into account this means the main world's brothers have a perspective flip, it hints that Main!Xenilla actually doesn't hate his brother.
    • King Sombra mentions being Grogar's pupil. It later turns out so was Chrysalis and Tirek, and he's not only the Greater Scope Villain for the Equestrian side, but the 'nexus' of dark magic itself and comparable to Bagan himself. Chrysalis decides to turn the offered Villain Team-Up with Bagan into a plan to resurrect or restore him.
  • Friend or Foe: The fight with Princess Luna and some guards against Godzilla was primarily caused by a misunderstanding. The former party just woke up in a daze and when a guard grabbed his hoof, he thought he was being attacked. This spurs a brawl against some of the guards which gets Luna involved.
  • Generation Xerox: Cadence apparently looks exactly like her ancestor Princess Amore. However, it's implied that Amore was actually Cadence's mother.
  • Genetic Memory:
    • Xenilla, being a mutated clone of Godzilla Senior, starts getting some memories from his "father" in his dreams.
    • Mothra has this too, having some of the memories of all her predecessors (mother, grandmother, etc) as well as her "father" Battra.
  • Gentle Giant: Godzilla Junior note  and Princess Celestia note . Both of them are their world's respective Big Good.
  • Getting Crap Past the Radar: In-Universe. The Power Ponies comic book world is Rated A for all ages; no blood, gore, extreme violence, or sexual themes allowed. Mane-iac suggestively implies to Gigan they can still do that last part as long as they do it where the reader can't see them.
  • Glowing Eyes of Doom: As in canon, happens a lot when certain characters are either charging up or expending large amounts of energy. Most often with the princesses and godzilla siblings.
  • God Save Us from the Queen!: Invoked against but thoroughly averted by Princess Celestia, but not everyone thought so at first. When she was forced to banish the Nightmare Moon turned Luna, some in the past saw it as her trying to make a tyrannical power grab and launched the "Nights Rebellion". Celestia managed to peacefully dismantle the uprising without bloodshed by proving she was everything but this trope. Still the fear of being seen as this is why Celestia turned down the title of Queen even as she grew up and had a solo rule, keeping her Princess title to seem more approachable.
  • Godzilla Threshold:
    • Funnily enough, unleashing Godzilla Junior on the oncoming Gyaos horde heading for Canterlot is not this. While Princess Luna was not a fan of the idea at all, Celestia, Twilight, Mothra, and Junior himself all agree to it and multiple parties work to keep the fighting outside the city limits.
    • Played straight with Harmony having to rely on a team up between Monster X and the Sirens to protect the Equestria Girls realm from Enjin, because none of the heroes in that world are strong enough.
  • Go Mad from the Isolation: Subverted with the unnamed narrator of Time and Isolation (Monster X). He stays sane despite being imprisoned for decades, but isolation and relentless nightmares cause his memory to degrade into nothing.
  • Good All Along: Xenilla's entire role as the Evil Counterpart to Godzilla Junior? All a lie so he could constantly push his brother to get stronger and stronger for his own and the world's safety.
  • Good Animals, Evil Animals: Discussed and inverted when it comes to how Godzilla Junior viewed the animals around him from his youth. To him, typically "bad" animals like snakes or lizards weren't too active but were placid, didn't kill more than they ate, and didn't bother him. By contrast he hated the "good" animal example of dolphins, finding them to possess a cruel intelligence, killed for fun; and frequently harassed him before he got big enough to scare them off. This is why he had no qualms about eating them and whales during his teenage year, despite humans and Equestrians reacting with shock at the idea he could be so nonchalant about it.
  • Gotta Catch Them All: The Big Bad regularly has his group explore the multiverse and gather as many magical artifacts as possible.
  • Greater Scope Villain: It's revealed that dark magic has a different 'nexus' from other types and Chrysalis, King Sombra, Tirek, and possibly Discord learned it from that nexus. Chrysalis near instantly turns the offer of a Villain Team-Up with Bagan into a plan to restore said nexus and Legion compares his magic to Bagan's. Said nexus? Grogar.
  • Grievous Harm with a Body: What weapon does Godzilla grab to bat away scores of Super Gyaos rushing him? One of the Super Gyaos rushing him.
  • Grim Up North: The Big Bad was sealed away under an uninhabited island in the North Sea called Attu.
  • Groin Attack: Monster X takes one with a metal pipe from Sonata Dusk, because in a human body he wasn't aware that was a weak spot and got caught off guard.
  • Guys Smash, Girls Shoot: Zig-zagged with the kaiju. Mothra might prefer to keep back and fire barrages of energy blasts because her form is less adept at close quarters brawling. On the other hand Destroyah has absolutely no qualms about ripping her foes apart at range or up close. Surprisingly averted with the MLP roster.
  • Halloween Episode: A bonus chapter focusing on the misadventures of Gigan and Megalon has the latter getting roped into trick-or-treating with Pipsqueak (who thinks he's just in costume) and enjoying himself.
  • Handshake Substitute: As Gigan and Megalon don't normally have hands, they and Monster X bump forearms instead.
  • Hate Plague: In the Holiday Special, the Sirens have been inducing these everywhere they go, causing people to argue and fight.
  • Hearing Voices: The being that brought King Caesar to the past chimes in with both Monster X and Twilight. The former to keep him from killing a guard, and the latter to save her from a Gyaos.
  • Headbutt of Love: For Xilians, this is the equivalent to a kiss. After about half a dozen chapters of Character Development Monster X gives one to Aria Blaze, which she afterwards escalates into a Big Damn Kiss.
  • Heel Realization: Moonbeam Glimmer realizes how wrong she'd been about Godzilla Junior when he comforts her at her parent's graves and left some flowers, as per Fancy Pant's advice, on the headstones; showing he was completely different than she'd believed.
  • Hidden Villain: Combined with Dramatic Irony. The ponies and heroic Kaiju believe that the malevolent kaiju at large in Equestria were simply brought there accidentally by the Dimension Tide. Unlike the reader, they have no idea that the apparent rogues are all part of a single malicious faction, and that there's a Big Bad organizing them.
  • Holding Out for a Hero: Celestia starts to worry that she coddled her little ponies too much during her reign, making them depend too much on her or heroes to protect them and solve their problems.
  • Hope Spot:
    • Mothra beats the Hyper Gyaos and the lesser ones it brought with it, only for an even larger flock of them to show up and attack Canterlot.
    • In chapter 29, X and Aria defeat and seemingly destroy Enjin, unfortunately Bagan simply revives Enjin while X and Aria were distracted, allowing Enjin to successfully capture and absorb Aria.
  • Horrifying Hero: Canterlot's opinion of Godzilla during the Gyaos attack is mixed. Some cheered for him when he won, others were too focused on his brutal fighting methods and frightening appearance.
    • This has led to half of the general populace to view Godzilla and the other kaiju as a threat.
  • Hospitality for Heroes: Berry Punch gives Captain Frost and Godzilla Junior a free lunch after recognizing them at the pub she works at.
  • Humanity Ensues: Just like ponies, kaiju turn into humans when they enter the Equestria Girls realm.
  • Humans Are Ugly: Monster X remarks that this about the inhabitants of the Equestria Girls realm. Ironically, thanks to his amnesia, he's forgotten that he used to be a Xilian.
  • Humans Through Alien Eyes: Upon visiting the Equestria Girls realm and seeing humans up close for the first time, Monster X can't help but comment on how bizarre they look.
  • The Hunter Becomes the Hunted: The Hyper Gyaos, after being wounded and weakened by Mothra, gets chased by the rest of her flock when they smell her blood. She's forced to kill them all in self-defense.
  • Hurting Hero: Several Equestrian and Kaiju heroes have their baggage. Godzilla Junior is hauling around Survivor Guilt that his continued life being a constant reminder his father died, knowledge that his powers make it unsafe to be around his mother; and internally yearns to stop fighting and just live in peace. But, because of a strong sense of responsibility to keep fighting for those who can't, he knows any peace he gets is just a brief respite.
  • Hybrid Monster:
    • While "monster" is a bit of a subjective term, the Sirens were born between a union between two mermare princesses and two unknown fathers; creating a distinct trio of beings instead of the typical mermare reproduction. note 
    • Subverted as they are both in human form, but still played straight in terms of powers. Aria Blaze continually using Kaizer Ghidorah as a power source gradually gives her more and more of his traits such as dark coloration and enhanced strength. This effectively makes her a siren/ghidorah hybrid.
  • Idiosyncratic Episode Naming: The chapter titles for ''Sound of Thunder" form a poem when combined.
  • I Kiss Your Hand:
    • Xenilla kisses Fluttershy's hoof while expressing gratitude for sheltering him while he was unconscious.
    • Rarity also tries to teach Anguirus to do this when instructing him on manners. Hilariously enough, he refuses, pointing out that she walks on those hooves.
  • "I Know You're in There Somewhere" Fight: Gigan does this when Monster X transforms into Kaizer Ghidorah by recounting his various memories with the team. It works momentarily, but Grand King Ghidorah attacking undoes all his efforts.
  • I Need a Freaking Drink: Pretty much everyone in attendence's reaction after the incident at Ponyville with the Destroyah swarm.
  • Imported Alien Phlebotinum: One of the big nails in the Amalgamverse: the Mysterians integrated into Earth's population and contributed their technology, granting a boost in nuclear technology and metallurgy that made things like Super X possible. After the Final Wars, humanity got to work on reverse engineering the various alien technologies left behind, granting them another huge boost which includes the ability to create Space Titanium (the stuff the Showa Mechagodzilla was made of) on their own.
  • Improvised Weapon: After nearly getting run over by Aria and Sonata's car, a human transformed Monster X picks up and uses a broken metal fence pipe as a bo staff to damage the car after jumping on.
  • Inconvenient Summons: When Twilight, Mothra and Luna cast a mass teleport spell in order to summon the remaining Mane Six and Kaiju Rarity has the ill-fortune of being summoned whilst in the middle of a bath, bathtub and all.
  • Insistent Terminology:
    • Xenilla insists on calling Cadence "Empress" no matter how many times she corrects him, since he can't wrap his head around the idea of a Princess ruling an empire. Poor Shining Armor, as a non-royal who married into the monarchy, can't get him to stop calling him "Consort".
    Xenilla: I'm eager to see this.. crystal empire of yours, Empress.
    Cadance: Princess!
    (later)
    Xenilla: Considering the architecture of your land Consort-
    Shining Armor: Prince.
    Xenilla: -Prince Consort.
    • King Ghidorah gets angry if anyone leaves out the "King" when addressing him.
  • Insurance Fraud: The Flim-Flam brothers attempt to collect by claiming their Super Speedy Cider Squeezy 7000 was destroyed during Godzilla's fight with the Gyaos swarm, when it really broke down before the fight. Before they can make it to Canterlot, baby Destroyahs overwhelm their wagon and destroy it.
  • Interspecies Romance:
    • Braeburn (Earth Pony) has a crush on Little Strongheart (Buffalo), though he hasn't told her yet.
    • Two pony mares, Blade Dancer (Pegasus) and Princess Luna (Alicorn) have demonstrated attraction to Godzilla Jr. (who is in a unicorn body), though he is oblivious.
    • Anguirus (Earth Pony) has a crush on Ki Seong (Kirin). A later chapter reveals she likes him too.
    • Later on, Blade Dancer's attraction migrates to Xenilla (also a unicorn like his brother), and he on some level returns the feelings.
    • Subverted with Monster X and Aria Blaze after a long time. While both are very different species, a Xilian-Ghidorah hybrid and a Siren, they were both in human form.
  • Irony:
    • For a while, Princess Luna and Godzilla Junior are very wary around each other after the two's battle, even after the misunderstanding was cleared. She doesn't trust him at all and he think she means to do him harm. Guess who were the first two characters the fans shipped together with lots of fan art...
    • Gigan being flabbergasted that his attempt to make Mane-iac fall to her death didn't work on account of Toon Physics, considering Kaiju are probably the biggest violators of Square/Cube Law in fiction.
    • After seeing Godzilla in his true form, Blade Dancer is understandably thrown for a loop, and asks for reassignment so that she can clear her head away from him. She ends up in the Crystal Empire... and assigned to guard Xenilla, who looks almost exactly like Godzilla.
    • The Big Bad Bagan was sealed away beneath Attu Island, a real life island in the Bering Sea. Attu is uninhabited, but well renown for its bird watching and peaceful setting.
  • It's All My Fault: Mirror World's Xenilla blames himself for all the kaiju and people Mirror World Godzilla Junior has killed over the years because he spared him as a child.
    Mirror Xenilla: “All the souls I’ve murdered, for letting the child that grew into you live.”
  • Kaiju: No really, read the premise and take a wild guess what's in the story...
  • Kaiju Bites Pretty Much Everything:
    • Being a Combat Pragmatist, Junior has no aversion to using his teeth when the cards are down; as both Luna and the gyaos found out.
    • Runs in the family, Xenilla chomps down on a leg King Sombra was boxing him with, biting down hard enough to break the limb.
  • Just Following Orders: Monster X's reason for being a Punch Clock Villain, his memory is so destroyed the only thing he can remember of his former life as an Xilian guardsmen and soldier was following a master's orders.
  • Kick the Son of a Bitch:
    • Anguirus' Curb-Stomp Battle against Garble's gang after Rainbow Dash helps soften them up and he reverts to his true form with her help. This is after Garble and company terrorized a summer campground and tried to eat several fillies and colts.
    • The story goes out of its way to portray Grand King Ghidorah as a monstrosity. Seeing a Smug Snake like him getting absolutely trashed by a royally pissed off Kaizer Ghidorah was cathartic.
  • King Incognito: Subverted with Godzilla Junior and the get-up he puts on when leaving Canterlot Castle. It does fully cover him and hide his features like his distinctly crooked horn, coloration, red sclera, and nasal ridge. However by now everyone in Equestria not only knows what he looks like but also about how he's tall as Princess Luna and built like a tank, so when they see a covered upon pony about twice their size walking by it seems a majority knows who it is. However they're smart enough to know that if "King" Godzilla was going to such lengths to cover himself, then it meant he didn't want to be bothered.
  • Kissing Discretion Shot: It is heavily implied Aria Blaze pulled X into a kiss, but the scene change and the unclear wording mask it a bit.
  • Landing in Someone's Bathtub: Inverted. The mass teleportation spell to bring both the converted kaiju and Elements of Harmony to the throne room teleports in Rarity while she's still bathing, bathtub and all.
    Rodan: Oh look a white one.
    Rarity: *covering herself with shower curtain* WHAT IN THE NAME OF CELESTIA?!
  • Laser-Guided Amnesia: Monster X can't seem to remember a single thing about him prior to getting to the state he is in now, outside of some nightmarish still images.
    Marigold: *as she's giving a tarp covered X a cloak for the rain* What's your name?
    Monster X: I cannot remember...
  • Laser-Guided Karma: Grand King Ghidorah apparently killing the xilian leader, Controller 011, is what caused her transformed husband, Monster X, to unlock his full power and turn into Kaizer Ghidorah.
  • Last of His Kind: The Albino Hyper Gyaos, due to a combination of battles with Mothra (at the battle of the old castle), Godzilla (at Canterlot), and herself (in self-defense when they smell her blood and attack), had the rest of the gyaos killed off; and thus is the only remaining member of her species.
  • Layman's Terms: Twilight Sparkle gives a Magi Babble-heavy presentation on why the Kaiju turned into native species when they entered Equestria and how they can change back. Destroyah manages to summarize it in one sentence.
    Destroyah: "So in a nutshell, we got thrown into ponyland, magic barrier made us ponylanders, we can go back to our real bodies but only temporarily and we need a pony to change us."
  • Legacy Character: Two of the most notable Good Kaiju are this. Mothra Lea has a lineage including her mother, the Heisei Mothra, and dozens of other Mothra in the past. Godzilla Junior has both his adoptive father, Senior (the Heisei incarnation), and the 1954 beast all being his predecessors by the same name.
  • Legion of Doom: The Big Bad has assembled a multiple-franchise-spanning army of evil kaiju. And if his resurrection of Sombra is anything to go by, MLP villains will be joining the roster as well.
  • Let's You and Him Fight:
    • Early in the story, Princess Luna and the Royal Guard get into a fight against Godzilla Junior. It was all a big misunderstanding due to events outside their control. note 
    • Basically Harmony's plan to deal with Enjin. Lacking strong enough heroes to take on Enjin, she has to manipulate Monster X and the Sirens into fighting him. Helps that Enjin was targeting them to begin with.
    • Megalon and Sonata Dusk figure out this is happening and diffuse the situation when their groups run into each other.
  • Lightning/Fire Juxtaposition: The fight between Raiga and Agon in the opening to "Sound of Thunder", due to the former's presence summoning a thunder storm and the latter spewing napalm everywhere. "Lightning" wins.
  • Like Mother, Like Son: In a special, we get some pretty heavy implications that Godzilla Junior's selfless, responsibility driven attitude actually comes from his adoptive human mother, Azusa Gojo.
    • Subverted in regards to Junior and his adoptive father and predecessor, Godzilla Senior. As brought up by Azusa herself, Junior inherited his father's unbreakable will and determination, but is still his own being and not destined to be a repeat of Senior because of his own uniqueness.
  • Love Makes You Crazy / Love Makes You Evil: Kaizer Ghidorah's insanity, out of control powers, and unending desire to kill Grand King Ghidorah was spurred by the latter forcing him to watch his wife die right in front of him. note 
  • Made of Iron: While they can be physically harmed, the ponified kaiju and immortal alicorns are ridiculously durable for a pony.
  • Magic Feather: When Blade Dancer is evacuating citizens during the Gyaos attack on Canterlot, she encounters a young colt who is too scared to move. She has to let him wear her helmet to make him brave enough.
  • The Magic Goes Away: What happened to Terra (Kaiju home world) for the most part. 77,000 years ago they had The Fair Folk, Atlantis, and Magitek. Thanks to the Big Bad, the number of modern Terran magic users can now be counted with a single hand.
  • Magic A Is Magic A:
    • Equestrian magic is primarily driven by emotions and experiences such as love, friendship, hope, and will for good magic; and by hatred, greed, and wrath for dark magic. Terran magic by contrast runs off mana, a life energy all beings and planets have. The two cannot be used to counter each other. The one exception is Bagan and Harmony, who's magic so so pure and vast they can counter each other. However, according to Word of God, it's entirely possible for an Equestrian to learn Terran Magic, and in fact they'd be rather adapt at it due to their natural mana reserves. It's eventually revealed that Light and Dark Magic, while both emotionally driven, are distinct from one another to the point Bagan realizes Harmony can't be the nexus for Dark magic and sends Legion to Chrysalis to learn of it, discovering the nexus to be Grogar.
    • In regards to Equestrian magic, some seals or magical implements created and operated by the magic of a certain somepony requires them or someone with magic akin to their own, such as family or a student, to affect them. Celestia's anti-changeling wards for instance can only be discretely turned off by her or one of her students like Sunset Shimmer.
  • Magic Versus Science:
    • One could consider the fight between Luna and Godzilla Junior to be this from a point of view. One uses and was created by magic and hails from a fantasy series. The latter is a mutation brought upon by radiation and is firing back with plasma beams.
    • The magic all around areas like Equestria confuse Gigan's sensors, as they cannot quantify it.
    • The Cloud Gremlins use dark magic to make their storm clouds too tough for a Pegasus to break. Rodan applies the scientific principle of Thermal Expansion to weaken the clouds enough to break.
  • Make Me Wanna Shout:
    • Celestia putting her hoof down borders on this trope. And you thought Luna's Royal Canterlot voice was loud! When Celestia raises her voice, half the glass in the palace broke.
    • Anguirus is in the same league when in his full form. His roar at point blank range is enough to rupture a dragon's eardrums and stun it.
  • Manly Tears: Seeing and seemingly futilely struggling to revive Aria Blaze's apparently dead body causes the typically stoic, controlled Monster X to start crying before he finally managed to restart her heart.
  • Massive Multiplayer Crossover: In addition to Toho's creations, numerous kaiju owned by other companies make appearances, ranging from Legendary Picture's Pacific Rim Kaiju, to Daiei's Gyaos and Legion; to Yonggu-Art's Yonggary. In addition, some of the fan made Equestrian characters from the story's readers and other groups on Fimfiction make cameos.
  • Mêlée à Trois: The battle that starts the fic starts with simply Godzilla and Xenilla's factions duking it out...then the aliens, human mechas, and other kaiju all pile in. By the end over 50 kaiju were duking it out.
  • Mirror Universe: Tarbtano released a blog about a mirror version of Terra where the good kaiju are evil and vice versa, but noted it will probably not influence the rest of the story until the sequel. Though it does play a major part in the spin-off, Sound of Thunder.
  • Moment Killer: When Enjin is seemingly defeated, Monster X and Aria Blaze's tender moment is ruined when Bagan revives him and he grabs Aria.
  • Monstrous Cannibalism: The Gyaos here are far more mindless and primal compared to most Kaiju, and reflecting their animal like nature, will often turn to preying on weakened or injured members of their own flock to sate their insatiable hunger. The Albino Hyper Gyaos’s narration mentions that she had to fight off members of her own flock countless times whenever they try to attack her, it finally comes to head after being heavily injured by Mothra in a fight and she’s forced to slaughter the remainder of her flock in self-defence.
  • Mood Whiplash: Happens to Aria Blaze and Monster X twice for different reasons.
    • Monster X defeats Aria Blaze and has her completely at his mercy, leaving her no choice but to tearfully give up her siren heart necklace. Before she does, Sonata Dusk manages to catch X completely off guard by nailing him in his (very human) joy department, allowing the sirens to escape.
    • See Moment Killer for what happened after the two teamed up and learned to like each other. The tone instantly shifts from tender and calm to frantic and dire.
  • Mook Horror Show: Anguirus treats Garble and his gang to one once he returns to his true form.
  • Morality Pet: The Cutie Mark Crusaders are becoming this to Destroyah. While the latter party barely pays them any attention, the fact whom we are talking about has since never tried to harm them speaks volumes. They even managed to, much to all the kaiju's surprise, calm down the giant mare right when she was about to throw it down with Celestia.
  • Morton's Fork: Gigan, Irys, and Megalon get into one once they learn the truth of Monster X's forgotten history and what spurs the transformation into the extremely dangerous and out of control Kaizer Ghidorah. If they tell Monster X about what happened either he'll break under the knowledge of what his evil half did and transform into Kaizer. If they don't tell him and he finds out, he'll feel betrayed and turn into Kaizer. And considering his wish to Bagan was to have his memory restored, he's is going to remember eventually...
  • Mugging the Monster: Aria Blaze detects a being emitting a great deal of hatred and rage and seeks it out to feed. Only it turns out to be Kaizer Ghidorah, who is so powerful that even with the power boost she gets from feeding on his emotions, all she can do is run.
  • The Multiverse: Many of the MLP Expanded Universe, such as the Power Ponies and Equestria Girls realms are present, and even targeted by the Big Bad in addition to the main realm, Equestria.
  • Mundane Utility: How does Captain Blueberry Frost first put Godzilla Junior's strength to use? Betting on him in a Tug'o'war contest.
  • Music Soothes the Savage Beast: When under attack while trying and failing to mind control him, Aria Blaze unconsciously alters her tune and briefly calms down Kaizer Ghidorah with a new melody.
  • My Kung-Fu Is Stronger Than Yours:
    • Aria Blaze studied martial arts, which allows her to briefly contend with Monster X. However, he notes that a mere student cannot hope to beat an elite soldier with training and battlefield experience. She later takes up lessons from him during the siren's Enemy Mine alliance with X and shows great improvement.
    • King Sombra boasts that he was taught magic by the dark sorcerer Grogar himself, so no magic training Princess Cadance has could possibly compare. Cadance proves him wrong by getting the advantage and boasting she was taught magic by Princess Celestia.
  • My Master, Right or Wrong: Slight Deconstruction. When Monster X confesses following orders is just about the only thing he can ever remember doing, Aria Blaze quickly notes how little he knows about his new master, the Big Bad, and this could lead to trouble.
  • My Significance Sense Is Tingling: Twilight, Cadence, Luna, and Celestia all get headaches from the Kaiju's arrival.
  • Mythology Gag:
    • As a joke on their companies' rivalry, the Toho kaiju use the word 'Daiei' in place of the word 'hell'; and the Daiei kaiju use 'Toho' for the same word.
    Godzilla: Lady, what the Daiei are you doing?
    • Bagan’s history in this fic as a former guardian of Earth alongside a previous incarnation of Mothra and Battra is likely a nod to the cancelled Mothra vs Bagan movie where Bagan was an ancient protector of the Earth who tried to wipe out humanity. In fact all of Bagan's traits are effectively an amalgamation of all the scrapped movie versions mixed with the game version's power.
    • Princess Celestia was apparently offered the title of "Queen" during her 1,000 year solo rule, granted she turned it down as to not appear too high above the populace and seem unapproachable. During production of Friendship is Magic, she was going to be a queen but Executive Meddling lead to the change to avoid the God Save Us from the Queen! trope association.
    • Blueblood is given the full title of "Archduke Prince Heir Apparent". Similar to Celestia, Prince Blueblood was going to be "Duke Blueblood", but was changed. The story makes sense of both of the titles by calling him an archduke, which is the equivalent title to a non-ruling prince.
    • This isn't the first time we've seen a Gyaos get blinded by camera flashes.
    • Gigan and Monster X's handshake stand-in of crossing their forearms and bumping them is identical to a gesture between Gigan and Megalon in "Godzilla vs. Megalon".
    • Despite not appearing in any movies, Enjin is not an original character. The original version of Bagan proposed for the 1984 Godzilla reboot had it being composed of three shapeshifting monsters fused together, Enjin being one of them.
    • Mothra Lea playfully biting Godzilla Junior's tail is a nod to the fact nearly every continuities' incarnation of Mothra has bitten their continuity's Godzilla's tail for one reason or another.

    Tropes N - Z 
  • Neck Snap: Human Kaizer Ghidorah does this to Enjin. Due to Enjin's Healing Factor it doesn't kill him, but does slow him down long enough to be thrown into a freezing river and end up at the bottom of a lake.
  • Nice Job Fixing It, Villain: Destroyah pulls this, albeit completely unintentionally, when she attacks the Timberwolf pack about to kill the Cutie Mark Crusaders.
  • Ninja Pirate Zombie Robot: When Megalon goes Trick-or-Treating with Pipsqueak, he wears a pirate outfit despite being a alien cyborg beetle.
  • No Bisexuals: Averted. While not put at the forefront, several bisexual or possibly homosexual characters are mentioned in passing with no negative connotations. One of them, Blade Dancer, is arguably the main secondary heroine of the story.
  • No-Holds-Barred Beatdown: Aria Blaze flies into a rage after seeing Monster X bleeding, transforming into a Kaizer Ghidorah-like form and utterly trashing Enjin alongside a recovered X.
  • No Social Skills:
    • Anguirus knows a lot about civilization, but not manners or etiquette. Because he obviously doesn't enjoy being around Ki Seong, he goes to Rarity to learn some to try and fit into society while stuck there to avoid trouble.
    • Godzilla Junior similarly has a bit of a problem. While he is aware of a lot of modern life from observation and presumably second hand information from Lea, he has no clue what flirting or courting is. As such things of the sort either fly over his head completely or he grossly misunderstands them; such as thinking ponies and humans gave each other flowers as a edible treat since they are herbivores/omnivores.
  • Noble Demon:
    • Xenilla, when compared to his second in command. He has his goals, but won't act out for the sake of destruction unless he sees the need too. He at least had the decency not to blow up Fluttershy's cottage upon crash landing inside it. Being on the receiving end of 'the stare' helps.
    • Monster X plays this trope in spades, killing several of Legion's soldiers for attacking a pony who couldn't hope to fight back, and even bandaging said pony up before ditching him.
  • No Sell: Dragons would have more luck shooting Anguirus with a water hose than they would using their fire. Displayed spectacularly by Anguirus casually walking through a massive cone of fire completely unfazed. He IS a 'fire monster' after all.
  • Noodle Incident: On both franchises no less. The alien kaiju reference but refuse to talk about some sort of "Radio incident with the Kilaaks", and the Equestrians bring up some destructive event only referred to the "Chocolate Milk accident". What exactly happened isn't mentioned.
  • Not Distracted by the Sexy: Godzilla doesn't ignore Blade Dancer's flirtatious actions. He just has no idea what the context is and just gets confused as to what in the world she's doing.
  • Not So Different:
    • Aria Blaze and Monster X come to something of an understanding during the former's training with the latter upon finding out both are victims of circumstance and are wanting back something they've lost. Both have a concept of "home" they're missing and barred from getting back, Aria can't return to the sea, her literal home, because of her human form and Monster X can't return back to his metaphorical home due to his lost memories.
    • The non-canon April Fools day special defends My Little Pony G3 when Megalon, Sonata, and Pinkie Pie meet the G3 Pinkie. Both 'Pinkie Pies' hit it right off and Megalon points out that for all of its differences, G3 still had redeemable factors G4 carried on with.
  • Not the Intended Use: The Siren Heart necklaces can't be removed by any outside force except their wearer, as Monster X found out when he tried to take Aria's and got a invisible blow back force. He later uses this to revive Aria after Enjin choked her into unconsciousness, making a lunge at her necklace and using the blow back to jostle her awake.
  • Offscreen Moment of Awesome:
    • This story's version of Final Wars. Godzilla, Mothra, Anguirus, Rodan, Gamera, Yonggary, King Caesar, Raiga, Baragon, Gorosaurus, Manda, Gomora, and Varan AND Xenilla vs. Grand King Ghidorah, Gigan, Monster X, Orga, Hedorah, Megalon, Gyaos, Mechagodzilla; and the alien invasion fleets.
    • Ki Seong's restaurant gets invaded by several Destroyah babies. The next time we see her, she's somehow tamed them.
  • Oh My Gods!: Both casts frequently use their franchise creator's names.
    Godzilla Junior: "Good Tanaka!"
  • One-Gender Race:
    • Both the Mothra and Gyaos species are made up of parthenogenic females.
    • This results in the male Mothra Leonote  being genderflipped into Mothra Lea, who is otherwise identical as a character (Word of God confirms all of this). Tarbtano stated that since the species reproduces asexually, it would make more sense biologically for each offspring to be a clone-daughter to the mother. On top of that, Mothra is nearly always portrayed as and thought of as a female kaiju anyway.
    • Mermares are all female, and reproduce by mating with other species. If the child is male, it will be the father's species with some Mermare traits. If the child is female, it will be a Mermare with some of the father's traits. The Sirens were born from an unknown union of two mermare princesses and two unidentified males that was never replicated.
  • One Steve Limit: Subverted overall. Multiple characters with the same name show up, but usually with another moniker to distinguish them.
    • There are three Godzillas in the story verse at the same time: all of the Heisei timeline's Japanese Godzillas and both American Godzillas. However, only the original Japanese one is named Godzilla, while the other two from the American 1998 and 2014 movies are named Zilla and Gojira respectively. Justified, however, as they're ultimately three different species that just happen to look similar. There have also been three Japanese Godzilla's in the backstory, just not all at the same time; the original from 1954, his son "Senior" was active from the 1980s and 1990s, and then Senior's adoptive son "Junior", who is the current incarnation.
    • Subverted as well. The story also has two King Ghidorahs in its backstory, the planet killing Omnicidal Maniac and the future people's bio-weapon who was based off the original. Both are referred to as King Ghidorah, with the space monster being called Grand King Ghidorah to tell them apart.
    • Mechagodzilla is another subversion. While the Millennium Mechagodzilla is referred to as Kiryu, the other two exist and are both called Mechagodilla.
    • Like the Godzillas, there have been multiple Mothras over the eons with each successor being the last one's daughter. It is somewhat subverted when it appears that, as with the case of the current one Mothra Lea, each one had a distinguishing name with "Mothra" almost being more of a title.
    • The Heisei Rodan and the Rodan who appears in the story are separate characters, but both called Rodan due to looking similar.
    • There is also more than one Rainbow Dash. The Rainbow Dash we all known from the show is Rainbow Dash Junior, an updated version of the Generation 3 Rainbow Dash being her mother.
  • Origin Story:
    • Chapter 19 shows us the origin of Xenilla and Princess Cadance.
    • Chapter 24 shows us the origin of Monster X.
    • The Mother's Day and Father's Day specials double as ones for Godzilla Junior and Princesses Luna and Celestia respectively.
  • Our Mermaids Are Different: Equestrian mermares are a distinct, all female species inhabiting the Celestial and Lunar seas on either side of Equestria. The Lunar sea ones are primarily nomadic and live in small pods, whereas the Celestial pods have congregated together under a queendom with Mako Island as their capital. Bits of various real life Mermaid lore was used, so their behaviors can vary wildly. The Sirens are distinct trio of individuals which are the result of a crossbreeding of two mermares with a still unknown male of another species, a crossing which has never been replicated.
  • Pale Females, Dark Males: Zig-zagged with the over all designs of the transformed kaiju. While some of the female kaiju do have a dark colored coat (Destroyah), all of the male kaiju are predominantly darker colored (Godzilla, Anguirus, etc.); whereas the female roster have brighter and lighter colors (Mothra).
    • Justified Trope with Irys, she's albino. If she was a normal gyaos she'd be reddish-brown.
  • Partial Transformation: The Kaiju turned Equestrian characters retain some physical traits and their now diminished powers. This is shown best by Destroyah (now massive pegasus mare) still having her horn, causing many characters and readers alike to mistake her for an alicorn.
    • Played up with horrifying implications when more kaiju are sent to Equestria with fewer and fewer changes.
  • Pillar of Light: Happens whenever one of the transformed kaiju get hit with enough magic to return to their original form. Often bright enough to light up the night and be seen miles away.
  • Planet Terra: The world of kaiju and humans is referred to as Terra.
  • Play-Along Prisoner: Like brother like brother apparently.
    • When Junior is getting escorted out of the dungeons by a large number of guards while wearing large manacles and a thick muzzle, it’s made abundantly clear that he could break out and escape anytime he wants but simply goes along with it, at least until a particularly obnoxious guard begins antagonising him repeatedly prompting Junior to snap his restraints, burn through the muzzle and knock said guard into a wall before promptly holding out his hooves to be chained again. He later explains that he didn’t break out earlier because of the chance innocents might get caught in the crossfire and also because he was starting to suspect the whole brawl earlier happened due to a misunderstanding. Later, after seeing all his allies in the throne room, he promptly breaks out of them again by accident to run up to them.
    • Xenilla allows himself to get arrested by the Crystal Empire so that he'll be in the perfect position to ambush King Sombra. However, while he was strong enough to easily break free, he didn't anticipate that the prison would have an alarm system, so he needed Blade Dancer's help to escape without alerting Sombra.
  • The Power of Friendship: While friends is a big stretch, it takes Princess Cadance and Xenilla teaming up and launching a combined assault to defeat King Sombra.
  • The Power of Hate/The Power of Love: The power source for more advanced magic spells is partially emotion based. Good magic uses will, love, happiness, and hope. Dark magic, on the other hand, is fueled by greed, hatred, and wrath.
    • Siren magic uses the former in their songs, acting like a Hate Plague. Though Aria Blaze has discovered a new type of enchantment song that seems to use the latter, having a calming effect on the listener.
  • Power Trio: The core group of benign kaiju was this back on Terra:
  • Pregnant Badass: It's implied Princess Cadance is pregnant in recent chapters, and she still takes on King Sombra to defend the Empire.
  • Princesses Rule: Equestria's extensive use of this is lampshaded when Xenilla points out that, as ruler of the Crystal Empire, Cadence should be referred to as "Empress". When he questions why this isn't the case, none of the ponies he asks can answer — apparently, the thought never occurred to them.
    • It's more or less implied later that this was a side effect of Celestia's rule. She was offered Queenship, but turned it down as to appear more approachable by the then scared populace. Her rule was so good that 1,000 years later "Princess" has become the defacto highest title for a female ruler in emulation of her, making this a Justified Trope.
  • Psycho Rangers: The Anti-Villain counterparts to the above Power Trio.
  • Race Against the Clock: Rodan can only exist in The Shimmerverse for 24 hours, meaning he has only a day to help that world's Princess Sunset Shimmer stop a plot to destroy Canterlot.
  • Radiation-Immune Mutants: Subverted with all natural Equestrians. Because Equestria has so much free roaming magic in it, all the natural species like ponies and other species are so used to all that energy flying around that radiation doesn't affect them positively or negatively. Played Straight with Godzilla Jr. and Xenilla, who are mutated dinosaurs with an acquired radioactive power source.
  • Rasputinian Death: Enjin gets one, after several chapters of absolutely refusing to be critically damaged. note  However, even that failed to truly kill him as a fragment of his core possesses Sunset Shimmer.
  • Reasonable Authority Figure: Princess Celestia naturally. Mayor Mare also gets marks for not letting the hysteria some were spreading about Godzilla Junior get to her and take time to understand his intentions were good. Whereas some were calling for Junior to be brought to court, she wrote a request to the Princesses to grant him a full pardon of all charges and to be granted citizenship.
  • Reconstruction: The story as a whole could be taken as a reconstruction of tone for the Showa Era Godzilla franchise, which had far more gags and humor than the latter two most stories base themselves on. Numerous Lighter and Softer and Played for Laughs elements absent in other Godzilla fan works, even other My Little Pony crossovers, are given as much spot light as the more serious moments. Numerous readers have commented that the story's balance of humor and seriousness is a large factor in keeping it from going off the deep end like some others have.
  • Red Eyes, Take Warning:
    • The only feature an injured pony can see as a hooded figure (Monster X) looms over them is it's glowing red eyes. Subverted as the figure just saved them from several Symbiotic Legion and even bandaged them up due to an honor code, so the being meant them no harm.
    • Played straight with Aria Blaze after she absorbs a portion of Kaizer Ghidorah's powers. When his influence and power flare up in her a key indicator is her irises turning from violet to red. While she burns out a vast majority of the kaiser powers by the end to supercharge Monster X, she does still have a few speckles of red in her eyes when she wills it.
    • Inverted with Godzilla Junior. While his eyes do light up when using a charged beam or nuclear pulse attack, the glow is white. When his eyes do turn red it's because he's scared.
  • Related in the Adaptation:
    • In the Halloween special, Pipsqueak mentions Octavia is his cousin, while no known relationship between them exists in the show.
    • Raiga was a generic kaiju back in her own movie. Here, she is a member of Godzilla's species and considered an honorary cousin.
  • Rogues-Gallery Transplant: By merit of now being in a shared universe, the Gyaos from Daiei act as this for multiple heroic kaiju; functioning as the Starter Villain kaiju for Toho kaiju Mothra Lea and Godzilla Junior. note 
  • The Remnant: The Bridge: A Shimmer in the Dark features as its main antagonist Countess Mircalla, the last remaining one of Nightmare Moon's Generals, leading a reserve force that is all that's left of the latter's shattered army. Notably, she's lost faith in the cause, but keeps going out of debt to her former master (and because she knows that if she doesn't, the Always Chaotic Evil Nightmare forces will tear her apart for disloyalty).
  • Running Gag:
    • The characters of the two franchises use some of their principal creators' names whenever they say 'God'.
      • The ponies say "Faust" and "Bonnie", referencing Lauren Faust and Bonnie Zacherle, the principle concept creators for Friendship is Magic and My Little Pony respectively. Any character created Post Season 3 and for the Equestria Girls movies replaces "Faust" with "McCarthy", likely referring to writer Meghan McCarthy.
      • The kaiju roster says "Tanaka", referencing Tomoyuki Tanaka, one of the creators of the kaiju genre and the producer on almost all of Toho's monster films up until his death in the late 90s.
    • Every time Gigan enters one of the Equestrian human worlds, he either (much to his dread), encounters Mane-iac or gets hit with a hair care product.
    • Whenever a kaiju and sirens are all in the same world together, the sirens' van gets damaged or wrecked.
    • The CMC constantly botch pronouncing the pronunciation for Destroyah's name, many referencing all the alternate namings she's been given.
  • Samaritan Syndrome: Flash Sentry suffers from this, frequently finding himself assisting ponies he stumbles across. This is why he missed out on a lot of important events in the past. Unfortunately this gives him a lot of guilt thinking he could have done something to help stop a crisis instead of having been busy getting a hospitalized colt his lost toy.
  • Scars Are Forever: Played with. Godzilla does have a large number of permanent scars from past battles, but his powers repress them from sight most of the time. When he's especially drained of power however, they reemerge.
    • Luna has a permanent scar under her wing, from a long ago battle with Tirek.
    • Monster X has several scars on his face and torso, but they're obscured by his body armor.
  • Scar Survey: As mentioned above, both Luna and Junior are marked up and give each other a once over.
  • Sealed Evil in a Can:
    • Bagan, the most powerful being to ever walk Terra and the greatest calamity sentient life has ever encountered was sealed underneath Attu Island, an unassuming small landmass in the north Pacific.
    • The original Gabara was sealed in a chamber beneath Aokigahara, but was able to astral project.
    • Grogar, the Nexus of Dark Magic and a being on par with Bagan and Harmony, was imprisoned in his realm of Tambelon by Harmony, the entrance to which is beneath the Crystal Empire. Chrysalis and Sombra are planning to release him.
  • Seven Deadly Sins: Seems to be the overall motif of Grogar's students and Dark Magic. Tirek was greed, Sombra was wrath, Discord was gluttony (in the broader sense of hedonism), and Chrysalis is lust.
  • Shapeshifter Baggage:
    • Rarity asks where the Kaiju's mass comes and goes when they transform. Twilight theorizes that the magic that transformed them converted excess mass to energy. Otherwise, the Kaiju-Converts would be so heavy they would fall through the floor.
    • Changelings cannot alter their size when they shapeshift.
  • Shared Family Quirks: Subverted as they aren't related by blood by merit of the younger being adopted and the older being a "bastard child" of sorts, but both of Godzilla Senior's sons Xenilla and Godzilla Junior are actually pretty similar in some ways. Both of them have a habit of being very observant, have photographic memory; and question why the Crystal Empire royals aren't Emperors and Empresses.
  • Shipper on Deck:
    • Celestia, upon seeing how flustered but happy Luna was at getting roses from Junior, decides to get the latter shifted to the Night Guard. She lately playfully tells Junior Luna's Affectionate Nickname she knows note  she uses, knowing it'll fluster Luna.
    • Megalon was on board with Mane-iac's plan to marry Gigan, even offering to be the best man at the wedding. Granted, Megalon didn't understand that Gigan would rather have his head blown off (again) than marry Mane-iac.
    • Rarity and Pinkie Pie support Anguirus' and Ki Seong's mutual crush.
  • Ship Sinking:
    • When some fans started shipping Rodan and Thalia, the author was quick to torpedo the ship. Tarbtano pointed out Thalia, whom is owned by a friend of his, is already Happily Married to her husband Dallas, and she is meant to act as a Cool Big Sis to Rodan. Additionally, said interaction was based off the author's own Cool Big Sis in real life, meaning shipping them creeped him out.
    • As for Chapter 30, Blade Dancer's affections for Godzilla Junior have died off after her confusion period due to her accepting he didn't return the feelings, and her focus moving onto Xenilla. It's also well implied Xenilla is starting to return them.
    • Also in Chapter 30, Mothra Lea's reaction to being asked if she and Godzilla are married is to laugh and say that's ridiculous.
  • Shout-Out: Lots of them, both to official content from the source and outside franchises, fandom works, and unreleased series:
  • Shown Their Work:
    • The creators have shown a huge knowledge of both the kaiju movie franchises and My Little Pony. Fairly obscure references to how magic works for the latter is brought up several times, and the kaiju side of the crossover also include several little known kaiju like Raiga and unmade creations from Toho like Bagan, Enjin, Doragon, and Mizu.
    • The creators did an interesting take on what happens when you transform one species into another but keep some of the original form's traits. To merely exist in the gargantuan forms they did without imploding, most kaiju would need to be made of extremely strong muscles, bone, and tissue. This explains how Godzilla can walk through concentrated cannon fire with barely a flinch. Keep about 1% of this ability when shifted into pony form, it explains why despite not technically being trained athletes; most of the ponified kaiju are incredibly strong and very tough. note 
    • Tarbtano has paleontology and herpetology as his main interests and frequently shows his research in the works. For starters, dinosaurs and pterosaurs are referred to as two separate groups as opposed to having the latter lumped into the former.
    • The flashbacks to the ancient humans circa 70,000 B.C. all show them with features most similar to Eastern Africans and Austronesian aborigine regardless of their locations, such as upper-central Asia. This matches paleoanthropology models as the phenotype genes for many modern racial groups didn't emerge until tens of thousands of years later.
  • Shut Up, Hannibal!:
    • Monster X gives one the dark voice in his head (later shown to be Grand King Ghidorah) when it attempts to take over his mind.
    • When Xenilla gives Blade Dancer a speech deriding love as an addiction that controls everyone, she responds by punching him in the face (hard enough that he actually feels it), states that when she's felt love it's been real, not an addiction, and ends by stating that if he's ever felt love, then by his own logic he's as much a slave as anyone else.
    • During their fight, Xenilla interrupts Sombra's fight monologue by blasting him in the face, all while being rather bored and annoyed that Sombra won't stop talking.
    Sombra: You brute! Have you not evolved the ability to address your better?!
    Xenilla: No words needed. I'd have a human gesture for you, but I don't have any fingers at the moment.
  • Sibling Yin-Yang: Ironically with both franchises.
    • Princess Luna is much quicker to the trigger than Celestia, being very distrusting of Godzilla Junior until seeing his true colors. And while she was ready to throw her name into the ring if needed, Celestia's priority during the castle hall brawl was to stop it and figure out what was going on rather than join in.
    • Godzilla Junior is selfless, heroic; while quite smart, he has lackluster social and speaking skills. Xenilla is very articulate in his speech, easily comes off as an intellectual; but is Ambiguously Evil or Lawful Neutral at absolute best.
  • Sliding Scale of Idealism vs. Cynicism: Given the two franchises' tones, this really is to be expected to bounce around a lot. Over all it does lean on idealism.
    • On one hand the fully blown fights between the characters can be quite brutal, with visible injuries and often lethal end results. Most of the kaiju heroes do no abide by Thou Shall Not Kill. Situations can quickly turn dire and many of the heroes are carrying around more than their fair share of psychological baggage. Characters both good and evil can and do die, and many dark horrible things are trying to destroy Equestria.
    • But on the other hand, the heroes from both franchises are fighting against those dark and horrible things without losing their moral center. Having to resort to lethal force to stop a monster from killing dozens of innocent lives doesn't turn someone into a sociopathic Anti-Hero. And The Power of Friendship can often manifest itself in unorthodox ways.
  • The Smurfette Principle: While the ponies obviously don't need any help in this regard, extra effort is taken to avert this for the Kaiju. Mothra and Irys/Hyper Gyaos are established as being members of all-female species, and the usually ambiguous Destroyah is made explicitly female. That said, the trope still applies to the Kaiju Cast Herds individually, as they each have only one female member: The Terran Defenders have Mothra, The Mutations have Destroyah, and Monster X's group has Irys.
    • Justified Trope in the case of Destroyah, given there are only two Mutations in the story, so their numbers are gender balanced.
  • So Proud of You:
    • Azusa Gojo/Aoki was the one who helped raise the young dinosaur who grew up into Godzilla Junior, the two seeing each other as mother and son. She couldn't be prouder when her influence helped him grow into a hero that saved both her and San Francisco.
    • Godzilla Junior himself invokes this trope when he disagrees with Princess Luna's assertion that her father figure, Starswirl the Bearded, would see her as a failure for turning into Nightmare Moon; bringing up her helping to save Canterlot and growing into a beloved diarch since then.
  • Soldier vs. Warrior: Appears to be a core distinction between the more sympathetic antagonists, such as Monster X (soldiers) who are just following orders, and the more malign members of the roster who do so for their own prideful gains such as King Sombra (warriors).
  • Something Else Also Rises: Pegasi and Alicorns are shown to have a tendency to flare their wings out whenever they’re excited or flustered (mostly the latter):
    • Blade Dancer does this when Xenilla is questioning why she has Junior’s scent over her and she mentally curses the fact that her wings are doing this, describing it as a natural bodily reaction.
    • Luna gets this, alongside a Luminescent Blush, when she see’s that Junior brought her roses as thanks for everything she did for him.
  • Spanner in the Works:
    • Mothra Lea and Godzilla Junior prevented the Gyaos flock from claiming the Tree of Harmony and Canterlot. The Big Bad did not anticipate their interference at all.
    • If Xenilla hadn't been sent to the Crystal Empire, King Sombra would have likely succeeded in assassinating Princess Cadance.
    • Bagan doesn't want Monster X's friends to know he's in the Equestria Girls world, so when he brings Irys there so she can eat, he makes sure to drop her off in the city where Crystal Prep High School is instead of where Canterlot High School is so there's zero chance she'll run into X. However, several Canterlot High students were visiting the city for the red carpet premiere of a new Daring Do movie. Irys runs into Photo Finish, who had witnessed a fight between X, the Sirens, and Enjin, and took photos, thus alerting Irys to X's situation.
  • Spared By Adaptation:
    • Grand King Ghidorah, Baragon, Xenilla, Destroyah, and numerous other kaiju are all still alive due to changes in the timeline.
    • Due to the Terran Defenders and other mecha being present, many of the Jaeger teams who died in 'Pacific Rim are still around.
    • Stacker Pentecost survived the events of Pacific Rim thanks to Godzilla destroying the Rift the first time along with Mutavore, preventing his Heroic Sacrifice from being needed to close it.
  • Step into the Blinding Fight: Irys gets a slight advantage over King Ghidorah by extinguishing the torches around them. She isn't hindered as she can use echolocation. While he can glow and hear her echolocation, he can't pinpoint her.
  • Story-Breaker Team-Up: Despite there being a large difference in power between the strongest kaiju and the strongest Equestrians, measures were taken to avoid this. The Equestrians are still presented as very competent and having unique skill sets that complement the heroic kaiju's. And the situation the core group of kaiju are in require the Equestrians to get back to full strength.
  • Sufficiently Analyzed Magic: A rather odd example of an inversion. Twilight and Mothra submit some of Godzilla's hairs to various spell based tests, and find out his biological radiation is nearly identical to highly unstable magic.
  • Summon Bigger Fish: Let this be a hint. Garble and his gang are attacked by Anguirus after he transforms back into a Kaiju.
    • Flock of 0.25-12,000 ton Gyaos and Super Gyaos flying towards Canterlot? Throw up a shield and let the 60,000 ton Godzilla have at it.
  • Super Mode:
    • Aria Blaze after unleashing all the energy she's been siphoning off Kaizer Ghidorah gains a transformed state similar to Midnight Sparkle.
    • Raiga enters one after Mirror Starlight and Mirror Lightning Dust channel Manehatten's entire power supply into her, gaining Instant Runes all over her body and becoming powerful enough to overpower and come close to killing Mirror Godzilla. According to Word of God, this is her true form she would've awakened in had she not awakened prematurely, and all the Guardian Beasts have a similar form for the same reason.
  • Super-Powered Evil Side:
    • Nightmare Moon and Nightmare Rarity for Princess Luna and Rarity respectively. The form comes with a large power boost, at the cost of their wishes and fears (being forgotten and being replaceable) being bastardized.
    • Kaizer Ghidorah for Monster X, mixed with a Split Personality. Whereas Monster X is a rational Anti-Villain and very powerful in his own right, Kaizer Ghidorah is at least twice as strong but with a nonstop berserk rage.
  • Super Strength: Most of the kaiju both in their natural forms and Equestrian bodies. Godzilla Junior gets a unicorn body, but he is easily stronger than even multiple earth ponies. The only ones with comparable strength are the older alicorns like Princess Celestia, Luna, and Cadance; along with King Sombra.
    • Aria Blaze acquires a degree of this after her drawing power from Monster X/Kaizer Ghidorah makes her start copying their powers.
  • The Swarm: The Gyaos and Legion swarms.
  • Takes One to Kill One: Seems to be the case with Nexuses of Magic. Bagan, Harmony, and Grogar are so much stronger than everything else that the only thing that stands any chance of killing any of them in a one on one fight is one of the others. Bagan outright admits even Grand King Ghidorah or all three of his Aspects together wouldn't stand a chance against Harmony and goes after her personally (and even he only manages to tie). To note, both of them were only at 30-40 percent of their full power at the time. While Bagan was defeated and imprisoned in the ancient past, it took literally the entire Mothra and Battra species in order to do so and the Ancients expected nothing less than a small army of monsters stronger than Godzilla and created with Terra's entire remaining mana reserves to have a reasonable chance of defeating him when he eventually escaped. The only one who was ever able to beat Grogar was Harmony, and even then just barely.
  • Take That:
    • Tarbtano does not like the "Tyrantestia" and "Waifu Luna" memes at all, taking several jabs at them. note 
      • Celestia even specifically states they are "Not tyrants." when Luna initially proposes imprisoning the kaiju until a solution can be found, practically firing shots at the Tyrantestia meme by name. And just to drive the nails in deeper, it's stated several times that in the past Princess Celestia was offered the title of Queen note , but she turned it down for perfectly moral and selfless reasons.
      • Bold Rush is basically an O.C. Stand-in for a lot of 'Self Insert O.Cs x Luna' fic character's who are politically powerful and try to charm Princess Luna via feats. He tries to kill the ponified and chained up Godzilla with a sword. Several effortlessly snapped chains, a twisted sword, and smashed ribs later.... An unscathed Godzilla forced Bold Rush to be sent to the infirmary with his own (heavily annoyed) squad calling him an idiot.
    • A much lighter example would be a small jab at Hasbro for making every benign female ruler under Celestia's sun "Princess ___". Xenilla points out the oddity of Princess Cadance ruling the Crystal Empire, thoroughly confused why she isn't an empress.
    • Continuing the trend of off headcanons aimed at the alicorn sisters, recollections about Equestria's past from both Thalia and Princess Luna herself take of the "Nights Rebellion" that started to grow just after Celestia defeated Nightmare Moon. This rebellion was effectively a complete Deconstruction of the "New Lunar Republic" fan creation, throwing every allegation that group has ever wielded against Celestia and Nightmare and utterly demolishing it while telling it off as horrifically untrue propaganda. note 
    • After several Flash Sentry haters complained about his brief scenes (including a cameo where he didn't even say anything) and demanded he stop appearing in the fic, Tarbtano responded by giving him more scenes and promising to expand his role when the fic gets to the Rainbow Rocks timeline. Tarbtano also expressed displeasure that Flash became Demoted to Extra, stopped getting Character Development, and was made to look like a total chump in Rainbow Rocks and Friendship Games just because of several fans complaining to Hasbro about him. Tarbtano pointed out that like Flash, Sunset Shimmer used to be hated by the fans, but became an Ensemble Darkhorse because Hasbro chose to give her more screen time and Character Development in the later movies.
    • After several rude comments bragging that the Godzilla from Godzilla (2014) would make mincemeat of the fic's version of the grown up Godzilla Junior and demanding Tarbtano replace the fic's version with the 2014 one, Tarbtano wrote a semi-canon blog of the Mirror Universe's 2014 version losing to the Mirror Universe's Godzilla Junior. Though to soften the blow to the 2014 creature itself, as Tarb's gripe wasn't with it but its Fan Dumb, the 2014 Godzilla did put up a good fight and the bout ended in a logical way.
    • His words in the same blog imply Mirror Godzilla is one to the people complaining and demanding a Darker and Edgier Godzilla story. They got it: as the Big Bad of a Mirror Universe story.
    • Considering how disliked King Aspen and the other deer from "The Root of The Problem" were, it's hard to see Mirror Universe Godzilla destroying the Mirror Thicket Deer Kingdom and even eating some of the deer as anything else but this.
    • In part 2 of the April Fools special, one of the worlds Pinkie Pie, Sonata Dusk, and Megalon visit on their dimension hopping adventure is a blend of Titanic: The Legend Goes On and The Legend of the Titanic. The trio were disgusted and called it an atrocity, especially the rapping dog and the octopus. When they arrive in Pokémon, Sonata calls the adults in that world irresponsible for letting ten year olds wander a wilderness full of creatures that could easily kill people unsupervised.
  • That Came Out Wrong:
    • Nearly everything Godzilla Junior said to Starlight when talking about his interactions with various female characters. Junior is oblivious and talks about things that were entirely platonic, while Starlight keeps thinking it's innuendos and that Junior really gets around.
    • Synonyms are Monster X's worst enemy. Upon trying to take Aria Blaze's necklace (called the 'Heart of a Siren'), but learning only she can take it off; he demands she "Surrender your Heart to me.". Both parties were embarrassed.
  • The Faceless: Partially metaphorical, partially literal with Monster X. In his true form, his face is greatly obscured by a bone helmet fused to his head. In human form he's wearing a white mask and scarf. When Aria Blaze hits him hard enough to crack part of the mask off, she asks why he's hiding his face. X's retort?
    Monster X: "This IS my face..."
  • The Mirror Shows Your True Self: Much to his distress, Monster X sees Grand King Ghidorah appear in his reflection at a stream.
  • The Reveal:
    • The last paragraph of the bonus chapter is notable for this, as it reveals two previously unnamed characters. The first Monster X, appeared in an earlier chapter and was even the protagonist of the bonus chapter; going unnamed the entire time up until the last portion. The other was Gigan, whom X had crossed paths with and despite the two holding a conversation, he also was not revealed until the end.
    • It's eventually revealed that Chrysalis, Sombra, Tirek, and Discord all learned dark magic from Grogar, who is actually the nexus of it and on a similar tier to Bagan and Harmony.
  • Those Were Only Their Scouts: A group of Cloud Gremlins take control of a storm cloud and attempt to invade the weather factory of Cloudsdale. Since the storm cloud is protected by dark magic, it takes a bit of teamwork from Rainbow Dash and Rodan to stop it. Before they can celebrate, a much larger cloud carrying the main Cloud Gremlin force arrives, and the first wave even mentions they were just the scouts.
  • The Starscream:
    • Most of the Mutations would gladly kill Xenilla and take over the faction if they had the chance.
    • Grand King Ghidorah makes it clear he has no intention of being under Bagan's power for long and is just biding his time.
    • Queen Chrysalis joins Bagan's Villain Team-Up, but secretly plans to exploit it to restore her Evil Mentor Grogar to his full power, fully expecting Evil vs. Evil to kick in between the two evil Nexuses of Magic at that point and has her money on Grogar emerging victorious. King Sombra soon joins her after Bagan resurrects him.
  • Thou Shalt Not Kill: Discussed to some extent. Pretty well averted with both the Kaiju heroes and the Equestrian heroes when in dire situations. Godzilla Jr. and Mothra Lea have no qualms about mowing down hordes of gyaos if it meant protecting the civilians nearby; and neither Cadance or Xenilla pulls any punches against King Sombra. Unfortunately, a good chunk of the population is very much for this rule regarding their heroes and half of them are terrified that the Kaiju don't abide by it.
  • Tome of Eldritch Lore: Chrysalis possesses one, and implies Tirek, Sombra, and Discord possess the other three copies of it, all of which given to them by Grogar. It fits all the qualifications of it, including being evil and hideous in every sense. Legion describes Grogar's presence radiating from it as being comparable only to Bagan's. The four books also each possess a portion of the spell needed to open Tambelon.
  • Toon Physics: Besides Pinkie Pie's antics, the Power Ponies world runs on this. Being a realm literally inside a comic book rated A for all ages, anything involving gruesome injuries or deaths are physically impossible. Like Gigan dropping Mane-iac from hundreds of feet in the air and trying (and failing) to stab her, neither work.
  • Trapped in Another World: Dimension Tide sent the kaiju crashing into Equestria, and so far it's one way as there's no equivalent in Equestria to send them back.
  • Truce Zone: New Birth Island, where Biollante has made her home. She declares that the Defenders and Mutations' war will not happen there, and since she's powerful enough to restrain Junior and Xenilla, they have no choice but to obey her.
  • Trust Password: Monster X recites the time they dealt with the "radio incident with the Kilaaks" and what happened the day they first met to prove his identity to Gigan.
  • Tsundere: Mane-iac goes from fighting Gigan to attempting to crush on him after him hacking off most of her Prehensile Hair gives her a haircut she liked. All this happened in the span of five minutes. She turns into a full on Yandere.
  • Uncanny Valley: This is Blade Dancer's in-universe reaction to seeing Godzilla in his true form, since it's just similar enough to his unicorn form that she met him in to be unsettling.
  • Unhand Them, Villain!: When Destroyah grabs Mothra, Rodan says, "Hands off the bug!" She replies, "Okay." and throws her into him and Anguirus.
  • Unstoppable Rage:
    • Princess Luna takes all the kiddie gloves off and throws everything she's got at Godzilla Junior after the latter beat down multiple guards. Thankfully it was all a big misunderstanding.
    • To say Xenilla flies into one after being hit with Sombra's fear magic would be an understatement.
    • Kaizer Ghidorah might as well have this as is primary trait. Upon sensing or seeing Grand King Ghidorah, nothing is going to stop him from trying to rip the latter to pieces. It's mentioned during his Curb-Stomp Battle against King Ghidorah that Kaizer was tanking so much damage and exerting so much force in his blows that he was breaking his own bones from the effort, and even that doesn't stop him from severely mauling King Ghidorah.
  • Unusually Uninteresting Sight: Vinyl Scratch is rather nonchalant when her radio show receives calls from ponies being attacked by Baby Destroyahs. Even when several of the little monsters destroy an entire wall of her studio, she starts the next track with hardly more than a raised eyebrow.
  • Unwitting Instigator of Doom: Sonata Dusk attempted to use her powers on Monster X to force him to stop attacking. Come several chapters later, we find out the traumatic flashbacks he got due to her Mind-Control Music woke up the Kaizer Ghidorah personality; making him go on a rampage.
  • Uriah Gambit: Xenilla eventually confides to Blade Dancer that in the invasion of Solgell Island all the way back in the first chapter, he had actually been leading the Mutations to their deaths. Had Dimension Tide not interfered, the battle would have continued until all the Mutations were dead except for himself and Destroyah.
  • Villain Protagonist: The Halloween, Winter Holiday, and half the Valentines Specials followed Gigan, Megalon, Monster X, and Irys. Monster X would go on to lead his own story arc opposite Aria Blaze, detailing his forgotten history and current conflict against Enjin.
  • Villain World: The Big Bad and his underlings spend a majority of their time in a realm called Zenith. Originally a Fire and Brimstone Hell under RED, when Bagan took over it became a cold, dark realm with a single structure (a massive dark temple) and endless miles of featureless obsidian.
  • Villainous B.S.O.D.: The Hyper Gyaos after she's forced to kill the rest of her blood-crazed flock in self-defense, leaving her the only one left. And since she's sterile, she can't asexually reproduce like the others, leaving her literally the only one left.
  • Villains Out Shopping: Literally. Aria and Sonata were going about in a mall when Monster X ambushed them.
  • Villainous Rescue:
    • A flashback reveals that during the Final Wars, Xenilla saved Godzilla's life from a Kill Sat, and then destroyed part of the invading fleet, because he views Terra as his to rule.
    • Kaizer Ghidorah nearly murders Aria Blaze until he gets blindsided by Enjin, sent by Bagan to kill him and take his power.
    • Monster X saves the sirens from Enjin during the hospital attack, citing that their gems would be useless to him if they died.
      • The sirens later repay the favor by ramming Enjin with their van to save Monster X after the battle went in Enjin's favor and X was knocked out cold.
  • We Have Become Complacent:
    • Princess Celestia worries that because she worked for about 1000 years to keep Equestria free from war and crime, it is unprepared for the present threats, forcing them to rely on the displaced Kaiju to help them.
    • According to Grand King Ghidorah, a long period of peace was what left the Xilian homeworld vulnerable to his first attack on it.
  • Wham Episode:
    • Chapter 20: It's revealed that the mysterious entity directing the enemy Kaiju is Bagan, at the same time we find out that the Tree of Harmony is actually sentient and has been subtly helping Equestria and the heroic Kaiju.
    • Chapter 29: Bagan tracks down and invades Harmony's realm and while he fails to kill her, he damages her, the Tree of Harmony, and the Elements of Harmony sufficiently that she's left totally cut off from Equestria, unable to even operate from behind the scenes like before until they can self repair. At the same time Enjin successfully captures Aria, absorbing both her siren magic and a large portion of the Kaiser Energy that she's siphoned away from X to transform back into a kaiju. Monster X, the only one left in the EG realm strong enough to fight Enjin is knocked into and sinks to the bottom of a frozen lake.
    • Chapter 31: Not only does Xenilla have Godzilla Senior's memories, he also has the Mothra family line's memories, and he attacked Senior all those years ago due to misinterpreting them. Godzilla Junior finally learns Xenilla truly loved him and sacrificed everything to make him strong enough to survive. Finally, we learn Grogar taught several of the previous MLP villains like Sombra, Tirek, Chrysalis, and Discord magic, and he's a being on par with Bagan and Harmony. Chrysalis is offered a Villain Team-Up with Bagan's forces by Legion, which she accepts but secretly intends to exploit it as part of her own plan to restore Grogar to his full might.
    • Chapter 34: King Sombra is brought back to life again and begins conspiring with Chrysalis to release Grogar. Sunset Shimmer is possessed by Enjin and infiltrates Equestria.
  • White Sheep: Now that we see Godzilla Junior all grown up, it's very clear he's become this. Compared to his adoptive grandfather and adoptive father, he's the first outright heroic Godzilla.
  • Wonder Twin Powers: Celestia and Luna's magical prowess is much stronger when they are near each other. They are still powerhouses when alone, but being anywhere near one another increases their power by magnitudes.
  • Worf Effect: The Big Bad establishes himself as the more dangerous or crafty of the villains by defeating long time fandom Big Bads Grand King Ghidorah and Red.
  • Wrong Context Magic: As mentioned above (see Magic A Is Magic A), Terran and Equestrian magic work off different principles and can't be used to cancel out each other.
  • Xanatos Gambit: The entirety of the "Enjin Arc" was this as set up by Bagan, with the primary intent being luring in Harmony close enough to attack her realm directly. Enjin kills the sirens and Monster X/Kaizer Ghidorah and Bagan kills Harmony? Bagan just got a huge power source, removed a threat, and killed the only character who can stand on the same power level as him. Enjin succeeds but Bagan can't kill Harmony? Still get the power up and the damage to Harmony's realm from two Physical God tier characters fighting it in with severe her connection to Equestria so she can't intervene. Both schemes fail? The damage is still done to Harmony's realm so she is out of the picture for a while and without any ties to link Enjin to his master, Monster X will still loyally serve Bagan.
  • You Are in Command Now: After the main kaiju were transported to Equestria, control of Godzilla's faction fell to Gamera, who's acting as "Regent" in light of the "King's" absence.
  • You Didn't Ask: Xenilla has been aware Princess Cadance was pregnant with her and Shining Armor's child a full eleven chapters before everypony else note  He never said anything because he assumed they already knew and never had a reason to bring it up.
  • You Are Not Alone: Practically quoted by Princess Cadance during her Big Damn Heroes moment to save Xenilla.
    King Sombra: "It ends here, the beast dies alone..."
    Princess Cadance: "He's not alone!" *fires a blast wave into Sombra*
    • Later when Xenilla has gone into isolation due to trauma he experienced under Sombra's nightmare visions, Blade Dancer stubbornly refuses to be pushed away or scared off; knowing he's in pain.
  • You Can Talk?: This was Xenilla's reaction when he first met Destroyah. At the time, no one knew she was sapient.
  • You Can't Return To Your Realm: The situation with the first six kaiju that arrive. Dimension Tide brought them to Equestria and magic might be able to get them back, but for now they are stuck there. Mothra and Twilight are working on averting this.
  • You Have Outlived Your Usefulness: After Bagan gets an example of the power Monster X has in his Kaizer Ghidorah form, he decides to kill him and take that power for himself.
