Fanfic / Mischief (MHA)

"So…" The villain scratches his nose. "What exactly are you supposed to be?"
Izuku Midori-no. There's no one watching. No one here to see. He smirks.
"I am Izuku Lokison. Prince of Mischief." He spreads his arms out in front of him, a dagger appearing in each hand with a soft green glow. "And I am burdened with glorious purpose."

Mischief is a crossover fanfiction between My Hero Academia and Marvel Universe by KageNekem. It can be read on Archive of Our Own here.

The story follows Izuku Lokison, Prince of Mischief, as he seeks to fulfill his glorious purpose of becoming a hero.

Mischief provides examples of:

#-J

• 11th-Hour Superpower:
  • Izuku manages to unlock the cryokinesis from his father's side of the family during his fight against Shoto at the Sports Festival.
  • Ochako receives the power of the Ten Rings during her fight against Gorr.
  • Izuku unlocks his ability to fire energy blasts just as he and Bakugo are about to be crushed by an out-of-control ship during the Training Camp.
• Abled in the Adaptation: Thanks to his deal with Mephisto, Tensei is capable to walk again upon becoming the Ghost Rider.
• Aborted Declaration of Love: Thirteen (who is the embodiment of Izuku's love for Ochako) attempts to confess his feelings for her during the Sports Festival. The other clones find out and stop before he can do so.
• Above the Gods: During his brief appearance in Chapter 62, Doctor Doom mentions he tried to be a God once, but it was beneath him.
• Abusive Parents:
  • All for One's treatment towards Hirona is an emotional example of it. He always makes clear that she will never be as good as Tenko/Tomura would have and belittles her at any slight mistake.
  • Tenko's mother Nao is the only other person in his family other than Hana that he regrets killing. He still resents his grandparents for just standing there and letting his father abuse him, and as for the man himself, the boy doesn't even spare a thought about it.
  • Mustard's parents locked him in the basement of their house out of fear of his Quirk. Spinner's parents were the same, ashamed of his heteromorph looks, and Himiko's parents kicked her out of the house. In fact, most of the younger members of the League bond over this.
• Accidental Discovery: Maybe not so accidental, given that it was one of Nezu's goals, but during the Guardians Training Camp arc, Cosmo ends up reading Aoyama's mind and discovers he is the U.A. Traitor.
• Accidental Misnaming: Upon learning the story behind the Infinity Stones and the Multiverse, Denki confuses Thanos' name with "Thermos", "Thermometer", and "Thanatos".
• Actually Pretty Funny:
  • When Izuku attempts to use his class president "authority" to ask Momo to tell Katsuki that he and Izuku will be facing All Might in the finals, Momo promptly resigns from her vice-president position. Izuku and Kyoka burst into laughter after this.
  • While everyone is stressed out during the I-Island attack, Shoto quips that after USJ and Hosu, villain attacks have become quite mundane, which is why he is not at all nervous about the situation. That actually helps to lighten up the mood and the students thank Shoto for it.
  • Hirona can't help but snort and giggle when Nejire asks her if All for One doesn't sit in a dark lair all day hatching evil plots and laughing to himself like any Generic Doomsday Villain.
• Action Dad: Several examples throughout the story: Loki (a villain one) to Izuku, Thor to Denki, Vision to Billy and Thomas, Logan (a surrogate example) to Laura. Aizawa is not Eri's official parent yet, but both him and Eri are more than happy to let him take this role.
• Adaptational Dye-Job:
  • Denki's eyes are blue instead of golden. This also acts as foreshadowing about being related to Thor.
  • Tenya's hero costume changes from white to black with red stripes upon receiving the power of the Ebony Blade.
  • After becoming Venom's host, Setsuna's hero suit goes from purple to black.
  • Inverted with Fumikage. Instead of Moon Knight's well known white costume, he retains his canonical black outfit after becoming Konshu host.
• Adaptation Name Change: Several Hero Names change.
  • Aoyama goes by the hero name of "Radiant" instead of "Can't Stop Twinkling".
  • Mina gets to go by "Alien Queen" instead of having to pick "Pinky".
  • Momo goes by "Genesis" instead of "Creati".
  • Denki goes by "Raikou" instead of "Chargebolt".
  • Izuku goes by "Mischief" instead of "Deku".
• Adaptation Origin Connection:
  • Odin implies that an Infinity Stone may be responsible for the existence of Quirks.
  • It's mentioned offhand by Wolverine that people with Quirks, as they're known today, were originally simply called mutants.
  • During their conversation with Nezu, Thor and Loki reveal that the Dawn of Quirks, Beyonder attempted to use the power of the Infinity Stones to create the Battleworld, only to be stopped by the Avengers as well the Titans.
  • All of it is promptly clarified in Chapter 61. During the Secret Wars event, in order to prevent the destruction of their reality, the Avengers used the Infinity Stones to fuse their universe with the one it was in collision course with, in this case, the My Hero Academia universe, thus creating the Mischief universe.
• Adaptation Relationship Overhaul:
  • Since Mineta is not a hero student here, Denki is Izuku's friend and a member of his group instead of Bakugo's.
  • All of Tenko's relationships here, since he is a hero student. He is Izuku's friend, All Might's successor, and Tsuyu's love interest.
• Adaptation Species Change:
  • Izuku is half Frost Giant hybrid.
  • Himiko is a pseudo-vampire.
• Adaptational Badass:
  • Not only Izuku inherited his father's illusion powers, but he is also a skilled fighter and expert in knife-fighting. By the time of the Sports Festival, he also learned how to use his cryokinetic powers, courtesy of his Frost Giant ancestry. Izuku also possesses a scepter containing the Reality Stone as well.
  • Eri is trained by Izuku in order to learn how to defend herself, becoming a Pint-Sized Powerhouse Blade Enthusiast.
  • Tenko has been trained from a young age by Gran Torino, and he is the ninth wielder of One for All.
  • Being Thor's son, Denki not only can control lightning, but also has some degree of control over the weather, not to mention he has his own warhammer, Thunderstrike.
  • Tenya receives the Ebony Blade from Mephisto during the Internships arc.
  • After making a deal with Mephisto, Tensei Iida becomes the Ghost Rider.
  • Ochako gains the power of the Ten Rings during her fight against Gorr.
  • Momo is far more Strong and Skilled than her canon self thanks to her training with Izuku for the Final Exams.
  • Instead of being just poisonous, Mustard's gas causes hallucinations, and he also counts with several holographic drones similar to the ones Mysterio used.
  • Melissa wears a Powered Armor, alongside the Green Goblin's glider. She also has Pym Particles and a bow and arrow along.
  • Setsuna becomes the host of the Venom symbiote.
  • Kyoka gains Quake's gauntlets during I-Island, which not only increases the efficiency and power of her sonic blasts but also negates any damage to her sensible hearing.
  • Fumikage becomes the host of Konshu, making himself the next Moon Knight.
  • Shoji gains Whiplash's energy whips during his fight against Ultron, allowing him to attack from long-range as well.
  • Sero is bitten by a radioactive spider while Bakugo is accidentally injected with a Super Soldier serum vial based on Nitro, allowing him fire explosions from any part of his body, instead of just his hands.
  • Mei builds herself a Powered Armor with technology from all the Sinister Six members.
  • As a pseudo-vampire, Himiko has both super strength and regeneration powers.
• Adaptational Comic Relief: Shoto's Conspiracy Theorist antics make him even more The Comically Serious than he is in canon.
• Adaptational Early Appearance:
  • Izuku meets Aizawa before the Sludge Villain incident.
  • Izuku ends up running into and rescuing, Eri during the Sludge Villain Incident.
  • Lady Nagant is saved by Hirona after the Sports Festival.
  • Muscular debuts during the I-Island arc.
• Adaptational Heroism:
  • Tenko Shimura was saved by All Might and Gran Torino shortly after the incident that killed his family and is a hero student.
  • After being brainwashed into being Izuku's servant, the Nomu from the USJ becomes Eri's caretaker.
  • Danjuro Tobita is a Pro Hero called Gentle Hero and Manami Aiba is his sidekick.
  • Mr. Compress and Himiko are double agents working for Izuku from inside the League.
• Adaptational Jerkass:
  • Vlad King is so convinced that Izuku is a traitor that he orders his students to gang up on Izuku and force a confession out of him in the middle of the team battles at the Sports Festival. Luckily, Izuku's teammates save him. Ultimately subverted when it turns out is actually a Skrull pretending to be Vlad King.
  • Despite all his noble claims, Wolfram reveals himself as a Super Supremacist who wishes to get rid of the remaining Quirkless people left in the world.
• Adaptational Location Change: Due to Hirona's attack at the Pussycats base compromised the Beast Forest, Nezu arranges for the first-years' Training Camp to happen at Knowhere.
• Adaptational Modesty: After the Internships, Momo and Toru gain new hero suits made of Unstable Molecules that can adapt to go along with their Quirks and properly cover their bodies.
• Adaptational Nationality:
  • In addition to being a Half-Human Hybrid, Izuku is both half-Japanese, half-Asgardian. Denki is the same.
  • Instead of being just Japanese, Ken Takagi (formerly known as Rock Lock) is half-Japanese half-Wakandan.
• Adaptational Superpower Change:
  • Instead of receiving One For All, Izuku has Loki's Master of Illusion powers instead.
  • Tenko unlocks Blackwhip instead of Super Strength after gaining One for All.
  • Instead of being poisonous, Mustard's gas can cause hallucinations.
• Adaptational Sympathy:
  • In the Two Heroes movie, Wolfram was simply a mercenary seeking money by stealing the Power Amplifier, a very Flat Character. Here he is the leader of the Brotherhood of Mutants, grew up being persecuted for being different, and seeks to carry on Magneto's legacy. Ultimately subverted when he reveals himself to be a Super Supremacist even worse than Magneto who wishes to destroy the Quirkless because "their existence oppresses people like him."
  • Mustard's motivations for villainy are somehow vague in canon, with the closest thing to an explanation being he is resentful towards hero students for receiving proper training and control from schools. Here, he was locked in his house's basement from a young age since his parents were afraid of his Quirk.
• Adaptational Villainy: All for One finds Hana Shimura in the aftermath of her family's destruction, resulting in her being groomed into villainy as Hirona Shigaraki.
• Age Lift: Tenko is 15 years old here, instead of 20.
• Alas, Poor Villain:
  • Zigzagged. While most of the gods from Omnipotence City most likely had their punishment coming (they were going to execute Stain for simply entering the city) you can't but feel sorry as they are all brutally slaughtered by Gorr. Special mention to Zeus who dies while holding Hercules' dead body in his arms.
  • Played Straight with Sam. The poor guy can only cry and beg for help as Ultron melts his skull off with his Eye Beams, and his best friend can't do anything but watch. That's a particularly cruel and sad way to die for someone who was Only in It for the Money.
• Alien Non-Interference Clause: Odin's Law, which prevents Asgard from interfering with any conflicts of the Nine Realms. Breaking it is considered treason, no matter for what intention. As Heimdall unfortunately finds out after I-Island.
• All Animals Are Dogs: The Nomu behaves a lot like a monstrous super-powered dog after becoming Izuku's pet.
• All Your Base Are Belong to Us: Played With. As Hirona points out, the League's invasion at Knowhere is not to take the station, kill the heroes, or even win, but to take and punish who they think deserves. As such, they destroy the Spirit Tree, cause a prison riot, and use the Nomus and their members to wipe out any resistance on their way.
• Always Someone Better: One of the sour points for Hirona is that they are always compared unfavorably to their brother by All for One.
• Amazingly Embarrassing Parents: Loki and Inko are this to Izuku, best shown during the Sports Festival. Thor and his wife are the same to Denki.
• …And That Little Girl Was Me: Thor attempts to invoke this during his talk with Denki by recalling the story of a "certain spoiled brat prince who was immature, brash, quick to anger, and thought himself above others that learned that before becoming a great king, he needed to be a good man" but accidentally falls halfway through it by referring to himself during said talk. Nevertheless, Denki understands what his father means, and thanks him for the advice.
• Anti-Villain:
  • Loki seems to be a Well-Intentioned Extremist variety, given his regret over how much his family will be hurt by his actions, but believing it to be a necessary sacrifice for the greater good.
  • Hirona is a combination of the Noble Demon and the Woobie variety. She wants revenge against Tenko for killing her, the society that left her saved him and not her, but is very clear deep down she doesn't fully hate him. It is also clear she hates to work for All for One who brought her back to life and is using her as his weapon.
  • David, per canon. His attempts to help the world and keep the peace All Might built are rooted in genuine good intentions. Unfortunately, this leads to the of a monstrous A.I. that seeks the end of humanity. This is eventually subverted, when it's revealed that the real David has been replaced by a Skrull.
• Arch Nemesis Dad:
  • Loki is being set up to be this to Izuku.
  • Ultron is this towards Vision, his creation.
• Arc Villain:
  • The Beginnings arc has the Sludge Villain and the Yakuza thugs as Starter Villains of the story.
  • The USJ has Hirona Shigaraki as the leader of the invasion, but the Kurse Dark Elf acts as the main threat to Izuku.
  • The Internships arc has Stain, the Hero Killer, and Gorr, the God Butcher
  • The Final Exams have the teachers acting as opponents against the students until they are defeated halfway through the arc and are replaced by Hawks.
  • At first, it seems that the Brotherhood of Mutants led by Wolfram will be the main antagonists of the I-Island arc, only for Ultron to reveal himself and hijack the arc as the main villain of it before it even begins.
  • The Guardians Training Camp arc has the Vanguard Action Squad attacking Knowhere, with Kraven, Taskmaster, and Daken standing out as the most dangerous enemies, in addition to the Nomus that weren't used in Hosu.
• Armor-Piercing Question:
  • Izuku gives one to Nighteye, making him realize that for all his plans for when Mirio accepted One for All, he never once considered if Mirio would accept the Quirk, which he doesn't.
  • He later gives one to Tenya, asking him if he would let something implied on the rules stop him from saving people.
• Armor-Piercing Response: Tenko gives one to Hirona while calling the villain out on how her revenge quest against him and All for One is causing more harm than good to those around her.
  Hirona: I don't want this! I want to be free! That's it. That's all I want. I just want to be free of him. Is that... (her voice lowers to a whisper) Is that too much to ask?
  Tenko: If you keep going down this path... you'll never be free of him.
• Artifact of Doom:
  • Izuku's scepter, which contains the Reality Stone, is the most powerful weapon in his arsenal. It's also highly dangerous and without proper training and control, it can turn its user into a Drunk with Power megalomaniac.
  • The Ebony Blade is the same thing. If the wielder is weak-minded, the sword will take control over them and turn the person into a mindless killing machine.
• Ascended Extra:
  • Denki is far more prominent in the story than his canon counterpart, being one of Izuku's friends and his cousin.
  • Hana Shimura is brought back to life, and is one of the story's main antagonists.
  • The USJ Nomu, thanks to being brainwashed into being Izuku's servant, not only remains in the story after the USJ arc but also becomes Eri's caretaker and bodyguard.
  • Tensei Iida becomes a member of the U.A. staff after the events of Hosu.
  • Melissa Shield and Setsuna Tokage become recurring cast members after the I-Island arc.
• Ascended Fanboy:
  • Ochako is a huge lover of anything related to space, so Izuku makes her dream come true by taking her to Asgard during their first date.
  • Both Ochako and Mina get to live this dream when the hero students are taken to Knowhere for the Guardians Training Camp.
  • Deconstructed with Fumikage. Despite being a Chuunibyou and 1-A's resident lover of macabre, his possession at the hands of Khonshu happened during Near-Death Experience, where neither he nor Dark Shadow had the power to decline the deity's help, not to mention that said "partnership" is way more beneficial towards Khonshu than him, and if Fumikage decides to end said "partnership", the hero student will be left in a near-death state where he was found.
  • Setsuna, the resident reptilian enthusiast gets to live her dream to meet living dinosaurs when Denki arranges for their first date to happen at Savage Land.
• Asshole Victim:
  • Zigzagged with the gods of Omnipotence City, who were more than willing to execute a human (Stain) for simply getting lost in their city.
  • Played Straight with Wolfram and Muscular. While gruesome, no one will feel sorry for a bigot being lobotomized and brainwashed, or a psychotic killer being left paraplegic.
• Assimilation Plot: Ultron's Evil Plan. Using a virus named after him, the android intends to cyberform anyone that comes in contact with it, turning its victims into extensions of his conscience.
• Astral Projection: Amongst the powers Izuku inherited from Loki, the ability to project his consciousness of his body is one of them.
• Atrocious Alias:
  • Besides "King Explosion Murder" and "Lord Explosion Murder", Bakugo came up with "Darth Explosion Murder" for his hero name choices. And of course, it got rejected.
  • Rocket's original suggestion for the Guardians team name was "Ass-Kickers of the Fantastic".
  • As Izuku points out during their fight, Mustard's villain name is more likely to bring the condiment to mind rather than the toxic gas, which pretty much ruins any of his attempts to come off as fearsome and badass.
• Audience Surrogate: Many readers consider Shoto this, given his Conspiracy Theorist goes in line with how fans often debate over all the mysteries surrounding the story.
• Attention Deficit... Ooh, Shiny!: Invoked by Thor in order to help Aizawa deal with Izuku. According to him, there are three methods to help distract the young trickster: First, distract him with something to occupy his mind, whether is a task or appealing to his inner hero fanboy; Second, direct him to someone else and pray for forgiveness later; the final one is to tease him about Ochako, but this one is not completely foolproof.
• Author Appeal:
  • Hirona's love for movies is inspired by KageNekem's own love for cinema.
  • KageNekem is a massive Star Wars fan and an avid Yu-Gi-Oh! player, so he always makes sure to add several references to both franchises in the story.
  • The author is also a fan of badasses in suit who are dressed to kill, so he always makes sure for his characters, especially Izuku and Loki, to look as dashing and badass as possible in his descriptions.
  • Hilariously averted with his food taste. KageNekem hates black chocolate, often having characters describing it as gross and saying white chocolate is better. He even has Tenko dust a black chocolate bar in chapter 60 just because.
• Back from the Dead:
  • Loki was the one to bring Hana Shimura back from the dead using the power of the Soul and Reality Stones.
  • Somehow, Ultron was brought back into existence, although it's not clear if David Shield is the one responsible for it. Ultimately subverted since according to him, Ultron never died to begin with.
• Badass Boast:
  • Izuku delivers the opening quote of the page before taking on the villains of the USJ.
• Bait-and-Switch: Briefly during Chapter 8, and later in Chapter 29, Izuku is watching videos from Gentle's channel. At first, it may sound odd for a hero student to watch a villain's channel, only for Chapter 35 to reveal that Gentle is actually a hero in this story.
• Bait-and-Switch Boss: For the I-Island arc, it seems like Wolfram and his newly formed Brotherhood will be the major threat during the Expo only for the ending of Chapter 48 reveal that honor will go to none other than Ultron.
• Barrier Warrior: Besides Gentle, Hirona's Quirk, Force Field Manipulation, allows her to create air membranes that can act as barriers and platforms.
• Bash Brothers:
  • Ghost Rider and the Nomu, against all odds.
  • All Might and Thor after the Final Exams.
• Batman Gambit:
  • Izuku pulls one during the Sports Festival: Realizing his team is at a disadvantage, he has Mei hit Shoto's team with a flashbang grenade, and in the middle of the confusion shapeshifts himself and his teammates into Todoroki's teammates and vice-versa. This causes Todoroki to freeze his team and nearly gets him knocked out by Izuku's.
  • Izuku does it again in order to defeat Gorr near the end of the Internships arc: After Stain gets his Heel Realization, he stabs Gorr and paralyzes him, while Izuku shapeshifts into Gorr's daughter and tricks him into handing over the All-Black symbiote.
• The Bad Guy Wins: Twofold. Despite the heroes and students best efforts, this is how the I-Island arc ends: While all his physical bodies are destroyed, Ultron successfully uploads his consciousness inside the I-Island computers, destroys the last evacuation ship, leaving Izuku and his friends stuck on the island just as the military launches a bombardment to destroy the place and prevent Ultron's escape. Even that fails because Loki arrives in the last moments to help the AI escape and promises to provide him a more powerful body in exchange for his help with his plans, making all their efforts, as well as Izuku exposing his secret as an alien All for Nothing.
• Beethoven Was an Alien Spy: Discussed. Knowing aliens exist, Denki wonders if Jesus was one and Izuku admits he cannot disprove that.
• Beyond the Impossible: Doctor Doom is capable of not only detecting Izuku and Strange's presence on his castle from inside the Mirror Dimension as soon they teleport to it, but promptly kicks them out of said castle without even showing his face.
• Big Bad Wannabe:
  • Wolfram. At first, it seems like he is a strong and fearsome leader of the Brotherhood of Mutants, ready to carry out Magneto's legacy, only for him to be immediately Demoted to Dragon once Ultron makes himself known.
  • Mustard. He attempts to come off as the ultimate Master of Illusion, superior to Izuku in every possible way and a villain that should be feared as much as anyone, but despite all his preparations and upgrades, as well his claims of superiority, he barely qualifies as an Unknown Rival.
• Big Damn Heroes:
  • Multiple times during the Hosu arc. First Tenko arrives to save Tenya from Stain, followed by Izuku and Shoto, then followed by Tensei, as the Ghost Rider, who takes on Gorr, then by Denki, Ochako, and Mirio.
  • Mei and her Iron Man-controlled suits arrive just in time to save the hostages at the I-Expo from being executed by Ultron and the Iron Legion, even though they fail to save Izuku, All Might, David, and Vision from being taken.
  • Heimdall uses the Bifrost to save the Heroes and students from I-Island just as all of them are about to die.
  • Himiko and Compress arrive just in time to save Izuku from being overwhelmed by Mustard's illusions during the League's attack in Knowhere.
• Big Damn Kiss: Izuku and Ochako have theirs during chapter 43.
• Birds of a Feather:
  • Eri and Laura bond over their traumatic childhood of being experimented on by mad scientists and their love for... stabbing bad guys.
  • One of the reasons the Vestiges try to keep Tenko from meeting Yoichi is because they are very likely to bond, and eventually waste time, over their love for video games.
  • Daken and Dabi bond over the fact both of them want to kill their fathers.
  • Nezu and Rocket immediately hit a partnership over their past of being experimented on in labs, being super intelligent Animal Super Heroes, and lead their respective groups.
  • Shoto ends up befriending Quill upon finding out that he also has issues with his Abusive Parent and was the product of a Super Breeding Program.
• Bizarre Taste in Food:
  • Shoto says he enjoys black olives in pizza. Izuku cannot help but feel betrayed by his friend's weird taste.
  • Tenko seems to be the only person in Mischief Squad who likes dark chocolate and finds anyone who likes the white one crazy. This one is an inside joke between KageNekem and his editor JustaPerson1.
  • Tenko has the habit of mixing coffee with energy drinks just as he wakes up. Hitoshi, who also loves coffee (but pure) can't help but stare in a mix between horror and amazement over witnessing it.
• Black-and-White Insanity: Vlad King is so adamant about Izuku's alleged connection with the League, that he pretty much gets Monoma and other 1-B students to go on a witch hunt against Izuku during the Sports Festival and try to force a confession out of him, which only fails because of the timely arrival of Izuku's team.
• Blade Enthusiast:
  • Izuku inherited his father's love for daggers and blades. He even learned how to shapeshift into a swordfish solely because it is an animal that can stab people.
  • Eri started to share Izuku's love for blades as well, carrying a pair of retractable ones on her wrists.
• Bloodier and Gorier: The I-Island arc becomes this with the arrival of Ultron, who promptly executes Sam and all the Brotherhood mercenaries attacking the gala.
• Blood Sport: It is a costume that every time I-Island passes by Japan, they "loan" a dangerous inmate from Tartarus for some kind of modern high-tech gladiator battle. The prisoner chosen for this year's was Muscular.
• Bond Villain Stupidity: Hirona gloats to Izuku about how the Nomu only obeys her commands. This prompts the boy to shapeshift into her and take control of the monster. First to attack her in order for him to escape, and later into obeying Izuku and only Izuku.
• Boom, Headshot!:
  • How Taskmaster kills Shishido in Chapter 49.
  • Wolfram executes Miura Takashi, the head of the I-Island Board of Directors like this when the man refuses to give him access to the vault and the inventions inside of it.
• Borrowed Catchphrase: Izuku borrows Loki's introduction line "[...] and I am burdened with a glorious purpose" as part of his Badass Boast at the USJ.
• Brainless Beauty: Zigzagged. Shoto is by no means an idiot, but he is definitely socially inept to come off as such. The below line explains best:
  Toru: No, I mean, what do you think about you and Midoriya dating?
  Shoto: Dating? What would we be dating exactly? A tree? Artifacts? Artifacts of alien nature perhaps? Dating them could be useful to figure out how long extraterrestrials have been on Earth.
  (Collective Head Desks)
  Toru (sighing): Be glad you're pretty…
• Bread, Eggs, Milk, Squick:
  • Eri's morning routine: Watching cartoons, playing with toys, practicing her stabbing technique, and drawing. Also when Mic tells her she can't practice with her knives until Aizawa comes back, she does what Izuku told her: Smile sweetly, say okay, and then go grab one of the knives they had hidden in her room.
  • Mei lists all the things she brought along for the Festival to help Izuku's team.
    Mei: Hover boots, nets, jet pack, sludge pills, tasers, death ray-oh darn, Power Loader took that one out- flash bangs, smoke bombs, pretty much any bomb you can think of!
  • Izuku lists all the utilities of Hitoshi's Brainwashing for pranking, such as making Bakugo compliment everyone while they film it, or make Monoma copy Awase's Quirk and make him stick himself somewhere embarrassing, or make Endeavor walk into traffic.
  • Taskmaster, makes a point of what kind of questions he doesn't bother wasting his time with:
    Taskmaster: I make it a point not to waste my breath with stupid questions. If you'd like other examples, they include: 'Where did you come from?' 'Who sent you?' And 'Please don't kill me.'" (Beat) I suppose the last one isn't a question, but you get the point.
• Breaking the Fourth Wall:
  • Before finishing his call with Izuku in chapter 19, Deadpool tells the boy to say hello to the readers.
  • He also makes a cameo in chapter 59, releasing several explicit fanfics supposedly written by Endeavor, saying "Don't tell anyone so I can surprise the readers later."
• Breather Episode: Each arc has a small arc to fill gaps between the next ones, mostly composed of Slice of Life and setting for upcoming plotlines:
  • Chapters 16 to 20 act as one between the USJ and Sports Festival arc.
  • Chapters 41 to 44 are one between the Internships and the Final Exams arc.
  • Chapters 59 and 62 fill the gaps between the I-Island and Guardians Training Camp arc.
• The Bus Came Back:
  • Hiromi Yoshinaga, the girl with a demon-like appearance that Izuku saved from bullies when he was young appears back in chapter 36, having become a Bully Hunter herself.
  • The bull-headed villain that Loki beat up in the first chapter returns in chapter 50.
• Butt-Monkey:
  • Bakugo was and still is the main target of Izuku's pranks.
  • Endeavor has become one as well, especially after Izuku finds out about his family life.
  • Monoma became one after Izuku got tired of his taunts against 1-A.
• Cain and Abel:
  • Loki and Thor will inevitably become this when the God of Mischief's plans are revealed.
  • Tenko is the Abel to Hirona/Hana's Cain.
  • Izuku and Sleipinir are Abels to Fenrir's Cain.
  • Daken is the Cain to Laura's Abel.
• Call-Back: Chapter 50 has several to the first chapter, from Izuku dramatically introducing himself with his "Glorious Purpose" line upon arriving at a restaurant, only to be received by an unimpressed waiter, to the blue snakes he uses to scare everyone up, and finally, the bull-headed villain that his father beat up years prior showing up for a "rematch" and ending with Izuku saying "but where is the fun in that?".
• Canon Character All Along: As it turns out, Himiko was the pink-haired girl in the orange sweater that talked to Ochako about embracing her feelings and admitting her feelings for Izuku during the Sports Festival in Chapter 25, and her partner, the plain-looking man with brown hair was actually Compress out of costume.
• Cassandra Truth:
  • Even though everyone knows Izuku is a Bad Liar, nobody believes him when he says his powers are magic.
  • At some point in the past, Nagant killed a Commission employ that discovered the Skulls had infiltrated the organization, but dismissed it when the person said that it was part of an alien invasion.
• Cast from Lifespan: Word of God mentions in one of the comments that the life force draining aspect of OFA on quirked people is not being adapted out. This is finally revealed during a training exercise after Hosu, as Tenko spits blood during a coughing fit that OFA is beginning to affect him.
• Cerebus Retcon:
  • Loki's suggestion for Izuku to use the Bifrost to prank his teachers eventually becomes this when he reveals to Ultron it was part of a subliminal idea for Izuku to unintentionally force Heimdall to interfere with a crisis on Earth (in this case, the destruction of I-Island) and get the watcher removed from his post, thus helping his and Thanos's agenda.
  • While at first, it seems like Inko scolding Izuku to not take his pranks too far seems like a reasonable lesson from a parent to their child, it's actually pointed out that the last time one of Loki's pranks went too far (he faked a bomb explosion in New York) it caused the Hulk to go on a rampage and got several people injured.
• Chekhov's Gag: During the Guardians introduction in chapter 64, the main attribute used to describe Cosmo is "Absolutely will read your thoughts without permission". This comes full circle by the end of the chapter, when the telepathic dog finds out that Aoyama is the U.A. Traitor.
• Chekhov's Gun:
  • The Dark Elf's sword and rifle that Izuku acquires after the USJ. Izuku keeps the sword and later uses it during his fight against Stain, while the rifle ends up in Mei's hands, who reverse-engineers it and uses it during the Battle of Hosu.
  • The Ten Rings. They are only mentioned briefly during the beginning of the Hosu arc before Gunhead grabs and handles them to Ochako during the Berserkers' invasion. Ochako manages to activate them to save Izuku while facing off Gorr.
  • During their three-way fight, Nagant fires a bullet with Knock Out Gas against Gentle, who manages to seal it in one of his membranes. Said membrane is destroyed by the Ghost Rider's flaming vortex, and the gas is inhaled by Stain.
  • Several items that made a cameo in chapter 48 return throughout the I-Island arc. The Venom symbiote attaches itself to Setsuna; Mei builds herself an armor made from items of the Sinister Six; Sero is bit by a radioactive spider and Bakugo is injected with a Super Soldier serum made from Nitro's power.
  • The blue marbles that Izuku carries around and gave to his friends in Chapter 50 all have small tracking devices that he uses to find his classmates during the League's attack in Knowhere.
• Child of Two Worlds: Izuku, much like his father, has split ancestry. His father is Asgardian royalty, while his mom is an unassuming woman from Earth. Izuku has been primarily raised on Earth and seeks to become a hero there. Denki also counts, being Thor's son.
• Children Forced to Kill: Going by canon's timeframe, Hirona was somewhere between 8 and 11 years old when she killed her first victim. Since at that time, she wasn't skilled enough to make the edge of her barriers sharp enough, she essentially bludgeoned a (possibly) innocent man to death.
• Clark Kenting: Nemuri's lover Colossus is unable to recognize her when she is in costume and she wants to see how long it takes him to connect the dots.
• Cold-Blooded Torture: The facility where Himiko was trapped in since she was six years old forced her to undergo inhuman experiments to test out her pseudo-vampire powers.
• Composite Character:
  • Loki is Izuku's father here, and Hisashi Midoriya is simply one of his aliases.
  • Hirona Shigaraki takes Tenko's place as All for One's apprentice and leader of the League.
  • Logan is a fusion between the movie and the animated series interactions of his character.
  • While Gorr is mostly based upon the MCU version of his character, the story version of him and the Necrosword are connected to Knull and the symbiotes, which didn't happen in the movies because the rights to the latter are held by Sony.
• Compound Title:
  • Chapters 10 and 11 are titled "This is Getting Out of Hand" while chapters 14 and 15 are titled "Now There Are Two of Them", the full sentence was spoken by Viceroy Gunrey in The Phantom Menace
  • Chapter 33 is titled "Speak of the Devil", while chapter 39 is titled "And He Shall Appear". Meaningfully enough, the former is the episode where Mephisto is introduced, while the latter is where he reveals his true identity.
  • Chapter 61 is titled "Reality Can Be" while chapter 62 is titled "Whatever I Want".
• Conditioned to Accept Horror: Shoto is not all phased during the attack on I-Island. As he points out after the USJ and Hosu, Class 1-A being stuck in the middle of villain attacks has become quite mundane. His classmates agree.
• Confusion Fu: Much like Loki, Izuku's fighting can be described as such. Since his illusions are not particularly powerful, when facing an opponent, Izuku relies on making decoys of himself, shapeshifting, invisibility, trash-talking, and tossing as many knives as possible. This becomes deconstructed during his match against Denki at the Sports Festival. As his friend points out, "being unpredictable, makes him predictable" meaning that he needs to learn to adapt and use every tool and knowledge of his arsenal in a fight, not just what Loki taught him. Reconstructed during his internship with Gentle, where Izuku learns how to integrate his scepter and ice powers as well, to his original fighting style, improving it immensely.
• Conspiracy Theorist: Shoto, per usual. Aside from his "secret love child" gag, he also does a lot of research about magic and alien subjects.
• Continuity Nod: Izuku and Ochako have a discussion in Chapter 65 over how it would be if The Multiverse was shaped like a tree, with each of its branches being a different reality, almost like Yggdrasil. Izuku considers it to be a rather sad idea if it were true, since the main point of Yggdrasil is a single person, watching and guarding all of its worlds, all by themselves. That happens to be Loki's fate by the end of Season 2, the lone watcher, guarding all the realities of the Multiverse as the God of Stories.
• Conveniently Unverifiable Cover Story: Lampshaded by Nezu himself. The official explanation for Tensei's transformation into Ghost Rider is that at some during the attack on Hosu, Tensei was attacked by a Black Berserker and it somehow led to his Quirk mutating into his current state. Since all Berserkers were destroyed with Gorr's defeat, there is no way to clarify its veracity.
• Cool Uncle: Thor is this to Izuku. Logan and Deadpool count as honorary examples.
• Cult of Personality: The High Evolutionary has one in the remnants of the Orgocorp, a fanatical cult dedicated to continuing his unhinged vision to create "a perfect universe". They are the ones responsible for smuggling the League to Knowhere during the Guardians Training Camp arc.
• Curb-Stomp Battle: Loki versus that Villain trio in the first chapter is so one-sided Loki uses them to teach his son a lesson in using their powers.
• Curb Stomp Cushion: Hirona versus the Pussycats. While the heroes put on a brave fight when the girl attacks their compound, Hirona still manages to defeat all of them.
• Crippling Overspecialization: Izuku suffers from a case of this due to his blind worship of Loki, relying solely on his father's teachings, such as working alone, relying on his tricks, and trying to control all variables in the field. This comes back to bite him during the Sports Festival when Monoma and other 1-B students gang up on him and nearly beat him down to get a false confession over his alleged connection with the League. This also costs him during his match at the Finals, because as Denki points out, being unpredictable makes him predictable. Interestingly enough, it is by going against his father's wishes and learning how to control his Cryokinesis, that he manages to beat Shoto, which marks another step for his Character Development.
• Crossover Couple:
  • Given the premise of the story, Loki is married to Inko Midoriya and is Izuku's father.
  • Thor is married to Denki's mother, although since she never appeared in canon, she is more of a Canon Foreigner.
  • Piotr Rasputin/Colossus is Midnight's boyfriend, although he doesn't know Nemuri Kayama's secret identity.
• Crossover Power Acquisition: Several MHA characters gain access to abilities or items from the Marvel Universe.
  • Tenko's hero costume features several Stark technology gadgets.
  • Ochako gains the power of the Ten Rings.
  • Tenya receives the Ebony Blade.
  • Tensei is the new Ghost Rider.
  • Melissa uses the Green Goblin's glider amongst other gadgets, as well as Pym Particles.
  • Setsuna becomes Venom's new host during the I-Island arc.
  • Kyoka has Quake's gauntlets.
  • Fumikage is the next Moon Knight.
  • Shoji gains Whiplash's energy whips.
  • Sero is bitten by a radioactive spider.
  • Bakugo is accidentally injected with a Super Soldier based on Nitro's power.
• Crossover Relatives:
  • The main premise of the story is that Izuku is Loki's son.
  • Denki is Thor's son, and by extension, Loki's nephew.
  • As it turns out, Shinso is related to Kevin Thompson/Killgrave.
• Crossover Villain-in-Chief: Most, if not all Marvel villains count as such. While All for One remains just as menacing as he is in canon, his power level pales in comparison to cosmic threats like Gorr, Thanos, Mephisto, and Ultron.
• Cruel and Unusual Death:
  • Yoroi Musha is ripped to pieces by Gorr's Black Berserkers.
  • Ultron kills Sam Abraham by slowly melting his skull with his laser eyes until the scientist's brain explodes.
• Daddy Had a Good Reason for Abandoning You: Thor blames the long list of enemies he made as Prince of Asgard and as an Avenger for not being able to be present in Denki's life growing up. Eventually, thanks to Loki's reasoning, plus Izuku's influence and just missing his family, he lets go of this fear to try and reconnect with them.
• Dancing Royalty: Downplayed for now with Shoto, but Quill has promised to give him dancing lessons to help him become less stiff, both to serve as a distraction in a fight as well as for the boy to loosen up a bit. If his unintentional demonstration to Kyoka and Momo serves as any indication, Shoto might actually become this eventually.
• Deadly Dodging: Izuku tricks Bakugou and Kirishima into attacking each other by having his clones dodge when the other two are in position.
• Deal with the Devil:
  • Played for Laughs. After giving Mei the plasma rifle from the Dark Elf from the USJ, Izuku can't help but feel that is exactly what he did.
  • Played Straight during the Internships. In order to save Tenya from being killed by Gorr and Stain, Tensei accepts a deal from Mephisto and becomes Ghost Rider.
  • Played With when it comes to Khonshu. He claims to have noble goals, but he still specifically approached Fumikage to become his new host and carry out his will while the boy had no position to refuse it, with a bullet wound in the stomach. Not to mention the God also would have no problem with leaving both Fumikage and Dark Shadow exactly as he found them back during Ultron's attack.
• Deadpan Snarker: Izuku has inherited his father's dry sense of humor.
• Death by Adaptation:
  • The gods from Omnipotence City are still alive in the MCU. Here, they are all killed during Gorr's rampage.
  • Yoroi Musha is torn to pieces by Gorr during the attack on Hosu.
  • Shishido is killed by Taskmaster due to a bounty on his head.
  • Sam Abraham has his skull melted down by Ultron.
• Did You Just Flip Off Cthulhu?:
  • Izuku gives Gorr a massive "The Reason You Suck" Speech, calling him out on his hypocritical rampage, saying he is even worse than the gods he murders.
  • The young trickster does it again with Ultron during the I-Island arc, when his forces begin to be overwhelmed by the hero students, by pointing out that for someone who hates humans so much, his behavior is awfully similar to one.
• Distracted by the Sexy:
  • During the Battle Trials, Izuku is distracted enough by Ochako's costume that he missed the signs Denki has magic like him.
  • Shoto tries to show off some of the dancing moves that Quill taught him to Momo and Kyoka. Cut to both girls being stunned and blushing messes due to his display of "pelvic sorcery".
• Enemy Mine: Hirona and Nagant are forced to work alongside Nejire during Gorr's attack on Hosu.
• Evil Cannot Comprehend Good:
  • While seeing Ochako trying to defend Izuku by any means necessary, Gorr believes that it must be some kind of enchantment from the demi-god, instead of genuine love between both teenagers.
  • Mustard does not understand why Izuku did not use his illusion powers to cause his opponents traumatizing hallucinations in order to win his fights at the Sports Festival.
• Evil Smells Bad: Inverted. Mustard's illusions carry their victims' favorite smells, like Inko's Katsudon to Izuku, a box of Mochi to Ochako, or Tensei's cologne to Tenya.
• Even Evil Has Standards:
  • While Hirona takes Kota hostage in order to force Ragdoll to give her Nagant's location, as soon as the hero complies, she releases the boy, saying she doesn't hurt kids. She also doesn't let Kurogiri take Ragdoll to All for One to steal her Quirk, even though she is in a perfect position for it.
  • Stain will kill a minor if they demonstrate they are what a hero should not be, but he doesn't specifically seek them out to slay. This is one of the reasons that leads to his Heel Realization, as Gorr will kill anyone, adult or child for the sake of his sadistic quest.
  • Once she finds out that Aoyama is only acting as their mole for the safety of his family, Hirona refuses to rely on him any longer, even if it means asking for Loki's help to find the camp, arguing that would make her no different of All for One and his Manipulative Bastard attitude.
  • Nagant and Hirona are positively creeped out by the High Evolutionary's Cult of Personality and make sure to interact as little as possible with them during the trip to Knowhere. That doesn't stop Daken from flirting and sleeping with the crew members, however.
• Every Man Has His Price:
  • Nighteye only manages to convince Gran Torino to U.A. and check Mirio for a possible candidate for One for All after bribing him with tayaki and a car to take him to the school.
  • While planning on how to get the teachers' schedule over what the final exams will be about, Izuku bribes Kyoka with tickets for Luna Snow's concert. She agrees.
  • Izuku attempts to bribe Hawks during the Final Exams by promising to buy KFC (his Trademark Favorite Food), and rebrand it as "Endeavor Fried Chicken", and use a Colonel Sanders-dressed Endeavor as its mascot. With or without the Flame Hero's consent, mind you.
  • Loki manages to secure Ultron's help for their alliance with Thanos by promising him not only access to Adamantium and the Sentinel Project, but also access to the Odin Force, which will effectively make the android a omniscient being, once Odin is dead and Asgard has been destroyed.
  • Izuku and Momo attempt to bring Itsuka to their respective factions of the Prank War with different promises: Izuku and Momo promise to buy her a new motorcycle, Momo promises a customized one; Izuku promises to have Mei make new parts for the one Itsuka is working at, Momo says she will make the new pieces on spot, and so on.
• Evil Is Not a Toy: Much like Hank Pym before him, David Shield attempted to use Ultron as a means to preserve the world's peace once All Might is gone. As soon as the scientist activates it to save him and his friends from the Brotherhood mercenaries attacking I-Expo, the malevolent A.I. immediately betrays his resurrector and sets in motion his plan for the extinction of humankind.
• Evil Is Petty:
  • All for One went to a new level of pettiness to mess with All Might and Tenko. As if it wasn't enough to turn Hana Shimura into a villain, All for One gave the girl a villain outfit that looks exactly Nana's original costume, and since Hana is the spit image of her grandmother, as soon as All Might lays eyes on her during the USJ, he mistakenly confuses her with his dead master.
  • Mephisto only chose to go give Tenya the Ebony Blade because he is good friends with Izuku, and he wanted to get revenge on Loki by targeting his son's friends.
• Eviler than Thou: Ultron does this during the I-Island arc by lobotomizing Wolfram and killing almost all Brotherhood mercenaries that invaded the gala.
• Exact Words: Loki, and later Izuku, are very careful with their word choices, being technically correct while still hiding the truth of their actions.
• Faking the Dead: According to Loki, that is how Thanos avoided being captured by the Avengers after Beyonder's defeat.
• Fighting Across Time and Space: Izuku and Stange's duel in chapter 62 jumps back and forth across several locations from the Marvel Universe. They start at the Avengers facility, then to New York, Savage Land, The Raft, Atlantis, Joutunheim, the Sanctum Sanctorum, Latveria, a SHIELD Helicarrier, and back to the Avengers base.
• Freudian Excuse Is No Excuse:
  • Izuku acknowledges that while the gods' treatment of Gorr and the death of the villain's daughter were horrible and he did not deserve it, it's not enough to justify his Roaring Rampage of Revenge.
  • After defeating Mustard and witnessing his Villainous Breakdown, Izuku states the other boy is not blamed for his Quirk being seen as villainous nor being mistreated because of it. He is, however, fully responsible for his actions after fully embracing villainy.
• Friendless Background: Most of Class 1-A and Mischief Squad students share this in common. Izuku because nobody wanted to be friends with someone with a Quirk too weak for heroics; Ochako because she was poor; Fumikage because people were creeped out by his and Dark Shadow's appearance as well as his gothic personality; Momo because most people only saw her as means to get through her family and their wealth; Shoto because Endeavor never saw the point of letting him get close to others; and Hitoshi because of his "villainous Quirk", and the fact he is a descendant of Killgrave.
• Foreshadowing:
  • Shortly after the Battle Trials, Denki mentions having a cousin that he hasn't met yet. The description also mentions his eyes are blue instead of golden like in canon. Later chapters reveal this is a case of Strong Family Resemblance between him and his father Thor, making Izuku the cousin he didn't knew about.
  • Izuku's scepter being the Reality Stone. While temporarily corrupted by the stone's influence, Decoy Two manages to become physical to snap Izuku out of his trance. During his meeting with Nezu, Thor mentions that the Reality Stone is the most dangerous of the Infinity Stones not only because of its Reality Warper abilities but because it is capable of corrupting its users by feeding on their darkest desires.
  • Prior to the Festival, Izuku mentions that Heimdall took him to Antarctica for special training and that he also has been using Lunch Rush's empty freezers to try this new training. His match with Shoto reveals that Izuku was trying and successfully managed use the Cryokinesis powers from his Frost Giant heritage.
  • Moon Knight's appearance. During the I-Expo, Izuku and Denki mention they somehow got lost next to the Egyptian Exhibition, and after Fumikage is shot by Ultron, both he and Dark Shadow notice that the Moon seems to shining brighter. In the following, Salem, an Egyptian hero, is shown to be praying to the Moon, or more likely, Khonshu.
  • Several to the reveal that Himiko and Compress are not villains in the story, as well as they being friends with Izuku.
    • The marbles that Izuku carries around school and ends up giving the rest of Mischief Squad during their trip to the mall in Chapter 50 are similar to to the ones Compress uses. That's because they are the exact same.
    • Back in when he was accused by Monoma of knowing villains, Izuku said he was not a traitor not that he didn't spoke to villains, which both the vampire and the magician fall under. Also, when he was questioned by Shoto over about knowing vampires, Izuku subtly changed the subject without actually answering the question. That is also the subject that Tensei, or rather the Rider, wanted to talk to him in the hospital back in Chapter 41..
  • In Chapter 51, Loki mentions he is well aware Izuku is spending money in some project involving fake companies, a blood donation center and a bank. Izuku bought a blood bank to provide free blood to Himiko so she won't have to retort to attacking people.
    • While attending Vesla Dran's wound, Compress mentions he is well trained into assisting with stab wounds, which can mean he learned from being around Himiko but also with Izuku.
• For the Evulz: Mephisto explains that his reason for giving Tenya the Ebony Blade is to get revenge on Loki, by targeting one of his son's friends, and because he likes to mess with humans.
• Fun with Acronyms: Mina, Toru, and Decoy Thirteen set up an "official" organization for Shippers on Deck to help their classmates find romance and Mina cleverly calls it Strategic Help for the Infatuated Program. Yui is their first new member.
• Fusion Fic: At first, it was one between My Hero Academia and the Marvel Universe, more specifically the MCU versions of the characters, although later chapters include characters that have yet to be adapted by the movies, like the X-Men. Taken to a literal extent when turns out this reality is a fusion of the Marvel Universe, and the MHA Universe, created by the Infinity Stones during the Secret Wars event centuries prior.
• The Gadfly:
  • Izuku. Being the son of the God of Mischief leads to him taking fun by getting on people's nerves.
  • Tsuyu is this, mainly towards Tenko. She is well aware he has a crush on her, and the feeling is mutual, but that doesn't stop her from endlessly teasing him.
  • As expected from the God of Mischief, Loki always has fun at the expense of others, especially Ebony Maw.
  • While all the modern-day Avengers love to mess with Strange, Miguel is always the biggest example of it.
• Game-Breaker: In-Universe example. Upon understanding the potential Decay has for good, plus One for All, Tenko considers himself a living cheat code, which also leads to him choosing "Cheat Code" as his hero name.
• Generation Xerox: Izuku is one to Loki. Much like his father, he was discriminated against for being different (Izuku for having a weak Quirk, Loki for being a Frost Giant), and as his flashback reveals, he and Inko met similarly to Izuku and Ochako: He tripped on his feet and she stopped him from falling with her Quirk.
• Giving Up on Logic: Even after learning about aliens and magic, Eraserhead still manages to keep his cool and navigate through these new discoveries... at least until he meets Cosmo, the Guardians' telepathic Russian dog. Then he just gives up and begs for a drink.
• Godzilla Threshold:
  • Izuku sics both All Might and his newly controlled Nomu against the Kursed Dark Elf during the USJ.
  • During the Final Exams, Izuku takes advantage of the fact that the rules do not forbid outside help and asks Thor to take on All Might.
  • Nezu, for his turn also takes advantage of this loophole and calls in Hawks to take on the students.
  • Ultron represents such a threat to humanity, that as soon as the United Nations finds out about his return, they order I-Island and any survivors left on it to be destroyed via an air strike.
• Greater-Scope Villain: Thanos, who is leading the Big Bad Ensemble of the story and seeks the Infinity Stones for his own agenda.
• Guns vs. Swords: A variation of this argument happens between Kraven and Taskmaster during the League's training session in chapter 66.
  Kraven: There is no satisfaction in guns. They leave no time to savor your victory or for your prey to wallow in defeat. Which is why I will always prefer my bare hands.
  Taskmaster: How antiquated of you. But last I checked, guns get the job done far better than your hands.
  Kraven: Maybe that is because you lack imagination.
  Taskmaster: I'd prefer that than lacking common sense-
• Heroes Gone Fishing: To take a break from every major and tiresome arc, some chapters are dedicated solely to the heroes to relax and get rest.
  • Chapter 17 is mostly about the newly formed Mischief Squad enjoying themselves after the USJ and preparing for the Sports Festival.
  • Chapter 43 is centered around Izuku and Ochako's date in Asgard and their eventual Relationship Upgrade.
  • Chapter 50 is Mischief Squad hanging out in the mall and preparing themselves for their trip to I-Island.
  • Chapter 53 features the hero students enjoying I-Island, right before the arc takes a very dark direction.
• Hidden Agenda Villain: Loki is definitely one. First, he arranges for Eri to escape Overhaul's clutches, then he invades an American military facility and kills all its staff, not to mention his alliance with All for One and Thanos. Whatever is this object, he claims is to make a better world for Izuku and Inko.
• Honorary True Companion:
  • Mina and Toru are this for Mischief Squad. Tenya is this for Momo's faction of the "Prank War".
  • Kitty is one of the Guardians, an exchange student between the team and the X-Men.
• Honorary Uncle: Logan and Wade Wilson are this to Izuku.
• Hypocritical Heartwarming: As far as Katsuki is concerned, no one gets to beat up Deku except him.
• Imposter Forgot One Detail: Izuku nearly succeeds in fooling the Kurse Dark Elf at the USJ by shapeshifting into Malekith, except for one detail: The scar on half of his face that Malekith got from Thor in their last encounter.
• The Infiltration: The Skrulls have successfully infiltrated the HSPC and if Loki's comments are of any indication, there is also infiltrators inside of U.A.
• In Love with Your Carnage: When Tenko mentions how he intends to brutalize any CRC (a hate group that targets mutants), Tsu leaves an... excited "ribbit" in the group chat. Tenko is left embarrassed by this.
• In Spite of a Nail: All for One still takes a grandchild of Nana as his apprentice even though Tenko is saved. He just got Hana instead.
• Innocently Insensitive: Zigzagged. Izuku was deliberately trying to rile the League up during his opening speech at the Sports Festival. However, he had no idea that by saying that Hirona, who had to endure a lifetime of abuse at the hands of All for One, doesn't matter makes him sound like an apathetic jerk making fun of Hirona's trauma, which only makes her hatred for him grow further.
• I Will Only Slow You Down: Played for Laughs. Tsu makes it very clear she will kick Tenko's ass if he injures himself training or at patrol. After being injured by Stain and saved by his friends, Izuku points out that Tenko's SOS went on their group chat, which means Tsu definitely saw it. Tenko tells Izuku to leave him behind.
• I Work Alone: Deconstructed. Loki's training with Izuku taught him to not trust nor rely on others so he could always have control of his surroundings. This mentality falls apart pretty fast, mainly during the Sports Festival, when Izuku is ambushed by the 1-B mob and nearly injured before his teammates show up to save him. Ochako's positive influence also helps him realize that is okay to ask for help when you need it.
• I Read It for the Articles: Thor casually mentions that Loki told him about the Wild Wild Pussycats magazine that Izuku keeps in his room for articles. Denki makes fun of him for it, until Thor mentions that he knows the young boy has a Mt. Lady magazine (Christmas edition with a holiday spread) in his room, embarrassing him as well.
• Jack Bauer Interrogation Technique: Played for Laughs example. After Izuku makes Aizawa's sleeping bag disappear during one of his pranks, Eraserhead decides to get the truth out of him by hanging Izuku from the school rooftop.
• Jerkass Realization:
  • Inko makes sure Izuku understands how mean his and Loki's pranks could be when she points out that their victims were scared and could have gotten hurt.
  • Izuku calling him out forces Nighteye to realize he did not take into account Mirio's opinion on whether he wants to be All Might's successor or not.
  • Bakugo has one during the Sports Festival. Seeing Monoma copying his Quirk and using it to hurt Izuku causes him to snap and beat the hell out of the copycat, while at the same calling himself out on his attitude.
  • Shinso has one during his time hanging out with Mischief Squad. Having spent his entire life being mistreated because of his Quirk, as well as being related to a villain, he already expects the worst out of people before even meeting them properly, which is exactly what others did to him.
• Jerkass to One: Inko may be an all-around sweetheart, but she really can't stand Deadpool. Given how much of a bad influence he can be on her son, is totally justified.

K-R

• Kill the God: Gorr rampages through Omnipotence City and slays as many deities as he can.
• Kindhearted Cat Lover: Both Mina and Kitty are examples of it. Mina, as a true Alien fangirl, has a cat named Jonesy.
• Knew It All Along: Nejire knew that the disguised girl at the DVD shop was Hirona all along. She just pretended not to so they could have a conversation.
• Knight of Cerebus: In true Marvel fashion, Ultron. From the moment the villainous A.I. is mentioned back in chapter 48, all lightheartedness of the story gradually falls down until it disappears completely during the I-Island arc. To immediately establish himself as a threat like no other in the story presented so far, he brainwashes Wolfram and kills Sam and all the Brotherhood mercenaries at the Expo in the most brutal and bloody way possible before setting off to enact a genocidal scheme to destroy humanity. By the end of the arc, not only is he the first major villain (besides Loki), to effectively defeat the Heroes, but he is still loose in the world, thanks to Loki's arrival.
• Know When to Fold 'Em:
  • A huge sign of Bakugo's Character Development is shown when instead of fighting the Black Berserker attacking the hospital, he grabs Hitomi and blasts away from the fight.
  • How the students win the match against Ghost Rider during the Final Exams. Being the strongest opponent left with All Might defeated, Momo and Izuku slowly make their way to the ruined gate and pass through it instead of fighting him.
• A Lady on Each Arm: An accidental and Downplayed example, but while listening to music together during their break, Shoto finds himself with Kyoka on his right side and Momo on his left.
• Laser-Guided Karma: Vlad King telling his students that Izuku is a villain and having them target him directly results in Nedzu firing him.
• Leaning on the Fourth Wall:
  • In Chapter 37, during Mischief Squad's talk during their chat, Tenko jokes that Izuku has taken so long to answer his text, that it feels like a week. The story is released on a weekly, or often bi-weekly schedule.
  • KageNekem mentions that during the League's trip to Knowhere, Himiko was supposed to joke about how it feels like they have been traveling for over a month, but forgot to add it. There was a 6-week break between Chapters 66 and 67.
• Let's Get Dangerous!: During his match against Mei during the Sports Festival, Tenko grabs a pair of electrified wires to decay them. It works. And gains both him and All Might a lecture from Recovery Girl about its recklessness.
• Literal Split Personality: Whenever Izuku loses control of his emotions, his Decoys, each one representing an aspect of his personality, manifest. So far the revealed personas are: Two, Confidence; Three, Logic; Four, the Prankster; Five, Guilt; Six, Hunger, which could also mean hunger for power; Eight, Anxiety; Nine, Depression; Ten, Anger; Eleven, Self-Sacrifice; Twelve, the Analyst; and Thirteen, Love, more specifically his love for Ochako.
• Loophole Abuse:
  • During the Quirk Assessment Test, Izuku finds a lot of loopholes to use. During the Ball Throw, Aizawa says he must stay in the circle. So Izuku enlarges the circle to include Ochako so she to throw the ball for him.
  • During the Heroes vs Villains exercise, All Might says the participants can use any resource they want. The only rules are they cannot do excessive harm. So Izuku has a projection in the monitor room so he can see where everyone is during his round.
• Master of Illusion:
  • Izuku, having inherited his father's powers, has learned to use illusions and trickery to help people and fight villains. By incorporating the Reality Stone scepter, he can make any of his illusions physical.
  • Mustard, whose Quirk not only causes people to have hallucinations but also like Mysterio, uses holographic drones to make his illusions realistic.
• Meaningful Name:
  • Denki realizes his name meaning "Thunder" is rather on the nose for his electricity powers and deduces it was on purpose on his father's part. This prompts him to pick "Raikou" the Japanese god of thunder as his hero name. Although it kinda backfires that is also the name of a Pokemon.
  • Overlaps with Punny Name on Izuku's case, since the "Midori" from "Midoriya" means "green", and that's his father's favorite color.
  • Hirona's name means "Help from God", which fits since Loki was the one to resurrect her.
  • To fit Mephisto's bad sense of humor, his alias as a doctor at Hosu Hospital is Akama Reiwaru. "Akama" has kanji for "Red, devil", while "Reiwaru" means "Spirit, evil".
• Merged Reality: The story's setting ultimately turns out to be this. Back during the Secret Wars event nearly a century or so prior to canon, the only solution the Avengers and their allies found to save both their world and the one they were in direct collision route thanks to Beyonder's actions was to use the Infinity Stones to combine both the Marvel Universe and the My Hero Academia Universe, which led to the Dawn of Quirks and the current events.
• Mexican Standoff: One happens during the Hosu arc between Gentle, Stain, and Nagant.
• Mirror Match:
  • Tenya's duel against Kamakiri is a near match of the one between Tensei and Stain. Both fights are even juxtaposed in the same chapter.
  • Izuku's match against Denki in Chapter 27 is very similar to the sparring session between Loki and Thor at the beginning of the chapter.
• Mistaken for Gay: During Izuku's livestream with Gentle, people think he is dating Shoto or Bakugo. Shoto, always inept, thinks dating is somehow related to Izuku's alien origins, and Bakugo... says that Izuku would be lucky to date someone like him. Everyone is weirded out.
• Mistaken for Related:
  • Shoto still believes Izuku is someone's secret love child, except here it's Star and Stripe instead of All Might.
  • During the second event he often gets distracted by the thought that his classmates are related to international heroes: He thinks Hatsume is related to Iron Man, Iida to Quicksilver, and Sero to Spider-Man. He even promises to get Endeavor's credit card to buy a mobile board so he can write down his theories.
• The Mole: While Aoyama retains his role as the U.A. Traitor, it's revealed that Izuku has his own double agents inside the League: Himiko and Compress.
• Mook Horror Show: The Brotherhood mercenaries find themselves going through this during the I-Island attack, courtesy of Fumikage, the new Moon Knight.
• Multi-Part Episode:
  • Season 1 has chapters 10 and 11, titled "This Is Getting Out of Hand Part 1 and 2" covering the Battle Trials, and chapters 14 and 15, titled "Now There Are Two of Them Part 1 and 2", covering the end of the USJ arc.
  • Season 2 has chapters 36 and 37, titled "One Important Trait in Common Part 1 and 2" set halfway through the Internships arc.
  • Season 3 has the three parters "What You Started Part 1-3" going from chapters 46 to 48, covering the Final Exams arc, and chapters 56 to 58, "Cheat Code Part 1 to 3" covering the I-Island arc.
  • Season 4 originally had chapters 64 to 66, "A Talk About Your Powers Part 1 to 3" and chapters 67 to 69, titled "You Didn’t See That Coming? Part 1 to 3", covering the beginning and the middle of the Guardians Trainning Camp arc, but the titles were ultimately changed by the author because he felt they were getting to repetitive.
• The Multiverse: Loki confirms the existence of it during his conversation with Nezu regarding the story behind the Infinity Stones.
• Mythology Gag: Now with its own page.
• Nice Job Breaking It, Hero: The heroes didn't realize that the Power Stone was so... well, powerful, that it required the strength of all the other five stones to be destroyed until after the Mind, Space, and Time Stones were already destroyed, leaving them stuck with Power, Soul and Reality ones. Ultimately subverted, as it was actually part of Thanos' Batman Gambit, who hid the Stone as part of his long scheme plan to use them.
• Nice Job Fixing It, Villain:
  • Sure, Hirona. Brag about how you are the only person capable of controlling your ultra-powerful bio-weapon in front of a shapeshifter, that's not going to come back and ruin you.
  • A villain-to-villain example. In order to stop Nighteye from getting too close to Thor and by extension himself, Loki arranges the creation of a villain (Absorbing Man) and sends him on a planetary rampage, forcing Thor to leave Earth to stop him. Unfortunately, this happens at the very same time when Gorr arrives to enact his Roaring Rampage of Revenge leaving Earth defenseless against the God Butcher and nearly getting Izuku killed in the process.
• No Good Deed Goes Unpunished: Despite saving Izuku and Denki's lives by teleporting them off I-Island as it was being destroyed, Heimdall is stripped of his position of the watcher for breaking Odin's Law.
• No-Holds-Barred Beatdown: Bakugo and Izuku's match during the Sports Festival evolves into this, to the point that Izuku forgoes using his illusions and goes straight into beating each other up since he promised to give Bakugo a fair fight, no tricks or gimmicks.
• Noodle Incident:
  • Izuku once hid under the bed of a guy who insulted Hawks to prank him.
  • Thor forgetting Mjölnir on the toilet back at his family's home is an often occurrence, much to Denki's annoyance when he needs to use it.
  • At some point in the past, Izuku and Deadpool stole the X-Jet to go to a taco place on the West Coast of the United States that was closing soon, and needed to get there fast. Thankfully, the jet was pulled back to the mansion before they could go further.
  • Logan mentions that his healing factor is the only reason he is not dead because Thor is such a Bad Liar, he nearly got both of them killed in a previous incident.
  • Whatever Nezu did to Izuku for messing up with his tea was so bad that Izuku had to sign an NDA.
• Not Hyperbole: As it turns out, the "actor playing Santa" that visited U.A. during the prologue arc was Santa Claus himself. Aizawa is not even shocked, just disappointed for not realizing it sooner.
• Offing the Offspring: Nighteye has a vision of a possible future where Loki seemingly kills Izuku when the boy refuses to join him in his plans. It could be an alternate timeline, or the Izuku that died in his vision is actually one of his clones.
• Oh, Crap, There Are Fanfics of Us!: Apparently, Deadpool writes explicit slash fanfics pairing Endeavor with All Might and other Pro Heroes. He releases several of them in Chapter 59 to troll the Flame Hero, and if his warning means something, he has several more on the way.
• One-Steve Limit: There's Thirteen, the Space Hero, and Thirteen, Izuku's Literal Split Personality that embodies his love for Ochako. The narration specifically refers to them as "Hero Thirteen" and "Decoy Thirteen" even when they are not in the same scene. Although during their fight at the Final Exams, the author purposely kept it vague just to mess with the readers. He said the winner was Thirteen.
• Out-Gambitted: Nezu pulls Izuku through it twice during the Final Exams. First by switching the teachers originally assigned to each student, then by calling Hawks when it seems like the students have taken care of the teachers.
• Outside-Context Problem: As a common example, there are not enough people or heroes aware of aliens and the supernatural, and they are not prepared to handle threats as such. As for individual examples:
  • The Dark Elves are believed to have gone extinct after their major fight against Asagard, so is a shock to Izuku to see one of them amongst the villains attacking the USJ. In truth, they have actually joined Thanos and their existence has been concealed by Loki.
  • Gorr. No one expected the God Butcher to still be alive centuries after his last appearance, so his galaxy-wide Roaring Rampage of Revenge catches everyone off guard. Even Loki, one of the biggest masterminds in the story admits he did not Gorr's sudden appearance throws a wrench in his carefully planned schemes.
  • Mephisto. While his grudge against Loki is nothing new, nobody expected him to hand Tenya the Ebony Blade and make Tensei Ghost Rider's host, causing even more problems to the villain's side and forcing them to step their games.
  • Two heroic and literal examples happen during the Final Exams. Exploring the Loophole Abuse of Nezu's phrasing about the rules for the exam, Izuku arranges for Thor to join the students and take on All Might. On a rather ironic twist, Nezu also makes use of said loophole and brings Hawks to face the students after they seemingly defeat the teachers.
  • New League members, Kraven and Taskmaster, who show up out of nowhere, catch Shishido off guard and kill him.
  • Another heroic example happens during the I-Island arc. Since Tenko never displayed Decay during his time on the island, Ultron is unable to create a countermeasure against it, allowing the boy to be a decisive point for the heroes (temporary) victory against the android.
• Pint-Sized Powerhouse:
  • Eri. With Izuku's training, the little girl becomes a legitimate badass, best shown when she trashes the Bakugo clone in front of the real one, as a way to warn him to not mess up with Izuku.
  • Laura counts as one as well, being a 12-year-old Wolverine clone.
• Playful Hacker: Mei, unbelievably so. She manages to single-handedly hack her way into I-Island security and not only invades get herself free access to the island and all of its locations, but she also takes control of all the decommissioned Iron Man suits at the Stark exposition.
• Point of Divergence:
  • Loki finds Hana in the ruins of her home after Tenko's Quirk awakened, and is the one who delivered her to All for One, which results in her taking Tenko's role in canon.
  • All Might and Gran Torino find Tenko in the aftermath of his Quirk Awakening and family's death, preventing him from walking the path of villainy.
  • Vlad King being fired from UA meant a new teacher for 1-B is needed, and it leads to Wolverine being their replacement homeroom teacher.
  • Since Gorr was the one to attack Hosu with his Black Berserkers, the Nomus originally used on the attack are still alive.
• Power Misidentification: Izuku's power is officially listed as a Quirk that creates illusions, but that is a deception to hide the fact he can do much more than that, and the fact that it is not, in fact, a Quirk at all.
• Pretender Diss: Izuku delivers one to Mustard when the young villain accuses him of not using his powers to their full potential.
  Izuku: No. You've been using those methods to cause only pain. But illusions are so much more. They can let you see a world you've never seen before, bring ideas to life, keep you company on lonely nights, let a little girl know that the world isn't as bleak as she thinks. The point is, you're barely scratching the surface of what illusions can do.
• Rage Breaking Point: Invoked by Bakugo and Decoy Ten (Anger), towards Izuku. Since Izuku has been surpassing his negative feelings since the events of I-Island and this has been taking a toll on him (even if he refuses to admit it to anyone, especially himself), Bakugo takes matters into his own hands and forces Izuku to admit the anger he had been feeling for a long time:
  Izuku: Fine!! Yeah, Kacchan, I am mad. I'm mad because I couldn't do more to protect everyone on I-Island. Or Hosu! Or the USJ! [...] I'm mad that my powers aren't coming as easy to me as they did with my dad! I'm mad that despite everything I'm trying, Shigaraki and the League are still out there! I'm mad that sometimes, my friends can't see how amazing they are to me! And I'm even madder that I had my scepter taken away, which was my best chance to protect them! And! I'm mad at myself for even feeling this way! And I'm mad at you for dragging me out here!
• Related in the Adaptation: Izuku and Denki are cousins through their fathers Loki and Thor.
• Refusal of the Call: Mirio rejects One for All on the grounds that Permeation is an esoteric Quirk and having to master One for All on top of his original Quirk will interfere with him trying to save people.
• Roaring Rampage of Revenge: Gorr goes through one like in Love And Thunder, slaughtering gods from Omnipotence City to Midgard in his insane crusade.
• Rules Lawyer: Izuku will take advantage of any loophole he can to come out on top.
• Running Gag:
  • All Might looking at his "Teaching Guide for Dummies" for any kind of answer, whether is at school, regarding One for All, or about aliens and the supernatural.
  • Endeavor yelling Shoto's name during the Internships arc. It gets to the point it also acts as an Answer Cut during the students' discussion about their Internships. By the time of the Hosu attack, however, it gets Running Gagged.

S-Z

• Season Finale:
  • Chapter 17 acts as this for Season 1, wrapping the events of the Prologue until the aftermath of the USJ arc.
  • Chapter 42 is this for Season 2, which goes from the setup for the Sports Festival until the end of the Internships arc.
  • Chapter 62 is one for Season 3, which covers the events of the Final Exams until the aftermath of the I-Island arc.
• Serious Business:
  • Izuku takes his pranks very seriously, taking a surprising amount of time carefully planning each one, which is why he makes Momo his Sitcom Arch-Nemesis every time she stops his plans.
  • Hirona does not accept when someone questions her knowledge of movies. So much so that when she gets into an argument with Mustard over the Rosebud ending from Citizen Kane, instead of pulling the movie from her laptop, she goes to the mall's video store to get a physical copy of it just so there is no doubt of its authenticity.
• Shadow Archetype:
  • Loki is one to Izuku. Both grew up being ostracized by their peers over being different, are genius planners and masterminds that make up for not being exceptionally strong and dream to make a better world, but while Izuku always held his hopes to achieve his dream no matter what and had people (even if not so until he met his friends), Loki grew bitter, spiteful and manipulative, believing that any means justify the end he seeks.
  • Dictator is one to Hitoshi. Both have Quirks that allow them to control people (Hitoshi has Compelling Voice, Dictator has People Puppets) and grew up being mistreated over their "Villainous Quirks", but as Hitoshi points out, Dictator gave up and just proved what the others said to right by embracing villainy, while Hitoshi continued fighting no matter how hard the path mad itself to him.
• Shared Family Quirks:
  • Much like Tenko loves to frame everything in gaming metaphors, Hana likes to use movie metaphors while explaining her plans. She is also prone to use her Quirks to throw tantrums and break everything on Kurogiri's bar whenever a movie or TV character does something stupid, like separating an established couple.
  • Denki is as much of a Bad Liar as his father and Izuku.
• Ship Tease:
  • Between Izuku and Ochako, as well as Denki and Setsuna. Tsuyu and Tenko get some as well before the Internships.
  • A three-way starts between Shoto, Momo, and Kyoka during the Guardians Training Camp arc, with the trio starting to enjoy each other's company more and more during it.
  • Yui starts to notice one happening between Fumikage and Reiko during the Guardians Training Camp arc.
• Shipper on Deck:
  • Eri, Mina, Toru, and Decoy Thirteen are this to Izuku and Ochako, as well as to Denki and Setsuna and Tenko and Tsu.
  • Nagant seems to be this for Nejire and Hirona, smugly noticing how the young villain made a lot of research about the hero following their encounter.
  • Mina is one for Momo and Kyoka, while Toru is one for Momo and Shoto. Thirteen, however, is implied to ship Momo, Kyoka ''and'' Shoto.
• Shout-Out: Several to several franchises.
  • Star Wars:
    • While getting curb-stomped during their training at the beach, Izuku comments how much he hates sand.
    • After Decoy Three discloses how little the chances of successfully stealing Stormbreaker from Asgard's vault, Izuku tells him to never tell him the odds.
    • Izuku and Ochako excitedly talk about Thirteen's "Rylith Rescue". Ryloth is the homeworld of the Twi'lek.
    • This exchange.
      Izuku: And…what if I don't? Are you gonna stop [his pranks]?
      Momo: I will do what I must.
      Izuku: You will try.
    • Prior to this one, in the flashback while Drunk with Power from using his scepter, Izuku comments that with its power, he could bring peace, freedom, justice, and security to all, the same line used by Anakin to justify his actions to Obi-Wan before their showdown in Mustafar.
    • The two-part Chapters 10 and 11 are titled "This Is Getting Out of Hand" while Chapters 13 and 14 are titled "Now There Are Two of Them". The phrase is spoken by Viceroy Gunrey in The Phantom Menace.
    • Snipe's Online Alias in the teachers group chat is Mandalorian.
    • After the Sports Festival, Shoto decides to spend some of Endeavor's credit card in a super expensive restaurant called Bistro de Lothal. Lothal is the homeworld of Rebels protagonist Ezra Bridger.
    • Izuku mentions ordering pizza from Ferrix Pizza. Ferrix is a world located in the Free Trade sector of the galaxy's Outer Rim Territories.
  • Phineas and Ferb:
    • Nedzu briefly mentions that he runs the Japanese branch of OWCA. There's then an immediate scene cut where Koda's pet bunny disappears for a mission and Koda paraphrases Phineas when he asks "Where's Yuwai?"
    • While losing themselves before the I-Expo gala, Denki mentions that there is a pavilion from Drusselstein close to the Egyptian exposition.
    • The jellybeam jar scene from Chapter 63 is just like the one shown, except Denki breaks the jar instead of eating the beams.
  • Yu-Gi-Oh!:
    • During his duel with Strange in Joutunheim, Izuku creates a Blue-Eyes White Dragon
  • Yu-Gi-Oh! The Abridged Series:
    • Chapter 44 is titled: "Because Shut Up". And the title is dropped by Tenko during his talk with Tensei.
    • This exchange:
      Setsuna: C'mon homie, don't be a player hater.
      Hitoshi: I'm not a player hater, I just hate you.
  • This other exchange, by Dabi, during his Villains Out Shopping moment in Chapter 60.
    Dabi: Since I'm having a good day, I'll let you choose, lady. Would you rather be burned alive or strangled to death?
    Attendant: B-but you said no bloodshed-
    Dabi: I promise that neither will make you bleed.
    Attendant: F-fuck you!!
    Dabi: Burned alive it is!
• Sitcom Arch-Nemesis: Played with, in that, it's made abundantly clear that, outside of the subject of Izuku's pranks, they are all rather close and friends with one another.
  • Izuku is this to Aizawa and Momo, who are left with the undesirable task of dealing with the Prince of Mischief and his pranks. Both hate the job.
  • In return, Momo is this to Izuku, since she is always seeing through his schemes and pranks and is the main opposition to it. Word of God describes their relationship as below:
    Momo: You can't prank.
    Izuku: And I took that personally.
  • Eventually, this "conflict" evolves to include Izuku and all members of Mischief Squad (plus honorary members like Mei, Mina, and Toru), against Momo and the rest of 1-A. Once they officially declare a formal war in Chapter 60, Izuku and Momo end up trading Tenya and Hanta to each other's sides, Tenya is initially against the idea until Tsu reveals to him that Izuku was responsible for the scorpion prank.
    Tenya: Midoriya. You will be happy to know I still consider you one of my closest friends. I know this conflict isn't made to be taken personally. However, in light of recent discoveries, know that I will give my full effort and participation to Yaoyorozu and her attempts to stop you. I will be returning the favor for the scorpion incident.
    Denki: Oooooh. That's the politest way I've ever heard someone say 'it's on, bitch!'
• Snark-to-Snark Combat: Tenko and Gran Torino are prone to such:
  Gran Torino: Tenko! Where are you?! This breakfast isn't gonna make itself!
  Tenko: Make it yourself, you old geezer!
  Gran Torino: I would, but I'm just so old! I could whither away at any moment!
  Tenko: The bruise on my back from our last spar disagrees!
  Gran Torino: Maybe if you'd get off your phone every once and a while...
  Tenko: Say that to my face! Oh wait, you can't! You're not even a meter tall!
  Gran Torino: I'm 1.2 meters tall you shit! And another thing!…"
• Sketchy Successor: As part of his Kick the Dog routine with Hirona, All for One loves to frame her as inferior to Tenko/Tomura.
• Socially Awkward Hero:
  • Izuku and Shoto to an even greater extent than canon.
  • Tenko never interacted with anyone besides Gran Torino, or the online gamers he plays with, not to mention his Dark and Troubled Past, so it takes a while before he can fit in with his classmates.
  • Hirona is a Socially Awkward Villain. Being raised by All for One, with zero interaction with anyone besides him and Kurogiri, the poor girl is as socially inept as any of the hero students mentioned above. Interacting with Nagant and the rest of the League helps the young villain get out of her shell.
• Sparse List of Rules: According to Izuku, Santa Claus has a very specific set of rules about what kind of gifts he can bring: No living beings, no weapons of any kind, making people love for each other (that's Cupid's job), or bestowing luck or good fortune to business. And since Izuku and Loki are on the naughty list, they have a special addendum where they are forbidden to ask for iconic items like Excalibur or Cap's Shield.
• Story Arc:
  • Chapters 1-6: Pre-UA
  • Chapters 7-11: Introduction to a Trickster
  • Chapters 12-17: USJ and Aftermath
  • Chapters 18-21: Worldbuilding and Sports Festival Prep
  • Chapters 22-29: Sports Festival and Aftermath
  • Chapters 30-35: Heating up for Hosu

  • Chapters 51-58: I-Island Trip and Attack
  • Chapters 59-62: Aftermath of I-Island.
  • Chapters 63-?: Guardians Training Camp
• Sympathy for the Devil: While Izuku acknowledges that Gorr's actions are monstrous and unforgivable, he can't help but sympathize with the villain's tragedy, going as far as to apologize to him for what happened to his family.
• Talking to Themself: Literally, in this case. Izuku has a number of illusion decoys that embody different aspects of his personality and he is often found speaking with them.
• Take That!:
  • During their confrontation at the USJ, Hirona asks Tenko if he saw the newest American hero movie. She says it was good, but it had too many jokes and the villain was completely wasted. These just happen to be the author's opinion about Thor: Love and Thunder.
  • Taskmaster throws a jab at Black Widow (2021) by saying that Antonia Dreykov is a disgrace to the name Taskmaster and should not be spoken of.
• Title Drop: All chapters are named after a sentence said by a character during it.
• Took a Level in Badass: The Class 1-A students who did not gain power-ups managed to keep up with the ones who did by the time of the Final Exams. Momo is the best example of it, standing up against Izuku.
• Took a Level in Kindness:
  • It's subtle, but after the Sports Festival, Bakugo starts to go through it. First taking therapy sessions to manage his anger, then chooses to rescue the civilians rather than fight the monsters during the attack on Hosu, and finally cooperates with his classmates during the Finals.
  • The events on Hosu give Monoma and the 1-B students who attacked Izuku a wake-up call, prompting them to apologize to Izuku. Monoma says he will apologize as well when he makes peace with his mistake.
• Trojan Horse: How the League manages to infiltrate Knowhere. They hijack a scouter ship, torture the access codes out of the pilots, and bypass security.
• Two-Person Love Triangle: Colossus is unaware that his girlfriend Nemuri Kayama is actually his co-worker Midnight, and the R-Rated Hero takes a lot of amusement in teasing him with her persona at work. Ultimately subverted since both of them are simply trolling their co-workers.
• The Trickster: Izuku, having learned from his father, has decided that doing what is right is more important than obeying the rules.
• Unconventional Learning Experience: In-Universe example. Tenko's love for video games eventually helps him figure out how to properly activate and use One for All. As he points out:
  Tenko: In other words, you activate it once and it increases all your stats passively without having to worry about activating it again. Instead of treating One for All like an active skill and turning it on every time I wanna use it with a delay…could I treat it like this elixir? Turn it on once and use it to increase all of my stats at the same time?"
• Villain Episode:
  • Chapter 34 explores Hirona's origins, as well as how Gorr and Stain started to work together.
  • Chapter 49 is set during the first full meeting between the new members of the League.
• Villain Has a Point: Stain points out the dichotomy in Gorr's plan to kill Odin from one villain to another. If the gods, including Odin, are as uncaring as he claims, he would not be moved to save the grandchildren that Gorr plans to target. Gorr reacts with silence before claiming it does not matter.
• Villain Team-Up:
  • There is a major villain alliance happening between Loki, All for One, Thanos, and the Skruls.
  • Stain and Gorr team up to get rid of all gods and false heroes in the universe.
• Villains Act, Heroes React: Hirona exploits this during the Sports Festival. Since most of the heroes are either guarding U.A. or watching it from home, she decides to make her move and prove the League is a threat to watch out for by saving and recruiting Lady Nagant to their group.
• Villainous Friendship:
  • Downplayed with Gorr and Stain. Stain regards Gorr as a partner in his crusade to purge the world of false heroes, but is disturbed by his sadistic and psychotic behavior.
  • The League seems far closer to each than they were before the Kamino arc, thanks to Hirona not being as much of a manchild overdependent on All for One as Tomura was in early canon. Special mention goes to Dabi and Daken, who both want to kill their hero fathers.
  • Wolfram and Dictator, to the point Wolfram even goes back to save his friend after Ultron is seemingly defeated so they can pick from where they left off and rebuild the Brotherhood of Mutants.
• Vile Villain, Saccharine Show: The story may be a little upsetting at some points, but it is primarily a comedy with plenty of Slice of Life sprinkled through it, with main villains like Hirona and Loki receiving room to show their Hidden Depths. Other villains, however, really make the story take a dark turn.
  • Gorr is the first genuine threat faced by the students, his galactic rampage leaving bodies behind, his wicked sense of humor, and his willingness to destroy anyone for the sake of his revenge make him a perfect example of it. He brutally murders Yoroi Musha during the Internships arc and laughs at it.
  • Kraven the Hunter and Taskmaster. These guys may work for the League of Villains here, but they clearly outclass all of them, Lady Nagant being the exception, and they are a serious danger to anyone unfortunate enough to cross them. Shishido ended on the short end of the stick during chapter 49, being quickly defeated by Kraven before being executed by Taskmaster.
  • Ultron. From the moment he is mentioned by David Shield, all levity from the story vanishes, or at the very least is diminished. Then he debuts during the I-Island arc, and everything about him is seriously Played for Horror.
• Voluntary Shapeshifting: Izuku can shapeshift into animal form, although it takes time and practice to learn a new form.
• Welcomed to the Masquerade: By the end of chapter 59, all Class 1-A students (minus Mischief Squad members) plus Mei and Melissa find out that Izuku is a demigod.
• "Well Done, Son" Guy:
  • Izuku is this to a fault, for as much as he loves being a hero, his worship for his father is something he craves the most. Unfortunately, this is also a major Fatal Flaw that Loki exploits to manipulate his son for his schemes.
  • Hirona is an example of it, desperately attempting to gain All for One's respect and show how much better than Tenko she is. It isn't until Nagant shows up and acts as Parental Substitute that she stops trying to impress the mastermind.
• Wham Episode:
  • Chapter 29 - Anyone: The Skrulls are revealed to be part of the Villain Team-Up between Loki, Thanos, and All for One, and if that wasn't bad enough, they have already infiltrated several levels of society, mainly the HPSC. And is revealed that Vlad King did not go through a case of Adaptational Jerkass, but was rather a mole inside U.A., and despite being out of the school, there are at least a couple more infiltrators inside U.A.
  • Chapter 39 - And He Shall Appear: We find out who is the man who showed in the last chapter cliffhanger: Tensei Iida. Flashbacks to earlier explain what actually happened: Doctor Reiwaru is revealed to be none other than Mephisto, the Devil from the Marvel Universe. He also reveals he was the one to give Tenya the Ebony Blade, just to get revenge on Loki by targeting his son's friends. He promises Tensei to give his legs back and the power to save Tenya from Gorr in exchange for his soul, which Tensei agrees, becoming the new Ghost Rider.
  • Chapter 42 - Smooth Sailing from Here on Out: Tensei becomes a member of U.A. staff in order to learn how to better use his Ghost Rider powers, and Nezu fabricates an entire fake story to cover it up. And while Stain's Motive Rant still brings the same familiar faces to the League (plus Mustard, who seems to be taking inspiration from Mysterio for his costume), it appears they will be joined by outside villains as well: Taskmaster, Daken, and Kraven the Hunter.
  • Chapter 48 - What You Started, Part 3: Wolfram is revealed to be in charge of the Brotherhood of Mutants, as well as in possession of Magneto's helmet. Meanwhile, it turns out I-Island has several items from the Marvel Universe located on the tower vault, including a pair of symbiotes (black and red, specifically), Doc Ock, Rhino, Whiplash, Vulture and Green Goblin's suits, Juggernaut's helmet, a vial of super soldier serum, another one of Goblin formula, and a radioactive spider. And the biggest reveal of it all: David ditched the idea of the Power Amplifier... in favor of an idea a million times worse: The Ultron Program.
  • Chapter 51 - Queen in Black: The black symbiote manages to break from inside the vault below the tower and latches itself on Setsuna, turning her into Venom's new host.
  • Chapter 54 - Tomorrow: Wolfram and the Brotherhood begin their attack on I-Island. After they killed the head of the I-Island Board of Directors, David activates Ultron. The android quickly turns the table against all of the involved parties, lobotomizing Wolfram, as well as killing Sam and all the Brotherhood mercenaries left. He then captures Izuku, All Might, David, and Vision before broadcasting a message throughout the island stating that Doomsday has arrived for them.
  • Chapter 56 - Cheat Code, Part 1: It's revealed how Fumikage survived his mortal wounds after the following chapter: The boy was chosen by Konshu to become the new Moon Knight and immediately returns to fight by taking down the remaining Brotherhood members left on the I-Island. And Ultron implies he is somehow related to Izuku, raising the implication that Loki is somehow connected to the android's return.
  • Chapter 58 - Cheat Code, Part 3: Also known as the first Game Changer chapter of the story so far. With Tenko's help, all the remaining physical copies of Ultron are destroyed. Victory, however, is short-lived, as it turns out that while the heroes were destroying his bodies, the android successfully uploaded his consciousness into the I-Island servers, taking complete control of it and destroying the evacuation ship that was supposed to take the students back to the mainland. And if things weren't bad enough, the United Nations plane that is in route to the island is not going there to save the survivors, but to destroy I-Island, since Ultron's return makes him too much of a threat to be allowed to live, even if it costs the lives of All Might, Vision and the hero students. Loki arrives at the island as the destruction begins, and confirms that he was, indeed, responsible for Ultron's return, through David Shield. Or rather, the Skrull pretending to be David Shield. The God of Mischief strikes a deal with Ultron, offering him access to Adamantium and Sentinel Project in order to improve himself in exchange for help to achieve his agenda. Just as the island is about to be wiped out, Izuku decides to pull his trump card and calls Heimdall for help. The watcher, even knowing that his actions can be regarded as treason, heeds the call and uses the Bifrost to teleport Izuku and his friends back to Japan, exposing his true nature as an alien to them, before the painful realization of their defeat sinks in.
• Wham Line
  • David drops a massive one by the end of Chapter 48, which serves for the sole purpose of instilling fear in the readers' hearts after revealing he dropped the idea for the Quirk Amplifier.
    David: It's the dawn of a new age, my friend! So, tell me, what do you know of the Ultron program?
  • Chapter 54 has one that marks the turn of the arc From Bad to Worse.
    Wolfram: This is exactly what I was talking about! Ultron, a peace-keeping android, would've been kept under the control of I-Island! And do you believe they want what's best for humanity? No! But I return him to the masses, and together, we will finally have equality and peace! Under my power!-
    Ultron: Do you feel in control?
  • A shocking one is dropped by Loki in Chapter 58 during his talk with Ultron
    Loki: I agree. Which is why I didn't. You questioned why it would be difficult to bury [David's] planet? Why, because Earth is not his planet.
    (Ultron turns around and sees a Skrull in David's position.)
  • Izuku delivers one by the end of Chapter 59.
    Izuku: I'm a demigod.
  • Another one happens in the end of Chapter 69, revealing Izuku made some unexpected allies.
    Izuku: You guys shouldn’t have come here, I could’ve handled it.
    Mr. Compress: If there is one thing we have always been consistent at, it’s our ability to not listen to you, Midoriya. And for good reason.
  • Another one happens in Chapter 70:
    Tsukauchi: I don’t understand? The League has a traitor who’s willing to give them all up. All for One’s operation could be next. Isn’t this why you had me take the detective’s place a couple of months ago? So we could snuff this kind of stuff out?
• Wham Shot:
  • One happens halfway through Chapter 13, revealing who exactly Hirona Shigaraki resembles as well as her true identity.
    It's a girl. She couldn't have been more than a couple of years older than him. She wears a blue-green textured bodysuit that covers her arms and legs with yellow boots over her feet, and a red belt hangs loosely on her hips.
    Black hair went down her back with two shoulder-length strands that frame her face and short bangs that cover part of her forehead and part of the thick black domino mask over her eyes.
    And finally, a white cape flaps in the wind behind her.
  • Another one happens in Chapter 14. After being surrounded by villains at the Downpour Zone, Izuku is saved when an object resembling Mjölnir knocks the thugs and then flies right back into Denki's hand, revealing his Asgardian ancestry.
  • In Chapter 25, Shoto attempts to freeze Izuku in an iceberg... only for Izuku to reveal he has managed to control his Cryokinesis and successfully sends the iceberg to his adversary.
  • In Chapter 29, it's revealed that Loki also has the HPSC under his control, when he confronts the Commission President and arranges for her to send as many Internship offers to Izuku and his friends, only for it to be flipped over when both the President and Vlad King reveal themselves to be Skrulls.
  • Chapter 38 ended with the dramatic entrance of an unknown individual arriving just in time to save the students from Gorr and Stain. Chapter 39 reveals who is this figure: A fully healed Tensei Iida. Which is then followed by an even bigger shot when the older Iida becomes the Ghost Rider.
  • During the Final Exams, Chapter 46 ends with one of Hawks' feathers nearly hitting Izuku, revealing that the Winged Hero will be the students' adversary for the rest of the arc.
  • Chapter 58: During his talk with Ultron, Loki reveals that he will have to destroy David's world because Earth is not his planet. Which then cuts to a shot revealing David also was replaced by a Skrull.
  • After defeating Mustard, two figures approach Izuku to help him get up, which confuses the villain because both his and Izuku's illusions dissipated when they knocked each other out, and said figures turn out to be Himiko and Compress, who seem to be in very friendly terms with the trickster.
• What the Hell Are You?: Okimoto from the Brotherhood gives one to Fumikage during the Mook Horror Show he is subjected to. His answer is the Badass Boast above.
• What the Hell, Hero?: Izuku calls Nighteye out for acting as if he knows what's best for One for All without taking into account anyone else's opinion on the matter, especially Mirio's who has every right to reject it.
• When All You Have Is a Hammer…: Denki drops this one when instead of wasting time counting the beams on the jar, he just breaks it and moves to the next objective.
• Where's the Fun in That?: Besides being name-dropped, that's actually the title of the story's first chapter.
  • First by Loki in Chapter 1:
    Maw: I am curious. We do not have much information on Terra. How do you plan to prepare mankind for our arrival? Tell me.
    Loki: Now where's the fun in that?
  • Later in Chapter 50, as part of the Call-Back.
    Izuku: Hey, Shinso. Would it help if I turned [Denki] into a cat?
    Hitoshi: …Maybe.
    Denki: Heeeeey! What if you just made an illusion of a cat?
    Izuku: I could… But where's the fun in that?
• Wizard Duel: Izuku and Doctor Strange have one inside the Mirror Dimension in Chapter 62.
• The Worf Effect:
  • Yoroi Musha is one of the Top 10 heroes of Japan, yet he is swiftly killed by Gorr during the Hosu attack.
  • In his introduction chapter, Shishido is shown easily dispatching the CRC cultists during the raid, only to be curb-stomped by Kraven and executed by Taskmaster.
  • Both the Hulkbuster armor and Muscular are subjected to this by Ultron during the I-Island attack.
• You Are What You Hate: Izuku's "The Reason You Suck" Speech to Gorr nearly title-drops it:
  Izuku: What are gods to you, huh?! Terrible beings that cause nothing but pain and suffering onto others without a care in the world?! Immortal and all-powerful deities who torture for fun and enjoy inflicting pain on others! Now, who does that sound like?! Who told me earlier tonight he was immortal and all powerful?!
  Gorr: YOU DARE-
  Izuku: I DO! Face it, Gorr! You've become everything you hate and more! The God Butcher?! No! You're Gorr, God of Hypocrisy!!
• You Didn't Ask: When All for One asks Loki why he never mentioned having a nephew, Loki says he never asked. When Loki later asks why All for One never mentioned he has more Nomus, All for One replies he never asked. Loki is upset by the turnabout.
