History Fanfic / VillainNotebookForTheFuture

*** Had he not intervened with [[spoiler:[[BloodKnight Muscular's]] [[CurbStompBattle fight]] this early, Koda would've gotten back his respect for heroes, nor would he go onto the path of supervillainy.]]

The fanfic spawned many side stories, including the one-shot '''Nedzu's Deal with Eraserhead''', which can be found [[https://archiveofourown.org/works/39630618 here]], and a crossover with another MHA fanfic of his, called '''False Notebook for Villain Love - An Interdimensional Exchange!''' which can be found [[https://archiveofourown.org/works/44718964 here]].

* AssholeVictims: Mastermind's, and by extension the [[spoiler:league of SuperVillains']], victims did deserve being attacked by them. These victims dabbled in extortion, selling cheaper quality items at inflated prices, racketing, and/or offshore funding, amongst other things. [[spoiler:And then there's those like [[AbusiveParent Endeavour]].]]

** and another of Tenya, when thinking about what nefarious thoughts lie inside his mind, Izuku, his real identity, only has one thought.

** It's also the reason why [[spoiler:Twice and Kouro joined the league of SuperVillains]]. Both weren't shunned away by Mastermind because no one else took their problems seriously, and he did help them out with said problems when they first met.

** Apart from those really close to him, like Kurogiri or his sensei, nobody believed Tomura when he claimed that [[spoiler:the League of Supervillains stole his guild name]].

** The [[spoiler:League of ''[[InsistantTerminology SUPER]]''villains]] don't condone murder or otherwise unnecessary violence. They turned away any prominent recruits that are inclined to actually kill anyone. They don't even tolerate notorious serial killers either, much like Stain [[spoiler: or even Muscular]].

** The league of Villain's attack at USJ went into action, with Mastermind and the [[spoiler: league of SuperVillains]] barging in by accident.

** Had Eraserhead not confronted Izuku early, Izuku would've never managed to get the potential to replicate his Erasure Quirk [[spoiler: as well as reversing it to create a Force-quirk activation-ray that even nullifies [[PowerNulifier Erasure]].]]

*** his thunder effect machine '''Kara-Thooom'''

*** and from there, Insisting that he's a '''[[InsistentTerminology Super]]'''villain, namely because of his [[EvenEvilHasStandards standards]], that being what he's willing/not willing to do, or approve of other's actions.

* SpringtimeForHitler: Izuku planned to not win the sports festival, only advance enough to gain legitimate recognition for his inventions. He breezed past the first round (which was the earlier one he had planned to win) but couldn't afford to fail the second round thanks to Kachan picking him to join his group and, thanks to the malfunctions on the gears he made for each battle, accidentally won against both Shoto Todoroki and Melissa Shield [[spoiler:, the latter having already gained One for All]] in the single combat round.

** Because of their intervention in the USJ, as well as [[spoiler: stealing their name, Shigiraki's hatred is now directed towards Mastermind instead of All might, much to his sensei's annoyance]]

*** Speaking of which, [[spoiler:Stain and spinner met soon after, with spinner now actually working for him instead of a group of villains only using Stain as a recruitment drive.]]

You've all heard the story: Izuku meets his idol All Might, Idol destroys his dreams of being a hero, Izuku becomes jaded and cynical, hates heroes, turns to villainy, and destroys hero society, sometimes with or without the aid of the League of villains. You know, Izuku became [[WesternAnimation/TheIncredibles1 Syndrome]].

** Izuku, in canon, was just a quirkless kid with low self-esteem who was at the right place, right time, to be picked as the next symbol of peace. Mastermind, as Izuku goes by in the fic, planned and worked on being a supervillain since the age of 4, and because of it not only has he gotten smarter than those with intelligence-boosting quirks, formulating plans that's mostly foolproof, but is also able to take on several pro-heroes along the way, including [[TheDreaded Eraserhead]], with his greatest example would be [[spoiler:actually pulling off an Eraser quirk ray that worked, and its opposite.]] Not bad for a still quirkless kid.
** Inko Midoriya, whose only power is light telekinesis, ups her MamaBear status by not only going after those whose kids tried to strangle izuku back then, teaching her son how to give himself a [[DeathGlare death aura]], but she's also the only person Bakugo never swears in front of, and for good reason.
** Melissa Shield, a quirkless child, [[spoiler: is now the current wielder of One for All.]]
* AdaptationalEarlyAppearance: several characters appeared earlier than their canon introduction, such includes the Gentle duo, Melissa and David Shield, Shinso, Mirio Togata and Sir Nighteye, to name a few.
* AdaptationalExpansion :
** The reason behind Shoto's trait of being a conspiracy theorist was because of Endeavour, in a attempt to get Shoto to use his fire more often in his childhood, paid off his children's romantic partners to say how cool fire quirks are, as well as paying for ads, specifically those that encourage the use of fire quirks, on Shoto's phone, which resulted in Shoto believing that someone's out to get him.

* AffablyEvil: Izuku is a [[CardCarryingVillain Text-book supervillain]] who loves to cause mayhem for the heroes, yet that doesn't mean he can't treat his enemies (the pro heroes and hero U.A. students) like friends who hang out on a daily basis, even leaving clues behind to the location of a hostage whenever he ever has one. This trope would extend to members of his own team. At worst, they're all the AntiVillain types.
* AssholeVictims: Mastermind's, and by extension the [[spoiler: league of SuperVillains']], victims did deserve being attacked by them. These victims dabble in either extortion, selling cheaper quality items at inflated prices, racketing and/or offshore funding, amongst other things. [[spoiler: And then there's those like [[AbusiveParent Endeavour]]. ]]

* ArmorPiercingQuestion: Izuku[[spoiler:, actually [[ClonesArePeopleToo Shinji]],]] gives one to [[spoiler: Stain during their fight in Hosu, questioning, since he wanted to bring a society of real heroes, when was the last time he saved someone. This question actually sticks with him from then on.]]
--> '''Mastermind Izuku[[spoiler: /[[OurClonesAreIdentical Shinji]]]]''': ''To me, a Hero is somebody who helps others even when they're not asked to! But you're just a butcher! When was the last time you helped anybody in need?!''

-->'''Tenya''': (internally) ''What inhuman thoughts lie behind that mask?''
-->'''Mastermind'''/'''Izuku''': ...I want [[TrademarkFavoriteFood katsudon]].
* BecauseYouWereNiceToMe: Izuku doesn't hold a grudge against Bakugou, even though he still treated him just like in canon, for this reason: he beat up those that [[HypocriticalHeartwarming treated him in a similar manner or worse]]. The reason Izuku became a supervillain is mainly to help Katsuki Bakugou become the best hero ever.
** It's also the reason why [[spoiler: Twice and Kouro joined the league of SuperVillains]]. Both weren't shunned away by Mastermind because no one else took their problems seriously, and he did help them out with said problems when they first met.

** Mastermind may be a Supervillain akin to a saturday morning cartoon villain, but he has evaded and outwitted many pro-heroes at every corner, including the dreaded Eraserhead, as well as responsible for many of their team's support items and robots at their disposal.
** Shigiraki, a PsychopathicManchild who speaks in gamer Lingo and at one point quoted Eggman's memetic speech from the [[WebVideo/RealTimeFandub fandub]], has nonetheless conjured many plans that his sensei approved of, including the [[spoiler: notorious bomber nomu attack at Hosu with a made up alliance with Stain so convincing, so well fabricated that those who had a legitimate connection with him [[CassandraTruth such as Spinner still has a hard time trying to clear his name]].]]

** Apart from those really close to him, like Kurogiri or his sensei, nobody believed Tomura when he claimed that [[spoiler: the league of Supervillains stole his guild name]].

** Of the EvilGenius trope, even Izuku knows that no plans are 100% full proof, and that there will be outliers that'll crash in that'll prove to be too much to handle even alone (such as [[spoiler: Eraserhead in the cake heist]]).

** The [[spoiler: league of ''[[InsistantTerminology SUPER]]''villains]] don't condone murder or otherwise unnecessary violence. They turned away any prominent recruits that are inclined to actually kill anyone. They don't even tolerate notorious serial killers either, much like Stain [[spoiler: or even Muscular]].

** Aside from their usual heist, Mastermind usually indulges himself in petty acts of minor villainy, such as walking on grass despite being told otherwise, or otherwise create a series of soup shops, with his only claim that the latter isn't heroic is that it was never made official or deemed so by an official at any point.

** At [[spoiler: Ingenium's (Tensei, not Tenya) Hostage plot]], Izuku ask for ransom, aside from the usual amount of money expected in this scenario,[[spoiler: the ''Hostage's own signature''[[note]] As it turns out, there's a practical reason for such a demand, as the [[FridgeBrilliance situation surrounding the signature would make it a collector's item]].[[/note]].]]

** They get admitted to UA academy, even if they applied to different courses.

** The Hosu Bomber incident still happened with the only deviation is that [[spoiler: Stain is actively fighting against the nomus, [[WhatIf whereas in canon, he only stopped one when it caught Izuku]].]]

** Had Eraserhead not confront Izuku early, Izuku would've never managed to get the potential to replicate his Erasure Quirk [[spoiler: as well as reversing it to create a Force-quirk activation-ray that even nullifies [[PowerNulifier Erasure]].]]

*** His intervention in the USJ attack [[spoiler: earned him Shigiraki's [[BerserkButton hatred]], getting him to amp up his future attacks in retaliation]].
*** Him getting too caught up in posing menacingly before his fight during the sport festival, after Mineta ''accidentally'' groped Mei Hatsume in their fight, gave enough evidence to Shoto to correctly deduce that he's Mastermind.
*** Had he not intervened with [[spoiler: [[BloodKnight Muscular's]] [[CurbStompBattle fight]] this early, Koda would've gotten back his respect for heroes, nor would he go onto the path of supervillainy.]]

** The heroes (Death Arms, Kamui woods and Mt Lady) get one when Mastermind, after saving Bakugou from the sludge villain, declares himself as a villain to the world. Mostly because it puts them in such a negative light, as they were all present on the scene longer than him and yet did nothing.
** Some time later, Izuku gets this when he encounters ''[[TheDreaded Eraserhead]]'' after his cake heist, knowing he's way out of his head going up against him.

** Hawks gets a little serious when he's notified of Mastermind's existence by his superiors; notably once he learns from them that [[spoiler: [[MesACrowd Jin]] is in leagues with them.]]

** Mastermind, and by extension his crew, get's one when they learn that [[spoiler: [[BloodKnight Mirko]] is in the area.]]

-->'''Mastermind''' : "[[BadassBoast It's a bad day for heroes when a supervillain has to do their job!]]"

** Mastermind's most trusted contingency plan against All-Might : distract him with [[ChronicHeroSyndrome saving a]][[BoringYetPractical cat up a tree]] before he could get to the area of the crime. The fact that it works says something.

** There are plenty of references to WesternAnimation/{{Megamind}}, with Shigiraki's rant to Mastermind at USJ being similar to Tighten's, and mastermind's use of a Frequent Kidnapping Card.

** Gentle's fight at the Mei prefecture construction company came straight out of the first bar fight scene [[Film/KingsmanTheSecretService Kingsman: the Secret Service]], including the actions and phrases.
** Izuku's freeze ray is inspired from many ice villain's designs, including Mr. Freeze's from Film/BatmanAndRobin.

--> '''Mastermind''': ''[[Film/SonicTheHedgehog2020 I was not expecting that! But then again, I expected not to expect something today so it doesn't count!]]''

* SpringtimeForHitler: Izuku planned to not win the sports festival, only advance enough to gain legitimate recognition for his inventions. He breezed past the first round (which was the earlier he had planned to win) but couldn't afford to fail the second round thanks to Kachan picking him to join his group and, thanks to the malfunctions on the gears he made for each battle, accidentally won against both Shoto Todoroki and Melissa Shield [[spoiler:, the latter having already gained One for All]] in the single combat round.
* {{Squick}}: One of their heist on a company had led to them seeing the higher ups in a... compromising situation.[[note]] they were indulging in acting like preschoolers, to say the least.[[/note]]

--> '''Izuku/Mastermind''': Well, Heroes, here we are! Unfortunately... you will be unable to stop the devilish machinations of Mastermind-''[[DramaticThunder KRAKATHOOM]]'', -and...
--> Mastermind and his colleagues struck their pose
--> '''Mastermind''': ''[[spoiler: THE LEAGUE OF SUPERVILLAINS!]]''

** The original League of Villains has their whole relationship between them changed [[spoiler: with mr compress and Twice joining Mastermind with the League of Supervillains before the League of Villains could even be formed.]]
** [[spoiler: Twice went to the League of Villains instead of the League of Supervillains]], and that was prior to the Hosu incident as well, [[spoiler: which was what inspired him in canon to join the League of Villains]].
*** How he met them was changed as well: [[spoiler: instead of Giran, who's now the main recruiter for both camps, he had heard of them through their unofficial evil soup shops]].
** Mineta [[spoiler: has [[OOCIsSeriousBusiness toned down his perverted traits and is actually serious about being an actual hero]].]]

*** Speaking of which, [[spoiler: Stain and spinner met soon after, with spinner now actually working for him instead of a group of villains only using Stain as a recruitment drive.]]

* SpringtimeForHitler: Izuku planned to not win the sport’s festival, only advance enough to gain legitimate recognition for his inventions. He breezed past the first round (which was the earlier he had planned to win) but couldn't afford to fail the second round thanks to Kachan picking him to join his group and, thanks to the malfunctions on the gears he made for each battle, accidentally won against both Shoto Todoroki and Melissa Shield [[spoiler:, the latter having already gained One for All]] in the single combat round.

** Nedzu introduction at the police conference is similar to [[Manga/DeathNote L’s]]

** Aizawa gets nervous when he pieced together from Nedzu’s explanation that Mastermind might be Quirkless;

** Powerloader gets one, and by extension Present mic even though his was Downplayed, when he sees Mei bringing an invention into the arena, one that he approved for Izuku '''ONLY'''.

** By technicality, Bakugo still won the sports festival (if only begrudgingly)

** by technicality, Bakugo still won the sports festival (if only begrudgingly)

** Ms Joke laughs when she realises that the bomb mastermind left after another one of his heists [[spoiler: was in reality a simple volcano science project, with Mastermind literally telegraphically pointing it out by [[ExactWords naming all the ingredients used, whilst making it sound like a threat]].]]

** Mastermind may be a Supervillain akin to a saturday morning cartoon villain, but he has evaded and outwitted many pro-heroes at every corner, including the dreaded EraserHead, as well as responsible for many of their team’s support items and robots at their disposal.

** Mineta’s move "grapezone grenade", was likely inspired by Piccolo's attack "Hellzone Grenade" from [[Anime/DragonBallZ Dragon Ball Z]].

** Mellisa Shield, a quirkless child, [[spoiler: is now the current wielder of One for All.]]

* AdaptationalRelationshipOverhaul: the canon League of Villains is mostly a CriminalFoundFamily type of relationship. Here, because of circumstances, the original members weren’t this friendly with each other, given that they’re now on two opposite sides.

* CallBack: during the police meeting, when briefly discussing the possibility of Mastermind being Quirkless, Aizawa recalls the time he met Knuckleduster, a hero who became a quirkless vigilante after an unfortunate encounter with a supervillain back in the spinoff MHA: Vigilante.

*** and on that note, most of these stories have Izuku becoming either disgusted or downright offended by the hero society, particularly about how nowadays heroes are more for show than practicality, enough that he stops being a fan of them. In this, whilst he does see the flaws in the hero society, he’s still a hero fan, and another motivation for his supervillainous activities is to make them better.
** of the EvilGenius trope, even Izuku knows that no plans are 100% full proof, and that there will be outliers that’ll crash in that’ll prove to be too much to handle even alone (such as [[spoiler: eraserhead in the cake heist]]).

*** And on that note, they only attack those who [[AssholeVictim deserve to have their dirty secrets exposed]] (regardless of how morbid or weird it might be).

** In an attempt to get [[spoiler: Tensei into joining them, the LoSV tormented him by playing with the brother’s shared OCD problems (pouring juice in the sink; throwing trash into the wrong receptacle, bringing in salty food… etc)]]

* InSpiteOfANail: most of the events and arcs from Canon still happen (with the possible deviation of the Gentle Criminal encounter, as it had happened earlier) with slight changes, as in:

* LoveEpiphany: sometime after the internship, Izuku starts to realise that he’s in love with [[spoiler: both Mellisa and Mei]], and asks Labrava for advice.

*** had he not intervened with [[spoiler: [[BloodKnight Muscular’s]] [[CurbStompBattle fight]] this early, Koda would’ve gotten back his respect for heroes, nor would he go onto the path of supervillainy.]]

** Tdodoroki's penchant for conspiracy theories; especially [[GilliganCut when it leads to ]][[TheCuckoolanderWasRight said theory being true]].
** comments on Mineta's body, especially after having a pervy thought.

** There are plenty of references to [[WesternAnimation/Megamind]], with Shigiraki’s rant to Mastermind at USJ being similar to Tighten’s, and mastermind’s use of a Frequent Kidnapping Card.

** Izuku’s freeze ray is inspired from many ice villain’s designs, including mr.Freeze’s from [[Film/BatmanAndRobin]].
