And another one as well! Wow, I am on a roll, aren't I?
Those who Are Worthy
(Inspired by N/A)
In the past, All Might chooses Izuku to be his successor, and grants him the power of his quirk.
Unbeknownst to anyone, they are being watched...
In the present day, Izuku, Bakugo, and Ochako have been kidnapped.
During a trip out, under U.A.'s guidance, Class 1-A was attacked by a group of villains, and Izuku is captured by them. Bakugo and Ochako had tired to go after him, but they had been knocked out by the villains and captured as well, the three of them dragged away and forced into submission by their kidnappers.
In the hidden base of the villains, the three students are confronted by the five villains, who go by the names of:
Henshin Obakes, a man with a mutant quirk that leaves him a horrifying looking monster.
Kisei Abe, a boy with a disintegration (I.E. villainous) quirk who is locked in a mechanical suit.
Sachie Aiuchi is a masked and fully clothed assassin - armed with swords - with a sex quirk, in that if she touches someone's bare skin with her own, she can immediately bring them to orgasm.
Riki Aimoto, a quirkless girl much like Izuku, who shares a similar hobby of analysing quirks.
And finally, their leader Iyashi Gushiken, a girl with the heroic quirk of self-healing (meaning that she's functionally immortal), and a Hero-in-training and student of Isamu Academy High School's Class 1-A...
And she wants One for All.
As it turns out, Iyashi and Riki had been the ones to spy on All Might and Izuku back in the day, as they had been going to the same school as both him and Bakugo (that being Aldera) and had happened upon Izuku and All Might after the Sludge Villain incident when the latter offered the former his quirk. Since then the two girls had been spying on the two of them, learning as much about One for All as they could, and now Iyashi had come to collect what she believed to be hers.
However, Izuku refuses to give it to her, and she resolves to find a way to take it from her.
From there, Izuku, Bakugo, and Ochako are kept hostage by the group of villains, and they assume that they are just like any other villain, only doing things because they want to and refusing to use the quirks and skills at their disposal for good.
But as they slowly get to know these villains and how they got into these circumstances, they realise that they are anything but willing to be villains.
Henshin was forced run out of his home at a young age and forced onto the streets by mutant haters due to his physical appearance, and had to resort to petty theft and crime in order to stay alive. He is actually a very gentle person who has been screwed over by those who hated him just for his appearance.
Kisei's quirk actually works against him, as instead of disintegrating everything around him (like Shigaraki's), it instead disintegrates himself. He's been living inside a sealed containment suit meant to stop the spread of his quirk, meaning that he is now little more than a skeleton with organs and a few strands of muscle holding him together swimming in a puddle of his own melted skin, and only has less than a month left to live. The metal suit was the only thing still keeping him alive, but it had only been made by Henshin and Riki, as no one in the hospitals had wanted to help someone with a villainous quirk. They had been more than content to let him die.
Sachie's sex quirk marked her as a freak by her fellow children from a young age and led her to be bullied and shunned by everyone around her due to the taboo nature of sex, all of them labelling her with the worst stereotypes and degrading names imaginable. Worse yet, her parents sold her off as a sex slave and prostitute at a very young age, forcing her to earn them money before the gang of villains she was a part of freed her from her slavery and trained her to defend herself.
And Riki had been living under the thumb of Iyashi for years, suffering from very much the same kind of quirkless discrimination from her peers as Izuku had, only this time her main bully had forced her into her service over it. She is very much like a villainous version of Izuku, but with more realistic depictions behind it.
All four of these villains are not here by choice. None of them chose to be where they are now, and all of them are just trying to make the best of the terrible circumstances that they have been forced into. The only one who wants to be there is Iyashi, the hero student, and she was the one to assemble them all as a single unit. She had promised them a family and a home, a safe place for the first time in their lives. What were they suppose to do, turn it down? It was the first good deal that they had heard in a long time.
None of the kidnapped trio have an answer for them.
Soon enough, Iyashi grows impatient, and brings a knife out, threatening to kill Bakugo and Ochako if she doesn't get what she wants. To the students' surprise the villains protest this, believing that this is a step too far.
However, Iyashi silences Riki with a forceful kiss, and cows the others into complacency as well.
Iyashi and Riki's relationship is a twisted deconstruction of the BakuDeku ship, as Iyashi has just as many parallels to Bakugo as much as Riki does to Izuku, including his pride and various ego issues. Their relationship is an abusive one, one where Iyashi holds all the power over Riki, and Riki fawns over Iyashi despite all of the abuse that she puts her through.
It is a disturbing relationship, and it is one that makes both Bakugo and Izuku deeply uncomfortable.
Iyashi then puts a knife to Ochako's throat, and demands Izuku give her One for All. Realising that his best friend is now on the line, Izuku relents, giving Iyashi One for All.
She runs her knife across his hand, bringing out a long line of blood and letting it drop onto her tongue.
She waits, and waits, and waits. And then, with a surge of energy, she feels it. One for All swirls in her gut.
Coming to the conclusion that both the hostages and her minions have served their purposes, Iyashi stabs Izuku, Bakugo, and Ochako in their knees and activates a failsafe she had installed in their hideout, setting it on fire whilst she escapes. To the students' surprise once more, the villains, having not been comfortable with the kidnapping plot to begin with and feeling betrayed by Iyashi's attempt to kill them and cover her tracks, are the ones to drag them out of the building before it burns down.
In the aftermath, Izuku tries to summon One for All to his side, but couldn't do it. He was quirkless once more.
Back with Iyashi, she returns to her Class 1-A in Isamu to show off her new power. As it turns out, everyone in her version of Class 1-A are dark parallels of Izuku's, and they all share the same goals: to do whatever it takes to climb the ranks of hero society, and claim as much fame and glory as they can.
However, Iyashi finds out that her plan to kill her old contacts didn't work, and that both her former prisoners and villain minions are still alive. Realising that they might be the only ones that can stop her plans are still alive, Iyashi sends her classmates out to eliminate them.
Now with dozens of fanatical hero wannabes on their tail and about to kill them, Izuku, Bakugo, and Ochako are forced to rally the villains to their side in a desperate struggle to survive.
And with nothing left to lose, the villains are forced to agree to their terms as well, and they all prepare for the fight of their lives.
And the fight comes for them, as Iyashi's minions comes down hard on them, bringing the fight of their lives down onto them as Iyashi leads them into the fray and brings hell down upon the villains and students.
However, as the fight drags on, and as Iyashi's healing quirk begins to evolve and compensate for the damage that One for All does to her, she finds that that very same quirk is beginning to overload inside her body with each passing moment, something that the combined force of students and villains decide to take advantage of as they press the advantage against the rogue hero wannabes.
And soon enough, they get reinforcements in the form of U.A.'s Class 1-A and teachers, turning the tide against the rogues.
The formerly kidnapped students and villains then turn their attention to Iyashi and begin to unload onto the superpowered hero wannabe, throwing everything that they have into her as One for All begins to tear her apart and Izuku and Riki lead them in picking her to pieces, shouting out orders to them on how best to deal with her.
And soon enough, it is Riki who delivers the final blow, landing a hard hit to the head and sending her former bully spiralling to the ground, her admiration for her finally wilting and dying.
And so does Iyashi. The amassed energies of One for All cannot be passed down to a tenth successor, especially one with a quirk. One for All tears Iyashi apart, and she dies from her own ambitions.
And then, so does Kisei. His suit had been damaged and torn open in the battle, and now nothing is stopping his quirk's accelerated decay of his own body. All the villains that he had called his friends can do now is surround and comfort him as he passes on, mourning the loss of their dearest friend as they share his last moments with him as they watch the sun rise in the distance.
In the aftermath of the battle, Iyashi's class are expelled from Isamu and arrested for their crimes, and the former villains are arrested as well for their part in the kidnapping. However, because of the testimonies of Izuku, Bakugo, and Ochako, the three surviving villains in Riki, Sachie, and Henshin are able to get reduced sentences and soon visit U.A.'s dormitories to see Izuku, having been put on probation and sending the rest of their sentences paying off their crimes by helping the heroes in vigilante work.
Izuku offers to let them stay with him once their sentences are over, and they agree, and they all toast a drink to Kisei, mourning his death and celebrating his life.
And with that, this story ends.
