Izuku gasped as he peered down from the cliffside, staring at something in the dark ravine. "Kacchan, look! It's a-"

"Out of my way, Deku! You're too loud!" Katsuki sneered, pushing him none so gently as he cried out in slight pain. None of them noticed that the push had been a little to forceful, thus ending up with Izuku on the ground at the very edge of the cliff.

His lips trembled, as tears threatened to come out from his eyes. "That hurt a lot, Kacchan!" he cried out, as Katsuki scoffed at him.

"Yeah, right. Maybe if you weren't such a quirkless Deku, then maybe that push wouldn't hurt so much!" he exclaimed, smirking at his friend as Izuku tried not to cry at the insult.

Neither noticed the crack under them until it was too late.

It honestly wasn't supposed to happen, and yet it did. He gasped with wide eyes as his very own life flashed before his eyes. He tried to reach out his hand, to reach out to Katsuki, who was staring at him in shock, trying to process what just happened.

If only he had been more careful...!

Izuku Midoriya is a child whose dreams have been heavily crushed (but he could still do it! he just has to try-!) ever since he had found out he was quirkless. As he fell from the tall cliff and to his eventual death, he watched as his friend (or was he really?) attempted to reach out to him (he was too late to react- oh god why-) with a panicked face.

Is Kacchan... worried about him...?

How nice of his explosive friend to care.

Izuku idly wondered why some adults think that death is fast and painless. As he waited in agony for his impending doom, he could already feel the pain that would come- and he crashed headfirst on the hard ground, painfully.

It hurts so much- he's so in pain that he couldn't think straight- he can't even see clearly anymore- is it his blood pooling around him-? Wha-

And so, overwhelmed by the pain, Midoriya Izuku ceased to think as he passed out and was on the brink of death, only to be saved by Katsuki.

Or so what everyone thought.

Foo Fighter's objective was fairly simple: protect the discs and eliminate everyone who tries to retrieve them. They wondered when it all began to get complicated.

Perhaps it was when Jolyne Cujoh and Hermes Costello defeated them. Or maybe it was when they were on the verge of death, when suddenly she was saved by Jolyne giving them water. Or maybe, it was when they decided to team up with them to protect Kujo Jotaro's memory disc from Pucci.

Either way, their life had gotten very complicated really fast. They were just a colony of planktons trying to protect some priest's disc collection, which, come to think of it, isn't exactly a normal thing for planktons to do, but still. Having no other purpose, all they did was follow the orders.

And then Jolyne came along and made her realize and appreciate the wonders of having your own consciousness. Honestly, they owed a lot to her, and to return the favor, they decided to defend her father's disk up to their last breath.

Did they regret what they did? No, not really. They're glad that they were able to meet and be friends with Jolyne and the others. If it weren't for her saving them, they probably wouldn't have realized how beautiful the world around them is.

And so Foo Fighters disappeared in the wind, waiting for the clutches of death to bring them to the afterlife (if planktons could even go to the afterlife).

As soon as Izuku disappeared down the cliff, he immediately snapped out of his shocked stupor, scrambling in panic as he went down after the green haired boy. "Izuku!" he yelled, eyes wide with worry and fear for his friend.

He spotted the boy lying on his back, surrounded by blood and dust. Katsuki quickly carried Izuku on his back and ran towards the nearest person (with great difficulty) he could ever find, all the while screaming about needing help to heal his friend.

"P-please help-!" he gasped out as he approached a nondescript man, passing out from exhaustion out as soon as he uttered the words. The man, flinching at the sight, immediately dialed a hospital as he worryingly stared at two children covered in blood.

What happened afterwards was a blur to Katsuki.

But the important thing is that Izuku was alive. He was on the verge of death, bleeding tons of blood, but he's alive. Katsuki felt tears pricking on the edge of his eyes. He hadn't realized how much his friend (?) had meant to him.

Oh god, just what would Izuku think about him if he ever woke up? Katsuki doesn't think he can stomach the thought of his friend's reaction.

Foo Fighters is... confused, to say the least. What exactly are they doing in a child's body?

The child's mother (or at least that's what they assumed) was crying a bucket load of tears (probably enough to revitalize them, F.F. idly thought) as she hugged them, or rather, the body of a dead child that they had invaded.

He wondered when they'll notice that the kid doesn't have a pulse, but instead, is swarmed by a hive mind of intelligent planktons.

But all of this happening right now doesn't explain what exactly are they doing here. They're supposed to be completely annihilated by Whitesnake- or Pucci, as F.F. discovered. In fact, they remembered the exact command Annasui said to them and the exact words of gratitude they told Jolyne before they died.

Wait, why do they still have their memories? They died, so should they be revived by the disk, they wouldn't be able to recover their memories as they would be a different colony of planktons.

Hm, perhaps they shouldn't think about things that don't need to be answered right now, and instead worry about the current problem at hand: the dead kid they just finished extracting the memories out of. And by god, was this kid pitiful as hell.

Question is, should they tell the truth to the mother about her real kid being already dead and that she's only hugging his husk of a body that's currently being hosted by some plankton who gained heightened intelligence after having a disc thrown at them?

...On hindsight, that probably wouldn't be a good idea.

So should they impersonate the kid, much like what they did with Atroe?

Probably, since they didn't really have much of a choice, anyway.

On the plus side, they'd be able to infiltrate the human society without any hassle while also learning more about it (to be honest, they're kind of curious at these 'quirks' that people seem to have) but on the down side, their actions and decisions (especially 'Quirk' usage) are highly monitored by said society since this isn't like Green Dolphin Prison anymore where nobody would give a flying fuck if you assault someone so long as you know what you're doing.

Foo Fighters does not know what they're doing here.

Overall, they'd say that the good outweighs the bad. Plus, they could also join this so-called 'Hero School' and be a 'Hero' just so their 'Quirk' usage wouldn't be so limited. Being a 'Villain' is also a viable option, but they didn't really want their new (stolen) identity to be objectified by everyone as 'evil.' Not only that, but being constantly chased by the law is a big hassle for them.

It was decided, then.

Foo Fighters would impersonate Midoriya Izuku with no one the wiser while also trying to make a new identity and memories for themselves by living their (or rather, 'Izuku's') life to the fullest.

AN: idk if i'll ever continue this. i just really want to attempt the "canon cahacter dies and gets reborn as another canon character" trope with one of the prison gang :P (i i hope i inspired someone enough to continue this (or at least create another story with a similar concept) because honestly i don't think i'll ever continue this lol) well, if someone does want to continue this, you can. you don't even have to pm me or anything lol. you can totally use this idea and stuff.
