It's a normal day at school.

"These career choice forms are useless for you lot, since you all are going to be heroes anyway!" Izuku's teacher exclaimed in an exasperated manner, throwing away the forms as everyone cheered noisily.

Katsuki slammed his hand on the desk. "Don't lump us in with these losers, teach!" he yelled arrogantly, ignoring at the angry responses he got. "We all know that only Izuku and I are going to UA to become real heroes!" he added, before letting out small explosions to cut out the others from protesting to his statement.

Izuku rolled his eyes, but didn't deny his statement. After all, despite being dramatic about it, what Katsuki said is actually true; they both are going to UA, although their reasons might vary a bit.

While Kacchan wanted to become a professional (if not the number one) pro hero, Izuku, or rather, Foo Fighters, only wanted to become a 'hero' just so he could get away with using his 'quirk.'

But was it really a quirk, though? Foo Fighters was just being itself: a colony of plankton with high intelligence and slight affinity for water.

...Okay, maybe that did sound like a quirk, but still. The big difference is that he isn't human- he isn't 'Deku.' He's just pretending to be. And honestly, if he had been more sensitive about human emotions, he would've felt at least a small amount of guilt for using a dead person's identity to infiltrate the human society.

Alas, high intelligence did not come with human emotions, only a great sense of curiosity and rationalism. Also, they're a colony of planktons; they don't exactly understand how human empathy works.

But anyway, back to the topic at hand: Foo Fighter's- Midoriya Izuku's great attempt at hiding the true nature of his quirk.

It all started with him telling (read: lying to) his mom that his head hurts, and that he felt something moving inside his body. Of course, being the concerned mom that she is, Inko scheduled him for a check up (which led to getting an x-ray) only to find out that his son had an actual quirk.

F.F., after finally properly sorting through all of the real Midoriya Izuku's memories, feigned an excited expression after his mom told him about the check up's findings.

Seriously, trying to explain to everyone about how you are your own quirk (or in his case, a Stand) would only amass confusion. Not to mention the amount of prodding scientists that would be after his ass if he publicly announced that he's a literal colony of planktons.

Izuku does not have enough time to deal with that kind of shit. He wants to be free and not experimented on, thank you very much. Also, no. He is not paranoid that someone would eventually find out his true nature and then steal his intelligence. Not at all.

The bell suddenly rang, signalling the end of class as Izuku was snapped out from his buzzing thoughts. He sighed, gathering his things as Katsuki approached him with a scowl. "Oi, 'Zuku."

He looked up at his explosive friend, raising an eyebrow. "What?" he asked, perhaps a bit too flippantly. "You need something, Kacchan?" he asked, tilting his head as Katsuki scowled at him.

"Like hell I'd need something from you," he grumbled, before straightening up a bit. "I'm going to the arcade to the others right now. You want to come with us?"

He hummed, contemplating his options.

If he'll come with Katsuki, he might miss some action packed hero vs. villain fight to be watched (live, not on television) and analyzed. On the other hand, if he doesn't go with him, Katsuki might call him a loser then leave the classroom without him.

...It was pretty obvious which choice Izuku made.

He stared at the literally slimy person with a bored gaze. "What?"

The slime monster gave him a crooked grin, eyeing him with interest. "Great, a kid. Say, mind if I take your body for a bit?" It said, blinking before suddenly attacking him with a whip-like slash.

Izuku narrowed his eyes, jumping a few good meters away to avoid the attack before smirking at the sludge monster's words. "What if I do it instead?" he asked, dropping his backpack before charging so suddenly that the villain hadn't had the time to react.

"Wha- ARGH!" he howled in pain as Izuku, finally in his plankton form, had invaded his body and managed to suck up most of the moisture from the bulk of liquid mud.

After finally turning the sludge into a dry husk of soil, Izuku stepped back to admire his work, as he wiped the remaining liquid on the side of his mouth. "Eh, you'll be fine. It's not like I took all the liquid," he remarked, picking up his backpack from the ground.

The villain just screamed at him, probably blinded by rage.

Izuku just chuckled quietly, before blinking at the sound of the ground being roughly landed on. "Huh, must be a hero," he mumbled, turning to the source of the sound.

His eyes widened in shock. "All Might?!"

The villain was screaming even louder right now.

"Fear not, young man, for I am here!" the number one hero exclaimed jubilantly, striking a pose. He looked around the area before finally noticing the pile of dry mud besides him. "I-is that the villain?" he asked, unsure.

Izuku smirked, puffing out his chest in pride. "Yep! I did it all by myself. Take him down, I mean," he proudly stated, as the All Might approached the sludge villain cautiously. "I, uh, did that with my quirk," at the hero's piercing stare, he explained quickly that he was forced to used it as the sludge villain attempted to invade his body.

Only one organism is allowed to live in Midoriya Izuku's body, and that's Foo Fighters! (Of course, he didn't include that bit in his explanation.)

The pro hero let out an impressed hum. "Excellent work, young man! May I ask, though, what is you name?"

"Midoriya Izuku. It's an honor to meet you, sir All Might!" he exclaimed, before scrambling for something in his backpack. "Here! Can I please please please have your autograph?" he pleaded, taking out a... 32 oz. water bottle? Yeah, he supposed he could work with that.

Now, an average person might have a more... intense reaction after meeting All Might himself. Not Izuku though; to be perfectly honest, he's just impressed at the number one hero's prowess, so much that he even had a notebook dedicated to the man's various quirks. Quirks, because it's just impossible for All Might (judging by the impressive and, as some might say, impossible feats he made) to have one.

Yeah, you could say Foo Fighters is a bit obsessed at the concept of quirks.

Not even a slightest bit bothered by the odd choice of object to sign, All Might uncapped his marker (where did he even get that?) and signed the bottom of the bottle. "It's no problem, young Midoriya!" he said, before taking out another water bottle, this time an empty one (okay, seriously, where the hell does he get all these objects from?) and stuffing the screaming lump of soil inside it.

Izuku had to stifle a laugh at the ridiculous sight.

"Well, then. I'm off! It was a pleasure to meet you, young man!" And with that, All Might leaped of as Izuku stared at him, sipping on his water bottle.

"Huh, I just met All Might," he mumbled to himself. "And I got an autograph from him."

"This is not how I'd imagined my day would go at all."
