I believe if Momo Deku and Ururaka fused it would be like Edds ability’s from full metal alchemist Anything they touch they can turn into something else with the necessary components and since Momo can make anything well you can guess the rest.

This is my second time reading this fic, and I just got this idea. Izukus fusions are stronger than the people that make them with stronger quirks, so you could have his hero name be Ultimate, then when he fuses with other heroes just add ultimate to there hero names for the fused heroes. Like Ultimate Uravity, Ultimate Red Riot, even Ultimate All Might as examples. Just an idea.

Kacchan's right. Badass as the triple fusion is, it's too dangerous to use it as anything but a limit break, for lack of a better term.

O hai Mummy-sensei. :p
(He'd kill me for that quip.)

Breathe... You got this.

Lay off, Shouto. Seriously.

Ooh, someone hit a nerve. Isn't that exactly what you do though, Shouto? Use only half your Quirk?

Freezerburn certainly does, Kacchan.

...Shit. That certainly adds up. Meaning he better not use triple fusions unless it's really about to hit the fan.

Note to self: Do NOT piss off Recovery Girl.

Ooh, beach weekend!

D'aww, lil sister. :3

Mad laughter sounds about right for a fusion of those two. :p

O hai Yagi-sensei.

Pfft. He would!

Adorbs lil sis wants to meet a fusion of big sis. Not exactly the one she was hoping for, but one can be arranged.

Ah, that could be useful for mostly-peaceful takedowns.

Ooh, that paralytic lasts.

Ah, Tsu knows. She's also being blunt with the Number One.

Heh. Comic relief. XD

First the good news...

And then the OH FUCK news.

Take that chance to get the hell outta Dodge, Jirou!

Welp. You gave it your all. Going down swingi-

"loooong day" That's putting it mildly.

Take this chance to get away.

O hai Shouto.

Seriously, man, what is yer prob?

Heh. Ice bomb.

Ouch. He's gonna feel that in the morning...

You dipshit. *facepalm*

Aoyama and Hagakure. They seem to be in good shape. Back to rescue Shouto from his own idiocy.

Dammit!

Well, that seemed to work. Now to get out of the new mess.

And the cavalry arrives!

Take a load off, all of you. Heaven knows you've earned it.

You're gonna have to damage it a lot more to wear it out, man.

O hai Kirishima and Iida. Nothing to see here, just a monster dropping in.

OW OW OW OW OW OW OW

Hmm... Not sure what to call that, but hell if it wasn't impeccable in timing.

Ooh, me likey the mutation.

The barn. He made the barn a bomb.

Aizawa is safe. Reckless or not, that's good.

Aw hell. The theory is solid though.

"Figure your love lives out later!" lel

Son of a bitch.

This'll cost them, but not doing it will cost them more. Fuck it.

Welp. So far, so good. And, yeah, good bloody luck figuring out how sex is determined.

Katzuchako's mutation should be fun to watch.

The class could even take it down before the faculty arrive.

It is rather odd. Hella useful and versatile though.

Shut up, Mineta.

Why so hostile, Shouto?

Not many good options... Really not seeing any way out elsewise.

Izoru's mutation is PERFECT for this!

...What the shit? He can do that?

It seems his fusions default to female if a woman is involved. Fascinating.

Noumu is down. Out? Who knows?

Uh-oh.

Yer gonna have to get that gunk down Shigaraki's throat to take him down, which will of course be fatal to him. Can you live with that?

Yeah, that's gonna be a problem.

He's on day 2 of his first year and he has fans already. :3

Floaty Deku lel

I have no doubt that All Might or someone at the school would do this for just anyone, but it's certainly a convenient cover story.

Rock-paper-scissors. Ooo-kay.

Izuchako it is.

Meteor Storm could be a useful super move.

Yeah, don't cripple yourself or lose your lunch.

Acid... How will that mutate?

Izuna. And maybe she controls the pH on demand? Can she make it alkaline?

Oh dear. RIP Gym Gamma. XD

They don't seem disgusted. That's a good sign?

O hai Moku. Let's do this! LEEEEEEROY JENKINS!

Transmutation. Ooh, this is some real gourmet shit here.

And the crowd goes wild!

That was quite the bout. Now to get at Shouto. Good luck with that one.

Nothing short of All Might, eh? Would his chosen successor suffice, Shouto-kun?

Ashido WANTS to try a fusion! Even those not actively lining up absolutely loved it! Again I say, SUCK IT ALDERA!

Hmm, a spar between Kacchan and Moku. This could be fun.

What did he include, bricks?

Bootleg All Might plushie lel

Smaller tanks means more of them which means more bigga booms. :3

Ooh, paired with YaoMomo. This combo of Quirks could be fun. Plus I don't see a story about All Might suddenly losing 200kg showing up, so...

Yeah, might wanna add more cloth, kiddo.

Enter Iida. Go time.

Oh, what awful acting. XD

He fights better than he acts. Now let's check in on Izubean and Shouto.

Welp. That went to hell in a handbasket fast. YaoMomo isn't doing much better. Time and options are running low.

Here goes nothing.

SUCK IT, ALDERA!

Ooh, Kacchan has a new friend. He'll never admit it, of course.

BREATHE, Izubean.

O hai Iida.

This test should be interesting. How might his Quirk factor in this time?

Ah, YaoMomo saves the day.

Hail and well met, Kirishima-kun.

Heh. His fusion material doubled as a chair for sensei. :p

Hmm... Good call not using it right away.

Wowzers.

Say, I just had an offhand thought... Can the fusions perform material fusions?

Damm Todoroki is an asshole. Like seriously he’s an ass. Wow. That’s literally part of Izuku’s quirk, he’s just jealous he’s been upstaged.

Yeah, best to be careful about who you fuse with now, kiddo.

Well, good thing you were gonna talk to her about this anyway.

Um... At least Izubean will be a well-fed dead boy? :p

Do I wanna know what Bakugou sent to All Might?

Oh. Merely blunt as a spoon. That's... not exactly harmless, but not what I was expecting.

Ah, that would explain the damage discrepancy. Uraraka, Bakugou, and Yagi are all correct. That's neither fair nor smart.

Logic, kiddo. Use that logic of yours in extending your compassion.

They'll find out within a few months anyway, so just keep your fusion pool smallUA staff and Hero Course students, like Yagi-sensei said.

*snort-laugh*

So Katsuchako has gravity control from Izuchako killer queens ability from Jojo’s. Really fucking cool.
