Everyone believe that All Might has finally finish off Vill, but Vill use a quirk call Illusion to trick All Might to use his final smash, now, it's up to izuku with his new Mastered All for One form.(MAfO=Mastered All for One)

(MAfO)Izuku: come on, Vill. i can't keep on waiting, you know.

Vill: impossible, how did you do that? how did you learn how to master it in a day?

All Might: he did it, he actually did it!!

(Back with bakugo and the others...)

Sero: look at him, he has change and he's not going crazy like the time he fight All Might.

Kaminari: and the time when he fought bakugo in combat training.

Kirishima: and at the U.A. Sports Festival.

Tokoyami: but look at his eyes, his eye color only turn black instead of his eyeballs turning black too.

Mineta: wait, so does that mean izuku learns how to control this power?

Ojiro: yeah, but he has one more power to mastered...

Tenya: ...All Might's quirk.

Bakugo: you better win, izuku.

(back at the fight..)

Izuku and Vill stared at each other and izuku launch himself to Vill, then Vill put up his arms to defend himself, but izuku was too fast and got punch in the face, then he landed on a pile of rubble.

Vill: grrr!! how is it possible!? how are you so strong!!?

(MAfO)Izuku: well, i trained like hell to be powerful than All Might

Vill: oh, you think your being cute?

(MAfO)Izuku: bitch, i'm adorable.(to women)

Vill: why..you!!!!!!

Vill rush towards izuku and trys to hit him, but he keeps on missing him.

(MAfO)Izuku: really? is that all you got? well, if we're going to make this fight interesting, i need hold back a little power.

Izuku started to throw punches at Vill and they both started to fight like crazy.

All Might: amazing....he hold back some power, yet he's still strong enough to hold his own.

Mt.lady: should we help him!? i mean, what if he gets hurt?!

Best Jeanist: no......let him fight, he's the only one who go up against Vill.

All Might: your right, izuku absorb the All for One from Vill and now he learns how to control it, it's up to izuku to finish this fight.

Izuku was blocking Vill's attacks, when suddenly, Vill uses a air-cannon on izuku, making a hole on his chest. Everyone stared in horror and never speak a word.

Vill: heh, with all that power, you are still weak—(punch in the face)

Vill got hit and izuku gets himself back up.

Vill: how!!?!?!!? i blow a hole in your chest!!

(MAfO)Izuku: well, the quirks you stole over the years, is now mines.

Izuku shows his chest is regenerating fast and that leaves everybody speechless.

(MAfO)Izuku: i even have the ability to copy people's quirks by looking at them and the best part, there are no drawbacks!!!!

All Might's eyes wided big at this one, izuku has all the quirks that Vill has. And now both of them resume their fight.

Vill: I WILL KILL YOU!!!!!!!!!!!!!!!!!

(MAfO)Izuku:*scoff* good luck with that!

Izuku dodge all of Vill's attacks, but none of them hit him.

(MAfO)Izuku: alright!! i getting tired of this, let's finish it!!!

When izuku was about to throw a final punch and it landed on Vill, nothing happen, then something happen to izuku. His eyes and his hair are back to normal.(!)

Izuku: oh no, how!? why!?

Vill: i see, since it's your first time using this power, you only have Temporary time to use it, but you wasted to much time.

Izuku: Fuck.......

Vill grabs izuku by the neck and starts choking him.

Vill: you shouldn't fool around like that, because you will die faster and it will be painful!!

Izuku: AAAAAAAAAAAAGGGGGGGHHHHH!!!!!!!!!!!!!!!!!!

All Might: IZUKU!!!!!

Kamui woods: we can't let him die!!

Endeavor: we need to save him!!

But then, a knife came out of nowhere and cuts Vill's shoulder, causing him to let go of izuku.

Vill: grrr...!! who did that!?

Stain: i did.

Everyone turn their attention to stain and look surprise, stain jumps from the broken building and lands next to izuku.

Stain: hey, you okay?

Izuku: yeah......thanks, but i don't have the watch.

Stain: i've heard of a explosion and ran my way here to save you, what happen to him?

Izuku: long story short, i finally learn how to control my power and i kick his butt easily, but i used too much time and i turn back to normal.

Stain: alright, can you do it again?

Izuku: i just said it, i used too much time, now i can't transform.

Stain: damnit! now what?

Izuku: for once in my life......i don't know.
