The Bad Time Hero (Male Reader x MHA)

Finals

Everyone went quiet as Aizawa faced the class.

Aizawa: Your finals are coming up.

Everyone looked nervous.

Aizawa: You'll need to use everything you've learned from your classes, the sports festival, and even your internships.  You have a week to prepare, you're all dismissed.

Timeskip

I sat in the locker room, pondering what I'd just been told.  I would be fighting All Might... alone.  The door opened, and Frisk walked in.

Frisk: Hey YN.

YN: Hey babe.

She sat next to me.

Frisk: So, you have a plan?  I don't think you want to fight All Might, so are you gonna just run to the exit?

YN: I wish it would be that easy.  All Might's too fast for me to just run around.  I'm gonna have to fight him at some point.

Frisk: Well... good luck.

YN: Thanks, Frisky.

She grinned, kissing me.

I made my way out to the testing ground.  I looked around, scanning the area.  This was the mock city that we used in the exam test.  I summoned two Gaster Blasters on my hands, flying into the city.  Suddenly, something hit me in the back and sent me flying into a wall.  I groaned, standing up and cracking my neck.  All Might stood there, his hands on his hips and that signature smile on his face.  He clearly held back with that punch.  I smirked.

YN: Come on, All Might!  I know you're stronger than that!

Three giant Gaster Blasters formed behind me, firing at All Might.  He simply ran through them, and I dove out of the way as he went for another punch.  Unfortunately, it was a feint, and he kicked me in the gut, knocking the wind out of me.  I went flying into a wall, spitting out blood.

All Might: Just give up, young Sans.  You're not strong enough to take me on.

YN: Heh.  You might be right, but while you're here, I've got a question for ya.  Do you think even the worst person can change?  That everybody can be a good person if they just try?

Suddenly, All Might was suddenly standing in a pitch black void.  He looked around, still smiling.

YN: I know that was kinda out of the blue, so here's a question... do you wanna have a bad time?

All Might turned towards me, seemingly unfazed by my skeletal form.  He took a step towards me but I held my hands up.

YN: Woah woah, I'd stop right there.  Cause if you take another step forward... you are REALLY not gonna like what happens next.

He took another step, and a bone shot out of the ground, uppercutting him and knocking him onto his back.

YN: Welp, sorry old man.  Let's do this.

He jumped up and I rushed at him, my fists bursting into blue flames, and punched him in the gut.  All Might went flying backwards, but a wall of blue bones erupted from the ground, stopping him.  I jumped up, drop kicking him through them.  He rolled on the ground a few times, before getting back up, still smiling but his eyes narrowed into a glare.  I grinned.

YN: You look frustrated about something.  That expression that you're wearing... well, I won't grace it with a description.

I concentrated, and suddenly Epic appeared next to me.

Epic: What's up, All Bruh?

All Might looked surprised as we both rushed forward, blue flames forming on my hands and purple flames forming on Epic's, and began punching him relentlessly.  After a few moments and about a dozen hits, we both jumped over him, punching him into the ground.  He laid there, unconscious, as the black space around us dissipated.  I grinned, and offered Epic a fist bump.

Epic: Welp, that was fun.  See ya, bruh.

Nezu announced over the speakers that I had passed, and I grinned.  I walked out of the arena and to the waiting room, where Izuku, Frisk, and Uraraka were just staring at me.

YN: What?  Is there something in my teeth?

Izuku: Y-you just beat All Might...

Uraraka: Single handedly...

Frisk: Nice job, baby.
