Overdrive: A MHA x Male Reader Fanfic

Climax! Overdrive 10%!

Todoroki's POV:

"L/N! What's going on?" I ask. Instead of getting an answer, I get shoved out of the way. I look next to me and see that L/N blocked one of Stain's swords. Stain then kicks L/N away. I focus my attention back on Stain. I used fire to send him back, but he just walked through it. I sent a stronger blast of fire. The stronger blast worked, and I quickly followed up with a larger ice wall.

"What did that other guy do to Stain? He's much more powerful now!" I yelled. Stain then cut my ice wall.

"Ya blocked your own field of vision against an opponent who's faster than you. Rookie mistake," the Hero Killer said.

"Come get me then!" I yell, getting ready to shoot more fire at him. Stain then threw knives into my arm, preventing my fire attack.

"You're good, kid. Unlike him," Stain with completely red, murderous eyes.

"Watch out!" I yell at the down pro. Suddenly, Midoriya jumped and grabbed Stain, and then dragged his face against a wall.

"Midoriya?!" I yell out.

"I'm not sure why, but I'm able to move now!" Midoriya explained.

"So he has a time limit," I say.

"No. That kid should've been the last one freed. I still can't move a muscle," the downed pro says. Stain then elbows Midoriya out of the way, sending him to the ground.

"Midoriya dodge!" I yell and send ice out at Stain. Midoriya dodges and runs back to me.

"He swallows a person's blood to freeze them! Just like what L/N said. But I was the one freed first. I've got three different guesses why. His quirk could be less effective the more people he uses it on. The amount ingested could play into how long it works. Or there could even be a difference based on a person's blood type," Midoriya explains. We then state our blood types.

"So you've figured it out. Bravo, very impressive," Stain says. We then contemplate our next move. Midoriya is going to fight him up close while I stay back and blast him with fire and ice. I then think about how I worried about Iida, and how I talked to my mom. Suddenly we hear L/N behind us.

"OVERDRIVE 10%!"

Your POV:

"Overdrive 10%!" I yell out as my body begins to change.

My body began to harden, just like Kirishima. I grew taller and gain more muscle mass. My eyes glowed (favorite color) and Lava began to spew out of my mouth. My Sharpened Wrist Swords came out of my wrists. Then ice and fire began to come out of the cracks in my hardening on their respective sides. My skeletal system was replaced with Platinum, making my teeth and Sharpened Wrist Swords metal. My hair stuck up and was engulfed in green fire. Finally, two exhaust pipes came out of the top of my wrists, with the ends facing me and small engines in my wrists.

Everyone looks back at me, surprised at my transformation. With an insane boost of speed, I rushed Stain. I drop-kicked him and sent him flying back.

"L/N, what's happening?" Deku asks.

"This, my friends, is Overdrive at 10%," you say.

"What's Overdrive?" Todoroki asks confused.

"It's when I push my body to its limits and use multiple quirks at once. My suit can adjust to most of the changes," you explain.

"I thought you had a limit of six," Iida said confused and grunting.

"That's a lie, sort of. Six is a safe amount, I could only use six and have Overdrive at 1%, but not much would change. My real quirk allows me to copy one's Quirk DNA, and add it to my quirk genome. This allows me to copy an infinite amount of quirks," you explain further. "No more questions, we got a hero killer to lock up."
