Overdrive: A MHA x Male Reader Fanfic

Y/N VS Saiko

"What the hell are you doing here?!" you ask Saiko.

"Do you really need to ask that, I got a job to do so I'm here to do it," he answers. Suddenly the lizard guy pulls out a huge-ass sword that also has multiple other blades tied to it. You look over at him.

"Someone's overcompensating!" you yell.

"Yeah, Spinner likes Stain a bit too much," Saiko says. "But I wouldn't worry about them, you got me to worry about."

Saiko throws multiple attacks at you, but you dodge. Mandalay orders everyone to retreat, and you try but Saiko won't let you.

"Come on fight back! You already know I won't let you run away," Saiko says. You keep dodging his attacks.

"Y/N since you can't get away, I allow you to fight, but run the moment you find an opening," Mandalay says. You smirk and sent a huge blast of fire at Saiko, which he tanks.

"Finally! Now let's see how much stronger you got!" Saiko yells. Saiko sends chains at you, you dodge most but some do end up hitting you. You run and try to punch him, but he phases through you and sends sharpened air at you stabbing into your back. You run at him with Super-Speed and punch him in the gut. His right arm then turned into a piston and he began to punch your head repeatedly. You then freeze Saiko in place. After a second you feel a hand grasp your ankle and pull you down. Saiko had phased through the ice into the ground!

Saiko then sent a huge purple explosion, blasting you into the air. He followed you up, but you grabbed him and moved him atop of you. You then bite your tongue as a large lightning bolt came down to strike him. But he blasted you away and faced the lightning bolt.

"Kamui!" he yelled and absorbed the lightning bolt.

"You gotta be kidding me," you say. Saiko then turned into a titan.

"YOU GOTTA BE SHITTING ME!" You yell and turn into a titan yourself.

You both begin fighting as Titans, with Saiko having the upper hand because of his titan's armor, but you are faster and have more experience as a titan. He probably doesn't know about the weakness. You also had a little trick yourself. You made an opening and created crystal armor around your hand and jabbed it straight into the titan's arm, completely ripping it off. Saiko grabbed it feeling immense pain, and you used the opportunity to rip him out of his nape.

"Well, that certainly was... Interesting," Saiko said. He then created a large explosion aimed at your neck. The explosion traveled straight through your neck and had enough force to send you flying far. You eventually crash into a building.

"L/N!" yelled the remedial students, along with the other students and Vlad King. You looked over and saw the group.

"That bastard could use his quirk after leaving the titan? And sent me here with one explosion," you say to yourself.

"Y/N what happened?" Mina asks worriedly.

"Saiko, my half-brother, is here. He's apparently after me and Bakugo," you say.

"Then we need to get you out of here!" Kirishima yelled.

"Later. Only me and All Might can beat Saiko, maybe Aizawa. The problem is I don't know where they are, so it's up to me!" you say.

"But you're injured!" Mina says.

"And? I'm the Beyond Hero: Overdrive! Nothing will stop me!" you yell.

"And there's that term, Overdrive. You seriously made that your hero name? Lame!" Saiko said.

"Damnit, he's here already!" you say. Kirishima and Sato charged him.

"L/N I'll take care of him and you two stay back!" Vlad said.

"Kamui!" Saiko yelled and a rift of sorts appeared from his eye, absorbing Sato, then Kirishima. He then oneshotted Vlad.

"Shit!" you say. "The rest of you stay back!"

"Heeeeeey Y/N!!!" Saiko yells.

"What?!"

"We have similar quirks! I can also use Overdrive!" he yelled and transformed. His arms began flaming a dark purple as his eyes turned pure red. Multiple chains came from his body and crow wings came out of his back. His teeth became serrated and his hair grew longer. Wind began to circle around him as well, along with a dark aura.

"Overdrive 10%" you yelled and began to transform.

You two began to duke it out but he was stronger. He might be more than 20% if he is around the same power as you. It won't be much but anything is better than nothing. You used a flashbang and ran over to Mina.

"Mina I need something," you say and copy her quirk. This seemed to snap her out of it, but you didn't have time to chat. You just need a little extra power to stop Saiko, and Mina's acid is perfect.

"Thanks, Mina, but please get out of here," you say and turn back to Saiko who recovered.

"Overdrive 15%!" you yell. All of your previous amps increased, but your platinum became slightly pink, and acid began to come out of your hands. Shadows began to dance around you, and your reaction time greatly increased. Acid also replaced your saliva, and you began to drool the acid. You also are hovering a bit.

"Really, only 15%? Underwhelm-" you then tackled him into the forest. You then began to burn him with acid.

"Overdrive! Platinum barrage!" you yell as you begin to stab into him. The chains blocked any lethal wounds. You then get ready for one final punch to his head, and you retract your right Wrist Blade, when you suddenly heard a voice.

"Ah Saiko, Y/N, here you two are," Kurogiri said.

"What Kurogiri?" you say, looking at him. Saiko used his chance to attack and suddenly you couldn't see anymore. Everything looked dark.

Third-person POV:

"Thanks, Kurogiri," Saiko said, holding a blue marble.

"You're welcome, Saiko. Glad to see my distraction worked. Let's take Y/N and regroup with the others," Kurogiri said and let Saiko quickly move to his comrades. Saiko then stopped as both Kirishima and Sato came out of the rift, unconscious.

"Let's leave em be. Shouldn't be a problem," Saiko says and then enters Kurogiri's warp gate.

Hello everyone, thanks for reading! I honestly didn't expect two chapters in a day, I thought I would've stopped by now, but I feel like I'm being possessed and forced to type. Anyway, Y/N has been captured by Saiko and Kurogiri. Also, don't worry about the other Dabi clone, Aizawa manages to stop him before he reached the students. Other than that, I ain't got much to say, peace!
