One For All (Villain!Deku AU)

[7]: Conflict

"Guess who has the same quirk as you now..?" Izuku was sitting on the windowsill, smiling innocently at Bakugou. "I'm not weaker than you anymore! Aren't you happy?" He put on a confused face, seeing that the person that he now hated looked shocked.

"You're lying." Bakugou scowled. "Now get over here so I can BLOW YOUR ASS OFF!!" He jumped out of the cot that he was resting in, and prepared to attack Izuku. Before he could, the green-haired boy had already sent an explosion in his direction. "But you can't even land a finger on me..!" His shrill voice pierced Bakugou's ears.

The explosion hit Bakugou, knocking him back against the wall. Izuku slid off the windowsill, entering the room. "At first, the idea of hurting you made me feel uncomfortable..." He fiddled around his mask for a moment. "...But when I thought about how you treated me all these years, I honestly can't-" His mind caved in on him again. Izuku's personalities began to shift. "ARE YOU BIPOLAR OR SOMETHING, DEKU?!" The ash-blonde got up from the ground and attacked Izuku.

"K-Kacchan... Please help me..." Izuku's tone and expression shifted as he saw his old 'friend' attack him. "Heh... Goodbye." The boy grabbed Bakugou's right fist and combined One For All with his new quirk, sending him through the wall. Sighing contently, Izuku walked outside of the nurse's office, making himself known to everyone. The alarm went off, and all students were evacuated. Before they could get out, he took a shortcut and stood in front of the emergency exit.

All the students stood there in shock as they slowly recognized Izuku. "Hey, aren't you that kid that went missing a couple months ago? Midoriya?" He heard someone ask. "That boy... is dead. I'm taking his place..!" Everyone ran away from him as they saw him charging up an explosion. "All heroes are just hypocrites... They never save." He fired two shots through the ceiling. His plan was to destroy the school that led to his pain and suffering. "These teachers call themselves pro heroes, when they never tried to save me in the first place..."

After destroying almost one-third of the school, he came face-to-face with All Might. "Young Midoriya. I'm deeply sorry that I couldn't save you-"

"Calling yourself a symbol of peace... when you're the main reason for all the villains." Izuku smiled lifelessly at the pro hero. "I was tortured. For FIVE MONTHS..!" The boy charged at All Might, both of his quirks activated. "It's all YOUR FAULT!!" Seeing that he had startled his ex-role model, Izuku went in for the attack. He combined an explosion with a Delaware Smash, injuring All Might. "Didn't you learn that you shouldn't get distracted in battle?!" Another punch was landed, hitting the hero's face.

At a quick speed, All Might dodged Izuku's next attack. "Heh... I still need more power to beat you... I'll take care of you later." The green-haired boy sent energy to his legs, and escaped All Might by jumping through the ceiling. 

"I'll destroy this whole school..!"

"S-Stop... Please... I don't want to do this..."

"People will realize how strong I am if I can show it to them... By destroying everything..!"

Izuku's mind spiraled into insanity as his thoughts clashed against one another.

"STOP RIGHT THERE, DEKU." Bakugou stood in front of Izuku, scowling. "W-Why... I'm..." Izuku covered his ears. "I'm... I'm sorry..!" His personalities switched around, and he debated whether he should fight Bakugou, or not. The green-haired boy ultimately decided to send an explosion at his classmate. The latter blocked the attack, and lunged at Izuku. "YOU FUCKING BASTARD... I'LL KILL YOU!!" Izuku jumped towards him. He wrapped a hand around Bakugou's neck, and slammed him against the wall; knocking all the air out of his lungs.

The ash-blonde squirmed, but Izuku's grip was too strong. "D-Deku, let me go-"

"W-Why..? Why should I, eh?! You never stopped harassing me when I ASKED YOU TO!!" Izuku's speed was enhanced, and Bakugou couldn't block any of the attacks that were directed at him. "I HATED IT..! I THOUGHT WE WERE BEST FRIENDS, KACCHAN!!" Izuku punched him in the stomach. After a couple more punches, he saw that Bakugou wasn't able to move, so he stopped attacking. 

"Honestly... I wanted to kill you..." Izuku's playful smile faded. "But there's just something holding me back... Disgusting." Looking outside, he saw cameras and news reporters swarming outside the U.A. campus. He grabbed Bakugou by the collar and jumped out of the building, showing himself to the world. 

"YOU SEE THIS?!" Izuku lifted up Bakugou's unconscious body. "That's going to happen to every person who gets in my way... And I WON'T HESITATE TO DO IT." He grabbed Bakugou's body, and threw it with full strength into the sky. Then, he looked towards the cameras, pointing at them. "YOU'RE NEXT..!"
