Izuku's body lit up. His hair glowed bluish green and stood on end. "One For All..."
Promethys focused a powerful blast of several combined Quirks forward in his direction.
"100%!" He shouted and crossed his arms, taking the brunt of the blast as everything around him started to crack and crumble into dust.
Everyone ran away from the powerful attack.
Izuku's costume tore down to his shoulders, his legs tore through his leg guards.
"St. Louis SMASH!" He swung his leg around, deflecting the energy blast with a gust of wind that broke the sound barrier there on the ground, sending the blast back and hitting Promethys.
Izuku then launched forward to punch the towering villain with a Detroit Smash.
Every tattoo in Promethys' body glowed brightly. With reflexes as fast as Hansuke's Chronospeed, he grabbed Izuku's fist and folded it down, sending the hero to the ground on his knees.
"Look into my eyes." Promethys hissed, lifting Izuku up enough to make eye contact.
Using a mind-reading Quirk, he accessed the hero's memories.
"I'm sorry Izuku... I wish things were different..."
"One For All. A sacred torch passed down..."
"I have to jump back...into his loving arms!..."
"If I can't save those two then I can't call myself a hero!..."
"Congratulations, Deku. You're a pro-hero now..."
"From this day on, I promise to always stand by you as your wife..."
"Make that power your own so we can have a proper fight!..."
Izuku headbutted the villain, causing him to step back while still holding on.
"I see now." Promethys whispered.
"No you don't!" Izuku thrashed around.
"I can't take One For All because it was never yours... I wish I knew that sooner. I will just have to kill you."
Izuku's eyes glowed brightly.
"Then I will kill everyone you love. Your wife, your daughter, your mother, your friends. Here today they will all-"
"-STATES OF SMMAAAAAASH!"
Izuku's fist uppercutted through Promethys' large elongated chin, sending them both into the sky.
The entire time, Izuku kept his fist planted on the villain's head as they flew through the air.
"No matter what it takes, I will defeat you!" Izuku strained.
"N-N-No!" Promethys grabbed his fist, his flesh melting off his body as he did so.
The crowd of retreating Loyalists and standing heroes and students watched as the two plummeted to the earth, smashing right into the school grounds, shattering the energy barrier like glass.
As the dust cleared, Hansuke ran to the crater in the middle of the grounds.
Heroes and people backed away as the first one to stand was Promethys.
"This hero seems to get...stronger each time I fight him." He groaned to himself. "I need a Quirk that will destroy his."
Hansuke grabbed Inko Midoriya and Eri and pulled them to the main gate. "We gotta get you out of here!"
Promethys charged through the crowd and punched Hansuke down on his stomach.
He then turned to the middle aged woman and the little girl.
"You must be Mrs. Midoriya. And you must be Eri." He taunted.
Eri hid behind Izuku's mother's leg.
"GET AWAY FROM THEM!" Izuku shouted.
"Excuse me for one more second." Promethys then jumped up and blasted the crater that Izuku attempted to crawl out of with a laser beam coming out of his mouth.
"This...is...madness..." Hansuke groaned.
"HANSUKE!" Izuku choked out.
Promethys hovered over the school staring down at the crater below with Izuku's body.
Without thinking, Hansuke activated his Quirk and reappeared by the hero's side, sliding down the slope of the crater and cutting his hand on a piece of rubble.
Izuku was very physically beaten, bleeding everywhere, from his head, nose, and mouth.
"He broke my legs..." He coughed.
Hansuke began to tear up.
Meanwhile, Katsuki blasted into the air and unleashed everything he had on to the villain.
Promethys formed a bubble of protection around his body. Katsuki rushed him again and blasted right through it, colliding with the monster in the sky.
"Hansuke... I promised everyone...when I became a hero...I would not waste any part of me to save them all..."
The boy grabbed his hero's bleeding hand.
"There's something I need you to do... With One For All, your Quirk will become amplified to even greater potential..." Izuku said weakly.
Hansuke immediately shook his head. "No! Only you have that power. You're the hero! You can do it!"
"He's broken so much of me that will not be fixed before he destroys everything... Please..."
The young Hispanic-Japanese boy started to cry. "I could never be half the hero you are..."
"Use this power... Save everyone..." Izuku pleaded.
Promethys and Katsuki rammed into each other again. But then, Promethys' body grew spikes everywhere as he hit the explosive hero, stabbing him in multiple places over his body.
"Agh!" He yelled out. "B-Bastard!"
Promethys pulled him off the spikes and threw his body down to the earth.
Katsuki's body landed hard, cracking the ground beneath him. Then Promethys landed on top of him with a sickening crunch.
"This...isn't...over..." Katsuki breathed.
Hansuke gripped Izuku's hand tighter.
"Go, Hansuke. The power now flows in you..." Izuku said.
Hansuke looked down at their hands. His hand which was cut, holding on to Izuku's bloodied hand.
"Wh-What?" The boy felt something spark inside of him.
Promethys looked around the crowd. Several heroes charged him but quickly fell to his many Quirk attacks.
Young Kota appeared and blasted him with jets of water, only for the villain to swat him aside.
Eri and Inko started to run away until Ochako caught up to them. "Where's Izuku?!" She asked.
Promethys sensed the power growing, and turned around, only for Hansuke's fist to meet his face.
Before he could recover, Hansuke disappeared and reappeared behind him, punching him again with the same fist.
The villain kept falling every opposite way, only to be met with Hansuke's fist once again before disappearing into his plane of time.
Ochako ran to Izuku's body in the crater and scooped him up in her arms.
"Chako-chan..." Izuku managed a smile.
"It's gone... I gave it to Hansuke..." He said softly.
Ochako teared up and hugged him closer. "You did it... You did it, Izuku."
"Hansuke is our only hope now..." He said closing his eyes.
Eri and Inko ran down and joined them in holding Izuku.
Promethys snapped his fingers up over his head and entered Hansuke's plane. "You stupid boy! I have your Quirk too!"
"Not like this." Hansuke said. "This ends now."
"I agree." Promethys hissed and charged the boy.
As they clashed, everything around them shattered.
Hansuke and Promethys held on to each other as time not only seemed to freeze around them, but everything began to turn backwards. One For All was coursing through his veins, giving him greater strength over time itself.
"What is this?" Promethys asked.
"Time to fix everything you broke." Hansuke said with his eyes glowing brightly.
The ground disappeared beneath their feet. They both felt as if they were in a giant vacuum tunnel. Everything in their bodies pulling themselves apart yet they were still held together.
"FREE ME! STOP!" Promethys roared.
Hansuke felt his bones shatter. Not just his arms from punching, but every inch of his body, no, every atom in his body being ripped apart.
Then he closed his eyes and snapped his fingers.
