I'm Weak, But Tougher Than Iron (A My Hero Academia Fanfic)

Finale-Baptism by Fire

Izuku looked at the outstretched hand. Contemplating on whether he should take it or not was not something that would be done. "Hisashi...will you really leave everyone alone if I join you?" Izuku asked, he needed some clarification before he enacted his already thought out decision.

"Of course. I would never betray my son," he gestured for him to take his hand again, "now come, take my hand." Izuku looked his father in the eye, the man's hair was whipping around with the wind that was getting stronger. He wanted to say no and die with dignity, but if it was to protect his friends and family, then he would do anything. Izuku's right hand opened, revealing the fleshy contents beneath it, he had completely forgotten that it was this broken. Hisashi furrowed his brow before taking his son's hand, within a few moments it healed back up to normal, but it had caused Izuku to writhe on the ground in pain. "I may love you like a father's supposed to, but I won't tolerate your belligerent disrespect towards me. I'm also taking back what was originally mine until you behave and follow my every whim."

Izuku looked up from the ground at his father as he began to control the wind around them. He wanted to believe that something like this wouldn't happen, but he was obviously wrong. Which is why his suit began to go back to what it was. It covered his entire body once again. As he laid on the ground, he noticed that his suit's power storage was going up. in about three seconds it jumped up to 30%, which was enough to fight for about forty minutes. But he believed that he could have this over in ten if he forced another chest beam out of himself. Which is why he shot a beam of energy directly at his father. "I do not feel sorry for tricking you like this then," Izuku fired up the boosters in his hand and was propelled away from his father. He began to fly in the sky when he got far enough away. Another blast was shot from his hand, but a tentacle coming from his father stopped it from coming closer to him.

"So you dare refuse my offer? There could've been peace between us, but you would squander it that easily?" His father hung his head in shame, a circular dark area appeared from behind him. "I'll just have to correct that, I suppose." Just like earlier with Katsuki, tentacles began to pour out of the shadow. But Izuku was somewhat prepared for this, he brought his hands together and faced his palms towards the tentacles. A green circle of energy blocked every tentacle that came at him heads on. His power supply had been drained down to 20% after twelve seconds of keeping it up. But because of those twelve seconds, he observed something about the tentacles. As soon as the head of them were destroyed by the high energy, they would retreat back into the darkness. It wasn't until they all stopped coming at him that the darkness behind Hisashi disappeared. It was then that he dropped his shield and began his counterattack.

He was obviously outmatched by the abyssal assault that Hisashi had, but it obviously had some sort of cooldown before it came back. Which is why he flew directly towards Hisashi. His power level rose up to 21% before falling down to 19% as he continuously released two energy beams at Hisashi. With his entire arsenal, he easily had something that could block Izuku's attack, which is why there was a piece of the earth covering Hisashi from Izuku's sight. When he tore through to the other side of the slab of dirt and stone, he realized that Hisashi was gone. He quickly turned around mid air to see a fist of stone bore down into him. Some blood was spattered against his visor as the fist caused some of the metal of his suit to stab his stomach. "You are as insolent of a whelp as Katsuki was," Hisashi's face was taut, anger was consuming him. "But at least you put up more of a fight!" Another punch landed on Izuku's face, cracking his visor and making Izuku's vision show two versions of Hisashi's chin. But this is what Izuku wanted, so he wrapped his arms around his father and hugged him tightly.

"I've won, Hisashi," Izuku's chest lit up as his power levels began to drain, but they stopped when he heard Mei on his left. His focus was broken as he yelled at her to leave, which allowed Hisashi to break free from Izuku's grasp. This was done by stabbing him in the stomach, causing him to loosen his hold. "Get away from here," he weakly uttered, blood starting to come from his stomach. Izuku grabbed Hisashi's ankle before he could take two steps towards Mei. "Duck...Mei." Within a second his power levels were drained to zero and his chest beam fired off, consuming Hisashi and half of the U.A building within it. It fired for four seconds, sapping energy directly from his body as it destroyed everything within it's reach. He fell onto his back and passed out, his energy having been completely drained.
