When nighttime came the heroes had prepared what they called a super awesome test of courage, which was basically like a haunted forest they had to walk through in a big circle to get scared by the students of the other class, class 1-B.
Everyone was excited and ran around, showing that they could barely wait, but izuku had been devious.
He asked his father to commence the attack during a test of courage, because at least then his friends would be away from the camp and wouldn't throw themselves headfirst into the battle that was about to begin.
However, izuku hadn't taken account of the fact that Katsuki left to do the test before the attack, meaning they would be fighting in the forest, still, izuku hoped that it would be fine.
So even when he saw smoke in the distance, and his legs began to shake with worry and anticipation he let himself believe that things would be fine.
"Where's Kota!?"
izuku spun around to see Mandalay, her face filled with worry.
Izuku's eyes widened as he looked towards the tree lines that led to the boy's hiding spot. It was already late, so late that izuku had thought that he would have gone home and been asleep, but if he wasn't...
He had to go get him.
He didn't need to see what was about to happen, so without a second thought, he set into a sprint, making the mistake of telling nobody where he was going.
He ran as fast as his two legs could carry him and when he saw the cliff he shouted.
"Kota, come here! It's dangerous out here!"
"Help!"
Izuku's eyes widened as he caught sight of the huge man standing with Kota held off of the ground, being held by the front of his shirt.
"Let go of him!" Izuku shouted.
He knew the man as Muscular.
He had never met him but his father had told him about everyone that would help carry this mission out, and this brute of a man with a quirk to match was one of them.
"Huh? Oh, it's the Boss's kid..." muscular caught sight of izuku and spilled the secret like it was nothing.
It made izuku stumble back as if he'd been hit.
'It will be out today anyway, so what does it matter?...'
Izuku looked up with a fire in his eyes.
"I told you to let go of him!" He shouted and then used his quirk to pull the child towards him and affectively ripping him from the villain's grip.
"Oh?...there might be something you don't understand kid, but nobody tells me what to do"
"Then why are you here?!"
"Why? HA! Because it'll allow me to get a few kills in. I'm here because I want to"
"You're not allowed to kill anyone here!"
The villain cracked his neck and then took his eye out to replace it with another more menacing-looking one.
"I don't care if you're the Boss's son, ill need to teach you a lesson, and after you ill kill that boy like I did his parents"
Izuku's eyes widened and looked to see Kota frozen in fear.
There was no doubt that he recognized the villain.
"Kota, it'll be fine...I'm gonna protect you"
"Protect him? You're just a villain"
"No!" Izuku shouted and then use his quirk on the man pushing him into the cliffside and kept on pushing, hoping to crush him.
"Until the end of today, I'm still Deku, the hero in training!"
"Then...allow me to give you a death worthy of one!" Muscular shouted as pure muscles sprouted from his kin and formed thick layers on his arms.
His quirk was strong and it had made him believe he was invincible, so much so that he didn't even worry about the consequences o killing all for one's son.
He had escaped consequences so long that he probably didn't think they concerned him anymore.
Pushing against the force of Izuku's quirk the pressure became too much and he found himself losing the grip on the villain, and then in the next second, he was in front of him.
It was as if everything was going in slow motion when the villain raised his arm to punch izuku, planning to crush his bones and then kill him, but izuku wouldn't let it end that way.
He couldn't stop the blow from coming but he could make it a little less fatal.
Next to him was a rock that he was able to quickly get in front of him, using telekinesis, and just as he had hoped would happen muscular's fist first connected with the rock, then broke through it and hit izuku.
It hurt a lot, and izuku felt like he was gonna throw up, but he was fine.
He could still move.
He could still fight.
He could still protect Kota.
But what izuku had forgotten in the few moments when adrenaline overwhelmed all other senses was that while he had been able to stop a maybe fatal attack, it didn't mean that Muscular had been stopped. No, he was still looming over him.
"Nice reflexes, but can you do it again!?" He raised his fist and this time his lunch connected with Izuku's side as he just barely managed to turn.
The force of the blow made izuku get a metallic taste in his mouth as he was also almost flying off the side of the cliff.
Now he was laying on the edge, unable to get up fast enough, but then he, along with Muscular was doused in cold water.
"What the-...water?"
"Stop it! No more! Just let him be!"
Izuku felt tears in his eyes when he realized who his savior was.
Kota, the boy that hated quirks and heroes had just used his quirk to save him, to try to stop Muscular from landing the final hit, but unfortunately it had made Muscular focus back on him.
"Don't worry kid, I haven't forgotten about you" the villain grinned. "You know what? You can't even move, so what could be better than forcing you to watch this kid dying, knowing you were so close"
"Don't...don't you dare hurt Kota!" Izuku shouted, his voice breaking as he watched the child's face morph into unspeakable terror, and with Muscular not heeding his words and instead of going towards the boy, one step after the other izuku truly thought that he had failed.
Kota was gonna die, because of him.
"Don't!"
Izuku didn't know what happened at that moment, but he suddenly felt very cold, and then every tiny rock around him started to drift off of the ground.
Even Musclular stopped to look down the small pebbles.
"Is this your last attempt to stop me? To put a stone in my shoe?" The villain mocked, but then suddenly every last one of these rocks fell to the ground.
Izuku didn't understand what was happening, but then the villain almost stumbled.
"What the..."
Again and again.
Muscular didn't seem to keep his balance as if he was continuously being pushed.
And then chaos.
Izuku suddenly screamed in pain and as he did everything that could be lifted except for the two other people with him lifted off of the ground and began to fly around, circling Izuku.
It was like his body was tearing apart, and he was getting so tired.
"Kota! Run!" Izuku screamed.
He didn't know what was about to happen, but he had a bad feeling.
The boy didn't hesitate and began to run, but Muscular, however, was excited to see Izuku's true power, as if he'd been waiting for a worthy opponent, but when izuku saw Kota run he felt relieved, and without even knowing that he had restraint he let them go and every last stone and rubble was pushed out away from him in a giant explosion.
It tore and pierced through the villain that had no time to use his quirk in defense, and with the last scream izuku fell unconscious, not knowing if the villain was still able to kill him as he did, but no, Muscular was too injured, he was unconscious as well.

Ah yes, powers going out of control, one fo my favorite tropes.
Don't worry it will be explained in the future
