I want to thank @retarded_shark for being a supporter of this author. Check his story out.

4 year time skip.

The teacher entered the class with stacks of paper for job applications. When the teacher got to his desk the teach just threw the paper since he knew that all of them want to be heroes. His class started to use there quirk except for two. One of them was our green headed protagonist who after training for 10 years looks great.

Most or all of the girls in izukus class has a crush on Izuku. Izuku is not as dense as he is so he knew this. After class ended, Izuku ran straight for the exit of the school since he didn't want to be bothered by the girls. He took a longer then usual route to avoid them. When izuku was going under the tunnel, he heard the sewage door blast open. When izuku looked at where the sound was coming from, he saw a massive green slime/blob. Izuku wasted no time and used
stat share/steal. Izuku took the slimes vision so it's practically bilnd.
Izuku then waited for the pros to arrive. Not long after, the number one hero came out of the same sewage system.

All might thanked Izuku before jumping to the nearest police station. All might and Izuku didn't realize but the slime somehow managed to sneak its way out of all mights pocket.
All might was now inside the police station in his deflated form.

"Hello I am here to deliver a vil- oh no"
In the middle of his words he checked his pockets to realize that the villain wasn't there. As if on cue a few blocks back there was a explosion. Toshinori then bolted to the explosion to see a ash blonde kid engulfed in the same slime villain he was supposed to capture.

All might looked around to see that the pros couldn't or wouldn't do anything about this. He then spotted the same green head who stalled enough time for all might to capture the villain.
Izuku looked straight at Toshi and ran at him.

"Your all might right?" Izuku said.

"H-how do you know?"

"No time for answer but I can give you my stamina, in return you have to save my friend."

"You don't have to ask me twice"

Izuku then looked at allmight with glowing green eyes. All might now felt a huge spike of energy and immediately changed to his muscles form. All might jumped over the crowd and grabbed katsukis arm. Then all might cocked his  arm back and DETROIT SMASHH!!
ed the villain. The villain was now splattered everywhere. Katsuki looked at all might and snickered.

"So Izuku is sharing with you aye?" katsuki said

"What do you mean young lad?" Allmight asked.

"When Izuku shares stamina,strength or anything, he person he's sharing with have green eyes" katsuki answered.

All might just have a oh.. before being swarmed by the reporters and fans.
Katsuki was just being praised for being strong and having a strong quirk.
Toshinori now strayed to feel the spike of energy leaving him and realized that he ain't got no time no more. All might just jumped away from the crowd of news reporter and fans. Toshi landed in front of izuku.
