Villain made from heroes

The USJ

When Izuku stepped out of the portal he was aside from Shigiraki, Kurogiri, and the giant Nomu guy watching the inside of what he knew as the USJ.

Upon his side, he knew that everyone here was criminals and basic thugs working through this as a normal job.

In front of him, the teen saw Kacchan right across the field of students and the heroes Thirteen and Eraserhead.

"Hello there, I am Kurogiri and we are the league of villains," As Kurogiri was introducing them Izuku was overwhelmed to see Kacchan there as a hero in training.

"Shame, All Might isn't here, oh well," as Tomura was talking Izuku saw Kacchan then turned to see EsaserHead rushing towards the thugs and neutralizing them.

"Kurogiri portal now," Without hesitation, Kurogiri saw what Midoriya was talking about and opened a portal engulfing Bakugo whole, and all the students were sent to separate locations.

Shigaraki turned to Izuku with glee and whispered into his ear, "good eyes, now take notes on these kids, quirks and all now will you."

Izuku understood now why Sensei sent him here so he nodded as a portal opened up for him and when he entered he landed in a random location overseeing a red and white-haired boy.

"Shoto Todoroki," the green teen looked at the young hero kid.

Watching him he began to take notes on what the boy could do and saw him use his right side to freeze most of the villains around him.

Izuku watched as he took notes but he saw that it was only his right side that he used, why not his left.

He questioned that wondering what reason he would have for doing that and watching for minutes led him to be distracted temporarily.

Quickly a shot of Ice rushed towards the green teen who quickly jumped far from the spot, nearly taking him out.

Izuku then looked at the hero in training who seemed to wait for him to attack.

The teen knew not to do much and thus needed to leave the spot soon.

Placing a marker on that question Izuku called Kurogiri to open another portal to a different location and as soon as a portal opened he rushed quickly before he was encased in the frozen ice.

The red and white-haired boy looked questioning who that was and his reason for watching him.

Once within a new area, the green teen turned then he saw three students, a blond boy, a nearly naked girl, and a punk rock-looking, girl.

Overseeing them he saw that they were surrounded by countless villains but they were planning something.

"Interesting, what are they thinking?" Deku wondered and as he neared them he could see something interesting, knowing about quirks what he saw next proved this theory.

The naked girl seemed to create a blanket out of her skin while the blond boy then electrocuted the villains around him.

Commencing with his quirk the green teen then jumped upward into the sky removing himself from the electric attack.

Izuku was glad to be up high but then he saw the boy be taken by one of the villains, showing him that this kid had drawbacks with his quirk.

Seeing what's next with the girls knowing that they could beat the remaining villains left him with a feeling that he saw enough, thus Izuku called for another portal to be opened.

Within the new portal, he entered he landed in a water zone seeing a purple boy pulling from his ball-shaped head spheres to the villains behind them as he was being dragged by the tongue of a frog girl.

Taking notes Izuku turned upward to see one of the balls being thrown in his direction which he managed to dodge with ease.

Izuku looked at where it was aimed from and thus saw how the frog girl and the purple guy moved far from the crime surrounded boat.

Seeing that they saw him he called for a portal and escaped into a battle with a red-haired kid and ...... Kacchan.

The two seem to have defeated all of the villains at which point they noticed him, "Hey, you were there with hand freak and mist freak!"

Kacchan then blasted himself at him where Izuku dodged and began to run as far away from him as possible.

Immediately, Izuku saw Kacchan running toward him, so he asked Kurogiri to portal him back.

When the portal opened returning to the main battle zone Izuku saw the giant bird man pinning Eraserhead down to the ground with the frog girl and purple boy from the boat there.

Taking a moment to regain his breath he believed himself off the edge only to turn and see Kacchan blasting himself onward with his quirk as well as being followed by the red-haired boy.

As Izuku panicked he yelled at Kurogiri, "Kurogiri, down now."

Kurogiri, confused by the suggestion ducked nearly avoiding Kacchan's Explosion and the red-haired boy's attack.

Knowing that Kacchan was trouble Izuku ran towards him using his power enhancement to kick him and then the red-haired boy away.

Izuku knew that this wasn't going to keep Kacchan down as he then saw him quickly get up so he pulled a knife from under his sleeve ready to attack.

Living with Kacchan for most of his life Izuku knew his attacks easily, being able to dodge every single blow with ease but the red-haired boy was more difficult.

He saw that his quirk allowed him to harden his skin so attacking him would be near impossible.

Just as Izuku planned a new strategy the unexpected occurred.

"I am Here!" All Might has arrived.

And his own blood began to boil.
