THE F*CK IS A AVENGER?!!(My Hero Academia X Marvel Crossover Fanfic)

Young heroes?

3rd POV

He was in awe at the sight of the city. It looked really awesome and gleaming. He then blinked for a moment as he saw some figure flying towards him?? Wait-It was too late and the glass shattered and he was knocked down. He got up quickly and got some fiber glass on his arms but he tried to conjure up an explosion but a puff of smoke was all that came out. He turned the lamp on and on the ground was that spider hero he saw on the newspaper.

He also saw that his translator was crushed. Fuck. The possible hero got up and stared at him.

"Who are you!?"

Bakugou pointed at him self.

"Bakugou. You?"

The guy gave him a stare even though he couldn't see behind the mask.

"Spider-Man, and now that I think about it your that guy who helped Loki!"

Bakugou was suddenly stuck onto the wall by webs?

'Wait! Stop, you don't understand.'

All of course in japenese which had Spider-Man even more confused. Suddenly the others barged in.

"Yo, web head, you Alright? Didn't mean to send ya flying, woah, who's this dude?"
"Shut up bucket head, this guy is the one who helped Loki!"

He looked over the new bunch as he struggled a bit. A gold and green fighter like one from those retro games he played as a kid. A literal space cadet, some white tiger girl, and a guy with a suit and sunglasses.

'Let me go! I didn't want to!'

The tai fighter looked at me.

'I'm not a villain! Let me go!'

Bakugou was muffled by the web that hit his mouth.

"Shut up will ya! Jeez, we obviously can't understand you-"

The tai fighter's fist glowed and he set Bakugou free.

"Dude What the heck-"
"It seems you misread the situation friend, he is not foe but friend as well. 'I am sorry for my friend, he was doing what he thought best from the misunderstanding'."

Bakugou sighed and nodded. Then, the adults came in.

"Katsuki! Oh, what happened here?! Is that your translator! Damn it!"

Bakugou gave Tony an incredulous look.

'What the fuck took you so long?'

Tony asked Jarvis to translate.

"I was busy fixing the system so I temporarily turned the alarms off. Trust me, I would've been here sooner if it was on."

Bakugou sighed and suddenly felt all the fiber glass he had on his arms. He lifted his arms and spider-man winced.

"Sorry, in hindsight, I should've tried to talk this out more. Uh, let's get you to the infirmary."

With that he met the young heroes. As he was being patched up he was shocked beyond belief.

'You are telling me that you can become a hero that young here?'

Natasha nodded.

"It's quite different from what you know. If anything, you world is a bit more safer where it is accepted to have powers. In ours you are treated as a monster or freak."

Bakugou felt bad for all of those who were mistreated by this worlds standards.

"Hmm, I think you should spend some time learning to hold a proper conversation without the translator. I don't mind teaching you."

At this Bakugou got excited.

'That would be nice.'

He ended up spending a week of grueling lessons from Natasha and some help from Jarvis. By the end of the week he could fluently speak and read English. He would have to get use to it though since his sentences come out a bit slow.

"Thank you Natasha. 'Although I much prefer my native language'."

Natasha smiled and gave him some good news.

"Your healed enough to start some training. And about your powers, you should wait a few more days before you can use them. It's precaution and we don't need you to push yourself. Take this easily and don't push yourself over your limits. By the time your healthy you can start training with your powers and to start other stuff. Now the gym is open for you to use. So a simple warm up and a work out would be a great start."

With that, Natasha brought him over to their indoor gym. Katsuki wasn't as taken back.

"Huh, this is like size of my gym in dorms. Still nice."

He began some stretches and a few warm ups. He then started his work out and found himself a bit strained on what was the usual for him. He didn't push himself further since he didn't want to worry Natasha or the others. He finished his workout quickly and grabbed a towel to clean of his sweat. He huffed and was getting slightly bored with this work out. It wasn't the same as fighting things that move or dodging. Katsuki went over to the door and left.

He paused as he heard faint grunting. He followed the noise and was led to large doors.

"Young sir, what are you doing?"

Katsuki got used to Jarvis so he wasn't that shocked.

"I am wondering where noise coming from."

He saw a pad thing on the wall and he pressed it. The doors opened and he was in awe as he saw everyone fighting. They were all training against bots, that were honestly more better than UA's. He was still watching them all fight. He was distracted enough he didn't notice the bot flying towards him. Clint was the one to notice katsuki and the bot.

"KATSUKI!"

Katsuki saw the large bot heading his way and out of pure panic he tried using his quirk. A loud and big explosion sent the bot into pieces. Katsuki shook as his hands and body felt unused to his quirk. His hands were shaking and he saw they were bleeding a bit.

"Jarvis shut down training."

The bots all stopped at once and they crowded around him.

"Are you okay young warrior? That is a great power you have but-"
"I told you it was still dangerous to use it."

Natasha took his hands Clint handing her a roll of medical tape. She sighed as she wrapped his hands.

"You are lucky nothing worse happened."

Katsuki felt bad for worrying them more. After all, he's been nothing but something they have to look after.

"I am sorry, I was just curious to all the noise."

Steve sighed and nodded.

"Let's give him a pass, after all, he was just curious to what was going on in here. He has no way of knowing all this stuff Nat."

They nodded and he was let off the hook with a warning about his quirk usage.
