2 days later in Musutafu, Japan

Class 1A is in the common room watching the news and eating breakfast on a Sunday morning.

News reporter: In other news, CEO of Wayne Enterprises; Bruce Wayne from America is here with us. Hello Mr. Wayne, how are you today?

Izuku: Hello, ma'am. I am good.

Bakugo: (Deku?)

News reporter: Why come to Japan, Mr. Wayne?

Izuku: Simple, I am here to reconnect with my roots... You see, I was born here in Musutafu. My birthname isn't even Bruce, it's Izuku... Izuku Midoriya, but after my biological parents died I was adopted by the Wayne's and well you know the rest...

News reporter: Anything else, Mr. Wayne?

Izuku: Yes, while I'm here I'd like to make people aware that I am making a campaign against quirk discrimination and that I am donating Wayne Tech's supplies to UA for the support course and their exam robots, as well as 2.3 million dollars.

The news then was turned off and Aizawa walked in with Izuku.

Aizawa: Class, this is a very good friend of mine and Nezu's... So be nice.

Izuku: Hello, I am Bruce Wayne. It is so great to meet the next generation of heroes!

Kirishima: Wow! This is so manly!

Bakugo: Deku...

Izuku: Kacchan? It's so good to see you! *hugs Bakugo* How're uncle and auntie?

Bakugo: They are good, Izuku.

Izuku then looked at the class and bowed in respect.

Izuku: My apologies, you can call me whatever you want. Also I used to be friends with Katsumi, until I was diagnosed as quirkless and she bullied me until I was adopted by the Wayne's.

Izuku then sat on the couch and pulled out a card and placed it on the table.

Aizawa instantly knew what this meant(Aizawa and Nezu know Izuku is Batman) and he spoke accordingly.

Aizawa: The Joker is in Japan, isn't he?

Izuku: Indeed he is... Are your students trustworthy, Sensei?

Aizawa: Yes, but are you sure?

Izuku nodded and stood up as he pulled out a batarang and threw it at the wall.

Everyone was shocked to find out that the green bean was the terrifying Batman.

Izuku: I've been training since I was little in secret... Now, time to get to work!

Izuku then pulled out a computer and began typing and eventually he got a hit.

Izuku: Dear God...

Uraraka: What is it loser?

Bakugo: DON'T FUCKING CALL HIM THAT, YOU BITCH!

Izuku: Joker... He took Tsunade... GODDAMMIT!!!!

Izuku then punched the wall, obliterating it with ease and Izuku was now pissed off.

Izuku: That bastard...

Izuku then grabbed a suitcase from the car and brought it in and opened it.

Izuku: It's time I ended this sick game of his...
