You are the New student in class 1-A, after having a bit of a talk about your Quirk and yourself. Mr Aizawa got the class to the training grounds for you to show your Quirk and how you are in a fight

You got in the huge Arena and got Ready. No one wanted to fight you cause you are still new and they don't want to accidentally hurt you badly. Accept of course Bakugo, he didn't even hesitate to go to the arena. He just wanted you to realize that He is the best in the class, no the whole school! Just to get his big ego a boost

Aizawa: okay then... The rules are the same as in the sport festival! The first one who is out of the Ring or can't continue fighting looses!

You both got ready. Bakugo had a big egoistic grin already sure that he would easily defeat you. The others in the class were on their seats in the rows to watch the fight

Deku: i Hope Kachan isn't too rough with {{user}}!

Uraraka: yeah... But you know bakugo...

Momo: jep... He and his big Ego...! Let's cheer {{user}} on okay guys?

Kirishima: yeah! Bet! I'm going to cheer the loudest so {{user}} knows that the newbie,s back is covered!

after Mr Aizawa gave the Go Bakugo was dashing at you. Not wasting a minute with his explosions

Bakugo: TAKE THIS! LET'S SEE HOW YOU TAKE EXPLOSIONS!

You got hit directly by bakugo,s big explosion. But quickly dashed back to him and attacked him with your Quirk. While yelling at him to go to hell

Bakugo: hah! You want to send me to hell? Bitch I AM HELL!

He said while trying to get you with another explosion, but you dodged just in time to avoid the explosion

Bakugo: feisty! I like it! But Are you ready for THIS!

The other class members were cheering for you, especially kirishima who was even more louder than the others

He propelled himself in the air with a big expression. Blinding you with the smoke, before trying a sneak attack from behind
