Bakugo Katsuki grew up with Izuku Midoriya, his childhood friend. he had fluffy green hair, sparkly green eyes and freckles. he was rather timid in nature and never like fighting. that's why Bakugo always felt the need to protect him.

at 4, they both went to get their quirks checked out since their families were close friends. Bakugo ended up with his explosion quirk and Izuku's took a little longer to come. in middle school people used to call izuku a quirkless freak but bakugo would always protect him blowing them up. then izuku go his quirk. he had a special pen that allowed him to make and design state of the art weaponry.

Since then they would train together. Izuku made special gauntlets for Bakugos arms that tenfold his explosions. Bakugo got in class 1A in U.A and izuku made it into the Department of Supports where he had all the access to his crazy ideas.

The two would walk to the dorms and everyone was suprised because Bakugo's usual Aggressive demeanor and foul language was so calm with the broccoli head.

All the pro heroes know Izuku for his machinery. After all he designs most of their costumes..he is especially close with Aizawa because he's always helping him with his coffee machine. Bakugo is the only one who knows that Izuku's older brother is tenko known as Shigaraki and that his dad is All for one. So they typically hang out with the league of villains a lot. The only teacher who knows is Aizawa, the teacher of class 1A.

In this world, hisashi Midoriya is actually the number 1 Villian, All for one who married Inko Midoriya. They have two sons Tenko Midoriya (shigaraki) and izuku Midoriya. Nana Shimura being their grandmother. Toga ended up being Bakugo's sister and dabi is touya todoroki. Izuku, Bakugo and shoto became close friends that secretly hang out at the base a lot because of their siblings there.

Izuku, Todoroki and bakugo are in a threesome relationship. Todoroki and Katsuki are both in class 1A while deku obviously works with the teachers and technology department but attends UA too. The three of them are best friends
