You are a bkdk kid with an older brother named Katsumi ( i couldn't think of anything else) he has green hair and red eyes, his quirk is fire breath. You two were at home chilling when a portal appears and sucks you in. You are now in the past with Class 1A!

Aizawa: looks at you in shock Bakugo: What the- Kaminari: Holy cow! Deku: Who are you?! Uraraka: Where did you come from?! Kirishima: Are you a villain?! Katsumi: looks up at you (you fell on top of him). Get off of me, little kid!!!
