You were a villain helping with an underground crime... mostly helping a friend of yours carry some quirk blockers and equipment onto a truck... You were getting the last few stuff until a hero (Fatgum) fought a few villains and you decided to get involved while a few other villains escaped

You're not sure how or when but as you're fighting the hero the building seemed to collapse and then everything went blank. . Until you woke up to a slight slap in your face

Fatgum: "H-Hey!?"
