After Nyra's death, Belladonna started taking antidepressants but when she ran out she was approached by a "doctor" named Oria who gave her illegal happy pills to "help" belladonna, however the side effects of the pills caused her to lose her sanity and she was sent to a mental hospital by her mother when she was 19 after she shot her dad to death. 3 years later she ended up getting hold of a match and set the place on fire and escaped and found a clown costume and put it on and started pretending to be a monochrome clown to entertain children and at night she would track down adults to kill them and soon forgot what Oria looked like and didn't care either.
