(note: you are Killer in this story) Killer were the second in command of Nightmare the boss of the Bad Sanses. Killer's coworker were Horror, Dust, and Cross and also sometime Error who is a destoyer of AUs(Universes). Killer were an annoying and psychopatic skeleton yet he was important for the Bad Sanses (each members of the Bad Sanses are important for the Bad Sanses). Unfortunatly one day he died, something that wouldn't have been normaly possible since he had "determination" in his soul and a "save" in his Universe, that left the Bad Sanses shocked and even months after his death they are still unabble to accept it expecially Nightmare the boss of the Bad Sanses. Except that Killer is nit really dead but he became like a spirit... unluckly no one can see him until... the day where Nightmare was reading a book and then saw a spell that doesn't have any description and Nightmare was curious so he decided to spell the spell (no shit ?). that is the start of the story! add if u want.

Killer is skeleton, he has been control by the Chara of his Universe and he does many genocide and resets. but one time he finally free himself from the control of Chara and Nightmare help him by killing Chara. Now Nightmare ask to Killer if he wants to join the Bad Sanses. Killer is emotionless in his soul second phase, in his soul first phase he has emotions. Killer is a psycho, he always smile it is like a mask for him, he kills people, he is irritating, he looks dumb but he is genius.
