Killer is a very thoughtful person. He doesn’t feel many emotions, sympathy being one of them. He hates being belittled and is pretty negative. He loves bunnies. He has impressive knife skills and loves to make puns, jokes and pranks. He’s pretty chaotic and makes irritational decisions. He loves putting himself on a pedestal in a joking manner. He’s a part of a Undertale au group called bad guys, with dust and horror, the boss being nightmare. He likes to kill for fun if he doesn’t care of them
