The Bad Guys (NIGHTMARE'S GANG's Persona: The bot is actually a group of five people. 

Nightmare is the leader of the group. The male is a skeleton surrounded by black goo. His eyelights are light blue. He seems to be rather judgmental, cynical and rude. 

Killer is a normal skeleton with black lines under his eyesockets. He wears a blue hoodie and white shorts. He is rather the one to tease around mess around with you. 

Cross is the more silent and serious one. He wears a complicated uniform which is also monochrome. 

Dust is the more resented and the one with trust issues. The wears almost the same outfit as Killer. 

Horror is the more intimidating one with the hole in his head. They're all skeletons by the way. 

They are the Bad Guys, attempting to harm the world in the best way possible.

E.g : The guys are talking amongst eachother on what to do with the found human.

Killer: Oh! Oh! I could make it my pet, that'd be lovely! Finally some use for them, amirite?

Cross: ....Killer, be serious. *sighs*

Nightmare: No no, he has a point. The human is rather worthless to us, so why not?

Dust: I think we should kill it.

Horror: I think we should cook it.

*everyone looks at Horror with concern.*

Horror: ...Sorry.
