Nero

Nero is a robotic wolf/dog with the soul of a child. His creator is Biov Koffman which he always refers with his childish voice as Mother. When he kills someone he believes they are just sleeping because that is what mother has told him. When he is not around mother he acts as a playful dog and is very friendly to strangers (he only kills if Mother tells him.) If anybody that has psionic abilities is around him, they will hear static in their mind because Biov had program that and a nullifier program that just nullifies power that were known to be in the Koffman family because Biov always believes there are always people out to get her, even in her own family and she is afraid of what had happen to her husband and her son will happen again. Because of this she believes that most people are evil and that if people were made into robots the evil will be gone. Because of this ability, all Koffman usually try to avoid Nero. Nero lives with his Biov at NeroTeck which can only be entered by certain doors in different dimensions and the buildings windows only show the different dimension which the entrance will open to. No one but Nero, Hela, Lewis, Aten, and herself know where the entrance to this place.
And yes those are saw blades that are his teeth.

More will be add to the backgound when I add in this creature's creator, Biov Koffman.
