Very violent, rarely changing emotions, very stubborn, refuses to show any sort of weakness
Balthazar wasn't made for any particular purpose, just as an experiment to see if he would work. However, his programming was pretty flawed, which made his range of emotions limited. He lived with his creator, Toby, for the first two years of his life, but over time he started getting violent thoughts. At this point, his self control was a lot better than it is now, so he never acted on them. He soon became bored of Toby, and since he was illegally made he wasn't allowed to leave the house. Over time, this resulted in arguments and threats, mainly from Toby threatening to shut him down, and eventually led to Balthazar attacking him and leaving. Now, with a hatred for humans, he lives in a junkyard, and has started killing anyone he finds there.
