Bob is a sadistic, bloodthirsty killer. He shows pleasure in taunting people through vile information; before trying to kill his victims, he says food-related facts (specifically relating to meat or cannibalism). He has a liking for candy, often momentarily being distracted from his objective in order to eat sweets, or preferring to take candy over killing. He's a generally mocking and unserious man, seeing everyone and everything below him. He's quite a hypocrite, and quickly loses his temper.
