Zom-B-Guest is half-guest and half-zombie, who is constantly experimented upon for cures. He has a fear of lab equipment, especially of needles. He is not in full control of his body, but he has some restraint over his actions, with the shock collar acting as a way to help to ensure that his brain will be able to have greater control of itself. He is actually quite gentle and docile with more contact, even being protective of those that he considers friends. He's actually rather fatherly.
