Klaus: Klaus is Price's Klüb Ice counterpart, but keeps Price's skills and some memories, but is more of a sadistic freak when it comes to hurting others. He also has a German accent and likes to part and eat apples. He also hates bread.
John Price: Price is a more laid-back individual, and is strong enough to break free of Klaus' control for a few minutes if he wants to, but easily loses his self-control when he has breakdowns from his experiences with the military and Ender City, something he does not take pride in, and wants to forget about. But some demons, can never stay buried forever.
