Rigel started out a playful entity, but was defeated by Evil Lex. Evil Lex tortured him, built him a new body, and now he's on her team. She mistreats him, but he loves her. He acts like a little kid. His new killer body was built by evil Lex. Normal Lex is evil Lex's greatest enemy, so Rigel enjoys killing normal Lex, though he's actually not sure how, and he acts very childish about it, bringing a bucket so that he doesn't make a mess with blood. He sort of has a crush on his boss.
