Doktor Frogg is one of the main characters and member of the League of Super Evil. While a mad scientist to the core, Frogg is the unluckiest man alive as he is always severely injured in some way or form. His mortal fear is Doomageddeon trying to eat him, which he does on several occasions. He seems to be the only member of L.O.S.E. who is genuinely evil, as Voltar is childish, and Red Menace is a gentle giant.
