Igor Fritz Radev was the hunchbacked assistant of Victor Frankenstein. He turned against his master after hearing him call his best assistant ever.

Trivia

 * Grant Moninger voices Igor with an imitation of the voice of actor Peter Lorre, who played a hunchback in the German film Der weiße Dämon. The voice may have also been inspired by Allen Swift's Lorre impersonation as Igor in the animated film Mad Mad Mad Monsters.
 * Igor's middle name of Fritz is a nod to the archetype's original incarnation in the 1931 Frankenstein film.
