Emil Eagle is a criminal mastermind from the universe of Disney comics. He is a wicked inventor and arch-rival of Gyro Gearloose, but while Gearloose is an altruistic soul who seeks no profit from his inventions (other than to make a living) and wishes to help others; Eagle is an ambitious thief who uses his technology to overcome the police and steal valuables. Also, despite being a capable inventor himself, he often steals Gyro’s inventions to use them for his own purposes. He is usually imprisoned at the end, but always manages to escape. Eagle has frequently allied himself with other villains, including the likes of Phantom Blot, Peg Leg Pete, Dr. Stigma, Mad Madam Mim, John D. Rockerduck or the Beagle Boys. His enemies have been no less diverse, as he has been defeated by Mickey Mouse, Goofy (usually as his Super Goof alter ego), Donald Duck, Uncle Scrooge, Feathery Duck, Chief O’Hara, and more often than not with the valuable help of Gyro Gearloose, who is quick to report to the authorities every time Emil Eagle steals his inventions for some criminal plan.
