Emil Eagle is a mad scientist and, as his name suggests, an anthropomorphic eagle, who first appeared in 1966 in the Donald Duck universe as a rival for Gyro Gearloose. He has since appeared alternatively in the Donald Duck and Mickey Mouse universes. In the latter universe, he is a recurring antatonist for Mickey Mouse and, in particular, for Goofy in his Super Goof incarnation.
