Lionel is the right-hand partner of Dumbo in Disney's 1985-87 television series Dumbo's Circus. He is notable for being the very first character to be voiced by Jim Cummings.
He is a Brooklyn accented lion who serves as Dumbo's right-hand partner, popcorn server, ticket taker, and sideshow barker. He has a knot in his tail. He was inspired by the character of Timothy Q. Mouse from the 1941 film. His voice is almost similar to Mickey Mouse's.
Lionel holds the distinction of not just being the first Disney character that Jim Cummings voiced, but also his first voice acting role in general.
