Boxer

Boxer is a character who appears in the Cartoon Network original series Ben 10.

Description
One of the Alpha Mutants created by Dr. Animo to be his servants, Boxer is part gorilla and part horse. He has the heavily-muscled upper body and arms of a gorilla, and the legs, hooves and head of a horse. Boxer's ape ancestry grants him a degree of superhuman strength.

History
Boxer was one of the Alpha Mutant guards sent to watch over the Accidental Mutants used as slave labour on Dr. Animo's farm, but was defeated and imprisoned when Ben Tennyson, in his Stinkfly form, convinced he oppressed Mutants to fight back against their captors.

Some time later Boxer, along with the other Alphas, were telepathically commanded by the alien Vilgax to attack both Ben and their former master, Dr. Animo. However, once again the child hero was able to defeat them and emerge victorious.
