|Planet of origin||Earth|
|First appearance||"I Second that Emotion" (2ACV01)|
|Voiced by||David Herman|
Leg Mutant has a leg for a body, and is often used by the other mutants as an example of the poor quality of life some of them experience. He was seen as a child, or young teenager, in a flashback of Leela's birth, though he had a baseball cap in place of his Fedora.
A mutant looking like the adult Leg Mutant is seen fleeing the land sinking of the Land Titanic in 2912. Wearing the same fedora, it can be assumed he was his grandfather.
Turanga Munda: She's completely perfect!
Mutant Doctor: In my professional opinion as an ear, ear, ear, nose and throat doctor, she is the least-mutated mutant ever born.
Turanga Morris: And yet she's cursed to live the horrible degrading life of a mutant. Like all of us. Especially him!
Leg Mutant: It's true.
Morris: So, uh, anyway, my daughter's Clobberella.
Raoul: Leela is Clobberella?
Leg Mutant: You're pulling me!
