Little is known of the origin of the mutant known as Leech. He was presumably abandoned by human parents and discovered by the mutant known as Caliban. Caliban took the young Leech with him into the network of tunnels known as the "Alley" running beneath Manhattan which housed the mutant outcasts called Morlocks. He is now a member of the mutant team Generation X.
