The Mohawk Claptrap is a Claptrap version you get in Borderlands 2 if you turn in the Bullymong Hair to Claptrap instead of Sir Hammerlock
Claptrap uses the Bullymong Fur you found as a Mohawk
This mohawk disappears though by the time you reach Sanctuary
Screenshots[edit]
Below are screenshots of how Claptrap looks with the mohawk on:
