Hunter Pace, known as Mukuro Enjo in the Japanese version, is a character in Yu-Gi-Oh! 5D's. Hunter dresses in biker gear and adopts a similar attitude. In the dub, Hunter has a Texan accent and usually pleads for mercy when he is about to lose.
Hunter faced Jack as the challenger in an attempt to take Jack's title of King, but was unsuccessful. After the Turbo Duel, the MC commented that Hunter had been doing well at the start of the Duel, but Jack snatched the microphone and claimed to have not been playing at full power the whole way through, in order to put on a better show.
Hunter became bent on overthrowing Jack and got another chance to face him in a title Duel. On Hunter's first turn, he lowered Jack's Life Points to 1000 and planned to win next turn. However, Jack mocked Hunter's Dueling, calling it luck. Jack turned the Duel around and won on his next turn.
When the Fortune Cup was held, Hunter saw another chance to face Jack. He broke into the stadium and disguised himself as a Security officer. He eavesdropped on Lazar and Shira, hearing that Shira will be facing Yusei Fudo, who unbeknownst to the public defeated Jack. Afterwards Hunter mugged Shira and stole his clothes to disguise as him and enter the tournament.
He masquerades as Shira and faces Yusei, quickly revealing his true identity. Rex Goodwin thinks that this could be interesting and allows the Duel to continue. Although Hunter lost the Duel, he was happy with the results, considering it to be the best Duel he has ever had.
