Barbara is a resident from Crashtown.

Biography
Barbara sends a letter to Yusei Fudo, requesting that he save his former friend Kalin Kesler. As Yusei arrives in Crashtown, he is challenged to a duel by three individuals. Barbara, however, stops the duel - stating that such a duel is prohibited by the town's rules. She then reveals to Yusei that she sent the letter requesting his help.

Outside, Barbara begins to explain to him about the town's horrific settlement. As they both observe as the sun is setting down, two rival gangs confront each other, one belonging to a guy named Malcolm, and the other one to Ramon. Barbara states that when the sun sets the two gangs officially duel.

Yusei then notices Kalin looking and acting different, to which that Barbara explains the reason for her wanting for Yusei to save Kalin. As she states that he has come to that town to die.

Yusei then learns that those who lose a duel in the town are forced to work in a mountain forever. Barbara then states that in order for Yusei to save his friend, he must defeat him in a duel, since it's the only way to be released from Ramon's group, at which time Yusei must take him back, before Kalin is taken into mountains.

After the duel ends, Yusei and Kalin ended up being double-crossed by Barbara, who actually was secret a member of Malcolm's gang. Still later, after Lotten's Turbo Duel with Yusei, Barbara changes loyalties again, and sides with Lotten, double-crossing Malcolm as well. It would seem at this point that Barbara is on no-one's side except her own, deciding to side with whoever she can benefit the most from.
