Rough Rider

Rough Rider was a member of the grave robbing gang led by Fedora, which recovered the Cross of Coronado from a Utah canyon in 1912. After Indiana Jones stole the Cross, Rough Rider chased Indy and fought him on the circus train. During the fight, Rough Rider and Half Breed followed Indy into the snake car and got momentarily trapped. Rough Rider used his pistol to unlock the train car door, and later drew his pistol on Indy after helping to hoist Indy out of the lion car.

Rough Rider later appeared at the Jones household when Fedora reclaimed the Cross with police assistance.
