He met Curly Bill when he joined the John Kinney Gang, rustling cattle and fighting against Billy the Kid's Regulators gang. Afterward, Pony rode with Curly Bill on wild escapades into Mexico as the Cowboys took shape. Now, as the criminal network is forming into more of an organized syndicate, Pony is looked upon as one of its legendary leaders. He's tough and rugged, yet he values the Cowboys as his family.
