Oh, right, the baner. Forgot about him. I can't think of a Western equivalent. I guess the closest thing would be the Deputy? I don't know...
Deputy could be easily confused for the Sheriff, so maybe just a Cowboy/girl. As for the auto win, the Bandidos are trying to rob the bank, so I felt like that made sense.
Also, my phone spells it with a T for the Bandidos.
