El Mustachio Grande looks like a classic wild west villain. He carries around a gun and wears ammunition around his torso. He has red hair and a red mustache. He wears a sombrero with red and yellow zig-zags. He has a gold tooth and stubble.
El Mustachio serves as the villain for this Island, he first appears in the Train Robbery game. In the Final Shootdown, after defeating the others he runs out exclaiming, "You'll never catch me, Marshal". You must hunt him down on your horse until he gets trapped behind the wall of a canyon and you lasso him. He later appears in the Diamond Plains Prison.
