Honorable Mention: Sen Dog (Cypress Hill)

Cypress Hill has had some crossover in the rock world (touring with everyone from Rage Against The Machine to even The Offspring, and even teaming up with Slash for a cover of “Paradise City”). And in season four, Sen Dog of the hip hop group portrayed a Mexican drug cartel soldier named Santo Rivera. It wasn’t a major role (only appearing in two episodes), but did feature the rapper testing out some guns (as seen in the image above).
