Mario was a contestant on Paths of Love, a reality dating show, who was eliminated when Shawn revealed that he already had a girlfriend back home, and Mario had a mental breakdown and physically attacked Shawn and Gus before smashing a vase over his head. He is portrayed by WWE wrestler Mike "The Miz" Mizanin.
Shawn and the Real GirlEdit
In "Shawn and the Real Girl", when Shawn and Gus go undercover to find out who put one of the contestants in a coma, Mario is their first prime suspect. This is due to how hot-headed he is, and how he said if anyone was here for the wrong reasons he'd kill them. While saying this, he stared directly at Shawn. Shawn and Gus searched the dorm room to find evidence to prove Mario guilty, but instead they find oil covered gloves in Danny's, the shy one's, bunk. However, while searching for clues Shawn sees a picture Mario brought of a girl on a motorcycle.
At the next Heart Ceremony, where the woman, Miranda, chooses who she wants to keep in the competition, it comes down to Mario and Danny, but right before Miranda chooses Mario, Shawn yells out that he has a girlfriend, so he and Gus can keep an eye on Danny. Mario freaks out and yells, "BROS BEFORE HOES!" before attacking Shawn and Gus. Miranda then chooses Danny and Mario smashes a vase over his own head.
Mario then appears on the Reunion Show, sitting next to Gus and Shawn.
