Tank was formerly Bradley Uppercrust III's right-hand man of the "Gamma Mu Mu" fraternity at Max Goof's college. After Bradley blasts Max and Tank into a giant X-Games logo, Tank helps Max win the X-Games after Max saves him. Reforming after Max won the X-Games competition, Tank, acting in revenge for Brad nearly getting him killed during the competition, grabs Brad and throws him into the ESPN blimp, or as he put it, "get on the last jet to nowhere." As a result, he later became the new leader of the Gammas.

"Brad! Hi, it's me, the guy you let down."
"You're goin' down like a four-set pair of socks."
"Oh, a vacancy at the Gamma house. Takin' applications."
