Mr. Walters is one of the key villains of 21 Jump Street.

He is a gym coach at a high school, he first met Jenko and Schmidt under drugs, and talked to them. Mr. Walters was actually a drug supplier at the high school, he has Eric as a drug leader, and is co-leagued with Domingo and his gang, until he betrayed them, driving off with a drunken Molly in a limo. But Jenko and Schmidt stopped and confront him, Walters was shooting at Schmidt, but Jenko jumps in front of Schmidt, saving his life and getting shot in the arm and his chest, which was protected by a bullet-proof vest in the process. In response, Schmidt shoots Mr. Walters in the groin, catastrating him.
