Raymond Tango is a self-proclaimed "worse cop" in the 1989 hit movie Tango & Cash.

He was portrayed by Sylvester Stallone.

It's a classic case of police brutality glorified. Though he is the hero of this movie, it's the nature of his acts and his enjoyment of it that earns him a villain status. When they take Requin, one of Yves Perret's henchman, and interrogate, Tango has a plan B that is more sadistic than Cash's plan. Whether Cash can be described as a villain is at question right now (the very fact that he fooled Requin into thinking he was gonna save him from Tango) might very well. Tango decides to put a bomb on Requin's mouth to blow him up, and he sadistically enjoys trying to hurt him. The only thing stopping him is that Requin wants to talk. But while he's blowing him up he enjoys it.

You're supposed to root for Tango (I get that), but he's still a villain in the definition of the term. He's a sadist. He's no better than Requin or Perret.
