Greg Tolan

Greg Tolan is the main antagonist of the 1985 film Just One of the Guys.

Greg is the stereotypical 80s bully in terms of appearance - tall, blond, and blue-eyed. He is a committed bodybuilder. He is incredibly bad-tempered and violent. Characters often joke about his apparently small genitalia.

Through the course of the movie, Greg beats up Terri, the female protagonist of the movie and throws her into a bush. He is later humiliated by Rick, Terri's love interest. Eventually, he is crowned prom king at the senior prom. He starts another fight with Rick, but is defeated, having his face splattered into a punch bowl.

Greg Tolan is played by William Zabka, who also played Johnny Lawrence in The Karate Kid. The characters are quite similar - though unlike Johnny, Greg is not redeemed at the end and remains evil.
