Peter Nash Lupus Jr. (born June 17, 1932) is an American bodybuilder and actor. He is best known for his role as Willy Armitage on the television series Mission: Impossible (1966–73), as well as his appearances in several Italian peplum films under the stage name Rock Stevens.

Actor
Lupus was one of many bodybuilders who followed Steve Reeves into the Italian "sword and sandal" films of the 1960s, occasionally credited as Rock Stevens for such films as Hercules and the Tyrants of Babylon (1964), Challenge of the Gladiator (1965) and Muscle Beach Party (1964) where he starred as "Mr. Galaxy" Flex Martian. Armitage was the Impossible Missions Force's muscle man, and featured in nearly all episodes of the series. The character of Willy Armitage was the strong, silent type, usually with very little dialogue. Late in the show's run, during season five, the producers decided that his character was superfluous and he was dropped to recurring status, appearing in a little over half of that season's episodes. Outcry from fans and lack of success in finding a replacement for his character — originally replaced by Sam Elliott — resulted in his return to regular status the following season and to his getting a greater role in the stories, often assuming disguises as a convict or a thug. Only Bob Johnson and Greg Morris sustained regular roles through the show's entire run.
Lupus's other television work included a guest spot as Tarzan on Jack Benny's television show, a boxer with a glass jaw on The Joey Bishop Show, a caveman on an episode of Fantasy Island, and the recurring role of Detective Norberg on the short-lived sitcom Police Squad!
Playgirl pinup Lupus was one of the first well-known male actors to pose with full frontal nudity for Playgirl magazine, in April 1974. Photographs of Lupus appeared in a number of issues. Before this, he was hired by the United States Air Force to appear in a series of commercials playing the role of Superman (with the permission of what is now DC Comics). He appeared for many months until the Playgirl pictorial was published.
Personal life Lupus and his wife, Sharon, have a son, Peter Nash Lupus III, who is also an actor.
On July 19, 2007, at age 75, Lupus set a world weightlifting endurance record by lifting over the course of 24 minutes, 50 seconds at the Spectrum Club in El Segundo, California. This topped the record Lupus set five years earlier in celebration of his 70th birthday of in 27 minutes.

As a locksmith in the early ‘80s, Lupus couldn’t buff a key to save his life.
