Monkeywrench is a fictional character from the G.I. Joe: A Real American Hero toyline, comic books and cartoon series of the 1980s. He is affiliated with Cobra as one of the Dreadnoks and debuted in 1986.
His real name is Bill Winkie. Monkeywrench was born in Rhyl, North Wales.
Monkeywrench was born on Guy Fawkes Day, which in Britain commemorates the foiling of the Gunpowder Plot. As a youth, he built explosive devices for terrorists, and had made himself a pariah in his hometown by age sixteen. He drifted to London's East End to take part in a "new wave" movement, developing rudeness and crude anti-social behavior. His wandering eventually brought him to Australia, where he joined the Dreadnoks.
