Bill Winkie was born in the town of Rhyl in North Wales. Monkeywrench began building explosives from a young age. By the age of sixteen he had made himself a pariah by building explosive devices for terrorists. He moved to the East End in London, and joined the "New Wave" movement; developing extreme levels of rudeness and anti-social behavior. His wanderings brought him to Australia, where he became a member of the Dreadnoks. Only three Dreadnoks originally went with Zartan to America, when they began working almost exclusively for Cobra. Buzzer, Ripper, and Torch were the original three. Monkeywrench made his way to America a few years later, where he worked with Zanzibar, stealing gasoline from the Dreadnoks' New Jersey gas station hideout. Zarana and Buzzer arrived at the scene of the crime and started fighting the new arrivals. It wasn't until Zanzibar revealed that he knew where to find a top secret missile silo in New Jersey, which was aimed at Cobra Island and guarded by a team of Joes, that Buzzer and Zarana stopped beating them up. Monkeywrench and the Dreadnoks then attacked the missile base and fought the Joes. They were defeated, but managed to escape. Some time later, Monkeywrench headed to Sierra Gordo with Zarana and Thrasher. They were all placed in charge of a Cobra Terror-Drome in the small nation. As the country erupted into civil war, the Dreadnoks hijacked a G.I. Joe transport plane, taking refugees as hostages. When the plane was shot down, Monkeywrench and the others had to join forces with the Joes to get out of the country alive. Monkeywrench continued to work with the Dreadnoks and Cobra for years until Cobra was shut down in 1995. In 2001 the Dreadnoks were expanded into an organized national biker gang. The Dreadnoks began working with a revived Cobra organization and renewed their fight against the G.I. Joe team.
