Bill Savage appeared in the first issue of 2000 AD (1977) in the series Invasion! which depicted the conquest of Britain by the Volgan's People's Republic (an alternate version of the USSR which had replaced Communism with Fascism) in the (then) future year 1999. A truck driver from East London, he wasn't particularly political but after discovering his wife, son and daughter had died as collateral damage from a Volgan tank shell, he went out to kill any Volgans he could find. His successful extermination of a Volgan tank crew was spotted by Lieutenant Peter Silk, a member of the British resistance, and Savage was drafted in. Initially leading the Mad Dogs (with Lt. Silk as his 2nd in command) guerilla unit out of a secret base in the Isle of Dogs, Bill Savage became the most successful resistance agent. His flamboyant actions and brutal common sense turned the tide of many missions.
When the heir to the throne, Prince John, returned to Britain, Savage and Silk were involved in keeping him safe and attempting to smuggle him back to Canada. They succeeded, though Silk was killed by Volgan agents. Invasion! ended in prog 51 with Savage believing that, as the Volgan agents had murdered American citizens, the United States would cease being isolationist and would liberate Britain.
In 1979 Bill Savage returned to 2000 AD in Disaster 1990, a prequel to Invasion! showing Savage dealing with the consequences of a nuclear accident that causes the melting of the Arctic Ice Cap and a temporary rise of the coastline that floods southern England. It does not appear to be canonical with Savage.
