Bio: McCarthy was born in Boston, MA and spent three years as a taxi driver before deciding on a safer line of work -- the Army. Blocker was qualified to drive every wheeled vehicle in the Army, and served at the Aberdeen Proving Grounds where he was the test driver for a half dozen prototype vehicles. He was later assigned to Battle Force 2000 where he drove the team's Eliminator vehicle.
Battle Force 2000 was involved in the Battle of Benzheen against Cobra, along with almost the entire G.I. Joe team. While they were maneuvering near huge oil storage tanks, the oil was ignited by enemy fire. The explosion that followed took the lives of every member of Battle Force 2000 but Dodger. The team's deceased members and the other G.I. Joe casualties were given heroes' funerals at Arlington National Cemetary.
