Force Works was composed of the remains of the West Coast Avengers.
Shortly after the death of Mockingbird, the West Coast Avengers disbanded, understandably Hawkeye left while in mourning the death of his wife, War Machine went solo, and the rest were removed from the Avengers charter after the events of Crash and Burn. The team was reformed as Force Works by Iron Man, US Agent, Scarlet Witch, Wonder Man, Spider Woman (currently Arachne), and later the alien Century and for a brief time War Machine joined the team, but chose to leave due to personal problems with Iron Man.
After the events of the Civil War, the name Force Work's was given to The Initiative team from Iowa as part of the 50-state Initiative. The members of this current team are still unknown.
