In 2004, Austen also wrote "The Avengers" from #77–84. His first arc introduced a new, female Captain Britain (since renamed Lionheart), a single mother thrust into the realm of super-heroes after being killed as an innocent bystander during a fight between the Avengers and the Wrecking Crew, only to be resurrected by the original Captain Britain. The second arc, which saw Austen writing former Avengers U.S. Agent and Namor the Sub-Mariner attempting to liberate a Middle Eastern country from its corrupt leadership, served as launching pad for the short-lived 2004 "Invaders" series.
