Secret Avengers

When Steve Rogers took over Norman Osborn's role as top cop, he chose not to continue H.A.M.M.E.R. or to reestablish S.H.I.E.L.D. Instead, he decided to put the world's security into the hands of a few Avenger teams. One of these teams became the Secret Avengers, and he took direct leadership of it with Sharon Carter assisting him with tactical operations. The purpose of this team was to covertly clean up the messes left by the Osborn administration.

To this end, Steve personally recruited a team that would allow him to carry out surgical strikes in any given circumstance. This included experienced covert operators like Black Widow, Moon Knight and Ant-Man; a scientist in Beast; a one man army in War Machine; a powerful magical warrior called the Valkyrie, and the cosmos' top cop Nova. Their first mission involves the Roxxon Oil company and their excavation in the planet Mars where they are searching for a Serpent Crown. Steve Rogers first send Nova in the planet but when he hadn't heard from him, he goes with his team for a attempted rescue mission. Unknown to him that Nova has already found the Serpent Crown and is tempted to put it on.
