Back in the present, in the aftermath of their world-shaking battle against the Dark Celestials, the new Avengers team is officially formed -complete with a startling new headquarters at the top of the world! Behold the wonders of Avengers Mountain. But someone who doesn't seem impressed is Namor, the ferocious lord of Atlantis -and his rage may turn the oceans red with blood! COLLECTING: AVENGERS 7-12
