The Dark Reign storyline is really shaking some things up in the Marvel Universe. Mighty Avengers #21 will be a Dark Reign tie-in and will introduce a new team of Avengers. While Marvel has been very tight-lipped on exactly who will make up the new team, the cover to Mighty Avengers #21 reveals that Hank Pym, Jocasta, and Scarlet Witch will be three of the members. The giant-sized Mighty Avengers #21 will also guest star the New Avengers, Dark Avengers, Young Avengers and Classic Avengers. Marvel is promoting the issue as a great jumping on point for new fans. Mighty Avengers is written by Dan Slott with pencils and cover by Khoi Pham. Mighty Avengers #21 is scheduled to hit comic book stores on January 14, 2009.
