Avengers Vs. X-Men is the 12-issue series that the Marvel Comics is billing as "the biggest comic book event in history." Written by the publisher's "Architects" -- Jason Aaron, Brian Michael Bendis, Ed Brubaker, Matt Fraction and Jonathan Hickman -- and drawn by fan-favorites Olivier Coipel, Andy Kubert, and John Romita, Jr., the event will tie-in to Marvel's main Avengers and X-Men titles, as well as the spinoff miniseries AVX: Versus.

Below you will get your first look at Walt Simonson's cover for Avengers #26, the second issue of the venerable artist's six-part run with series writer Brian Michael Bendis, as well as all of the new AvX covers Marvel has been transmitting throughout the week.

Simonson's Avengers work begins with April's issue #25, representing his first monthly gig ince DC Comics' Orion concluded almost ten years ago, and will tie-in with Marvel's high profile Avengers Vs. X-Men event.
