Writer J. Michael Straczynski is a fan favorite for his Marvel work on characters such as Thor, Spider-Man, and his current Captain America run, and now he's returning to some of those characters as well as bringing in many more - including some lesser known classics - for a series of team-up one-shots that span the Marvel Universe.
In each of the six one-shots, Straczynski will bring together pairs of heroes and villains that rarely cross paths (and a couple of all-time classic pairings) for "timeless" adventures that exist on the hazy fringes of continuity. Artist Leinil Francis Yu has created some promo art featuring all the characters involved, seen here:
