When Marvel was acquired by Disney there was a lot of over reaction that they would put Disney Characters into Marvel comics, and while that provided some fun fan art, there is no reason to assume that Disney will be making any direct changes to Marvel Comics with their existing properties.
Cross promoting their films however is a completely different story.
To promote the upcoming Tron Legacy, a number of Marvel Comics will have variant covers available that re-imagines the characters if they were to exist in the world of Tron.
•Amazing Spider-Man #651 TRON Variant, featuring Spider-Man
•Avengers #7 TRON Variant. featuring Spider-Woman
•Avengers Academy #7 TRON Variant, featuring Quicksilver
•Invincible Iron Man #33 TRON Variant, featuring Iron Man
•Wolverine #4 TRON Variant, featuring Wolverine
•Incredible Hulks #618 TRON Variant, featuring Ghost Rider
•New Avengers #7 TRON Variant, featuring Ms. Marvel
•Thor #617 TRON Variant, featuring Thor
•Captain America #612 TRON Variant, featuring Captain America
•Secret Avengers #7 TRON Variant, featuring Moon Knight
Of course these will not impact the actual storylines, nor will it change the books in any way. Just interesting to see some professional art with some of our favourite Marvel characters in the world of Tron.
These look very awesome.
