It might be just artist interpretation, but check out new art below released by Marvel for The Avengers 2 where one of the posters features the Gray Hulk.
The Gray Hulk was a smarter version of the Hulk in the Marvel Universe comics, but also the version in the Ultimate Comics.
Footage from the Avengers 2 seemingly revealed Ruffalo’s Hulk colored gray (see above) leading to speculation that something goes down to cause the Hulk to transform into a different version of himself.
Marvel will be showcasing the art as part of Marvel Studios & Hero Complex Gallery April 24 – May 17 at the Hero Complex Gallery in Los Angeles (free custom collectible chocolate bars for opening night attendees while supplies last!).
