I would be surprised to see Mr. Fixit in The Avengers 2, but I would love it, and anything from Peter David’s run would make a great standalone Hulk movie.
If what a new toy suggests, it’s possible the Grey Hulk may appear in The Avengers: Age Of Ultron.
A promotion for the Funko POP! Vinyl Avengers 2 toys features the Grey Hulk, which of course, could just be for the merchandising line, but imagine if at the end of Avengers 2, Banner/Hulk are thought to be dead, and we end up seeing the Grey Hulk in Las Vegas. I know I may be dreaming, but it would be awesome.
The Grey Hulk was actually the first personality/version of the Hulk, but the coloring was changed to green with a different personality. The Grey Hulk is weaker than the Savage Green Hulk, but smarter and more cunning. Marvel Comics writer Peter David brought the Grey Hulk back with Incredible Hulk #324.
“The Avengers: Age Of Ultron” hits May 1, 2015 directed by Joss Whedon starring Robert Downey Jr., Chris Evans, Chris Hemsworth, Scarlett Johansson, Mark Ruffalo, Jeremy Renner, Samuel L.
