Captain America Ironman Figure

Who is this superhero?

I bought a T-Shirt Marvel other day and he has five or six superheroes in it including Ironman, Captain America, Spider-Man, Storm, Wolverine and Hulk. But there is a superhero on the shirt that I can not figure out who he is, even after searching the site of Marvel and google. Does anyone know? Here is the link to the image:% http://i528.photobucket.com/albums/dd330/tallguy12219/Mystery 20Hero/MysteryHero.jpg

The shirt you have is the line-up of comics Marvel Adventures Avengers. The superhero is you can not find Giant Girl. Hence it is so big there in the background, it is really Janet Van Dyne (also known as the Wasp in regular continuity). Giant Girl was created for the comics to give to another member of the female team. Marvel Adventures Avengers is an all ages comic book set outside the normal continuity of new readers. It's really nice surprise if you ever get the chance to get him.
