What seemed to be the case was the individuals would realize that "Giant-Man" is kind of a corny name. They (and even Clint Barton) later went by the name of Goliath when using size-altering powers.
Today, Marvel has announced that Giant-Man will be returning. The question is, who is Giant-Man now? Obviously someone with blue eyes. Hank Pym does have blue eyes and maybe he realizes that calling himself Wasp isn't the best idea.
We can probably safely assume it's not Hank. A clue is the fact that this appears to be happening in Avengers Academy. Based on this image, the face has a younger look to it so it's most likely some young new 'hero' that will be taking the name.
When is this issue coming out and what will be his involvement with the other members of the Avengers Academy?

We'll find out in December when issue #7 goes on sale. It'll be written by Christos Gage and penciled by Mike McKone. What are your thoughts on another Giant-Man? Is the Marvel Universe ready and big enough for yet another?
