Marvel Asks "Who Is Hulk?"

Marvel Comics has released a series of new teaser images asking "Who is the Hulk?"

The teasers a lead-in to the new Totally Awesome Hulk series, launching with writer Greg Pak and artist Frank Cho this fall.

The identity of the Hulk has been kept a mystery, and the new teasers show new silhouettes that could be some of Marvel's biggest heroes, like Iron Fist or Thor, or one of Hulk's greatest villains, like the Maestro.

UPDATE: Marvel has released a fourth teaser, this one seeming to suggest...Loki is the Hulk?

Or these could just be huge red herrings meant to keep fans guessing. We won't know for sure until Totally Awesome Hulk launches as part of All-New, All-Different Marvel.
