Now if you're all over the canon of Marvel, this is old news to you. But for many, the question "what is that giant worm in Avengers 2012?" is likely to be asked.

And to support my answers, [url=http://splashpage.mtv.com/2012/03/02/avengers-trailer-ending-fin-fang-foom/]this[/url] article suggests the same.
