Marvel has hit a milestone by breaking the three million fan mark on their Facebook page. To celebrate this achievement and to thank their fans, Marvel will be releasing exclusive news, artwork, and previews of their upcoming shows and video games all day long – but only on Facebook.

To kick things off, Marvel released this teaser image for the upcoming season of their hit animated show Avengers: Earth’s Mightiest Heroes. As you can see, it looks like the Fantastic Four will be making an appearance this season, as will Dr. Doom.

This is an exciting day for fans of Marvel. Aside from today’s Facebook celebration, Marvel has also scheduled another “Mystery Liveblog” for their Next Big Thing series.
