The Avengers: Earth's Mightiest Heroes series is here... almost. Over at Disney.com the first episode of a micro series has arrived titled Iron Man is Born! This 5-minute spot is the first of 20 daily segments leading into the series TV debut. Unsurprisingly, the episode focuses on Iron Man who takes on Hydra single handedly ending in a cliffhanger. Tomorrow The Coming of the Hulk is scheduled to debut.
