"The series was announced at the 2011 Comic-Con. Marvel Entertainment's Head of Television Jeph Loeb called up writer Paul Dini to "ask" him if he wanted the job. The two had done the same thing the previous year for Ultimate Spider-Man. 
The Avengers: Earth's Mightiest Heroes was actually going to focus on the Hulk and be called Hulk: Gamma Corps. It was in pre-production but was folded into The Avengers: Earth's Mightiest Heroes, which was also in production. Joshua Fine, the Director of Animation Development for Marvel Animation, said "It became apparent to us that the creative work that was being done to bring Hulk’s world and his villains to life was too good to relegate to his universe alone, and would be much better suited as part of an full-on Avengers scenario." Gamma Corps producer Ciro Nieli left the cancelled series and came to work on Avengers.  It is currently unknown if anything from Gamma Corps eventually became Agents of S.M.A.S.H."
