The above picture was posted on the same interview where Jeph Loeb and Joe Quesada talked about the upcoming Avengers Assemble animated series. In the same interview, the two Marvel big daddies had this to say:
TV Guide Magazine: What else is coming from Marvel Animation Studios?
Jeph Loeb: This was a major step forward for us and it’s been a chance to both maintain the creative control that Marvel has been so successful with and at the same time be able to push the boundaries in animation. There are two huge projecta that we’re working on. The first, we know the impact that The Avengers had — and continues to have — this summer, and there’s one particular character who has been the breakout hit of the summer and he’s big and he’s green and he’s our Incredible Hulk. So we started talking about it and we thought what’s more fun than one Hulk? And that would actually be five Hulks! We’re taking characters that already exist in the Marvel Universe — because it’s very important to us that it all begins with [the comic-book] publishing. That cast is Hulk; the Red Hulk; Skaar, who’s the teenage barbarian Hulk, She Hulk — who’s actually been a character in the Marvel Universe for 30 years; and a relatively new character, A-Bomb. He’s more of a Blue Hulk. And together they are Hulk and the Agents of S.M.A.S.H.
TV Guide Magazine: What does S.M.A.S.H. stand for?
Jeph Loeb: Joe had that answer the first day: They’re Hulks, it can stand for anything they want it to.
