While it still remains a piece of the Marvel Cinematic Universe, for the most part The Incredible Hulk tends to be mostly ignored except for when it comes to Bruce Banner and General Ross who returned years later in the Captain America: Civil War. For years fans have wondered about the fate of the two villains introduced in the film and it appears Kevin Feige is well aware of this. When asked about the fate of The Abomination and The Leader while speaking with Crave Online, the Marvel Studios head commented briefly on their whereabouts.
“It is an embarrassment of riches of places we could go or characters we could reprise or bring back now that we’re… I think Ragnarok is our seventeenth MCU film. And you would be surprised how many… it’s come up. It’s come up. Just finding the right place. And as I said, if you can’t do it right, don’t do it or do it later, and the notion of “Hey, I’m here too! Next!” is not interesting to us. Abomination is in a prison somewhere too.'”
