There's one more thing: the strongest connection between the Avengers and Thunderbolt is precisely Bruce Banner: the General has a timeless bone to pick with Banner. He is part of the Hulk's mythology.

Do you actually think the Russos would have made room for Thunderbolt in Civil War just because they were hit by nostalgia? Is General Ross a merely decorative character?

If there's a catch to Thunderbolt's return, it has got to be that: becoming the Red Hulk is a matter of time for Ross, so why not do it in Civil War?

Why not? Well, that's actually a good question, "˜cause inviting the Red Hulk in Civil War must be extremely consequential.

What does that mean?

If the Red Hulk shows up, the obvious supposition is the Hulk will be there too. Because why else would Ross turn? However, Mark Ruffalo is not confirmed for Captain America: Civil War.

Moreover, the last Hulk scene in Age of Ultron made it pretty clear the Green Goliath made up his mind about leaving the world behind and setting his course on a life of solitude.

He would actually need a really strong reason to return to his fellow Avengers, and a threat like the Red Hulk is good enough.

Now, what do you guys say? Do you think the Russos will make room for the Red Hulk in Civil War? Would you like to see the clash between the two Hulks on screen?
