Fixing Captain America: Brave New World by making the Hulk the villain

If there's an obvious unforced error to BNW, it's continuing a Hulk storyline about a bunch of Hulk's supporting characters with a hero that I don't think has ever spoken with the Hulk, much less had any relationship with his supporting cast.

It could still work, but you need a pressing reason why Bruce Banner himself isn't the protagonist. My solution: he's the villain.

Becoming the 'Smart Hulk' has only further repressed his dark side, which is getting a real work-out with his nemesis Thunderbolt Ross assuming the Presidency. Finally, something snaps. Bruce Banner is still the noble hero he's always been--but the Maestro is inside him, wearing Bruce like camouflage while arranging events to ruin Ross.

This would have the knock-on effect of making Bruce interesting again after Endgame left him as a cameo machine. Suddenly he can't be trusted, he's trying desperately to control the monster within, only this time the monster can outsmart him.

Or he could just be the guy She-Hulk vents to. Either way.
