Captain Mediocre

In whatever movie Hulk shows up in next, it should be revealed that Professor Hulk isn't actually Banner, and is instead a super intelligent Hulk made intelligent by gamma rays. This will lead to Banner separating himself from Hulk and Hulk going on a rampage across the US and Canada (Wolverine could possibly be introduced like in Ultimate Hulk vs Wolverine as someone sent to attempt to kill the raging Hulk) because he's pissed at Banner for keeping him locked up for so long. This prompts General Ross to release Abomination from his prison, and maybe even become Red Hulk himself to fight this new Hulk. It ends with Banner and Hulk almost dying because they can't live without each other and so they merge again and come to an agreement
