10 Hulk Fates Worse Than Death
6. That Time The Hulk Hit On His Cousin - Incredible Hulk Annual 2000
The Old Man Logan storyline showed the world what happens when everything goes to Hell, and the world comes to an end. The Hulk gets it on with his cousin to create a Hulk Gang of inbred freaks, but that's only one alternate possible future that could happen.
In the real-world environment of Earth-616, there's no hanky-panky going on between the Hulk and She-Hulk, as that would be incestuous and nasty... right? Indeed, the line was never crossed in the normal Marvel Universe, but the Hulk came close to it once, and knowing that it happened isn't great for Bruce.
Back in The Incredible Hulk Annual 2000, the Hulk finds himself in a somewhat romantic mood, so he heads out to find someone to sate his desire. Problem is there's really only one possible woman on the planet Hulk thinks can fulfil that desire, and that person was (just like in Old Man Logan) She-Hulk, so he went looking for her.
He wasn't exactly in his right mind at the time, but that doesn't change what he did. He tried to "assert his dominance over her." Jen was able to rebuff his advances, but that doesn't change the fact that it happened. Jen and Bruce were left to live on with the knowledge that he tried, and that's not the kind of info many people would want to live with.
