[Marvel] Could Phoenix disintegrate Hulk?
gpt
One of the fundamental forces of the Universe, the Phoenix, could easily defeat the Hulk. The Phoenix spirit has a rage to match Banner's. Plus she has telepathy that could force him to alter to a Banner state, assuming he wasn't directly threatened. Finally, if you look at it on a pure comparison of energy, the Phoenix eats stars. Now, we're talking full on Phoenix force here. But ultimately, it doesn't matter how much energy Bruce has at his disposal. The phoenix force can take an ACTUAL gamma ray burst and come out shiny and full in the tummy.

The only time the Phoenix has been restrained was with the M'kraan crystal, created specifically to contain it, or by it's host forcing it to blink. So yeah, there's at least one Marvel entity that the Hulk can't top.
