From the Finale of Planet Hulk: 'He calls himself Worldbreaker because he knows that one day, his rage will burn this planet clean. But today the planet burns him. Sears him to the very bone. But he will not let her go. Today the Worldbreaker unbreaks his world.'
Pretty much the entirety of Planet Hulk is one, huge CMoA for our lovable, huggable, angry green guy.
The greatest moment in World War Hulk comes early on with Hulk vs. Black Bolt.
Hulk: I didn't come here for a whisper, I want to hear you scream!
During his first fight with the Galaxy Master, a Cosmic Entity, Hulk defeats him by jumping inside the Galaxy Master and ripping his mechanical core to pieces.
The entire Greg Pak run might count as one.
In their first battle with the Hulk, the U-Foes end up suffering from Power Incontinence and seemingly die on their own without the Hulk needing to do anything. In their second appearance, they've gained full control of their powers and managed to defeat the Hulk. They then hijack the world's TV broadcasts, stringing the Hulk up as Bruce Banner and threatening to murder him on live television. The rest of the hero community is trying to track Banner down so they can help him out, but they're either unable to find him because Vector is blocking their efforts to find Banner (Iron Man, Doctor Strange, etc.) or unable to get there to help him (Alpha Flight, Daredevil, Spider-Man, etc.) Eventually, Banner's friends rescue him, and he's in an extremely bad mood from being publicly humiliated by the U-Foes. He then Hulks out and proceeds to destroy the U-Foes one after another, to the point of forcing himself through Vector's repulsion waves with pure brute strength to get to him. Keep in mind that this is the usually mild-mannered Banner who's mad enough to do this, the guy derided by the various Hulk personas as a pathetic weakling. See what happens when you try Bullying a Dragon, boys and girls?
Hulk in the Dark Dimension. He's destroying everything... and he's so happy.
The rapid-fire show of what the Green Scar did to relax after being freed of the Banner persona: swimming with whales, roasting a shark over a fire on a mountaintop, exploring a Mayan temple, rodeoing a triceratops, bathing in an active volcano, wrestling an octopus, and climbing a mountain in a thunderstorm. All while wearing trousers and boots that fit him.
It's somewhat diminished by the fact that he was playing the pawn to Banner, but Hulk managing to take on two of his biggest rivals- Wolverine and the Thing- at the same time and beat them soundly, to the point where they both agree to never speak of the encounter again, counts for something. Special mention goes for twisting Wolverine's arm and stabbing him through the skull with his own claws.
While we're at it, Banner's whole manipulation of the Hulk in order to get everything he needs to find a cure...that he has no intention of using on the Hulk himself.
