The World War Hulk storyline was pretty cool. The Hulk went on a ****ing tear.. I loved when he confronted Black Bolt and said something to the effect of "I didn't come to hear a whisper. I want to hear you scream."
Spoiler!
.. And when he confronted Professor X at the X Mansion and all the mutants are trying to protect him. He broke Colossus' arms, beat the ever living shit out of Wolverine, and out smarted Juggernaut. Then Darwin came up and, in adapting to survive, all his powers would do was teleport him away to safety
I was able to find some pics:
Man, that was a pretty cool comic. I really hated his fight with the Sentry though. That shit just got too weird for me.
