Banner's, decrying Banner as "puny Banner." From his earliest stories, the Hulk has been concerned with finding sanctuary and quiet. He is often shown to quickly react emotionally to situations. Grest and Weinberg call Hulk the "dark, primordial side of Banner's psyche." Even in the earliest appearances, Hulk spoke in the third person. Hulk retains a modest intelligence, thinking and talking in full sentences. Lee even gives the Hulk expository dialogue in issue #6, allowing readers to learn just what capabilities Hulk has, when the Hulk says, "But these muscles ain't just for show! All I gotta do is spring up and just keep goin'!" In the 1970s, Hulk was shown as more prone to anger and rage, and less talkative. Writers played with the nature of his transformations, briefly giving Banner control over the change, and the ability to maintain control of his Hulk form. Artistically and conceptually, the character has become progressively more muscular and powerful in the years since his debut. Joe Fixit Originally, Stan Lee wanted the Hulk to be grey. Due to ink problems, Hulk's color was changed to green. This was later changed in the story to indicate that the grey Hulk and the savage Hulk are separate dissociative identities or entities fighting for control in Bruce's subconscious. The Grey Hulk incarnation can do the more unscrupulous things that Banner could not bring himself to do, with many sources comparing the grey Hulk to the moody teenager that Banner never allowed himself to be. While the grey Hulk still had the-madder-he-gets, the-stronger-he-gets part that is similar to the savage Hulk, it is on a much slower rate. It is said by the Leader that the grey Hulk is stronger on nights of the new moon and weaker on nights of the full moon. Originally, the night is when Bruce Banner became the Grey Hulk and changed back by dawn. In later comics, willpower or stress would have Banner turn into the grey Hulk. During one storyline where he was placed under a spell to prevent him turning back into Bruce Banner and publicly presumed dead when he was teleported away from a gamma bomb explosion that destroyed an entire town, the grey Hulk adopted a specific name as Joe Fixit, a security guard for a Las Vegas casino owner, with the grey Hulk often being referred to as Joe after these events.
