Hulk different from Bruce Banner
Alternative versions of Hulk
A number of alternate universes and alternate timelines in Marvel Comics publications allow writers to introduce variations on the Hulk, in which the character's origins, behavior, and morality differ from the mainstream setting. In some stories, someone other than Bruce Banner is the Hulk.
In some versions, the Hulk succumbs to the darker side of his nature: in "Future Imperfect" (December 1992), a future version of the Hulk has become the Maestro, the tyrannical and ruthless ruler of a nuclear war-irradiated Earth, and in "Old Man Logan" (2008), an insane Hulk rules over a post-apocalyptic California and leads a gang of his inbred Hulk children created with his first cousin She-Hulk.Characterization
Like other long-lived characters, the Hulk's character and cultural interpretations have changed with time, adding or modifying character traits. The Hulk is typically seen as a hulking man with green skin, hair, and eyes, wearing only a pair of torn purple pants that survive his physical transformation as the character progressed. As Bruce Banner, the character is about 5 ft 9 in (1.75 m) tall and weighs 128 lbs (58.05 kg), but when transformed into the Hulk, the character stands between 7 and 8 ft (2.13 - 2.43 m) tall and weighs between 1,040 and 1,400 lbs (471.73 - 635.02 kg). The Gray Hulk stands 6 ft 6 in (1.98 m) tall and weighs 900 lbs (408.23 kg); the Merged Hulk stands 7 ft 6 in (2.28 m) tall and weighs 1,150 lbs (521.63 kg); the Green Scar stands 8 ft 8 in (2.64 m) tall and weighs 2,400 lbs (1.08 ton). The Immortal Hulk is roughly the same size as Sasquatch, standing around 9 or 10 ft (2.74 / 3.04 m) tall and weighing roughly 2,000 lbs (907.18 kg). Following his debut, Banner's transformations were triggered at nightfall, turning him into a grey-skinned Hulk. In Incredible Hulk #2, the Hulk started to appear with green skin, and in Avengers #3 (1963) Banner realized that his transformations were now triggered by surges of adrenaline in response to feelings of fear, pain or anger. Incredible Hulk #227 (1978) established that the Hulk's separate identity was not due to the mutation affecting his brain, but because Banner was suffering from dissociative identity disorder, with the savage Green Hulk representing Banner's repressed childhood rage and aggression, and the Grey Hulk representing Banner's repressed selfish desires and urges.Identities
Bruce Banner
During his decades of publication, Banner has been portrayed differently, but common themes persist. Banner, a physicist who earned his Ph.D. in nuclear physics from the California Institute of Technology (Caltech), is sarcastic and seemingly very self-assured when he first appears in Incredible Hulk #1, but is also emotionally withdrawn. Banner designed the gamma bomb that caused his affliction, and the ironic twist of his self-inflicted fate has been one of the most persistent common themes. Arie Kaplan describes the character thus: "Robert Bruce Banner lives in a constant state of panic, always wary that the monster inside him will erupt, and therefore he cannot form meaningful bonds with anyone." As a child, Banner's father Brian often got mad and physically abused both Banner and his mother, creating the psychological complex of fear, anger, and the fear of anger and the destruction it can cause that underlies the character. Banner has been shown to be emotionally repressed, but capable of deep love for Betty Ross, and for solving problems posed to him. Under the writing of Paul Jenkins, Banner was shown to be a capable fugitive, applying deductive reasoning and observation to figure out the events transpiring around him. On the occasions that Banner controlled the Hulk's body, he applied principles of physics to problems and challenges and used deductive reasoning. It was shown after his ability to turn into the Hulk was taken away by the red Hulk that Banner has been extremely versatile as well as cunning when dealing with the many situations that followed. When he was briefly separated from the Hulk by Doom, Banner became criminally insane, driven by his desire to regain the power of the Hulk, but once the two recombined he came to accept that he was a better person with the Hulk to provide something for him to focus on controlling rather than allowing his intellect to run without restraint against the world.
