A Hulk Clone

TIH2 #448: From cell scrapings of the
Hulk, the
Pantheon created a brainless clone of the Hulk, and killed it in front of cameras (by shooting three bullets straight to the brain through the eye using a powerful hand gun). The clone was then sent to the government for ID purposes. The Pantheon's plan was to make the US Government believe that the Hulk was dead while bring the Hulk back to their team, giving him a low profile so his existence was not revealed. However, the Hulk refused the proposition.

TIH2 #315: Using a nutrient bath in a tank of his invention,

Psyklop.
TIH2 #200:
Bruce Banner controls the Hulk's form using the

TIH2 #272: Thanks to several treatments with Gamma radiation,
Bruce Banner gained control over the
Hulk's form. Thus, the
Banner Hulk persona (or incarnation) emerged. Banner eventually lost control over the Hulk, in part due to nightmares created by
Nightmare.
Bruce Banner is Cured!
TIH2 #223: While enraged, the
Hulk reverts back to a green-skinned
Banner. After realizing this, Banner lights up burning all of his gamma energy. His skin color is back to normal and he's not able to turn into the Hulk even under periods of great stress and anger. Soon after, however,
Doc Samson bathed Banner with gamma rays to save his life (TIH #225), which brought back the Hulk.
TIH2 #250: The
Silver Surfer purges the gamma radiation from the cells of
Bruce Banner, curing him from becoming the
Hulk. In exchange, the Surfer asks Banner to help him break the

TIH3 #102: The
Hulk becomes the king of planet Sakaar after defeating the tyrant
Red King. The Hulk had chosen
Caiera as his wife, thus making her the planet's queen. The Hulk was regarded as "the Green King". Unfortunatelly, the Hulk's ruling only lasted for three days: An blast of atomic bomb proportions destroyed Crown City and killed most of the population, including Caiera and her unborn child.
The Hulk was made to believe that the
Illuminati were responsible for the blast and with his Warbound, he departed for Earth in search of revenge.
Previously, the Hulk almost became the king of K'ai city in a microverse planet when he was to marry queen
Jarella (The Incredible Hulk #140). But
Psyklop caught and brought the Hulk back to Earth before he could marry her.
The Hulk Becomes a Slave
TIH2 #302: While in the Crossroads, the
Hulk enters a deserted world attracted by the visions of a green-skinned maiden whose tears produce flowers. In such a world, the Hulk's great strength was somehow cancelled, thus he was easily defeated by

Iron Knights from the City of Death), locked in shackles the Hulk could not break, and finally made a slave. The aliens called the Hulk "Garaman" which means demon or gargoyle in their language.
TIH3 #92: Right after passing through the interdimensional portal that brought him to planet Sakaar, the

View Image The Hulk Can Fly
TIH1 #3: The
Hulk rescues
Rick Jones from the Army and flies away. Perhaps the cosmic rays that bathed him earlier aboard the rocket gave him the ability to fly. This largely unknown Hulk power wore off soon after, probably due to further exposures to gamma rays. Hulk has not been able to fly ever since.

TIH2 #156: When
Bruce Banner was in full control of the
Hulk's form in the microscopic world of
Jarella,
Lord Visis used a device that brought Banner's greatest fear to life: the "savage" Hulk. The two Hulks fought until the wizards from K'ai removed the control Banner had over the Hulk, turning him into the savage Hulk, after which the replicate disappeared.
TIH2 #453: The
Hulk fights a version of himself that has long hair and is from an alternate reality. The second Hulk was brought to this reality because the original Hulk is a walking nexus of reality after his involvement with Onslaught
(which separated
Bruce Banner from the Hulk).
The Hulk is Psychoanalized
TIH2 #227: Dr.
Leonard "Doc" Samson analyzes the
Hulk several times to study his fragmented psyche and try finding a cure at the psychological level. The first time, Doc Samson injected a calibrated dose of gamma epinephrine in
Bruce Banner to trigger the transformation into a calm, relaxed Hulk he could work with. Then, Doc Samson placed a headset called rem-integrator in the Hulk's head and with alpha waves, the Hulk was put into a deep, dreaming sleep.
The Hulk Uses Weapons
TIH2 #390: The Professor
Hulk used large Pantheon machine guns to cut through the Trans-Sabal troops, armed with SHIELD equipment. He certainly didn't need them.
The Hulk Wears Glasses
TIH2 #421: The Professor
Hulk sometimes wore glasses. The Hulk Library Contributor
Allan MacKinnon has the following explanation of why the Hulk needs to wear them:
"I have read that people who have multiple personalities can exhibit physical conditions (like diabetes) that the person does not normally have but are associated to a single personality. This may be the case with the Professor Hulk where the condition of far-sightedness is induced in this Hulk personna which requires him to wear glasses when reading."
