of his Hulk formula combined with Captain America's blood, which causes him to transform when under stress into a gigantic monstrous form that is virtually impervious to harm, and which possesses vast physical strength and stamina. His strength appears to be peerless in the Ultimate universe, as he tosses heavy-hitters such as Iron Man and Thor around like dolls and ripped the Adamantium needle prepared for him like a toothpick. He also tore Wolverine in half despite the presence of his Adamantium laced skeleton. He is also tough enough to survive a nuclear detonation, seeing as how he is still alive after the attempted execution. Hulk can regenerate tissue and broken bones almost instantly, making him an almost impossible enemy to defeat; so far only two defeats have been witnessed, both involving forced transition back to Banner. Firstly where Hulk was suffered Wasp's "stings" directly to his frontal lobes, followed by impact trauma incurred from a height upwards of five thousand feet. Secondly, Hulk can be forcibly transformed back to Banner form through direct injection of a serum created by Bruce Banner himself; injection is possible only via adamantium needle that can either be directly applied, or fired into the target. The second option was employed by Hawkeye (under General Fury's command) after the alien invasion had been defeated at the end of Ultimates vol. 1, in the aptly-named issue "How I Learned To Love The Hulk". Personality and behavior This Hulk, like many Ultimate Marvel characters, has base similarities to his mainstream Marvel Universe counterpart coupled with differences. He is very angry and has not shown much intelligence, like the Savage Hulk. However, the Ultimate Marvel version of Hulk is a lot more vicious and violent than his mainstream counterpart. For example, Hulk has ripped Ultimate Wolverine in half and ripped off Herr Kleiser's head. Further, he once threatened to rip out Hank Pym's skull and use it as a toilet. This Hulk is also just as much more sexual. On many occasions, Hulk has yelled out to Betty, telling her how "horny" he is and he also surrounded himself with beautiful women in Tibet. Finally, the Ultimate version of Hulk is a cannibal, as demonstrated in Ultimate Wolverine Vs. Hulk #2, where the Hulk devours his farm coworkers for making fun of Banner's being a vegan and questioning his sexuality. In other media The Hulk appears in Ultimate
