Clayton Cortez was a Marine and former Eaglestar contractor whose team was hired to take out the villagers of Ujanka for sabotaging a Roxxon pipeline. Growing a conscience amidst the massacre, Clay killed his own men, resulting in his capture and subsequent sale to Dr. Alba, the head of Weapon X's Batch-H division, which focused on the creation of Hulk/Wolverine hybrid mutant-killing cyborgs. H-Alpha was different from Weapon X's other subjects in many ways; firstly, he wasn't personally recruited by Director Stryker, so he wasn't a "true believer" of his cause; secondly, Alba left more of his brain than in other subjects, with the intention to better train and discipline him.
When the Hulk and a group of mutants investigated Weapon X and raided their central command, H-Alpha had fifteen minutes left of incubation before he could be released. The release of H-Beta bought Dr. Alba enough time to finish H-Alpha's process, and she eventually released him. H-Alpha joined the brawl between H-Beta and the Hulk. Due to his programming to act as an apex predator, H-Alpha beheaded H-Beta. He then turned on his creators, which Alba theorized was because H-Alpha had enough of his original brain to resent the atrocities they did to him. Hulk held him back, and they continued fighting. Once the Weapon X staff had fled the scene, H-Alpha abruptly stopped fighting, and escaped by jumping away.
In order to protect the family he barely remembered he had, Weapon H went from Eaglestar facility to Eaglestar facility wiping out every data about him they had so people like Stryker wouldn't target them. In one of such facilities, Clay ended up being injected with a nanite strain capable of resetting his command settings by Dr. Alba, who then commanded him to attack Stryker and his cyborgs. When Weapon H was commanded by Dr. Alba to kill the entire population of Phoenix to prove his perfection, the same group of mutants who raided the Weapon X central command with the Hulk, whom Weapon H had previously encountered and easily defeated, and Wolverine broke him free from Dr. Alba's control; prompting him to resume his mission of erasing any trace of his family to keep them safe.
Trying to stay off the radar, Clayton tried to pass as a Spanish worker, but he eventually lost control and transformed. Clayton attempted to stay away from civilians by hiding in the forest, but he found himself compelled to aid an archaeological expedition while keeping his distance after they were dropped without their rations case. When the expedition turned out to be a cover for the Roxxon Corporation to obtain a Wendigo, Clayton intervened and stopped the newly-created Ur-Wendigo from killing Dr. Ella Sterling, exposing himself to Roxxon by doing so. He tried to get Dr. Sterling to safety afterwards, but the Ur-Wendigo caught him mid-air and took a bite of him, growing larger than before. As he was about to be eaten whole by the Ur-Wendigo, Doctor Strange, who had been observing everything from the Sanctum Sanctorum, burst onto the scene and shoot some magic arrows at the monster, making it release Weapon H. Weapon H allowed himself to be eaten by the monster so he could use Doctor Strange's ax to kill it from within.
In the Olympic National Park in Washington, a bunch of Brood-infested wolves ran past some hikers as they hunted down Clay. After flashing back to a moment seven years ago to his honeymoon with Sonia, Clay arrived in Bellevue as he tried not to turn into Weapon H. It was then revealed that the Brood-Wolves were engineered by Roxxon under Dario Agger's orders as he instructed them to have the Brood-Wolves attack people. Clay used his claws to save prisoners on work release in Roseburg, Oregon from the Brood-Wolves. After slaying them, Clay turned into Weapon H to fight an Acanti and the Brood Drones that arrived. When Dario saw his fighting moves on the screen, a scientist stated that Weapon H somehow knew Krav Maga, jujitsu, and the Breakworld Death Punch, which Weapon H used to knock out the Acanti. Then Brood-Sky Sharks were unleashed as Weapon H started slaying them. Dario Agger had the scientist look up the database of the military organization that taught the moves that Weapon H had used on the Brood-infested creatures. Afterwards, Weapon H ripped a Brood-Human out of the Acanti as the Brood-Human stated that Roxxon only wanted to hire him. While stating that people who hired him to protect people actually want to kill people, Weapon H had the Brood-Human carry a message to Roxxon: to leave him alone. Clay was later seen flashing back to a moment with Sonia when Dario had the scientist initiate the spawn of a Man-Thing in the same forest.
Mutant / Gamma Mutate Cyborg: H-Alpha was subjected to experiments that grafted him the DNA of both Logan, the Hulk, and a host of other powered individuals. His skeleton was additionally bonded to Adamantium. H-Alpha also possesses the ability to change to and from his human form in spite of having his skeleton laced with Adamantium. It has been theorized nanotechnology reverse-engineered from Lady Deathstrike could make this possible. According to Dr. Alba, Weapon H could kill every living being on Earth.
- Superhuman Strength: Due to the fact that part of his DNA is part Hulk, Weapon H possesses the capacity for essentially near limitless physical strength, he showed this when he fought Amadeus in his original Hulk form.
- Superhuman Leaping: As the Weapon H is able to use his highly developed leg muscles to leap great distances. He even managed to cover a distance of 547 miles - 880 km in a single leap. Even when not in Hulk form, Cortez can still jump higher than a normal human; during the Fight with Wolverine, Cortez managed to jump several feet from grout level to the branch of a tall tree.
- Superhuman Strength Utilizations: Like the Hulk, Weapon H can inhale great quantities of air for several effects. For example, he managed to put out a massive fire that engulfed Redwood National Park and knocked down on Man-Thing.
- Superhuman Speed
- Invulnerability: Like Weapon H, Cortez gains massive physical resistance to physical damage due to increased density of skin and muscle and bone mass, and in combination with its adamantium skeleton and healing factor; to the point that it is extremely difficult, if not impossible to kill or injure him. The Weapon H skin is impervious to conventional blades, Adamantium and Vibranium being strictly the few known metals that can effectively pierce and penetrate his skin. Weapon H is bullet-proof, flame retardant, can resist massive exposures at point-blank range and falls from great heights. This invulnerability extends to the optic system since bullets. Even when not in Hulk form, Clayton is much more durable than a normal human due to the adamantium skeleton. Although he may be in human form, bullets can injure him if they hit his skeleton, and he has withstood blows from an enraged Hulk.
- Retractable Bone Claws
- Regenerative Healing Factor
- Enhanced Senses
- Probability Field Generation
- Alternate Transformation: Somehow Clayton is able to changed the gamma energy frequency in his body and turned him into Red Hulk-Harpy hybrid form, though it's only temporary. This form also give him additional ability and atrribute, include:
- Expert Combatant: As a former trained special operator for the Marine Corps, as well as the Navy SEALs, and later a mercenary, Clayton is very skilled in hand-to-hand combat. He was able to defeat several armed mercenaries with only his bare-hands. At some point in his past he was trained in the use of human and alien martial arts, as a scientist pointed out that Clayton was using Krav Maga, Jujitsu, and the Breakworld Death Punch to defeat the Roxxon Sky Whale F-10.
- Expert Marksman: As a former soldier, Clayton is also an expert on firearms and a fairly reliable shooter.
- Multilingual: Apart from English, Clayton is also quite fluent in Spanish, and perhaps some other languages as well.
Memory Loss: Clayton suffered some sort of amnesia and couldn't remember much about his past, except vague flashbacks of his time in the Eaglestar Corporation, as well as his first name. This is possibly a side effect of the experiments that were conducted on him by the Weapon X program.
Uncontrollable Rage: Just like Banner and Amadeus, possessing the power of the Hulk has given Clayton his own inner beast whom he has to constantly restrain, meaning he must always control his emotions if he doesn't want to lose control while in his Hulk form.
