Hulk as well as another more menacing personality that is emerging within him. Working alongside psychotherapist Doctor Leonard Samson, Banner nearly completes the device, but military forces led by Emil Blonsky destroy his forest hideout. As Banner escapes in the form of the Hulk, Blonsky takes the device from the hideout's remains and is exposed to gamma rays. Banner regroups with Samson, who equips Banner with a device that implants post-hypnotic suggestions and artificially induces episodes of rage, allowing them a degree of control over the Hulk. Samson sends the Hulk on various errands into the city and the badlands, either to help construct the machine or to hinder Blonsky's ever-growing presence. Meanwhile, Blonsky's superior General Thunderbolt Ross chastises him for overstepping his authority to secure a mysterious prisoner, "Mission Directive", in a secret military research facility known as the Vault. Following this argument, Blonsky transforms into a massive reptilian creature known as the Abomination and goes on a rampage until the Hulk arrives and defeats him. As the Hulk escapes, Blonsky returns to normal and claims to his men that the wreckage is the Hulk's doing. While retrieving fuel rods at a nuclear power plant, the Hulk encounters Blonsky's bodyguard Mercy.

Samson, fearing the threat of an out-of-control Hulk, lures the Hulk into a military test site, where Ross faces the Hulk in a gigantic Hulkbuster mech. When the Hulk emerges victorious, Samson renders the Hulk unconscious with his hypnotic device. Banner is taken to the Vault, where Blonsky prepares to peel open Banner's mind in search of the secret to controlling gamma-based transformations. The agony of Banner's interrogation draws out the Devil Hulk's power, and the Hulk breaks free. Blonsky transforms into the Abomination when the Hulk corners him, exposing his identity to the military. Blaming the Hulk for ruining his life, the Abomination flees the Vault, as does the Hulk. Banner confronts Samson for betraying him, but forgives him when Samson
