Cure for Gamma Poisoning
Bruce Banner settled in Rocinha, the largest Favela in Rio de Janeiro, juggling his job in a soft drink bottling factory with attempts to find a cure for his condition. In order to control his emotions and heart rate and prevent his transformations, Banner also studied martial arts and meditative breathing techniques with a Brazilian jiu-jitsu instructor. This lessons allowed him to control and prevent his transformations for five months.
The search for a cure for his condition drived Banner to study a flower described in the book "Inventory of Rare and Endangered Tracheophyta of Amazonia", and he finally received it that day. Banner contacted a man who helped him through his research, codenamed "Mister Blue", to inform him of the discovery. Blue advised him to try a high dose of the component extracted from the plant, and he was able to produce a serum using homemade laboratory equipment.
Banner tried the serum on a blood drop, and while it seemed to be succesful at first, it triggered a reaction that made the cells explode. Informing Mister Blue of the failure, Blue insisted to meet Banner in person, as living with Gamma poisoning could be more dangerous than the eventual risks of their meeting, and convinced him to send a blood sample.
A few days later, Banner received news from Mister Blue, as preliminary blood tests showed significant gamma reduction, but as he asked for more data, Banner realized he should return to Culver University to retrieve it.
General Thaddeus Ross managed to locate Banner after learning that a man in Milwaukee suffered a severe case of Gamma poisoning after drinking from a bottle that got impregnated with Banner's blood while he suffered a cut in the factory. Ross assembled a team led by Russian-born British special operations expert Emil Blonsky, to capture Banner.
Ross and his unit located Banner's house and burst in to shoot him with tranquilizer ammo, but Banner fleed through the window and momentarily hid with Martina, one of her co-workers, at her house, in order to deceive the military. Blonsky and the other soldiers pursued Banner through the streets and rooftops of Rocinha, while Banner tried to slow down his heart rate to prevent his transformation.
While fleeing Banner came across General Ross, realizing he was the man behind the chase, and also a man who almost got into a fight with him when Banner prevent him to molest Martina at the factory. This man also pursued Banner with his friends to the bottling factory in order to beat him. Blonksy located Banner in the factory and approached to witness the appearance of Hulk, as the transformation was triggered by the men beating him.
Ross and Blonsky returned to Banner's house after his escape, to search for evidences that would indicate Banner's next step, finding a photograph of Betty Ross and Banner's computer. Blonsky asked for the nature of Hulk, and Ross confessed that Banner was that creature, without further details.
