Enclave

The Enclave is a conglomerate of scientists with their own private army who use New York City as their own test site.

History
The Enclave is an organization of scientists, divided into at least four different sectors, and operating behind a front company called the Paragon Corporation to conceal their illegal activities.

The Ceres Sector is a Chemical Weapon and Genetic Engineering Division. They tried to eliminate Rick Jones, set up chemical bombs for poisoning key areas in New York City, and then occupied them with their own troops. They were responsibles of building the Bi-Beast to fight Hulk.

The Minerva Sector is the Psych-Ops Division. They used energy siphoning machines to drain the city's power, and even its citizens' bio-electric life force. They also used mind-control devices to try to enslave all New York.

The Jupiter Sector is the Weather Manipulation Division. They used earthquake generators and orbiting laser satellites to attack Hulk.

The Vulcan Sector is the Mechanical Design Division. They unleashed giant Kyklops robots, laser turrets to destroy Hulk, and deployed a giant weapon called the F-Pod to destroy the city.

After their repeated failures, the leaders of the different sectors realized that they needed to defeat Hulk by confronting him directly or if they were lucky, let the United States Armed Forces take care of him for them.
