Quote: "Whatever they're planning... we intend to be ready."
Agent Nick Fury is the director of the secret government agency of S.H.I.E.L.D. (Strategic Hazard Intervention Espionage Logistics Directorate). He was assigned originally to lead the 'metahuman special ops', including such members as Weapon X, Warbird and Captain America. Trask also worked under him briefly, working on mutant containment measures and counter measures, but eventually severed his ties with SHIELD. Fury's main troubles include rogue mutants and organizations on par with SHIELD's capabilities, like Hydra.
When mutants became publicly known, Nick was ordered by the government not to get involved, but he disobeyed orders and indirectly assisted the X-Men and Brotherhood in freeing their comrades from Area 51, including his old friend Logan.
With the appearance of X23, who broke into one of the SHIELD's compounds and stole their data on the X-Men, Fury again broke the rules by allowing X23 to run rogue after Logan apprehended her and set her free at the Xavier Mansion. Though since she no longer was a Hydra operative, she was likely to be no further threat. X23 and Wolverine was also largely responsible for allowing SHIELD to capture most of those in Hydra, including Omega Red.
Fury, under orders, eventually released Trask into his custody so the scientist could continue working on his sentinel project. They wanted to be ready for whatever Apocalypse had planned for the world, but even the new Sentinels were no match for Apocalypse's horsemen, and thus Fury had to rely on the help of the X-Men and the mutant Leech to save the world.
