Ladies and gentlemen: Ms. Nicolette ‘Nic’ J. Fury.
Nic has a long history of spy-work, dating back to the early days of S.H.I.E.L.D. She moved up the ranks as a high-level Special Forces officer, before moving more and more toward espionage, eventually joining S.H.I.E.L.D. in the mid 1960s. She became the agency’s Director at the request of longtime friend Alexendra Pierce (who was later revealed to be not only definitely not a friend, but a mass-murderer and a traitor as well). Nic takes her work VERY seriously, and does little else with her time. She is a hardass, a badass, and she gets her job done, however she has to. She’s always one step ahead, thinking the long game, and ready to put herself on the line if it protects the greater good.
While Nic usually operates within the protocols of S.H.I.E.L.D., she will do what she feels is right regardless of what the higher-ups might have to say about it. (See her interactions with the World Security Council during the Battle of New York, and her assisted take-down of S.H.I.E.L.D. with Captain America, once HYDRA’s infestation of it was revealed.)
And, while she still expects just as much out of her operatives as she herself puts in, Nic is still reluctantly close to many of her people, including Marcus Hill (her second in command), Christine Rogers, and Nathaniel Romanoff ((the Black Widow) – shown below having just used the Widow’s Bite on himself to short-circuit the booby-trapped badge he’s wearing)).
She rarely openly shows affection to her operatives, but she will defend them to the best of her ability, and she does her utmost to see to it that they keep breathing for the foreseeable future. Trust is not something she does voluntarily, even with those closest to her. She is known to have entrusted a critical flash-drive to Rogers during the Project Insight disaster, but otherwise plays everything very, VERY close to her chest.
Be glad she’s on our side.
