Nick Fury is the director of S.H.I.E.L.D.. He grew up in Hell's Kitchen.
During World War 2, Fury was a sergeant leading an unit known as the Howling Commandos. The Commandos' most frequent enemy was Nazi Baron Strucker. The Howling Commandos also worked alongside Captain America sometimes. At some unknown point after Cap's freezing, Nick lost an eye.
Nick was the guinea pig for a formula to extend his life, so even though he has gotten some white hair, he is still in almost prime condition in the present day.
Fury has faked his death several times thanks to duplicate robots called Life Model Decoys.
