Secret Warriors is an alias for the fictional group Team White created by Nick Fury, a team of superpowered agents appearing in American comic books published by Marvel Comics. The name "secret warriors" also refers to the members of other hidden groups in the comics series Secret Warriors and its related titles. Team White was the main team led by Nick Fury from 2009 to 2011. First appearance was in "The Mighty Avengers" #13 (July 2008).

Created by Brian Michael Bendis and Alex Maleev, the characters were introduced in Mighty Avengers #13, and debuted as a team in Secret Invasion #3, both published in 2008.

The team was introduced in the Secret Invasion tie-in issues of Mighty Avengers and then featured in their own ongoing series. This series was co-plotted by Bendis with Jonathan Hickman writing. and was one of the titles launching as part of the Dark Reign storyline. The series was promoted by a series of passwords and clues given in solicitations for upcoming issues. A Marvel spokesman stated that further passwords would be released for the website later on.

The Team White entered battle for the first time during the Skrulls' invasion of Earth. Manhattan became a warzone with Super-Skrulls devastating the city. The arrival of the Nick Fury-led team turned the tide of battle enough to rescue the combined forces of the Initiative and the Young Avengers from being killed by the Skrulls. Fury rallied all the other heroes together with his agents and began a series of hit and run attacks on the Skrull forces throughout the city. It took all of them just to take out a few Super Skrulls at a time. A better chance at defeating the Skrull invasion came at the sight of Thor's lightning calling them all to Central Park. There, the team gathered with all of the other assembled heroes and repelled the Skrull invasion. In the immediate aftermath of the heroes' victory, Fury and his agents quickly took their leave and went back underground.

During the Dark Reign storyline and the Nick Fury, Agent of Nothing arc, Nick Fury revealed his true agenda to the team. Hydra was bigger and more far reaching than he ever realized. It even had its tentacles in S.H.I.E.L.D. while he ran it. However, the Skrull attack and the dismantling of S.H.I.E.L.D. hit Hydra hard, giving Fury an opportunity to prepare for a new war against them while they reorganized.

With S.H.I.E.L.D. being replaced by H.A.M.M.E.R., Hydra was moving to claim as many assets as it could before the U.S. government could, and the agents knew that Hydra would go after the Red Worm psy-ops facility next. The team needed to get there first to prevent Hydra from claiming such an asset. Hydra moved too quickly and the team arrived to witness Kraken and Gorgon personally overseeing the facility's evacuation. When they were in the process of executing two telepaths who were brain damaged by the rushed process of being awakened, Daisy Johnson ordered her team to move in. Kraken teleported away with the remaining telepaths, and Gorgon stayed behind to fight. He severely wounded Yo-Yo by chopping off both of her hands.

Johnson traveled to the Australian outback along with Druid to meet with Eden Fesi, who was another name on Fury's list of Caterpillars. He readily agreed to join, with Gateway's permission. Fury reached out to Dum-Dum Dugan for help. Dugan and many former S.H.I.E.L.D. agents had gone private in the wake of H.A.M.M.E.R.'s takeover and formed a Howling Commandos private military company.

Fury led the Howling Commandos on a raid of the Dock, another former S.H.I.E.L.D. base that housed the helicarriers. While the Howling Commandos and H.A.M.M.E.R. fought, Hydra intervened to prevent Fury from taking the helicarriers. Team White arrived to back Fury up and turn the tide, making the raid on the Dock a success. Hydra forces retreated, the Howling Commandos made off with three helicarriers, and Fury recruited 3,000 H.A.M.M.E.R. agents over to his side.
