Max Fury is a renegade Nick Fury LMD and a member of the Zodiac.
In the early 2000s, Scorpio stole an advanced S.H.I.E.L.D. Life-Model Decoy of his brother Nick Fury and used the Zodiac Key to reprogram it. Instantly, the LMD gained all of the real S.H.I.E.L.D. Executive Director's memories and actually thought it was the real thing.
Max served Scorpio in his mad scheme to create an andriod version of the Zodiac. He kidnapped Jack Norriss and helped Scorpio fight against the Defenders. When Scorpio realized that he was defeated he commanded Max to give him a gun and shot himself. It was later revealed that this Scorpio was, in fact, himself an LMD.
Later, When the LMD Zodiac was again taken down before their plan to use the LMD to free a prisoner from the Avengers came to fruition. S.H.I.E.L.D. determined the LMD to be an anomaly, as the Zodiac Key altered it so much that it began thinking for itself and had it held up on the Helicarrier for study. But the LMD repeatedly escaped S.H.I.E.L.D. custody and was constantly hunted and forgetting that it wasn't the real thing. In the meantime, the LMD was taking down Hydra, A.I.M. and U.L.T.I.M.A.T.U.M. plots.
When S.H.I.E.L.D. finally caught him, the LMD came face-to-face with the real Fury, who determined that he has to be destroyed, for the LMD having all his memories made him too dangerous. But John Steele helped the LMD escape by replacing him with another. He convinced the LMD, who he dubbed Max, to join the enigmatic Shadow Council.
He tried to wield the power of a tri-crown, which the Shadow Council collected using a new version of the Masters of Evil, to unleash the power of the Abyss and mental-control the world, but because he was a robot, he couldn't use it. Taskmaster managed to take the crown from him and use it for his own purposes, until he was stopped by Venom of the Secret Avengers. Max Fury was then taken to the Secret Avengers' HQ, the Lighthouse, and freed by Black Ant, member of the Descendants. After accepting to join his team of robots and cyborgs, Max Fury was killed by Black Ant for no apparent reason.
