In the Age of Apocalypse alternative setting, Bruce Banner was never exposed to gamma radiation. Therefore, he did not become the Hulk. Instead he became a member of the Human High Council, where he was a scientist and became a weapons designer. However he also yearns to gain knowledge and power, something Apocalypse was willing to help with, and so Bruce sold himself to Mikhail Rasputin, one of the Horsemen of Apocalypse, to give him mutants as test subjects. He succeeds in his experiments and can now transform into a creature resembling the Grey Hulk. He was used as a mole in the council, but was discovered by Susan Storm and Ben Grimm because the patterns of Bruce's injuries were identical to those sustained by the Hulk.
