The Supreme Hydra (also called the Hydra Supreme) is a term given to the leader of Hydra. At other times, the title has also been used to refer to the leaders of various Hydra branches and splinter groups. Besides Baron Strucker, among the known Supreme Hydras in order of appearance are:
Arnold Brown - The Imperial Hydra who was the organization's figurehead.[6]

In order to expand the enterprise of Captain America, Baron Helmut Zemo decided to create an even bigger team of villains by recruiting several long term solo villains and reforming the Circus of Crime, the Masters of Evil, the Wrecking Crew, and the Serpent Solutions altogether into one group as part of Hydra's rise to power. As a result, he forms the Army of Evil.[13] The Army of Evil first appeared where they attacked Manhattan in retaliation for what happened at Pleasant Hill. They fought the Defenders, Doctor Strange, Cloak and Dagger, and Spider-Woman before being withdrawn so that Manhattan can be covered in a Darkforce dome which trapped the heroes present.[14] Then they attacked Washington DC so that Hydra can secure the capital to complete Hydra's takeover of the United States.[15] The Army of Evil was kept in stasis pods until Hydra Supreme gave orders to awaken them so that they can help Hydra fight the heroes. Before Baron Zemo can complete the job, he is thwarted by Black Panther and Winter Soldier.[16]
Among the known members are:
Absorbing Man - A supervillain who can absorb the properties of any matter.[13]

In the Marvel Cinematic Universe, Hydra was founded in ancient times, formerly as a cult centered around the fanatical worship of Hive, a powerful Inhuman that was exiled to the planet Maveth by ancient Inhumans. Over the centuries in Captain America: The First Avenger, the cult evolved, taking many forms, with its most recent incarnation coming into existence shortly after the rise of Nazism in Germany under the leadership of Johann Schmidt as the scientific branch of the Nazi Schutzstaffel. However, as revealed in Captain America: The Winter Soldier, Hydra was secretly rebuilt inside S.H.I.E.L.D. by Schmidt's top scientist Arnim Zola, who was recruited into the agency during Operation: Paperclip. When Hydra emerges, S.H.I.E.L.D. is labeled as a terrorist organization while most of its non-Hydra members leave S.H.I.E.L.D. to work the private sector or go off the grid in the second season of the television series Agents of S.H.I.E.L.D..
