| Wikipedic | HYDRA is a fictional terrorist organization in the Marvel Universe. In its original continuity, it was headed by nondescript businessman Arnold Brown, who was killed as S.H.I.E.L.D. apparently crushed the organization. It soon returned, however, headed by Baron Wolfgang von Strucker, under the aegis of the Nazi Red Skull; HYDRA's changing origin was one the earliest Marvel retcons. After its initial defeat, several of its branches surfaced, appearing to be unrelated and independent. HYDRA's scientific branch was initially A.I.M. (Advanced Idea Mechanics), which later split off into its own organization. Other factions included THEM and the Secret Empire. (references) | ||
