World War II
HYDRA was founded as a branch of Nazi military at some point before World War II. The scientists of HYDRA were involved in creating new advanced weaponry for the Axis powers. The best known leader of HYDRA at the time was Baron Zemo.
When the war broke out, the soldiers of HYDRA, commanded by the infamous Red Skull, were present on all battlefields of Europe. They managed to conquer much of the European continent. However, the Allies, led by the USA, decided to strike back, forcing the armies of the Axis to retreat.
In 1943, the Allied super soldier, Captain America, had a confrontation with Baron Zemo in Italy, during which Zemo's latest weapon, Virus X, was drenched upon Zemo, adhering his mask right to his face permanently and infecting his vital bodily systems. Some time later, Captain America and Bucky prevented Red Skull from opening Bifrost Bridge, which Skull intended to use to bring the army of mythological creatures from Asgard to use them against the Allied Forces. During the battle, Red Skull disappeared, and Captain America ended up frozen in ice.
Despite the defeat of the Axis in 1945, HYDRA continued to exist. The organization was later taken over by Skull's former lieutenant, Wolfgang von Strucker, who lost his right arm and got a new cybernetic arm that absorbs the youth of anyone who came in physical contact with him.
On the present day, HYDRA is still bent on its goal of taking over the world even after their defeat during WWII. They obtained new weapons and tech from A.I.M. who took Stark International technologies to improve their forces and tech, which angered Iron Man. HYDRA had maintained a number of secret facilities around the globe far beyond S.H.I.E.L.D.'s watchful eye. HYDRA's headquarters were on an island of unknown coordinates. They even have relations with the Maggia, Yushida Clan and the Russian underworld as they respected and fear HYDRA's growing power.
HYDRA had hired A.I.M. to create the Cosmic Cube for Baron Strucker in his desire to have the world remade in his image. But M.O.D.O.C. had other plans and decided to keep the Cube for himself. His action had ignited a war between HYDRA and A.I.M. in and over New York City, which caused the Avengers and S.H.I.E.L.D. to intervene their armed conflict.
With all of HYDRA's and AIM's soldiers and leaders being captured, it is currently unknown if HYDRA still lives.
