Josef Dragovich (Earth-1705)

Josef Dragovich was a Soviet scientist who defected from his nation after sympathizing with the Axis belief after his researchs on his creation, the Fear Toxin, were branded too dangerous. Joining Baron Kerr in his Hydra division of the Nazi Empire, Dragovich, under the moniker of Scarecrow, developed multiple technologies and chemical weapons (which were evolved from his Fear Toxin) for Johann and his army. When Kerr turned into the Joker duo to the interference of American superhero Batman, Scarecrow continued to serve him out of fear for his life, and aided his master into his attempt to bring chaos to the world.

After both the Joker and Batman seemingly died during a final showdown in the Artic, Scarecrow was captured by the US and their SSR, cooperating with America in their efforts against his own country. Josef, however, had darker plans, and from scratch he secretly rebuilt Hydra with the aid of Baron Freeze and Poison Ivy. Following his death, Scarecrow uploaded his counciousness into a software program called Ultron, leading Hydra from anywhere he wants.
