Johann Schmidt was a Nazi general officer and confidant of Adolf Hitler. He has been closely affiliated with HYDRA and is an enemy of S.H.I.E.L.D., the Avengers, and the interests of the United States and the free world in general. He was physically augmented by having his mind placed into the body of a clone of Captain America, the pinnacle of human perfection. He has been seemingly killed in the past, only to return time and time again to plague the world with schemes of world domination and genocide.
