Arnim Zola

 A genius scientist and the world’s first genetic engineer, Arnim Zola performed countless experiments in horror and eventually gained the attention of HYDRA. Making his own body into an engineered creation which he can transfer his mind into and out of, Zola is effectively immortal as well as immoral, and a constant threat to the safety and security of the world itself. Arnim Zola is a HYDRA scientist, who claims to be the foremost authority on genetics in the world.  He has been working for HYDRA, and specificially Baron Zemo, since the 1940's.  Some time after World War II, Arnim Zola made "improvements" to his own body.
