10 Comic Book Villains That Need To Be In Agents Of S.H.I.E.L.D.

4. Dr. Faustus

Who Is He: Dr. Johann Fennhoff is one of the most gifted psychiatrists in the Marvel Universe. Unfortunately for our heroes and S.H.I.E.L.D. agents, his specialty is brainwashing and mind manipulation. In the comics, he is responsible for controlling Sharon Carter and forcing her to assassinate Captain America. How He Could Fit Into The Show: Having just lost one of their best brainwashers (Whitehall), HYDRA could be looking to recruit another mind control expert. Enter Doctor Faustus. While his name will probably just be mentioned in passing (as an easter egg to fans), it would be very interesting to see what he could do if he captured a member of the team (or became one of their psychiatrist - looking at you Fitz).
