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

6. Sin

Who Is She: Sinthea Schmidt is the daughter of the Red Skull. She has a long history of working with and for HYDRA (like father, like daughter). Indoctrinated from an early age as a HYDRA devotee, she has turned herself into a living weapon with deadly fighting skills and tactics. How She Could Fit Into The Show: Avoiding her complicated (and often confusing) backstory would be a must. Because the show takes place in modern times, she would either have to be a daughter created from his DNA or a female clone. With HYDRA always looking at both technology and at their fallen leader, she could be created in a flashback (about 20 years), maybe even raised by Garret. With her deadly fighting skills and a genetic connection to one of the great villains of the MCU, she could serve as a strong tie to the films while being a fierce threat to S.H.I.E.L.D. on her own.
