29 Brand New Characters Coming To MCU Phase 4
7. Eleanor Bishop - Hawkeye
Similarly to The Falcon and the Winter Soldier, Hawkeye will seemingly feature several villains, but the clear choice for the role of main antagonist is Vera Farmiga's Eleanor Bishop. An actress of Farmiga's talents is a big gain for Marvel Studios, and it's unlikely she would be wasted on playing nothing more than Kate's mother.
In the comics, Eleanor was thought to be killed when her daughter was a small child, but it was later revealed that she had in fact been alive all this time, and working in partnership with Madame Masque, one of Kate's greatest rivals.
Since Kate will only be in training, a past relationship with any villains is unlikely with the exception of her mother, who will potentially return from the dead as something of a combination of both Eleanor and Madame Masque from the source material.
