Sara Grey

Played by Olivia Booth-Ford

Sara Grey is Jean Grey's older sister, a fellow telepath who was secretly abducted and experimented on by the Department of Damage Control. She dies in the agency's custody before the events of the film, and the DODC's cover-up of her death is what drives Jean's search through its facilities. Her fate, once uncovered, is the reason Jean's rampage stops being about revenge and becomes something Spider-Man can actually answer.

First turns up in Spider-Man: Brand New Day.
