Since it seems like the Defenders will be dealing with whatever that big hole in the ground the Hand was making in the second season of Marvel's Daredevil… it should come as no surprise that Elodie Yung has been added to the cast of Marvel's The Defenders as Elektra… who we last saw as a corpse in the possession of the Hand and in a sarcophagus.
I the comics, Elektra dies and is resurrected by the hand but only after Matt Murdock tried to bring her back. His attempt failed to save her but it clarified her soul… not exactly sure how that worked, but she came back as a good guy.
The cast of Marvel's The Defenders continues to grow having added a bunch of characters already introduced in other Netflix series. Other than Sigourney Weaver, no new actors have been announced and her character still remains a mystery.
