Those of us who caught the teaser at the end of the last episode had a pretty good idea that somebody looking an awful lot like Hank would be attacking Kara in the near future; DC Entertainment confirmed speculation that the Supergirl version of Cyborg Superman would indeed be Hank Henshaw.
From the looks of things, Supergirl Season 2 will take the ambiguity out of original Hank’s fate.
Kara will run into Cyborg Superman on her mission to rescue Mon-El from Cadmus, and she’ll discover that the scientists of Cadmus recovered the real Hank Henshaw’s body and used their technology to turn him into something else entirely.
