While we don’t know too much about Reign yet, Supergirl executive producer Alex Kreisberg is promising that she won’t be like any other comic TV villain.
In true genre TV tradition, Season 3 of Supergirl will have an all-new season-long villain terrorizing Supergirl and the D.E.O. That villain is Reign, who was teased in the Season 2 cliffhanger as another baby being who survived the destruction of Krypton.
As opposed to being the big bad right out of the premiere’s gate, viewers will actually watch Reign become more villainous over the course of the season.
