VIDEO : Lex Luthor To Join 'Supergirl'

Television today announced a Supergirl announcement that will rock the Arrowverse almost as much: Lex Luthor is coming. Superman's greatest nemesis will come to Supergirl sometime after the crossover; he has not yet even been cast, and will not appear in the event. ?We?re beyond excited to introduce iconic villain, Lex Luthor, to Supergirl and to weave him into our story this season,? Executive Producers Robert Rovner and Jessica Queller said in a statement.? This means that the Arrowverse take on Luthor will come to TV just weeks after the first appearance of the shared superhero universe's first look at Lois Lane.
