The Supergirl Season 4 Trailer Is Here!

A trailer for the upcoming fourth season of Supergirl was released today during the show’s panel at the Comic-Con International in San Diego. There are a lot of new threats coming, including the ominous Agent Liberty (Sam Witwer!)

You can see the trailer below. Supergirl Season 4 premieres Sunday, October 14 on The CW.

Season three saw Supergirl stop Reign and the other Worldkillers’ threat to humanity and our planet, and in the process, Kara was shocked to find her mother Alura alive and living in a salvaged Argo City that survived the destruction of Krypton. Reconnecting with her past caused Kara to realize that her true home is now here on Earth, where big changes are taking place for her and all of her friends in National City – and also, it appears, for a doppelganger in Russia! Season four promises to be full of surprises, action, adventure and lots of big revelations for Supergirl, Alex, James, J’onn, Lena and Brainy.
