SUPERGIRL Squares Off Against Agent Liberty & Mercy Graves In An Action-Packed New Season 4 Trailer

SUPERGIRL Squares Off Against Agent Liberty & Mercy Graves In An Action-Packed New Season 4 Trailer

With Supergirl returning this Sunday, The CW has released an action-packed new trailer featuring some of the early season action as Kara faces off against both Mercy Graves and Agent Liberty.

Supergirl is going to have her hands full this season with a pair of new human baddies that may arguably be more dangerous than any of the aliens she's faced in seasons past: Agent Liberty (Sam Witwer) and Mercy Graves (Rhona Mitra). The pair will have a very anti-alien agenda throughout the coming year and are looking to use fear to divide the country and turn it against Kara (Melissa Benoist) and the people she's sworn to protect, human and alien alike. 

There's also a Kara doppelgänger still-at-large and while the series has chosen to keep her costume under lock-and-key for now, it shouldn't be too long before we catch a glimpse at the potential real big bad of season four. 



"American Alien" - (8:00-9:00 p.m. ET) (TV-PG, V) (HDTV)

HOPE VS. FEAR - Diving back into reporting, Kara (Melissa Benoist) welcomes a new cub reporter to CatCo. Meanwhile, James (Mehcad Brooks) and Lena (Katie McGrath) argue about James' impending indictment for acting as the vigilante Guardian, while Alex (Chyler Leigh) and Brainy (Jesse Rath) struggle to get in sync at the DEO. Supergirl (Melissa Benoist) is called into action when remnants of the anti-alien terrorist organization Cadmus try to assassinate pro-alien leaders, but their endgame turns out to be much more sinister than she expected. J'onn (David Harewood) relishes his peaceful new life, but an outing with an old friend causes him concern. Jesse Warn directed the episode with story by Robert Rovner & Jessica Queller and teleplay by Gabriel Llanas & Aadrita Mukerji (#401). Original airdate 10/14/2018

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.
