Supergirl only just got done fending off an alien invasion as part of The CW’s big DCEU crossover, but back in her own universe Earth has once again found itself under attack by extraterrestrial villains. The wicked White Martians have targeted Earth, following the outing of M’Gann M’orzz (aka “Miss Martian”) as a traitor of their own race.

The impending episode, titled “The Martian Chronicles” (a reference to the classic science fiction novel series by Isaac Asimov) picks up in the wake of J’onn J’onzz having released Miss Martian from her captivity at the DEO Base after determining that she was indeed telling the truth about having betrayed the other White Martians; who were responsible for the genocide of his Green Martian species centuries earlier. Though hiding on Earth in the guise of a Green Martian herself, M’orzz “outing” has drawn the White Martians back to Earth to imprison her as a traitor.

Courtesy of he CW comes a new clip (see above) featuring Miss Martian, Martian Manhunter and Supergirl herself fending off the first wave of the invasion force. The CW also released these new stills from the same episode:

A frequent source of outer-space villainy in various DC Comics stories, White Martians previously appeared as a threat in Supergirl’s first season but remained dormant for Season 2 until the reveal of Miss Martian’s true identity. Standing several feet taller than most other humanoid characters and possessed of superhuman strength comparable (but not equal) to Supergirl’s own, they remain some of the most fearsome recurring nemesis in The CW’s so-called “Arrowverse” DC Extended Universe series.

The official synopsis for the episode (in part) describes the situation:

WHITE MARTIANS ATTACK THE DEO — Armek (guest star Terrell Tilford), a White Martian, descends on National City intent on taking M’gann (guest star Sharon Leal) back to Mars to face her punishment as a traitor. Hank (David Harewood) and Supergirl (Melissa Benoist) determine the best way to keep M’gann safe is to bring her to the DEO.

While not shown in the clip itself, it’s expected that the presence of another enemy alien faction on Earth with also tie in to Supergirl’s ongoing subplots concerning the Daxamite refugee Mon-El, who recently reveal his romantic intentions toward Kara (which were rebuffed) and his related intentions to become a superhero in his own right (which were not.) During a recent episode’s excursion to an alien world, Mon-El was recognized and ordered pursued (but not harmed) by several alien interlopers – suggesting that there are secrets to his backstory still yet to be revealed (many fans believe that he is actually the former prince of his planet, rather than a bodyguard as he originally claimed.)

Supergirl: Season 2 – The Martian Chronicles will air Monday, February 6 on The CW.
