With Guardian and Mon-El on the scene, Martian Manhunter has been a little sidelined lately on Supergirl. That’s all about to change, though, and a new poster is here to get us ready.

This week’s episode is all about the return of Livewire, so don’t expect a lot of Martian Manhunter there, but next week is a very strong episode for J’onn J’onzz. Titled ‘The Martian Chronicles,’ the episode will see a contingent of White Martians coming to Earth to Miss Martian back to Mars to stand trial. Obviously, it will be up to J’onn and Kara to stop them.

Worlds Clash. Heroes Unite.

Actor David Harewood actually shared the poster for the episode himself on Instagram. It features Martian Manhunter and Supergirl staring menacingly outward while a barrage of debris surrounds them. The tagline “Worlds Clash. Heroes Unite.” runs beneath them.

The Martian Chronicles. Coming soon.

The Martian Synopsis

Here’s the official synopsis for ‘The Martian Chronicles’:

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. However, when it is revealed that Armek shape-shifted into M’gann and is now loose in the building, the team realize he could be disguised as any one of them.

Supergirl airs Monday nights at 8/7c on The CW. ‘The Martian Chronicles’ will air next Monday, February 6.
