Supergirl: Here's Your First Look at Miss Martian

Near the end of tonight's episode of Supergirl, Martian Manhunter went into a bar -- and what he found there surprised even him.

Coming right at the end of the clip posted above, the bartender Hank creepily followed out into a dark alley reveales herself as M'gann M'orzz, the "last daughter of Mars."

The character, a major player in Geoff Johns's run on Teen Titans, is probably best known to TV audiences from her appearances on the animated cult hit Young Justice.

She's played here by Sharon Leal, who has a number of notable credits to her name, including multi-episode arcs on Private Practice, Hellcats, and Grimm.

M'gann is actually a White Martian who decided to become "good" and elected to look like a Green Martian instead. The concept of White Martians was introduced in the eleventh episode of Supergirl's first season, when Martian Manhunter had to face one down.

There had been some speculation that due to the on-again, off-again Titans series that Warner Bros. Television was trying to develop, Miss Martian may have been off the table for Supergirl. At this point, that show looks like it won't happen.

Supergirl hasn't been shy about drawing from Teen Titans and other fairly recent material like the "World of New Krypton" arc in the Superman titles from about ten years ago, so it wouldn't be surprising to learn that Miss Martian first showed up as an operative for the White Martians before being turned on Supergirl.

The character will play a bigger role on next week's "Survivors," an episode that centers on an underground fight club for aliens run by Justice Society villain Roulette. You can see a trailer for that episode here.

Supergirl airs Monday nights at 8 p.m. ET/PT on The CW.
