Supergirl: Teri Hatcher Debuts in New Clip

Beam me up, Teri Hatcher! The "Lois & Clark" star will make her "Supergirl" debut in "Star-Crossed," tonight's episode. In a new clip, Hatcher's character -- described as "a new villain" in the episode synopsis -- introduces herself to Kara, but seems much more interested in Mon-El.

The clip opens with a tense sense between Mon-El and Supergirl, where Mon-El offers to be transported onto a mysterious ship in Supergirl's place. Mon-El insists he'll be fine, though Supergirl's worry is evident. So, just as Mon-El is about to be teleported on board, she super speeds into his arms. As such, they're both brought up to the ship -- and Mon-El is none too pleased about it.

Now on board, Mon-El and Supergirl are confronted with a dozen hooded figures. Supergirl immediately goes on the defensive, but is surprised when they all begin to kneel. Confused, she asks Mon-El why they're bowing, only for two unmasked characters -- played by Hatcher and "Hercules" star Kevin Sorbo -- to call out Mon-El's name. The clip ends before Mon-El or Kara are offered the chance to react to it.
