Supergirl Trailer Teases Return of Livewire and Dominators

Heroes and villains have descended on National City at an astonishing rate. First, there were those aliens. Then, there were … those other aliens. And now there's a pale lady with a laser whip, again? Clearly, this is a job for Supergirl and company.

Fortunately, a new trailer for The CW's "Supergirl" marks the return of the heroine for the second half of Season Two with the Kevin Smith-directed "Supergirl Lives," which sees Kara Danvers, played by Melissa Benoist, and Mon-El, portrayed by Chris Wood, traveling to another world to break up an alien slaver's ring.

Kara (Melissa Benoist) is moved by the story of a missing woman named Izzy (guest star Harley Quinn Smith) and decides to investigate despite Snapper Carr’s (guest star Ian Gomez) order to leave it alone. Kara takes Mon-El (Chris Wood) with her to the last place Izzy was seen and the duo find themselves thrust through a portal to another planet, Slaver’s Moon, where the downtrodden are sold as slaves. The leader of the trafficking ring is none other than Roulette (guest star Dichen Lachman). To make matters worse, Slaver’s Moon has a red sun, which means Kara and Mon-El are stripped of their powers and stuck on the planet with no way home. Meanwhile, back on Earth, Alex (Chyler Leigh) blames herself for Kara’s disappearance, fearing she’s become too focused on her new relationship with Maggie (guest star Floriana Lima) and too complacent in watching out for her sister.

The trailer also teases bigger events down the road. Long-running "Superman" villainess Livewire, played by Brit Morgan, will make her return, and it looks as if greater emphasis will be placed on Jimmy Olsen's (Mechad Brooks) costume identity Guardian.

Returning Monday, Jan. 23, at 8 p.m. ET/PT on The CW, "Supergirl" stars Melissa Benoist, Mehcad Brooks, Chyler Leigh, Jeremy Jordan, David Harewood and Chris Wood.
