Supergirl: Livewire Preview Released

Following a reshuffling of episodes, CBS has released a preview of tomorrow night's Supergirl episode, titled "Livewire."

The episode will guest-star Supergirl movie actress Helen Slater, who plays Kara's adoptive mother Eliza Danvers, along with Brit Morgan as the titular villain Livewire.

The promo appears to feature footage from more than one episode, as it also shows off Kara fighting both Red Tornado (expected to appear in the forthcoming episode "Red Faced") and an as-yet-unidentified alien. There's also a line that "you don't need powers to be a hero." Since it's directed at Kara by James Olsen, that line may come from a forthcoming episode rumored to be titled "Human For a Day."

You can check it out below.

Kara's Thanksgiving may be ruined when she suspects her foster mother, Dr. Danvers (Helen Slater), who is coming to town, disapproves of her new role as a superhero. Also, when an accident transforms a volatile CatCo employee into the villainous Livewire, she targets Cat and Supergirl.

Brit Morgan guest stars as Leslie Willis/Livewire and former Supergirl Helen Slater guest stars as Dr. Eliza Danvers, Kara's foster mother. Check out two preview images, featuring both guest stars, in our gallery below.

"Livewire" episode of Supergirl will air Monday, November 16 at 8:00 PM on CBS.
