Earlier tonight, Supergirl finally made its midseason premiere with 'Supergirl Lives,' an episode directed by renowned DC fanboy Kevin Smith. The CW show joined DCEU companions Legends of Tomorrow, Arrow, and The Flash on the network last year after a move from CBS, and has gained many fans in recent months. Supergirl, aka Kara Zor-El/Danvers, recently teamed up with her fellow heroes for a major crossover event which became one of The CW's most-watched events ever.

The series returned to the airwaves with its trademark heart, as fans found Kara at the center of an inhumane alien operation and her sister Alex struggling to balance life and love. While the episode ended by teasing some potential trouble for a recurring character, it looks like Kara and co. will have bigger things to worry about next week -- namely, one of Ms. Zor-El's most notorious enemies, Livewire.

A promo for next week's episode of Supergirl, titled 'We Can Be Heroes,' reveals that the villain Livewire is back on the show for a third time. Check out the full teaser, above.

We last saw Livewire back in season 1, when belligerent CatCo employee Leslie Willis transformed into the villain after a horrible accident and sought vengeance against Cat Grant. She then reappeared later in the season in an attempt to mentor fellow villain Banshee, with both facing off against Supergirl and The Flash in their first crossover episode. At the conclusion of that episode, Barry constructed metahuman-proof containment units, which is where Livewire has been all these months, but it looks like she's found a way out.

Livewire is a compelling villain, especially given her ability to literally become a part of technology, which made her a big problem for media conglomerate CatCo during her debut. Livewire's only real weakness is water, making her a formidable foe, but it's unclear if she's a character compelling enough to earn three turns on the show. Though Supergirl has gotten into the habit of recycling its villains (since Kara is too good to kill most of them), three appearances in two years is a lot.

No matter what, Supergirl is bound to keep fans hanging on with its lovable characters and Buffy-esque endearing corniness. It's just a matter of Berlanti and friends making sure we don't see certain characters too much.
