Supergirl

In the series premiere episode, Superman’s cousin, Kara Zor-El – after 12 years of keeping her powers a secret on Earth – decides to finally embrace her superhuman abilities and become the hero she was always meant to be.

When Kara’s attempts to help National City don’t go according to plan, she must put aside the doubts that she – and the city’s media – has about her abilities in order to capture an escapee fro the Kryptonian prison, Fort Rozz. Also, Cat pressures James to use his connection to Superman to get her an interview with Supergirl.

Supergirl’s powers are tested when Reactron (guest star CHRIS BROWNING), one of Superman’s formidable enemies, arrives in National City and targets the young hero. Also, Cat plans to run an expose on Supergirl.

Kara’s Thanksgiving may be ruined when she suspects her foster mother, Dr. Eliza Danvers (special guest star HELEN SLATER), who is coming to town, disapproves of her new role as a super hero. Also, when an accident transforms a volatile CatCo employee into the villainous Livewire, she targets Cat Grant and Supergirl. BRIT MORGAN guest stars as Leslie Willis/Livewire.

Kara’s two identities are stretched thin when Supergirl must protect National City from a series of bombings and Kara is tasked with babysitting Cat’s son, Carter (guest star LEVI MILLER). Also, James is conflicted when his ex-girlfriend Lucy Lane (recurring guest star JENNA DEWAN TATUM) seeks to rekindle their relationship.

Personal and professional stress get the better of Kara when she goes too far during a training exercise against Red Tornado, a military cyborg commissioned by Lucy Lane’s father, General Sam Lane (guest star GLENN MORSHOWER). Also, Cat’s tough exterior is shaken by a visit from her judgmental mother, Katherine (guest star JOAN JULIET BUCK), and Alex enlists Winn to look into her father’s mysterious death. IDDO GOLDBERG guest stars as Red Tornado and its creator, Dr. T.O. Morrow.

Kara and her friends must rely on their inner strength and courage when an earthquake strikes National City. Also, Alex’s mistrust of Hank reaches a breaking point when the earthquake traps them in the DEO with Jemm (guest star CHARLES HALFORD), a powerful alien escapee.

Kara goes toe-to-toe with Astra (recurring guest star LAURA BENANTI) when her aunt challenges Kara’s beliefs about her mother. Also, Cat is threatened with being removed as the CEO of CatCo after a hacker exposes her private and damaging emails.

With Astra in captivity at the DEO, her husband, Non (recurring guest star CHRIS VANCE), captures Hank, leading to a tense standoff between the two sides. Also, Kara continues to refute Cat’s allegations that she is Supergirl.

Kara does her best to support Winn when his father, the supervillain Toyman, breaks out of prison and seeks out his son for unknown reasons. Also, Cat offers Lucy a job at CatCo, and Alex asks Hank to use his powers to help uncover Maxwell Lord’s plans. HENRY CZERNY guest stars as Winslow Schott, Sr., aka Toyman.

Kara must help Hank face his painful past when a White Martian – a member of the alien race that wiped out his people – kidnaps Senator Miranda Crane (guest star TAWNY CYPRESS), an anti-alien politician. Also, Cat’s estranged son, Adam (guest star BLAKE JENNER), arrives in National City.

Kara faces off against her mirror image when Bizarro (guest star HOPE LAUREN), a twisted version of Supergirl, sets out to destroy her. Also, Kara grows closer with Cat’s son, Adam.

Kara’s friends must find a way to save her life when a parasitic alien attaches itself to her and traps her in a dream world where her family is alive and her home planet was never destroyed. Also, Alex, Hank and the DEO must fend off a Kryptonian attack while Kara is out of commission.

Supergirl does battle with the deadly Master Jailer (guest star JEFF BRANSON), who is hunting and executing escaped Fort Rozz prisoners. Also, Cat hires a second assistant, Siobhan Smythe (recurring guest star ITALIA RICCI), who immediately tries to one-up Kara. Meanwhile, James and Kara disagree over the DEO’s methods.

While James’s relationship with Lucy reaches a crossroads, Kara travels to Superman’s Fortress of Solitude in hopes of learning how to defeat Indigo (guest star LAURA VANDERVOORT), a dangerous being with a connection to Kara’s past, who can transport via the Internet.

After being exposed to Red Kryptonite, making her malicious and dangerous, Kara turns on her friends and the citizens of National City. Also, Cat appears on The Talk to discuss Supergirl.

J’onn J’onzz reveals the details of meeting Kara and Alex’s father, Dr. Jeremiah Danvers, and assuming Hank Henshaw’s identity. Also, Kara debates trusting someone new with her secret identity, while Siobhan (guest star ITALIA RICCI) plots against Kara.

Supergirl gains a new ally when the lightning-fast super hero The Flash (guest star GRANT GUSTIN) suddenly crosses over from an alternate universe and offers to help Kara battle Silver Banshee (aka Siobhan) and Livewire in exchange for her help in finding a way to return him home.

Kara must find a way to free her friends when Non and Indigo use mind control to turn National City’s citizens into their own army.

In the first season finale, Supergirl faces her greatest test yet when Non and Indigo plan to destroy every person on the planet – forcing Kara to do battle with an unexpected foe and risk everything…including her life.
