Lex Luthor brainwashes half of the planet into loving him using the Obsidian Lens and gains the combined powers of the bottled Leviathan members, intending on doing what the Anti-Monitor couldn't do; destroy all life on Earth and beyond, save only for his brainwashed followers. With the help of her team, Kara Danvers destroys Gamemnae by uploading the Anti-Life Equation into the nearest console. In order to take down Lex's satellites, Kara falsely offers herself up to Lex at the Fortress of Solitude. Lex defeats Kara's friends and sends Kara to the Phantom Zone before being depowered and arrested. Meanwhile, J'onn J'onzz and M'gann M'orzz destroy the satellites. Afterward, Lillian Luthor visits Lex at the National City Prison, but Lena Luthor uses Myriad to wipe their memory of Supergirl's identity. As Acrata, Andrea Rojas secretly buys her father's shares in Obsidian in order to restore her company. J'onn and M'gann begin searching for people to aid them in rescuing Kara, including Jonn's brother Malefic, but to no avail.

Kara's friends find a benign vampire-like Transilvanian named Silas who once broke into the Phantom Zone, and they agree to work with him. However, due to the Crisis, the Zone fractured into an archipelago and they cannot locate Supergirl as easily. With Silas's help, Kara's friends open a portal to the Phantom Zone, but they are unable to travel through and several Phantoms escape.

In retaliation, Lex has Otis Graves destroy it and puts the blame on a project that Lena oversaw. Kelly Olsen helps Alex cope with her sister's disappearance, and Lena talks Brainiac 5 down from a plan to murder Lex. Lena later quits LuthorCorp.

At the same time, the poacher Professor Naxim Tork and his henchman Mitch arrive in a Bismolian ship to capture superpowered aliens for his menagerie. He plans to attract Kryptonians to a staged disaster. Kara and Dreamer use their powers to prevent the disaster, which Cat partially witnesses. She enlists a child with a small drone to investigate further. Kara resolves to break off with Kenny but then learns he has built her a "Fortress of Solitude."

Zor-El joins Supergirl in putting out a fire from a fallen satellite at a large collection of garbage in the ocean. The garbage prompts Zor-El to combat Earth's environmental crises out of guilt for failing Krypton, so he uses a Kelex named Oscar.

Afterwards, Zor-El leaves to reunite with Alura on Argo City, Kara talks to Alex about her time in the Phantom Zone, and Lena calls Nia saying that she interpreted her Fear Vision of the Kelpie and leaves to visit her birthplace.

Mitch first finds an Edifarian engineering expert, Dr. Desmond Raab, to build a cryo-bomb capable of freezing everything within a mile and uses it on the Ormfell Building, a housing project to which Orlando would be able to bring Joey. J'onn stabilizes the building and Supergirl destroys the bomb with her heat vision, but this inadvertently recharges Nyxly's powers. Supergirl tries to persuade the city to not let Councilwoman Rankin turn the Ormfell Building into a tech complex, and succeeds by letting Orlando tell his story to the city council.

As the Superfriends are preoccupied with finding Nyxly, Kelly and John Diggle work to identify Rankin's strange abilities. Kelly fights Rankin as Guardian and grabs a piece of her hair, allowing Brainy to learn how to stop her. He also improves the Guardian suit and tells Kelly that even the 31st century has inequality and oppression.

At the Fortress, Kara and Lena learn about the Totem of Courage from Vita, a simulation of an eccentric Kryptonian witch. When someone activates it with a magic word, they must revisit a time when they lacked courage, gaining its power when they succeed in this trial. Supergirl disrupts Nyxly's theft of the totem in the form of a slingshot that David used to slay Goliath and blasts it with her heat vision before Nyxly can escape, leaving Supergirl and Nyxly with half each. This event enhances the courage of everyone at the scene: a shy scientist is emboldened to harness lightning, Sentinel becomes reckless, J'onn is distracted by being able to express his feelings, and Brainy dares to make inaccurate predictions. Attempting the trial, Kara revisits her emergence as Supergirl, but fails, and Nyxly revisits her defeat by her father, finally succeeding by expressing her anger at her brother's betrayal. Kara's half of the totem tries to rejoin the other. Kara has Lena release it because she can only stop a catastrophic lightning storm with her team restored to their normal personalities. This works, but Nyxly now has the totem and looks for more. Vita suggests to Lena that a previously unknown Earth witch might be able to help.

Unable to kill a guard to obtain the Totem of Hope, Nyxly abandons the Totem of Humanity, ending the violence. Supergirl recovers it, but Nyxly starts off after the others while planning to reclaim the Totem of Humanity at a later date. Meanwhile, Kelly checks on the new foster parents of Esme, the girl from Joey's former group home. They seem nice. When they are trapped by the mob, they discover that Esme can breathe fire when faced with an Infernian attacker.

Esme's new life with Kelly and Alex is soon complicated by her Dryalian ability to acquire superpowers from anyone nearby.

Nyxly identifies the Totem of Hope, and find that in order to use it they must "inspire hope brighter than the sun". Thinking this a job for Supergirl, Nyxly plans to extort both the Hope and Humanity tokens by taking William hostage.

Supergirl disarms both nations, passing her test by inspiring hope, and with William's help rescues him and gets all three stones.

Elsewhere, Nyxly places the Dream Totem in the gauntlet, causing Lex to appear.

Cast notes

Production

Development

In January 2020, The CW renewed the series for a sixth season. ^[27] Jessica Queller and Robert Rovner return as the showrunners. ^[28] In September 2020, it was announced that it would be the final season, with a 20 episode order. ^[29]

Writing

The twelfth episode was written by Azie Tesfai and J. Holtham. This marks the first time in the Arrowverse that an actor (Tesfai) wrote an episode. ^[30] Like previous seasons, the season too is inspired by sociopolitical issues in the real world, especially in its second half. Queller said the theme of the season would be "power, and the abuse of power, and the limits of powers, and from without and within". Rovner said the Black Lives Matter movement was another influence on the season. ^[31] Melissa Benoist, who portrays Kara Danvers / Supergirl, said the season serves as a "self-exploration" for her character, "looking in the mirror and [contemplating] what her power means because it's almost limitless and it makes her so strong on Earth". ^[32]

Casting

Main cast members Melissa Benoist, Chyler Leigh, Katie McGrath, Jesse Rath, Nicole Maines, Azie Tesfai, Julie Gonzalo, Staz Nair and David Harewood will return as Kara Danvers / Supergirl, Alex Danvers, Lena Luthor, Querl Dox / Brainiac 5, Nia Nal / Dreamer, ^[33] Kelly Olsen, ^[30] Andrea Rojas, ^[34] William Dey, ^[35] and J'onn J'onzz / Martian Manhunter. ^[36] In December 2020, David Ramsey was revealed to be reprising his Arrow role of John Diggle in addition to directing at least one episode in the season. ^[24] In March 2021, Claude Knowlton and Jason Behr joined the cast in undisclosed recurring roles for the sixth season. ^[22] Knowlton's role turned out be Silas while Behr's role turned out to be Zor-El who was previously portrayed by Robert Gant in season one and season two. In the third episode, Peta Sergeant debuted as series regular as fifth-dimensional imp, Nyxly, who would serve as the season's main villain. ^[37]

Filming

Filming began on October 13, 2020. ^[38] It was initially scheduled to begin after Benoist returned from maternity leave, ^[39] but was later rescheduled to begin on September 28, 2020. ^[40] However, by September 29, filming was indefinitely delayed, because of delays in receiving COVID-19 test results for the cast and crew, ^{[41] [42]} before beginning in October. ^[38] The early filming of the season worked around Benoist's absence until she returned to work in January 2021. ^{[40] [32]} Filming concluded on August 6, 2021. ^[38]

Marketing

In early August 2020, The CW released several posters of the Arrowverse superheroes wearing face masks, including Supergirl, with all posters having the caption "Real Heroes Wear Masks". This marketing tactic was used to "raise public awareness on the efficacy of facial coverings preventing the spread of COVID-19". ^[43]
