Supercorp

"Supergirl may have saved me but you, Kara Danvers, are my hero"

- Lena

SuperCorp is the femslash ship between Kara and Lena from the Supergirl fandom.

Season 2
Kara and Lena meet when Kara covers the rebranded L Corp for CatCo and they get along well. In time, Kara comes to support Lena when others question her company due to the bleak Luthor reputation and they become friends. Their relationship quickly intensifies and Lena becomes Kara's best friend. They have an easy chemistry and bond as two strong women in their working and personal lives. Lena's relationship with her family is antagonistic at best and she is continually disappointed by who she discovers is actually her adoptive mother. When Lena's ex-boyfriend comes to National City and is murdered, a devastated Lena is comforted by Kara, who promises she will never leave the lonely Lena — that their bond is everlasting. Kara is beside herself when Mon-El's mother abducts Lena and does everything in her power to rescue her best friend, while Lena's smarts and technical prowess helps Kara board the ship where they're held.

Season 3
Following Mon-El's departure, Lena tries to reach her best friend who is keeping everyone at a distance. Under threat to be bought by a sexist moron, CatCo is rescued by Lena who decides to invest in the company to prevent Edge's propaganda and to further give something valuable to the citizens of National City and beyond. It finds Lena being Kara's boss, something they both have to adapt to which leads to conflict when Kara rebuffs Lena's concern while also neglecting her work. They later make up and Kara apologises, talking to her best friend about what's really going on with her.

Lena continually supports Kara through her heartbreak and the best friends become closer than ever, all the while figuring out their new dynamic of working together. Lena worries that as a Luthor she is destined for evil deeds or — at the very least — to always be haunted by her family's nefarious history in both her work and personal life. Thankfully, Lena doesn't shut off but decides to confide in Kara her doubts which Kara helps thwart. Following Lena's ordeal with being accused by Edge of poisoning kids, Lena, Kara, Sam and Alex become something of a family unit, always standing by each other.

Lena's romance with James doesn't wreak havoc with her and Kara's friendship, despite Kara's past with James. Lena and Kara's relationship does suffer when Kara learns that Lena had some Kryptonite that she never told anyone about, although she claims what they used was the last. Kara suspects Lena might have more kryptonite and asks James to break into LutherCorp to find out. Nevertheless, they work together to help save Sam from Reign in the dark forest plane, without hindrance of mistrust between them. After James tells Lena what Supergirl asked of him, Lena becomes increasingly distrustful of Supergirl and tells her so, when Supergirl tries to establish a truce between them. Lena tells Supergirl that they were never friends and, with Lena's history, trust broken is a faux-pas. Lena also tells off Supergirl for her double standards regarding trust. The strain on Lena and Supergirl's relationship takes its toll on Kara, although she remains determined to hide her alter ego from Lena to protect her.

Lena seems to have surmised that they are one and the same, but doesn't let on in her interactions with Kara, leaving it uncertain whether she knows Kara's secret identity. Lena remains friends with Kara and even throws her a goodbye party when Kara decides to live on Argo City. With Kara away, Lena and Alex also work together to help Sam, in which Alex seems to trust Lena despite knowing everything in the Supegirl/Lena conflict. Despite all this, their conflict seems to calm a bit as Kara returns to Earth to help stop Reign once and for all.

Season 4
6 months pass after Sam was saved, and for a while Lena goes to the LCorp Metropolis branch to help settle Sam as the head of that department. Lena returns and Kara is overjoyed to see her again at CatCo. Lena gives Kara information for an article on the family's former boydguard, Mercy Graves, and also gathers intel on Graves by visiting her mother, Lillian Luthor, in prison, where Supergirl also shows up, surprised to find Lena. Kara and Lena have lunch together at LCorp when Graves attacks the building. Kara, Lena and Eve Teschmacher are together as the building's put on lockdown, but are chased by Graves and attempt to escape through the security mechanisms. Kara hilariously tries to separate herself from them to become Supergirl, while Lena insists Kara will be the safest with her.

Eventually Kara manages to leave the room in time to save Lena from Mercy Graves. Mercy and Otis are briefly incarcerated at the DEO, but let out by a DEO defector. The Graves siblings and Agent Liberty release Kryptonite into the air and Kara is infected. J'onn manages to catch her just before she plummets to her death, but Kara's condition is critical. Alex summons Lena to the DEO and Lena arrives exuding a mix of determination to help and anguish at the state Supergirl is in. Lena encapsulates Kara in a suit which cleanses the air of Kryptonite to allow Kara to survive until they figure out a way to remove the Kryptonite from the atmosphere. Lena and Brainy figure out a way to do so, and Kara remains in the suit until the air is fully cleansed, with Lena on coms to tell her that she is finally free again.

To have some fun, Kara gathers her friends for a brunch, which Lena also attends and where they toast to having a good time. Lena is also over at Kara's for Thanksgiving dinner and meets Kara's mother, Eliza, for the first time. They all discuss the rise of hate in the world and Kara feels that regular people are powerful in their own right, where Lena suggests giving 'good' humans alien-level powers to minimise fear. Without telling anyone but Eve, Lena performs her first test on a human subject, while Kara is nearly killed by the Agent Liberty militia.
