Alexandra "Alex" Danvers is the deuteragonist of Supergirl. She is the daughter of Eliza Danvers and Jeremiah Danvers, and the adoptive sister of Kara Danvers aka Supergirl. Alex is an agent for the DEO and joins her sister in defending the Earth from regular and cosmic threats on the Superfriends.
Inspired by Supergirl, Alex became a hero and becme a vigilante after donning on a new suit empowered by Martian technology given to her by J'onn J'onzz and was eventually code-named Sentinel, which was previously used by an old friend of J'onn's named N'or Cott.
Alex is a courageous and independent individual who faces danger head on. She is caring, confident and headstrong with the same passion for bio-engineering like her parents. Alex had dedicated her life to protecting her sister, Kara and rarely found time for herself since teenhood.
Despite Alex's good traits, she can sometimes be impulsive and prone to make difficult decisions crossing the line between right and wrong (some might even classify her as morally grey), such as when she stabbed Astra in the back or when she assaulted a Cadmus facility on her own by placing mines in the structure to blackmail Lillian Luthor, even if on those occasions it was to save first J'onn J'onzz's and then her father, Jeremiah Danvers's life.
But Alex has a great sense of justice. When J'onn took the blame for Astra's death, as he did not want Alex to lose her relationship with her adopted sister, knowing it was wrong, she eventually confessed to Kara her role in Astra's death despite her fear of losing her.
After much soul searching and exploration, Alex finds the courage to come out as a lesbian to herself, then to her ex-girlfriend, Maggie Sawyer, then Kara, her mother, Eliza, her friends and her father, Jeremiah. Alex's interactions with Maggie show a more flustered, awkward, and almost goofy side of her personality, similar to that of Kara.
Above all, Alex is a strong woman. She fights for what she believes in and has a difficult time giving up. When she was kidnapped; by her childhood friend, Rick Malverne, she never stopped trying to escape and was able to use her D.E.O. training to help her survive. She has been referenced as being a "bad-ass" by several other individuals.
After losing Maggie, Alex became devastated, unable to cope and started drinking heavily. She is also fond of leather jackets.
Alex loves her sister, Kara, and asks J'onn to erase her memories of Kara's identity as Supergirl.
Alex later retrieves her memories when Supergirl saves her and fights Red Daughter.

Winn Schott[]
Prior to Kara coming out as Supergirl, Winn and Alex had little to no interaction until Alex came to Kara's apartment and discovered both Winn and James knew Kara's secret.
In episode 4, Alex asked Winn to hack into the DEO database in order to find out about her father, Jeremiah, but did not let out the details. Even though he initially refused, Kara told him that this information concerned about their father. Obligated to help due to his own strained relationship with his father, Winn discovered Alex's father and another agent had disappeared and then a month later, Jeremiah's partner, Hank Henshaw had returned. Since then, Alex has trusted Winn and has considered him a good friend, especially when they became colleagues in Season 2 and 3. When Alex came out as a lesbian, he was shocked yet comfortable with Alex's sexuality and her stable relationship with Maggie Smith.
In the third season, she even trusted Winn to watch over Ruby.
In Season 5, Winn and the Legion returned to help Kara, Alex and the Superfriends. After the defeat of Lex and Nyxly, Winn attended Alex and Kelly's wedding, where he performed a song with Kara.
