It is our job to take risks. We run into the line of fire. We face enemies that no one on this planet has the courage to.
—Alex to J’onn J’onzz


Alexandra “Alex” Danvers (born 1989) is a top agent of the D.E.O., the daughter of Jeremiah Danvers and Eliza Danvers, the adoptive sister of Kara Danvers and the girlfriend of Maggie Sawyer.

Alex is a courageous and independent person, 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 her good traits, sometimes Alex can be impulsive and prone make difficult decisions crossing the line between right and wrong; 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 in those occasions it was to save first J’onn J’onzz’s and then her father’s life. However she has great sense of justice, since when J’onn took the blame for Astra’s death, as he did want not Alex to lose her relationship with her adopted sister, knowing it was wrong, she eventually confessed to Kara role in Astra’s death despite her fear to lose her.

After much soul searching and exploration, Alex finds the courage to come out as a lesbian to herself, then to her new girlfriend Maggie Sawyer, then Kara and finally her mother Eliza. Alex’s interactions with Maggie show a more flustered, awkward and almost goofy side of her personality, similar to that of Kara.
