Created by Lex Luthor in the Time Trapper’s pocket universe, Matrix is an artificial shapeshifting telekinetic life-form modeled on the late Lana Lang. After the death of the universe’s only superhero, Superboy, Lex Luthor accidentally freed three Kryptonians from the Phantom Zone— General Zod, Quex-Ul, and Zaora. Matrix fails to successfully defeat them on her own, and is sent back in time and across universes to enlist the help of Superman. Even with his help, they fail to stop the Kryptonians before they kill off almost everyone in the universe, and only Matrix and Superman survive. Lex Luthor reveals to Superman with his dying words two important things: a way to stop the Kryptonians, and that Matrix is not Lana Lang herself, but instead an artificial being.

Superman takes Matrix home with him to the Kents, who take her in as their own and help her recover from the shock of losing her home and discovering that she’s not truly Lana Lang, nor even human. Superman soon leaves her and the Kents to go into space and recover himself— and his absence combined with her identity issues result in Matrix having a psychotic episode and beginning to believe she is Clark Kent. This is not helped when he returns to Earth with the Eradicator, which psychically links him with Matrix and worsens the delusion. Soon brought back to her senses, Matrix mimics Superman and leaves on her own exile.

She decides to identify as Supergirl again after an encounter with Draaga, the Cellkeeper, and Brainiac gets her caught up in a fight between War World and Earth.

After her return to Earth, she ends up in the hands of Lex Luthor II/Jr. Initially mistaking him for her late creator, she falls in love with him at first sight. She would stay with him and listen to his every word, through the Death of Superman to a bit after his return. A meeting with Elizabeth Perske, Lex Luthor’s ex wife, would cause her to become suspicious of Lex and his associates. After finding out he’d been lying to her and cloning her, she confronts him and leaves him.

She then spends some time with Elizabeth Perske in Charlotte, North Carolina, away from Lex and from Superman’s shadow in Metropolis. Unfortunately, her time there is cut short when she’s kidnapped by Raven, after which she joins the New Titans for a little while before having to leave again to help save Superman from being sentenced to death by an alien tribunal.

Shortly after her return to Earth, she saves the life of Linda Danvers, a human girl from Leesburg, Virginia. She fuses with her, and the two of them share a body. After that, her time is split between Linda’s human life and her Supergirl life.

After many adventures with Linda, she eventually is separated from her. When she asks Linda to fuse with her again, Linda says no, and she fuses with Twilight instead.

Mae is eventually retconned from continuity with Infinite Crisis in 2005, but the footnotes in the recent New History of the DC Universe (2025) #3, she’s mentioned in passing, implying she’s canon again now.
