Supergirl uses Gold Kryptonite to remove the powers of Black Flame permanently.

Synopsis:
A female super villain with all the powers of Supergirl begins attacking Earth. Supergirl responds to the emergency and learns the villain is called the Black Flame. The villainous claims she is from the future and a descendant of Supergirl herself. Supergirl researches the claim and cannot find evidence to disprove it.

Supergirl then decides to remove her own powers using Gold Kryptonite to prevent her descendant from receiving them. After exposure, Black Flame reveals that she is really a Kandorian named Zora, enlarged by a Red Kryptonite cloud. After the Red K wears off, she shrinks to normal size and Supergirl uses tiny grains of Gold K to remove Zora’s powers. She herself never used real Gold K, so Supergirl is able to retain her own powers. Zora is then sent back to Kandor for incarceration.
