Justice League Action Shorts S01E13 - True Colors

During Superman's fight with Metallo, Martin Stein advises Firestorm to use his powers to turn Metallo's Kryptonite power source into lead only to accidentally turn it into Red Kryptonite which induces Superman's anger, Gold Kryptonite that gives Superman amnesia, Black Kryptonite which splits Superman's personalities, and Pink Kryptonite that turns Superman into a woman as a result of not remembering how to turn Kryptonite into lead. Luckily, Ronnie wrote it all down.
