After the villain Ruin performed some experiments, two new Parasites debuted, one purple, the other green. The two new Parasites were teenagers named Alex and Alexandra, who wanted to seek vengeance on the people who made their lives difficult; they were soon subdued by Superman after a battle. After attempting to escape from a meta-human prison, the male parasite, Alex, was killed by an OMAC. His sister Alexandra, the female parasite, escaped and joined the Secret Society of Supervillains under Lex Luthor.
She later is one of the villains sent after the Get Out of Hell Free card from the Secret Six.
