Astronema (played by Melody Perkins) is known throughout the universe as the Princess of Evil, Dark Princess of Space, and the Princess of Darkness, and is the main antagonist of Power Rangers in Space. She is also known for being one of two primary female villains in the Power Rangers series to enter hand-to-hand combat with the Rangers themselves. She carried a staff called a "Wrath Staff" that shot lightning, and a boomerang. Anytime Astronema is out of her Dark Fortress, she wears what she calls her "Battle Gear", which consists of two shoulder plates, a chest plate, and a back plate. This "Battle Gear" helps protect her when she is in hand-to-hand combat.
Once known as Karone, sister of Andros (the Red Space Ranger), she lived on the planet KO-35, a human space colony. She is kidnapped by Darkonda when she and Andros are playing in the park with a toy sphere and practicing telekinesis. She is transported to another planet, where she meets Ecliptor and Dark Specter, the Grand Monarch of Evil.
When Andros discovers Astronema's true identity, he did everything in his power to reform her. He very nearly succeeds. She came over to the Power Rangers' side, and Andros even made her an honorary Power Ranger. However, she is captured once again by Dark Specter and his forces after trying to save Earth from an asteroid sent by him. Ecliptor cybernetically brainwashes her, using advanced computer implants to suppress her emotions, and she is forced to be Astronema once again.
In the finale of Power Rangers in Space (Countdown to Destruction), she becomes the Queen of Evil after Dark Specter's destruction, much to Divatox's dismay. After she becomes the Queen of Evil, Zordon reaches out to her, telling her that because she is now the leader, she doesn't have to do Dark Specter's bidding anymore. His plea almost breaks through the power of the cybernetic brainwashing implants almost causing her to revert back into Karone, it does not work. Then, Astronema begins to attack Earth. Andros sneaks into the Dark Fortress and tries to convince his sister to stop and come back to him as Zordon did. A battle ensues, and when she delivers a powerful energy blast to finish Andros, he protects himself with his Spiral Saber deflecting it back to her, seemingly killing her. After Andros destroyed the energy tube of Zordon at his command, it released a wave of purifying energy that eradicated all evil, but left Astronema's body unchanged. Andros cried, and two tears ran off his nose and landed on her cheek. This removed Astronema's cybernetic programming. Restored, she returns to Earth with Andros and the other Rangers.
She was also Zhane's love interest for a time, but after Zhane had to stand her up to defeat a monster, she seemingly lost all interest in him, but was seen holding onto her photograph of him at the end of the episode.
In Power Rangers Lost Galaxy, Karone returned, as she welded the power of Kendrix's Quasar saber after Kendrix died and became the second Pink Galaxy Ranger.
