Astronema

Astronema is known throughout the universe as the Princess of Evil, Dark Princess of Space, and the Princess of Darkness.

Once known as Karone, sister of Andros, the Red Space Ranger, she lived on the planet KO-35, a human space colony. While playing with her brother, in the park, they were developing telekinesis as they played with a toy sphere. When the sphere floated away, Andros went after it, and Karone was captured by the vile Darkonda. Screaming for help, she was transported to another planet, and met Ecliptor and Dark Specter, the Grand Monarch of Evil.

She was left in the care of Ecliptor who became a fatherly figure to her and trained her to be an evil warrior. The memories of being Karone faded away. Ecliptor had told her lies of the Power Rangers destroying her parents and her brother. After years of training and competing against other evil warriors, Astronema was later tutored in the dark arts of magic. She was awarded the Wrath Staff, which she uses to manipulate others and battle her opponents. With Dark Specter's help, she gained the space station, Dark Fortress, and an army of robotic soldiers called Quantrons. Astronema is known to change her hairstyle and color at will. She wore her locket that had the same pictures of her and Andros as children, however, she refused to acknowledge that she and Andros were siblings until later.

As Astronema roamed the universe, conquering and destroying all those who would not serve her or Dark Specter, she would destroy them or turn them into his slaves. She met a warrior that carried the Armor Keys, magical talismans that would grant him great armor. To prevent the warrior from using the keys, she turned him into a stone figure.

Astronema had found herself in love with the Silver Ranger, Zhane. However, due to one another's lies (which were truths), their relationship ended badly.

When she found out who she truly was, she had sided with her brother, Andros, and helped him find Zordon. She was later captured by Ecliptor, who was brainwashed, and was condemned to the same fate as he. Her emotions were removed and was inflicted with cybernetic implants that controlled her.

She was transformed back into Karone during Countdown to Destruction. She and her brother battled when a deflected energy bolt struck her. Only the love Andros felt for his sister was strong enough to bring her back.
