Psycho Pink

Psycho Pink was based on the brain wave patterns of Cassie Chan (as the PInk Space Ranger) and was more than well aware of Cassie's tactics and weapons.

She almost killed Cassie but was interrupted by Astronema  and, after being destroyed the first time, was digitized and sent to an unknown planet. When the Psycho Rangers returned in Power Rangers: Lost Galaxy  and were destroyed again, Pink was the only Psycho Ranger to survive, and then launched a new attack to claim the Pink Ranger powers. She managed to destroy the Pink Space Ranger's morpher with the Savage Sword, and while Psycho Pink fought the Space and Galaxy Rangers in their Megazords, the Pink Galaxy Ranger managed to destroy the Savage Sword and save the Pink Space Ranger at the cost of her own life. She turned into her plant like monster form again and was finally defeated by combined efforts of both the Astro Megazord and Galaxy Megazord.
 * Ironically Psycho Pink was the first Psycho Ranger to be destroyed during In Space but the last to be destroyed during Lost Galaxy.
 * She is the only Psycho Ranger to kill a ranger.
