Trakeena (Jennifer Burns)

In Power Rangers Lightspeed Rescue, it was revealed that she had survived and managed to return to her

human form, though was now horribly disfigured. She then made her way to Earth, planning to obtain her revenge on the Rangers by destroying their homeworld. She acquired the allegiance of the Demon Triskull and his army of ghouls, collecting energy to return to her insectoid form. To do that, she captured humans to drain their lifeforce. Leo teamed up with the Lightspeed Rescue Power Rangers in an attempt to stop her. However, Olympius, tainted the energy with a poison dagger, causing Trakeena to mutate into a gigantic monster. Despite the help of the Galactabeasts, the Galaxy and Lightspeed Rangers were unable to stop her until the Omega Megazord became infused with The Lights of Orion. Trakeena was then permanently destroyed and was never mentioned or seen in Power Rangers never again.
