The evil Shadow Pink and Yellow Rangers
The Shadow Pink Ranger (Catherine Sutherland) and the Shadow Yellow Ranger (Nakia Burrise) were villainesses from "Shadow Rangers," the fourth episode of Power Rangers Turbo (airdate May 1, 1997).
The Shadow Rangers were evil doppelgangers of the Turbo Rangers created by the sinister Shadow Chromite, one of Divatox's monsters. The Chromite first appeared and confronted Adam Park, Katherine Hillard, and Tanya Sloan, after which he used his blaster to steal the three Rangers' powers when they started to morph. Afterwards, the Shadow Pink, Yellow, and Green Rangers emerged, cackling at their counterparts before defeating the powerless Turbo Rangers in combat.
The evil Shadow Pink and Yellow Rangers appeared with the Chromite and Shadow Green Ranger later on, this time going after Tommy Oliver and Justin Stewart. The latter of the two remaining Turbo Rangers attempted to morph, only for him to suffer the same fate, resulting in a Shadow Blue Ranger to join the evil clones. Justin was captured along with the others, with Shadow Pink left to guard them in the lit Chromite Cave. All the while, Shadow Yellow led Green and Blue in a fight against Tommy, who remained unmorphed to ensure that he wouldn't lose his powers.
Tommy defeated the three evil Rangers after learning that they were all made of light, and that darkness would destroy them. During the battle, Tommy sent all three of the Shadow Rangers into dark spots, with Yellow being the last of the three destroyed. After morphing, Tommy went to the Chromite Cave to rescue the others, only to battle Shadow Pink while doing so. Tommy used his blaster to destroy both of the lights in the cave, therefore destroying Shadow Pink.
