Midway through season three, Amy Jo Johnson requested that Kimberly be written off the show because she wanted to pursue other opportunities in acting. The character was accommodated with a 10-episode story arc focused on Kimberly, leading up to her departure. Kimberly and Aisha adopt a stray white cat, "P.C.," who is the secret form of Rita's new spy Katherine Hillard. Katherine also spies the Rangers in her human form; she ultimately develops feelings for Tommy and jealous of Kimberly's relationship with him, steals Kimberly's Power Coin; with the Coin in evil hands, Kimberly's very life force is in danger. Lord Zedd kidnaps Kimberly and uses her as ransom for the other Rangers, but they rescue her. Zordon disconnects Kimberly's connection to the Morphing Grid, forcing her to receive power from the other Rangers, much like Tommy had when he was losing his Green Ranger powers; Tommy consoled Kimberly through this time, as she had done previously for him.
