Katherine first met the Rangers on the opposing side: as a spy for Rita Repulsa. Yet her true, gentle nature couldn't remain contained by the spell, and she managed to break free on her own. Her selfless nature shone through when she risked her life for the Pink Coin, and that nature made her compatible with the power of the Pink Ranger. She served only a short while as the Pink Morphin' Ranger, but she forged the foundation of a lengthy and worthy career that continued through Turbo.
