Kimberly is one of the original five Power Rangers chosen by Zordon when Rita Repulsa attacked Earth following her release from containment. She, along with her close friends Jason Lee Scott, Zack Taylor, Billy Cranston and Trini Kwan, was one of the five teens chosen by Zordon to receive a great power, drawn from the spirits of the prehistoric animals. Kimberly receives the Pterodactyl Power Coin and the Pterodactyl Dinozord, thus becoming the Pink Power Ranger. Kimberly starts the series as a stereotypical valley girl, but with a heightened awareness for her friends. Throughout the series, she is the member of the team most likely to fire off a sarcastic or witty retort. However, as the series progresses, she becomes a deeper and kind-hearted person, due to experiences such as switching bodies with the nerdy Billy Cranston and being turned into a punk after Baboo administers a potion to one of Kimberly's drinks. She also displays a cunning, clever and intuitive side, also inherited from her time in switching bodies with Billy.
