Kimberly Ann Hart is the Pink Mighty Morphin Ranger, the Pink Zeo Ranger and the first Pink Aero Ranger. Kimberly spent 13 years as a Ranger before passing her powers to Cassie Chan. In Mighty Morphin Power Rangers: Revisited, Kimberly never left to train for the Pan Global Games (Gunthar instead chose Katherine Hillard on Kim's request), and remained on the Ranger team to receive her new Zeo powers from Prince Alpha in the next saga, Power Rangers Zeo: Revisited and received her Aero powers from him in Power Rangers: Aero. The reason why she declined is because she felt that her Ranger duties were more important than starting a gymnast career, and she has some very special beings in her life that she would miss gravely if she left (referring to Alpha and Tommy).
