Kathrine Hillard or Kat as she is called, first appeared back when the series was in the Ninja stage. Then, she was another servant of Rita. Rita had placed an evil spell on Kat much like the one placed on Tommy. Only she turned into a pretty white kitty cat to spy on the rangers. Later when she turned good, Kim gave Kat her pink power coin when she was leaving for the Pan Global Awards.
After Kim left, Kat went on to become the pink Zeo ranger, and the pink Turbo Ranger. She meets Kim again in the Turbo movie on the island of Muranthias. It's a good thing no hard feelings were between the two since Kat later snags Kim's boyfriend Tommy.
Kat Hillard is played by Catherine June Sutherland. Cat was born in Sydney, Australia on October 24, 1974. She was chosen to be the pink ranger after Saban conducted a world wide pink ranger search. (And how come I never heard of it until I conducted a research on Cat?) She beat out hundreds of other girls to become the newest pink ranger! Currently, she's in England studying dance.
Catherine has also been in "Mighty Morphin Power Rangers", "Power Rangers Zeo", "Turbo: A Power Rangers Movie", "Power Rangers Turbo", and "The Cell." She's also made an appearance on "Sweet Valley High."
