Katherine Hillard

Katherine Hillard (played by Catherine Sutherland) is the Pink Power Ranger of the third generation in the series Mighty Morphin Power Rangers.

Kat came to Angel Grove from Surrey Hill, Australia as a junior in high school. Rita Repulsa had made her an evil spy and gave her dark powers as well as the ability to turn into a cat. She had to be found by Kimberly Hart and Aisha Campbell, the Pink and Yellow Rangers, as a cat and was adopted by them. She spies on the Rangers to gain information on their lives.

Kat stole Kim's power coin which weakened Kim. Using the coin, she was able to break into the Falconzord and capture it, rendering the other Ninjazords useless.

When Kimberly fell at the Youth Center due to her weakened state, Kat felt responsible, as she felt guilty. This ultimately helped break the spell that Rita had over her.

Kat had returned Kim's Power Coin and became her replacement as Kim left for the Pan Global Games. She controls the Crane Ninjazord and became the Pink Ninja. She copilots the White Shogunzord with Thomas Oliver, the White Ranger. There was a point where she wanted to date Tommy, but it never got to that until they were no longer Power Rangers. The bond that did develop was first shown when she was able to break the control Prince Gasket had over Tommy after a long brainwashing.

After the Ninja powers were destroyed, Kat had to travel to Australia to find the pink Zeo Subcrystal.

In Power Rangers: Zeo, Kat became the Pink Zeo Ranger (Zeo Ranger I Pink), piloting the Zeo Zord I and Super Zeo Zord I.

Kat later became the Pink Turbo Ranger and controls the Wind Chaser Turbozord during Power Rangers: Turbo.

Kat graduated Angel Grove High as valedictorian and continued to help freshmen at the school. She gave her powers up to Cassie Chan to pursue other things in life. She is currently attending the Royal Dance Academy in London.

At some future point in an alternate timeline, she weds Thomas Oliver and they have a child together. Their descendants are also Power Rangers, but they may not be aware of this. Whether these events will still occur after various time-travelling incidents (in which neither Tommy nor Kat were involved) is unknown, but the events of Power Rangers: Dino Thunder do not suggest that they are likely.
