Kate

Kate (Japanese: ケイト Keito) is a character in the Game Boy Color version of Mario Tennis. She also made an appearance in Mario Power Tennis as a coach.

She wears a tank top, mini-skirt, bracelet, headband, and tennis shoes all colored pink, similar to Princess Peach's sports attire. In Mario Tennis, her hair and eyes are also pink. In Mario Power Tennis, she looks similar to what she looked like in Mario Tennis, though a little different; even though her tank top, mini-skirt, shoes, bracelet, and headband are still all pink, she has blond hair and blue eyes instead of pink hair and eyes. She and Harry have a friendly rivalry of sorts. At one point in the game, she gives Harry a push with her rear end, using him to knock down everyone behind her.
