Kara Nivoire

Kara Nivoire is a student at Sunnydale Heights High School. Zack Jackson first meets Kara during gym class on his first day, when he encounters her as a shark and promises to take her to the big Halloween Dance in exchange for not being eaten. According to Kara, she was the star swimmer for Sunnydale Heights until "last fall", when she was cursed by the old English Lit teacher to remain a shark until she found true love.

Kara surprises Zack by revealing that he is her true love, a fact which Zack disputes. The two experience a brief, tempestuous relationship, but break up during the big Halloween Dance.
