Nicki Kapowski

"A person may cause evil to others not only by his actions but by his inaction, and in either case he is justly accountable to them for the injury."

- Nicki

Nicki Kapowski is Kelly's tomboyish little sister who developed a crush on Zack. She came off as an outgoing person and liked baseball.

Season 2
Nicki had a crush on Zack, and became convinced that Zack felt the same way after he mixed up her phone call with Kelly's (while running the "Teen Line"). Although she was only thirteen and in the seventh grade, she nonetheless showed up at Bayside High to visit Zack, sporting a more feminine look and demanding a kiss.

After trying various ploys to turn her off, Zack finally had to tell her the truth that he wasn't interested in her.
