Our lord and savior!

Nikki is constantly depicted as an irreverent and snarky teenage girl. She is one of the original five members of the group, and takes the longest amount of time to warm up to Caitlin.

Nikki works at the Khaki Barn, a retail establishment which she absolutely loathes because of its commitment to conformity. She works there because it was one of the few stores that was both hiring and willing to take her on as an employee.

In addition to being snarky and sarcastic, Nikki isn't much of a romantic. In part, this is attributable to bad experiences in the past.

Despite her sarcastic and often aloof manner, Nikki has been shown to care for her friends deeply.

Clothing:
Nikki is always seen wearing multiple earrings, a necklace, a white top with a lime-colored circular shape on the middle of it, gray cargo pants, and light purple shoes. She also wears purple underwear as revealed in the episode "Wrestlemania". In the episode Nikki tries to look good for Stone, and she walks too close to an escalator causing it to rip her dress off leaving her standing in her underwear.
