When Kimber was growing up, she was upset because she was the youngest child and felt she was sometimes left out. It wasn't until Lela arrived at Starlight House when that feeling went away, as Lela was younger. When Kimber was nine, her mother, Jacqui, died in a plane crash, leaving her and her foster sisters in the care of her father. After he died, she, Aja, Shana and Jerrica found instruments, a computer called Synergy, a car called the Rockin' Roadster, and clothes that their father left for them. She and her foster sisters then formed The Holograms. She's the keyboard player, sings backup vocals and is the main songwriter of the band.
When Kimber left the band briefly, she went into a nightclub to ease her mind and there she met Stormer, who had also departed from her own band, The Misfits, that very same day. The owner insisted they performed together; they set aside their differences and performed the song "I'm Okay" with the Limp Lizards playing the rest of the instruments and providing backup vocals. Both girls became fast and best friends, and even recorded an album called Back to Back, which was a success and went double platinum. When Stormer went back to the Misfits and Kimber returned to the Holograms, they maintained their strong friendship.
Kimber is the youngest of the Holograms. She tends to be a bit immature and let her emotions control her actions. She has run away and rebelled several times during the series and sometimes still acts very much like a child, even though she is only three years younger than Jerrica. She's a hopeless romantic and always has guys falling for her. Kimber has had at least five boyfriends throughout the series, including Sean, Jeff and Steve. She wasn't very committed in her relationships and tended to have unrealistic expectations and far-out ideals.
Kimber has blue eyes and red hair (which in some episodes may look pink). She wears many different outfits throughout the series, but her most common is a white jacket with a red ruffled shirt, blue slacks and pink heels.
She and Jerrica share a very strong bond and are very close, although Jerrica sometimes tends to look down on her and act more like a mother. Sometimes she wishes Jem was her sister instead of Jerrica.
Kimber didn't like Aja when she was adopted by Emmett, but she grew on her over time. She thinks Aja can be cold at times, as revealed in the episode Scandal, although they really do care for each other.
It seems they care for each other, but she thinks Shana can be really annoying when she shows insecurity about her talents. She was very upset when Shana departed from the band in the episode The Talent Search.
They haven't interacted much with each other throughout the series, but they do tend to pop off at each other in the episodes Kimber's Rebellion, Glitter and Gold and Hollywood Jem. They do express their friendship for each other and she wouldn't have imagined not inviting him to her wedding. They have worked together in some occasions and are friendly to each other.
Kimber used to hate Stormer, as she was one of the Misfits, but when Kimber and Stormer quit their respective groups, they formed a friendship over their passion for music and formed their own group in The Bands Break Up. When they returned to their own respective bands, they remained friends.
Kimber and Eric interact many times throughout the series. Eric occasionally shows interest in Kimber, possibly in a romantic way, since he always compliments her and tries to pit her against Jem (Starbright). There are other moments when Eric offers her to ally with him, usually with the hidden intent to regain control of Starlight Music. In general, Kimber despises Eric.
