The main cast of characters includes:

1. Frenni Fazclaire – A brown, chocolate-scented bear with blue eyes and long brown hair kept in a single, high ponytail, dressed in black thigh-high socks and a black thong, as well as fingerless, elbow-length black gloves, a slightly elegant, short-sleeved black-and-white crop blouse, and a matching top hat. She is the head vocalist and the leader of nightclub animatronics as she loves to dance, sing, and essentially acts as the group's mastermind.
2. Bonfie the Rabbit – A purple, blueberry-scented rabbit with pink eyes and short purple hair styled in a right-angled bob cut, dressed in dark red thigh-high socks, fingerless, elbow-length dark red gloves, and a dark red mini dress secured at the waist with a wide black belt. She is the lead guitarist and a gamer girl, as though seems highly skilled with technology, she excels even more when playing her guitar or arcade games, in which she is unbeatable.
3. Chiku the Chicken – A light-yellow, lemon-scented chicken with pink eyes and short light-yellow hair styled in a high side bun, dressed in orange thigh-high socks and a black thong, as well as a sleeveless white crop top with a pink inscription “LET'S RAVE!” She is the backing vocalist and basically a stereotypical blonde girl, whose talents only get overshadowed by her dumbfoundedness as while she's simply a genius in the kitchen, she's also not one of the brightest minds and eats just as much with gluttonous passion.
4. Fexa the Pirate Fox – A red-orange, strawberry-scented fox with yellow eyes and short but very fluffy unstyled red-orange hair, dressed in white thigh-high socks, ripped brown jean shorts, as well as elbow-length white gloves, and a sleeveless black leather cropped jacket. She is technically another vocalist, though she rarely performs with the rest of the gang, and instead has her own, separate pirate-themed attractions, acting as the group's muscle, but also antisocial, grumpy, and hostile jerk.
5. Golden Frenni (also known as Goldie) – A dark-yellow, honey-scented bear with empty eye sockets and long and very messy unstyled dark-yellow hair, dressed identically to the original Frenni. She is the most enigmatic member of the gang, not only lacking any official function but also rarely interacting with anyone as most consider her damaged beyond repair, crazy, and too dangerous for public use as she is currently marked “out of order.”
6. Marie Onette – A black-and-white marionette with no scent, full black eyes and short white hair styled to rise upward, dressed entirely in a full black bodysuit with white buttons and adorned with dozens of white stripes. She is the merchant of Frenni's Nightclub and manages the Prize Corner, acting as the de facto gift shop seller rather than an actual performer as she's openly not as action-starved as the rest and mostly ends on flirting and teasing.
