Character: Moxie is the leader of the group. She possesses an insatiable curiosity, boundless self-confidence, and a unique ability to make others feel truly themselves, yet she also yearns for something more. She's also a staunch optimist, ready to embrace any challenges she must overcome to reach the "big world."

Character: Tuesday is a ditzy, perfect doll and one of Lou's three main friends. She spends a lot of time trying to impress Lou, even though it's clear he's not interested in her.

Like Kitty and Lydia, Tuesday can be very cheeky, although she is also prone to forgetfulness and silliness.

Appearance: Tuesday has ivory skin, short, shoulder-length light blue hair, and light blue eyes. She wears a school uniform like the other Ideal dolls. In some scenes, she wears a black bodysuit, like a spy.

Character: Lydia is sassy, ​​yet the most caring of the spy girls. However, while Kitty is caustic and sarcastic, and Tuesday is frivolous, Lydia is more emotional and cries when she learns Kitty stole her earrings.

Appearance: Lydia has dark skin, purple hair pulled back into a low ponytail, and golden-brown eyes. She wears a school uniform like the other Ideal dolls. In some scenes, she appears in a black bodysuit, like a spy.

Character: Mandy is an insecure doll who hangs out with the Spies to fit in. However, Mandy finds it difficult to be as cruel to the dolls with imperfections as the others, as she herself is not perfect. She has poor eyesight, which she hides from everyone, especially Lou.

Appearance: Mandy is an African-American doll with purple hair pulled back into a high bun and brown eyes (gold, hazel, or orange, depending on the lighting). She wears a black vest with two gold buttons over a white collared shirt with a blue tie, purple plaid shorts, white knee-high socks, and black high heels.

Character: Kitty is the leader of the Spy Girls, an elite squad of three dolls who work for Lou.

Like the other Spy Girls, Kitty is a sassy and sarcastic puppet. However, of the three, she is the least sensitive and doesn't seem to care about upsetting her friends. Kitty has also been shown to enjoy impersonating Lou, suggesting she's less in love with him than Lydia and Tuesday.

Appearance: Mikhail is a perfect doll with normal skin, unruly blue hair, and blue eyes. He's dressed like all the dolls in a school uniform, a short-sleeved shirt, a vest, a tie, and socks.

Character: Mikhail Kukla is an engineer by profession. He's confident, calm, sometimes smug and arrogant, but not always. He's also kind.

Appearance: Lou is a puppet in the form of a young man, aged between 16 and 25. He has a typically "Aryan" appearance: he has fair skin, blond hair, and blue eyes, but despite his hair color, his eyebrows are brown, almost black. He also has a short hairstyle combed to the right side. While all the other students wear school uniforms, he wears an elegant black two-piece suit with two gold cufflinks and a purple checkered tie, along with black business shoes.

Character: In his first appearance, the antagonist is presented as a blunt and rude character, reminiscent of a popular school bully. He mercilessly calls every doll ugly, but by the end of the concert, he politely explains to the Uglydolls that they are not meant for the Big World, suggesting he's trying to be sophisticated. However, during his backstory, it's revealed that when he first arrived at the institute, Lou was more beautiful than any doll, both physically and emotionally, a trait that is further revealed through his friendship with Ox: while the other students simply turned away from the imperfect doll, Lou showed greater compassion, becoming Ox's best friend and trying to help him become a better person so he could see the Big World. Even Lou's face then reflected his love for all living things. Over the course of Ox's construction of Uglyville and the time the main characters settled there, Lou became increasingly inhumane. The thought that all his students would replace each other, nullifying the idea of ​​a long-lasting friendship between them and the prototype, Lou stopped seeing the point in any moral compass and drowned out any pity for those who would eventually leave him, and due to the fact that Lou would never see the world of people just because he was forced to mess around with other dolls, he began to hate them altogether. Lou was created as a prototype for the Model 12 dolls, his job is to help the dolls become like him, which speaks of his physical and moral superiority over others.

Appearance: Nolan has pale skin, even slightly more so than the other dolls. He has heterochromia iridis (Iritis), a green eye on the left and a purple eye on the right. His hair is dark brown with a green streak in his bangs that falls over his eyes. He has uneven freckles scattered across his cheeks. Like all the dolls, Nolan wears a school uniform, but his sleeves are long, his vest is sloppily worn, slipping off one shoulder, and his tie is awkwardly tied. He also doesn't wear socks like the others.

Character: He's a rather shy doll who doesn't live up to Lou's standards. He's quite quiet due to his lack of friends. Nolan is the most unique doll, besides Lou, at the Institute for Perfection. His awkward appearance and imperfections make him a unique doll. "Not being perfect makes him perfect." He also hates dogs because he's afraid of them.
