Main characters
The Belcher family runs "Bob's Burgers", a hamburger restaurant. Despite routinely cycling through seasons and holidays, the characters remain perpetually the same age.
Bob Belcher (H. Jon Benjamin) is the owner of Bob's Burgers. He is Linda's husband and Tina, Gene, and Louise's father. He is 46 years old and has black hair with male pattern baldness and a thick mustache. Bob's youth mostly consisted of working in his father's diner after his mother died, before he left to start Bob's Burgers against his father's wishes. Bob typically serves as the straight man to the antics of his family and friends, though he is also quite stubborn and is prone to being very petty and competitive, especially against people he dislikes. Despite his pessimistic personality, Bob loves and cares for his family and his restaurant, and tries to do what is best for them. He enjoys cooking, restaurant appliances, foreign films, and Thanksgiving. In the restaurant, Bob is the cook.
Linda Belcher (John Roberts) is Bob's wife and Tina, Gene, and Louise's mother. She is 44 years old, always wears her signature red glasses, and speaks with a thick, heavily-pronounced New Jersey/New York accent. Linda is quirky, happy-go-lucky, and enthusiastic in whatever she does, to the point of sometimes bursting into made-up songs about everyday things, serving as a foil to Bob. She is very supportive of her family and her children's schemes, and provides advice or assistance where she can, though she can be strict as well, showing less leniency when Louise does not listen to her. Linda frequently winds up in comedic situations trying to prove herself to be a loving wife and mother. In the restaurant, Linda is the cashier and clerk.
Tina Belcher (Dan Mintz) is the eldest of the Belcher children, at 13 years old. She has myopia and relies on her distinctive large glasses for sight. Tina is socially awkward, insecure, easily influenced by peer pressure, and tends to freeze up and produce a long groaning sound when faced with decisions or conflict, but she is also capable of showing courage and taking responsibility when she has to. She is often assigned caretaker for Gene and Louise when they are home alone, though they frequently take advantage of her naivety to bring her along in their plans. Tina is going through puberty and has many crushes on many boys, primarily Jimmy Jr., one of her classmates and the son of Bob's rival Jimmy Pesto. She has some sort of fetish for butts and zombies, reflected in the fan fiction and "erotic friend-fiction" she tends to write. Tina obsesses over what others think of her and struggles to fit in with her friend group at school, consisting of Jimmy Jr., Zeke, Tammy, and Jocelyn. She is interested in horses, the fictional tv show The Equestranauts, and the popular boy band Boyz4Now. In the restaurant, Tina is a server, but is not good with customers.
Gene Belcher (Eugene Mirman) is the middle child and only son of the Belcher family, at 11 years old. Gene is confident, laid-back, enthusiastic, and loud, like Linda, though he also resembles Bob when he was young. In many cases Gene serves as comic relief, often by making double entendres or cultural references. He is the least mature out of his siblings, being distracted often (called "Gene-ing out" within the family), exhibiting poor hygiene, and playing make believe often, though he can also show resolve and do what is right. He regularly expresses oedipal tendencies. He is open to conversation and has many friends in school, including Alex, Courtney, Lenny, and Peter. Gene is an aspiring musician and often plays with his sampling keyboard and megaphone while dabbling in writing songs and musicals on various topics. Besides music, he also enjoys fashion in which he occasionally cross-dresses without judgment from his family or neighbors. In the restaurant, Gene advertises out front in a burger costume, but often also works as a server.
Louise Belcher (Kristen Schaal) is the youngest of the Belcher children, at 9 years old. She always wears a distinctive pink hat with long bunny ears that she has had since preschool. She is a mischievous schemer with an egotistical and cynical personality who is experienced in manipulating others to get her way, but in many cases her conscience intervenes and she becomes a reluctant antihero who ultimately does what is right, though she tries to hide her honest feelings. Amongst the siblings, she takes leadership and authority, and often challenges traditional gender roles with her assertive, intense nature. She strongly cares for her family (particularly Bob), and plans to take over the family business when she gets older, but is also willing to take advantage of her family when it suits her. Her friends at school include Regular-Sized Rudy, Darryl, Andy and Ollie, and (mostly one-sidedly) Millie. Louise enjoys Burobu, a Pokémon-like collectible card game, as well as Boyz4Now member Boo Boo, though she strongly represses her interest in the latter. In the restaurant, Louise is often a server but mostly helps her siblings with cleaning, refills, and other busywork.
Teddy (Larry Murphy) is a bumbling but kind handyman. He is a regular at Bob's Burgers, to the point of being described as "living" in the restaurant, and views himself as having such a dedication to Bob and the restaurant that he tries to hide his patronage at other restaurants such as Jimmy Pesto's Pizzeria. Teddy regards Bob as his best friend, a sentiment Bob begrudgingly reciprocates, and is honorarily considered an uncle to Tina, Gene, and Louise. He admires the Belcher family dynamic, particularly Bob and Linda's marriage, and frequently joins the Belchers in their schemes. He is often shown to be lonely and unlucky in love, but eventually falls in love with Helen, before later starting a relationship with Kathleen. Teddy is prone to extreme emotions, somewhat socially awkward (especially around women), and frequently goes off on very long stories and tangents about mundane topics.
