BoJack Horseman

BoJack Horseman (voiced by Will Arnett) is a self-loathing 52-year-old alcoholic horse whose acting career peaked when he starred in a successful show called Horsin' Around, a 90s family sitcom. Though he began as a young bright-eyed actor, he has since grown bitter, deeply depressed, and jaded towards Hollywood and who he has become post-fame. Bojack has been shown to be caring and insightful, but his insecurities, loneliness, and desperate need for approval often result in self-destructive actions that devastate those around him.

Princess Carolyn

Princess Carolyn (voiced by Amy Sedaris) is a pink Persian cat who is BoJack's agent and former on-and-off girlfriend. Earnest and unflagging, Princess Carolyn was a top agent at Vigor agency through her dogged pursuit of new talent and large network of odd personal connections. Though she struggles to find a balance between work, her troubled personal life, and taking care of Bojack and her friends, she enjoys her fast-paced hectic lifestyle. She seceded from Vigor to start a new agency with her then-boyfriend and coworker Rutabaga Rabitowitz. After recognizing his duplicity and confronting her fear of being alone, she ultimately decides to leave him and run the new company named VIM by herself. After several setbacks, Princess Carolyn closes VIM in Season 3, only to reopen it as a management agency.

Diane Nguyen

Diane Nguyen (voiced by Alison Brie) is a human ghostwriter, misunderstood intellectual, and a Vietnamese-American third-wave feminist from Boston who lives with her rich and famous boyfriend (and later husband), former sitcom star Mr. Peanutbutter. While writing BoJack's memoir, he and Diane initially develop a strong friendship that becomes increasingly awkward and strained after BoJack develops romantic feelings for her. Diane travels to the war-torn Republic of Cordovia to make a difference, but discovers that this life is not for her. Ashamed of returning to her husband, she develops a severe bout of depression, during which she drinks heavily and sleeps disheveled on BoJack's patio furniture. She is able to reconcile her feelings with Mr. Peanutbutter and gets a job at VIM ghostwriting tweets for celebrities. She is subsequently fired from VIM, and is hired to write for a feminist blog.

Mr. Peanutbutter

Mr. Peanutbutter (voiced by Paul F. Tompkins) is an energetic and cheerful yellow Labrador Retriever who is BoJack's former sitcom rival and Diane's boyfriend (and later husband). Mr. Peanutbutter was the star of Mr. Peanutbutter's House, which, according to BoJack, "borrowed the premise" from Horsin' Around. He had a stint at filming a celebrity reality show called Peanutbutter and Jelly. Despite their rivalry, Mr. Peanutbutter cares a great deal about BoJack's opinion and admires him for his work on Horsin' Around. He has an especially good relationship with Todd, and his positive attitude and financial resources combined with Todd's outlandish schemes and plans often result in the two starting questionable business ventures, such as a Halloween store that is exclusively open in January. In the episode "Let's Find Out", Mr. Peanutbutter starts hosting his own televised game show after his film company enters bankruptcy due to his and Todd's extensive expenditures on useless products. In "Hank After Dark", it is revealed that Mr. Peanutbutter was formerly married to a woman named Katrina who was emotionally abusive. His second wife was famous actress Jessica Biel, who is portrayed as being obsessed with her celebrity status and people recognizing her. He grew up in the Labrador Peninsula, which is depicted as being populated entirely by Labrador Retrievers. "Mr." is his actual first name. He often shouts to an offscreen presence only known as "Erica".

Todd Chavez

Todd Chavez (voiced by Aaron Paul) is an unemployed but well-meaning and friendly 24-year-old human slacker who ended up at BoJack's house for a party five years before the beginning of the series and never left. Although BoJack constantly voices disdain for him, he secretly cares about Todd, continuing to financially support him and sabotage his attempts to gain independence. Todd has been shown to possess a plethora of skills including an understanding of Japanese; entrepreneurial know-how, having allied with Mr. Peanutbutter for various business ideas; and writing and composing his own rock opera- Newtopia Rising, Book I: The Search for a New Utopia. His rock opera was eventually sabotaged by BoJack, who took advantage of his former addiction to video games. Todd puts the pieces together of what BoJack did string map style and begins to question his friendship with Bojack. Todd also has an uncanny knack for getting himself in absurd and extremely dangerous situations when his friends aren't around, such as getting into gun fights on several occasions, ending up in prison, and in one case switching places Prince and the Pauper-style with a Cordovian dictator. Todd's friendship with Mr. Peanutbutter landed him various jobs creating seemingly useless products. He sees the best in BoJack, despite his multitude of problems. He's usually happy, even when being insulted by BoJack. Catch Phrases include shouting Hooray! He is also almost never seen without wearing his signature yellow beanie. It is revealed in the season 3 finale "That Went Well" that he is asexual.

Recurring characters

Pinky Penguin

Pinky Penguin (voiced by Patton Oswalt) is an Emperor penguin who works at a publishing house and depends on BoJack's book to save his job and company. In "Yesterdayland", Pinky started working at MBN. At the end of "Later", it is revealed he was able to see his kids again. After Wanda moves to Detroit, he becomes the head of MBN.

Sarah Lynn

Sarah Lynn (voiced by Kristen Schaal) is a human actress who played the Horse's precocious adoptive youngest daughter Sabrina on Horsin' Around, and who looked up to BoJack off-screen as a father figure. After the show went off the air, she became a successful pop singer in the early 2000s before drug addiction and alcoholism ended her career. Flashbacks indicate that Sarah Lynn's self-destructive behavior is in part the result of being forced into an acting career by her mother, and BoJack (whom she idolized) having neglected her as a child. Around the end of "Later", she was seen visiting Andrew Garfield (with whom she was mentioned as having an on-again, off-again relationship) at the hospital. It is heavily implied that she was sexually abused as a child by her mother's boyfriend and later stepfather. Although Bojack attempts to get her sober earlier in Season 1, he later goes on a bender with her and Todd in an attempt to rewrite his memoir after firing Diane.

In Season 3, she becomes sober, but only because she hears that taking drugs after being sober for a long time is the best experience. When BoJack hits rock bottom, he invites Sarah Lynn to go on an epic bender. Through a series of blackouts, they have a series of misadventures attempting to make amends to BoJack's ex-friends, and even stalking Penny at Oberlin College. Along the way, Sarah Lynn wins the Academy Award for Best Original Song in absentia. She then admits to Bojack that she doesn't like anything about herself and, at the Griffith Observatory planetarium, dies lying on BoJack's shoulder after a drug overdose. In "That Went Well," it is revealed that Bojack tried to get her to guest star on "The Bojack Horseman Show"

Herb Kazzaz

Herb Kazzaz (voiced by Stanley Tucci) is BoJack's human former comedy partner, who created and wrote Horsin' Around where he also provided the voice of Mr. Libertore who runs the law firm where the Horse works as an attorney. When BoJack and Herb first meet as comedians, BoJack angrily tells him to "get cancer" which is what eventually happens. The pair had a falling out at the apex of the show's success when Herb was blackballed by the network for being gay and BoJack did not stand up for Herb for fear of losing his own job. At the beginning of the series, they have not spoken for nearly 18 years. BoJack attempts to reconnect with him after learning Herb has been diagnosed with terminal rectal cancer and is being watched over by Tina. Though Herb reveals he lived a full life in spite of losing Horsin' Around, he has not forgiven BoJack for not having been a supportive friend. Despite his cancer going into remission, he instantly passes away due to an allergic reaction to the peanuts on a peanut truck in a car crash when his brakes gave out during a ride home from the hospital. It was also revealed that Herb's office was under the room where Savion Glover kept a studio. Following his death, Henry Winkler and Tina stole the manuscript of his poorly written novel to keep it from being published and tainting his legacy. In "Out to Sea", Herb's ashes are donated to the Jerb Kazzaz Memorial Orphanage (misspelled due to BoJack's email and the hedgehog owner's stubbornness to pay for its replacement).

Tina

Tina is a brown bear who is the nurse of Herb Kazzaz. In "Still Broken", Tina was in collaboration with Henry Winkler to keep Herb's terrible manuscript for a novel from being posthumously published and harming his legacy. Unlike the other anthropomorphic characters on the show, Tina only speaks in growls.

Charlotte Moore

Charlotte Moore (voiced by Olivia Wilde) is a deer who was Herb Kazzaz's old girlfriend with whom BoJack was once in love. During a drug and alcohol induced stupor in "Downer Ending", BoJack imagines an alternate life where instead of becoming a television star he moves to Maine with Charlotte. In this fantasy, the couple get married, have a daughter named Harper, and lead a quiet rustic lifestyle.

In "Still Broken", Charlotte attended Herb Kazzaz's funeral. In a discussion with BoJack, she mentioned that she visited Herb and read the part in BoJack's book on how he and Herb fought over a telescope. She tells him she only lived in Maine for a month and later moved to Tesuque, New Mexico. In "Escape from LA", BoJack drives to Charlotte's house to find she is married to Kyle and has two teenage children named Trip and Penny. She also owns a store called "Your Deer Friend". During his time in New Mexico, BoJack bonds with the 17-year-old Penny by becoming her "date" for prom. When Charlotte catches BoJack and her daughter in a compromising position in his yacht, she orders him to get off her property in half an hour before she calls the police. Furthermore, Charlotte also states to BoJack that if he contacts her or her family again, she will kill him.

Beatrice Horseman

Beatrice Horseman (voiced by Wendie Malick) is a horse who is BoJack's neglectful, verbally abusive mother. Heiress to a sugar cube company, she primarily appears in flashbacks to BoJack's childhood.

Butterscotch Horseman

Butterscotch Horseman (voiced by Will Arnett) is a horse who is BoJack's physically and verbally abusive father. He appears in flashbacks to BoJack's childhood. Butterscotch, who hailed from a working-class background, was an alcoholic failed novelist. He resented his wife's financial independence and took out his insecurities on BoJack. In flashbacks, Butterscotch is often seen yelling nonsensical conservative hyperbole such as claiming that the Panama Canal is for "Democrats". A flashback in "Brand New Couch" revealed that Butterscotch left Beatrice. It has not yet been revealed if he is still alive.

Lenny Turteltaub

Lenny Turteltaub (voiced by J.K. Simmons) is a turtle and big-shot film producer. He worked with Ed Begley, Sr., Lionel Barrymore, Buster Keaton and Edwin S. Porter during their youth, suggesting that he is extremely old (a reference to the lifespan of actual turtles).

The Paparazzi Birds (voiced by Adam Conover and Dave Segal) are an unnamed blue jay and American robin duo who would try to get incriminating pictures of BoJack.

Sextina Aquafina

Sextina Aquafina (voiced by Aisha Tyler in season 1-2, Daniele Gaither in season 3) is a bottlenose dolphin pop-music sensation. In "Out to Sea", Diane meets with Sextina to discuss becoming her social-media ghostwriter. In the season three episode "Brrap Brrap Pew Pew", Diane accidentally tweeted out that Sextina was having an abortion while she was being distracted, which caused a media storm. While Sextina was initially angered with the tweet and tried to fire Diane, she later embraced the image because of support from other celebrities. She later released a music video militantly supporting abortion, had her "abortion" on live TV, and soon after became pregnant. It is implied that she is sent to a farm where celebrities go to disappear.

According to creator Raphael Bob-Waksberg, she is based on a girl who was in his and Lisa Hanawalt's English class as a senior in high school.^[2]

Kelsey Jannings

Kelsey Jannings (voiced by Maria Bamford) is a human who was hired to direct the Secretariat movie. A divorced, lesbian, independent filmmaker, she sees the Secretariat project as her last chance to break into the big time and make enough money to get her daughter Irving into an Ivy League school (as opposed to Vassar). Cynical and initially dismissive of BoJack's talents, she and BoJack grow closer over the course of filming. She has a special fondness for Todd because she likes his face. She is later fired by Lenny Turteltaub in "The Shot" for filming a scene that involved Secretariat's encounter with Richard Nixon.

In season three, BoJack finds Kelsey at POFF (Pacific Ocean Film Festival) and attempts to reconcile with her through a note, but she cannot understand it because the ink starts to wash away. Later in the season, the two discuss doing a serious film together to legitimize BoJack as an actor. Unfortunately, this is part of a plan by Vanessa Gekko to sabotage Princess Carolyn. The resulting fallout seemingly ends Bojack's unique professional and artistic connection with Kelsey.

A Ryan Seacrest Type

Tom Jumbo-Grumbo

Tom Jumbo-Grumbo (voiced by Keith Olbermann) is a blue whale who is a newsman and pundit on MSNBSea (a parody of MSNBC). Tom often reports on BoJack's misdeeds and other happenings in Hollywoo.

Charley Witherspoon (voiced by Raphael Bob-Waksberg) is a tree frog who is the son of Mr. Witherspoon. He works at the Vigor agency where his hand keeps sticking to things. Charley was briefly Princess Carolyn's assistant, but was later made an agent.

Vincent Adultman

Vincent Adultman (voiced by Alison Brie^[3]) is Princess Carolyn's boyfriend. Everyone except BoJack appears oblivious to the fact that he appears to be three children standing atop each other underneath a trench coat. Though he speaks in a child's voice and has awkward syntax, he also occasionally exhibits strangely keen insight, prompting others to ignore BoJack's observations. In Season 2, Princess Carolyn meets Kevin, who appears to be the top child of Vincent's trio. He tells Princess Carolyn that Kevin is Vincent's son, which she believes, but leads to them breaking up.

Dr. Allen Hu

Dr. Allen Hu (voiced by Ken Jeong) is a human physician who sells drugs to Sarah Lynn. An unseen character throughout most of the first season, he is the subject of a recurring joke based on the phonetic similarity of his name to "who" with BoJack and others believing that Sarah's drug connection is a man who simply calls himself "Doctor Who" rather than an actual physician. He made his first onscreen appearance in "Downer Ending."

Sebastian St. Clair

Sebastian St. Clair (voiced by Keegan-Michael Key) - A snow leopard billionaire bachelor who wants Diane to accompany him to a third world country, Cordovia. Though Diane initially looks up to him because she wants to change the world in a positive way, she quickly becomes disillusioned when it becomes clear he is more concerned with making a legacy for himself than with actually helping people.

Jogging Baboon

The Jogging Baboon (voiced by Jason Beghe) is an unnamed white baboon that is often seen jogging by BoJack Horseman's house. In "Out to Sea", the Jogging Baboon comes across BoJack jogging. He tells BoJack that jogging may be hard at first, but it will get easier if he does it every day.

Wanda Pierce (voiced by Lisa Kudrow) is an owl who is a network-television executive at MBN. She woke up from a 30-year coma that she somehow ended up in and began a relationship with BoJack. Because she had missed the last 30 years of pop culture, she is initially unfamiliar with BoJack's history and fame, and must learn what transpired in the world while she was in a coma. She and BoJack break-up in "Yes And" where she claims that she can not have a relationship with someone as bitter as BoJack. It is revealed in the season three premiere "Start Spreading the News" that Wanda moved to Detroit after receiving a position at a TV company there.

After revealing his reluctance to divorce yet wishing to continue the affair, Princess Carolyn abandons him.

Mr. Peanutbutter idolizes him and treasures having met him at the awards after-party. He is the host of a TV dance competition Hey, I Think You Can Dance. Hippopopalous is known in the TV industry as Uncle Hankie.

Roxy

Roxy (voiced by Fielding Edlow) is Diane's old friend. She was initially introduced as her and Mr. Peanutbutter's wedding officiant in "Horse Majure".
