This is a list of characters that are featured in the book series and PBS Kids GO! show Arthur which began airing in 1996

The children



 * Arthur Read is the title character of the series. He is a third grade student at Lakewood Elementary in Elwood City. He has two younger sisters, Dora Winifred (D.W.) and Baby Kate. He possesses a sincere partiality towards reading, watching television, playing sports, playing piano and spending time with his friends. He is an aardvark[1]. He wears a yellow cotton sweater and a pair a of blue jeans.


 * Alan "The Brain" Powers is one of Arthur's friends and classmates. He is a mild-mannered only child, who excels in academics and athletics. He spends his free time working at his parents' ice cream parlor, while also managing a career as a great soccer player. Brain is an original character from the Arthur books. Brain had a secret that he had flunked Kindergarten, in "Brain's Shocking Secret." He is represented as a bear. He wears olive green pants and a gray sweatshirt with a white modern collar.


 * Binky Barnes is a one of Arthur's friends and classmates. He was originally written as a bully, who secretly harbors sensitive and caring feelings. He enjoys studying the fine arts, including playing the clarinet and performing ballet. He was the leader of a "bully clique", known as the Tough Customers, which in later seasons takes on more noble endeavors. He is now portrayed as one of Arthur's best friends but still acts rashly at times. In the episode "Binky Goes Nuts," it is discovered that he is allergic to peanuts. Recently, his family adopted a baby sister, named Mei-Lin, from China. Binky is an original character from the books. He wears an orange shirt and casual blue pants.


 * Mary Alice "Muffy" Crosswire is Francine's best friend, though they are opposites in many ways. She is the wealthiest girl in school, and is generally potrayed as a stereotypical rich and spoiled girl, thinking money can even buy her way out of an electrical blackout, shown in the episode "The Blizzard." She tends to be extremely self-centered, and like Francine, her behavior occasionally leads her into trouble with her friends. She also tries to impress her friends with her dad's wealth, who is the wealthiest businessman in Elwood City, and because of this she is often labeled as a show-off by her friends. Muffy has an older brother named Chip. Her signature hairstyle is ponytails, usually braided, and had buck teeth as she did in the books on several but not all episodes of season 1. She is shown as a monkey in a white blouse with a purple jumper and two matching bows to tighten her braids.


 * Buster Baxter is Arthur's best friend. A jolly and upbeat figure, Buster enjoys watching television, reading works of science fiction, conjuring conspiracy theories, playing video games, playing the tuba, and above all, eating. Despite his excessive eating habits, he is surprisingly lean. He has asthma. He is also very superstitious at times, and is obsessed with extraterrestrial life. Buster lives with his mother, Bitzi, and occasionally travels with his father, Bo. Buster also had his own spin-off series, entitled Postcards from Buster.[2] He is shown as a rabbit with a greenish blue sweater with a pink collar and blue jeans.


 * Francine Alice Frensky is a tomboy who loves sports, drumming and singing. She is the best player on her team in just about every sport they play, rivaled only by the Brain. She is also good at the drums and singing, but has unsuccessfully tried to do them simultaneously. Her blunt, outspoken demeanor can sometimes have a negative effect on her relationships with friends and relatives. She is of Polish-Jewish descent. She can occasionally be bossy to her friends. Francine is best friends with Muffy Crosswire. She and Arthur occasionally fight, but make up in the end. She is shown as a monkey with a red sweater with blue jeans and sports a barrette on each side of her hair.


 * Fern Walters is one of Arthur's classmates. She is one of the series' quieter characters, who enjoys reading poetry and mystery novels. Fern's mother, Doria, is constantly trying to get Fern to become more extroverted, and even Fern herself sometimes worries she is "too quiet". She is known for her realistic storytelling, especially when telling horror stories based on Mary Shelley's Frankenstein. She has much talent for solving crimes, and being an amateur sleuth. One of her favorite authors is Persimmony Glitchet, a reference to famous author Lemony Snicket. Most of the time Fern is shown in a purple long sleeved blouse with yellow buttons and yellow pants, always sporting a red ribbon in her hair.


 * George Lundgren is one of Arthur's classmates, and is a moose, or something in the family Cervidae. Like Fern, he is very quiet. He has dyslexia and is well-known in his class as a ventriloquist, performing with his dummy, Wally. He is often isolated from his classmates because of his frequent nosebleeds, which grosses out everyone. He is of Scandinavian descent. His last name was formerly "Nordgren" until Season 11 and onwards which has now been changed to "Lundgren". He and Francine were dance partners in a dance competition. George is shown with an orange shirt and blue jeans.He is said to have a crush on Jenna.


 * Jenna Morgan is a minor character in Arthur's grade. She plays badminton, helps coach soccer, received an Athlete of the Year award from Michelle Kwan, and is allergic to milk (making her lactose intolerant). Jenna also suffers from bedwetting. In Jenna's Bedtime Blues, George has a crush on her, as she said her secret was a crush on George to not admit her bedwetting to her friends. Jenna is shown as a cat in a pink dress with yellow buttons and hot pink interior.


 * Prunella Deegan is a grade above Arthur and his friends, and as a result is somewhat snobbish and condescending towards the younger kids. She brags about winning competitions from last grade and tends to bring it up to Arthur and his friends. She is interested in yoga, fortune telling, and paranormal phenomena. She wears a blue dress with a white collar and a purple bow tie on her head.


 * Sue Ellen Armstrong is a recent transfer to Arthur's school. Her father is a diplomat, and so her family has lived in various spots around the world. She is interested in world culture, and has a black-belt in the martial arts. She also practices taekwondo, and is not afraid to challenge someone much bigger than herself. She can whistle, and though she is an only child, keeps in touch with her brother-like friend on the other side of the world. In "Sue Ellen's Lost Diary", it is hinted that she has a crush on Arthur. She is shown as a cat with a white and blue low-cut vest and navy blue skirt.


 * Adil Akyuz (a-KOOZ) is Arthur's 8-year-old Turkish pen pal who was introduced in "Dear Adil". He and Arthur have a lot in common. Adil has an annoying younger sister, Aisheh, who loves the Turkish version of Mary Moo Cow (Arthur became very upset when Adil and Aisheh sent D.W. a Turkish Mary Moo Cow CD) and a best friend named Andhur (AHN-door) who has a personality like Buster.


 * Alberto Molina, is the teenage older brother of Vicita Molina and of Arthur's newer neighbors. He became a character during season six, following the departure of Mr. Sipple. Alberto and his family hail from Ecuador. He practices kendo in his spare time, and enjoys reading "El Conejo Bionico", the Spanish version of Bionic Bunny.


 * Catherine Frensky is Francine's older sister, 14 years old. She is a monkey and reads teen magazines and frequently hogs the phone. She is envied by Francine, since Francine believes that her parents favor her older sister and Catherine is better than Francine at many activities, particularly acrobatics and horseback riding.


 * Chip Crosswire is Muffy's older brother who is a college student at Tallahassee Tech, a fictional school. He was first subtly revealed on "Arthur's Perfect Christmas" (there were separate Christmas stocking for Chip and Muffy side by side in their fireplace), but was later directly mentioned in the episode "Phony Fern". His first appearance was in "Matchmaker, Match Breaker" when he comes home from college, where Muffy and Francine try to hook him up with Francine's sister Catherine.

Dora Winifred "D.W." Read is Arthur's little sister and is a middle child. She attends preschool and enjoys watching children's television shows much to Arthur's annoyance. She is also known for her many short-lived obsessions and tantrums if these obsessions are not fulfilled. Many of the series' plots revolve around tensions between D.W. and her brother, and she is naturally better than Arthur in some activities such as fishing, which causes her brother to envy her. At times, she can be self-centered, annoying, says cruel things to Arthur and other people, and always tries to get Arthur in trouble, and make him look bad. But other times, she does show appreciation for Arthur being her older brother. She goes by the nickname "D.W." due to an evident dislike for her full name.

Emily is one of D.W.'s classmates and friends. She first met D.W. in a gymnastics class, and later became a regular character in the series. She outshines D.W. in many activities, and D.W. often tries to outperform her, but with mixed results. She possibly has a French heritage because she is closely associated with French culture, and even has a French nanny. Emily was at first seen as a rabbit with tall ears, short blonde hair, and a red floral dress. In the sixth season, her design changed to much longer hair, and a blue dress.

Kaitlyn "Baby Kate" Read is Arthur and D.W.'s baby sister. She's able to communicate with Pal and other animals but people who are older than her dismiss it as "baby talk" gibberish, and Kate and the animals interpret grownups' talk likewise. She is an aardvark and enjoys playing in her sandpit and shows remarkable intelligence for her age and limited knowledge, despite not being able to communicate with people older than herself.

Marina Dattilo is Prunella's best friend. She is a rabbit, blind, and loves Henry Skreever, the show's parody of Harry Potter. She and Prunella met when Prunella unwillingly received a Braille edition of the latest Henry Skreever and let Marina borrow it, and since then they have become inseparable. Marina is notably good at yoga and joined Prunella and her mother, Wanda, in their early-morning yoga routine.

Mei-Lin Barnes is Binky's baby sister who was adopted from China. In her debut (at the Chinese restaurant), she was talking to Baby Kate. She and her brother are very close to each other. Mei-Lin first appeared in the season 11 finale, "Big Brother Binky".

James MacDonald: The younger rabbit brother of Molly MacDonald, his fourth grade sister. He is in Ms. Morgan.'s class, and is often shy. He is sometimes annoyed by D.W.. In one episode D.W. would bug him to kiss her.

Molly MacDonald is close friends with Binky. She is a rabbit and another antagonist and a senior member of the Tough Customers. She is known to be good at giving advice, but dislikes the fact that everybody comes to her for it. Molly has short maroon hair that completely covers her eyes, giving her a rebellious appearance. She has a little brother named James who is in D.W.'s preschool class. She became friends with D.W. and Arthur eventually, but both sides have agreed to keep this secret from their friends.

Monique "Mo": Arthur's cousin, whom Arthur remembers when she had been awful to him in the past reunions and tries to avoid her, until it is revealed that Mo isn't as bad as Arthur thought. She, like Arthur, plays the piano, and claims that Arthur is her favorite relative. Monique only appears in Arthur's Cousin Catastrophe.

Nadine is D.W.'s imaginary friend. She portrays D.W.'s conscience, and usually appears when D.W. feels guilty, scared, or angry. Both girls are aware that Nadine is imaginary, since only D.W. sees her. One episode shows D.W. with her when she's much older, while another shows that D.W. does not need Nadine as much as she used to. She has long platinum blonde hair styled exoticly in three pigtails and small buck teeth. She can create imaginary items and appear/disappear with magic.

Rattles Ciccone is another member of the Tough Customers, and is one of the antagonists. Rattles has been a Tough Customer member since the first season of the program. He wears a backwards baseball hat, black leather jacket, white T-shirt, green jeans and high tops.

Rubella Deegan is Prunella's older teen sister. She is very spiritual and obsessed with psychic and paranormal phenomena. She is typically depicted as a mystical, and she often talks in a very dramatic tone. She often chides in on Prunella.

Tommy and Timmy Tibble are twins who routinely exasperate Arthur, D.W., and most everyone with their mischievous antics. In the early episodes in the first season, the characters at D.W.'s preschool who were mischievous were named Billy and Bobby. Billy and Bobby were later replaced by the Tibbles. Tommy wears a red scarf and Timmy wears a blue scarf.

Vicita Molina is Arthur's neighbor. She is the younger sister of Alberto Molina who moved in after Mr. Sipple moved out and was introduced in sixth season. She's three and seven-eighths, in her own proud words, and often plays with D.W. and the Tibbles.

Otis is a student in Arthur's class. He is almost always portrayed as a background character. In Dancing Fools he is Muffy's dancing partner.

His physical appearance has changed several times.

Coach Grimslid : The Lakewood Elementary School Gym Coach who was mainly seen in earlier episodes.

Miss Blank: A past substitute teacher of Mr Ratburn's class. Strangely, she was the classe's favorite substitute teacher because she never showed up and the class had to be taught by Miss Sweetwater, who let them do coloring and gave them snacks.

Mrs. Bofini: A past substitute teacher of Mr Ratburn's class. The class disliked her because she had the habit of sucking her teeth and batting her eyelids.

Herbert Haney: Mr. Haney is the lovable yet absentminded principal of Arthur's school. He, like George, suffers from dyslexia. He also seems to have bad luck: something goes wrong almost everywhere he goes. A running gag in the show is a random item falling on his head, usually unintentionally caused by another character, such as Francine throwing a baseball way off course in "Arthur Makes the Team" and Loretta Duong flipping the burgers too high in "Arthur's Cousin Catastrophe". Both ended up accidentally falling on Herbert's head. They also often call him "sir" instead of Mr. Haney, as if he were a stranger despite the fact that he is their principal.

He also enjoys magic tricks and spent a summer working at Jack's Joke Shop. He is also knowledgeable about Japanese lutes, such as the Biwa, but is noticeably incompetent with computers.

Mrs. Pariso: Francine's next door neighbor, who is very good at horseback riding and also won prizes at Wimbledon.
