Buster Baxter is a third grader at Lakewood Elementary School. He is in Mr. Ratburn's 3rd Grade class with his best friend Arthur Read, and the rest of his friends. He resides in Elwood City in a condominium with his divorced mother, Bitzi Baxter.
When Buster was a baby, he was wearing a purple shirt, disposable diapers (colored gray instead of white to avoid mixing in with his white complexion), and red and white sneakers. When he was around two years old, he wore a dark bluish-green sweater and light bluish-green shorts and sneakers. It was also revealed in "Arthur's Baby" when he was 2–3 years old he would cause his mother a lot of trouble by "stealing" foods (Basically eating them without having payed for them).

Family and home
Buster is the only child of Bitzi and Bo Baxter. His parents are divorced; he lives with his mother in a condominium in central Elwood City. His mother is a "worrywart" who often fears for Buster's well-being throughout his daily life, but in later seasons she has learned to relax more. They are extremely close and are like best friends. Buster has gone on many travels with his dad, such as in the spin-off series, Postcards from Buster. His father, besides in Postcards from Buster, has made appearances in a few episodes. He and Buster are also very close, and Buster thoroughly enjoys the few opportunities he has to see his dad.
In recent seasons, Bitzi started dating Harry Mills, a fellow photographer and journalist at the Elwood City Times. After getting over his initial theory Harry was an alien, Buster became best friends with Harry, having shared the same interests in sports, aliens, etc. Buster was disappointed to learn that his mom broke up with Harry much later on in the show, but the three of them remain the best of friends.
In Other Media
In the Living Books computer games such as Arthur's Teacher Trouble, Arthur's Birthday and Arthur's Computer Adventure, Buster's complexions ranged from white to cream-colored. In these three games, he was voiced by Robert Bell before the cartoon show replaced him with Daniel Brochu.
Buster is an anthropomorphic white rabbit who wears a cyan polo shirt with pink collar, jeans, orange boxer shorts with a Saturn design (white briefs in the books), and red and white sneakers. He only wore suspenders on his pants during Buster's Amish Mismatch. In the books, he wears different-colored shirts. He also has buck-teeth that are visible when he opens his mouth (in the early books, his buck teeth were especially visible with his mouth closed, but the TV series and later books had his buck teeth only visible with his mouth open). His sleepwear includes a purple button-up pajama top with dark pink dinosaur designs, dark pink pajama bottoms, and aardvark slippers. His swimwear includes blue swimming trunks with periwinkle dots. In "D.W. All Wet", his mom required him to wear a bathing cap to keep his ears covered, but in many later episodes, Buster no longer wears the bathing cap. On formal occasions Buster wears a navy-blue tuxedo jacket. He also sometimes wears a white shirt, red bow tie, matching trousers and brown shoes. When he first appeared in Arthur's Eyes in 1979, he had whiskers like a normal rabbit, but the whiskers were removed in Arthur's April Fool in 1983.
Buster is easygoing, fun-loving, and somewhat odd. He has a strong interest in space aliens, and claims to have seen flying saucers over Elwood City. His easygoing personality often takes its toll on his performance at school: he sometimes has trouble finishing reports, math assignments, and book reports. However, it is usually that the poor performance is due to lack of effort rather than low intelligence. As seen with some subjects he has an interest in, such as paleontology, he has given answers smart enough to impress Brain. Generally, Buster has a somewhat short attention span. He doesn't have the patience for reading books, unless it's a book he really likes (such as the Scare-Your-Pants-Off Club Series). He also has trouble keeping secrets.
Buster also has a strong love for food, and will eat virtually anything, and thus one of the show's running gags features him pigging out wherever he goes. Some of his eating habits are rather unhealthy, though, with him consuming food while following the "5-second rule" or ingesting foods that are beyond expiration. In one episode Buster even claims to have eaten a two year old cupcake and says that the icing was still soft. He also has a personal food collection in his room from his various travels or simply because he is fascinated with what he eats on a particular day. His mom often has the job of throwing this food out when it goes really bad. However, he is surprisingly lean. He used to eat a lot when he was young too.
Buster also is shown to have poor hygiene. He sometimes chooses not to wash his hands when he should. He occasionally is very dirty, and doesn't maintain his hair well. In fact, during an outbreak of lice in the school, Buster was the only one unaffected because his hair was simply too dirty to support the vermin. He eventually became a germaphobe, until his friends calmed him down, and after which, he became much more hygienic.
Although Buster is generally a nice person, he has been shown to resort to stealing if he sees something he wants, but can't have. However, after stealing an item, Buster will feel guilty about doing so and sometimes worry about being arrested for breaking the law. In the end, however, Buster returns the item. It has also been established that if Buster gets angry about something, he'll tend to hold a grudge, and it is usually the only thing he'll talk about until he can either forget the situation, deal with the situation, or speak to the person who caused the problem with him if this is the case. Most of the time he follows a strong moral code, like insisting that Arthur give James a refund for the defective toy he bought.
Whenever something happens with no known explanation, Buster will almost always become completely convinced that the cause was aliens. The suggestion is usually put down by his friends, yet Buster will continue to suggest aliens whenever something unexplainable happens. Occasionally when something unexplainable happens, another one of the gang will suggest aliens before Buster does. Buster then genuinely believes them until the person points out that the only reason they said it was because they knew Buster would've said it if they hadn't.
Buster can sometimes be influenced in a very big way; when Mr. Ratburn's class went on a field trip to an Amish farm Buster became fascinated by their way of life for a short time and even wanted to become Amish himself.
When it comes to tests, exams, or homework Buster is usually forgetful and just carries on with watching TV and hanging out with his friends before getting started on his work at the last minute.
If Buster is insulted or something he owns is insulted he will get quite angry about it and doesn't talk to the person much afterwards. However when he does, although he is still generally still mad at them, he will usually forgive them after an apology is given or an explanation is made.
