===Main===
* Beetlejuice (voiced by [[Stephen Ouimette]]) -– A [[ghost]] and the main and title character of the show, who enjoys eating bugs and is known throughout the Neitherworld as a prankster. He is the oldest son of Gnat and Bee Juice (who nag him to get a job and to keep clean, and who always address him as "Junior"), and he has a "disgustingly cheerful" younger brother, called Donny Juice (who, whether he realizes it or not, gets on his older brother's nerves). Beetlejuice was named after the star [[Betelgeuse]]. Beetlejuice is able to change shape, transform and conjure objects, teleport, and perform other feats of magic, although his powers can be reduced by various circumstances, such as when he feels fear, or when his head becomes separated from his body. At times, he must pause to think of exactly how to use his powers to escape a precarious situation unscathed. Due to what is later described in the series as his "juice" (his inborn source of magic), whenever Beetlejuice utters aloud a [[figure of speech]], he or his surroundings change to act on the pun. Almost all of his transformations maintain the black-and-white striped pattern he wears on his suit, although sometimes the stripes are colored depending on the transformation. Though many Neitherworld denizens have some magic, it is Beetlejuice's greatly superior power (no real cause for it is ever given) that affords him the title—albeit mostly self-asserted—of "The Ghost With The Most" (another line borrowed from the movie); in fact, on multiple occasions, Beetlejuice was able to effortlessly subdue a number of supernatural beings, and his dis-corporeal, self-sentient brain once claims that Beetlejuice's power is more than enough to conquer the whole Neitherworld. Because of that power, almost everyone in the Neitherworld is fair game for his pranks, though no more so than he himself, since he is not immune to careless use of his power. Sometimes Beetlejuice will mix up one of his transformations, due to [[homophone]]-based confusion (when Lydia told him to turn into a stake to fight off Count Me-In, he turned into a flank steak). At times, various of his body parts (including his feet and his entire torso) manifested minds of their own, independent of Beetlejuice's control, with his brain and even his entire [[skeletal system]] having to abandon him once. Beetlejuice's main pastime is pulling various pranks on the other denizens of the Neitherworld such as Jacques, Ginger, The Monster Across the Street, Poopsie, the Mayor and in the Living World it is Lydia's rival Claire Brewster and occasionally her parents.
Beetlejuice's pranks on many seem to cause them great embarrassment or damage, but his pranks on Lydia however, are only done to tease her, not to cause harm, which shows he cares for her. Lydia in fact seems to be the only person who has any control over Beetlejuice. He even said in one episode he would do anything for her, and she, in turn, reciprocates his feelings. Beetlejuice is also constantly coming up with get-rich-quick con schemes to get money, as he dreads having to get a job, and in later episodes (particularly in the second half of the fourth season), Beetlejuice's greediness becomes so intense that he sometimes overlooks his friends and family, and even when Lydia openly scolds him, Beetlejuice shows unbelievable reluctance or unwillingness to give up of his schemes. His favorite foods are insects of various types, especially beetles, and worms. Beetlejuice also loves causing mayhem in the Neitherworld and being filthy, and this last makes Beetlejuice have a pathological and psychotic hatred of baths. Despite this cynical and childish attitude, Beetlejuice proves to be a profound and insightful person, frequently reciting quotes of philosophical and humanitarian importance. The things he hates include cleanliness and anything "''cute''". He expresses his likes and dislikes via variations on a single [[catchphrase]], as in "''[[Nerd]] humor you know I love it!''" or "''rules you know I hate 'em!''" The only known thing Beetlejuice is afraid of is Sandworms, so much that he is unable to use his powers when he encounters them. However, on a few of occasions, Beetlejuice has managed to conquer his fear and use his magic to fight them. This is usually thanks to encouragement from Lydia, or if someone else is in danger. Lydia once stated to Judge Mental; ''"Beetlejuice couldn't use his powers to save himself, but he could do it for a baby."'' A number of times, Beetlejuice interacted with Lydia's parents in the "real world" of Peaceful Pines, always under the name of "Mr. Beetleman", and in a couple of instances, he performed a gender change on himself to become a teenage girl about Lydia's age at Lydia's school as "Mr. Beetleman's" younger female relative "Betty Juice", along with twice appearing as the male gender "Cousin BJ" claiming to be on Delia's side of the family.
* Lydia Deetz (voiced by [[Alyson Court]]) -– A Goth girl in her preteens at the start of the series, and early teens later in the series. Lydia main hobby is reading literary classics such as the collective works of writers such as [[Edgar Allan Poe]], [[Stephen King]] and other Gothic and horror writers. She is established as being a creative, bright, lively, sharp, yet [[Eccentricity (behavior)|eccentric]] young girl, but otherwise Lydia's unique outlook on life makes her stand out from most of the other school-girls, which leaves her feeling out of place and alone in the real world, finding it difficult to fit in well with most of her classmates—leading her to frequently visit and seek out reassurance with her closest friend, Beetlejuice, in the Neitherworld, where she is accepted and loved for who she is as a person. Her regular outfit at home is a long dark purple top, a pair of black leggings, a light purple and pink [[sash]] tied around her waist and black slipper-shoes. Her Neitherworld attire consists of a large spiderweb pattern red poncho, over a full-body black [[Unitard]]. Lydia is a talented [[Photography|photographer]], [[sewing|seamstress]], and artist with an affinity and love for all things gross, scary, weird, surreal and macabre, and who celebrates all that is (in the words of her film incarnation) 'strange and unusual'. Despite her love of all things 'strange and unusual', Lydia is also a [[Optimism|positive]], well-mannered, friendly and patient girl, and aside from also being emotionally mature for her age, Lydia can be accredited as being very responsible for a girl in her age group. Lydia is also shown to be a [[naturalist]], shown to feel very strongly about [[Environmentalism|environmental issues]], even to the extent of chaining herself to a tree, which Beetlejuice soon brought to life to save it from being cut down. Lydia has also shown that she is extremely gifted with anything mechanical and understands a lot about cars (she knew what to do to build Doomie, while "Bee-gor" Beetlejuice did not know very much, such as what a [[carburetor]] is). In the series, Lydia attends "''Miss Shannon's School for Girls''" and is in the seventh grade. As mentioned, Lydia is Beetlejuice's best friend; and in the events of the pilot episode, ''Critter Sitters'' it is revealed she and Beetlejuice have already known each other for a year, as they are celebrating their first anniversary of friendship. Beetlejuice frequently addresses her as "Lyds" or "Babes" rather than "''Lydia''" though he does use her full name from time to time, like when he is scared, amused, or worried about her; for example: in "Worm Welcome" when Beetlejuice found out that "Worm Your Way" deodorant causes baby Sandworms to go crazy, he was scared Lydia would be eaten by the baby Sandworm, this, in turn, makes himself shout her name. Lydia knows how to summon Beetlejuice to her presence or make her own way to his: by calling his name aloud three times. (Occasionally she is shown making use of a longer, more elaborate ritual using the aforementioned four-line chant to bring him out of the Neitherworld or send herself into it, but this seems not to be a necessity.) Unlike Beetlejuice himself, Lydia is almost universally loved by the Neitherworld denizens, and she once won a Neitherworld award for Cutest Mortal to Ever Visit the Neitherworld. Having found herself a kindred spirit in Beetlejuice, Lydia looks up to Beetlejuice in many ways, primarily admiring his outrageous sense of humor. In one episode, Beetlejuice lent Lydia his funny bone so she could be funny as part of a school show, but without his funny bone Beetlejuice became much more serious and normal; this change in him even disappoints Jacques and Ginger. When Beetlejuice gets his funny bone back however, he becomes his abnormal self again much to Lydia's delight as she hugs him. It is revealed in "It's A Wonderful Afterlife", that if she had never met Beetlejuice, Lydia would have become an unhappy, social recluse, and not have had the confidence to stand up to Claire Brewster's bullying; indicating that Beetlejuice's friendship and dedication to her is the source of Lydia's own self-confidence. Although most of Beetlejuice's antics are motivated by self-amusement rather than malice, he can become genuinely hostile if Lydia is threatened, and any who might conceivably threaten their relationship. These are the objects of Beetlejuice's profound jealousy and resentment. However, Lydia never shows any romantic interest in anyone else except Prince Vince, and that quickly turns into a straight-out friendship. In the episode "Out of My Mind", Lydia is teleported inside Beetlejuice's mind, and it is learned that he actually has a working shrine to her in his head. During this time, she gave a donation towards the maintenance of his shrine to her.
===Supporting===
* Poopsie (voiced by [[Len Carlson]]) – The Monster's beloved and talented pet dog, one of Beetlejuice's favorite prank victims, and because of this he strongly dislikes him, but he has the same affection towards Lydia as his owner. Poopsie's girlfriend is The Monstress Across the Street's dog Poopette. Poopsie is also one of Doomie's favorite targets when the roadster undergoes his Jekyll/Hyde transformation (see below).
* Doomie (voiced by [[Ron Rubin (voice actor)|Ron Rubin]] as Doomie, [[Colin Fox (actor)|Colin Fox]] as Dragster of Doom) – Beetlejuice and Lydia's convertible, neon-green-painted sentient car, (resembling a 1960s [[Plymouth Fury]]). The origin of his name is Lydia having desired to construct a "Dragster of Doom," though this title was only utilized in a single episode. Doomie is normally an affable and friendly creature, but due to the abnormal brain Beetlejuice gave him during his construction (ala [[Frankenstein's monster]]), Doomie transforms into a vicious "''four-wheeled [[werewolf]]''" type of monster in response to the presence of a Neitherworld dog near him, or to anger, fear, or the danger of his 'passengers', somewhat like a vehicular [[Dr. Jekyll and Mr. Hyde (character)|Jekyll and Hyde]] (correspondingly, even in his more sedate form he displays subtly dog-like traits such as panting, implying that he fills a pet-like role for Lydia and Beetlejuice). A recurring gag is for Doomie to turn into his "''werewolf stage''" to chase dogs around the Neitherworld, (a flip-switch to dogs chasing cars). In later episodes, he is known to "''speak''", which is given as the sound of an engine turning over in ignition. It is at these times, Lydia usually plays a translator for him, as we understand a more complex, benevolent, and hopelessly romantic side to Doomie, such as when he began courting Mayor Maynot's [[Convertible (car)|convertible]] Pinky. Beetlejuice makes a point of claiming his ownership over Doomie and often demands his loyalty whenever Doomie should contradict him or is needed to aide in Beetlejuice's endeavors. However, Beetlejuice can be greatly apathetic to any plight of Doomie's, necessitating Lydia's persuasion to help him.
* Barry MeNot (voiced by [[Keith Knight (actor)|Keith Knight]]) -– A CGI character who pops up in the Neitherworld's commercials to promote a product revolving around a plot point in a humorous side.
* Bea Juice (voiced by [[Susan Roman]]) -– The mother of Beetlejuice who is always picky about cleanliness.
* Nat Juice (voiced by [[Len Carlson]]) -– The father of Beetlejuice who is always trying to get Beetlejuice to find a job.
* Mayor Maynot (voiced by [[Len Carlson]]) -– The Mayor of the Neitherworld. In season one, he is a short green-skinned man in a top hat. In season two, he was redesigned to be a mummified monster of normal height. Mayor Maynot is always on Beetlejuice's case where he is always threatening to have him sent to Sandwormland.
* I.M. Smallhead -– The small-headed assistant to Mayor Maynot where he always agrees with him. While he is shown to dislike Beetlejuice, he can be friendly to him at times. I.M. Smalllhead is loosely based on Harry the Hunter from the live-action film.
* Judge Mental (voiced by [[Len Carlson]]) -– The Neitherworld's residential judge who would always threaten to sentence Beetlejuice to be condemned to Sandwormland when Beetlejuice ends up on trial in his courtroom.
* Mr. Monitor (voiced by [[John Stocker (voice actor)|John Stocker]]) -– A humanoid with four televisions for a head. He runs the Neitherworld TV Network where he is always keeping an eye on the ratings.
* Armhold Musclehugger (voiced by [[Keith Knight (actor)|Keith Knight]]) – First appeared in the fourth-season episode "Raging Skull"; a parody of [[Arnold Schwarzenegger]] (even speaking on a parody of Schwarzenegger's Austrian accent) and the former Mr. Neitherworld bodybuilding champion (until dethroned by Jacques, with some help from Beetlejuice). He is green-skinned with a blond crew-cut hairstyle and wears only bodybuilder briefs. As Mr. Neitherworld, he is extremely arrogant, but when he reappears in the episode "Goody Two-Shoes" he is more affable (while still proud of his physique). Later on, he becomes more toadying and goes to work for Chester Slime as his well-muscled right-hand man.
* Scuzzo and Fuzzo (voiced by [[Joseph Sherman]] and David Goldberg) – The [[Evil clown|trouble-making clowns]] and the rivals of Beetlejuice.
