List of one-time The Simpsons characters

Further information: List of The Simpsons characters and List of recurring The Simpsons characters

The following is a list of one-time characters from the American animated television comedy series The Simpsons.

Some of the characters have returned to the show, sometimes in brief speaking appearances, or just 'in the crowd' scenes. Other characters originally intended to be one-time characters have ended up becoming regular cast members, such as Cletus Spuckler, Luigi Risotto, Disco Stu, Groundskeeper Willie, Crazy Cat Lady, Cookie Kwan and Lindsey Naegle.

For purposes of this list, "one-time" means they were central to an episode one time. Some of the characters listed here have appeared in later episodes, but only briefly. The characters are sorted by episode.

Series characters

Season 1

• "Simpsons Roasting on an Open Fire"
  • Mervin Monroe (Harry Shearer), a tattoo artist that almost gives Bart a tattoo that says "MOTHER" before Marge comes and stops him, leaving a heart and "MOTH" written on his arm. His brother is Marvin Monroe, who is later seen in "There's No Disgrace Like Home".
• "Bart the Genius"
  • Ms. Mellon (Marcia Wallace), teacher at a school for gifted children that Bart is sent to after cheating on an I.Q Test. She is the only character Marcia Wallace voiced other than Edna Krabappel.
• "The Call of the Simpsons"
  • Cowboy Bob (Albert Brooks), owner of Bob's Roundup RVs. He has non-speaking cameos after this episode, makes a brief speaking appearance in the season sixteen episode "Mobile Homer", and is seen in the episode "Bart Gets an F".
• "Life on the Fast Lane"
  • Jacques (Albert Brooks) is a bowling instructor who pursues an affair with Marge Simpson. Jacques has made non-speaking cameos in subsequent episodes, such as "Homer and Apu" (in the Monstro-Mart's line of single, pathetic men who only pay cash for their groceries and do not chat with the clerk) and "Homer's Triple Bypass" (in the waiting room with his bowling ball stuck on one of his fingers). He makes a quick appearance on the bowling team 'The Homewreckers' in "Team Homer", losing to Homer's team the 'Pin Pals'. He is also seen being startled by Bart on his skateboard (along with Bleeding Gums Murphy, Barney, Helen Lovejoy, Moe Syzlak, Chief Wiggum and Apu) in the opening credits of each episode (up until the middle of season 20, when the opening was changed for high-definition TV and the characters on the street were changed). He has a small speaking part in the beginning of Homer vs Lisa and the 8th Commandment, as 'Jacques the Adulterer'.
• "Homer's Night Out"
  • Gulliver Dark (Sam McMurray), a lounge singer and playboy. After Homer's speech about how women should not be seen or treated as sex objects, Dark decides to call his mother, as she sounded depressed the last time he called her. A man who looks and acts similar to Gulliver Dark is seen singing Tito Puente's fiery revenge song about Mr. Burns on the season seven premiere episode, "Who Shot Mr. Burns?" (Part 2).
• "The Crepes of Wrath"
  • Adil Hoxha (Tress MacNeille), a foreign exchange student from Albania who replaces Bart when he is deported to France. Although his good behavior fools Homer and Marge, Lisa is not deceived by Adil's charade and suspects he is up to no good. Her suspicion proves true, as he is actually an Albanian spy who plans to use Homer to gain blueprint information on a reactor for a nuclear power plant. Adil is returned to Albania in exchange for an American spy, also a child, caught in Albania. His last name is an unintentional reference to deceased Albanian leader Enver Hoxha, as stated by Al Jean in the DVD commentary for this episode.
• "Some Enchanted Evening"
  • Ms. Botz/Lucille Botzcowski (Penny Marshall) is an escaped criminal, known as "The Babysitter Bandit", who tries to rob the Simpson family, but is thwarted and captured by Bart, Lisa, and Maggie (the kids nearly torture her into insanity by making her watch "The Happy Little Elves"). Before she is revealed on a television show, America's Most Dangerous, Ms. Botz is able to put Bart in his place due to her dealing with previous troublesome children. She deceives Homer into freeing her moments before the police arrive. In "Bart's Dog Gets an F" a news broadcast mentions that she has escaped from prison. In "Hurricane Neddy" she has a non-speaking cameo as a patient at Calmwood Mental Hospital; and also appears in a cameo in Family Guy episode The Simpsons Guy.

After arranging a date for Bea's birthday, Grampa was forced to stand her up when Homer took him to "Discount Lion Safari". When he returned to the Retirement Castle, Bea had died and left all her money to Abe. It was Bea's death that made Abe resent Homer for his actions and eventually used the money to renovate the retirement home, dedicating the dining hall in her name.
• "Brush with Greatness"
  • Professor Lombardo, (Jon Lovitz) an art teacher at Springfield Community College. He is quick to compliment almost everything he sees as art. However he does not take praise very well. He reappears briefly in "The Ziff Who Came to Dinner" as part of a quartet of Simpsons characters who were voiced by former SNL cast member Jon Lovitz.
• "Lisa's Substitute"
  • Mr. Bergstrom (Dustin Hoffman, credited as "Sam Etic") was Lisa's substitute teacher. Mr. Bergstrom took over for Ms. Hoover after she believed she had got Lyme disease and Lisa immediately took to him because he was the kind of male role model she needed in her life. However, after Ms. Hoover returned, he had to leave Springfield. A distraught Lisa ran to stop him, and Mr. Bergstrom gave her a note saying "You are Lisa Simpson". He later makes a brief non-speaking appearance in the 25th-season episode "The Kid Is All Right" and in season 27 in the episode "Friend with Benefit".

Season 3

• "Stark Raving Dad"
  • Leon Kompowsky (voiced by Michael Jackson, Kipp Lennon and Hank Azaria) was a mental patient who pretended to be Michael Jackson. The character was voiced by Michael Jackson (who, for contractual reasons, was credited as "John Jay Smith"). The producers of the show were legally prevented from confirming Jackson guest starred at the time, although many media sources (correctly) assumed it was really him. A year after the episode aired, the writers decided to make a sequel where Leon Kompowsky returns, thinking he is the musician Prince (and voiced by Prince himself), who encourages everyone in town to be sexually liberated, but it was scrapped when Prince declined.
• "Mr. Lisa Goes to Washington"
  • Bob Arnold (Hank Azaria) was a corrupt Congressman. He accepted a bribe to demolish Springfield National Forest, but was overheard by Lisa Simpson, and was later caught and arrested after she exposed him while making her speech along with a sexist comment he made about a feminist statue.
• "Homer Defined"
  • Aristotle Amadopolis (Jon Lovitz and Dan Castellaneta) is the wealthy owner of the Shelbyville Nuclear Power Plant. He was originally voiced by Jon Lovitz, but would have a brief speaking part voiced by Dan Castellaneta in "Homer at the Bat".

• "Treehouse of Horror II"
  • Crippled Merchant (Hank Azaria) is a Moroccan street vendor who sells Homer a monkey's paw. He was once the President of Algeria because of a wish he made on the paw. He warns the Simpsons not to use the paw to make their wishes unless they want to suffer great misfortune. Out of the Simpsons, only Marge heeded the merchant's warning.
• "Flaming Moe's"
  • Collette (Jo Ann Harris), a waitress hired by Moe because of her moxie. Catherine O'Hara originally agreed to do the voice and recorded her part for the character; however, the producers felt that her voice did not fit the role and instead had Jo Ann Harris do the part.
• "Burns Verkaufen der Kraftwerk"
  • Horst (Phil Hartman), Hans (Hank Azaria), and Fritz (Harry Shearer) were three German businessmen who bought the Springfield Nuclear Power Plant from Mr. Burns. However, they abandoned the venture and settled to sell the plant back to Burns for half of what they paid after they found out about the true safety and working conditions.
• "Bart's Friend Falls in Love"
  • Samantha Stanky (Kimmy Robertson) is a girl with orthodontic braces from Phoenix, Arizona who moves to Springfield and starts school at Springfield Elementary School.

Season 4

• "Kamp Krusty"
  • Mr. Black (Harry Shearer) was Krusty's accountant and the evil camp director of Kamp Krusty who hires local thugs Dolph, Jimbo, and Kearney to be counselors to break the kids' spirits (which does not work when Bart leads an insurrection against them). He promptly flees on a hydrofoil, never to be seen again. Mark Kirkland was sure that the character was going to reappear later in the series, but he never did. However, he appears in a comic book based on the series where he has Homer sell him a company while "filling in" for Moe, who was literally tied up down in his basement.
• "A Streetcar Named Marge"
  • Llewellyn Sinclair (Jon Lovitz) is an intense, short-tempered perfectionist who works as a theater director. He boasts of the multiple heart attacks he has suffered for his work. He casts Ned Flanders as Stanley Kowalski and Marge as Blanche DuBois in a production of A Streetcar Named Desire. Sinclair has since made brief cameo appearances and appeared in a crowd shot in "Sweets and Sour Marge". He also appeared with speaking parts in "I'm Just a Girl Who Can't Say D'oh".
• "Lisa the Beauty Queen"
  • Amber Dempsey, (Lona Williams) a professional child beauty queen who once won Pork Princess and Little Miss Kosher in the same week. She has eyelash implants (which are only legal in Paraguay) and is referred to by Lisa as "the Jack Nicklaus" of the pageant circuit (not because they're attractive, but because they both win all the time). Amber wins The Little Miss Springfield Beauty Pageant, but the crown is turned over to Lisa (the first runner-up) after Amber gets struck by lightning during a store opening. She is hospitalized and quickly becomes "Little Miss Intensive Care".
  • Jack Larson (Harry Shearer), is president of Laramie Cigarettes, and once owned the Springfield Isotopes. He also was the spokesperson in a commercial for the Little Miss Springfield pageant, with Laramie cigarettes as the main sponsor.
• "New Kid on the Block"
  • Laura Powers (Sara Gilbert) is the teenage daughter of Ruth Powers. Her first and only speaking appearance is when her family moved next door to Bart after the elderly Winfields moved out. Bart developed a crush on her, but ended up in heartbreak when he found out her boyfriend was Jimbo Jones, whom she later breaks up with after Moe threatens to kill him over a prank call that Bart made and Jimbo breaks down sobbing. Ruth mentions Laura in "Marge On The Lam"
• "Marge vs. the Monorail"
  • Lyle Lanley (Phil Hartman) is a smooth talking con man who uses songs to convince the people of Springfield into buying an expensive monorail after Mr. Burns was fined $3 million. However, Lyle finds an enemy in Marge, the only resident who opposes it. Suspecting he had an ulterior motive, she discovers his plans in using the money he skimmed from the shoddily-built monorail to go on vacation without concern for the Springfieldianites. However, an angry mob of North Haverbrook residents attack him during an unexpected flight layover, their city having previously fallen for his monorail scam. The character is based on Harold Hill, the main character from the 1962 film The Music Man.
  • Sebastian Cobb (Harry Shearer) A German scientist living in North Haverbrook who built the monorail for Lyle Lanley. Like Marge, he opposed the building of the monorail.
• "Brother from the Same Planet"
  • Tom (Phil Hartman) is Bart's "Bigger Brother". Bart decides to get a bigger brother after Homer failed to pick him up from soccer practice. At the aquarium, Homer got into a fight with him. At the end of the episode, he became Pepi's big brother. The part was written for Tom Cruise, but Cruise declined so the role was given to Phil Hartman instead.
  • Pepi (Tress MacNeillie) is a poor boy who lives in Springfield and becomes Homer's 'Little Brother'. At the end of the episode, he becomes Tom's 'Little Brother' after Homer and Bart reconcile.
• "I Love Lisa"
  • Sideshow Raheem (Michael Carrington): the militant black Sideshow partner Krusty had on his show in the 1970s. Has an Afro and wears a dashiki and dark sunglasses. Was seen at Krusty's funeral on "Bart the Fink".
  • Rex (Michael Carrington): a melodramatic boy in Lisa's class who auditioned to play George Washington during the school's Presidents' Day pageant. Although impressive, he was turned down for Ralph Wiggum by Ms. Hoover (so she can have the Denver boot removed from her car tire) and tried to claim it was fair. Rex suspected that Ralph only won the lead role because of his father's position as the Springfield Police chief and resented being cast as George Washington's butler who appeared near the end of the performance. Another boy with a similar personality to the Rex in this episode appeared in season six's "Bart of Darkness," but his appearance was drastically altered, looking somewhat like Hugh Parkfield, the Englishman Lisa almost marries in "Lisa's Wedding."
• "Last Exit to Springfield"
  • Dr. Wolfe (Hank Azaria) is the intimidating and judgmental dentist that the Simpson family visits. Anthony Perkins had agreed to voice Dr. Wolfe, but unfortunately fell ill and could not record the part. Clint Eastwood and Anthony Hopkins had also been asked to provide a voice, but both declined. Perkins was then asked and while he expressed interest, he died before recording. The role went to Azaria.

Season 5

• "Homer's Barbershop Quartet"
  • Nigel (Harry Shearer) An Englishman and manager of the Be-Sharps. He suggested the band should replace Chief Wiggum with Barney Gumble because the former was "too Village People", and convinced Apu to adopt the stage name Apu de Beau Marchais. He pushed the group to choose a name and go public.
• "Treehouse of Horror IV"
  • The Gremlin (Frank Welker) is a gremlin who, in a parody of The Twilight Zone episode "Nightmare at 20,000 Feet", attacks a school bus going to Springfield Elementary School with Bart Simpson being the only person who notices it.
• "Homer Goes to College"
  • Dean Bobby Peterson (Hank Azaria) Dean of Springfield Community College. Homer psychologically projects onto him the role of an uptight, intolerant dean that he's seen in film, despite Peterson's friendly and laid-back demeanor, even forgiving Homer for hitting him with his car. The character made a brief speaking appearance in the episode "Faith Off" looking and acting completely different.
• "Bart's Inner Child"
  • Brad Goodman (Albert Brooks) is a self-help guru. After talking to Bart Simpson during a lecture at Springfield, he encourages the town to be more like Bart and to "do what you feel like", which eventually causes disastrous consequences. The people of Springfield go so far as to construct a golden statue of him in a parody of the biblical golden calf. His is the third character to be voiced by Brooks in the show.
• "The Last Temptation of Homer"
  • Mindy Simmons (Michelle Pfeiffer) is a former employee of Springfield Nuclear Power Plant, for whom Homer had an attraction. According to Homer on "Another Simpsons Clip Show", Mindy "hit the bottle pretty hard" and allegedly lost her job at the plant, however she has still been used as a background character at the plant in subsequent episodes (such as "The Twisted World of Marge Simpson"). She also appears in "Team Homer" as a member of the "Home-Wreckers" bowling team, which consists of another women with whom Homer almost had an affair: an aspiring country singer (Lurleen Lumpkin in "Colonel Homer"); an exotic dancer Homer once cavorted with at a bachelor party, creating a rift between him and Marge (Shauna Tifton, aka "Princess Kashmir" in "Homer's Night Out"); and Jacques, a bowling instructor who nearly seduced Marge ("Life on the Fast Lane").

  • Stacy Lovell (Kathleen Turner) is the inventor of Malibu Stacy. Was fired in 1974 for funneling profits to the Viet Cong and because "her way of thinking wasn't cost-effective". She lives in an exact replica of her Malibu Stacy Dreamhouse in a neighborhood for recluses and once dated an African-American man who looks like a G.I. Joe action figure.
• "Deep Space Homer"
  • Buzz Aldrin (Buzz Aldrin) is a former astronaut who aided Homer and Race Banyon on their space mission.

He reappears in "Trash of the Titans" as one of the people in line at the courthouse to register as a sex offender (along with Patty and Selma, Jimmy the Scumbag from "Lisa's Date with Density," and Moe, who complains about how long the sex offender line always is) and later in "See Homer Run" (with a somewhat altered voice and appearance) as his uncle's press secretary.
  • Clumsy Waiter (Hank Azaria), is the French waiter who Freddy mocks due to his accented version in pronouncing Chowder. He sues Freddy out of revenge and under the guise that he was assaulted. At risk of being exposed for skipping school by Skinner, Bart gives out his testimony that Freddy is innocent and the waiter is clumsy. The waiter tries to deny this, but trips and falls outside on a truck housing mouse traps, proving Bart's theory true.

Season 6

• "Itchy & Scratchy Land"
  • Bort, a churlish patron of Itchy & Scratchy Land's gift shop, who coincidentally shares his name with the son of a woman he encounters (as well as innumerable other park enthusiasts, given the wild popularity of the novelty license plates bearing the name on the park's souvenir racks to the point of them having been sold out).
• "Bart's Girlfriend"
  • Jessica Lovejoy (Meryl Streep) is the daughter of Timothy and Helen Lovejoy. Initially appearing as a calm, sweet girl back from boarding school, she also enjoys causing mischief, but reveals that she is even more of a wild misfit than Bart; she was actually expelled for destroying school property, stealing and starting up fights. Wooing Bart the first day they met, she soon became his girlfriend, but later revealed a manipulative femme fatale side. Though she only had one major role on the show, she appeared many other times in Simpsons Comics such as when she became fat (along with the rest of Springfield Elementary because Nelson stopped bullying).
• "Homer Badman"
  • Ashley Grant (Pamela Hayden) is a feminist graduate student who babysits Bart, Lisa, and Maggie. She falsely accuses Homer of sexual harassment (albeit unwittingly) after she mistakes his reaching for the candy Venus de Milo stuck to her rear end (complete with drooling) for a sexual attack, prompting a protest and media circus against Homer. Ashley forgives Homer (and vice versa) after she is shown video evidence of his innocence.
• "Fear of Flying"
  • Dr. Zweig (Anne Bancroft) is a psychologist who tries to help Marge get over her fear of flying. She appears as one of the judges at Marge's insanity hearing in "It's a Mad, Mad, Mad, Mad Marge". While a competent psychologist, she is somewhat hypocritical as she, as Homer predicted and feared, immediately suspects Homer of responsibility for Marge's problems, despite her statement that she was not there to cast blame on anyone. However, in "It's a Mad, Mad, Mad, Mad Marge", she and her colleagues are somehow completely ignorant of the ubiquitous concepts of religious belief and prayer, instead interpreting Marge's prayer to God and belief in his omnipresence as symptoms of schizophrenia.
  • Guy Incognito (Dan Castellaneta) is a seemingly upper-class man who is identical in appearance to Homer Simpson. After Homer is banned from Moe's Tavern, Guy Incognito appears at the bar and introduces himself. He is mistaken for a badly disguised Homer and is subsequently beaten up and thrown out of the bar only to have the real Homer walk past him.

She is seen briefly when Smithers phones to tell her she has a call waiting from her son, who she refers to as "that improvident lackwit", but Homer accidentally cuts her off before they can speak.

Season 8

• "You Only Move Twice"
  • Hank Scorpio (Albert Brooks) is an evil genius and supervillain. He is also the cheerful, friendly owner of Globex Corporation. Scorpio is considered by some to be Albert Brooks' best voice performance on The Simpsons and for this and four other guest performances he was named the greatest guest star in the show's history by IGN. Brooks ad-libbed many of his lines. He was supposed to be the main villain of The Simpsons Movie, but the character was replaced with EPA chief Russ Cargill (also voiced by Brooks) by the writers.

He later appears in the unemployment office in "Realty Bites".
• "Bart After Dark"
  • Belle (Tress MacNeille) the owner of the Maison Derrière, a local burlesque house where Martha Quimby met her husband, Mayor Quimby.

• "Hurricane Neddy"
  • Dr. Foster (Hank Azaria), Ned's psychologist as a child who treated Ned in the Calmwood Mental Hospital after his breakdown. He appears again at Marge's competency hearing in "It's a Mad, Mad, Mad, Mad Marge" in a younger form.
• "El Viaje Misterioso de Nuestro Jomer (The Mysterious Voyage of Homer)"
  • The Space Coyote (Johnny Cash), a coyote who appeared in Homer's chili-induced hallucination and set Homer on a quest to find his true soulmate. In his book Planet Simpson: How a Cartoon Masterpiece Documented an Era and Defined a Generation, Chris Turner states that Johnny Cash as the coyote is his favorite guest performance. The Coyote is briefly glimpsed again in the 26th-season episode, "Blazed and Confused", by Marge this time while she is having chemical-induced hallucinations.

  • Shary Bobbins (Maggie Roswell) is a magical British nanny modeled after Mary Poppins and hired to care for the Simpson children after Marge is revealed to be going bald from stress. After realizing she can never make The Simpsons functional, Bobbins flies away, and (unknown to the rest of the family) dies when she gets sucked into the jet engine of an airplane. She reappears in a cameo in "Treehouse of Horror XXV", and possibly among a bunch of flying nannies glimpsed in "The Regina Monologues", and on the opening sequence of the 2nd and 6th episodes of the 21st season, "Bart Gets a 'Z'" and "Pranks and Greens".
• "The Itchy & Scratchy & Poochie Show"
  • Roy (Hank Azaria), a young adult who briefly lives with the Simpson family. Before his introduction Lisa states "Adding a new character is often a desperate attempt to boost low ratings." At the end of the episode he leaves the Simpson house to live in an apartment with two sexy ladies. Before production began, a Fox executive suggested the staff add a new character to the show, who should come and live with the Simpsons on a permanent basis because it would "liven up the show". The staff rejected the idea. Instead they inserted the one-time character Roy, with no explanation as to who he was or why he was there. Roy's appearance, mannerisms, and role all resemble that of episode-centric Itchy and Scratchy character Poochie. This was as a reference to the executive's proposal (and a meta-joke about long-running shows bringing in annoying characters to boost ratings). Roy was originally conceived for the "Time and Punishment" segment of the season six episode "Treehouse of Horror V", living with the Simpsons in an alternate reality where Homer has an annoying teenage son.
  • While Springfield Elementary students are watching a potential cartoon series, a muscular man in a Speedo capriciously walks onto the screen and starts flexing. Nelson Muntz made it seem like Milhouse van Houten enjoyed seeing him. This upset Milhouse. Roger Meyers Jr. says, "One kid seems to love the Speedo Man." The character may have been based upon the He-Man cartoon character.[1]
• "Homer's Phobia"
