List of SpongeBob SquarePants characters

Almost all of the SpongeBob SquarePants characters in the show.

The characters in SpongeBob SquarePants were created by artist, animator and former marine biologist Stephen Hillenburg. In addition to the series' main cast, various celebrities have voiced roles in SpongeBob SquarePants. Notably, Ernest Borgnine and Tim Conway voice the roles of recurring characters Mermaid Man and Barnacle Boy respectively, while others have taken a cameo part.

Creation and conception

Stephen Hillenburg conceived the characters for SpongeBob SquarePants in 1984, while he was teaching and studying marine biology at what is now the Orange County Ocean Institute. During this period, Hillenburg became fascinated in animation, and wrote a comic book entitled The Intertidal Zone starring various anthropomorphic forms of sea life, many of which would evolve into SpongeBob SquarePants characters, including "Bob the Sponge", who was the co-host of the comic and resembled an actual sea sponge as opposed to SpongeBob. In 1987, Hillenburg left the institute to pursue his dream of becoming an animator.

Main characters

• SpongeBob (Tom Kenny) is the series' title character and protagonist. He is a yellow sea sponge who physically resembles an artifical, rectangular, kitchen-type cleaning sponge; he wears brown short-pants, a white shirt and a red tie. He lives in a pineapple house and is employed as a fry cook at a fast-food restaurant called the The Krusty Krab, where many stories take place; he takes pride in his work and seems to worship or venerate the Krabby Patty. SpongeBob's hobbies include practicing karate with Sandy, as well as jellyfishing and blowing bubbles with Patrick. He attends Mrs. Puff's Boating School but has never passed; his lack of a driver's license is a running gag throughout the series. It is implied that, although he has no experience, he has talent in the arts. Green and purple were early color choices for the character before yellow was chosen. He is weak and fragile, shown in MuscleBob BuffPants when he can't lift a glass of tea, and he claims to be "pumping iron" with his plush toys. His first appearance was in "Help Wanted".

• Patrick (Bill Fagerbakke) is a sea star who lives under a rock and whose most prominent character trait is his low intelligence. He is friends with Spongebob and often encourages activities that get the two into trouble. While typically unemployed throughout the course of the series, Patrick holds various short-term jobs as the storyline of each episode requires. He is good-natured, kind, and is "the tough one" of the two who is often called to fight SpongeBob's battles for him (although he usually gets distracted). SpongeBob is the only character that Patrick shows any real emotions for. Patrick is shown to have a mean temper in some episodes and can only be calmed by his best friend's encouraging words. Despite being portrayed as a largely unintelligent character, it is mentioned in "The Bully" that he went to community college. He also seems to have short-term bursts of "knowledge"; he can sometimes show that he does have a brain. In the episode Patrick SmartPants, he refers to Spongebob and Sandy as "Robert" and "Sandra". His first appearance was in "Help Wanted".

• Squidward (Roger Bumpass) is an octopus with a large nose; he is SpongeBob and Patrick's ill-tempered, grouchy next-door neighbor with a snobby attitude. He plays the clarinet and loves to paint self-portraits in different artistic styles, which he hangs up around the walls of his house shaped like an Easter Island head-sculpture. He abhors SpongeBob and Patrick and would rather be a musician and painter instead of a cashier at the Krusty Krab, which is his current occupation.

• Mr. Krabs (Clancy Brown) is a red crab who owns and operates the Krusty Krab restaurant where Spongebob works. He is self-content, intelligent and loves money. He has a grandfather named Redbeard and lives in an anchor with his daughter Pearl, who is a whale. The Krusty Krab was originally a retirement home called "The Rusty Krab" which he bought after returning from fighting in the war; when it went bankrupt, he turned it into a restaurant and re-named it "The Krusty Krab". In some episodes, it is shown that he and Mrs. Puff have a mutual crush on each other. It is revealed in the episode "Sleepy Time" that he was born November 30, 1942.

• Sandy (Carolyn Lawrence) is a female squirrel from Texas. She has a number of athletic interests, such as "sand-boarding" and karate, and is a rodeo champion. She is also a scientist, explorer and inventor. Being from the surface, she lives in a tree which is inside a glass dome so she can breathe, and also wears a space-suit and helmet to travel outside of her tree-dome. Whenever any aquatic creatures enter her air-filled dome, they must wear helmets filled with water so that they can breathe.

• Plankton (Mr. Lawrence) is the owner of Chum Bucket, the rival restaurant to the Krusty Krab, and archenemy to Mr. Krabs. He constantly tries to steal the Krabby Patty Secret Formula, but is always unsuccessful (The one time he was successful was in The Spongebob Squarepants Movie). He wishes to rule the world. He has a computer wife, who is actually a W.I.F.E. (Wired Integrated Female Electroencephalograph). He is considered the main antagonists of the series

• Gary (Tom Kenny) is SpongeBob's pet sea snail. Within the series, snails are analogous to cats, so Gary almost always vocalizes like a feline. Despite this, other characters can understand and communicate with him. Depicted as a level-headed character, Gary sometimes serves as a voice of reason for SpongeBob, and solves problems that his owner cannot. He is sometimes nicknamed "Gare-Bear" by SpongeBob, and it is revealed in "A Pal for Gary" that his full first name is Garold.

Recurring characters

• Mrs. Puff (Mary Jo Catlett) - A pufferfish with blonde hair, who is the owner and teacher of a boating school (analogous to driving school, as the "boats" are underwater equivalents to cars). She dreads instructing SpongeBob due to his inability to drive without crashing. As shown in the episode "Krusty Love", Mrs. Puff once dated Mr. Krabs.
• Pearl Krabs (Lori Alan) is Mr. Krab's 16-year-old (as of the episode "Whale of a Birthday") sperm whale daughter. The series has yet to explain their disparity in species, although in the book SpongeBob's Trivia Book, Mr. Krabs explains that Pearl takes after her mother, meaning her mother was apparently also a whale. Pearl is frequently embarrassed by her father's cheap attitude, and often forces him to try and change his habits.
• Karen (Jill Talley) is Plankton's nagging computer "WIFE" (as in an acronym for "Wired Integrated Female Electroencephalograph"). She apparently has a mind of her own, to the point of making fun of Plankton. Karen usually helps Plankton in his schemes to steal the Krabby Patty secret formula although on occasions Plankton rejects her ideas and then takes them as if they were his own. It is revealed in The SpongeBob SquarePants Movie that she never agreed to marry Plankton. Karen also made a cameo in an episode of The Fairly OddParents called "Love Triangle". She is the monitor at the hospital after Poof catches a disease.
• Mermaid Man (Old: Ernest Borgnine, Young: Adam West) and Barnacle Boy (Old: Tim Conway, Young: Burt Ward) are two elderly and partially senile superheroes who live in a retirement home, whom SpongeBob and Patrick watch on television. Mermaid Man is the older of the two and is the leader, while Barnacle Boy is his sidekick. It is most likely that they are parodies of Aquaman and Aqualad, although the fact that their young versions are sometimes voiced by Adam West and Burt Ward, as well as the iconic use of onomatopoeic words, hints that they parody Batman and Robin. Mermaid Man is known for completely forgetting things, yelling "EVILLLLL!" whenever he hears the word, and Barnacle Boy seems to be the smarter of the two. It is implied in an episode that they are brothers. The male counterpart to a mermaid is a merman; Borgnine was briefly married to Ethel Merman.
• Larry the Lobster (Mr. Lawrence) is a lobster lifeguard of the Goo Lagoon. Larry is a bodybuilder and workout fanatic. He was considered a lifeguard on "SpongeGuard on Duty", but in other episodes, he is not and simply just hangs out at the beach. Despite his large and muscular physique, he is sometimes shown to be somewhat of a coward. He once overdosed on tanning pills. He also drives an SUV in one episode.
• Scooter (Carlos Alazraqui/Clancy Brown) - A lavender-colored fish who enjoys surfing. He allegedly died and became an angel in the second-season episode "Bubble Buddy", except he also returned in future episodes. Scooter talks like a stereotypical surfer dude, but after Season 3 he had different voices in each episode he appeared in. He is mainly seen at Goo Lagoon.
• Nat Peterson (Dee Bradley Baker & Tom Kenny) - A male yellow fish that is a common background character on the show. His last name is revealed in "Missing Identity" and his first name was revealed in "Plankton's Regular". He first apppeared on the fifth episode of SpongeBob SquarePants, "Ripped Pants", as a cameo. He appears in many episodes, especially the newer ones. His biggest role is in "Plankton's Regular".
• The Flying Dutchman (Brian Doyle-Murray) is an irascible pirate ghost named after a ghost ship, The Flying Dutchman. He lives underwater in a giant ship, and collects souls. He has supernatural powers, such was intangibility, levitation, teleportation, energy projection, shapeshifting, interdimensional travel, matter transmutation, and wish granting. He is known for having numerous awards in tying loops but however does not know how to tie shoelaces as reveald in " Loop De Loop" and hangs a sock on his ghostly tail. It is revealed in "Shanghaied" that he cannot eat without his sock.
• The French Narrator (Tom Kenny) speaks at the start of some episodes and during intertitles in American English with a French accent. He is sometimes shown in the series as a scuba diver with a TV camera, though he is normally speaking off-screen. On the November 16, 2004 episode of the NPR program Fresh Air with Terry Gross, Kenny admitted that Jacques Cousteau was the inspiration for the French narrator, as series creator Stephen Hillenburg considered him an idol.
• Patchy the Pirate (Tom Kenny) is a live-action character who is a pirate and the president of the SpongeBob fan club. He lives in the city of Encino, California. He is normally present in specials (one-off double length episodes), often in a dual narrative with the animated Spongebob, although sometimes he merely introduces the episode. He made a special guest star appearance on Big Time Rush in the episode "Big Time Beach Party" with Carlos Pena, Jr. and Logan Henderson. Patchy has a next-door neighbor named Mrs. Johnson who offers him cookies and has an electric wheelchair that goes really fast. Patchy works at a fast-food restaurant called The Poop Deck. His boss' name is Mr. Pirateson.
• Potty the Parrot (Stephen Hillenburg and Paul Tibbitt) is Patchy the Pirate's marionette parrot. He is shown to pull pranks on Patchy and shuns him at almost every episode they appear on. He is the assistant manager at The Poop Deck under Mr. Pirateson, the manager.
• Erain (Mr. Lawrence) is a live-action announcer and news anchorfish, resembling a cut-out of a bass fish. Erain appears in numerous episodes, including the beginning intro theme of the show. His name is revealed to be Erain in "The Great Patty Caper", though he is known as Johnny in Battle for Bikini Bottom.
• Harold SquarePants (Tom Kenny) and Margret Bubblebottem SquarePants (Sirena Irwin) are SpongeBob's parents, who more resemble sea sponges rather than SpongeBob's shape as a kitchen sponge. It is implied in the episode "A Squarepants Family Vacation" that Harold is not Spongebob's real father and could possibly be his stepfather.
• Squilliam Fancyson III (Dee Bradley Baker) is Squidward Tentacles's wealthy arch-rival who has been able to succeed in everything Squidward has only dreamed of doing. He and Squidward compete in the series on many reasons and Squidward normally does not win their competition(s), although there are some episodes where Squidward is triumphant.

• Man Ray (John Rhys-Davies & Guy Siner/Bob Joles) and the Dirty Bubble (Charles Nelson Reilly/Tom Kenny) are villains against Mermaid Man and Barnacle Boy. Man Ray (not the famous photographer of the same name) has a man's body with a ray shaped mask and helmet, while the Dirty Bubble is portrayed as a literal giant bubble with a face. Man Ray is based on Black Manta, Aquaman's archenemy. Charles Nelson Reilly was the primary voice actor for the Dirty Bubble, but Tom Kenny has portrayed the character in one episode after Reilly's death in 2007.

• Officers Nancy and John (Sirena Irwin & Dee Bradley Baker) – Officer Nancy (a purple female cop fish with blonde hair) and her partner John (an orange fish) are the two most commonly seen cops in Bikini Bottom, most prominently in Season 3.

He is friends with Mama Krabs as seen in "Sailor Mouth" and his first major appearance, "Friend or Foe?".
• Fred (Mr. Lawrence), better known as the guy who shouts "MY LEG!", is a brown fish who was the first of the regular generic character models to appear in the series. He first appears in "Reef Blower" but the famous quote does not come until "Boating School". Fred is most often seen at the Krusty Krab, such as in "Arrgh!", when he screams "MY LEG!" after Mr. Krabs throws him out of the Krusty Krab, and in "Jellyfish Hunter", when he sings about a jelly sandwich he eats. Fred's name is revealed in "Patty Hype". One of Fred's famous lines is "Rev-up those friers, 'cause I am sure hungry for a-" He is then interrupted by Mr. Krabs who says "Can't you see we're closed?!" In which Fred responds with the famous "MY LEG" line.
• Tom (Mr. Lawrence) – Tom is a green fish who wears a purple shirt. He is always seen walking around Bikini Bottom.

• Jack Kahuna Laguna (JKL) (Johnny Depp) – A surfer who prefers to be called JKL, and helps SpongeBob, Patrick and Squidward get home by teaching them how to surf.

• Dennis (Alec Baldwin (Mercenary) and unknown (SpongeBob's classmate)) – an assassin hired by Plankton to kill SpongeBob and Patrick in the movie.

He then pretends to be Spongebob's body guard, whom Spongebob thinks is protecting him from the strangler. He disguises his identity with a fake moustache.

At the end of the episode, he finds himself in prison and says he is happy to be 'safe from that yellow idiot' although he was sharing the jail cell with Patrick Star.

Reception

The characters of SpongeBob SquarePants have been well-received overall. The titular character SpongeBob has become very popular with both children and adults. The character's popularity has spread from Nickelodeon's original demographic of two to eleven-year-olds, to teenagers and adults, including college campuses and celebrities such as Sigourney Weaver and Bruce Willis. The popularity of SpongeBob translated well into sales figures. In 2002, SpongeBob SquarePants dolls sold at a rate of 75,000 per week, which was faster than Tickle Me Elmo dolls were selling at the time. SpongeBob has gained popularity in Japan, specifically with Japanese women. Nickelodeon's parent company Viacom purposefully targeted marketing at women in the country as a method of building the SpongeBob SquarePants brand. Sceptics initially doubted that SpongeBob could be popular in Japan as the character's design is very different from already popular designs for Hello Kitty and Pikachu. However, the characters have also attracted negative reception, including SpongeBob himself, who was listed as number four on AskMen's Top 10: Irritating '90s Cartoon Characters. SpongeBob SquarePants was ranked on TV Guide's top 50 cartoon characters.

Arthur Brown, author of Everything I Need to Know, I Learned from Cartoons!, has compared Squidward's voice to that of Jack Benny's.

Appearances in other media

The characters of SpongeBob SquarePants have been parodied various times in popular culture. In 2007, the Amsterdam-based company Boom Chicago created a SpongeBob parody called "Back to Work!" in which a Chinese Patrick refuses to go to work and advocates freedom of speech and rights of leisure and income. During the same year, production company Camp Chaos created a SpongeBob parody entitled SpongeBong HempPants which features five of the series' characters parodied in the form of various drugs. The series has received mixed reviews from television critics; Adam Finley of TV Squad believed the series sounded "hilarious on paper", but ultimately did not demonstrate its full potential. SpongeBob and Patrick have a root were also referenced in Phineas and Ferb when they dug a hole and found a sponge and a seastar. SpongeBob and Patrick also have an appearance in the Disney show Good Luck Charlie when Charlie's parents have a pink square and a yellow star puppet and are performing a potty training show on a fake television set.
