Characters

SpongeBob SquarePants is an optimistic and friendly sea sponge who works at the Krusty Krab, attends boating school, and hangs out with his friend Patrick, or spends time with his crush, Sandy.

Patrick Star is SpongeBob's best friend, who is a starfish. He is known to not do anything and always forgetful, and usually gets SpongeBob mixed into his situations. Patrick is quite overweight and loves ice cream and many other junk foods. He lives under a rock. SpongeBob and Squidward are his neighbors. 

Squidward Quincy is the middle neighbor between SpongeBob and Patrick Star. Squidward is a cephalopod. His species is an octopus according the series' creators, despite his name containing "squid". Squidward lives in a house shaped like an Easter Island Head (Moai head). He works as a Cashier at the Krusty Krab, a job he dislikes. SpongeBob works along with Squidward at the Krusty Krab. Squidward is a selfish individual and displays an unjustified air of superiority. He also has over 500 self-portraits and is delusional about his talents (such as playing the clarinet) though nobody around him considers him to be very good. The series' animators made Squidward with six tentacles, believing that giving him the eight tentacles of an octopus has made him look too burdened.  he has a deep interest in the arts, believing that the other Bikini Bottom residents are uncultured.

Sandy's real name is Sandra Cheeks.She is a squirrel and one of SpongeBob's best friends. Sandy is notable for her Texan characteristics and knowledge of Karate and science. As revealed in Patrick SmartPants and Atlantis SquarePants. 

Gary Wilson Jr. is SpongeBob's loyal pet, although his behavior in several aspects resembles a snail. He is known to love books and other educational stuff and is more mature than Squidward. He also hates taking baths as shown in "Gary Takes a Bath". Gary is shown to be very bored and massively cheeky.

Eugene Harold Krabs (born November 30, 1942 [1]) better known as simply Mr. Krabs or called Krabs by Plankton is a Crimson sea crab who is the owner of the Krusty Krab as well as the employer of both SpongeBob SquarePants and Squidward Tentacles. Creator Stephen Hillenburg describes Krabs as another main antagonist of the series. He is extremely greedy, selfish and quite literally obsessed with money itself. Mr. Krabs is mostly respected by SpongeBob, while Squidward tends to loathe him. Mr. Krabs' greed in the series is exaggerated with him often anthropomorphizing money. He will do almost anything to obtain money or not lose it, usually with no regard to the safety or well-being of others or even himself. His arch-nemesis and business rival is Sheldon J. Plankton, who was his friend in their childhood but now constantly attempts to steal the Krabby Patty Secret Formula. Mr. Krabs has a daughter, a sperm whale named Pearl. Since the beginning of the series, Mr. Krabs' overall characterization has become more and more negative, to the point that Stephen Hillenburg himself once said in an interview that he and Plankton are both the primary antagonists (in some episodes) of the show, with Mr. Krabs being just as bad, if not worse than, Plankton himself.

Pearl Krabs is a fictional character in the Nickelodeon animated series SpongeBob SquarePants. She is the daughter of Eugene H. Krabs and voiced by Lori Alan.She is a recurring character who was most notably seen in the episode Bossy Boots. She is a whale, so it is unknown whether she was adopted or if Mr. Krabs was once married, and her mother was a whale. She is revealed to be sixteen years old in Whale of a Birthday. She always get what she wants, if she can't get anything, she cries.

Sheldon James Plankton is Mr. Krabs' arch nemesis and the antagonist in the SpongeBob SquarePants series. He was the main antagonist in the movie, "The Great Patty Caper", "SpongeBob's Last Stand", "Truth or Square", "Atlantis SquarePantis", and "Frozen Face Off" and a protagonist villain in episodes he leads/really focusing to him and a non-villain in episodes when he wasn't portrayed as an antagonist/villain.He operates a struggling restaurant called the Chum Bucket, located directly across the street from the Krusty Krab. His primary goal in the series is to steal the Krabby Patty secret formula and put Mr. Krabs out of business. Plankton succeeds at stealing the recipe in the movie, but his goal of world domination is thwarted by SpongeBob. In "Friend or Foe," it was revealed that Mr. Krabs and Plankton were once best friends, but a dispute over the Krabby Patty recipe ended their friendship.

Karen Plankton is Plankton's wife. She is usually smarter than plankton. A Mark II UNIVAC, she is the main computer system of Plankton's lab, and is often the source of his plots (even though Plankton takes all the credit). She is voiced by Tom Kenny's wife, Jill Talley. Karen usually manifests on the large-screen computer in Plankton's lab, but sometimes acts through a portable wheeled computer. She was first shown in the episode "Plankton!", although in her first appearance she was simply Plankton's talking computer and would not be established as his wife until later on. In the episode Friend or Foe, it was discovered that Karen was a Security System before Plankton married her.

Larry the Lobster is a muscular red lobster who is a common patron and lifeguard of Bikini Bottom's popular beach, Goo Lagoon. He is a minor supporting character who is seen interacting with SpongeBob, or other characters in the series. He is voiced by Doug Lawrence. Larry first appeared in the episode "Ripped Pants". Although he appears in many episodes, Larry is a relatively minor character in the series, usually relegated to minor or background roles.

Mable Lobster/Jenkins is an elderly woman at Shady Shoals that's seen in a purple dress and usually carries a cane. She has been married to Old Man Jenkins or Dennis Rechid, with whom she had with Larry the Lobster. In "Shuffleboarding" she does laundry and talks to Man Ray and states that they met in high school. In the movie, she calls SpongeBob a "KnuckleHead McSpazzatron". She also appeared in "Keep Bikini Bottom Beautiful", in which she thinks that Squidward is the trash man.

Old Man Jenkins (Jensen) is an elderly fish. His name is a character name used in various episodes as a running gag. The name was originally applied to the elderly green fish in the image above, who appears commonly throughout the series, but in other episodes the name "Old Man Jenkins" has been used for completely different characters, although they are always elderly fish. His first name is unknown . He has been voiced by both Tom Kenny and Doug Lawrence. In the very recent episode called "The Main Drain", he appears as the image below except he is more short and green.

Mermaid Man is a semi-retired superhero living in Bikini Bottom. He and his sidekick, Barnacle Boy, are the stars of a show-within-a-show called The Adventures of Mermaid Man and Barnacle Boy, but they are also real superheroes within the universe of SpongeBob SquarePants. The two are now very old, and currently reside at Shady Shoals Rest Home. However, their two biggest fans, SpongeBob SquarePants and Patrick Star, convinced them to come out of retirement. He is voiced by Ernest Borgnine.

"Barnacle Boy" has been the sidekick of Mermaid Man and appears to be Patrick Star's favorite superhero. He is voiced by Emmy Award-winning comedian and actor, Tim Conway. He, along with Mermaid Man, are superheroes. He is a parody of both Aqualad and Robin. Barnacle Boy was said to be 68 years old in "Mermaid Man and Barnacle Boy V".

Mrs. Poppy Puff is a recurring character in SpongeBob SquarePants. Her occupation is to teach her students driving lessons at her boating school. SpongeBob has attended the school ever since its opening, and has failed his final driving exam countless times, often injuring Mrs. Puff and/or damaging the school in the process. Mrs. Puff hates teaching SpongeBob more than anything in her ocean world.SpongeBob SquarePants, Mrs. Puff's longest-standing student, is the bane of her existence. His distracting personality, reckless driving and inability to improve torment her to no end. SpongeBob has failed his driving test countless times, often sending Mrs. Puff to the hospital and causing immense property damage in the process. On multiple occasions, she has been sent to jail as a result of his actions. To make matters worse, SpongeBob has failed to come to terms with the reality that he cannot learn to drive properly, largely due to his boundless optimism. Due to this, she and Squidward Tentacles are on very good terms for good or evil, since SpongeBob is also Squidward's bane of existence, so she has someone to relate to. However, in comparison to Squidward, she is much kinder to SpongeBob (probably stemming from their teacher/student relationship); for example, while Squidward usually tells SpongeBob face-to-face that he hates him, Mrs. Puff has at least tried to hide her fury. Also, she has even acted nice to SpongeBob on some occasions, like in the episode Krusty Love, she showed no annoyance or anything negative to him, except when she screamed in horror when she thought they were doing the boating test, and the second time, when she's on her second date with Mr. Krabs, he states SpongeBob is helping him tonight, she says slightly worried, "Just a second. I need to go call my insurance agent".

Squilliam is rich, fancy, and prissy. He acts more mature than Squidward, but makes no secret of the fact that he considers himself superior to others due to his enormous wealth. He is a mean, selfish, and arrogant octopus who takes great pleasure in asserting his perceived superiority over middle-class citizens like his arch-rivalSquilliam in underwear.Added by SanseiXSquidward. He also speaks in a very mocking tone, placing great emphasis on his low regard for Squidward and an equally large amount of inflated praise in his lavish lifestyle. Despite his selfish personality, he somehow makes friends easily (probably for letting people in his private jet, yacht, airship/casino, etc). He, somehow, even make friend with SpongeBob.

The Flying Dutchman is a recurring character in SpongeBob SquarePants. He is a green pirate ghost who haunts Bikini Bottom. When he had died, he had no funeral because his body was used as a window display. Now he haunts the Seven Seas because he was never put to rest. He expresses a dislike for the tradition in which others dress up as him for Halloween and claims that it "turns the Flying Dutchman name into a laughing stock"

King Neptune (5,000 years old), is the series' depiction of Neptune, the Roman God of the sea. In the universe of SpongeBob SquarePants, Neptune is the god and supreme ruler of the sea. His name is often used in place of God's, with phrases such as "Dear Neptune" and "Neptune preserve her!". However, he has never explicitly been shown to be worshiped by the creatures of the sea. King Neptune first appeared in the episode "Neptune's Spatula", while a completely different looking Neptune appeared in The SpongeBob SquarePants Movie. Then the same Neptune from Neptune's Spatula appeared in Clash of The Triton. Neptune is voiced by John O'Hurley in the TV series, and by Jeffrey Tambor in the movie. His Greek counterpart is Poseidon. He was 5,000 in "The Clash of Triton", and he is now 5,001 years old.

Princess Miranda "Mindy" Neptune is the daughter of King Neptune and Queen Amphitrite and is Prince Triton's sister. She knows all the names of the sea creatures. It is also certain that King Neptune will crown her Queen of the Sea one day. She is known to use "Mermaid Magic" to help Bikini Bottomites over come the fears. There really is not any mermaid magic. Mindy tried to get SpongeBob and Patrick to keep going when they gave up their walk, she tried to convince them that she had "mermaid magic" (which obviously wasn't real), and used it to "turn them into men" by pulling seaweed out of the ground and putting them on their noses, successfully helping them by tricking them into thinking that they were real mustaches. Dennis revealed the trick after SpongeBob and Patrick passed through the trench. Mindy is very beautiful and good-hearted.

Scooter Rechid is a surfer fish commonly seen at Goo Lagoon who is easily identified by his high-pitched, shaky voice. Scooter has green lips and wears green or purple shorts with yellow flowers. His girlfriend is Nazz, whom he has a baby with. He is usually voiced by Carlos Alazraqui, but is voiced by Clancy Brown in the episode "Wigstruck".He once died, when he drowned in the high tide in Bubble Buddy, but he may have remained alive afterwards.

Puffy Fluffy is a character that only appears in A Pal for Gary. He is a nudibranch (although not resembling an actual nudibranch at all). SpongeBob bought him so that Gary wouldn't be lonely while he was at work, but he turned out to be a monster. SpongeBob was ignorant of the situation and failed to notice anything wrong with Puffy Fluffy, even after seeing its monster form, while Gary was wrapped up by its tongues and was about to be eaten. SpongeBob was also about to be eaten but remained oblivious, even after Gary saved him. Puffy Fluffy ran away after Gary tied up its tongues together with a leash and Spongebob blamed Gary by making Puffy Fluffy ran away.

Painty the Pirate, also referred to as Captain, is a painting of a pirate head with his parrot which appears at the beginning of, and sings the SpongeBob SquarePants Theme Song. His mouth is actually real, so he could talk. The real lips in the painting are the lips of Stephen Hillenburg, the show's creator. He also makes appearances in "Your Shoe's Untied" and "Wet Painters" (although in the latter he only appears as an inanimate painting). He has a patch over his left eye, a skull-and-crossbones hat, and of course the parrot on his left shoulder. He is voiced by Patrick Pinney in most appearances, but in Truth or Square, in the "rejected" theme songs (Squidward Tentacles, Patrick Seastar, and Eugene Krabs versions, all posed by Patchy the Pirate), he is voiced by Bob Joles. On the ride SpongeBob 4D formally at Kings Dominion, was previously at Six Flags: Great Adventure, but now in Adventure Aquarium in Camden, New Jersey. Painty would come out of the screen to "drag" the viewers underwater. Unfortunately, this scared many children who had to leave the ride.

Potty the Parrot is Patchy the Pirate's pet parrot. Potty is a crudely made puppet with very obvious strings. He is very obnoxious, and normally annoys and talks back to Patchy. Potty was originally portrayed by Stephen Hillenburg. After his departure, Paul Tibbitt was given the role. His first appearance was in Christmas Who? and his last appearance was in The Sponge Who Could Fly. Also, it should be noted that in The Sponge Who Could Fly, when Potty is dropping an egg in Patchy's remote control, whether he gets it from the refrigerator, or he is actually a she.

Man Ray is the archenemy of Mermaid Man and Barnacle Boy. He is a parody of Aquaman's arch villain, Black Manta. He was originally voiced by John Rhys-Davies, but later replaced by Bob Joles. Man Ray is an anthromorphized Manta Ray with a blue helmet shaped like the head of a manta ray and red skin. His gloves, boots, and speedo are a deep blue color. He has no head under his helmet.

Johnny Erain is the realistic fish head who frequently announces/hosts various news reports and other events in Bikini Bottom. But his name has been rumored to also be named Elaine after Perch Perkins called him that at the beginning of "Frozen Face-Off." He also sings in the SpongeBob SquarePants theme song. His name was revealed in the Battle for Bikini Bottom video game, where he is the announcer for the main boss fights.Johnny has also been the announcer at other events, such as the 21st Fry Cook Games. He was the narrator of the King of Karate video in "Karate Island", and voiced the loudspeaker at the Bikini Bottom Zoo in "The Smoking Peanut". In addition to announcing events in Bikini Bottom, Johnny also serves as a news anchorman for the Bikini Bottom News. Most of the news reports he gives are regarding disasters in Bikini Bottom, such as in "Wormy", where he warns the town about the "monster", and in "Nasty Patty," when he reports the warning of a man who pretends to be a health inspector to obtain free food.The only times where he has ever interacted with the main characters (as he usually only appears on a screen) are in "No Free Rides" and "Procrastination", and both of these were during dream/fantasy sequences. His voice is often heard when he himself is not shown, so it is uncertain if he is speaking during these instances, as in "No Free Rides" and "Suction Cup Symphony", his voice is different from his usual one. He also appears during the theme song, when the line "Then drop on the deck and flop like a fish" is sung. He is voiced by Doug Lawrence, except for "Suction Cup Symphony" and "No Free Rides" where he was voiced by Tom Kenny.In "The Fry Cook Games" he actually mentions that he is a realistic fish head.
