Eugene Harold Krabs (born November 30, 1942 ) 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.

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.

Mermaid Man is a semi-retired superhero living in Bikini Bottom.

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.

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.

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.

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.

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.

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.
