Mr. Krabs/Synopsis

Biography
Eugene Harold Krabs was born with the blood of a pirate. His grandfather, Redbeard the pirate, mostly taught and raised him. During his preteen years, he took over the family ship, the Krusty Krab. However, he realized he was not making a profit, so he decided to run away with his grandfather's last words haunting him, "A pirate never lies". He then joined the Pacific Navy. Krabs earned the nickname Armor Abs Krabs, and the title of being the manliest of the crew. His shipmates were Torpedo Belly, Mutton Chop, Iron Eye, and Lockjaw Jones. Krabs's manhood began after the war, where he was secluded in the deep depression that seemed endless. His luck changed when he bought a local bankrupt retirement home, "The Rusty Krab", which he decided to turn into a restaurant, adding a K to "Rusty", thus making it the Krusty Krab after his pirate ship. He decided to go into business, selling his family's Krabby Patty burgers. The Krusty Krab was extremely successful from the beginning, and has for years stood as Bikini Bottom's premiere daytime eatery.

At some point of his life, he was the head chef of the S.S. Diarrhea and cleaned the bathrooms on the S.S. Gourmet. Krabs's arch business rival is his one-time friend Plankton, who owns a restaurant called the Chum Bucket literally right across the street from the Krusty Krab. Plankton, a mad scientist and a technological and scientific genius, constantly attempts to steal the Krabby Patty Secret Formula, frequently using his various robots and other creations.

Occasionally, Plankton uses other tactics besides stealing the formula in order to hinder Krabs and attract customers to him. However, all of Plankton's schemes are doomed to fail, and are constantly thwarted by Krabs, with help from SpongeBob, Patrick, and other allies. On multiple occasions, Plankton states that he has never had a single customer (however, in some recent episodes, such as "Chum Caverns", Plankton's plots do give him brief success).

In The SpongeBob SquarePants Movie, Mr. Krabs opens The Krusty Krab 2, right next door to the original Krusty Krab. He chooses Squidward to manage the restaurant, much to SpongeBob's dismay. However, at the end of the movie, (after SpongeBob saves Bikini Bottom and Krabs's life), he is appointed new manager of the Krusty Krab 2. In "Squilliam Returns", Krabs works as the chef in Squidward's fancy new version of the Krusty Krab, but is apparently a terrible cook, creating a disgusting and freakish "appetizer", which eventually comes to life and begins attacking the restaurant's patrons. Even though he weighs 5 ounces, in one of the episodes he says he only put on a couple of pounds.

Before he established the restaurant, he tried to open a business along with his former best friend, Plankton. Their first customer was Old Man Jenkins, which their burger poisoned. Plankton and Krabs blamed each other and fought over the recipe, resulting with ingredients dropped into the meat, which became the Krabby Patty. At the end, Plankton only got one ingredient: Chum.

Krabs was a Navy cadet for some time and retired to running a business again. He bought a retirement home named the Rusty Krab and made it a restaurant. Currently, he has two employees: one loyal and hardworking and the other who does not care about his job and sleeps during his shifts. Occasionally, he would have extra employees to boost his success often being better without them in the end. Less often, he works for someone else or had another business.

In some episodes such as "Culture Shock" and "Squirrel Jokes", he provided entertainment to the customers. Other businesses that he owned include the Pretty Patties restaurant and the Kuddly Krab, which were not successful in the end. In The Krabby Kronicle, he was the editor-in-chief of the newspaper that he used to advertise the Krusty Krab. During Squilliam Returns, he served as the chef for the "five star restaurant" that Squidward "owned". He looked for a job when he was looking for something to do which led him to become the dishwasher in "Selling Out".

Some restaurants or businesses that he owned were a reformed version of the original Krusty Krab, a separate store, or a different idea. Some changes of the Krusty Krab turned the restaurant into others like the Kuddly Krab, 5 Star Krusty Krab, Krabby O'Monday's and The Krusty Sponge. Separate restaurants include the Pretty Patties Store and Krusty Krab 2. New ideas were made such as hotels like Krusty Towers Hotel.

Antagonistic Side
Mr. Krabs has an extremely prevalent antagonistic side and plays a recurring villainous role in the series.

The underlined episodes are where Mr. Krabs serves as the main antagonist of that episode.

Season 1

 * Pizza Delivery: He antagonized Squidward by making him deliver the Krusty Krab Pizza with SpongeBob. This marks the first time Mr. Krabs acted antagonistic. This is also a labor law violation because it was closing time before the pizza order even began.
 * Squeaky Boots: He took SpongeBob's boots away from him, because of the squeaky noise. The squeaky noise hallucination forced him to tell the truth (similar to the Narrator of "The Tell-Tale Heart"), eating them, and at the end of the episode, he got hiccups sounding exactly like the squeaky noise of the boots.
 * Scaredy Pants: He pranked SpongeBob with a ghost story with aid from Squidward just for amusement. This shows that Mr. Krabs is also a sadistic bully.
 *  Arrgh! : This is the first episode where Krabs is entirely the main antagonist of an episode. His first notorious deed was he hired Patrick just so he can fire him. Then, he kept harassing SpongeBob and intruded his pineapple house just to keep playing the board game, as while SpongeBob is exhausted and wants to go to sleep. The next morning, Mr. Krabs gets SpongeBob and Patrick to be pirates and help him find the Flying Dutchman's treasure. He becomes a tyrannical control freak towards the two, condemning them that they're tired and hungry from the treasure hunt, then makes them sleep on the cold ground while he himself gets a warm tent. The two eventually see that Mr. Krabs was using their gameboard as a map and that he wanted the treasure for himself. SpongeBob and Patrick then finally get fed up with Krabs's greed and fight over the treasure chest, then when the Flying Dutchman gets angered at how loud their arguing is and that they dug up his treasure, Krabs immediately incriminates SpongeBob and Patrick. In a twist of irony, the Dutchman rewards the latter two with actual gold doubloons and only gives plastic to Krabs.
 * Hooky: Humiliated SpongeBob in front of his daughter Pearl and her friends by stripping him naked.
 * Neptune's Spatula: After telling SpongeBob he has full confidence that SpongeBob will win the fry cook challenge, Mr. Krabs bets all his money on Neptune winning. However, SpongeBob was declared the winner and Mr. Krabs started crying. SpongeBob, thinking Krabs is crying since the former is being forced by Neptune to move to Atlantis to be a fry cook, tries to assure Krabs he'll come visit now and then, but Mr. Krabs complains he's crying about losing all his money.

Season 2

 * Bubble Buddy: Makes Squidward cater to Bubble Buddy, threatening to make his life miserable otherwise. Later he joins Squidward and everyone else in popping Bubble Buddy because SpongeBob had paid Krabs in (worthless) bubble-money for expensive services and food until they found out he was alive.
 *  Patty Hype : Takes over SpongeBob's Pretty Patties stand so he can earn money (even though he and Squidward laughed at Spongebob earlier about the pretty patties). However, the Pretty Patties turned out to have side effects that angered the customers. After pointing out the Patties added unnatural color to their appearances and demanding refunds, Mr. Krabs then ran away screaming in fear (because he's worried he'll lose his money, not because the crowd is angry at him). The angry mob of color-mutated fish may have caught up on Mr. Krabs and physically beat him up.
 * Life of Crime: Steals various objects from people and lies to SpongeBob and Patrick about borrowing. The lesson he taught them caused them to fight after a candy bar incident and the lollipop incident (Patrick also accused the policemen).
 * Pressure: Joined Squidward, Spongebob & Patrick into mocking Sandy just to prove that Sea Creatures are more superior.
 *  The Smoking Peanut : Mr. Krabs steals Clamu's pearl and abuses Free Day. SpongeBob believed he was the one who did it, but it was Patrick who became the scapegoat and people threw peanuts at him as revenge. The zookeeper explains Mr. Krabs angered Clamu by stealing her egg (containing a baby clam). Mr. Krabs doesn't apologize, only making up the excuse "But it's Free Day!" and the fish all throw peanuts at him. Off-screen, Mr. Krabs presumably was arrested by the police for petty theft.
 * Graveyard Shift: Made his employees work 24 hours without a break or hiring extra employees for the night shift (much to Squidward's dismay).
 * Sailor Mouth: He used foul language along with SpongeBob and Patrick after explaining to them about swearing and was about to punish them by making them paint the restaurant. This only began however when he stubbed his foot and lost his temper from the pain.
 *  Jellyfish Hunter : Tricks SpongeBob into collecting jellyfish. SpongeBob soon discovers that Mr. Krabs is squeezing jelly out of them so more Jelly Krabby Patties can be made (this even kills off lots of jellyfish up to where the factory resorted to using barrels to store their dead bodies). The jellyfish are set free and sting Mr. Krabs all at once, burning and electrocuting his body. He has no choice but to take jelly off the menu. This is the episode where Moar Krabs appears.
 *  Squid on Strike : Forcefully charges his employees for their "slacking", even though the stuff they did on the slacking list were needed to do their jobs (such as existing, talking, standing) and fired both of them. After Spongebob destroyed the Krusty Krab in revenge, Mr. Krabs forces him and Squidward to pay for the damages by working for him "FOREVER". The next scene cuts to SpongeBob and Squidward still working even after they've been reduced to skeletons.

Season 3

 * My Pretty Seahorse: Mr. Krabs tried to get rid of Mystery (in which SpongeBob tries to hide her from him and Squidward). He told SpongeBob about a story about losing a friend (actually a dollar he spent on soda) which inspired SpongeBob to release Mystery into the wild. It should be noted that Mr. Krabs wished for Mystery to be given up as he noticed she was not enjoying her unnatural surroundings and did console Spongebob when he tearfully gave up Mystery stating he had done the right thing for her. After Mystery does gallop away, Mr. Krabs tries to comfort SpongeBob who is lamenting her (as Krabs is in a good mood about having gotten rid of Mystery), Squidward teases that Mystery managed to eat the Krusty Krabs's cash reserves and therefore Krabs yells at SpongeBob to quickly get her back. The audience can imply that SpongeBob and Mr. Krabs never found Mystery since she didn't make another appearance and so Mr. Krabs never recovered the money she ate.
 *  Nasty Patty : Forces SpongeBob to help him make a Nasty Patty, because he thought the health inspector in his restaurant was a phony. He along with SpongeBob try to get rid of the "body" which was still alive, getting the health inspector injured more and more.
 * The Sponge Who Could Fly (Lost Episode): Mr. Krabs along with everyone else in Bikini Bottom took advantage of SpongeBob and his flying pants by making him do their favors.
 *  One Krabs's Trash : Mr. Krabs tries to take back a soda-drinking hat he sold to SpongeBob after hearing about its price. He scares SpongeBob out of it with a paper ghost and defiles a grave to get it back, only to find out it was worthless. He also kills an army of skeloton people who just wanted the hat back.
 *  Can You Spare A Dime?  : Accuses Squidward for stealing his first dime, until SpongeBob shakes him. He then accuses Squidward for putting the dime in his pants at the end of the episode.
 *  Wet Painters : Messes with SpongeBob and Patrick by scaring them into thinking the paint they were using was permanent and tells them if any paint got onto anything but wall, he would chop their butts off. After they get some on his first dollar, he licks it off and confesses his lie and that it comes off with saliva and laughs while the two walk out angrily. He ruins Spongebob and Patrick's work by laughing about his own joke, causing saliva to hit the walls. It was noted that his first dollar came from his childhood.
 *  Clams : He throws away the food, made SpongeBob and Squidward stay in the fishing boat, and holds them hostage to get back his millionth dollar from a giant clam. It gets worse when he refuses to take another dollar Squidward had. He gets his dollar back after trading his body with the clam.
 *  Born Again Krabs : Tries to sell a rotten Krabby Patty to customers. He gets sick after eating it and is persuaded to be generous by the Flying Dutchman. However - after realizing it wasn't a dream - he steals back toys from children, soda from a customer, stopped another customer from watching free TV, nearly rips someone's arm off for a penny, and trades SpongeBob's soul for 62 cents. Squidward was the one who was horrified that Mr. Krabs would sell SpongeBob's soul, especially when SpongeBob defended Krabs.
 *  Krabby Land : Creates a bogus theme park and masquerades as a clown so he can collect children's money. This brings SpongeBob to tears, and the children beat Mr. Krabs up and take his money after finding out he didn't care one bit about them, only their money. As punishment for his scam, Mr. Krabs gets forced to eat a truckload of lima beans.

Season 4
This is the first season not to have Krabs as the main antagonist of ANY EPISODE IN THE SEASON.
 * Fear of a Krabby Patty: Makes the Krusty Krab open for 24 hours, making Squidward upset, and SpongeBob fearing Krabby Patties (although he conquered his fear by sleep). He then decides that 23 hours a day is enough.
 * This is the second time he kept the restaurant open for 24 hours; the first time was in Graveyard Shift. However, unlike in aforementioned episode, he stays at the Krusty Krab with his employees, thus suffering from the same lack of sleep that they do.
 * Krusty Towers: Plagiarises the law of the hotel he visited into the Krusty Towers making Squidward miserable. Squidward quit and returned as a customer ragging Mr. Krabs the same way he did with him. At the end of the episode, he decides to build a hospital and force his employees to become doctors making Squidward miserable again.
 * Bummer Vacation: Keeps SpongeBob away from the Krusty Krab to avoid paying a fine, eventually leaving him lost in the forest. Doing so, he managed to save five cents - more than what SpongeBob makes in a year.
 * Born To Be Wild: Invites the Mild Ones to the Krusty Krab much to SpongeBob's chagrin. Counts as an antagonism because SpongeBob still mistook the Mild Ones as the Wild Ones.

Season 5

 *  Money Talks : Does not listen to his money when they want to be spent on objects. He also kicks an elderly couple out of their seat after being bribed by a fish who wanted the seat. This episode also shows that he has sold his soul to many demons, depressing the Flying Dutchman. He also sold his soul to SpongeBob because he was five cents short on payday.

 * Growth Spout: He steals numerous food items from characters' houses. Though he only does so to satisfy Pearl's extreme hunger.
 * Plankton's Regular : Grows jealous of Plankton having a regular customer (even though he gets way more), and tries to steal his secret recipe. It was later revealed that the "customer" was only eating at the Chum Bucket to get paid, and Plankton started crying over his failure once again while Mr. Krabs watched with joy.
 *  Krabby Kronicle : Creates a newspaper and makes SpongeBob write lies about people, ruining their lives. SpongeBob tries to stop but Mr. Krabs threatens to take away his spatula.

Eventually, he made Patrick fall into a bucket of spiny sea urchins and while Squidward was falling, he charged the customers more money to watch them both get hurt. People took their money back, because only Squidward was hurt and not Patrick. Also, he made Patrick cry by firing him and taking his Krusty Krab hat away.

Season 7

 * Greasy Buffoons: He and Plankton sell customers greasy food (mostly just grease period). This eventually turns people (including Patrick) into overweight, mindless zombies.

 * Kracked Krabs: Mr. Krabs charged everyone $1 per footstep as shown in a video tape.
 *  One Coarse Meal : On discovering Plankton's crippling fear of whales, Mr. Krabs dresses up as Pearl and terrorizes Plankton for 17 days.

 * The Play's The Thing: Mr. Krabs made money by letting customers throw objects and food at his employees.
 *  The Cent of Money : Mr. Krabs uses Gary as a coin magnet.

 *  Barnacle Face : Decides not to help Pearl with her barnacle problem. It was soon revealed that he used krabby patty grease to make the soap used by Pearl, thus revealing the cause for the barnacle problem. He loses his diamonds because of this and tries to run after Pearl for his diamonds.

Then after seeing Spongebob crying out the right amount of mustard, he starts saying it's a terrible thing just to make him cry more.

 * What's Eating Patrick?: Teaches Patrick how to eat in order to win the eating contest, even in means of depriving him from tasting the patties. During the contest, Patrick tries to leave because he was tired of not tasting, only for Krabs to tell him if he does, he bills him, stating that all the training patties become eating patties. While Krabs's threat to Patrick held some morality (such as how the boy and the rest of the town would be upset if they lost the contest yet again), his methods were still harsh to Patrick's esteem of eating.
 * The Sewers of Bikini Bottom: He, along with Crupski, showed no concern about the customers' safety at the stadium and cared less about the consequences when the plumbing system begins to go haywire.
 * Larry's Gym: After overhearing Larry about that the opening of the gym is free only for today, Mr. Krabs takes advantage of the opportunity and stays there thoroughly.

The SpongeBob Movie: Sponge Out of Water
In this sequel to The SpongeBob SquarePants Movie, Mr. Krabs has commited several heinous acts, making himself different from his more innocent self in the previous movie. Examples are down below:
 * Mr. Krabs and numerous Krusty Krab customers constantly tease Plankton, who is actually a robotic decoy of him, thinking that he's suffered from another failure to steal the Krabby Patty secret formula.
 * After SpongeBob and Plankton discover that the secret formula surprisingly disappeared, Mr. Krabs shows up and accuses Plankton of stealing it, even though Plankton truthfully said that he didn't do it. Mr. Krabs wouldn't listen, even when SpongeBob was defending him that he's telling the truth, and traps Plankton in tape and tells a knock-knock joke to make Spongebob do his signature laughter and torture Plankton forcing him to tell where the secret formula is. Then, while Mr. Krabs and the Bikini Bottom citizens attempt to attack him, SpongeBob rescues him with a giant bubble. Mr. Krabs instantly thinks that Spongebob has been a double agent working for him and Plankton all these years as they both float away.
 * Mr. Krabs then becomes a leader of a savage group of apocalyptic sufferers. Then, while they were planning a sacrifice for the burger gods, which a savage Sandy explained, Spongebob and Plankton return from time traveling. Then, even when Spongebob tried to convince the people how savage they've become with the formula missing, Mr. Krabs and the rest attempt to sacrifice Spongebob by having him get squashed by a falling burger-bun-shaped stone. Spongebob smelled the familiar scent of Krabby Patties coming from the outside surface, which is coming from Burger-Beard who's the one that really stole the formula. Then, as the stone is about to fall on Spongebob, Mr. Krabs stops it after he and the others smell the scent as well, as they aid Spongebob to follow the scent.
 * Mr. Krabs notices that Burger-Beard is selling his Krabby Patties for $8.99 and says to himself, "Why didn't I think of that?"
 * During the end credits, he pulls Patrick's wallet out of his pocket.

Battle For Bikini Bottom

 * He has a large posession of Golden Spatulas which he knows are needed for Bikini Bottom to be saved, but refuses to let Spongebob have them unless he trades them for a large quantity of shiny objects.
 * When Spongebob reluctantly disagrees to give him a hard earned Golden Spatula, Mr. Krabs makes Spongebob's break time at work -5 minutes, effectively meaning he has no break and has to work an extra 5 minutes.
 * After having bought all the Golden Spatulas Mr. Krabs has, the player can still talk with him. However he only ever says the one thing; "The only good robot is the one that's givin' me them shiny objects". This is a subtle reference to the possibility that Mr. Krabs thinks of Spongebob as a robot which is actually another word for slave.
