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.
