Eugene H. Krabs, usually called Mr. Krabs, is one of the main characters of SpongeBob SquarePants. He is the penny-pinching owner and founder of the Krusty Krab restaurant. While he can come across as incredibly selfish, he is a caring and thoughtful crab deep down. Mr. Krabs dotes on his daughter Pearl and appreciates his employees, SpongeBob and Squidward.
Mr. Krabs sometimes identifies himself as a sailor and served in the Navy at one point (earning the nickname "Armor Abs Krabs"). During his service, he was the chief janitor on the S.S. Gourmet and "head chef" on the "S.S. Diarrhea" (figure of speech, since he cleaned the bathrooms). Sometimes when he appears onscreen, sailor's music is played; Krabs uses sea-faring vocabulary; he calls disagreement mutiny and calls the bathroom the head while his laugh is akin to those of sailors. Krabs is something of a miser; he is known to go insane if he has to give up so much as a penny. He is reluctant to purchase just about anything, even though he's the richest crab in the ocean. Pearl is often extremely disappointed in Mr. Krabs' gifts to her, such as on her 16th birthday or the infamous squeaky boots.
He's an important background character in The SpongeBob SquarePants Movie, one of the two main antagonists (alongside Burger-Beard) turned antihero in The SpongeBob Movie: Sponge Out of Water and the tretagonist in The SpongeBob Movie: Sponge on the Run.
Ever since he was a young child, Eugene H. Krabs has always been a penny-pinching financial genius, like he is in the present day. In the episode "My Pretty Seahorse", Mr. Krabs told SpongeBob of a story about his father giving him a dollar at the age of five years old. He recalls that he loved that dollar like a brother; however, he spent it on a soda, one hot day at the beach.
After the war, Krabs stay secluded in a deep depression that seemed endless. His luck changed when he bought a local retirement home, "The Rusty Crab," which he decided to turn into a restaurant, adding a K to "Rusty" and replacing the C with a K ("Krab"). He decided to go into business selling his family's Krabby Patty burger. It was revealed to be a family secret in "Enemy In-Law", and it was King Krabs who named the burger, back in the Middle Ages. In 1959, a chum famine wiped out all of the chum crops, causing Krabs to give breaks to his employees.
Mr. Krabs served in the navy, at an unknown age. He worked as the janitor on the S.S. Gourmet and the head chef of the S.S. Diarrhea.
The Krusty Krab has come close to going out of business due to such rival restaurants as the aforementioned Chum Bucket, Pretty Patties, and The Shell Shack just to name a few. The building is also in serious disrepair, as its walls ooze green slime, and it has seriously faulty electrical wiring. Mr. Krabs idea of maintenance is to simply place bandages on cracks in the walls, which obviously is inadequate.
An Olympics-type sporting event was started about 1981, the Fry Cook Games. Krabs competed against his arch rival, Sheldon J. Plankton. Mr. Krabs won gold for a challenge by lifting a pickles-dumbell, however lost to Plankton in the Onion-Ring Routine.
In The SpongeBob SquarePants Movie, Krabs opened The Krusty Krab 2, right next door to the original burger stand, where Squidward is chosen to be the manager (much to SpongeBob's dismay).
He is a descendant of the Krabs family of prehistoric times who constantly repeat the word "Money".
