Sheldon J. Plankton, mostly known by his surname Plankton, is a fictional character and one-eyed typical cartoon villain in the animated series SpongeBob SquarePants. He is a technologically savvy, deep-voiced zooplankton with one central eye—a real-life characteristic of some copepods. Plankton is the smallest of the main characters in the series, able to fit in SpongeBob SquarePants' hand, as well as under Mr. Krabs' foot, as he is only slightly larger than a jelly bean (In fact, he was once mistaken for one in the episode F.U.N.). His size has actually differed from the earlier episodes to the later ones. In the latter he was depicted as bigger. His appearance is nowhere in the Halloween episode "Scaredy Pants".

General

Plankton is a plankter and runs a "competing" (though remarkably unpopular) restaurant called the Chum Bucket, which is located directly across the street from the Krusty Krab. Despite its proximity to the Krusty Krab, the Chum Bucket itself is rarely seen in the cartoon, except for those episodes in which Plankton also appears. Plankton lives at the Chum Bucket with Karen, his dear computer "WIFE" (Wired Integrated Female Electroencephalograph), who irritates him to no end. Plankton's first name, Sheldon, is constantly made fun of by his computer wife. He acts as Mr. Krab's arch enemy, and is SpongeBob SquarePants' occasional nemesis, though many times SpongeBob is naive of Plankton's evil powers. Plankton is a science wiz, and even knows how to induce thermonuclear fusion. His primary catch phrase is " You can't do this to me, Krabs! I went to college!!!", which he usually says while flying back towards the Chum Bucket after one of his schemes to steal the Krabby Patty secret formula has been thwarted, though it has been used in other context.

His desire is to infiltrate the Krusty Krab and put Mr. Krabs out of business. All of his nearly successful but ultimately foiled plans involve getting hold of the secret recipe for the copyrighted Krabby Patty, the main food item served at the Krusty Krab, in order to get customers. Plankton frequently plays on the naive trusting nature of SpongeBob to try and get the recipe, along with engaging in various forms of trickery or theft to get either a Krabby Patty or the recipe. These forms have ranged from posing as a psychiatrist for SpongeBob to using a self-controlled robot version of Mr. Krabs. Plankton is almost always scheming away in his laboratory. In The Spongebob Squarepants Movie, Plankton used buckets to control the citizens of Bikini bottom, though lost to the combination of Goofy Goober-ness and rock n'roll.

Plankton's best friend from birth was his future rival Eugene Krabs. Both Krabs and Plankton were considered outcasts by other children, because Krabs was poor and Plankton was a nerd. When they discovered money could bring them out of their poverty, they decided to make money selling hamburger patties. At first, their burgers were mildly successful, but the kids ended up throwing them up. They set up shop in the dump to sell the patties. No one would come to the dump, so they gave one to Old Man Jenkins, who had helped the Krabs family. The bad patty killed Jenkins. Strangly, He has appeared in other episodes. It could be that there are two old fish with this name, or that it is just a goof. Plankton was dared to improve upon the recipe, but only ended up with the shard of the recipe which read "and a pinch of chum". Plankton stormed out of restaurant, and went to create his own recipe using chum, memory, and science. At school, Plankton attempted to sell his chum burgers in a chum bucket and failed, whereas Krabs succeeded with his Krabby Patties, which he had created by accident when Plankton had slammed the door. Ingredients fell in the patty batter, thus creating the patty. Plankton later named his restaurant the Chum Bucket, after the secret ingredient of the original failed patty recipe.

Family

Plankton has various relatives, whom he enlists help from in "Plankton's Army" while attempting to retrieve the Krabby Patty secret formula. Relatives include (but are not limited to): Clem, Zeke, Rufus, Jete, Billy Bob, Billy Jim, Billy Billy Bo Willy Banana Fana Fo Filly, Doug, Toad, Enis, Rainchild, and Fletcher McGee. His relatives appear to be a big bunch of friendly, gullible, multicolored, root-beer crazed, uneducated hillbilly plankton, whom Plankton himself barely even recognizes. Unlike his relatives, Plankton got his ingenious mind from going to college. The episode Dunces and Dragons implies that the Plankton-Krabbs feud began centuries before when Plankton's ancestor the evil wizard "Lord Planktonomor" held the medieval kingdom of "King Krabs" -until "Spongebob" and "Patrick" literally dropped in and changed history-with the first "Krabby Patty."
