Sheldon Plankton is Eugene Krabs's arch enemy. He often goes by just Plankton. He wants to steal the Krabby Patty Secret Formula, so that his restaurant, the Chum Bucket becomes famous and the Krusty Krab goes down. But in the episode Friend or Foe? we come to know that Mr. Krabs and Plankton best friends were and because of the formula they became enemies!

Sheldon and Eugene were in the same kindergarten and same School and also were in a university.
He lives with his computer W.I.F.E Karen Plankton and a Labrador in his own restaurant. Sheldon stole Karen from a hospital (Friend or Foe?)
According to his analyzer, Sheldon is made up of 1% evil and 99% hot gas. In Friend or Foe?, despite Karen's truth, Plankton really does want the Krabby Patty formula for ruling the world but also Mr. Krabs wants the Krabby Patty formula for making lots and lots of money.

Personality

Sheldon is very jealous, but he is sneaky and nearly arrives to steal the mysterious Krabby Patty Formula. He never arrives it because he is too overhasty and impatient, he cannot wait. He thinks he can outgun everyone and doesn't want to believe that he is small.
Before he was Mr. Krabs's enemy, he was his only friend! Everyone else laughed at him because he is so small and easy to beat him, but because Mr. Krabs was with him he wasn't too angry. But since they are enemies he wants to govern the world and revenge everyone who laugh or laughed at him.
He often rips SpongeBob off, because he thinks SpongeBob is silly and babyish'; also because SpongeBob happens to know the Krabby Patty's ingredients. (He puts upon SpongeBob in episodes like Walking Small or Plankton!.) Plankton is the main antagonist and main villain of the SpongeBob SquarePants TV series. He is also SpongeBob's arch nemesis.

Looks

Plankton is small and jelly bean shaped. He has one eye that has a red pupil. He has long antennae. His arms are stubby, and he's a dark green color.

Plans

Main article: List of Plankton's Plans

Major Plans

• In the episode "Plankton!" he uses a mind control device on SpongeBob, but SpongeBob resists a bit and because of SpongeBob's inviting description of the Krabby Patty, Plankton lunges for a Krabby Patty and falls into his analyzer. Plankton becomes trapped inside Karen, and tells SpongeBob that he'll settle for some fries.

• In "F.U.N." SpongeBob teaches Plankton to have "F.U.N." and they become friends. Nevertheless, Plankton rips SpongeBob off, so that he gets the formula. But he slams into solid concrete behind a movie theater screen.

• In "Imitation Krabs" Plankton arrives to get rid of Krabs for a while, so that he can clad him as Mr. Krabs, but Mr. Krabs returns to the Krusty Krab. SpongeBob is unable to figure out who is the real Mr. Krabs so he does a quiz show.Plankton won the quiz show so SpongeBob gave Plankton the formula. SpongeBob finds a penny and puts it in the Krabs robot's self destruct slot, so Plankton goes to the Chum Bucket and got blown up.

• In "Plankton's Army" Plankton fails to get the formula, so he decides to call in for help (actually Karen's idea). He tries a Bar, but he gets injured by the men, so he calls in his family. He hopes and assumes that they're evil geniuses like him, but turn out to be dumb and clumsy. They say they'll help if they get rewarded with "Root Beer". They invade the Krusty Krab and trap Mr. Krabs and Squidward in a toilet (SpongeBob was mopping the Bathroom). Plankton's family figures out the code for Mr. Krabs's safe, Plankton gets the book of the recipe even though Mr. Krabs asked him not to, but the Formula says that Grounded Plankton are part of the recipe. Plankton and his family retreats when Mr. Krabs made it sound like he was going to use Plankton as Part of the recipe. Mr. Krabs tell SpongeBob and Squidward that the book wasn't the real formula, and that he's sure that Plankton will be back someday to discover what the real Formula is.

• In "Welcome to the Chum Bucket" Mr. Krabs loses SpongeBob in a card-game against Plankton. Now SpongeBob must work in the Chum Bucket. Of course he wants SpongeBob to prepare a Krabby Patty but SpongeBob does not do it. Therefore, Plankton implants SpongeBob's brain in a robot, but it does not make the Krabby Patty either. Plankton returns SpongeBob's brain and is desperate to offload him on Mr. Krabs. So desperate in fact, that he gives Mr. Krabs $50.00.

• In "Krusty Krab Training Video" Plankton steals a Krabby Patty and goes away with a vehicle which looks like an insect, but it is so slow that Mr. Krabs can stop it. "I knew I should have gotten the turbo".

• In "Fear of a Krabby Patty" Plankton learns that the Krusty Krab is open 24 hours. Pretending to a be a customer, Peter Lankton, Plankton orders 10,000 Krabby Patties. After many days of working without sleep or rest, SpongeBob starts hallucinating, and becomes fearful of Krabby Patties. SpongeBob goes to a psychiatrist who is Plankton with false name. Plankton tries to get the formula by hypnosis, but SpongeBob falls asleep in the process, thereby curing him. SpongeBob can begin to work again and Plankton has not gotten the formula.

• In "Friend or Foe?" Plankton tells Mr. Krabs he has wanted to steal the formula so that they will become friends. During a heartfelt hug, Plankton notices the formula is in Mr. Krabs’s trouser pocket and he takes it. Plankton and Karen want to disappear and SpongeBob and Mr. Krabs want to hold them up.

• In the "The SpongeBob SquarePants Movie Plankton learns there are 26 letters in the alphabet and executes "Evil Plan Z", where he steals the crown of King Neptune, delivers it to Shell City (a gift shop located on the surface), and frames the theft on Mr. Krabs, whom Neptune freezes and gives six days for his name to be cleared before his execution. While Krabs is frozen, Plankton successfully steals the Krabby Patty formula and begins producing Krabby Patties, giving free bucket helmets away with each one. The helmets are, in fact, mind-control devices which Plankton uses to make the citizens bend to his will and change Bikini Bottom to suit his image, renaming the city "Planktopolis." Unfortunately for Plankton, SpongeBob and Patrick manage to retrieve the crown and bring it back to King Neptune, and frees the townspeople from Plankton's control by using the power of rock and roll. Plankton is trampled before he can escape and a while later, the cops take him to prison for illegal mind-controlling.

• In Komputer Overload, Plankton builds 3 robots: the T-119A Compumatic, the Noxious Enterprises' Super SPU-31 Liquid-Cooled Mobile Processing Unit, and the Command Module to replace Karen, who had left. He then puts the 3 robots together, making one big robot to get the secret formula. He threatens to SpongeBob, who had been thrown outside by Mr. Krabs, to "tell Krabs that if he doesn't turn over the formula to me, he'll be subjected to utter annihilation at my hands", but SpongeBob doesn't get that, so he puts it simply: "Krabs give me secret formula or I bring big boom boom to the Krusty Krab." SpongeBob doesn't understand that, either. So Plankton attacks the Krusty Krab, declaring "Bring on the boom boom!" However, the extension cord used to power the robot unplugged, making it stop working. SpongeBob and Mr. Krabs laugh at Plankton's expense as the robot collapses. Karen comes back to Plankton, but only to get her keyboard. Plankton apologizes and goes back to the Chum Bucket with Karen.

• In Someone's in the Kitchen with Sandy, Plankton got trapped in Sandy's air suit and after watching her sloppily eat a Krabby Patty. He later stole her pelt, but then Sandy stopped him and imprisoned him in a jar of mustard.
• In Atlantis SquarePantis Plankton plans to use Atlantis's powerful weapons on the Gang to become Emperor of the city. He was stupid enough to find out that the weapons shoot Ice Cream. "Ice Cream? It shoots ICE CREAM!!!" His song was So Many Weapons.

• In The SpongeBob SquarePants Movie Karen warns Plankton that if SpongeBob and Patrick make it back to Bikini Bottom with the Crown (Plankton stole King Neptune's crown and frames Mr. Krabs) Neptune will discover Plankton's "Fingerprints" on the crown. Plankton reveals that he sent Dennis (The Hitman) to destroy the heroes. But Dennis dies when he hits a boat and breaks his head off on Hassoleholf.

• In Bucket Sweet Bucket, Plankton tricks, SpongeBob, Patrick, and Squidward to fix up the Chum Bucket. He goes to the Krusty Krab where he tries to get the formula. He succeeds, but it says "One Bottle of Molting lotion" "Take Passport Photo" "Get new safe (Travel size)". He rips it up finding out it's a "To Do List". He goes back to the Chum Bucket where he discovers that SpongeBob and Patrick (Squidward quit) turned the Chum Bucket into the Krusty Krab. Mr. Krabs comes back from his Vacation to Africa, and he reveals that he took the formula with him on vacation. He then takes back the Krusty Krab afterwords. Karen scolds, "Oh Excellent Job Genius! You really fixed the place up!"

• In Truth or Square, Plankton tries to steal the formula while SpongeBob, Patrick, Squidward, and Mr. Krabs are in the freezer. But, later he is caught by Mr. Krabs.

Minor Plans

• In 1979, Plankton asked nicely to Mr. Krabs Can I please have the secret formula? and Krabs refuses.

• In Plankton!, he gets under the Krabby Patty and tries to get out of the Krusty Krab.

• In Imitation Krabs, he goes under a fish-robot and asks SpongeBob the formula to win $1,000,000.00 (the dollar was fake)

• In Sleepy Time, he was giant and rampaged across Bikini Bottom, and his final target was Gary. Somehow SpongeBob turned into a nail, so that when Plankton stomped on him, he got a hole in his foot and shrunk.

• In "Culture Shock" Plankton tries to steal a Krabby Patty by conjuring, but he exposes himself with his magic.

• In the video game Battle for Bikini Bottom Plankton builds a machine that he uses to create an army of loyal robots, but he forgets to set a switch on the machine to Obey Plankton, and also even makes a robot clone of himself, which results in the end of his plan.

Trivia

• He never wins. When he thinks that nothing can come between him and the formula, he gets ahead of himself and eventually does not obtain it.

• He was in love with Mama Krabs in Enemy In-Law.
• In the episode Krabby Road, he was kicked out by Karen.

• Plankton seems to change size in every episode he appears in (his 5 in. measuring stick say he's 2 in. tall in "Komputer Overload").
• His analyzer is wrong because Plankton is really evil as seen in the movie when he takes over Bikini Bottom and steals the formula. Plus, in some episodes he uses SpongeBob and friends in his plans to take the formula.
