The story and appearances of Plankton from SpongeBob SquarePants.
Past[]
Sheldon J. Plankton was born on November 30, 1942 somewhere in Bikini Bottom. Before the events of the series, Plankton was also coincidentally born on the same day as Mr. Krabs, whereafter both the two would soon meet each as babies and later best friends.
During his childhood with him, Both Plankton and Krabs were considered outcasts by their Classmates, most notably a school group led by Billy because Krabs was poor and Plankton was already very intelligent, which earned him the image of a nerd. When they discovered that money could bring them out of their poverty, they decided to make money selling hamburger patties and set up a mini-restaurant in the local dump.
Plankton vowing revenge on Krabs
At first, their burgers were not successful; the first of their patties were tried by Old Man Jenkins, who was knocked out by the contaminated burger. Plankton started complaining about how Jenkins had been old and not able to handle the patty. Offended by this, Krabs tried to take the recipe from Plankton to improve upon. Plankton wanted to do this himself and both he and Krabs argued, but he only ended up with the corner of the recipe, which read: "And a pinch of chum.". Now ending the frienship, Plankton stormed out of the restaurant and went to create his recipe, using only his memory, the corner of the recipe, and science. At school, Plankton tried to sell his chum burgers in a chum bucket and failed, while Krabs succeeded with his Krabby Patties, which he had created by accident when Plankton had forcefully slammed the door. Ingredients fell in the patty batter, thus creating the patty. Mr. Krabs named his restaurant the "Krusty Krab", after himself.
At some point after his newfound rivalry with Mr. Krabs, Plankton, still in his childhood age, had been living with his family at the hillbilly household, and none of the family members, especially his parents, are comparing to him as the smartest of the bunch, always dreaming about world domination. Some family members made fun of him because Plankton had no friends, even after his torn friendship with Mr. Krabs. So Plankton decided to make a new friend by plugging the calculator with a potato and petri dish, and his new friend was named Karen. Plankton and Karen spent time together over the years despite Plankton's family kept making fun of him. Now becoming a young adult, Plankton finally left his family home and head out to college with Karen.
Arriving at Bikini State University, Plankton realized there was no education about world domination and failed in every class due to him making ridiculous inventions. In order to stop failing, Plankton upgraded Karen with a new body on computer screen as well as the personality chips (smart, evil, snarky, and empathy) to have new emotions. With the fully-upgraded Karen's help, Plankton eventually passed college and headed out with Karen to take over the world together.
In their first attempt for world conquest, Plankton and Karen rode on a huge tank with a freeze ray to go up to the surface from the ocean, but their first evil plan went backfired as Plankton realized the humans are way bigger than the BSU students used to. A little human girl, thinking Plankton's tank is a toy, put Plankton and Karen in a bucket connected to a purple glove and threw them far away back into the ocean. Afterward, Karen took Plankton to the Krusty Krab to make him feel better, but Plankton said eating Krabby Patties would not solve anything to achieve world domination until Mr. Krabs jokingly explained to one of his customers that the Krabby Patties will "take over the world", inadvertently making Plankton change his new lifestyle.
He and Karen used the same huge bucket the little girl threw and built a new restaurant called the "Chum Bucket" in front of the Krusty Krab so Plankton can steal the Krabby Patty secret formula to have all of the Bikini Bottom eat in his restaurant and then take over the world. While cooking disgusting chum, Plankton proposed to Karen with a metal ring, and both eventually got married.
To this very day, Plankton has been single-mindedly obsessed with obtaining the Krabby Patty formula and running the Krusty Krab out of business over the years before SpongeBob first got his job. He often goes to incredible and quite ridiculous lengths to do so. In "SpongeBob's Last Stand," for example, he builds a massive highway that goes straight through Jellyfish Fields and over the Krusty Krab, leading right to his restaurant.
Series[]
Plankton constantly attempts to steal the formula for the Krabby Patty, the delicious burgers that are sold in the Krusty Krab. Plankton believes that the Krabby Patty is the reason for the Krusty Krabs' success and that his Chum Bucket would be equally popular if it sold the Patties as well. However, ensuring the success of his business is only the first step in Plankton's plan, which will culminate in him ruling the ocean.
For the post-movie events, Plankton does find alternate means to achieve success, but only temporarily. His schemes also vary regarding their threat level. Sometimes they are harmless; other times they put others including Plankton himself in danger.
Season 1[]
Plankton made his debut in "Plankton", when he was trying to steal the Krabby Patty Formula as the latter uses a plate to fling him back to the Chum Bucket. Mr. Krabs explains to SpongeBob that Plankton is his arch-competitor, and has been trying to steal the Krabby Patties secret formula for years.
Later at that night, after the Krusty Krab closes, Plankton tries to convince SpongeBob, that he and the fry cook are friends, and that SpongeBob should come to Plankton's birthday, as if it is supposedly the following day. Plankton says that friends give each other things. Plankton asks SpongeBob what he thinks he'd like for a birthday present, and SpongeBob then guesses a booster seat, as Plankton is very happy with that proposition, but then refuses. Plankton tells SpongeBob that, for his birthday, he wanted to give him a Krabby Patty. SpongeBob loudly and boldly refuses and runs back home, but Plankton promises that SpongeBob will "hand deliver it to (him) personally."
Later that night, Plankton enters SpongeBob's head through a pore and makes his way through SpongeBob's brain. He attaches a mind control device to the brain and bends SpongeBob down to his will, as he forces him into walking at the Krusty Krab by getting a Krabby Patty, and then bring it to the Chum Bucket's Laboratory. He brings it to an analyzer, which is designed to figure out the ingredients of whatever is dropped into it. As Plankton gloats over his victory and begins to force SpongeBob to drop the Krabby Patty, SpongeBob laments his failure as he lovingly describing the Krabby Patty's ingredients and succulence (which is ironically revealing the Secret Formula). A hungry Plankton then leaps out of SpongeBob's head and onto the Krabby Patty, but bounces out of it and falls into the analyzer, thus trapping him inside his computer screen as SpongeBob walks home with the Krabby Patty in hand.
Plankton appears in "Culture Shock", where he pretends to be "The Amazing Plankton" by using magic as he turns his wand into flowers and throws the flowers aside as he asks a volunteer from the audience as a customer gives him a Krabby Patty which Plankton then escapes to the door, only to be stopped by Mr. Krabs. Much to Plankton's dismay.
In "F.U.N.", Plankton, controlling the patty, escapes outside with it by making a hole in the door with a laser.
SpongeBob heroically chases after it. After a long chase, SpongeBob finally recovers the Krabby Patty and is congratulated by the townsfolk, while Plankton walks away sadly. SpongeBob, feeling sorry for Plankton, decides to befriend him.
SpongeBob invited Plankton to go jelly-fishing with him, realizing he can take advantage of SpongeBob, as Plankton goes. At Jellyfish Fields, Plankton remains fixated on evil and destruction, while SpongeBob tries to explain fun to him by singing "The F.U.N. song." Eventually, Plankton then started singing the song as well, first, he sings a corrupted version that displayed on horrible things but eventually, he sings SpongeBob's version and seems to finally be having fun. He seems to forget about stealing the formula and begins to develop a genuine sense of friendship.
Later at the cinema, SpongeBob reaches into Plankton's pocket and finds a Krabby Patty. SpongeBob realizes that Plankton used him to get a Krabby Patty, and Plankton attempts to explain that he realizes now that he only ever wanted friendship, before admitting to everything and running off with the patty through the movie screen, tearing it in half in the process.
SpongeBob believes Plankton won but Mr. Krabs tells him he did not. He shows SpongeBob behind the screen revealing Plankton to be badly squashed on a damaged concrete wall with the Patty. SpongeBob apologizes to Mr. Krabs and they decide to go back to the Krusty Krab and have a fresh Krabby Patty and Mr. Krabs flicks Plankton off the wall and onto Bubble Bass' hand where he mistakes Plankton for a jelly bean as Bubble Bass chases Plankton around his hand with him screaming.
In "Sleepy Time", Plankton's dream was revealed to be a giant causing destruction in Bikini Bottom, he then appeared at the end off the episode along with everyone in his house complaining that he's messed up their dreams and tells him to stay out.
In "Valentine's Day", SpongeBob gives Plankton a Valentines candy for Valentine's day.
In "Walking Small", Plankton (in his bulldozer) attempts turn the beach into the future site of the "Chum Bucket Mega Bucket," and demands everyone to leave. However, due to his tiny size and small voice nobody pays attention to him. He concludes that he needs someone big to assist him, and encounters SpongeBob. Plankton then decides to trick SpongeBob into being "assertive" in order to get what he wants. Plankton tricks SpongeBob into becoming assertive so he can build his Mega Bucket.
He tries to get SpongeBob to take his ice cream back from the person who stole it, but SpongeBob's kindly nature prevents him from being able to take it. Plankton, (unhappy with SpongeBob's performance), then climbs into SpongeBob's mouth and uses his words to forcefully take the ice cream. the guy who stole SpongeBob's ice cream runs off crying. When SpongeBob points about this, Plankton lies and says to him that those were the 'tears of joy', saying that the guy was happy that SpongeBob was assertive.
Plankton attempts to have SpongeBob forcefully take back his metal detector that he lent to another beach-goer, yet SpongeBob misinterprets Plankton's instructions and the person he lent the detector to is pointed out buried treasure by SpongeBob.
Plankton allows SpongeBob another chance. SpongeBob commits a series of both assertive and antagonistic acts to the beach-goers, such as stealing the hot dogs of people waiting in line to buy them and cutting the strings of people's kites, and even worse, popping a volleyball that the beach-goers wanted to play with, resulting in everyone leaving the beach.
Plankton then reveals his true intentions to SpongeBob, making him very upset. SpongeBob then becomes becoming "aggressively nice," and he undoes the actions that led everyone to leave Goo Lagoon. Plankton leaves the beach due to the overwhelmingly generous acts of kindness that SpongeBob executed.
Season 2[]
In "Imitation Krabs", Plankton, (in his newest bid for the Krabby Patty secret formula) enters the Krusty Krab as a robotic salesman and presents SpongeBob with an offer for one million dollars if he tells him the formula. SpongeBob explains, but in no uncertain terms, that the formula is the property of Mr. Krabs and may not be divulged. Enraged, Plankton bursts out of the robot and threatens SpongeBob with violence, only to be caught by Mr. Krabs and shot out from a straw back to the Chum Bucket. Later, he poses as Mr. Krabs using a robotic duplicate to trick SpongeBob into giving him the formula and distracts the real Mr. Krabs using a penny. Somehow, SpongeBob falls for it and nearly gives him the formula until the real Krabs comes back. Unable to tell which is the real Mr. Krabs, SpongeBob threatens them with tartar sauce and asks them several questions. Plankton correctly answers the first two, but the third question is nearly impossible to answer, causing SpongeBob to think the real Krabs is the imposter and throws him out, giving Plankton the formula. Fortunately, SpongeBob tries to give plankton the penny he used to distract Krabs, but inserts it in the self-destruct slot, causing Plankton to try to get back to the Chum Bucket. However, the robot explodes when he arrives, destroying the entire restaurant, and rolling the formula to SpongeBob, who realizes his mistake.
In "Life of Crime", it is revealed that Mr. Krabs stole Plankton's lawnmower from him.
In "Christmas Who", Plankton is seen singing "The Very First Christmas" with the rest of the others together, in which Mr. Krabs gives Plankton a fruitcake, though Plankton ultimately tosses it in the trash.
Season 3[]
In "The Algae's Always Greener", After failing to steal the Krabby Patty secret formula once-again, Believing Mr. Krabs to be much better off, he longs to switch lives with his arch-enemy. Karen points out the transmogrifier he conveniently has to do just that and suggests he use it. Plankton takes the transmogrifier and switches Mr. Krab' live.
Season 4[]
In "Fear of a Krabby Patty", he pretends to keep the Chum Bucket open 23 hours a day. This causes Mr. Krabs to make the Krusty Krab open 24/7 and force his employees to keep working without breaks or even going home. After 10 days, Plankton orders 10000 Krabby Patties under an alias. After 43 days of constant work, SpongeBob gains a fear of Krabby Patties and begins to see everyone as a killer patty. Plankton then poses as a psychiatrist to trick SpongeBob into telling him the formula. After several failed attempts, he tries using hypnosis, but this causes SpongeBob to get over his fear and ruin his plan.
In "Krabs vs. Plankton", after another attempt to steal the formula fails due to slipping on a wet floor, he learns Mr. Krabs doesn't use a wet floor sign. Plankton uses this as an excuse to fake an injury and sue Krabs to get the formula. Luckily, SpongeBob uses a Krabby Patty to expose Plankton's lies and help Krabs win the trial.
Season 5[]
In "Friend or Foe", Mr. Krabs tells SpongeBob his side of the story about why he and Plankton are enemies. It reveals that Mr. Krabs and Plankton were best friends from birth and did everything together. Both were outcasts, with Plankton being viewed as a nerd for his intelligence, and Mr. Krabs (ironically) being extremely poor, and victims of cold-hearted ridicule and social prejudice by a particular circle apparently led by Billy. One day, Mr. Krabs finds a penny at the carnival, his first exposure to money, which he spends on a balloon for Plankton. Later, they get enough money to buy a burger from Stinky's Burgers
which, despite having horrible food and literally being located in a dump, is very popular among the local children including Billy and his gang, due to being the only place in town to get a burger. Stinky, apparently just as shallow and mean as Billy and his group, refuses to serve them, saying that freaks like them are bad for business, and tells them to "wait" at the back of the building, only for him to yell at them again. There, they witness Stinky retiring for the day, having made millions from the stand. Plankton and Mr. Krabs decide to go into the burger business themselves and create their own burger so people will finally respect them, but no one wants to try it. When Stinky is arrested and his establishment is closed by the local health department for numerous ethical and health code violations, the two open "Plabs Burgers" on his former site, which the children are now forced to eat at, despite it being even worse than Stinky's.
Plankton says that they are now ruling the stomachs of the children, and soon will be ruling their brains. Mr. Krabs argues that it should be about satisfying the customers, rather than power. Soon, they get into an argument, and Mr. Krabs is ejected into a dump pile and tells Plankton that he will one day regret this.
Plankton comes in and disagrees with Mr. Krabs' story and tells SpongeBob his own version. His story is the same as Mr. Krabs', except that their roles during the fight at the end are reversed, with Mr. Krabs wanting to rule the money of the children.
Plankton and Mr. Krabs begin on arguing about the story until Karen arrives and tells the real story: as she had been a security camera which was installed by Plankton at the time and recorded everything.
The restaurant initially had no customers, and Old Man Jenkins was the first to try one of their burgers. Upon taking a bite, he smiles, falls to the ground, and a newspaper appears saying he knocked out by the taste of the burger. Mr. Krabs and Plankton began started to get angry and accusing each other of tainting the patty. They begin fighting over the recipe, eventually tearing it in two, with Plankton getting the bottom half, which says "...and a pinch of chum." Their friendship is over and Plankton storms out to pursue his own career in food. However, during the struggle, a shelf was knocked down, dumping various ingredients into the patty batter, creating the Krabby Patty recipe, which Krabs is left with. The two the went their separate ways, with each trying to open their own establishment. People really like Mr. Krabs' "Krabby Patty," while Plankton's Chum Burger is horrible.
After hearing the whole story about there past, Plankton and Mr. Krabs then begin to make up and apologize, only until Plankton takes the formula from his pocket. causing SpongeBob and Mr. Krabs to start chasing Karen and Plankton in circles outside the Krusty Krab.
In "Krabs a La Mode", when he learns Mr. Krabs always keeps the Krusty Krab temperature at 62 decrees and refuses to change it, Plankton gets an idea to run him out of business. He opens the freezer, leaves a sink running, and lowers the temperature to -15, freezing the restaurant solid. He then places a piece of paper over the thermostat to trick Krabs into thinking the temperature is still 62. Krabs buys this and refuses to change the temperature even after Squidward points out how cold it is. Afterwards, he tries to lead customers to the Chum Bucket by making it warmer. However, Krabs turns the Krusty Krab into an ice rink and makes more money than ever. Plankton uses this as a way to steal a Krabby Patty, but was foiled by SpongeBob and the local hockey team. He then reveals the real temperature to Mr. Krabs and uses the thermostat to freeze him solid along with SpongeBob, Squidward, and several customers. He eventually falls off the thermostat, allowing Mr. Krabs to freeze him. He is then used as a ice cube for a cup of lemonade for Mr. Krabs after he turns the Krusty Krab into a pool.

However, SpongeBob discovers that after the highway goes through Jellyfish Fields, it goes directly over the Krusty Krab before ending at the Chum Bucket's front doors. Despite SpongeBob and Patrick's efforts, the highway is built, driving Mr. Krabs out of business and forcing him to sell the formula. However, Plankton gets the karma he deserves when the jellyfish invade the Chum Bucket and severely sting Plankton before attacking the rest of Bikini Bottom.

The SpongeBob SquarePants Movie[]
| “ | Oh, grow up! What, do you think this is a game of kickball on the playground? You never had a chance to defeat me, fool! And you know why? (SpongeBob: Because you cheated?) No! Not because I cheated! Because I'm an evil genius... and you're just a kid! Haha! A stupid kid! | „ |
| ~ Plankton to SpongeBob SquarePants. |
As Mr. Krabs is being interviewed by Perch Perkins, Plankton watches in rage, envious of him for succeeding in life when he's never had a single customer. Plankton continues to lament to Karen about how he's tried every scheme to steal the Krabby Patty recipe from A to Y, and Karen informs him that there is a final letter in the alphabet; Z. Plankton discovers his "Plan Z" in the back of his filing cabinet and revels in its sinister nature, before going outside to monologue about his upcoming victory, only to be stepped on by SpongeBob, who was heading to the grand opening ceremony of the Krusty Krab 2.
That night, Plankton initiates the first phase of his plan by stealing King Neptune's precious crown (which concealed his baldness) and subsequently abandoning it in the forbidden Shell City, framing Mr. Krabs for the crime with a fake note. As a result, Neptune falls for Plankton's deception and freezes Mr. Krabs in place and allows SpongeBob and Patrick six days to retrieve the crown. Plankton then takes advantage of Mr. Krabs' frozen state and steals the Krabby Patty recipe with ease, producing Krabby Patties under the guise of preserving the Krusty Krab's legacy, also giving out free bucket helmets with each purchase, allowing the Chum Bucket to become just as popular as the Krusty Krab had been previously. When Karen points out that SpongeBob and Patrick could retrieve the crown and unravel Plankton's plan, he reveals that he had thought ahead and hired a hit man named Dennis to eliminate the two. Later, Squidward uncovers Plankton's scheme and threatens to report him to King Neptune, resulting in Plankton revealing that the bucket helmets were also minded control devices, enslaving the entire population of Bikini Bottom and turning them against Squidward. Plankton then begins turning Bikini Bottom into "Planktopolis", a city dedicated entirely to him, which Princess Mindy attempts to use as a motivation for SpongeBob and Patrick when they prepare to give up.
Even when SpongeBob and Patrick finally manage to return the crown to Neptune after defeating Dennis and the Cyclops, this still doesn't stop Plankton as he puts a mind-controlling helmet on Neptune, revealing that the theft of the crown was nothing more than a ruse to lure Neptune under his control and take over the seas for himself. Eventually, Plankton is eventually defeated by SpongeBob when he sings the "Goofy Goober Rock" to remove the bucket helmets from all of the fish. Plankton tries to escape, but gets accidentally stomped on by the citizens of Bikini Bottom and then send to jail by the Bikini Bottom Police Department while screaming that he will destroy everyone as revenge.
Despite new seasons and two sequels coming out after this movie, it's commonly assumed that the first movie is the canonical series finale, so if that were true, this would be Plankton's final fate, being condemned to life imprisonment and sent to jail for the rest of his life for his actions against Bikini Bottom and King Neptune. However, it has been confirmed that these rumors are false, so it's likely that in the typical SpongeBob "reset" button, Plankton was back on Bikini Bottom shortly afterwards.
The SpongeBob Movie: Sponge Out of Water[]
| “ | The formula, Please! (Burger-Beard: Come on! Team up with me! We'll be rich and powerful!) No, thanks. I'm already part of a teamwork. | „ |
| ~ Plankton/Plank-Ton refusing to join Burger-Beard. |
Plankton attempts to steal the Krabby Patty secret recipe, but in this conflict, it disappears when Burger-Beard writes in the magic book to steal it. Then he later becomes an anti-hero, when he begrudgingly teams up with SpongeBob who was rescuing him from Mr. Krabs and the people of Bikini Bottom falsely accuse Plankton of stealing the recipe and SpongeBob for "joining his side". Throughout the journey, SpongeBob tries to show Plankton the meaning of teamwork, much to his annoyance. Then they go time traveling to keep the secret recipe from disappearing but fails. Then Plankton, who was hiding inside SpongeBob's pocket, surprisingly appears to help out with SpongeBob, Patrick, and the others to get the Krabby Patty secret formula back from Burger-Beard (the true culprit) as superheroes.
Using the magical book that Burger-Beard stole earlier, Plankton becomes a giant muscle-bound hero (dubbing himself as Plank-Ton). After Burger-Beard defeats SpongeBob, Sandy, Patrick, Squidward, and Mr. Krabs, he attempts to escape, only for the muscle-bound Plankton to stop him by lifting up his ship. Embellished with the true meaning of teamwork, Plankton helps SpongeBob create a storm full of the bubble to capture Burger-Beard and force him to return the recipe.
After kicking Burger-Beard away to a marooned island, Plankton ponders on what to do with the formula, much to Krabs' distraught. However, Plankton decides to give the recipe back to Krabs, admitting that keeping things to himself is a selfish thing to do and gaining some fondness for the group. As everything in Bikini Bottom was turned back to normal, Plankton continues his role as the Krusty Krab's business rival going back to his recipe-stealing tricks just to keep things in the status quo. This shows that as much as he grew to care about SpongeBob, he could be beyond redemption. However, he sometimes becomes an anti-hero in the episodes after this movie showing that he did change.
The SpongeBob Movie: Sponge on the Run[]
| “ | Wait... you're giving up?! (Krabs: Oh, Plankton, I wouldn't expect you to understand. But somehow, without SpongeBob... this whole thing... just DOESN'T MAKE SENSE ANYMORE!!) You can't do that! I've spent my entire career for this moment, and you roll over like a HARPOONED WHALE?!! I WON'T LET YOU ROB ME OF MY VENGENANCE!! (Krabs: Give my regards to your loving wife. ) Heh.... this doesn't.... feel quite as good as.... (sarcastically).... yay, I won. | „ |
| ~ Plankton feeling guilty after succeeding in obtaining the Krabby Patty formula from a miserable Krabs. |
Plankton prepares to once again try to steal the recipe, knowing Mr. Krabs won't be able to stop him this time. However, Karen points out that it's SpongeBob who always stops him. When he attempts to steal the formula later that night, SpongeBob stops him, proving that Karen is right.
Plankton then learns he has to get rid of SpongeBob to get the recipe. After learning that King Poseidon, the king of the lost city of Atlantic city, needs a new snail to get rid of his face wrinkles, Plankton sells SpongeBob's snail Gary to Poseidon and then gives SpongeBob and Patrick a car to go there and save Gary. Driving the car is a robot named Otto - who was built by Sandy who gave it to Mr. Krabs who then threw it out. SpongeBob and Patrick hop the car and Plankton orders Otto to take them to the lost city of Atlantic city and never come back. SpongeBob, Patrick and Otto leave and Plankton then celebrates SpongeBob being gone, knowing he won't be able to stop him from getting the recipe.
Sometime later, business at the Krusty Krab has gone down, and Plankton comes over to gloat against Mr. Krabs, who miserably gives the secret formula to Plankton. Despite having succeeded in obtaining the secret formula once again, Plankton is utterly shocked to see Krabs in his lowest as the latter is extremely miserable over SpongeBob's disappearance; even finding his own success in obtaining the formula to be quite boring. Later in the film, when Mr. Krabs, Sandy and Squidward learn that SpongeBob and Patrick have been captured by Poseidon and agree they have to go there to save them, Plankton, feeling guilty, offers to come along with them by confessing of what he did. The four of them quickly drive to Atlantic City, enter Poseidon's lounge and rescue SpongeBob, Patrick and Gary and quickly retreat with Poseidon's guards chasing them. After SpongeBob stands up to Poseidon and convinces him to let SpongeBob and the gang go home free with Gary, Bikini Bottom becomes a sanctuary for snails and Plankton is shown to have adopted a snail at the end. Afterwards, Plankton goes back to the chum bucket to think of a new plan, but promises that he will never make the same mistake of taking SpongeBob out of town again.
The events of Sponge on the Run are most likely non-canonical to the main series, given many continuity errors and the implication that it serves more as a pilot for the upcoming Kamp Koral spin-off series.
Saving Bikini Bottom: The Sandy Cheeks Movie[]
| “ | If I can get my hands on their machine, I can finally turn myself into an unstoppable army and rule the world! (laughs diabolically) | „ |
| ~ Plankton planing to clone himself to create an unstoppable army and rule the world. |
Plankton appeared as a minor antagonist. He is first seen dancing with the other characters in the Bikini Bottom until he gets stomped on.
He is next seen sadistically seeing everyone running in terror when the Bikini Bottom gets taken away into the surface.
Plankton and Karen have the only notable scene in the movie when they see that Sue Nahmee has a cloning machine. Karen tells her husband to prefer in using the better cloning machine unlike his. Plankton makes a new scheme in escaping a giant fish bowl holding the Bikini Bottom by being picked by humans and cloning himself to create an unstoppable army and rule the world, but Karen also informs him to take out the trash before carrying out his evil scheme.
Plankton is last seen hurrying outside until the human scientists picked Mr. Krabs and Squidward instead of him. With his evil plan quickly foiled, Plankton sadly feels defeated while walking back to the Chum Bucket, commenting "This is like high school all over again." He isn't seen again for the rest of the movie.
Plankton: The Movie[]
Plankton appears as the protagonist of the movie. It was told in his backstory that he felt tired being let down by his family before leaving them to head over for college. It also turns out that he created Karen with the usage of a calculator connected to a potato in a Petri dish to assume as his only friend. During college days, he upgraded Karen to her current form and planted four chips to define her personality (empathy, intelligence, evil and sassiness). It also turns out that Plankton made his life's goal to steal the Krabby Patty recipe after hearing Krabs jokingly say that the formula would help him take over the world.
After failing in his latest attempt to steal the Krabby Patty formula again, Plankton is shocked to see that Karen has converted the Chum Bucket into a successful Mexican-themed chum restaurant with an active customer base (even SpongeBob is among them). However, Plankton is completely ungrateful (as he thinks that Karen's idea doesn't fit his expectations of evil) and furiously burns the place down and drives all the customers away with a flamethrower. Unfortunately, this proves to be biggest mistake as it drove Karen extremely angry, that she purposely disposes her empathy chip before transforming into a more dangerous mech, creating the Hydra Karens in the process. Plankton and SpongeBob then watch in horror as Karen uses all of Bikini Bottom's buildings (including the Chum Bucket and the Krusty Krab) to form her giant robot to take over the world for herself.
Rather than taking responsibility for his actions, Plankton instead decides to finish off Karen by creating a New Karen to combat the Hydra Karens, but this only causes all the Karens to merge together, causing her to be more powerful than ever. She then attempts to kill Plankton, only for SpongeBob and the Gal Pals (Sandy, Pearl and Mrs. Puff) to rescue him. Taking refuge in their underground lair, the Gal Pals angrily berate Plankton for his actions that made Karen angry in the first place and demand that he apologize to her. However, Plankton is incapable of making an apology, so the Gal Pals placed Karen's empathy chip inside his brain, leaving him to have a revelation about his actions.
SpongeBob and the Gal Pals then bring Plankton over to Karen's robot, where they managed to destroy New Karen and the Hydra Karens before having Plankton to head up to confront Karen in person. Having understand the folly of his actions after pulling out the empathy chip from his brain, Plankton finally apologizes to Karen, but she rebuffs him by offering the Krabby Patty formula to him in order to get him to leave. However, Plankton discards the formula by saying that Karen is his 'real secret fomrula', which finally drove Karen to reconcile with him, just as the giant robot gets crumbled apart (due to Patrick eating the potatoes powering up the robot).
As Bikini Bottom gets reverted back to its former glory, Plankton and Karen find themselves being confronted by the angry citizens, who all vow to attack them both for their actions. However, SpongeBob convinces the citizens to let it go by saying that he's a 'sucker for a love story', to which everyone agrees and celebrates.

| “ | (Karen: With you, there’s always another plan.) Quiet, computer wife! This time, it’ll work! I’ll make everyone love my Chum Burgers through the power of hypnosis. It’s almost too easy. Soon they’ll all see; I may be small, but my genius is immense! (Karen: Come on, Sheldon. It’d take forever to hypnotize this whole town.) You used to enjoy my evil schemes... (Karen: What can I say? After twenty years of marriage, the magic’s gone.) | „ |
| ~ Plankton and Karen's argument over yet another one of Plankton's schemes at the beginning of the show. |
Introduced as Mr. Krab's diabolical rival who wishes to run the Krusty Krab out of business, during the events of the musical, it's revealed that his marriage with Karen is on the rocks due to his schemes always ending up in smoke. However, when nearby volcano "Mount Humongous" starts erupting, Plankton gets to work on a scheme. Knowing that the town is in chaos due to their impending doom, Plankton decides to advertise an escape pod to take the entirety of Bikini Bottom to a new home via his song "When the Going Gets Tough". Unbeknownst to them, however, Plankton plans to use the pod to hypnotize the entire town into loving his chum, creating a newfound dystopia for the food. Problem is, the escape pod is much more expensive than the struggling business could ever afford, so the rest of the town decides to host a charity concert in order to raise enough money to escape. With this underway, it seemed like Plankton's plan could actually work this time.
That is, until SpongeBob and Sandy come up with a plan to interrupt the volcanic blast with Sandy's latest invention "The Erupter-Interrupter". Enraged at this new development, Plankton starts panicking before Karen arrives, having found Plankton's old Avalanche Maker 3000. Having Karen's love for Plankton's schemes reignited, as well as her love for him in general, the two kiss before launching a laser onto the sponge and squirrel.
However, due to SpongeBob and Sandy's determination (and a trusty jetpack save from Patrick), Plankton's plan falls apart at the seams. Plankton and Karen, not knowing that their scheme had failed, tries to gather up everyone in Bikini Bottom into the escape pod, only to realize that the charity concert's main hosts, the Electric Skates, left before the show even began, thus meaning that no money was raised. Everyone starts arguing before the main trio shows up and tries to calm everybody down. As the sun sets, the town, Plankton included, braces for impact before realizing that Sandy's invention worked, preventing the volcano from going off. Plankton, though relieved, becomes enraged that yet another one of his evil schemes failed, revealing his true intentions to the entire Bikini Bottom. While now proven guilty, he and Karen are ultimately let off the hook, and the two of them perform during the musical's final song before leaving to work on another plan.
