Villain Overview

Hear me, Krabs. When I discover the formula for Krabby Patties, I'll run you out of business. I WENT TO COLLEGE!!
~ Plankton's first quote.
But it's becoming increasingly obvious. I can deny it no longer!... I am small.
~ Plankton's most famous quote.

Sheldon J. Plankton (simply known as Plankton) is the main antagonist of Nickelodeon's animated TV franchise, SpongeBob SquarePants. He is the business rival and archenemy of Mr. Krabs and Spongebob.

He runs an unsuccessful restaurant called the Chum Bucket along with his wife/sidekick Karen, and constantly plots to both expand his business (usually by stealing the Krabby Patty secret recipe) and eventually take over the world. He serves as the main antagonist of the show's first theatrical film The SpongeBob SquarePants Movie, the anti-heroic deuteragonist of its second theatrical film The SpongeBob Movie: Sponge Out of Water and the overarching antagonist turned supporting character in the show's third theatrical film The SpongeBob Movie: Sponge on The Run.

He is voiced by Doug Lawrence, who also voiced Edward Platypus in Camp Lazlo and Filburt Turtle in Rocko's Modern Life. In the musical adaptation, he was portrayed by Wesley Taylor.


Plankton is shown to be an evil mastermind through and through, with signs of having a napoleonic complex due to his very short stature. His plans always involve technological devices and weapons, all for the sake of the formula. Although sometimes, he merely wants to expand his business or ruin the Krusty Krab. His main goal has always been throwing the Krusty Krab out of business. In Seasons 1 to 5, he was shown to be a poor businessman, being completely unable to acquire any success for his Chum Bucket restaurant (as a majority of his schemes involving attempted theft of the Krabby Patty recipe). However, in both events of the first movie and later seasons (which chronologically still set between the first film and season 5), he was now able to get more chances of success other than stealing the Krabby Patty formula, such as having an attractive restaurant place where the people will come to observe the underground complex beneath both his and Krabs' restaurant. Other examples are putting slogans such as "Chum is Fum" and "Fum is Chum" (where Patrick Star helped him in his slogans until the starfish's both low IQ and literally overheated brain became the setbacks) and one person named Nat Peterson kept coming to buy chum to eat, although he was only doing it since Karen paid him to do so. Therefore, his poor business skills are mostly because of his lack of foresight.

All in all, Plankton's small stature, the fact pretty much everyone else in his life looks down on him, and his poverty all-cause Plankton to feel very insecure and even defensive. He clearly suffers Napoleon syndrome, and his desire for conquest stems from his deep-seated desire for respect, and even admiration, both of which are absent from his life. From his childhood of poverty, all the way to his adulthood of feeling neglected, and downtrodden, his bitterness and hatred of nearly everyone has grown, and consumed him, almost molding him into a full-fledged psychopath who brings a lot of his bad luck on himself. However, traces of empathy are to be found, as he truly loved Spot, his pet amoeba, and even though he seems to look down on, belittles Karen, as he does actually love her, and Karen returns this love in spite of often being snarky to him, much to Plankton's frustration. Furthermore, during the second movie, he expressed his love for Karen before she shut herself down, so that he and SpongeBob could time travel.

Also, it is worth mentioning, due to his small size, and the fact he tends to have huge flaws in all his plans, no one in Bikini Bottom really sees Plankton as a threat, let alone is aware of his presence in the town or what he will do. For instance, when Sandy managed to capture Plankton for stealing her fur, the police arrested her instead for her unintentional public nudity and barely notice his presence in spite of him being in extremely close proximity. Most people who know him and aware of his presence in Bikini Bottom merely see him as a pest and dismissed him as a mere annoyance. Only a handful individuals who aware with how dangerous Plankton can be: Mr. Krabs, who acknowledges that if he DID get the formula, he would make the Chum Bucket a bigger risk to the Krusty Krab that made him vigilant around Plankton (though this doesn't stop Mr. Krabs from mocking him); and SpongeBob, whom was truly afraid of him and his outlandish schemes, especially since the events of his debut episode where he used a mind-control on the sponge and nearly discovered the Krabby Patty's formula in the process (though failed, this was enough to alarm SpongeBob about Plankton's villainous qualities and dangers that he can pose to the others).

While Plankton often appears as a bumbling comic foil, he actually can be a real threat under certain circumstances, manipulating others to get his way, and when the odds are in his favor, he can be surprisingly successful, though this success is usually short-lived. Even his first appearance has him lose because of his bad luck as his scheme proved made him a dangerous threat to SpongeBob.

In the newer episodes, he has become less evil and more similar to an anti-hero as he even helps SpongeBob when they're outside of their businesses, and has occasionally shown a more good-hearted side of him as a result. However, he is still as mischievous and calculating as ever, and is still willing to exploit SpongeBob's gullibility to his own advantage.



Before the events of the series, Sheldon J. Plankton was born on the same day as Mr. Krabs where both the two would later meet each as babies.

During his childhood with him, Both Plankton and Krabs were considered outcasts by the other kids, 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.

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." 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 chumburgers 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. Plankton later named his restaurant the Chum Bucket, after the secret ingredient of the original unsuccessful patty recipe. Mr. Krabs named his restaurant the Krusty Krab, after himself.

To this very day, Plankton has been single-mindedly obsessed with obtaining the Krabby Patty formula and running the Krusty Krab out of business. 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.


Plankton works with the help of his sidekick/wife by the name of Karen, a sentient computer who gives him most of his evil plans. He is a planktonic copepod and the business rival of Mr. Krabs, the owner of the Krusty Krab where SpongeBob SquarePants works. Despite being portrayed as an antagonist in most incarnations, he frequently appears as an anti-hero (an example being the second movie The SpongeBob Movie: Sponge Out Of Water) and he has that role in almost all the newer episodes.

While the Krusty Krab is popular among the sea creatures of Bikini Bottom, Plankton's own restaurant, the Chum Bucket, gets little to no customers. Plankton's plans all revolve around stealing the elusive "Krabby Patty Secret Recipe", so that he can copy it and make the Chum Bucket popular. He lives inside his restaurant, where he has an elaborate laboratory that contains Karen's system.


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 first appears 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. Mr. Krabs explains to SpongeBob Plankton uses mind control to obtain the Krabby Patty formula Bucket. 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, whileSpongeBob 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 Aas Bubble Bass chases Plankton around his hand with him screaming.

In "Sleepy Time", Plankton's dram was revealed to be a giant causing destruction in Bikini Bottom, he then ppeared 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 him a valetine candy on valentine's day.

In "Walking Small", Plankton (in his bulldozer) attemps 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 as He 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.

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.

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.

In The SpongeBob SquarePants Movie, Plankton serves as the main antagonist of the film, and it marks the first time when he becomes an alarmingly dangerous and depraved villain of the franchise. 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 Two.

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. As a result, Neptune 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 hitman named Dennis to destroy 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 is then arrested for his crimes of turning everyone in Bikini Bottom into his slaves, stealing Neptune's crown, and scapegoating Mr. Krabs where he gets sent to jail.

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 returns in the 2015 film The SpongeBob Movie: Sponge Out of Water as the secondary antagonist turned deuteragonist. He 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 into 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 became more like an antihero in the episodes after this movie showing that he did change.

The SpongeBob Movie: Sponge on the Run

Plankton returns in the 2020 film, The SpongeBob Movie: Sponge on the Run. He starts out as the secondary antagonist of the third film, but later becomes a supporting character. He 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. Mr. Krabs, who is miserable with SpongeBob gone, gives Plankton the recipe but Plankton is surprised that Mr. Krabs is just giving up.


Battle For Bikini Bottom/Battle for Bikini Bottom - Rehydrated

Main article: Robot Plankton

Plankton appears in the 2003 videogame and its 2020 remake. He initially was the main antagonist of the game, but this is a trick by Robot Plankton, the true main antagonist of the game.

In this game, Plankton creates an army of robots to take over Bikini Bottom but forgets to make them obey him, causing his creations to run amok across the sea bottom. Plankton uses SpongeBob, who is convinced that he caused the robot invasion while role-playing with Patrick, to get rid of the robots, which are led by a Robotic Plankton.

Nicktoons Unite!

Plankton is one of the villains who compose The Evil Syndicate (along with Professor Calamitous, Denzel Quincy Crocker, and Vlad Plasmius), the main antagonists of the game. Plankton was recruited into the team by Professor Calamitous. He was charged to harvest energy out of the jellyfishes in Jellyfish Fields for the Doomsday Machine that the Syndicate was building, making changes in the Chum Bucket to make it a factory. He also began to kidnap citizens of Bikini Bottom (including Patrick) who didn't go along with his plans. He also captured Mr. Krabs to force him to give him the Krabby Patty Formula. However, the group of heroes composed of Spongebob, Jimmy Neutron, Danny Phantom and Timmy Turner with the help of Sandy Cheeks managed to free the jellyfishes and defeat Plankton at the Chum Bucket. He retreated to Retroville where he tried to destroy the heroes along with his fellow Syndicate members. But even that failed as his shield was turned off and he was defeated again by SpongeBob.

Nicktoons: Battle for Volcano Island

Although Plankton nor any of his fellow Syndicate members appear in this game, he is mentioned by Spongebob when he and Danny come across his giant robot on the beach that was pulled by the rip caused by The Mawgu, with Spongabob and Danny discussing his previous defeat.

Nicktoons: Globs of Doom

Plankton returns in this game as the only original member to be part of the second Syndicate. He, along with other villains (Nicolai Technus, Beautiful Gorgeous, Traloc, and Dib), join forces with the heroes to gather parts for the Vessel of Portentia and defeat the Morphoids. However, he also betrays the heroes at the end when they are about to defeat Globulous Maximus and the villains steal the Vessel. However, he and the others were defeated when Maximus takes them one-on-one at the moon, destroying the Vessel and leaving them in the vacuum of space.

Nicktoons Racing

Plankton appears as the hidden main antagonist of the game. In the beginning, he is making invitations and sending them to Nicktoon characters, attracting their attention to a race. He then arrives at the race in his own car that completely hides his identity. At the end of the race, it was revealed that the prize of the race was a lifetime supply of Krabby Patties, which Plankton's car showed up, revealing that Plankton was the mysterious rider. He is an unlockable playable character in the game, the player can play as him after beating all cups on Easy.


The SpongeBob SquarePants Movie

Curses! It's not fair. Krabs is being interviewed by Perch Perkins, and I've never even had one customer!
~ Plankton ranting about Mr. Krabs' success in opening the Krusty Krab 2 and that he never had any customer at the Chum Bucket.
Oh, Karen, my computer wife, if only I could have managed to steal the secret to Krabs' success, the formula for the Krabby Patty. Then people would line up to eat at my restaurant. Lord knows I've tried.
~ Plankton confiding in Karen his wishes to obtain the Krabby Patty formula
I've exhausted every evil plan in my filing cabinet...from A to Y. (Karen: A to Y?) Yeah, A to Y. You know the alphabet. (Karen: What about Z?) Z? (Karen: Z. The letter after Y.) W, X, Y, Z. Plan Z! Here it is, just like you said. (Karen: Oh, boy.) Oh! Oh! Ohhh! It's evil. It's diabolical. It's lemon-scented. This Plan Z can't possibly fail!
~ Plankton deciding to use Plan Z, adamant that it will not fail
So enjoy today, Mr. Krabs, because by tomorrow, I'll have the formula. Then everyone will eat at the Chum Bucket, and I will rule the world! All hail Plankton. All hail Plank...! Ow! (SpongeBob: I'm ready! Promotion! Ew, I think I stepped in something!) Not in something, on someone, you twit! (SpongeBob: Oh, Sorry, Plankton. Are you on your way to the grand opening ceremony?) No, I am not on my way over to the grand-opening ceremony. I'm busy planning to rule the world! (SpongeBob: Well, good luck with that. I'm ready. Promotion. I'm ready. Promotion.) Stupid kid.
~ Plankton telling SpongeBob he does not have time to go to the grand-opening ceremony while being busy plotting to rule Bikini Bottom.
Time to put Plan Z into effect. Starting at the undersea castle of King Neptune.
~ Plankton going to King Neptune's castle to steal his crown and frame Mr. Krabs for the theft.
I got it. I got it!
~ Plankton succeeding in stealing Neptune's crown.
Hi, Mr. Krabs. This is Clay, the guy you sold Neptune's crown to. Yeah, I just wanted to say thanks again for selling me the crown. Neptune's crown. I sold it to a guy in Shell City, and I just wanted to say thanks again for selling me the crown. Neptune's crown. Which is now in Shell City. Goodbye.
~ Plankton, through a fake phone call, misleading a furious Neptune into assuming that Mr. Krabs sold his crown to Shell City
Plan Z. I love Plan Z.
~ Plankton goating about his success after tricking Neptune who yells in frustration
Ding-a-ling. Hey there, old buddy. Freeze! One secret formula to go, please. No, no, don't trouble yourself. I'll get it. Well, I'd like to hang around, but I've got Krabby Patties to make... over at the Chum Bucket. Plan Z, I love ya!
~ Plankton taunting an already frozen Mr. Krabs as he gets the formula and goes back to the Chum Bucket.
(Perch Perkins: Excuse me, Plankton. Perch Perkins, Bikini Bottom News. Can I get a minute?) Anything for you, Perch. (Perch Perkins: All of Bikini Bottom wants to know, how did you get the Krabby Patty?) Well, Perch, before my dear friend Eugene Krabs was frozen by King Neptune... I'm sorry. He confided in me a secret wish. "Sell the Krabby Patty in my absence at the Chum Bucket," he said. "Don't let the flame die out." (fake sobs) By the way, act now and you get a free Chum Bucket bucket helmet with every purchase. Here you go, Perch. (Perch Perkins: Thanks.) Bucket helmets for everyone!
~ Plankton being interviewed by Perch Perkins about how did he get the Krabby Patty and offering bucket helmets to everyone.
Karen, baby, I haven't felt this giddy since the day you agreed to be my wife. (Karen: I never agreed.) Evil Plan Z is working perfectly. Nothing can stop me now! (Karen: Nothing except SpongeBob and his pink friend. My sensors indicate that they're going after the crown. If they make it back, Neptune might discover some fingerprints. Tiny fingerprints. Stubby, tiny fingerprints.) Evil Plan Z is way ahead of you, baby. I've already hired someone to take care of those two. He's a vicious, cold-blooded predator!
~ Plankton assuring Karen that he hired a hitman to prevent SpongeBob and Patrick from retrieving the crown.
(Squidward: So you're selling Krabby Patties, eh, Plankton?) That's right, Squidward. And there's a free bucket helmet with every purchase. Care for one? (Squidward: No. You may have hoodwinked everyone else in this backwater town, but you can't fool me. I listen to public radio.) What's that supposed to mean? (Squidward: It means you set up Mr. Krabs. You stole the crown so Neptune would freeze him and you could finally get your stubby little paws on the Krabby Patty formula. [Plankton looks at his hands] It was you all along. But you made one fatal mistake. You messed with my paycheck. And I'm gonna report you to the highest authority in the land, King Neptune!) We'll see about that, Inspector Looselips.
~ Plankton prepares to capture Squidward so he can't tell the truth to King Neptune.
(Karen: Now activating helmet brain control devices.) (Squidward: Huh?) (A radar rises out of the Chum Bucket restaurant, and the helmets on the people's heads cover their faces. They all stand up and drone: All hail Plankton.) (Squidward: What's going on here?) (Plankton puts his headphones on) Seize him, slaves! (Drones: All hail Plankton.) (Squidward: Ah! I'm getting out of here!) (Squidward tries to escape the Chum Bucket, but runs into other drones and he runs into the corner. Everyone marches toward him as they continue droning "All hail Plankton". Squidward screams in terror) (Plankton chuckles evilly) Who can stop me now?! (laughing) WHO?!
~ Plankton turning the people in Bikini Bottom into slaves.
No resting! This monument celebrating my glory isn't gonna build itself. Move faster!
~ Plankton pressuring his slaves into building Planktopolis.
Sorry about this calendar. March 14. Wait, that's not right. It should say "The day that Krabs fries!" Guess who's here.
~ Plankton planning to have Mr. Krabs executed by King Neptune.
This is the best seat in the house. All right, Neptune, let's get it on!
~ Plankton before Mr. Krabs' execution.
(King Neptune: Eugene Krabs, the time has come...) (Mindy: No.) Yes. (King Neptune: ...for you...) (Mindy: No.) Yes. (King Neptune: fry...) (Mindy: No.) Yes.
~ Plankton cheering on Neptune while the latter attempts to execute Mr. Krabs mere seconds before Spongebob and Patrick return with the crown
Oh, yes. Well done, SpongeBoob. (SpongeBob: Sorry to rain on your parade, Plankton.) Oh, don't worry about me. My parade shall be quite dry under my umbrella! (Spongebob, Patrick and Mindy: Umbrella?) [A bucket helmet falls on Neptune's head while unsuccessfully trying to take it off] (Mindy: Daddy, no.) Daddy, yes. (King Neptune: All hail Plankton.) [Spongebob, Patrick and Mindy scream in terror before the other mind-controlled slaves storm into the Krusty Krab 2 and Neptune aims his trident at the three of them]
~ Plankton sarcastically complimenting SpongeBob before mind-controlling King Neptune.
(Patrick: Spongebob, what happened?) (SpongeBob: Plankton cheated.) Cheated? Hold on there, baldy. Oh, grow up. What, 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. A stupid kid!
~ Plankton mocking SpongeBob and calling him a stupid kid. [Plankton, Neptune and the other slaves laugh at Spongebob
His dance moves are impressive, but I'm in control. Seize him!
~ Plankton ordering his slaves to capture SpongeBob only for them to be blasted away by the latter.
What? No! My precious helmets!
~ Plankton yelling in total defeat while SpongeBob frees the mind-controlled Bikini Bottom residents.
Come on, I was just kidding. Come on, you guys knew that, didn't you? With the helmets and the big monuments...Wasn't that hilarious, everybody? I will destroy all of you!
~ Plankton's last words in the first film before he is sent away to prison.


  • Plankton found Mr. Krabs' life to be worse than his own when he experienced it in "The Algae's Always Greener" and "Spy Buddies". In "The Algae's Always Greener", he found lots of reasons that make Mr. Krabs' life difficult:
    • SpongeBob is always asking him for a Weekly Performance Review on Tuesday and throws a temper tantrum if Plankton refuses. He also keeps yelling "SOILED IT! SOILED IT! SOILED IT!" when he accidentally gave a customer a large soda when the customer wanted a medium soda.
    • Squidward, the lazy, grumpy, pessimistic worker at the restaurant, complains to Plankton that he doesn't want to work with SpongeBob. Later, when Plankton put him in charge of fry cooking, a customer got angry because the Krabby Patty that Squidward cooked was very ugly, disgusting-looking, and hideous.
    • Pearl, his virtual reality daughter, throws a big temper tantrum because she doesn't get more than $1 advance to her allowance.
    • Krabs tries to steal the Krabby Patty formula (which Plankton actually does in the show's reality), and Krabs NEVER gives up like he does. This version of Krabs, while not as smart as Plankton, is even more unhinged in his attempts.
  • In The SpongeBob SquarePants Movie, Plankton was a lot more evil and depraved than he was in the series as he was ultimately grown into an alarmingly dangerous threat to the entire ocean. In the said movie, he stole King Neptune's crown, frames Mr. Krabs for it, sends Dennis to kill SpongeBob and Patrick rather than merely get rid of them, enslaves Bikini Bottom (which also includes not allowing his slaves to earn a single rest or break and just work nonstop) and shows excitement and joy when Mr. Krabs is going to be killed (in spite of their former friendship, though his past relationship with Krabs had yet to be established when the movie came out). He also enslaved King Neptune, in which gave him a potentially powerful asset in conquering the whole ocean and the world.
    • However, it is revealed that Burger-Beard had previously surpassed Plankton (if one count the second movie as prequel to the first film) as aside managed to instantly steal the Krabby Patty recipe simply by rewriting the magic book that records everything that occurs in the ocean (especially events in Bikini Bottom includes conflict between Plankton and Krabs), the pirate was able to destroy Bikini Bottom and render it into post-apocalypse state in an instant. Even in order to defeat Burger Beard, it took the superpowered SpongeBob, Sandy, Patrick, Krabs, Squidward, and Plankton himself to defeat him.
  • Early in the series, Plankton is considered a true villain. Later, as Krabs becomes more dramatically greedy (said greed ultimately drove him insane) and Plankton becomes less dramatically evil and less of a genius, the role of the main villain of the series becomes more debatable as lots of people think that Mr. Krabs is evil. Plankton also acknowledges this himself when he begins to question whether he or Krabs is truly evil. On the other hand, once seasons 9-12 started reducing Mr. Krabs' less pleasant traits, Plankton ended up becoming the true villain again. Even then, it depends on who is writing the episode.
  • He and Mr. Krabs were born exactly on the same date.
  • He mightn't became Big Bad at first, because Steven Hillenburg didn't know what to do with him, but Mr. Lawrence are liked him and so create many ideas how to use him.
