Description

Plankton works with the help of his sidekick/wife, 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 computer system.

Appearance

Plankton is a tiny green planktonic copepod. He has short arms and legs, a big yellow eye, and a red pupil with one large eyebrow. He has two long antennae on his head with spikes alongside both. He also has big white straight teeth.

Personality

Plankton is shown to be a selfish and evil genius through and through, with anger issues and signs of having a Napoleonic complex due to his very short stature. His plans always involve technological devices and weapons, all designed to aid his attempts at stealing 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, Plankton 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 involve him trying to steal the Krabby Patty recipe).

However, in both the events of the first movie and later seasons he is able to get more chances of success other than stealing the Krabby Patty formula, such as having an attractive restaurant where the people will come to observe the underground complex beneath both his and Krabs' restaurants. Other examples include 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 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. He also had Squidward make his chum edible and delicious, but one bad move on Squidward's part led to the customers tearing the Chum Bucket apart. Therefore, Plankton's poor business skills are mostly because of his lack of foresight. However in Plankton: The Movie, he was so dead set on obtaining the secret formula that he'd rather succeed in obtaining it than have a successful restaurant, as he chased out all his customers after Karen managed to make the Chum Bucket successful.

Plankton's small stature, the fact that pretty much everyone else in his life looks down on him, and his poverty all cause Plankton to feel very insecure and even defensive. 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 neglect, 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 can still be found in Plankton. For example, he truly loved Spot, his pet amoeba. Even though he seems to look down on and belittles Karen, 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, Plankton expresses his love for Karen before she shuts herself down, so that he and SpongeBob can time travel.

Due to his small size and the fact that he tends to have huge flaws in all of 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 manages to capture Plankton for stealing her fur, the police arrests 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 Plankton or are aware of his presence in Bikini Bottom merely see him as a pest and a mere annoyance. Only a handful of individuals are aware of how dangerous Plankton can be, including: Mr. Krabs, who acknowledges that if he DID get the formula, he would make the Chum Bucket a bigger risk to the Krusty Krab, which makes him vigilant around Plankton (though this doesn't stop Mr. Krabs from mocking him); and SpongeBob, who is truly afraid of him and his outlandish schemes, especially since the events of his debut episode where he uses a mind-control device on the sponge and nearly discovers the Krabby Patty formula in the process (though failed, this was enough to alarm SpongeBob about Plankton's villainous qualities and the danger that he can pose to 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 that he was 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 even helping take down Burger-Beard. However, he is still as mischievous and calculating as ever, and is still willing to exploit SpongeBob's gullibility to his own advantage, like when he had SpongeBob help him come up with an anniversary gift for Karen so that she'd give him the secret formula. However, SpongeBob didn't know about that until the end of the episode.

~ Plankton gloating 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?
Plankton: Anything for you, Perch.
Perch Perkins: All of Bikini Bottom wants to know, how did you get the Krabby Patty?
Plankton: 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." By the way, act now and you get a free Chum Bucket bucket helmet with every purchase. Here you go, Perch.
Plankton: Perch Perkins: Thanks.
Plankton: Bucket helmets for everyone!
~ Plankton being interviewed by Perch Perkins about how did he get the Krabby Patty and offering bucket helmets to everyone.
Plankton: Karen, baby, I haven't felt this giddy since the day you agreed to be my wife.
Karen: I never agreed.
Plankton: Evil Plan Z is working perfectly. Nothing can stop me now!
Plankton: 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.
Plankton: 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?
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.
Plankton: 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. 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!
Plankton: 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: Seize him, slaves!
Slaves: All hail Plankton.
Squidward: Ah! I'm getting out of here.
(Squidward tries to escape the Chum Bucket, but runs into other slaves and he runs into the corner. Everyone marches toward him as they continue droning "All hail Plankton". Squidward screams in terror.)
Plankton: Who can stop me now?! WHO?!
~ Plankton rising to power while 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.
Plankton: Yes.
King Neptune: ...for you...
Mindy: No.
Plankton: Yes.
King Neptune: ...to fry...
Mindy: No.
Plankton: Yes.
~ Plankton cheering on Neptune while the latter attempts to execute Mr. Krabs mere seconds before Spongebob and Patrick return with the crown
Plankton: Oh, yes. Well done, SpongeBoob.
SpongeBob: Sorry to rain on your parade, Plankton.
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!
Plankton: 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.
Plankton: 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?
Plankton: 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. (Cop uses a shovel to pick up Plankton) Come on, you guys knew that, didn't you? (Gets thrown into a small police car) With the helmets and the big monuments...Wasn't that hilarious, everybody? (getting drove away) I WILL DESTROY ALL OF YOU!
~ Plankton's last words in the first film before he is sent away to prison.

The SpongeBob Movie: Sponge Out Of Water

Welcome to Air Plankton! Please put your seat backs and tray tables up as we're now approaching our final destination.
~ Plankton in Sponge Out of Water.
Mr. Krabs: Where is my formula Plankton?
Plankton: I don't know, it just disappeared.
Mr. Krabs: WHY SHOULD I BELIEVE YOU, YOU LYING LIAR?!
~ Mr. Krabs enraged overseeing that his formula is missing.
Mr. Krabs: Enough with the niceties, Plankton! This is the last time I'm gonna ask ya: WHERE IS ME FORMULAR?!
Plankton: I told you, Krabs, I don't have it!
Mr. Krabs: Wrong answer! [Nearly steps on Plankton]
~ Mr. Krabs falsely accusing Plankton of stealing the Krabby Patty formula, before nearly killing him
Hands in the middle? No, no. That's sounds idiotic. Besides the two of us are no match for that angry mob!
~ Plankton with SpongeBob in Sponge Out of Water.
Plankton: Well, yeah, looks like they're gonna have to change the name of Bikini Bottom to Dirty Bottom [laughs] right SpongeBob?
SpongeBob: That's kinda gross, Plankton.
Plankton: Yeah, yeah, too soon, huh?
~ SpongeBob and Plankton.
If we could build the time machine, we can go back to time before the formula disappeared, before society broke down, before we became a hunted!
~ Plankton to SpongeBob about time travelling idea.
According to my calculation, the Krusty Krab should be right here.
~ Plankton after time travelling with SpongeBob.
SpongeBob: Well, Plankton, I guess we failed to accomplish our goals.
Plankton: We?
SpongeBob: But, even failure hurts a little less when you do it as a team, right?
Plankton: THIS IS ALL YOUR FAULT!!! (Everyone pauses and the crowd gasps.)
SpongeBob: My fault?!
Plankton: You're the one who stole the wrong secret formula!
SpongeBob: I didn't know there were two bottles.
Plankton: Of course you didn't! 'Cause you got cotton candy for brains! (The crowd goes "ooh".) No, seriously, he really does.
SpongeBob: Well, we wouldn't even be in this mess in the first place if you weren't so selfish and evil!
Plankton: I was selfish and evil until you ruined everything with your
teamwork!
SpongeBob: (Gasps) You take that back!
Plankton: YOU ARE THE WORST TEAMMATE EVER!!!
SpongeBob: NOOOOOOO!!!!!!
~ Plankton’s angry breakdown as he blames SpongeBob for stealing the wrong secret formula.
I'll show you a happy ending.
~ Plankton as he lifts up the pen and starts to write on the page.
Plankton/PlankTON: The formula, please.
Burger Beard: Come on. Team up with me. We'll be rich and powerful! Huh?
Plankton/PlankTON: No, thanks. I'm already part of a teamwork.
~ Plankton refusing to work with Burger Beard when he unsuccessfully trying to get him to join him.
Plankton/PlankTON: Here you go, Krabs.
Mr. Krabs/Sir Pinch-a-lot: Huh?
Plankton/PlankTON: She's all yours.
Mr. Krabs/Sir Pinch-a-lot: This doesn't have another insulting note in it, does it?
Plankton/PlankTON: No, that's the old me. The one who turned his back on everything important just to have that formula all to himself. But I realize now that keeping something to myself is... (He hesitates.) ...selfish.
SpongeBob/Invincibubble: Especially when that something is the Krabby Patty.

~ Plankton willingly gives Mr. Krabs the formula back.

Trivia

  • 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 Squidward in charge of fry cooking, a customer got angry because the Krabby Patty that he 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 on 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.
  • 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.
    • Though speculative, Plankton's post-first movie seasons portrayal could be attributed to newer showrunners involved misunderstanding his character as much as the rest of the main cast. In this case, they erroneously found Plankton a better anti-hero than Mr. Krabs hence the series' flanderization throughout those seasons in which Plankton became increasingly sympathetic just as Krabs became increasingly detestable.
  • He and Mr. Krabs were born exactly on the same date.
  • He may not have become the main antagonist at first because Stephen Hillenburg didn't know what to do with him. However, Mr. Lawrence liked him, and he created many ideas on how to use him.
  • For some reason, Plankton doesn't attempt to steal a to-go meal from people leaving the Krusty Krab.
  • Despite his genius, Plankton doesn't try inventing a device to scan and replicate the taste memory of a person who ate a Krabby Patty.
  • Given the main cast of SpongeBob has been compared to the Seven Deadly Sins, Plankton obviously embodies Envy. Ironically, Envy is called the "little green monster", which kids unfamiliar with aquatic life would call Plankton. Plankton's jealousy towards Krabs' success drives him to try stealing the Krabby Patty formula.
  • In real life, chum is the grounded up body parts of fish, which means that Plankton's food is made from organs and other body parts, and this is why anyone who ever eats chum always gets sick.
  • Even if Plankton ended up selling Krabby Patties at the Chum Bucket, he could get sued by Mr. Krabs since Plankton doesn't own the right to sell Krabby Patties. This didn't happen in the first movie since Mr. Krabs was frozen and Plankton was able to forge a lie to make the public think that Mr. Krabs gave him his blessing to sell Krabby Patties at the Chum Bucket before King Neptune froze him.
  • The SpongeBob SquarePants Movie is the only film where Plankton is the main antagonist. In The SpongeBob Movie: Sponge Out of Water, he is the deuteragonist. In The SpongeBob Movie: Sponge on the Run, he is a major antagonist turned anti-hero. In Saving Bikini Bottom: The Sandy Cheeks Movie, he is a minor antagonist. In Plankton: The Movie, he is the titular main protagonist.
