"I'm ready!"

Voiced by: Tom Kenny
Debut: "Help Wanted"

An outgoing sea sponge who lives in a pineapple under the sea, as the show's Theme Tune implies. Works as a fry cook at the Krusty Krab. Although not very bright, he has a good heart and constantly strives to help his friends...even when they don't really want it.

  • The Ace: Occasionally, though generally only when he needs to make someone else jealous.
  • Achievements in Ignorance: In "House Sittin' for Sandy", he spends quite a while in Sandy's treedome without a helmet and manages not to dry up until Patrick visits and reminds him that the treedome is filled with air.
  • Adaptational Badass: In some of the Video Games.
  • Adorkable:
    • He comes off as this for his good heart and cheerful, naive personality.
    • His occasional thick-rimmed glasses and his nerdier traits (especially in the first season) like pulling out a textbook when he first sees Sandy.
    • His hobbies include bubble-blowing, jellyfishing, reading superhero comics, bedtime stories, and playing in giant cardboard boxes.
  • Alliterative Name: Spongebob Squarepants.
  • All-Loving Hero: No matter how much the others find him annoying or treat him badly, Spongebob genuinely loves everyone and everything.
  • Always Someone Better:
    • Occasionally plays this role to Squidward and once plays it for Patrick in Big Pink Loser.
    • An episode that showed off the Krusty Krab's original fry cook showed that there's someone who's even better at frying patties than him, though said original cook actually does say that Sponge could become a far better fry cook if he wised up and left the Krusty Krab to strike out on his own. Surprisingly, despite the constant Depending on the Writer of the series cast, this is a fact of Sponebob's character that almost always stays constant, even long before said episode aired.
  • Ambiguously Gay: Parents made a big controversy of his sexuality after the movie and the episode where he raises an Oyster with Patrick. The writers have since said that he's canonically asexual, though they do slip in a few lines containing some Homoerotic Subtext. It gets more and more exaggerated as the show goes on.
  • And Call Him George: His attitude towards Squidward, Mrs. Puff, Gary, Barnacle Boy... everyone in Bikini Bottom at some point or the other.
  • Annoying Laugh: Sounds like a sheep's bleating.
  • Asexual: Stephen Hillenburg plays around with this quite a bit. He mentions that Spongebob is asexual, but since actual sponges usually (though not always) reproduce by budding, he could be referring to the biological aspect only. Because there's little indication in-series that he's ever attracted to anyone, he might be asexual in orientation as well.
    • Mentions that he has a crush on Sandy could mean one of four things: he is asexual but heteroromantic note  , demisexual, biologically asexual but heterosexual in terms of orientation,'s simply Ship Tease, an accepted staple of any show.
  • Attention Deficit... Ooh, Shiny!: His attention can be limited and he's prone to distraction.
    Squidward: Attention, everyone, run for your lives! Robots have taken over the world! Our world! What do we do now?!
    Spongebob: I don't know!! ... Hey, a nickel!
    Squidward: Spongebob.
    Spongebob: ...sorry.
  • Badass Adorable: He's an Adorkable little guy who's saved the day a couple of times. And he's a master of karate.
  • Berserk Button: Don't hurt his friends; even if you're Eugene Krabs.
    • Do NOT hurt Gary, or he will hunt you down.
  • Beware the Nice/Silly Ones: He's a very kind-hearted and sweet-natured guy, but as shown in "Can You Spare a Dime", when he gets mad, he gets scary.
  • Big Guy, Little Guy: The little to Patrick's big.
  • Born Lucky: Sometimes, good things just seem to happen to him out of nowhere. Especially noticeable in comparison to Squidward.
  • Break the Cutie: Subverted in "Fools in April," played straight in "Have You Seen This Snail?" and others.
  • Bunny-Ears Lawyer: Despite his weirdness and frequent wacky antics, Spongebob is very good at his job and loves it so much that he'll gladly take any opportunity to do more work. In fact, quite few episodes have showed that SpongeBob could easily become a far more successful fry cook if he struck out on his own and focused on his own original fry cook creations, but he loves his job at the Krusty Krab too much to seriously consider it. It's one of the few facts about his character that almost always stays consistent and isn't up to Depending on the Writer, even in the later seasons.
  • Burger Fool: Subverted. He loves his job and people come from all over to eat his Krabby Patties.
  • Butt Monkey: If an episode focuses solely on Spongebob (Picture Day and Blackened Sponge, for example) something bad is almost certain to happen to him.
  • Camp Straight: Whenever he cross-dresses or has to act like a girl, he seems to enjoy it very much, as well as having a pretty girly giggle. Despite this, there have been hints that he has a crush on Sandy, a girl.
  • Captain Oblivious: Taken Up to Eleven in "A Pal for Gary," in which, even after seeing Puffy Fluffy's monstrous true form firsthand and nearly being eaten by him, he fails to notice anything amiss.
  • Catchphrase: "I'm ready!"
  • Character Title: And the main character of the show.
  • Chaste Toons: In one of the comics, he has three nephews.
  • Cloudcuckoolander: Considerably so, though Depending on the Writer, he can on rare occasions play the role of Only Sane Man.
  • Cloudcuckoolander's Minder: To Patrick. He's not the sharpest knife in the box himself, but he's certainly more level-headed than his best friend.
  • Comical Overreacting: To levels just avoiding Drama Queen.
  • Comic Trio: The Leader to Patrick's The Fool and Squidward's Only Sane Man.
  • Competition Freak: Depending on the Writer, Spongebob has a rather Serious Business attitude about games, he once became paranoid about Squidward winning Employee Of The Month, and took sandcastle building with Patrick to its most surreal.
  • Covert Pervert: If he, along with Patrick and Mr. Krabs, tries to steal panties from a woman's house in Mid-Life Crustacean is anything to go by.
  • Cuddle Bug: He loves cuddling, much to Squidward's chagrin.
  • The Cutie: Most of the time, anyway. In later seasons he's waltzing into Jerkass Ball territory more often than not.
  • Deadpan Snarker: Not as much as Squidward, but he has his moments mostly in the pre-first movie seasons.
  • Depending on the Writer: His popularity in town varies depending on the episode. In some, he's beloved by everyone for his nice guy attitude and helpful nature, while in others he's hated to the point where the town actively tries to avoid him due to how obnoxious he is. In others, nobody has any idea who he is.
  • Determinator: He may be a pushover most of the time, but nothing will stop him doing his duty for the Krusty Krab, whether it's delivering a pizza or saving his boss from execution.
  • The Dog Bites Back: To Squidward in "Can You Spare A Dime?" It doesn't last long though.
  • The Dragon: Unwitting one to Mr Krabs.
  • The Ditz: More so as the series progresses.
  • Drives Like Crazy: Probably the king of this trope in Western Animation. In early episodes, he states that he does know how to drive, but he always ends up panicking behind the wheel and cannot concentrate. Due to Flanderization, it deteriorates to the point where, whenever he gets behind the wheel, he's a Driving Disaster Area. Although in "Pizza Delivery," he drives a giant rock, and he drives a giant sandwich in the movie. Apparently he can drive anything but a boat!
  • Drill Sergeant Nasty: When training Gary for the Snail Olympics, he puts Gary through Boot Camp training. This shows he does indeed have a serious side when things get real.
  • Epic Fail: Poor guy managed to get fired five times in one day. Not mention, failing to get your boating license, even in your dreams!
  • Extreme Doormat: Has shades of this, particularly around peers such as Mr. Krabs, often making him a convenient patsy. Occasional stories show him attempt to gain abrasive skills, only to decide he is happy being "aggressively nice". And it's almost impossible for him to say no to Sandy.
  • Failure Is the Only Option: He can never get his boating license. Ever. Not even in his dreams!
  • Famed In-Story: Depending on the Writer, he is often portrayed as a local celebrity for being the Krusty Krab's frycook.
  • Flanderization: After season 3, he gravitated steadily towards the role of The Fool.
  • The Fool: Mostly in later seasons.
  • Four-Temperament Ensemble: The Sanguine.
  • Fragile Flower: He's a crybaby. He cries all the time. He even mentions in one episode that he cried for twenty minutes after stubbing his toe.
  • The Gadfly: Certain episodes imply that he will sometimes act deliberately annoying when his life is in danger, so his captors will release him- such as "Welcome to the Chum Bucket," "Spongebob Meets the Strangler," and "Born Again Krabs." He manages to drive Plankton, a serial killer, and the Flying Dutchman insane enough to allow him to escape safely.
  • Genius Ditz:
    • He can flip burgers to suit a royal palate! A running gag is that he's also great at math, and artistically inclined. If he focuses, he can be really smart.
    • In a post-movie episode, he was asked to dismantle a car and then put it back together. He ended up building a functional rocket ship. His teacher was amazed.
  • Good with Numbers: He's good at math. When Squidward asks him for change for a bill, he replies with this:
    Spongebob: Do you want four quarters? Or ten dimes? Or twenty nickels? Or one hundred pennies? Or one quarter, three dimes, seven nickels, and ten pennies? Or, if you give me a five dollar bill, your options are...
  • Healing Factor: Being a sponge, he can regenerate lost limbs. This is exemplified in an episode where he removes an arm and a new one pops up in its place. He then removes his other one, and the process repeats until he has a wall of arms holding arms. Said episode involved a scary story about a clumsy fry cook who cut off his own hand. Spongebob began repeatedly removing his arm and regrowing it to get an idea of what it was like, not seeing what was so scary about it.
    Squidward: Except he wasn't a sponge.
    Spongebob: So?
    Squidward: So it didn't grow back!
    • Strangely enough, he can even regenerate his internal organs as well. Because of this, he could theoretically be a good organ donor.
  • Heterosexual Life-Partners: With Patrick. Believes himself to be this with Squidward. He isn't.
  • Hidden Depths: He's repeatedly shown to be artistically gifted, good at math, a rather Shakespearean thespian and a talented gardener, though almost none of these traits are ever important to the plot.
  • Horrible Judge of Character: Especially with regards to Mr. Krabs. He also thinks that Squidward is a good friend of his and that Mrs. Puff is a nice teacher willing to help him, when in reality, both of them hate him to the point of insanity and want nothing more than to be rid of him.
  • Hot-Blooded: Especially when it comes to fry cooking.
  • Hyper Competent Sidekick: To Squidward, Patrick and Mr. Krabs at different times. He's constantly shown to be pretty much the only competent employee at the Krusty Krab, and is luckily incredibly dedicated.
  • Hypocritical Humor: Anytime he is forced to put up with someone as obnoxious and clingy as himself, he will become as irritable and neurotic about their lack of consideration as Squidward does about him. In one episode, he encountered a girl who looked exactly like him and he referred to her as "ugly" behind her back.
  • Idiot Hero: One of Western Animation's most iconic examples. Although in the earlier seasons he was more of a naive Cloud Cuckoolander than an Idiot Hero.
  • Idiot Houdini: To the point when he gets away with making Squidward and Mrs. Puff's lives a living hell. An example being in a short that involves Mrs. Puff trying to cover "Boat Smarts". Being the reckless driver he is, Spongebob causes a crash, and a big accident on the road. Instead of apologizing or feeling bad, he chastises Squidward and Mrs. Puff, claims they forgot their boat smarts, and drives off laughing without punishment.
  • Incorruptible Pure Pureness: Simply injecting himself with DNA from one of Spongebob's tears was enough to make Plankton pull a Heel-Face Turn, and his heart is so pure that he's immune to jerktonium (a chemical which turns people into jerks.)
  • Innocent Blue Eyes: He has an innocence about him.
  • Innocently Insensitive: All though SpongeBob means well, he unintentionally ruins other peoples' lives. Just ask Squidward or his boating school teacher Mrs. Puff. At worst, his behavior can also cross under Unsympathetic Comedy Protagonist territory.
  • In Touch with His Feminine Side: He wears his heart on his sleeve, cries openly and very often, has some effeminate mannerisms, and has been shown wearing women's clothing several times. There's also the fact that he apparently owns a lot of women's clothing and make-up in the first place. Patrick mocks him for this in "I'm With Stupid," saying, "Do you have any mascara I could borrow?"
  • Jerkass Ball: Not as much as other unpleasant characters in the show, but he still has his moments throughout the series (especially evident during the post-movie seasons).
    • In "Choir Boys", he seems to be tormenting Squidward deliberately and reveling in his misfortune.
    • In "A Pal For Gary", he acted like an insensitive jerk to Gary, even after Gary saved his ungrateful life.
    • He reaches a new level in "Demolition Doofus". While his injuring Mrs. Puff was an accident, he showed absolutely no remorse whatsoever for his actions, and makes jokes about her situation instead of apologizing. Mrs. Puff, however, wasn't any better during this incident however.
  • Jerk with a Heart of Gold: In later seasons, due to his Flanderization. While he's more prone to insensitivity and can even have a mean streak at times, he's still an optimistic Nice Guy who really means well at the end.
  • Kindhearted Simpleton: The large majority of times. He at least means well, anyway.
  • Kindhearted Snail Lover: His pet snail, Gary.
  • The Kirk: More rational than Patrick; still not as level-headed as Squidward or even Mr. Krabs.
  • Large Ham: One has to assume that Spongebob's taken drama lessons at some point or another, because overdramatizing is his specialty. He can be more reserved when he wants to be, but it's usually hard for him to go a full episode without lapsing into this at some point.
  • Lethally Stupid: His relentless stupidity has driven many people (mainly Squidward and Mrs.Puff) borderline, if not completely, insane.
  • Made of Iron: Depends on the episode. Spongebob can take a lot of pain, and he just shrugs it off or regenerates.
  • Man Child: He's old enough to hold down a job and live on his own, but is so immature and goofy that he's been referred to as a kid on multiple occasions.
  • Married to the Job: He's very devoted to his job at the Krusty Krab.
  • Masculine Girl, Feminine Boy: Feminine Boy to Sandy's Masculine Girl.
  • Me's a Crowd: Sometimes after being cut into pieces, those pieces form miniature Spongebobs.
  • Minion with an F in Evil: To Mr. Krabs sometimes, and in the episode "Welcome to the Chum Bucket" to Plankton.
  • Motor Mouth: Tends to talk really fast and rapidly when he's very excited, much to the annoyance of other people.
  • Mr. Imagination: He provides the page quote. Another example (though it doesn't spell it out as clearly) is an episode where Spongebob manages to have lots of fun with only a piece of paper Squidward discarded. When Squidward tries, he can't do any of the things with the piece of paper Spongebob did, probably because he has no imagination.
  • Mundane Made Awesome: In "Procrastination", when writing an essay, he makes the pencil fall like a toppling airplane against the sheet of paper and begins writing rapidly while shouting "Yeah!" When he's finished, he lets go of the pencil which fumes from the use of it, then it turns out he just wrote "The" in a very artistic way.
  • Neat Freak: In contrast to his friend Patrick.
  • Nice Guy: Almost absurdly nice, on a good day: he's a borderline doormat sometimes. Most of the time.
  • Nice Mean And In Between: He's so nice it hurts. Most of the time.
  • Nigh-Invulnerability: He seems to be practically impossible to kill at times (he can regrow internal organs). In fact, only when he suffers from a very painful situation such as launching himself onto an island made of spikes or being caught in the demolition of a high tower does he not regenerate near-instantly from his injuries.
  • No Indoor Voice: Whenever he gets excited or hyped up about something.
  • No Sense of Personal Space: As Squidward says in one episode: "Spongebob, do you remember that little talk we had about personal space?"
  • No Social Skills: Frequently laps into this territory.
  • Nosy Neighbor: Towards Squidward (see above).
  • Older Than They Look: He's a grown adult in his twenties (his driver's license, when seen, says he was born on July 14th, 1986) but with his freckled dimpled cheeks, high-pitched voice, big blue eyes, naive demeanor, long eyelashes, and short stature, he easily passes for an actual child.
  • Obliviously Evil: Not technically "evil," but he fails to realize the hell he puts Squidward through.
  • Obfuscating Stupidity: Several episodes do show him acting serious and even competent, suggesting that he can choose to be smart anytime he wants.
  • One-Note Cook: Spongebob can make excellent Krabby Patties, sometimes it's the only thing he can make. He doesn't even know what a "salad" is in an early episode and the concept of just lettuce and tomato shocked him.
  • The One Who Wears Shoes: With the exception of Sandy, and even then, she takes them off in her Treedome. In one early episode, it's implied he's been wearing shoes since before he was born.
  • Papa Wolf: To Gary, his pet snail. Also shows up when he's left to care for a bunch of baby worms.
  • Ping-Pong Naïveté: Is capable of surprising bouts of resourcefulness and wisdom and can even play the Straight Man on occasion, but can never figure out that half the town wants him to leave them alone.
  • The Pollyanna: He's always cheerful and positive, no matter what.
  • The Power of Rock: Crowning Moment of Awesome in The Movie, along with episodes like "Ripped Pants," "Band Geeks," and "Hello Bikini Bottom."
  • The Protagonist: The main character of the show.
  • Punch Clock Villain: Played With, he willingly works for Mr. Krabs, or rather, just the job itself, but he only occasionally does malicious things. Such as not actually killing a health inspector, or feeding people spoiled food.
  • Red Oni, Blue Oni: The red to Squidward's blue.
  • Ridiculously Cute Critter: Just look at him!
  • Rubber Man: He can stretch his limbs towards great lengths & put himself together after being cut into pieces.
  • Sarcasm-Blind: Whenever Squidward delivers sarcastic remarks at him, he never seems to notice.
  • Selective Obliviousness: He just cannot seem to comprehend the obvious fact that not only is Squidward not his best friend, but in fact hates him to the point of madness. Even though Squidward has flat-out told SpongeBob to his face that he can't stand him on at least one occasion.
  • Serious Business: He once cried because he arrived at the Krusty Krab one minute late.
  • Ship Tease: There's a lot with Sandy, for example whenever they're at the beach, his attempts to impress her are usually what create the plot.
  • Sickly Neurotic Geek: He has the tendency to start wheezing loudly when he gets too excited about something. Krabs also implied in one episode that he takes allergy medication.
  • Signature Laugh: It's annoying, but so much a part of his character that it alone is enough for one to recognize him.
  • Small Annoying Creature: Especially if you ask Squidward.
  • Small Name, Big Ego: Depending on the Writer.
  • Small Taxonomy Pools: Why he was made a sponge, an animal rarely mentioned in media.
  • Strong as They Need to Be: Spongebob's strength varies from episode to episode. Some episodes depict him as so weak he couldn't even lift a straw, other depict him lifting a mailbox straight off its hinges. This also applies to his skills in karate; at times he can fight Sandy evenly or even beat her with ease, while at other times he's incompetent to the point where Sandy literally kicks him around like a football.
  • The Southpaw: He is said to be left-handed or ambidextrous, some episodes you can see him using his left hand to flip patties. In "I Was A Teenage Gary," he says that he's a leftie, but he claims to be ambidextrous in "You Don't Know Sponge." He probably has a preference for his left hand.
  • Speaks Fluent Animal: Can understand snails.
  • Species Forename: Part of his full forename.
  • Sphere Eyes: He has them.
  • Stalker Without A Crush: On Squidward.
  • Stepford Smiler: Some episodes imply that he's one.
  • Stone Wall: Depicted as one in "The Bully," where he took punches to the head for an entire week without any damage, until his assailant passed out from exhaustion. Of course, another episode stated that he cried for 20 minutes after stubbing his toe, so this largely depends on Rule of Funny.
  • Super Speed: As the Quickster in "Mermaid Man and Barnacle Boy V".
  • Tender Tears: He cries when bad things happen to other people. At one point, he got tearful when he saw a snail stuck in a tree.
  • Too Dumb to Live: At his worst.
  • Took a Level in Dumbass: When the series began he was fairly intelligent but incredibly naive and childlike; in the later episodes he is barely smarter than pre-first movie Patrick. In any case, Patrick still makes him look like a genius by comparison.
  • Took a Level in Jerkass: In later seasons, see Unsympathetic Comedy Protagonist.
  • Truly Single Parent: Spongebob, like real sponges, displayed the capacity for asexual reproduction in "Pressure", though the new Spongebobs were gone by the next scene.
  • Turn the Other Cheek: Case in point: no matter how heinous Mr. Krabs' actions are or how badly he is treated, SpongeBob will always forgive him by the end of the episode.
  • Undying Loyalty: His unbreakable dedication to the Krusty Krab and by extension Mr. Krabs surpasses even his loyalty to his friends.
  • Ungrateful Bastard: In "A Pal For Gary". Throughout the whole episode, he has blamed Gary for Puffy Fluffy's actions, cumulating in scolding Gary when the snail is clearly about to be eaten by the now-monstrous Puffy Fluffy. Puffy puts Gary down and starts eating Spongebob, and Gary (who has NO REASON WHATSOEVER to help Spongebob, at this point) bravely comes to the rescue, acting like a cowboy and whipping Puffy to knock Spongebob out of his mouth and drive him away. How does Spongebob reward this act of heroism? He tries to get Puffy Fluffy back, but after that fails, he scolds Gary AGAIN, completely ignoring the fact that the snail just saved his ungrateful life!
  • Unsympathetic Comedy Protagonist: Zigzagged. His behavior can sometimes go beyond Innocently Insensitive. Sometimes in episodes when he pesters and causes pain to the other characters (Boat Smarts, Good Neighbors, A Pal For Gary, etc), and we're supposed to root for him.
  • Vague Age: Subverted, in a dream when he got his driver's licence it has the birth date July 12th 1986, meaning Spongebob is 28. Though, that doesn't really explain how he has over 300 employee of the month awards or how he failed the drivers test over one million times.
  • Vocal Evolution: His voice has gotten a lot higher in later episodes. But his voice has gotten lower in Season 9 and especially Sponge out of Water.
  • Why Did It Have To Be Clowns?: Apparently, Spongebob is seriously afraid of clowns, as the only reason he summoned all of Bikini Bottom to his Pineapple in the episode "Rodeo Daze" was to save Sandy from the clowns at the rodeo.
  • Wide-Eyed Idealist: Luckily for him, though, his idealism usually makes things work out for him.
  • Workaholic: At one point, Mr. Krabs's forcing him to take a vacation nearly caused him to go insane. In "The Splinter," he frantically tries to avoid being sent home early. In "Suds," he drags himself to work, despite being so sick that he can barely stand or keep his eyes open and he's sneezing constantly. Despite insisting that he is okay (punctuated by a loud sneeze,) Mr Krabs sends the guy home so he can rest. This exchange from "Graveyard Shift" says it all:
    Mr. Krabs: From now on the Krusty Krab is open 24 hours a day.
    Squidward: What...!
    Spongebob: Wooow! Now we never have to stop working!
  • Yes-Man: While he occasionally plays an ignored voice of reason to Mr. Krabs, he generally goes with whatever he says without raising a finger.

    Patrick Star 
Voiced by: Bill Fagerbakke
Debut: "Help Wanted"

A not-quite-bright starfish and Spongebob's best friend.

  • Accidental Truth: In the episode "Patrick-Man!", he started attacking patrons at the Krusty Krab, believing that one of them was a supervillain in disguise. When Mr. Krabs is about to throw him out, it turns out that the Dirty Bubble was in fact there in disguise.
  • Acquired Situational Narcissism: All the freakin' time.
  • Acrofatic: He's pretty quick and nimble for a fat guy, though, it depends.
  • Adipose Rex: In "Rule of Dumb".
  • Adorkable: In earlier seasons.
  • All Take and No Give: As shown in "Yours, Mine, and Mine," in Patrick's eyes, sharing amounts to SpongeBob paying for such things as food and toys and Patrick getting them all to himself.
  • Ambiguous Disorder: There's often the implication that Patrick has genuine mental problems in addition to just being extremely stupid. Just see Ax-Crazy below.
  • Attention Deficit... Ooh, Shiny!: Played With, sometimes he's easily distracted, and sometimes nothing distracts him.
  • Attractive Bent-Gender: When he's disguised as Patricia in "That's No Lady", every male in Bikini Bottom is attracted to him.
  • Ax-Crazy: In "Valentine's Day" and "Nature Pants".
  • Believing Their Own Lies: In "I'm With Stupid," he made a plan with SpongeBob to have SpongeBob pretend to be stupid for Patrick's parents so Patrick would look smarter by comparison. Somewhere along the way, he began to think that SpongeBob really was stupid and that he himself was a genius.
  • Berserk Button: In the first three seasons, Patrick would go a rampage if anything greatly upset him. Examples include being the only person who didn't get a gift from Spongebob on Valentine's Day, Spongebob living with the jellyfish, and being called "Tubby" or "Rick".
  • Beware the Silly Ones: Seriously, he can go from being delightfully silly one moment to being an Ax-Crazy psycho the next.
  • Big Guy, Little Guy: The big to Spongebob's little.
  • Big Eater: Throughout the series.
  • Big Fun: Patrick is a funny, lovable fat guy.
  • The Big Guy: Fits all the criteria.
  • Bumbling Sidekick: And considering whose sidekick he is, it's an accomplishment.
  • Butt Monkey: At times.
  • Childhood Brain Damage: It is often suggested that Patrick's stupidity is the result of frequent head injuries. In "Squidward the Unfriendly Ghost", Patrick mentions that he knows a lot about head injuries, then spaces out mid sentence. In "Big Pink Loser", Spongebob tries to discourage Patrick from mimicking him by hitting himself with a hammer, to which Patrick responds, "I've been doing this way before I started copying you."
  • Comic Trio: The Fool to SpongeBob's The Leader and Squidward's Only Sane Man.
  • Covert Pervert: If he, along with Spongebob and Mr. Krabs, tries to steal panties from a woman's house in Mid-Life Crustacean is anything to go by.
  • Dangerously Genre Savvy: For an idiot, Patrick may come off as this sometimes, mostly during some of his antagonistic roles.
  • Deadpan Snarker: In the earlier episodes, and occasionally the later ones, but not as frequently.
  • Despotism Justifies the Means: In "Rule of Dumb," when he becomes the king of Bikini Bottom, he becomes a ruthless despot who believes he has the right to take and do whatever he wants.
  • Destructive Savior: In the episode "Patrick-Man!", he tries to fight the Dirty Bubble, but in the process he completely destroys the Krusty Krab and only defeats the Bubble through sheer dumb luck.
  • Deuteragonist: In The Movie, with Spongebob as The Protagonist.
  • Diabolus ex Machina: Occasionally starting in season 7.
  • Disguised in Drag: When he thought a salesman was threatening his life, he, with Spongebob's help, disguised himself as a girl named Patricia. Cue every other male in Bikini Bottom (especially Squidward and Mr. Krabs) falling for him.
  • The Ditz: He makes Spongebob look intelligent.
  • Dumbass Has a Point: Occasionally.
    • One such instance has him beating out Sandy in coming up with a plan.
    • In earlier episodes, Patrick tended to be the one to suggest that Squidward didn't like him and Spongebob. Spongebob, naturally found such a notion unthinkable.
    • Played with in "Wet Painters". After SpongeBob panics over getting paint on Mr. Krabs' first dollar (he was warned not to get paint on it), Patrick Star points out that Mr. Krabs' first dollar doesn't look any different from a normal dollar and could easily be replaced with any old dollar without Mr. Krabs knowing. The way this is played with is that Patrick immediately uses the dollar SpongeBob asked him to use on a vending machine instead of replacing the dollar that got covered in paint.
  • Dumb Muscle: He has been shown on a few occasions to be fairly strong, though this is especially prominent in the games.
  • Evil Counterpart: To Spongebob in "The Fry Cook Games".
  • Exposed Animal Bellybutton: He provides the trope's page image.
  • Fat Bastard: At his worst, mostly in later episodes.
  • Fat Best Friend: To Spongebob.
  • Fat Idiot: Fat? Check. Idiot? Check.
  • Fat Slob: If "The Battle of Bikini Bottom" is to be believed.
  • Flanderization: Patrick started out quite dim, however as the series progressed Patrick became dumber and dumber until it became the vehicle for all his appearances.
  • The Fool: Along with Spongebob.
  • Four-Temperament Ensemble: The Phlegmatic.
  • Genius Ditz: He has his moments of brilliance. In at least one boating episode, he was shown to be perfectly accurate behind the wheel, as he could give perfect instructions to Spongebob simply via a large telescope, sometimes while barely paying attention, and in another episode, he even GOT a boating license despite not knowing everything there is to know about boats.
  • Half-Dressed Cartoon Animal: Only wears a pair of shorts.
  • Heterosexual Life-Partners: With Spongebob.
  • Healing Factor: He can regenerate his arms in the unlikely case that they get severed.
  • Innocently Insensitive: Like SpongeBob, he can often be simply oblivious to and ignorant of how his behavior affects others. At times, the "innocent" part gets a little dubious.
  • Idiot Houdini and Karma Houdini: Often gets away with the things he screws up. The most notable moment is in I'm With Stupid, when he lets Spongebob pretend he was stupid to impress his parents, but then he went too far and actually believed Spongebob really WAS stupid. This causes the sponge to run off in a rage...and Patrick gets away with it.
  • Informed Attractiveness: When Patrick crossdresses in "That's no Lady" as a means to hide his identity, he's considered a true feminine beauty by all males in Bikini Bottom (oblivious that he's Patrick). The thing is, he really doesn't look that different from his usual self; only adding pigtails, lipstick and a dress.
  • Jerkass: On occasion, though as usual this was emphasized more due to Flanderization in later episodes.
  • Jerk with a Heart of Gold: When he's not being a jerk, he still can be a well-meaning idiot and a good friend to Spongebob.
  • Kindhearted Simpleton: Mostly in the pre-movie seasons.
  • Lack of Empathy: At his worst (at his best he's just too dumb to know any better). It's another case of Depending on the Writer, in some cases he just blows off any pain or anguish he causes, in others he can be brought to tearful remorse for stealing a donut that is actually his gift.
  • The Lancer: To Spongebob's The Hero.
  • Large Ham: Moreso in earlier episodes, but still somewhat in later ones.
  • Lazy Bum: In contrast to the hard-working Spongebob.
  • Lethally Stupid: Whenever he shows up in newer episodes, it's almost guaranteed everything will go horribly wrong.
  • Love Hungry: See Ax-Crazy above; he has a tendency to react badly when under the impression that his friendship with SpongeBob is in jeopardy.
  • Made of Iron: Just like Spongebob, there isn't alot of things in the series that can put him in the hospital.
  • The McCoy: With Squidward as The Spock and Spongebob as The Kirk.
  • Man Child: Patrick is an adult and he's almost as childish as Spongebob, if not more.
  • Manipulative Bastard: This is often how Spongebob goes along in one of his schemes. An example would be the episode in which Squidward accidentally swallowed his reed. Spongebob was told to watch the submarine, and Patrick asked him if he looked after it from the inside as well.
  • The Millstone: Whenever SpongeBob or anyone has a plan, Patrick is sure to screw it up, or do something stupid to make it worse.
  • Neet: Does not have a job.
  • Nice Mean And In Between: The in-between, at least in earlier seasons, where he wasn't as overly affectionate as SpongeBob but also wasn't as snide as Squidward. Later seasons, however, and even some earlier episodes, show that Patrick can be plenty mean in his own right.
  • The Noseless: He doesn't have a visible nose, though he's been portrayed as having nostrils on occasion.
  • Obfuscating Stupidity: Possibly. Some people suspect that Patrick is not really stupid, but a sociopath who does stupid and often assholish things on purpose just because he knows his low intelligence (or facade of it) will keep him from punishment. In "The Card" he even says "You can't always expect my usual brand of stupidity. I like to mix it up. Keep you on your toes."
  • Parental Neglect: In "Rock a Bye Bivalve," he repeatedly refuses to help the baby scallop. Though that in his eyes seems to be a traditional father figure.
  • Poisonous Friend:
    • Patrick was willing to assault Spongebob's kindly grandmother to keep him from being teased by others.
    • An episode called Ghoul Fools showed that Patrick was willing to sacrifice Spongebob because he "lived a full life." This was actually lampshaded by Lord Poltergeist, who says sarcastically "Great friend you got there."
  • Psychopathic Manchild: During his more villainous roles. For example, in "Valentine's Day," he threw a destructive temper tantrum when he believed that SpongeBob hadn't given him an actual Valentine's Day gift.
  • Ridiculously Cute Critter: Less so than Spongebob, but he's still chubby, pink, and cute-looking. He also has purple eyelids and flowered swimming trunks.
  • Rubber Man: As the Elastic Waistband in "Mermaid Man and Barnacle Boy V".
  • Simpleton Voice: Even his voice sounds stupid.
  • Snark Ball: Often.
  • Species Surname: Patrick Star is a starfish.
  • Stock Sound Effects: His Big Eater moments are often punctuated by the sound of a Hoover vacuum cleaner.
  • Stout Strength: He's overweight but still quite strong.
  • Straw Loser: Spongebob is a often a brainless irritance to others, when paired alongside the even dumber Patrick however, he can often come off as vaguely competent and level headed.
  • Strong as They Need to Be: Typically, he's strong enough to lift and throw things as heavy as a Dumpster with ease, but in "Krusty Krushers," he couldn't even tear a piece of paper in half and got a paper cut trying to do so.
  • Super Strength: At times, he is able to throw boulders as if they were pebbles & break through steel walls. On at least one occasion, he actually managed to overpower Sandy.
  • Sweet Tooth: Because he is a starfish, he loves to eat ice cream and many other junk foods.
  • Temporarily a Villain: At his worst.
  • Too Dumb to Live: At times, like when he forgets how to breathe.
  • Too Incompetent to Operate a Blanket: In "Big Pink Loser," he's shown needing to actually be talked through the simplest tasks, such as sweeping floors or opening jars.
  • Took a Level in Dumbass: He becomes much dumber in later seasons.
  • Took a Level in Jerkass: Even more so than Spongebob. The prime example? The episode "Rule Of Dumb".
  • Unsympathetic Comedy Protagonist: In post-season episodes, Depending on the Writer.
  • Vague Age: He's apparently old enough to live on his own and have a job, but is childish to the point where everyone, including himself, refers to him as a kid. However, there are several episodes where Spongebob proves that he is capable of acting his age. And unlike Spongebob, his driver's license never revealed his date of birth, though it's assumed that he's around his late 20's like Spongebob is.
  • Vocal Evolution: His voice has gotten quite a lot deeper in later episodes. Almost to a creepy extent, he used to sound like a goofball, and now he sounds a tad thuggish.
  • Walking Shirtless Scene: Fan Disservice.
  • Why Did It Have to Be Snakes?: In one episode, he starts smashing Spongebob with his house in his sleep, screaming "SPIDERRRS!"
  • Would Hurt a Child: When Spongebob teaches him karate he uses it to go around town destroying property, and attempts to kill a baby until Spongebob stops him.

    Squidward Quincy Tentacles 
"How did I ever get surrounded by such loser neighbors?"
Voiced by: Rodger Bumpass
Debut: "Help Wanted"

A cranky perfectionist octopus. Works as a cashier at the Krusty Krab, and is Spongebob and Patrick's neighbor, much to his chagrin.

  • Accidental Truth: In "Funny Pants," after getting annoyed by Spongebob's non-stop laughing to a joke, Squidward tells him that if he doesn't give it a break, he'll blow out his "laugh box" and never be able to laugh again. In the end, he reveals the trick to Spongebob and laughs over it, finding out the hard way that laugh boxes are real.
  • All of the Other Reindeer: Hated, avoided, mistreated, and sometimes even assaulted by people in Bikini Bottom, sometimes for no reason.
  • Amazing Technicolor Wildlife: Double Subverted, some squids and octopi look blue, but it's often because of water tint. Subverted in "Reef Blower", where he turns purple above (well, without) water. Double subverted for the other times he's been above water.
  • Animals Hate Him: At times. SpongeBob even implies in "The Thing" that Gary actually attacks him.
  • Annoying Laugh: A very honky sounding one due to his nose.
  • Anti-Hero: At best.
  • Anti-Villain: Depending on the Writer
  • Attention Whore: To ridiculous levels.
  • Born Unlucky: Nothing ever goes right for him; he is injured, humiliated and/or driven insane almost every episode.
  • Break the Haughty: Often happens to him. The most subtle example must be the episode in which Squidward tries moving to a town of inhabitants who are just like him...only to end up so bored that he flips out. Naturally, the town haughtily expels him.
  • Brilliant but Lazy: It is implied that Squidward would have genuine talent if he wasn't completely sapped of any passion. In "A Breath Of Fresh Squidward" an electric shock alters Squidward's brain and makes him as devoted and high spirited an employee as Spongebob, and actually ruins Spongebob's Employee Of The Month winning streak. Similarly Squidward often goes from a hack to a somewhat plausible musician when in a satisfactory mood.
    • It's also shown that he has a decent talent in different art styles, and he could make a name for himself with these if it weren't for the fact that they're all of him. Also there's his Butt Monkey and Chew Toy status, especially in later episodes.
    • He also has unusual skills, like being a surprisingly good construction worker. In one episode he rebuilds Spongebob's entire house.
  • Bullying a Dragon: In the campfire episode, Squidward does all the things that Spongebob and Patrick told him not to do to attract a sear bear. The sea bear arrives. It does not end well for Squidward.
  • Burger Fool: You can literally see his dreams of being an artist die in his eyes in each episode.
  • Butt Monkey: He almost always on the butt end of the Amusing Injuries stick.
  • Camp: Into fancy towel robes, flowers, tea, painting, and playing clarinet, he's definitely got this going for him.
  • Cannot Tell a Joke: He can tell a joke, but his monotonous deadpan tone makes it not really work.
  • Can't Stand Them, Can't Live Without Them: In "Squidsville", towards Spongebob.
  • Cartoon Creature: There's squids, there's octopi and then there's... his species. Word of God says he's an octopus (though with the number of tentacles a squid has), but the name "Octoward" wasn't near as good.
  • Catch Phrase:
    • "I can't believe I'm saying this/never thought I'd say this, but..."
    • His little tune of "La da dee, la da do, la da dum" in the post-film series.
  • The Chew Toy: Subverted, he's widely considered to be the most sympathetic character on the show and many people just want to see him succeed once.
  • The Comically Serious: Having a rather serious person in the wonderfully wacky world of this show can be funny, though with how sociopathic the Spongebob world has become it loses its humor.
  • Comic Trio: The Only Sane Man to SpongeBob's The Leader and Patrick's The Fool.
  • Cosmic Plaything: The whole universe seems to be against Squidward, as there are several episodes dedicated to making him suffer in various ways.
  • Cranky Neighbor: Justified, living next-door to a guy who won't leave you alone can drive a man to this.
  • Deadpan Snarker: BIG TIME.
  • Depending on the Writer:
    • He can very between being a sympathetic Chew Toy to an outright Jerkass, the latter being his prominent characterization in the pre-movie seasons.
    • Just how sympathetic Squidward is depends on the writer. In the first three seasons, he was just an intolerant grouch; for example, in the first season episode "Naughty Nautical Neighbors," he discreetly ruins Spongebob and Patrick's friendship simply because their talking via bubble-blowing annoyed him. In later seasons, he jumps between intolerant jerk and sympathetic chew toy. It's taken Up to Eleven in "Sponge-Cano!", where he is openly and completely rude, hostile, and disrespectful to everyone and everything he comes in contact with and declares himself to be the most miserable person in Bikini Bottom. And in "Little Yellow Book" where he shows an extreme Lack of Empathy towards Spongebob's feelings when reading his diary.
  • Dirty Coward: When things are looking bad, he'll just run away. Though, it's hard not to sympathize with how messed up the world around him is.
  • Disproportionate Retribution: In "Fools in April," he gets irritated with SpongeBob pulling April Fools pranks on people and pulls one of his own on him. Of course, SpongeBob's pranks were playful and completely harmless, like putting one ice cube in a customer's drink when said customer asked for a couple, while Squidward's prank was physically painful and just plain cruel. He realizes this only after the damage is done.
  • Doesn't Like Being Touched: Especially when Spongebob does it.
  • Dreadful Musician: Squidward loves his clarinet. But it doesn't seem to love him. Although in some episodes, he's decent, even actually pretty good.
  • Dub Name Change:
    • Called "Ikardo Tentacles" in Japanese, with "ika" being the Japanese for "squid".
    • The German dub calls him "Thaddäus Tentakel". His friends call him Thaddel.
    • He is called "Lula Molusco" in Brazil.
    • In Spain he is called "Calamardo Tentaculos".
    • In Finland he's called "Jalmari Kalmari". His nickname is "Jammu".
    • He is called "Kalmer" in Estonia.
    • He is called "Bläckvard Tentakel" in Sweden.
  • The Eeyore: Downplayed in earlier episodes where he still had some hope of success, but played up more in later episodes to a rather depressing degree.
  • Enemy to All Living Things: His plants aren't that fond of him either.
  • Enraged by Idiocy: With how stupid Spongebob and Patrick have become, it's fairly easy to understand.
  • Even Evil Has Standards: Although not really evil, Squidward is a notorious Jerkass who hates SpongeBob with a passion. Even so, he was absolutely disgusted when Mr. Krabs sold SpongeBob's soul to the Flying Dutchman for pocket change.
  • Everything's Squishier with Cephalopods: He's an octopus... with six tentacles.
  • Exotic Eye Designs: He has rectangular red pupils.
  • Expy: Word of God once commented that Squidward was the "Mr. Wilson of the show."
  • The Finicky One: Big time, bigger time in the later episodes.
  • Flanderization:
    • In many of the newer episodes, his Butt Monkey status has become flat out Disproportionate Retribution.
    • He's become less grouchy and more openly hostile, sometimes even physically attacking Spongebob.
  • Foil: He's just about the closest you can get to an anti-[Spongebob].
  • Forgot Flanders Could Do That: Does occasionally get the chance to display some actual musical or other talent. He was, in fact, initially characterized by Plankton as a "mediocre clarinet player," but has usually been shown as an abysmal one.
  • Four-Temperament Ensemble: The Melancholic.
  • Freudian Excuse: Suffered a miserable childhood and lives with neighbors who harass him everyday.
  • Giftedly Bad: Subverted, he can play the clarinet, or at least it's implied, but stress and loss of passion make him terrible at it.
  • Green-Eyed Monster: Happens whenever someone else that has artistic talent shows up, especially Squilliam.
  • Grumpy Bear: Oh God, yes.
  • Hair-Trigger Temper: Early on, Squidward would be upset by Spongebob and Patrick playing dumb games with each other. Downplayed later, then brought back again, even worse than before.
  • Half-Dressed Cartoon Animal: Only wears a shirt.
  • Hates Being Touched: Sadly for him, Spongebob loves cuddling.
  • Heterosexual Life-Partners: Subverted. Spongebob believes that they're this. To his credit, Squidward occasionally almost reciprocates.
  • Hollywood Atheist: "Just One More Bite" implies that Squidward is either an atheist or a Nay-Theist, with him remarking to Spongebob that he "Has no soul" (a hellish background and laugh pops up behind him when he says that, and he notices, so make of that what you will).
  • Human Popsicle: During the events of "SB-129", Squidward is locked in the freezer. He thinks someone will notice he's gone and get him out. They do not after 2,000 years, where Squidward travels back to his normal time. So technically, he's over 2,000 years old.
  • Informed Species: Word of God is he's a octopus.
  • Iron Butt Monkey: Thankfully, like Spongebob, he's pretty much near indestructible. Being exploded, run over, hit with doors, having his toenail ripped off and being gored multiple times he's still alive.
  • It's All About Me: Played With, sometimes he is a selfish jerk, and other times his heart of gold pulls through.
  • Jerkass: For the most part, he completely despises SpongeBob and Patrick and doesn't even bother trying to hide it... not that they ever understand.
  • Jerkass Has a Point: Some of his anger towards Spongebob is often understandable for obvious reasons.
  • Jerk with a Heart of Gold: Sometimes sympathetic towards Spongebob.
  • Lack of Empathy: Taken Up to Eleven in "Little Yellow Book"
  • The Lancer: To Mr. Krabs in the earlier seasons, though it didn't save him from old man Krabs' schemes to get money. Case in point, he's appointed manager of the Krusty Krab 2 in the movie, and left in charge a few times while Mr. Krabs is away or in the hospital (or in one case dead). Occasionally plays Spongebob's nay-saying foil when tagging along on adventures.
  • Laser-Guided Karma: His horrific luck was intially presented as this to his jerkass attitude. As the show evolved however, his Butt Monkey role became less provoked and leaned more into Comedic Sociopathy territory.
  • Lazy Bum: Common theme of the Krusty Krab episodes is that Squidward often dumps his workload on Spongebob. Since the latter is easily manipulated and very much a workaholic, he takes the extra work without a second thought.
  • Lean and Mean: Sometimes.
  • Lethal Chef:
    • The krabby patty he made in "The Algae is Always Greener" deserves special mention.
    • And this priceless little snippet:
    Customer #1: You call this food!? My sandwich tastes like a fried boot!
    Customer #2: My sandwich is a fried boot!
    • This:
    Customer #1: He burnt my Krabby Patty.
    Customer #2: He burnt my fries!
    Customer #3: He burnt my shake.
    • However, he's quite good at conventional baking, such as casseroles and soufflés.
  • Magma Man: As Captain Magma in "Mermaid Man and Barnacle Boy V".
  • Narcissist: Just about all of his artwork is self-portraits.
  • Nice Mean And In Between: In earlier seasons, Squidward was clearly meant to be the mean one in comparison to SpongeBob and Patrick, rejecting their friendly overtures and sometimes even trying to drive them apart.
  • Never My Fault: In earlier episodes, though now it really has become not his fault.
  • Non-Action Guy: Never shown doing the cartoonish feats of athleticism the rest of the cast are and generally seems to be pretty unathletic.
  • No Respect Guy: One episode revolves around Spongebob thinking Squidward has died and is now haunting him. When he arranges a funeral for him, the guests have this to say:
    Mr. Krabs: Oh, Squidward... we all came as soon as we were sure you were dead.
  • Non-Indicative Name: Word of God has it he's not a squid, but an octopus.
  • Nonstandard Character Design: Many characters are made to look cute, or at least marketable. Squidward is less so.
  • Not So Above It All: If Squidward does partake in Spongebob's tomfoolery, he'll end up taking the games too seriously, ruining them for everyone else.
  • Only Sane Man: This doesn't make him any better, however.
  • Perpetual Frowner: With how poorly he's treated, it's understandable.
  • Pet the Dog: Sometimes shows compassion for others. "Pizza Delivery" is the most obvious where a fish crushes SpongeBob's spirit for no good reason and Squidward gets ticked off and shoves the pizza down the offender's throat. Interestingly, episodes like this downplay his Butt Monkey status considerably.
  • Psychopathic Manchild: While he's serious most of the time, a few episodes such as Fools In April have him acting childish, and becoming a dangerous madman in the process.
  • Red Baron: As the Killer Krabby Patty in Spongebob, You're Fired!
  • Red Eyes, Take Warning: When he gets really angry.
  • Red Oni, Blue Oni: The blue to SpongeBob's red.
  • Shaking the Rump: Does this on occasions, especially when mocking Spongebob in "Club Spongebob".
  • Small Name, Big Ego: Just to give you an idea — all of Squidward's art projects are self-portraits. Believes himself to be a wonderful artist when in reality he's not, sometimes.
  • The Snark Knight: Always snarky and always making comments on the screwed up world around him.
  • The Spock: Much much more so in the later episodes where he seems to be the only person with a level head.
  • Stepford Snarker: Implied a lot, all he wants is to not be mistreated and get some appreciation for all the work he does, but the world around him keeps messing with him.
  • Straw Loser: Let's face it, it takes one Butt Monkey to make the likes of SpongeBob and Patrick look like winners.
  • Surrounded by Idiots: The only characters he doesn't have a problem with are Sandy and Pearl.
  • Super Strength: Shown in "Patty Caper", where he literally lifts & moves his own house. Otherwise subverted.
  • Temporarily a Villain: While villain may be a strong word to describe him, he played this role whenever he falls into the Took a Level in Jerkass territory.
  • This Loser Is You: Probably the most Closer to Earth character in the show, though despite his superior logic and sanity over the rest of the cast, he is often depicted as a Small Name, Big Ego who is talentless and unexceptional in reality.
  • Those Two Guys: With Mr. Krabs, especially in earlier seasons as they're both adults compared to Spongebob and Patrick.
  • Throw the Dog a Bone: Gets one roughly Once a Season. Either something finally goes right for him, or he at least gets to laugh at karma finally hitting Spongebob.
  • Took a Level in Badass: Beat the tar out of a group of greedy fast-food proprietors who were trying to use SpongeBob for slave labor while dressed in a giant Krabby Patty suit. Also functions as a Big Damn Hero moment.
  • Took a Level in Jerkass: In seasons 1-3, Squidward acts like a jerk towards Spongebob and Patrick most of the time, but at some points can be shown to actually care about them. In later seasons he takes the first possible opportunity to Kick The Sponge. Not that it's not justified...sometimes.
  • Tsundere: This trope is very zig-zagged as it very much depends on the writer. Some writers portray him as being a Jerk with a Heart of Gold deep down and likes Spongebob, whilst other writers make him a Jerk with a Heart of Jerk who really wants Spongebob gone. Most fans like to think the former.
  • The Unapologetic: He wasn't sorry for reading SpongeBob's diary in "Little Yellow Book", bringing him to tears. But when was chained in town while the people throw tomatoes at him, he asks SpongeBob to forgive him, at least until he reads his real diary.
  • Ungrateful Bastard:
    • In Squidtastic Voyage, when he eagerly screams at Spongebob and Patrick to get out his body without even a thank you for getting the reed out of his throat. This results in a Poor Communication Kills in the end, when he yells "Go!", resulting in Patrick pressing the grow button.
    • Also on Good Neighbors, Squidward had set up a security alarm in his house as Spongebob and Patrick come in without any problem to give him an apology cake and apologize for unknowingly ruining his Sunday. But Squidward tries to get them kicked out instead of accepting their apology.
    • In "Can You Spare a Dime", while initially thankful of Spongebob taking him in from homelessness, Squidward becomes an absolute spoiled brat who refuses to leave and makes Spongebob wait on him hand and foot. And he gets away with it in the end. Almost.
    • The entire episode of "Sponge-Cano" revolves around him admitting that he isn't grateful for anything and complains to everyone that he is the most miserable person in Bikini Bottom. At the end of the episode, Spongebob saves Squidward from falling down the volcano, only for Squidward to tell him that he outright lied to him about being grateful.
  • Vague Age: He's suggested to be older than Spongebob, though how much so seems to vary. Sometimes he appears to be around the same age while others present him as a crotchety middle-aged man.
  • Voluntary Shapeshifting: Into a non-anthro octopus ("Squid's Day Off") and an amorphus liquid ("Suction Cup Symphony").

    Mr. Eugene Harold Krabs 
Voiced by: Clancy Brown
Debut: "Help Wanted"

A scheming skinflint crustacean and owner of the Krusty Krab. His over-the-top greed and cheapness is played for laughs.

  • Abusive Parents: He often neglects Pearl, and his miserly ways cause her no small level of grief.
  • Accidental Pervert: Mr. Krabs thought it was Spongebob behind the shower curtain, but it was actually Spongebob's mom. When she shrieks, he apologizes repeatedly and backs off. Spongebob's dad didn't take this well.
  • Annoying Laugh: Arr-har-har-har!
  • Anti-Hero: Well.. as far as "anti" and "hero" goes, when fighting against a megalomaniac sea plankton he can come of as kind of heroic, sometimes...and at others
  • Arch-Enemy: Plankton.
  • Ax-Crazy: Even Mr. Krabs is often a step away from this because of his extreme obsession with the money. Watch the episode "Clams". This is even more prominent after the movie.
  • Badass: Not only was he in the navy, but he also fought an army of skeletons with a swordfish skull! Then he easily defeated a group of destructive ghosts with a freaking mop!
  • Bad Boss: He has become this, not caring about his employees or his customers and willing to do anything to get a buck, even poison them. He still showed shades of this in the pre-movie seasons; for example, in "Squid on Strike," he decides to start charging Spongebob and Squidward for anything and everything they do that doesn't involve working, including breathing, talking, and even existing.
  • Benevolent Boss: At least toward Spongebob, less so in later seasons, but Spongebob still sees him as one.
  • Berserk Button: Several and almost all of them are money related.
    Mr. Krabs: "FREEEEEEE FOOOOOOOOD?!?!?!?!?!?!??!
    Mr. Krabs: Day... OOOOOOOOOOOOFFFFFF?!?!?!?!
    Mr. Krabs: WHAAAAAAAATTT?!?!?!? YOU THINK I'M A ROBOT?!?!?
  • Big Bad Ensemble: In later seasons, with Plankton. According to Stephen Hillenburg, Mr. Krabs and Plankton are both the main antagonists.
  • Carnivore Confusion: He's a crab, who sells "Crabby Patties"—which, if we can presume it's what it sounds like, are patties made of crab.
  • Clutching Hand Trap: In "Squid's Day Off," he falls prey to one when he tries to retrieve a dime from the sink... and gets his hand stuck. When SpongeBob tells him that he just has to let go of the dime to get loose:
    Mr. Krabs: I can think of ten good reasons to never let go of a dime, boy.
  • Comedic Sociopath: After the movie.
  • Corrupt Corporate Executive: He was originally an Honest Corporate Executive with some greedy tendencies, but he was progressively Flanderized into this - especially in the post-movie seasons.
  • Dad the Veteran: He was in the Navy as a youth, and is now a father to the teenage Pearl.
  • Depending on the Writer:
    • He can either be a sympathetic guy who has a genuine good core, a Jerkass who abuses his employees and doesn't care about his daughter that's Played for Laughs, or a ruthless Smug Snake who commits extremely dark and serious Kick the Dog acts such as relentlessly torturing Plankton that isn't meant to be funny.
    • His obsession with money also varies between episodes.
  • Dub Name Change: In French, he's Capitaine (Captain) Krabs.
  • Easily Forgiven: No matter how badly he treats SpongeBob or how heinous his actions may be, he will always be back in SpongeBob's good graces by the end of the episode. A particularly noticeable example is in "The Cent of Money," in which he uses (and abuses) Gary to steal money and loose change from all of Bikini Bottom, completely uncaring that attracting money causes Gary great discomfort.
  • Even Bad Men Love Their Mamas: He's very caring of his mother, though with the fact that his mother hardly shows up anymore it's hard to tell.
  • Even Evil Has Standards: As recently as "The Masterpiece" he did have far more limits and nobilities in his greed (or at least felt really bad when he overstepped them, like selling Spongebob's soul in the spur of the moment and poisoning people at the Krusty Sponge). Prior to his own development, Plankton often represented boundaries and methods in money making that Krabs drew the line at. In the episode "Little Yellow Book," Mr. Krabs is among the many that are utterly disgusted with Squidward for stealing SpongeBob's diary and reading it to everyone, explicitly telling Squidward, "That's low, even for you." What makes this moment stand out is that Mr. Krabs was NOT one of the people laughing at SpongeBob's secrets, meaning he can't be a Hypocrite.
  • Evil Is Hammy: Krabs can be hammy when it comes to money and has his evil moments.
  • Evil Is Petty: In the episode "Plankton's Regular," he refuses to let Plankton have even one single legitimate customer out of sheer ego.
  • Evil Versus Evil: Him versus Plankton, post-movie seasons. Often, he's actually even worse than Plankton himself.
  • Eviler Than Thou: At times, Plankton himself is shocked and disgusted by the lengths Mr. Krabs is willing to go and what lines he is willing to cross to make a buck.
  • Faux Affably Evil: Under a more negative light post-Flanderization, under a more positive one he falls into more Knight Templar tendencies. Generally how cruel Krabs acts tends to be a case of Rule of Funny or Depending on the Writer, even in later episodes.
  • Four-Temperament Ensemble: The Choleric (shares this with Sandy).
  • Freudian Excuse: One could easily argue that his greed stems from his bad memories of living in poverty until striking it big; as a kid, his clothing came out of the trash.
  • Greed: His entire life revolves around money, to the point where he has physical difficulty just giving up a penny. Heck, he's greedy enough to put Eddy, Mr. Burns, and Wario to shame.
  • Hair-Trigger Temper: When it comes to money. Seriously you can hurt and kill his employees and he won't care, but so much as touch his money and he will flip the entire world around trying to hurt you.
  • Hoist by His Own Petard: Whenever he gets a comeuppance, it's usually a result of this.
    • In "Krusty Towers", he opens the titular hotel, giving it the policy "We shall never deny a guest, even the most ridiculous request." He learns to regret this when Squidward gets fed up with waiting on Patrick hand and foot, quits his job, and then returns as a guest so he can milk the policy for all it's worth.
    • In "The Krabby Kronicle," he starts a tabloid newspaper for money, forcing SpongeBob to write defaming lies in the paper that ruin the reputations of Larry the Lobster, Sandy, Mrs. Puff, and Plankton before eventually telling SpongeBob to "surprise him" with a great story. SpongeBob does so by printing the truth about the stories and what Krabs made him do, which leads to an angry mob taking all of their money back from Krabs en masse.
  • I Fight for the Strongest Side: In "Neptune's Spatula", he gives a little pep talk to Spongebob... before betting his money on King Neptune.
  • It Amused Me: In "Wet Painters," Mr. Krabs convinces Spongebob and Patrick to paint the inside of his house, but states that the paint in question is permanent and if they get even a single drop on anything but the walls, he will chop their butts off and mount them over the fireplace. They accidentally get it on his first dollar, and Mr. Krabs simply licks the paint off and reveals that the paint is actually saliva-soluable. When he tells them that he told them as such just to mess with them, Sponge and Pat are not happy and immediately leave in disgust.
  • It's All About Me: Arguably the most selfish character on the show.
  • Jerkass: Occasionally in early seasons, more often in later seasons.
  • Jerkass Has a Point: Episodes like "Born Again Krabs" suggest that his cheap ways are what keep him in business by affording usual services like electricity or renovations.
  • Jerk with a Heart of Gold: Mr. Krabs was initially a quirky but rather fair natured boss character. He just liked money a bit too much. His greed was often played for laughs, and he had redeeming qualities, such as genuine care for his daughter Pearl, and for Spongebob. Now at times he's just a total jerk to anything without a currency value. There's still some episodes that show him as a good guy though.
  • Karma Houdini:
    • In post-movie seasons, he is essentially the living, breathing incarnate of this trope, considering that he somehow gets away scot-free with anything he does nowadays (ranging from theft to poisoning his customers to even driving people to suicide), sometimes leaving someone to take the blame/pay the price. There are even times near the end of some episodes when it looks like Krabs is about to receive his comeuppance (or in rare cases, actually does), but something happens at the end that puts the situation in Krabs's favor, if not lets him escape punishment entirely.
    • What sat horribly bad with many former fans of the show was Mr. Krabs' treatment of Plankton in "One Coarse Meal". It has been labeled by many as the most disgusting and loathsome episode ever on the show. To elaborate, Mr. Krabs torments Plankton psychologically by dressing up as Pearl (since whales eat plankton) to such a degree that he is Driven to Suicide. And Mr. Krabs just laughs it off. Spongebob later on realizes this is going too far and tells Plankton the truth, but in the end he protects Mr. Krabs and he never gets his comeuppance or shows even a grain of remorse for his deeds. This episode made Mr. Krabs be seen as a heinous Designated Hero and Plankton a Jerkass Woobie by many fans.
  • Karma Houdini Warranty: However, he still doesn't get away with everything. For example, at the end of "The Patty Caper," just as his plan to frame Spongebob for the theft of the Krabby Patty secret ingredient is about to succeed, he reveals the ingredient in his hand and confesses to stealing it himself, and is forced by the judge to give out free Krabby Patties for a whole day, while strapped to the chair and being Forced to Watch by the cops. Might not seem like an actual punishment, but when you're as greedy and miserly as Mr. Krabs...
  • Knight of Cerebus: Becomes one in "One Coarse Meal" where he almost drives Plankton to suicide and loves every minute of it.
  • Knight Templar: His occasional treatment of Plankton leans towards this. Early on he was merely defending his business from his schemes, now he seems to take offense even when his rival is making legitimate profits or merely isn't miserable.
  • Lack of Empathy: Up to Eleven in later seasons. Especially in "One Coarse Meal," where he nearly drives Plankton to suicide just to get a cheap laugh.
  • Large Ham: When it comes to anything involving money.
  • Last Name Basis: Almost everyone calls him Mr. Krabs, rarely using his first name.
  • Laser-Guided Karma: In earlier seasons, and again in most recent ones such as "The Scent Of Money".
  • Lethal Chef: He's a terrible cook, creating a disgusting and freakish "appetizer", which eventually comes to life and begins attacking the restaurant's patrons.
  • Made of Iron: His shell is nearly impossible to scratch. It makes sense because he is a crab.
  • Mean Boss: On his bad days.
  • Money Fetish: His defining character trait. He frequently to ridiculous levels, to the point of taking money-baths, getting into a fight with Squidward over a dime, stalking Spongebob for a penny, and almost losing Spongebob forever in exchange for some pocket change (sixty-two cents to be exact).
  • Mr. Vice Guy: When the show started out, he was a decent guy, but a bit greedy.
  • Never My Fault: Whenever his schemes go wrong, he usually frames someone else; for example, he blames Spongebob for "killing" the health inspector with their "Nasty Patty" even though he himself made the idea in the first place. When Spongebob reminds him that it was his idea, Krabs retorts, "Well, you could've talked me out of it!" That, however, is another example of this trope, as he had explicitly threatened to fire Spongebob if he didn't assist him in the scheme.
    • His rivalry with Plankton began when they blamed each other for messing up the Krabby Patty formula, as it resulted in the death of their first customer.
  • Only in It for the Money: He does everything he can to make more money.
  • Pointy-Haired Boss: He's either this or Mean Boss, Depending on the Writer.
  • Red Baron: Was known as The Golden Claw back in his Navy days.
  • Retired Badass: Was an extremely tough Navycrab in his younger days, as shown in several episodes.
  • Ridiculously Cute Critter: As a baby.
  • Sadist: Post Movie. Especially when it comes to Plankton, perfect examples of this are in "Plankton's Regular" and "One Coarse Meal".
  • Serious Business: He will put other people's lives in danger, even his own, just to make a quick buck.
  • The Scrooge: He is very cheap and reluctant to spend money, so much that he makes Scrooge McDuck look like an angel.
  • The Sociopath: Even more than Plankton, after the movie. He is quite often immoral and insensitive when it comes to crossing the Moral Event Horizon, or whenever he wants to make easy money (which is pretty much all the time).
  • Super Strength: at times, he has been shown to move the Krusty Krab establishment without much effort!
  • Team Dad: He serves as one to SpongeBob and Patrick when it comes to keeping them on the right track from time to time, examples include "Hooky" and "Sailor Mouth".
  • Tiny Guy, Huge Girl: He's a crab and his daughter is a whale. If supplemental materials are to be believed, he was also this with his wife.
  • Token Evil Teammate: In later seasons.
  • Took a Level in Dumbass: He can completely lose rational thought in the face of money.
  • Took a Level in Jerkass: After the movie.
  • Unscrupulous Hero: When against Plankton.
  • Unsympathetic Comedy Protagonist: Especially in later seasons.
  • Villain Protagonist: Post-Movie. Though it still depends.
  • We Used to Be Friends: With Plankton. It was the Krabby Patty Formula that caused them to become Arch Enemies with each other.

    Sandy Cheeks 
Voiced by: Carolyn Lawrence
Debut: "Tea at the Treedome"

An athlete/scientist squirrel from Texas.

  • The Ace: Particularity as her appearances get less frequent.
  • Action Girl: Much more so in earlier episodes, though it still shows through every now and then.
  • Adorkable: Like her friend Spongebob, she's cute and eccentric. Not to mention extremely nerdy, which causes Spongebob and Patrick to often scratch their heads in confusion whenever she talks Science.
  • Badass: Easily one of the coolest...
  • Badass Adorable: and cutest characters in the show.
  • Badass Bookworm: Easily the most intelligent in the main cast, but often shown to be as physically strong as Larry the Lobster. Also likes life-threatening stunts.
  • Bare Your Midriff: When she not wearing her suit filled with oxygen she wears a purple bikini top.
  • Berserk Button: Never ever insult anything/anyone from Texas, or even the state itself. You will regret it, as Spongebob and Patrick faced the serious consequences.
  • Broken Ace: Light case in some episodes, due to her very competitive attitude. She takes the idea of not being the best at something rather badly.
  • Closer to Earth: Flip flops with this. While she is far more intelligent than most of the cast, she is occasionally shown to have a very rowdy and abrasive temperment when pushed. She is also sometimes more aware of her position in this trope than she really is. Granted as the rest of the cast became Flanderized more and more, her own flaws became less significant.
  • Competition Freak: Sandy is used to being the best at multiple talents and sports, so gets rather aggressive with when challenged.
  • Cute Bruiser: She is clearly Bikini Bottom's strongest resident, occassionally challenging massive, heavily muscled fish and Larry the Lobster to weightlifting challenges.
  • Demoted to Extra: Inverted: She and Gary are more common in merchandise than the show.
  • Enraged by Idiocy: Quite expresses her annoyance towards Patrick's stupidity on occasions.
  • Everything Is Big in Texas: She's the size of a flea compared to the Texas landscape.
  • Fish out of Water: Played straight, though she's actually a squirrel IN water.
  • Flanderization: Originally portrayed as The Ace in various activities, post-movie episodes have increasingly focused on her being a scientist, pretty much shunning anything else she was passionate about.
  • Flat Character: Became this in the post movie seasons.
  • Four-Temperament Ensemble: The Choleric (shares this with Mr. Krabs).
  • Gadgeteer Genius: She built tons of nifty gadgets.
  • Genius Bruiser: She's smart and tough.
  • Genki Girl: She can be this when she wants to have a good time.
  • Hair-Trigger Temper: Usually level headed, but being a Hot-Blooded Texan, she is rarely subtle when her temper flares.
  • Insufferable Genius: Sometimes, especially in later seasons.
  • Invisibility: As Miss Appear in "Mermaid Man and Barnacle Boy V".
  • The Lad-ette: By many fan interpretations.
  • Masculine Girl, Feminine Boy: Masculine Girl to SpongeBob's Feminine Boy.
  • Noble Bigot: In "Pressure," she repeatedly bragged that land creatures are better than sea creatures, with Spongebob, Patrick, Squidward, and Mr. Krabs thinking the opposite. However, after their attempts at proving it put both sides in mortal danger, they grow out of it.
  • Not So Above It All: Though, sometimes her sciencey-mind can make her do some things that push her into Mad Scientist territory.
  • Only Sane Woman: Not as much as Squidward, but she's still fairly level-headed. This is the reason why Squidward has no problem with her.
  • Out of Focus: Appears less and less with each season, it seems.
  • Parody Sue: A few episodes, especially in the 2nd season, seem to make light of her somewhat lengthy amount of talents and positive aspects, it also usually being these points she was portrayed in a more flawed light. May count as an example of Rescued from the Scrappy Heap with those elements considered.
  • Passionate Sports Girl: To a particularly extreme level. Adding to that her occasional Competition Freak bouts, working out with Sandy can border out and out life threatening.
  • Positive Discrimination: Arguable example. Is the most gifted and least flawed central character by miles, though partly due to excessive Flanderization of the bipedal, male characters. Admittedly it is also balanced by frequent Not So Above It All moments. She played it undeniably straight pre-Character Development however.
  • Ship Tease: Usually with SpongeBob, shown by how well they interact with one another, and some reactions to each others comments. One Flashback from "Truth or Square" even had them seemingly getting married, only for it to be revealed as a play after an Almost Kiss.
  • Slapstick Knows No Gender: Not as much as the others but Sandy suffers some physical damage at times, such as being mauled by a gorilla, having her fur torn off by Spongebob and Patrick, being plagued with fleas, being hit by a car off of a mountain and so on.
  • Small Name, Big Ego: Albeit not as consistently as Squidward. Here are some examples:
    • In "Pressure," she repeatedly stated that land creatures are better than sea creatures and went so far as to almost drown herself in an attempt to prove it.
    • Then there's "Sandy, SpongeBob, and the Worm," where she was firmly convinced that, being "Texas tough," she could easily handle the Alaskan Bullworm, repeatedly dismissing and even mocking SpongeBob's warnings. When she finally reaches it and finds out that the Alaskan Bullworm is indeed as big and dangerous as everyone said, she runs in fear, and only admits she was wrong after SpongeBob nagged her into doing so.
  • The Smurfette Principle: Sandy is the only female who can be considered a main character, and her appearances are becoming less frequent.
  • Southern-Fried Genius: She's from Texas, and proud of it!
  • Super Strength: Pretty obvious, actually. Especially when you saw her pull a boat underwater by the chain in "The Worm".
  • Tertiary Sexual Characteristics: She wears a flower on her diving helmet so it's more readily apparent she's a girl. She's got eyelashes too, but so does Spongebob.
  • Token Good Teammate: The only main character that isn't either a Jerkass or a moron. She and Pearl are the only characters Squidward gets along with very well for this reason. Her occasional ego and temperament can provoke some unfortunate situations in the show (eg. "Pressure"), that said, she is arguably the one recurring character that hasn't had her flaws Flanderized over her redeeming aspects.
  • Too Clever by Half: Every now and then she goes into this.
  • Trademark Favorite Food: Nuts and anything nut-related.
  • Walking Swimsuit Scene: Occasionally, but always when she's in her tree house.
  • Women Are Wiser: Usually played straight to a tee, though she has occasional lapses in judgement Spongebob plays The Straight Man towards, especially in early seasons.

    Sheldon J. Plankton 
Voiced by: Doug Lawrence
Debut: "Plankton!"

Krabs' business rival and arch-enemy. Is always after the formula for the Krabby Patty, the burger that SpongeBob fries up to the customers. Barring that, he ultimately aims for crushing all of Bikini Bottom beneath his feet.

  • Affably Evil: He is no less pleasant than his rival can be anyway.
  • Arch-Enemy: To Krabs, and sometimes SpongeBob.
  • Badass Bookworm: He is shown to be a technological genius, capable of creating complex machines and powerful robots, as well as plotting various elaborate, and nearly successful evil schemes.
  • Bad Boss: While Karen dishes as much abuse as she takes, Plankton is frequently dismissive and insulting to her and isn't against using her as patsy or guinea pig for his experiments.
  • Big Bad: The primary antagonist of both the series and The Movie.
  • Body Snatcher: A few of his plans involve mentally or physically enslaving someone with or without them being aware of the situation.
  • Breakout Character/ Breakout Villain: He only occasionally appeared early on, generally when episodes needed an actual "villain" character, but he has continued to appear more and more frequently as time has gone on, to the point of being in many more episodes than either Sandy or Gary.
  • Butt Monkey: Just how many times has he been stepped on and thrown?
    • Iron Butt Monkey: A-lot, but he usually walks out of it okay. Deconstructed though, as while he can take a lot, it's strongly hinted that he became so resilient because he HAD to due his status as a plankton. It's also made clear that, resilient or not, it still bothers him on some level.
  • Can't Get Away with Nuthin' : Not just with his evil plans. A rather discomforting example would be "One Coarse Meal", where Plankton is punished for trying to exact justifiable revenge on Mr. Krabs, who in turn got off scot-free after tormenting Plankton for several days.
    • However, Plankton does partially get away in "Someone's in the Kitchen with Sandy". After yet another failed attempt to steal a Krabby Patty, he is locked in a jar of spicy mustard. Then the police show up and - instead of arresting Plankton for stealing Sandy's pelt - they arrest SANDY for public nudity.
  • Card-Carrying Villain: He likes to talk about how evil he is.
  • Catch Phrase: "I went to college!"
  • The Chessmaster: In the movie.
  • Corrupt Corporate Executive: Although the Chum Bucket could hardly be considered a corporation...
  • Crouching Moron, Hidden Badass: In the movie.
  • Cut Lex Luthor a Check: Trope Codifier. He's a scientific genius, and could easily get a career in technology if he wasn't so obsessed with running the Krusty Krab out of business.
  • Cyclops: Justified, he's a plankton and many plankton are cyclops.
  • Deadpan Snarker: Though not nearly as profound an example, he can dish it back to Karen at times.
  • Depending on the Writer: How evil he is tends to vary from episode to episode. He's always a villainous character, but his antics are frequently overshadowed by Mr. Krabs later on.
  • Determinator: Much much more so in earlier episodes, but there are some later episodes in which he's given up.
  • Ditzy Genius: He may be a scientist and have all sorts of gadgets, but is incompetent overall. For example, he believes that baby powder is made from actual babies in "Goo Goo Gas," and in "Komputer Overload," he has to be reminded to blink.
  • The Dog Bites Back: In "One Coarse Meal", when he nearly kills himself after being frightened by Mr. Krabs in disguise as Pearl from his fear of whales for 17 straight days, he finds out about Mr. Krabs's fear of mimes and starts scaring him with that. It doesn't last long, though.
  • Driven to Suicide: Almost happened in "One Coarse Meal."
  • Embarrassing First Name: Karen had a really good time with this one.
  • Even Bad Men Love Their Mamas: Actually his grandmama.
  • Even Evil Has Standards:
    • In "The Krabby Kronicle," he doesn't invade people's privacy for a newspaper gossip and shows disgust at Krabs' greed. Quoted by him "And I thought I was evil!"
    • In "Squirrel Records," Sandy comes to him asking for raw chum in order to break a world record. Plankton is actually reluctant to give it to her despite freely admitting to being an "evil, heartless mastermind," because, as he puts it, "no one can eat raw chum and survive!"
  • Evil Cannot Comprehend Good: In "Walking Small", he's driven to a Villainous Breakdown after SpongeBob resolves to be "aggressively nice".
  • Evil Counterpart: To Mr. Krabs, at least in earlier seasons.
  • Evil Feels Good: As quoted in "F.U.N.":
    Plankton: Being evil is too much fun!
  • Evil Former Friend: Towards Mr. Krabs.
  • Evil Genius/Evil Is Hammy/Evil Laugh: He's smart, hammy as hell, and laughs evilly quite a lot.
  • Evil Sounds Deep: Downplayed later on the show.
  • Failure Is the Only Option: With an exception in 'Wishing You Well'.
  • Friendly Enemy: Spongebob on many occasions tries to befriend or show pity on Plankton, with varying success.
  • Glad I Thought of It: He's guilty of this, especially when he takes an idea Karen says to him.
  • Hair-Trigger Temper: Much more so in earlier episodes, he's calmed down a tad in later episodes.
  • Harmless Villain/Not-So-Harmless Villain: Played with, his only interest is stealing Krabs' secret formula. However depending on his overzeal, he is willing to brainwash, potentially murder and generally cause a lot of collateral damage in his attempts to do so. In other episodes that aired after the movie, he even settles for just competing with Krabs legitimately. When he falls into his Analyzer in his debut episode, it describes him as being made of "1% evil, 99% hot gas."
  • Henpecked Husband: Has shades of this around Karen.
  • I'm a Humanitarian: in Krabby Kronickles, as ode to Soylent Green
  • Impossible Thief: In one episode, Mr. Krabs tempts a "reformed" Plankton with a krabby patty. Despite the fact that the patty is always visible and untouched on the table throughout the exchange, it somehow ends up replaced with a cardboard cutout, which Krabs should have seen from his angle, even when it was propped up.
  • Ineffectual Sympathetic Villain: In later seasons, but it varies, as sometimes he manages to be the clear cut villain. Depending on the Writer.
  • Jerkass: When he's the main villain, he'll be as mean as he is evil.
  • Jerkass Has a Point: In "Walking Small." True, he may have been using Spongebob as an Unwitting Pawn at the time, but he nonetheless makes a valid point when he calls Spongebob out on being an Extreme Doormat.
  • Jerk with a Heart of Jerk: In the first season episode "FUN".
  • Knight of Cerebus: In The Movie, He's actually played seriously.
  • Large Ham: Despite his small size.
  • Last Name Basis: Though in his case, he considers Sheldon an Embarrassing First Name. Unlike Mr. Krabs, he's simply called Plankton instead of Mr. Plankton (sans one episode where he sees what it's like if they switch places).
  • Laughably Evil: He's an Evil Genius who chews up the scenery.
  • Leitmotif: In-Universe. He carries his gramophone to play one, but only in his first appearance. It sometimes plays without the need of a gramophone.
  • Lethal Chef: The reason why he doesn't have customers.
  • Likes Older Women: He is attracted to Mr. Krabs's mother in one episode.
  • Mad Scientist: Emphasis on mad.
  • The Napoleon — Being constantly stepped on and flung around like a piece of trash will mess with a plankton's mind, man.
  • Near Villain Victory: "SpongeBob's Last Stand" is the closest Plankton has ever gotten in the cartoon series, with Mr. Krabs completely willing to hand over the secret formula. In one episode, he already figured out every ingredient in a Krabby, save for one, which was the Macguffin of that episode. This also goes for any scheme that DOESN'T involve stealing the secret formula.
  • Nice Guys Finish Last: Says this word-for-word in "Walking Small".
  • No Celebrities Were Harmed: Voice actor Doug Lawrence modeled his voice off of Thurl Ravenscroft.
  • Not Me This Time: In "The Patty Caper," he's naturally the first suspect when SpongeBob and Patrick try to find out who stole the key ingredient to the Krabby Patty formula. However, for once, it wasn't him.
  • The Noseless: Justified, planktons don't have noses
  • Omnicidal Maniac: he vows to be one in the end of The SpongeBob SquarePants Movie.
  • Pet the Dog: The episode Plankton's Pet. He's genuinely nice to his pet amoeba Spot, feels guilty about having to punish him, and willingly works with Spongebob to find him.
  • The Pirates Who Don't Do Anything: He's ostensibly a chef/restauranteur, but it's easy to forget this when his status as a Card-Carrying Villain dominates his characterization, and when the Chum Bucket resembles a Supervillain Lair more than it resembles an actual eatery. He seems to spend more time plotting Mr. Krabs' downfall (and occasionally trying to Take Over the World) than, y' food and trying to attract customers.
  • Red Eye Take Warning: Subverted, he's usually pretty harmless.
  • The Rival: To Mr. Krabs.
  • Seldom-Seen Species: He's undoubtedly the most popular (and only) plankton in fiction.
  • Sesquipedalian Loquaciousness: Often uses strong vocabulary.
  • Smug Snake: Sometimes.
  • Species Surname: His full name is Sheldon J. Plankton, and he's a plankton.
  • Super Strength: Shown in "Bucket Sweet Bucket", where he crushes a nut with his teeth & punches the door off of a safe... from the inside, but normally subverted.
  • Take Over the World: His secondary goal, Depending on the Writer.
  • Throw the Dog a Bone: Gets a legitimately happy ending in both Plankton's Pet and Wishing You Well.
  • Took a Level in Badass: After stint of Villain Decay Plankton returned to his threatening and menacing self by Season 7 and became a much more competent villain. Particulary in episodes "Frozen Face-Off", "Spongebob's Last Stand" and "One Coarse Meal'. In "Frozen Face-Off" he organized a race as a distraction just so he could steal the Krabby Patty formula without trouble and to throw off the suspicion he placed his robot doppelganger to participate in the race and it took all the main characters to stop his Evil Plan. In "Spongebob's Last Stand" where he built a super highway, which directly led to Chum Bucket, and it drove away all jellyfish from their fields and took over town and almost all of Bikini Bottom's population supported him until the jellyfish attacked them in revenge for their home's destruction. It was so bad that Mr. Krabs was going to give him the secret formula willingly. This and "Frozen Face-Off" are more dramatic and action packed episodes of the series. Even in "One Coarse Meal', where he was Driven to Suicide due to Krabs masquerading as Pearl and scaring him, Plankton was very effective villain. He drops a powerful explosive the size of a TV remote on the Krusty Krab's roof; he is said to build a transmutator (a machine with the power to make an element in nature into another element, like iron into gold, fire into air, etc.); and a robotic bomb-shaped object that is actually a disguised, robotic, telescopic claw that can crush a sea creature. And at the end of the episode, Plankton uses mimes to scare Mr. Krabs, who is very afraid of mimes, as the revenge for Mr. Krabs scaring him and driving him to suicide and from looks of it, Mr. Krabs' fear of mimes is bigger than Plankton's fear of whales, since Plankton managed to remain rational while being scared by whales, while Mr. Krabs was completely irrational.
  • Took a Level in Dumbass: Sometimes. He varies from being on Sandy's level in terms of intelligence to being barely smarter than other characters.
  • Tragic Villain: For some, he could be seen like this. It is known that as a child, he was bullied and his only friend was Mr. Krabs. Now he is evil and despises society, not only because of this, also for a dispute with Mr. Krabs for poisoning the old man Jenkins.
  • Unknown Rival: Sometimes SpongeBob doesn't acknowledge him as an enemy.
  • Villainous Breakdown: He has one in The Sponge Bob Square Pants Movie. After his helmets have been proven to be defeated by the Power of Rock, he tried to desperately beg his computer wife Karen to do something about SpongeBob. However, she was being carried off by the crowd and was too far away to hear her husband. As one final act of desperation to keep his control over the townspeople, he tried to command the brainwashed King Neptune to kill SpongeBob. Unfortunately for him, the helmet on Neptune's head was also destroyed, and he was freed from his mind control. Plankton then tried to escape through the front doors, only to be paved down by the freed Bikini Bottomites. He's later arrested, and he threatens to murder everyone once he gets out of prison.
  • Villain Episode: "The Algae's Always Greener" and "Plankton's Army" are a couple of good examples for him.
  • Villain Protagonist: Only in some episodes, showing his attempts to steal the Krabby Patty formula.
  • Villain Song:
    'Plankton: ♪F is for fire that burns down the whole town, U is for uranium... bombs! N is for no survivors, when you-♪
  • Vocal Dissonance: He has quite a deep, booming voice, in contrast to his miniscule size.
  • Vocal Evolution: Starting in the movie, he would develop a high-pitched scream.
  • Wounded Gazelle Gambit: Fakes an injury to get the Krabby Patty Formula in "Krabs vs Plankton".
  • Your Cheating Heart: As soon as he gets attracted to Mr. Krabs' mom, he shuts Karen down and goes after her. However, this could be debated since Karen is not a real organic being, just a computer.
  • Your Size May Vary: We all know that Plankton is...well, small, but how small he is has a tendency to vary. This is especially the case in his debut episode.
  • 0% Approval Rating: Has been referred to as the "most hated thing/creature in Bikini Bottom" on more than one occasion.

Voiced by: Jill Talley
Debut: "Plankton!"

Plankton's business computer and robotic spouse. Being blessed with a complex sentient programming, Karen is well aware of her "husband's" stupidity and is very verbal about it as well.

  • Actually Pretty Funny: Sometimes snarks or titters at Plankton's abuse.
  • A.I. Is a Crapshoot: Seems more competent and intelligent than Plankton, but also has the personality of a nagging housewife, and thus is usually more preoccupied in nagging at her husband's failures or whining for affection.
  • Beleaguered Assistant: She mostly averts this as she is generally the dominant one in the relationship.
  • Character Development: Was originally a generic computer in her debut in "Plankton". Was granted a sentience in later episodes.
  • Deadpan Snarker: Of the tallest order.
  • Flanderization: Her Deadpan Snarker mannerisms. Initially merely acted frustrated and sarcastic on odd occasions due to Plankton's bumbling. Now she is perpetually throwing insults at her spouse.
  • Green Eyes: Whenever she has them, otherwise Subverted.
  • Hyper Competent Side Kick: She successfully stole a Krabby Patty first time she tried alone with near zero effort (then again, it was against Squidward).
  • Just a Stupid Accent: Had an obnoxious Boston accent even before she had a personality.
  • Lack of Empathy: Well, she's a computer...
  • Pet the Dog: Perpetually snarky and nagging towards her husband, and is suggested to even find some of his suffering amusing, nevertheless she does love him, deep, deep down.
  • Robotic Spouse: Yes and no. Yes, Karen is a robot (okay, she's technically an extremely sarcastic computer...). Yes, she is married to her creator. No, however, Plankton did not create her just to marry her. She was originally just the security system for the business he and Mr. Krabs ran together, before they began dating naturally.
  • Satellite Character: She has very sparse interaction with anybody other than Plankton. Justified, seeing as how she's a mostly immobile computer...
  • Snarky Inanimate Object: She's a robot, and damn if she ever isn't snarky.
  • Tuckerization: Named after Stephen Hillenburg's wife.

Debut: "Help Wanted"

SpongeBob's pet snail, who meows like a cat.

Recurring Characters

    Mrs. Poppy Puff 
Voiced by: Mary Jo Catlett
Debut: "Boating School"

Neurotic boating school teacher, driven (almost literally) to wit's end by Spongebob's constant disasterous attempts to gain a boating license.

  • Adults Are Useless: Sort of. She's far more level headed than Spongebob, but she shows occasional incompetance as a teacher.
  • Alliterative Name: Poppy Puff.
  • Ambiguous Disorder: Several episodes demonstrate that SpongeBob='s] antics have taken quite the toll on her mental health. "Doing Time" ends with her having repeated hallucinations of the episode's beginning, and in "Krusty Love," she has a very [=PTSD-like reaction by just hearing SpongeBob's voice.
  • Ax-Crazy: In "Demolition Doofus" when she becomes obsessed with attempting to get Spongebob killed in a demolition match, and tries to kill him herself when that fails.
  • Butt Monkey: As a result of Spongebob's antics.
  • Closer to Earth: Despite the occasional dark tint, she's one of the more level headed characters. Spongebob is constantly grating on her sanity however.
  • Dark and Troubled Past: According to at least one monologue, she has previously skipped town under a different name.
    • Also, her husband was apparently fished up out of the sea and made into a lamp.
  • Determined Widow: Amazingly, she hasn't given up on Spongebob.
  • Didn't Think This Through: She falls victim to this in the episode "No Free Rides." Sick and tired of having to go through SpongeBob's chaotic driving tests, she comes up with a bogus extra credit test to just give him his driver's license and get him out of her classroom. It's only after she does so that it hits her that she has just given SpongeBob free reign to drive on public streets and wreak havoc there.
  • He Who Fights Monsters: Compared to the already hostile and mean tempered Squidward, Mrs Puff is a docile, well meaning character whose nerves have slowly been worn at by Spongebob's behaviour. Several episodes have shown her take increasingly desperate and sometimes unscrupulous measures just to finally get away from him.
  • Knight of Cerebus: She briefly becomes one in the Season 8 episode Demolition Doofus. She entered SpongeBob into a demolition derby and hoped that he would die in it since he was the one who caused her to puncture her inflation sac thanks to his crazy driving. She later tries to kill him herself by entering into the demolition derby using a massive monster truck. This episode is considered her darkest role by many fans.
  • Nervous Wreck: She's very neurotic, although it's usually justified.
  • No Accounting for Taste: Once dated Mr. Krabs.
    • Granted, this was back in the second season where he was still a decent guy and before he became more of a Jerkass.
  • Not So Different: From Squidward. In Boating Buddies, she and Squidward agree that Spongebob is the bane of their existance.
  • Out-of-Character Moment: In the infamous Demolition Doofus, she is driven insane after one of SpongeBob's accidents causes her to deflate. She actually tries to get SpongeBob killed in a demolition derby. Thankfully, she was turned back to normal at the end.
  • Out of Focus: Post movie.
  • Running Gag: How many times has she gotten arrested now?
  • Sanity Slippage: Happens to her when it involves Spongebob.
  • Stepford Smiler: Implied.
  • Temporarily a Villain: In No Free Rides and Demolition Doofus.

Debut: "Ripped Pants"

    Mermaid Man 
Voiced by: Ernest Borgnine
Debut: "Mermaid Man and Barnacle Boy"

Spongebob and Patrick's favorite Superhero, who is now elderly and lives in a retirement home.

  • Cloud Cuckoolander: May be semi-justified as onset Alzheimer's/Dementia.
  • Expy: Of Aquaman, and a deconstruction at the same time. His younger self also looks like Aquaman, and both have the ability to summon the creatures of the sea via telepathy. He's also clearly modeled off of Batman - particularly, the television version.
  • Fake Ultimate Hero: Of sorts. His and Barnacle Boy's heroism after becoming semi-retired is only informed. When they appear in an episode, it's usually SpongeBob and Patrick who end up saving the day.
  • Ink-Suit Actor: Looks exactly like Ernest Borgnine.
  • I Was Quite a Looker: Compare his elderly appearance to his younger self.
  • Large Ham: EVIL! EVIL!
  • Leitmotif: The Lineman.
    • Song Association: It has existed before Spongebob was created, but most people think of it as the "Mermaid Man and Barnacle Boy" theme.
  • Old Superhero: Was retired, but became "semi-retired" thanks to SpongeBob.
  • Senior Sleep Cycle: He can even sleep with his eyes open.
  • Put on a Bus: Hasn't appeared since Ernest Borgnine's death on July 8th, 2012.
  • Token Human: And yet he is able to survive underwater.

    Barnacle Boy 
Voiced by: Tim Conway
Debut: "Mermaid Man and Barnacle Boy"

Mermaidman's sidekick, who is also elderly and lives in the same retirement home.

    The Flying Dutchman 
Voiced by: Brian Doyle-Murray
Debut: "Squidward the Unfriendly Ghost" (in a magazine), "Scaredy Pants" (in-person)

    Patchy the Pirate 
Played by: Tom Kenny
Debut: "Christmas Who?"

The president of SpongeBob's fan club.

    Potty the Parrot

Debut: "Christmas Who?"

    SpongeBob's Gramma (Grandma SquarePants) 
Voiced by: Marion Ross
Debut: "Grandma's Kisses"

    Man Ray 
Voiced by: John Rhys-Davies (first two appearances) and Bob Joles (all subsequent appearances)
Debut: "Mermaid Man and Barnacle Boy III"

  • Arch-Enemy: To Mermaid Man and Barnacle Boy.
  • Expy of Black Manta
  • Eye Beams: His only legitimate superpower. If the newscast from "Mermaid Man and Barnacle Boy V" is to be believed, he can vaporize entire houses with it.
  • Heel-Face Revolving Door: Seemed to pull a Heel-Face Turn in his first appearance, but afterwards reverts to his evil status by the next time we see him. In his third appearance though, he preferred living a normal life, but Spongebob got on his nerves when he didn't do anything wrong at all. Any evil he's done outside of the Bad Future amounts to Poke the Poodle in "Mermaid Man and Barnacle Boy V" or just being a villain for hire when he teamed up with Plankton.
  • Human Popsicle: He was frozen in tartar sauce since Mermaid Man's prime, until SpongeBob and Patrick freed him.
  • Large Ham: Especially when he's doing his Evil Laugh.
  • Not-So-Harmless Villain: A minor villain in the normal series, but a Bad Future where he won proved he was actually able to take over the world and turn it into a dictatorship where everyone was enslaved to his will.
  • Red Eyes, Take Warning He has red eyes, and he's evil.
  • Sealed Evil in a Can: In his debut episode, he was frozen in tartar sauce until SpongeBob and Patrick accidentally thawed him out.
  • Token Human: Well, he's human-like, it's still not clear if he's actually human or not.

    Squilliam Fancyson 
Debut: "Band Geeks"

Squidward's rival from high school. Squilliam is essentially everything Squidward dreamed of being. Whereas Squidward is a middle-class jackass stuck in a dead end job and considered a joke by everyone except SpongeBob and Patrick, Squilliam is a successful, filthy stinking rich jackass beloved by all. Also, unlike Squidward, who has had a few Pet the Dog moments, he appears to have no redeeming qualities whatsoever. He loves rubbing his success in Squidward's face.

  • The Ace: Is this compared to Squidward.
  • Alpha Bastard: Apart from the fact that he's not a highschooler, he fits this trope to a T.
  • Always Someone Better: He's far more successful than Squidward ever was or will ever hope to be.
  • The Bad Guy Wins: Won twice, but normally his appearances are a sign Squidward will win this one.
  • Big Ol' Unibrow: Type I
  • Dub Name Change:
    • Siegbert Schnösel in the German dub.
    • Hjalmar von Kalmari in the Finnish dub.
    • Octavius Bläckenberg in the Swedish dub.
    • Squilliam Elegant in the Italian dub.
  • Eviler Than Thou: Well neither are exactly evil, but he's this to Squidward. Take Squidward, add some Smug Snake and several levels in jerkassitude, and remove any redeeming qualities. That's Squilliam.
  • Hate Sink: Squilliam has almost no sympathetic qualities about him, making it all the easier for one to root for the normally jerkassy Squidward.
  • Hoist by His Own Petard: In "Band Geeks" and "House Fancy"
  • Humiliation Conga: In the iconic scene of "Band Geeks"
    • Gets another one at the end of "House Fancy".
  • Jerkass: Mean, selfish, arrogant and takes great delight in rubbing his wealth and success in Squidward's face.
    • Jerk with a Heart of Jerk: Squilliam treats his friends to dinner in Squilliam Returns though it's most likely to show off his wealth.
  • Lean and Mean
  • Narcissist: Ironically, one of the only things he has in common with Squidward, and possibly with every member of his species.
  • Rich Bastard: He has a private jet, private yacht, private airship, private casino, etc.
  • The Rival: To Squidward.
  • Smug Snake: He never misses a chance to rub his success in Squidward's face.
  • Talkingto Himself: With Squidward in the German and Latin-American dubs.
  • Villainous Breakdown: At the end of "Band Geeks", he has one. Seeing Squidward completely succeed in an absolutely epic way causes him to have a heart attack!. Has another one at the end of "House Fancy" where Squidward's house being declared even fancier than his leaves Squilliam laying on the ground crying his eyes out.

    Doodle Bob 
Voiced by: Paul Tibbit
Debut: "Frankendoodle"

SpongeBob and Patrick's creation, a crude doodle of SpongeBob come to life, and on an Unstoppable Rage.

Voiced by: Creator/Carlos Alazraqui
Debut: "Ripped Pants"

A surfer fish who appears mostly in the background, but has some major roles.

    Bubble Bass 
Debut: "Pickles"

An obese, picky fish who was a recurring nemesis to Spongebob in the first season.

  • Big Eater: A fan translated his order to be a Krabby Patty with over twenty patties. Plus, he took off running when Spongebob threw a single piece of popcorn.
  • Demoted to Extra: He played a major role in "Pickles" and was built up as a recurring enemy of Spongebob's, but completely disappeared from the show for years. His return was a Wham Shot among Wham Shot's. Even still, this is the only appearance he's made since the first season. He does pop up in video games from time to time.
  • Fat Bastard: He's really not very nice, nor is he fit. When he's fleeing the Krusty Krab when he's been exposed, he's wheezing as he pathetically lumber-jogs off.
  • Jerkass: He's this more than anything else - in his first appearance, he nearly robbed Spongebob of his self-confidence for no reason whatsoever.
  • Meaningful Name: Say his name repeatedly and quickly and you'll discover why the name is perfect for him.
  • Pet the Dog: In his most recent appearance, he came to thank Plankton for rescuing him.
  • Remember the New Guy: Somewhat of an example; in his few appearances he was treated as a recurring nemesis.
  • Unsatisfiable Customer: Type 4, since he was making false complaints for SpongeBob's flawless service, either for a free Krabby Patty or just to Mind Screw SpongeBob For the Lulz.

    The Dirty Bubble 
Debut: "Mermaid Man and Barnacle Boy II"

  • Chuck Cunningham Syndrome: Anyone remember the last time he showed up?
  • Hidden Depths: Apparently he's a Paddle-ball champion with a consecutive hit score of over 5 million.
  • They Killed Kenny: Killed in "Mermaid Man and Barnacle Boy II", but reappears alive and well in "Mermaid Man and Barnacle Boy V". This might be because he's a bubble and presumably can reform as long as there's enough of him left to make up a new body.
  • Weaksauce Weakness: "Watch the POINT!!!"
  • We Hardly Knew Ye: Subverted. In his debut, he is quickly killed by Spongebob (by complete accident) less than a minute after he shows up, but is seen alive and well in his second appearance.

Voiced by: Various
Debut: "Ripped Pants"
A fish well known for saying "CHOCOLATE!"

    • When Spongebob says "April Fools" when he gives him back his drink, he grabs Spongebob by the shirt and screams, demanding to know what he's done.
    • When Bubble Buddy first was in Bikini Bottom and wreaked havoc, he piped up with this exchange.
    Tom: He burned our crops, poisoned our water supply, and delivered a plague unto our houses!!!
    Townspeople: He DID?!?
    Tom: No! But are we gonna wait around until he does?!?
  • Comedic Sociopath: To some extent.
  • Palette Swap: Into red and lime green.

Voiced by: Paul Tibbit,(first two appearences) and Sirena Irwin(Enemy In Law and onward)
Debut: "Sailor Mouth"

Mr Krabs mother, and grandmother to Pearl (although the two haven't been seen together).

  • Berserk Button: See Mama Bear. Also, she was furious when she thought Plankton was just using her to get the Krabby Patty secret recipe.
  • Good Parents: She seems to be a loving, fair, but firm mother to Mr. Krabs and also is willing to discipline Spongebob and Patrick on occasion.
  • Mama Bear: Do not mess with her son.
  • Older Than They Look: Looks about 20 years younger than she is.

    Uncle Sherm Square Pants 
Debut: "Krab Borg" (mentioned), "Pest of the West" (seen in a photo)

The guy seen in various episodes to say his famous catchphrase ("MY LEG!") after something bad happens to him.

  • Catch Phrase: MY LEG!!! and DEAUUGH!!

  • Palette Swap: He is in both brown and blue versions.
    • There is a brown-green version used only once, in Professor Squidward.

Debut: "Blackjack"

Grandpa Redbeard

Voiced by: Dennis Quaid
Debut: "Grandpappy the Pirate"

  • Really 700 Years Old: If Mr. Krabs was really born in 1942 and his mother is still alive, he must be really old, considering the setting after the events on SB-129 (It took place in 2017).
  • Will Not Tell a Lie: His rule for pirates.


Voiced by: Thomas F. Wilson
Debut: "Sandy's Rocket"

  • Ascended Extra: He was a background character for a few early episodes before coming into the spotlight as the infamous bully he's known as now.

Voiced by: John O Hurley,(TV Show) and Jeffery Tambor(The Sponge Bob Square Pants Movie)

Kevin the Sea Cucumber

Voiced by: Dee Bradly Baker
Debut: I'm Your Biggest Fanatic

  • For the Evulz: He picks on and belittles Spongebob and then tries to drive him off a cliff for no apparent reason behind his own amusement. And later it's implied that he's done this to all of his "biggest fans".
  • Jerkass: And how!
  • Karmic Mutilation: He doesn't die, but he does get the fronds on his head torn off at the end of his episode. It should be Body Horror, but he deserved it for the massive jerk he was being.
  • Know-Nothing Know-It-All: The end of his first appearance reveals that he actually knows nothing about jellyfish, and the only reason he got into jellyfishing in the first place was because of the merchandise.
  • Nice Hat: Subverted.
  • Noodle Incident: The King Jellyfish gets really angry when it sees him, implying that the two have some sort of history. It even bellows his name the minute it notices him.
    King Jellyfish: KEEEEEEVIINNNNN!!!
  • Smug Snake: Constantly attempts to sabotage Spongebob's attempts to get into the Jelly Spotters and is always convinced that his plans won't fail. Except they do fail. Constantly. And hilariously.

Johnny Erain, AKA Realistic Fish Head

Debut: Mermaid Man and Barnacle Boy II

  • Chuck Cunningham Syndrome: His appearances after season 3 dwindled, save for in appearances in one episode per season, in Season 4, 6, 7 and 8.
  • Only Known by Their Nickname: Meta-example; Most fans are unaware of his actual name, so when most people discuss him, they call him "The Realistic Fish Head". It doesn't help that the nickname is how he introduces himself.

Evil Granny

Debut: Have You Seen This Snail?

  • Expy: Appears to be one of the evil granny in the Renand Stimpy episode "It's a Dog's Life". Only Gary's lucky this time.
  • Fattening The Victim: It's unknown if she actually eats the snails she gets, but she overfed Gary constantly and when Gary realizes this, he bails.

Movie Characters

    King Neptune 
Voiced by: Jeffrey Tambor

The ruler of the sea, whose crown is his prize possession and holds his symbol of authority over all his undersea kingdom. It should be noted that he is not the same King Neptune that appears in the series, and is exclusive to the movie.

  • Absurdly Bright Light: His bald head.
  • Bald of Awesome: So awesome that it blinds people.
  • Berserk Button: Don't touch his crown.
  • The Caligula: Not above using harsh punishments for the most petty of reasons. If it weren't for Mindy's intervention, he would have sentenced the royal crown polisher to 20 years in the dungeon for touching his crown, the job that he was hired to do.
  • Divergent Character Evolution: As noted, he's a wholly different incarnation of King Neptune than the one in the main series.
  • Fiery Red Head
  • The Gods Must Be Lazy: Couldn't concern himself with the fact that Plankton was enslaving all of Bikini Bottom. But his crown and bald head are Serious Business
  • Hair-Trigger Temper
  • Insistent Terminology: He insists his bald head is "thinning!"
  • Jerkass Gods: More so than his series counterpart - he was going to imprison someone who touched his crown for 20 years. The kicker? Said person was the royal crown polisher. Also, according to Mindy, he can barely go one day without trying to execute someone.
  • Jerk with a Heart of Gold: At the end of the movie, King Neptune gets an aesop on how important it is to have love and compassion when you're in a position of leadership. He also apologizes to Mr. Krabs for freezing him and praises SpongeBob.
  • Kill It with Fire: Probably his favorite method of solving things.
  • Large And In Charge: Towers over just about everyone and he is the king of the sea.
  • Precision F-Strike: The only character in the movie to use a swear word: damning.
  • Redhead In Green: He has red hair and green skin.

Voiced by: Alec Baldwin

A hitman hired by Plankton to make sure that SpongeBob and Patrick never make it to Shell City. He is a living example of the movie's Darker and Edgier tone.

  • Always a Bigger Fish: Gets stomped on by the Cyclops when he, too, himself was about to stomp on Spongebob and Patrick.
  • Ax-Crazy: He gleefully admits that he loves his job - which involves killing people.
  • Badass: He makes short work of the owner of the Thug Tug.
  • Cool Bike
  • Cool Hat
  • Curb-Stomp Battle: Easily punches the toughest looking guy in the Bad-Guy Bar to his death.
  • Dark Is Evil
  • Death Glare: His main facial expression.
  • Determinator: Even after getting squished by the Cyclops, he still follows after the sponge and sea star he was assigned to assassinate.
  • The Dragon: To Plankton.
  • Evil Feels Good: "I LOVE THIS JOB!"
  • Evil Is Bigger: While not to the extent of the ginormous Cyclops, he still towers over just about every good character who isn't King Neptune and can easily squish both Spongebob and Patrick at the same time with one foot.
  • Evil Laugh: He has two of them. One when he is alone driving his way to kill our heroes, and the second one comes as he is about to step on the main duo.
  • Faux Affably Evil: He ends up bantering with Spongebob and Patrick for a bit before trying to murder them.
  • Fluffy the Terrible: When Plankton mentions that he's a vicious killer and we first see his name, it doesn't look like he'd be threatening. Then he gets dangerous.
  • Good Scars, Evil Scars: Has an easy-to-miss scar on the side of his cheek.
  • Green And Mean: He is a green-skinned hitman.
  • Guttural Growler
  • Hell-Bent for Leather
  • Karmic Death: Implied.
  • Knife Nut: Wears a knife around his neck as a necklace and uses it once to try and stab Spongebob.
  • Knight of Cerebus: When he appears the first time, you know that the movie will be Darker and Edgier.
  • Malevolent Masked Man: He wears a red cloth mask over his nose and mouth, and combines it with Sinister Shades.
  • The Noseless: Yet he can still grow a Badass Mustache on the spot.
  • Not So Stoic: Does an Evil Laugh during his first meeting with Spongebob and Patrick after spending most of his scenes before being almost completely quiet. During his second meeting with them, he loses all stoicism and has a brief Villainous Breakdown.
  • Not Quite Dead: The Cyclops stepping on him does not kill him, as he returns riding on "bigger boot". However, he's not seen again after colliding with something and falling off the back of David Hasselhoff.
  • Offscreen Teleportation: He is somehow able to get from one of David Hasselhoff's legs to the other in no time after Spongebob made a dramatic jump to the other leg.
  • Professional Killer: He is, after all, a hitman.
  • Psycho for Hire
  • Sadist: He seems to take great pride in finishing out his assassinations.
  • Saying Too Much: Lampshaded when he accidentally slips that Plankton stole Neptune's crown. Subverted because Mindy had already told SpongeBob and Patrick Plankton stole Neptune's Crown and had become The Evil Overlord of Bikini Bottom. The only thing they didn't know was that Plankton hired Dennis to not only kill them, but to dispense some Laser-Guided Karma by stepping on them, which regularly happens to Plankton.
  • Scarily Competent Tracker: He, among other things, deduces SpongeBob and Patrick were at the Thug Tug from nothing more than a small puddle of bubble fluid.
  • See You in Hell: "See you later, fools!" However it is hard to tell whether he means this or he is just being sarcastic as he is about to kill our heroes.
  • Sinister Shades: When he is first introduced, he inspects a sesame seed by taking off his shades only to reveal another pair underneath.
  • Slasher Smile: He has one throughout his second fight with the main duo.
  • The Sociopath: As befitting of a Professional Killer.
  • Testosterone Poisoning: He can grow a mustache on the spot.
  • Tom the Dark Lord: Dennis isn't exactly the first name to come to mind when you see an insane and merciless hitman.
  • Tranquil Fury: At least until his second meeting with the main duo.
  • Underestimating Badassery: The hillbilly brothers, bar thugs, and Spongebob and Patrick should have known better than to mess with this guy.
  • Vile Villain, Saccharine Show: He's one of the only villains concerned with actually offing a character, and he comes pretty close.
  • Villainous Breakdown: He is pretty calm and levelheaded until Spongebob accidentally blows bubbles into his eyes, almost blinding him. After this moment, he starts yelling and decides right then and there that he will kill the main duo without hesitation.
  • You Got Guts: "You got guts, kid. Too bad I'm gonna rip 'em out of ya."
  • You Won't Feel a Thing: Subverted.
    Dennis: Don't worry, this will only hurt a lot!


A friendly mermaid who does her best to assist SpongeBob and Patrick in their quest to Shell City. She disproves of her father's method of ruling with an iron fist, and wishes he would use a little love and compassion. She is also the target of Patrick's affections.

    The Cyclops 
Voiced by: Neil Ross (Uncredited as the Live Action Role)

The guardian of Shell City, who is actually a man in a diver suit that he never takes off.

  • Always a Bigger Fish: Stomps Dennis when he is first introduced.
  • Cyclops: Well, technically, thanks to his helmet.
  • Evil Is Bigger: He is the biggest villain in the movie and is only matched by David Hasselhoff in shear size since they are both humans.
  • Evil Laugh: The only sound he makes.
  • The Faceless: His helmet doesn't show any facial features.
  • Greater Scope Villain: His only role in Plankton's scheme is owning the gift shop that buys King Neptune's crown, and yet he's arguably far worse than Plankton.
  • Humans Are Cthulhu: To the audience, he's just a guy in an old-fashioned diving suit. To the characters, he's an incomprehensible monster defined by his unnaturalness and willingness to kill sea creatures.
  • Knight of Cerebus: He only appears for a few minutes, but those minutes are probably the darkest minutes in the whole movie, maybe even the series.
  • Laser-Guided Karma: He ends up being attacked by the sea creatures he turned into marine gifts and suntries.
  • Nice Job Fixing It, Villain: If the Cyclops never found and captured our two heroes, they would have never gotten to Shell City in time before the deadline.
  • Obliviously Evil: The Cyclops isn't aware that he is murdering a bunch of sentient underwater creatures. He learns this the hard way when all the sea creatures come back to life and get their revenge against him.
  • Oh Crap!: His reaction when all the sea creatures he killed come back to life.
    "Uh, oh."
  • Punch Clock Villain: The Cyclops is just some guy dressed up in a divers suit who goes out and fishes out for sea creatures to dry and sell as "smelly nicknacks." Although he seems to enjoy capturing and murdering sentient sea creatures a little too much, he does seem to be a normal guy off the job as seen when he goes to the bathroom while humming and carrying a book to read along with him.
  • Sickly Green Glow: All we see through the window of his helmet is a green light, which makes him all the scarier and less human.
  • Vile Villain, Saccharine Show: Remember how Dennis came close to killing Spongebob and Patrick? This guy actually succeeds. Sure, they get better, but even so...

    King Neptune's Squire 
Voiced by: Carlos Alazraqui

King Neptune's Squire, who accompanies Neptune pretty much wherever he goes, and must obey his every command.

    Burger-Beard the Pirate 
Portrayed by: Antonio Banderas

The main antagonist of The SpongeBob Movie: Sponge Out of Water, a pirate who seeks the Krabby Patty secret formula.

  • Badass: Retrieves a magical book from an island so effortlessly that he literally danced through the booby traps guarding it and toyed with the animated skeleton that tries to take it back during their fight.
  • Badass Normal: Manages to put up a winning battle against SpongeBob and his friends after they gain superpowers while being just an ordinary human.
  • Big Bad: Of the second movie.
  • Captain Colorbeard: Burger-Beard
  • Cool Loser: In spite of the fact that he's pretty much an outcast that was clearly Born in the Wrong Century, Burger-Beard owns an awesome-looking pirate ship, which is pimped-out with wheels (Stickybeard take note) and a ton of cannons on it.
  • Cut Lex Luthor a Check: Played With. The first thing he does once he gets the magical book is steal the Krabby Patty recipe so he can make money off of it rather than just make himself rich. Possibly justified by the fact that it is implied that the book is limited to influencing what has already been written in it, meaning Burger Beard can't do anything directly for himself with it.
  • Graceful Loser: In the end, he takes his defeat in stride.
  • Large Ham: You can clearly tell Antonio Banderas was having one heck of a great time.
  • Pet the Dog: Sings the Spongebob theme song with the seagulls at the end of the movie.
  • A Pirate 400 Years Too Late: The live-action parts of the movie are set in a modern, United States coast town, and he clearly doesn't belong. In fact, his pirate ship has wheels on it. And an "Auto-Pirate".

    Bubbles the Dolphin 
Voiced by: Matt Berry

  • And I Must Scream: He reveals that he hated his job as The Watcher for this reason, as he had been bound by duty to watch the cosmos for eons.
  • Bald of Awesome: When we first see him it is from the back giving him the appearance of a bald man. Being a dolphin, this applies anyways.
  • Fluffy the Terrible: While he doesn't look terrifying he has immense powers and can shoot lasers from his blowhole.
  • Heel-Face Turn: Goes from trying to kill Spongebob to helping him.
  • Heroic Dolphin: gives the main characters the ability to breathe air.
  • Furry Reminder: constantly and involuntarily makes dolphin whistling noises.
  • Large Ham: He's played by Matt Berry.
  • Space Whale: Arguably. He can travel through space.
  • Stop Motion: How he's animated
  • Toilet Paper Trail: Has this after he leaves the restroom.
  • The Watcher: He's a parody of Uatu from Marvel Comics. However he loses this job.
