## His Evil Ranking

### What Makes Him Heinous?

* Attempts to run Mr. Krabs out of business by stealing the Krabby Patty secret formula.
* In his first appearance, he takes control of SpongeBob's brain so that he can steal a Krabby Patty and bring it back to the Chum Bucket. SpongeBob was aware during the process.
* Tries to turn the beach into the new site for "The Chum Bucket Mega".
* During the Frycook Games, both he and Mr. Krabs force SpongeBob and Patrick to fight each other.
* Set up a race as a ruse so that he could steal the secret formula. The temperatures during the race were life-threateningly low and he even put Karen, his own wife, at risk. It's also shown that he didn't care that she would possibly die. He later tries to fry SpongeBob and his friends to death, while not even caring that he almost killed Karen as well.
* Attempted to kill Mr. Krabs and SpongeBob numerous times.
* Cheated in a game of cards so he could have SpongeBob working for him. He later forced SpongeBob to make a Krabby Patty by threatening to put his brain inside a robot duplicate of himself, which he succeeded in. However, SpongeBob still disobeyed Plankton after this.
* Stole King Neptune's crown and framed Mr. Krabs in the process, gleefully watching him about to be executed for it despite their past friendship.
* To take out SpongeBob and Patrick, he hires a mercenary by the name of Dennis.
* Mind-controlled and enslaved everybody in Bikini Bottom after Squidward found out he gained the secret Krabby Patty formula, all without any break at all and forcing them to do labour constantly.
* Mind controlled Neptune as a ploy to take over the seas for himself and enslave everyone.
* In "Chum Caverns", he used a whip to force cave dwellers to work at the Chum Caverns.
* Enslaved countless jellyfish and turned Jellyfish Fields into a polluted wasteland.
* In "Fear of a Patty", he makes the Chum Bucket open 23 hours a day so that the Krusty Krab is open 24 hours in a bid to tire out SpongeBob. He then orders 10,000 Krabby Patties under a fake name to drive SpongeBob to exhaustion, causing him to hallucinate giant Krabby Patties, then impersonates a psychologist to get the Krabby Patty formula.
* In "Someone's in the Kitchen with Sandy", he stole Sandy's fur to use it as a disguise for stealing the secret formula, which ended up Sandy got arrested for public nudity without so much as a fair trial in the end of the episode.
* In "Spongicus", he tries to get Patrick mauled and possibly killed by a sea lion. He also prevents his customers from leaving unless they buy chum.
* In “Greasy Buffoons”, he and Mr. Krabs each sold their customers bowls of grease and lied to them, telling them it was soup. They both got a bunch of their customers sick all just for business competition.
* In "Free Samples", he deliberately poisoned people by giving away fake Krabby Patties so he could frame Mr. Krabs.
* In "It's a SpongeBob Christmas!", he infected the entire Bikini Bottom with a virus called Jerktonium, which makes people mean against their will so he can get the formula from Santa. When the virus didn't work on SpongeBob due to being extremely kind and innocent, Plankton sent a robot clone of him to make SpongeBob look naughty as well.
* Cloned SpongeBob so that he could steal the secret formula.
* In "SpongeBob's Last Stand", he created a highway while destroying Jellyfish Fields. Besides the fact that it harms nature, jellyfish also started destroying Bikini Bottom as revenge and to live here. Plankton didn't know about this, but he didn't care and try to stop removing the highway.
* Showed no care for his son, Chip, and convinced him to run away, which ultimately backfired. However, he later regretted his decision and began to care for Chip.
* Even though he had a genuinely awful and sympathetic past of being bullied at school for being very intelligent, this excuse becomes extremely petty to justify his actions.

### What Makes Him Irregular?

* He genuinely cares for his wife, Karen, his son, Chip, and his pet dog Spot.
* He did many heroic actions. Despite their rivalry, there are moments where both he and Krabs have to team up and work together. Sometimes, he also aids the main characters, such as in Band Geeks where he's among the characters that SpongeBob rallies to save Squidward's performance.
* He is pretty much never taken seriously as a villain. Nearly every episode he's in has him be played for laughs and while in the first film he was more taken seriously than usual, he still had some moments where he was played for laughs such as two times where SpongeBob stepped on him and his defeat.
* He is genuinely affable to others generally and has many pet the dog moments.
* He has shown kindess to Spongebob at times.
* He has insecurities as all he really wants in a majority of episodes is to be successful and loved.
* He has standards like being disgusted with Mr. Krabs, saying stuff such as "And I thought I was evil!".

## Trivia

* The original plan was to end the *SpongeBob* TV Show after the first movie from 2004, but the huge success and popularity of the film caused the series to keep going. If the show had stopped after the movie, Plankton wouldn't have been Irregularly Heinous, due to having far less preventions at the time, and would've instead qualified as Almost Pure Evil.
