Mr. Krabs (seasons 6-10)

Eugene Harold Krabs, commonly refered as Mr. Krabs, is one of the ten main characters in the Nickelodeon animated series, mh:besttvshows:SpongeBob SquarePants. He is the money-obsessed founder of the Krusty Krab and the business rival of Plankton. Although he's one of the series' main protagonists, Mr. Krabs has been depicted as anti-heroic and even villainous (especially in seasons 6 and onwards), eventually going so far as to become the direct antagonist of several episodes.

Bad Qualities

 * 1) In the notorious Seasons 6 & 7, he was at his absolute worst because he got flanderized to become more and more greedy and abusive than he already was before and after these seasons. In fact, these seasons generally depict Plankton as a huge "butt-monkey" in most of the situations where Mr. Krabs is at his worst and Plankton is completely harmless.
 * 2) Like Stan Smith, the way he's written and portrayed in seasons 6-onwards is all over the place. He is supposed to be a greedy yet have a caring side, but nowadays, most of the time, commits even more crimes than Plankton does.
 * 3) He is as villainous as, if not worse than, Plankton. In the infamous Season 7 episode, "One Coarse Meal", he tortured Plankton to the point where he started feeling suicidal for fun, when in reality Plankton was hardly doing a thing. This  is considered his worst moment in the series by fans.
 * 4) He broke the law and violated workers rights countless times, such as making his employees work twenty-four hours a day once. In fact, he's broken more laws than Plankton ever has.
 * 5) *He also doesn’t always care for the health and well-being of his employees. While he lets Spongebob have a sick day when he becomes ill, an injury is a different story. The greatest example of this is “Squid Baby”, in this episode, Squidward had a brain injury that causes him to behave like an infant. He still has Squidward work despite not being able to, he also DOES NOT LISTEN to Spongebob and Patrick when they try to explain this to him..
 * 6) He pathetically makes huge molehills out of mountains for stupid reasons, such as when the Chum Bucket started getting a regular customer in "Plankton's Regular".
 * 7) Speaking of which, he hardly ever cares for other people, and he even wanted to get Squidward "out of the picture" just to sell his paintings for a higher price in "Out of the Picture". So "heroic"! Even worse, he tried to murder Squidward with a hammer. This wasn't even the only time where he considered killing his employees for money.
 * 8) He also committed animal cruelty, particularly when he used Gary as a magnet to steal cents from a local arcade game room.  In fact, he seems to casually get away with crimes throughout the series or at least not get the proper punishment for them, from imprisonment (various episodes) to trying to get Plankton to straight up kill himself ("mh:terribletvshows:One Coarse Meal") right up to downright attempted murder ("Out of the Picture").
 * 9) He sometimes gets no punishment for his actions.
 * 10) *He also once stole money from the entire city of Bikini Bottom with Spongebob’s pet Gary in episode “The Cent of Money”.
 * 11) He can be a Karma Houdini since, owing to his naivety, SpongeBob overly patronizes him like a saint, and follows his orders without question. He doesn't even stand up against his boss to stop him from furthering his schemes like he did in the early seasons.
 * 12) He has a very strict set of rules for his customers. It’s mandatory to order a side of fries, napkins and refills cost extra, and there are absolutely no freebies for anyone – royalty or not. In fact, according to Mr. Krabs, all the money brought into the Krusty Krab must be spent. Even the people who aren't hungry are dragged in and forced to order food. Sure, there's a money back guarantee, but it's so small it's almost impossible to see. No matter what it takes, Krabs will make sure that nobody even goes near his restaurant without emptying their wallets. One time, he even charged his customers $1.00 per footstep in the restaurant.
 * 13) He doesn't seem to care about the lives of his customers, as seen in "Mutiny on the Krusty", where he had his own customers pull the Krusty Krab back to Bikini Bottom while leisurely sitting on the roof with SpongeBob, laughing.
 * 14) * In "Spongebob's Place", he digs a circular trench around the Krusty Krab and places molten lava on it when the customers almost leave.
 * 15) His greed is so overblown it borders through obsession or even insanity.
 * 16) * Whenever an opportunity of profit presents itself towards him, he instantly grabs it without thought and transforms his business into whatever the opportunity is given, only to backfire at the end. Such examples are but not limited to publishing newspapers, cashing in on SpongeBob's popularity, pawning the Krusty Krab in exchange of forming a band (in which he does so through theft of other people's possessions), or even outright turn his restaurant into a prison. Often times, he changes the rules or eliminates them altogether, throwing away all moral high ground he might have.
 * 17) * He once tried to marry money while trapped in a safe, to the point that it caused him to have hallucinations.
 * 18) *He at one time had been so obsessed with a single penny in "Penny Foolish" that he believes SpongeBob picked up that he even tresspasses and breaks in his employee's house. He didn't got it out of his system despite that it was only a chewing gum (in turn a wet paper bill), as he kept digging randomly through SpongeBob's front yard just to find a penny.
 * 19) * He often puts money on a higher pedestal than even himself, making him a borderline nihilist.
 * 20) * He will commit even counterfeiting to further his desires.
 * 21) * He literally and shamelessly embraces his greed. That's the bottom line.
 * 22) Despite his genuine love for his daughter Pearl, their contrasting personalities often clash, resulting in more harm than good.
 * 23) * Due to his greedy nature, he goes to extreme lengths to please her while protecting his money, like feeding her in "Growth Sprout".
 * 24) * He often neglects his daughter's needs or wants, such as an allowance or an expensive item. Instead, he makes or comes up cheaply-made or crude substitutions to please her, often backfiring.
 * 25) * Due to his greed, again, it prevents him from being open-minded about Pearl's desires.
 * 26) * More often than not, he acts like a stereotypical "Dad thinks his kid's still a baby" kind of parent, to Pearl's own embarrassment.
 * 27) * There are times where he outright neglects her well-being, such as using Krabby Patties to make soap, which caused barnacles to appear on Pearl's face. If Krabs wants to make bars of soap instead of buying them, why can't he just use safer, more fragrant materials?
 * 28) * There's also a time where Krabs literally locks up Pearl inside his own house under Squidward's care in "Whale Watching", which is considered child abuse and illegal detention, even for a kid's cartoon.
 * 29) He can also be awful to his girlfriend, Mrs. Puff, as well. Particularly in Summer Job, where he spends the entire episode blackmailing and treating her terribly after forcing her to work at the Krusty Krab in exchange for not telling anyone about how she destroyed part of the restaurant after driving into it.
 * 30) Unlike the other characters, he has not completely redeemed himself from flanderazation, though as mentioned below, he is now more tolerable and is slowly improving.
 * 31) He acts immature, despite being 78 years old.

Good Qualities

 * 1) He didn't use to be that heartless, as he showed compassion for his employees more frequently and was a more likable/decent character in Seasons 1-5.
 * 2) His design is still good.
 * 3) Time and time again he realizes that his greed would be his own undoing, causing him to usually revert whatever alternate business he had back to where it was before. He often also realizes the error of his ways, giving away his employees for parsimonious reasons, such as when he sold SpongeBob for 62 cents, only to reject the money out of regret.
 * 4) He does possess other interests in life than money, such as doing everyday outings, but usually, his parsimony overshadows it all.
 * 5) He shows genuine friendship with other people, like SpongeBob, his old Navy mates, as well as formerly his rival Plankton.
 * 6) He usually has a good reason on why he doesn't want Plankton to take at least one Krabby Patty. Plankton is evil and wants to conquer the whole Bikini Bottom (or in Plankton's words, the world) after he runs Krabs out of business, which is his top priority. Despite his Napoleon complex, his machines potentially help him achieve his goals, as seen in the first film. But it still did not excuse all the atrocities he inflicted on his rival.
 * 7) He does show genuine affection for his mother, and his daughter Pearl, however, his parsimony results in a strained relationship with the latter.
 * 8) He occasionally apologizes for his actions, but not so much after Season 5.
 * 9) Although he still hasn't completely redeemed himself from flanderization in recent years since Season 9 unlike the rest of the SpongeBob SquarePants cast; he is now much more tolerable than he was in Seasons 6-8.
 * 10) Clancy Brown still portrays him amazingly and memorably.
 * 11) He's a decently funny character at times.
 * 12) * He also helped SpongeBob in the episode, "Shell Shocked", where he lends him his own shell to Gary after SpongeBob accidentally broke it as well as all the other shells in Angry Jack's.
 * 13) * He also taught SpongeBob how to drive in the episode, "Tutor Sauce" because the latter failed his boating school, despite that his tutoring methods are illegal. In that same episode, a rare generous side of him is shown towards his daughter Pearl, as he willingly gives his daughter Pearl some money in order for her to buy shoes.
 * 14) He sometimes has his original personality, and there are a boatload of episodes where he is likeable.

Reception
Critical reception for Mr. Krabs was intiailly positive but has been mixed as the series progressed, with most criticism directed at his parsimony and the lack of realistic consequences he faces for it.

Trivia

 * Mr. Krabs has many internet memes associated with him.
 * In a theory based on SpongeBob and his friends representing "The 7 Deadly Sins", Krabs is considered to be the "Greed" as several examples were shown in many episodes that always shows how much he loves so much for his money, even in the most ridiculous ways possible.
