Sheldon J. Plankton

Sheldon J. Plankton (Or commonly known as Plankton), born November 30, 1942, is the main antagonist of the hit Nickelodeon animated series, SpongeBob Squarepants.

He is voiced by Mr. Lawrence.

Why He Steals The Krabby Patty Secret Formula (Why He Rocks)

 * 1) He is one of the funniest Nicktoons TV villains ever created, just like another great villain that isn't from Nickelodeon.
 * 2) Memorable quotes such as "I went to college!"
 * 3) Unlike Mr. Krabs, all that Plankton wants is to have his own restaurant cares for his own customers, even if he tries to steal Mr. Krabs's Secret Formula. Although in some occasions, he wants to rule the world, considering he embraces evil.
 * 4) Plankton is very experienced with science and technology.
 * 5) In the episode F.U.N., he and SpongeBob got along well as well as the Sponge Out Of Water movie.
 * 6) Plankton acts as the deuteragonist of SpongeBob: Out of the Water, which is showing that he wants to help.
 * 7) When having his restaurant going in business, he doesn't care about money, he cares about the customers unlike his arch-enemy Mr. Krabs.
 * 8) He had shown to have good chemistry with Sandy in the episode "Perfect Chemistry".
 * 9) When the show declined between seasons 6-8, he and Gary the Snail were the most likable and least flanderized of the main cast.
 * 10) Plankton is quite a wonderful father at times. He was courageous when attempting to save his son Chip II.
 * 11) Although he embraces being evil and selfish, he does posses much better personality traits than Mr. Krabs. He values the well-being of those he befriends or in relationship, such as his wife Karen, his pet Spot, and even SpongeBob of all people. He is even willing to help SpongeBob and his friends geniuinely when not having a hidden agenda (usually stealing the formula).
 * 12) He can be a menacing and intimidating villain in occasions such as the first movie, where he succesfully takes over Bikini Bottom, or his debut appearance with his controlling of SpongeBob.
 * 13) Plankton's miniscule appearance coupled with his Napoleon complex makes for some recurring hilarious slapstick gags, such as being stomped by people like a bug.
 * 14) He often has quite a snarky attitude and his remarks can be funny enough.
 * 15) His first name, Sheldon, can be hilarious, in "Plankton's Army".
 * 16) His screams, provided by Mr. Lawrence, are incredibly funny to hear.
 * 17) Memorable dialogue and quotes:
 * 18) * "I went to college!"
 * 19) * "Not if I shift to maximum overdrive!"
 * 20) ** "I knew I should've added the turbo."
 * 21) * "Arggh! It's not worth it! (calmly) Goodbye everyone, I'll remember you all in therapy."
 * 22) * "You'll never get what you want if you let people step all over you."
 * 23) * Customer: "You think this is funny?"
 * 24) ** Plankton: "In a cosmic sort of way, yes."
 * 25) ** Customer: "Well Mr. Funny man, is this how you get your sick kicks!?"
 * 26) ** Plankton: "What? It's just an ordinary Krabby- Oh my goodness! Squidward!"
 * 27) * "Enjoy while it lasts, Mr. Krabs. Soon enough, I'll have the formula, then everyone will eat at the Chum Bucket, AND I WILL RULE THE WORLD!"

Bad Qualities

 * 1) As said above, he is often mean-spirited and obnoxious towards the kindness of others. Again, because he is evil, he's supposed to be that way.
 * 2) * He was very unlikable in "Someone's in the Kitchen with Sandy", because he robbed, humiliated, and got Sandy arrested in that episode.
 * 3) *In "Welcome to the Chum Bucket", he neglected SpongeBob's feelings and fails to show him compassion and understanding so he can make a Krabby Patty, meaning he's not only mean-spirited, he was also stupid.
 * 4) * In Karen 2.0, He heartlessly shuts off Karen's brain, who has been nothing but a good wife to Plankton, to be replaced over Karen 2 and trashing her, essentially  killing Karen or at least, putting her permanently to sleep. 
 * 5) He is at times selfish and he tried to get rid of his son. He had told him to run away.
 * 6) His obsession with stealing the secret formula from Krabs often leads to a strained relationship with his wife, Karen, who usually tolerates his repetitive ambitions.
 * 7) Much like Wile E. Coyote: He can be quite the punching bag in a predictably incompetent fashion when he typically fails at his single-minded schemes, along with the constant running gag of Plankton's sheer ineptitude with his rivalry against The Krusty Krab does get a bit stale towards viewers. Not to mention that even after seasons 6 to 8, he too can still have bad episodes that focus on him suffering in a miserable state of mind, and much to the point you can sometimes sympathize with him in a pitiful manner.
 * 8) *He almost killed himself in the infamous Season 7 episode "One Coarse Meal" because of his fear of whales and all because of Mr. Krabs maliciously making him incredibly depressed and fatalistic. Thankfully, he overcame his fear of whales in later episodes like "Patnocchio" for example.
 * 9) * In "Plankton's Regular", when he finally got a customer who likes his chum and was happy about his achievements, he is yet pointlessly suffering and being completely miserable because of Krabs and SpongeBob themselves (the former out of petty jealousy and the latter naively thinking that he was making another 'villainous' plan of his).
 * 10) His short temper often leads to Karen's frustration and his failings.
 * 11) He can be childish and whiny at times.

Trivia

 * In a theory based on SpongeBob and his friends representing "The 7 Deadly Sins", Plankton is considered to be the "Envy" as several examples were shown in many episodes that always shows how determined Plankton was with getting the better of Krabs for his success at The Krusty Krab.
 * He was born on November 30, 1942 making him a Sagittarius.
