SpongeBob SquarePants (seasons 6b and 7)

SpongeBob SquarePants is the main character from the American children's animated television series of the same name. He is an optimistic yellow sea sponge who works as a fry cook and goes to a boat-driving school.

Unfortunately, he suffered from a bad case of flanderization and some character derailment in Seasons 6-8.

Bad Qualities (Seasons 6-8 only)

 * 1) He became outright annoying, troublesome and obnoxious.
 * 2) He is either too happy or too emotional in comparison to his other traits within his personality in the first three seasons, though it varies whether he was in character or not in seasons four and five.
 * 3) He tends to cry over things that aren’t a big deal at all whatsoever. Heck, not even Pearl, Mr. Krabs’ daughter, is that much of a crybaby in these seasons in comparison to the first three seasons!
 * 4) He also has the tendency to do terrible things and never gets any consequence for them, such as:
 * 5) * Digging a hole in the road to make Squidward wreck his bike (Choir Boys)
 * 6) *Being a huge stalker to Squidward and becomes obsessive towards him in some episodes (Boating Buddies) (Choir Boys) (Squid's Visit)
 * 7) * Kidnapping the townspeople by trapping them in bubbles and bringing them to his house (it makes sense in context) (Rodeo Daze)
 * 8) *Ruining Squidward's chance of joining a choir by upstaging him (Choir Boys)
 * 9) * Apparently lacking empathy
 * 10) *Laughing and making a joke about Mrs. Puff getting injured even after he crippled her for life (Demolition Doofus)
 * 11) * Causing boat wrecks (albeit unintentionally) without feeling remorse for it (Boating Buddies)
 * 12) * Scolding and blaming Gary for things he clearly didn't do and telling him "what do you have to say for yourself?" instead of thanking him when he saves his life (in the same episode, by the way; and not to mention, he also stole a pet from a store, and also ignored the pet saleswoman's warnings about Puffy Fluffy's own species getting along with other animals). (A Pal for Gary)
 * 13) *Him and Patrick framing Mermaid Man and Barnacle Boy by disguising as them and falsely arresting tons and tons of people for little to no reason (such as not feeling like finishing their food, not tying their shoes, being old etc.), including Man Ray (who hasn't done anything evil, but he got arrested just for going to the laundry shop.) (Shuffleboarding)
 * 14) *Flooded Bikini Bottom with his crybaby tears (A Day Without Tears)
 * 15) *Betrayed Plankton (One Coarse Meal)
 * 16) *Inviting Patrick Star, Sandy Cheeks, Mr. Krabs, Pearl Krabs, Plankton, Larry the Lobster, and Bikini Bottomites to go as far as tarnishing Squidward's TV show, idiotically acting like it was a playground, and not to mention; they were the ones responsible for Squidward being kicked out of his house and his own TV show shut down (Tentacle Vision)
 * 17) He can be mean-spirited at times, though not as bad as Patrick, which is a character downgrade that was unexpected, especially for SpongeBob.
 * 18) His gags have gone from funny and entertaining to irritating and unintelligent.
 * 19) His infamous and hypocritical quote from "One Coarse Meal": ("I'm sorry Plankton, but that flies in the face of my good nature.")
 * 20) He is extremely immature and never acts his age. Before flanderization, it was admittedly rare for him to act like an adult, but he still had some levels of maturity. However, during these seasons, he never does.
 * 21) His voice is annoyingly high pitched to the point where he sounded like he is on helium, possibly due to Tom Kenny’s aging.
 * 22) He has also turned into a punching bag for the writers in some episodes most notably ("Stuck in the Wringer").
 * 23) His nose is constantly drooping in these seasons like Squidward's nose, which gets pretty annoying, despite it rarely happening in previous seasons.

Good Qualities

 * 1) He occasionally has his original personality.
 * 2) He still cares about his friends, despite everything he has done.
 * 3) His voice has returned to its original pitch since Season 8.
 * 4) He spawned some post-movie memes like "Who put you on the planet?" and his mocking chicken pose.
 * 5) His design still looks cute.
 * 6) He did get karma for his actions in "Little Yellow Book" when Squidward gets his revenge on him in by reading his diary to the customers. Proving that Squidward won't let him get away with all of the wrongdoings he has done and got away with as said in WHS #3 (Even though Squidward deserved a comeuppance for that). But that still doesn't remove him from the Karma Houdini party or the Idiot Houdini party.
 * 7) He has fully gotten his original personality back in Season 9.
