SpongeBob SquarePants (seasons 1-6A, 8-present)

SpongeBob SquarePants is the main character from the series of the same name. He is voiced by Tom Kenny, who is also responsible for voicing other famous characters including the Ice King.

Why He Rocks

 * 1) He is a wonderfully optimistic, abnormal, mature, fun-loving, and hyperactive person with a happy-go-lucky personality.
 * 2) Like Patrick Star, he was responsible for creating such memetic material with some expressions he's made from the series to the 2004 movie and such memeable scenes his existence has made with many worldwide. And also had tons of timeless, hilarious scenes.
 * 3) * Speaking of which, Spongebob can seem more intelligent than Patrick in spite of his naivete or his loony if jolly behavior.
 * 4) With that said, he is greatly animated.
 * 5) He has a cute character design like many characters drawn by Hillenburg.
 * 6) He is extremely determined and will often stop at nothing to accomplish a task.
 * 7) He is very kind. He is a good owner to Gary (most of the time), a good friend to Patrick, Sandy, and is nice to Squidward even though he isn't nice to him (a typicial "Love Thy Neighbour" message).
 * 8) He is very hard-working, enthusiastically working at his seemingly awful, low-paying job.
 * 9) He comes up with good songs like "Who Am I?" and "The C-A-M-P-F-I-R-E S-O-N-G Song"
 * 10) He is always ready for everything and anything.
 * 11) His iconic laugh.
 * 12) As mentioned above, Tom Kenny voices him excellently.
 * 13) He is mostly positive.
 * 14) As his catchphrase goes, he is always ready for everything and anything.
 * 15) He is the titular protagonist of two incredible animated films that combines live-action, surreal humor, and compelling themes rolled up in an adventurous, emotional odyssey.

Bad Qualities

 * 1) He was hit hard with flanderization from Seasons 6-8 as he became an very annoying, unlikable and an immature idiot.
 * 2) He can be annoying sometimes even in the seasons where he isn't flanderized.
 * 3) He's incredibly naive. For example, he thinks that Mr. Krabs is a generous, non-cheap and big-hearted person when he's really the exact opposite.
 * 4) He can be a Butt-Monkey type character (a character that gets abused for no reason).
 * 5) His high-pitched voice from the first movie to Season 7 is kind of annoying.
 * 6) He is somewhat dramatic to the people who are kind to him: for example, to the mailfish.
 * 7) In "To Love a Patty", he gruesomely murdered a bunch of scallops only because the scallops were trying to eat the Krabby Patty he loved despite the fact that he himself raised one in "Rock-A-Bye Bivalve" and the fact he has a pet scallop named Shelly in a few episodes, making this hypocritical.
 * 8) While iconic, his laugh can come off as annoying to some.
 * 9) His character design in Season 6 and Season 8 is arguably his worst one yet.

Trivia

 * His show is widely considered to be one of the best and most popular cartoons out there.
 * He was designed by the late marine biologist and teacher, Stephen Hillenburg (rest in peace).
 * Hillenburg based SpongeBob on Bob the Sponge, a character he had created for his educational book "The Intertidal Zone" in the late 1980s.
