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, immature, fun-loving, and hyperactive person with a happy-go-lucky personality.
 * 2) He is extremely determined and will often stop at nothing to accomplish a task.
 * 3) 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.
 * 4) He is very hard-working, enthusiastically working at his seemingly awful, low-paying job.
 * 5) 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"
 * 6) He is always ready for everything and anything.
 * 7) His iconic laugh.
 * 8) As mentioned above, Tom Kenny voices him excellently.
 * 9) He is mostly positive.
 * 10) As his catchphrase goes, he is always ready for everything and anything.
 * 11) 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 and in Seasons 6-8 he became 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) He's at his absolute worst in the episode "A Pal for Gary", as he was entirely oblivious to the fact that Puffy Fluffy was trying to kill Gary, and he did not show any gratitude for Gary saving him.
 * 8) While iconic, his laugh can come off as annoying to some.
 * 9) His character design in Season 6 is arguably his worst one yet.

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