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 very optimistic.
 * 2) He is very kind. He is a good owner to Gary (most of the time), a good friend to Patrick, and is nice to Squidward even though he isn't nice to him.
 * 3) He is very hard-working, enthusiastically working at his seemingly awful, low-paying job.
 * 4) He comes up with good songs like "Who Am I?" and "The C-A-M-P-F-I-R-E Song"
 * 5) He is always ready for everything and anything.
 * 6) As mentioned above, Tom Kenny voices him excellently.

Bad Qualities

 * 1) He can be an idiot and a jerk in seasons 6-8.
 * 2) He can be annoying sometimes even in the good seasons.
 * 3) He's incredibly naive. Like he think Mr. Krabs is a generous, non-cheap, and big-hearted person, even though he's the exact opposite.
