Best : Plankton
Worst: Mrs Puff
Creepiest: Squidward
Best:Spongebob
Creepiest:Squidward
Worst:Uh...
Best: Patrick Star
Worst: Squidward Tentacles
Creepiest: Sandy Cheeks
Best: Nat Peterson. He has a job and family and hasn't done anything over the top that'd ruin the town or somebody's life. He's even thrown Plankton a bone by being his loyal customer even though he was in it for the money (which he could possibly need to help out his family). The execs at SnailPo really respect him too.
Worst: Patrick. He's demonstrated that his stupidity isn't actual stupidity so therefore anything he's done has been on purpose (Including eating Squidward's backstage pass tickets and making Spongebob think that he only had 1 copy of a rare card, only to destroy it beyond repair)
Creepiest: Spongebob. That one episode when Squidward said "What could you have possibly heard me doing" and Spongebob responded with "You breathing" is enough alone to take the creepy cake, yet I'm sure that's not the only incident.
Worst: Doodle Squidward, because he is poorly drawn by Patrick and has absolutely no effect on the series.
Creepiest: Patrick Not-Star. He's cool, but he sorta gives me the creeps...
Best: Seasons 1-3 Patrick. He has just the right amount of stupid that makes him funny.
Worst: Mr. Krabs. He goes waaaayy over the top in greediness.
Creepiest: Spongebob. I'll have to go with Zario777 on this one.
Best: SpongeBob/Season 1 Patrick Creepiest: Flying Dutchman disguises from Ghost Host Worst: ???
Best - Patrick (Season 1-5)
Worst - Pink Idiot Jerk with One Tooth (Season 7 and 8)
Creepiest - Stalker Spongebob from the modern STPs
Best- Gary. The only character who transitioned well from Pre-Movie to Post-Movie, and the only thing he says is Meow.
Worst- Officer John: He arrested SpongeBob because he wasn't invited to a party. How stupid is that.
Creepiest- I don't admit to this, but I used to be very scared of Wormy
