Squidward J. Q. Tentacles

Squidward's personality is grumpy, hot-tempered, selfish, nasty, unfriendly, and of course, miserable. In spite of this, he is still one of the most intelligent characters, and out of the ten major characters, he can be categorized as the most educated one, along with Sandy Cheeks (Carolyn Lawrence), Plankton (Douglas Lawrence), and Gary the Snail. He has a sarcastic attitude and sees others as uncivilized morons, while failing to accept his own personal shortcomings. Squidward sees himself as misunderstood and unappreciated, blaming society for his failures.
