SpongeBob SquarePants is the main character in the series. He lives in Bikini Bottom. He has always worked at The Krusty Krab. He goes to boating school. His house is shaped like a pineapple. SpongeBob has several friends, such as Patrick Star and Sandy Cheeks. He looks up to his boss, Mr. Krabs, and serves as Krabs's moral compass when his greed goes too far. He is blissfully unaware that several people find him annoying. This is taken to the extreme with Squidward, who despises Spongebob, although the latter considers themselves best friends.
Note: SpongeBob is the mascot for Nickelodeon since his inception in the early '00s.
- Voice Actor Bill Fagerbakke
Patrick Star is a sea star who is SpongeBob’s best friend and neighbor. He lives under a rock and favors colorful trunks(mainly green and violet) as his attire. Patrick is widely considered a moron.
- Voice Actor: Rodger Bumpass
Squidward Q. Tentacles is bald with greenish-blueish skin, a large nose, and lives in a easter island head located between SpongeBob's and Patrick's residences. He works as a cashier at the Krusty Krab, a job he despises. SpongeBob and Patrick consider Squidward their friend, but the feeling is not mutual. Squidward tends to be a downer, and is often pulled into embarrassing and awkward situations by Spongebob and Patrick.

Sandy Cheeks is a squirrel who is SpongeBob's closest friend after Patrick. She is the series' only land-based character (originally from Texas), but lives in a large underwater home known as the "Treedome", which contains a large oxygen producing oak tree and is sponsored by three primate scientists who provide her with grants so she can invent mechanical devices. She is a scientific genius, practices karate with SpongeBob, and enjoys extreme sports. The only reason she taught Spongebob karate was so she could have a punching bag, and that as was revealed in "King of Karate", when Sandy said she taught him everything he knows, she then said that wasn't much.

Eugene H. Krabs (commonly known as Mr. Krabs) is the despicable cheapskate owner and founder of the Krusty Krab. He is a red crab, though his daughter, Pearl, is a whale and they both live in an anchor. He is the employer of both SpongeBob and Squidward. Despite his attitude and love of money, he is often respected by SpongeBob while Squidward tends to loathe him. Mr. Krabs also claims to love Mrs. Puff, SpongeBob's driving school teacher but their relationship is not mentioned again. He has been to court 2 times for turning Krabby Patties to Spongy Patties which make people turn into spongy zombies in the episode "The Krusty Sponge", & the other time he went to court was when Plankton complained that he got hurt because there was a wet floor, and no wet floor sign. Plankton was never actually hurt. He will also do anything for a penny, such as rob a grave, and even sold the Krusty Krab. Most of the time he is described as cheap. He has a bad back due to sleeping on his mattress at home that has all of his money in it. A running gag through the series is that his legs and arms frequently break off.
- Voice Actor: Doug Lawrence
Sheldon J. Plankton (commonly known as Plankton)is a small green copepod who is Mr. Krabs's nemesis and the main antagonist of the series. He runs an unsuccessful restaurant called the Chum Bucket, located directly across the street from the Krusty Krab. He is married to a computer named Karen, and nearly became Mr. Krabs' stepfather in the episode "Enemy-In-Law." Also, his main goal in life is to steal the Krabby Patty secret formula and put Mr. Krabs out of business. Plankton succeeds at stealing the formula in the movie, but his goal of world domination is thwarted by SpongeBob. He only had one customer at his restaurant in "Plankton's Regular" , but it turned out that Karen was paying the man to pretend to like Plankton's chum.

Gary is SpongeBob's pet sea snail. As worms are analogous to dogs in the series, snails are to cats, and Gary vocalizes like one. He is extremely intelligent and does various chores for SpongeBob, such as making his breakfast and paying the electric bill. Once, Spongebob believed Gary favored Patrick over him, although Gary was just after the cookie in Patrick's pocket. He is occasionally shown as anthropormorphic, such as cooking, drinking coffee, reading the newspaper, etc. He is shown to be a good leader, like when in a episode, he incited a riot at a pet show where all the animals were force to wear demeaning outfits. Gary is always right and proves Spongebob wrong.
