The SpongeBob SquarePants series is never short of exciting villains whose evil actions have created a profound impact in the life of our favorite protagonist.

Who is on your top list of SpongeBob evil characters? Here are our top eight (8) SpongeBob Squarepants villains in the entire series.
Plankton
His full name is Sheldon J. Plankton, and he is one of the main SpongeBob super villains of the animated comedy television series SpongeBob SquarePants.
Plankton persistently plots to steal the Krabby Patty formula together with his aware computer wife, Karen.
They both run the profitless restaurant with the name Chum Bucket. His restaurant is located just across Krusty Krab. Though he is the smallest character in the series, it doesn’t stop him from dreaming of stealing the formula to attain world domination.
Man Ray
To restrain his fury, Man Ray has to be kept frozen in Tartar Sauce until he met SpongeBob and Patrick, who freed him out of deception. He is considered one of the most challenging enemies of Mermaid Man and Barnacle Boy.

Aquaman’s archenemy, Black Manta, inspires man Ray. He possesses a variety of weapons and presents an ominous threat to both Mermaid Man and SpongeBob.
Dennis
He is an evil assassin that Plankton hired to rid of SpongeBob SquarePants and Patrick Star, who both embarked on a journey to prevent Eugene H. Krabs’ wrongful execution.

Dennis is a strong villain who likes to rip people’s faces. He was almost successful in killing SpongeBob and Patrick; if only the Cyclops didn’t stomp him.
Flying Dutchman
The Dutchman is a reappearing character in the show whose ghostly presence terrifies Bikini Bottom. He glows in green and wears a pirate hat and a handbag with a mark that says, “soul.”

The Flying Dutchman continues to spook the seven seas for revenge on people who made him a dummy mannequin when he died. He is powerful enough that he can change shape and even warp reality causing terror that’s beyond imagining.
Cyclops
Cyclops is a human hardhat diver who captures sea creatures to sell in a gift shop in Shell City. He is one of the cruelest villains that SpongeBob encountered, and he seems to enjoy hurting animals. For some reason, he never takes off his scuba attire, even on land.

Flats the Flounder
The flounder fish is a sadistic bully who can not reciprocate SpongeBob’s friendship but tortures him instead. He appeared in season 3 as SpongeBob’s classmate in Mrs. Puff’s Boating School.

Flats the Flounder can torture SpongeBob psychologically as he continuously announces that he wants to kick his butt. Flounder can not hurt SpongeBob physically because he’s a sponge.
Dirty Bubble
He is one of Mermaid Man and Barnacle Boy’s powerful enemies, along with Man Ray.
Dirty Bubble is a giant, transparent, brown bubble that confidently proclaimed himself as a supervillain in Bikini Bottom. His power allows him to trap and incapacitate victims inside his bubble.

Fortunately, he can be easily blown out with sharp objects.
Tattletale Strangler
The Tattletale Strangler is an army green fish with distinctive brow, brown hair, and teeth as sharp as a shark’s. He is a well-known criminal that even the bravest fish in Bikini Bottom fears him.

Breaking the law is his favorite pastime, and he would not think twice about strangling his victims.
