Like most jellyfish, his tentacles are electric. Unlike most other jellyfish, he can shoot electricity.

He is the only known jellyfish who is capable of speech, as shown when he angrily says Kevin C. Cucumber's name or admires a bubble pie.

I'm Your Biggest Fanatic 103

He seems to have experience in football since he rams a cave while wearing a football helmet and jersey.

Personality

He appears to be nice to anyone he meets or encounters unless they trick him.

He falls in love with the queen jellyfish robot that Kevin made.

He also has an unexplained grudge against Kevin, as he tried to zap him when seeing him.

He seems to have a fondness for pie as shown when he is delighted by SpongeBob making a pie out of bubbles.

Occupation

He is the king of all of the jellyfish.

Role in episode

He appears after Kevin C. Cucumber tries to trick SpongeBob into falling into a hole with a queen jellyfish ship. SpongeBob and Kevin are shocked to see him in person, as they identified who he is. The king jellyfish takes notice of them and thinks that the ship is the real queen jellyfish and he chases it until he hits a billboard for Kevin's Ointment. It breaks and the king jellyfish realizes that it is a fake.

He then notices Kevin and gets mad at seeing him. The king jellyfish chases the Jellyspotters and SpongeBob into a cave. He notices that the group has gone into a cave; he puts on a football uniform and starts hitting the cave. Eventually, he stops and Kevin sends an anchovy, who, at first, says it is okay to leave, but then gets electrocuted and returns.

After the Jellyspotters give up, SpongeBob walks out. The king jellyfish gets ready to electrocute SpongeBob, who takes out a bottle of bubble soap and blows a bubble that looks like a pie. The king jellyfish cheerfully takes the bubble pie and leaves.

Role in video games

Battle for Bikini Bottom

King jellyfish

Squidward gets electrocuted by some jellyfish and SpongeBob says that the only way to cure severe jellyfish wounds is to get some king jellyfish jelly. Squidward says that SpongeBob should scale Spork Mountain and fight the king jellyfish. SpongeBob finds the king jellyfish singing in a giant shower at the top of the mountain, and the king jellyfish is angry at him for interrupting his shower. SpongeBob fights him and wins; the king jellyfish gives SpongeBob a jar of his jelly and leaves.

The Yellow Avenger

He is in the Kelp Forest being attacked by three little Dirty Bubbles. The Yellow Avenger has to bounce on nearby plants to reach the king and then must throw waterballs in order to knock the bubbles off of him. After hitting him with three water-balls, he leaves and gives the Yellow Avenger access to the forest's clearing.

Battle for Bikini Bottom - Rehydrated

King Jellyfish Rehydrated

He reappears in this game, reprising his role as the mini-boss at the end of Jellyfish Fields. The king jellyfish has also been redesigned; he appears slightly translucent, closer to his appearance in "I'm Your Biggest Fanatic."

Relationships

Relationship with SpongeBob

In the video game Battle for Bikini Bottom and its remake, SpongeBob accidentally disturbs the king jellyfish's shower during a request to obtain some jelly. He seems to have this anger in "I'm Your Biggest Fanatic." SpongeBob gives him a pie and they are thus on good terms.

Relationship with Kevin C. Cucumber

In "I'm Your Biggest Fanatic," it appears that the king jellyfish is familiar with Kevin as he recognizes him and gets angry with him for something that he may have done to him. He then chases him, SpongeBob, and the other Jellyspotters.

Etymology

  • King Jellyfish's Latin name is Cnidaria Rex. Cnidaria is the phylum of mostly aquatic marine invertebrates that have cnidocyte, a specialized stinging cell found in creatures such as jellyfish and sea anemone. Rex is Latin for the king.

Trivia

  • Unlike other jellyfish, he actually talks, which can be heard briefly when Kevin and his members go inside the cave.
