Jellien leader
The Jellien leader was an alien and jellyfish-like monster who was the main antagonist of the episode "Planet of the Jellyfish."
It was the leader of the alien jellyfish known as Jelliens and almost succeeded in replacing everyone in Bikini Bottom with Jelliens until Sandy and SpongeBob showed up. He was evil as this was his goal as well as all the other jelliens goals.
Description
The Jellien leader looks like a giant, light green jellyfish with shiny black eyes on snail-like stalks. Similar eyes are present on its Jellien minions and clones. Its internal organs - a brain and what appears to be two orange crusty hearts - which jellyfish lack, can be seen through its transparent body. It has a huge mouth located on the lower part of its body and 15 squirmy legs.
It appears that the Jelliens' species has a matriarchal system, as the leader serves as Alpha/Queen for the Jelliens within the hive. The Jelliens that it creates serve as drones/scouts, while Jellien Clones serve as some sort of soldier to defend its lair. The Jellien's weakness is mayonnaise which they can't stand due to the fact that it gets rid of them.
Abilities and talents
The Jellien leader has the ability to create Jelliens by using DNA from a jellyfish that it consumes. It also has telepathic connection with the rest of the Jelliens, in which as it died, the rest of the Jelliens would die along with it.
Role in series
"Planet of the Jellyfish"
The Jellien leader is first seen in a strange cave in Jellyfish Fields, where it captures and swallows a jellyfish, and produces a large amount of Jelliens. It then tells the newly made Jelliens to eat everyone in Bikini Bottom, replace them with Jellien Clones, and take away the real citizens. Near the end of the episode, the Overlord somehow ends up in the Krusty Krab, where it holds everyone captive in pods inside the freezer.
When SpongeBob squirts mayonnaise on it, it melts away along with all the other clones. After it and the Jellien clones were melted, the remains were used for Relish Patties.
