Jellion Patrick greatly resembles the real Patrick Star except for the dark, round eyes. This is a common trait for the rest of the Jellion clones.
Jellion Patrick was created after the Evil Alien Jellyfish Overlord created a jellion after eating a jellyfish then having it eat a sleeping Patrick and then carried him away. Jellion Patrick then meets up with SpongeBob who spots that he caught a jellion thinking it was a jellyfish. Jellion Patrick then catches a whole school of jellions. He then tricks SpongeBob to give them away to his friends. After turning Squidward into a Jellion, Jellion Patrick then works at the Krusty Krab where he helps serve Krabby Patties, without the mayonnaise. He was then finally destroyed after SpongeBob sprayed him with mayonnaise when Jellion Patrick and Sandy were about to take on the Evil Alien Jellyfish Overlord.
Jellion Patrick behaves very differently from Patrick. His only course of action is to plant jellions on the heads of citizens and turn them into Jellion Clones. Like all jellions, Jellion Patrick extremely hates mayonnaise as when SpongeBob tells him that he was going to get more in the back, Jellion Patrick quickly turns his head around (with his torso still facing the grill) and loudly shouts out "NO MAYONNAISE!"
"Yes. I too have caught many jellyfish. Perhaps we shall give one to each of our friends."
