The Flying Dutchman is the recurring antagonist from SpongeBob SquarePants, and a powerful ghost who haunts the ocean named after the legendary ghost ship of the same name. He is of enormous size compared to the other characters and captains a floating ghost ship with a green glow similar to his own, of which he appears to be the sole permanent crew member. He appears to be mainly interested in "scaring" undersea creatures rather than actually causing serious harm.
