Pirate Robot acts like a stereotypical pirate. He frequently uses pirate jargon, though with a robot-related spin on the usual phrases (for example, he says "shiver me circuits" or "shiver me screwdrivers" rather than "shiver me timbers").

Like pirates, he is interested in finding treasures. Despite being created by Romeo, he has no loyalty towards his creator and ditched him quickly after his creation.

He is on friendlier terms with the PJ Masks than most villains, especially Owlette
