First Mate Pablo is a pirate played by Pablo.
He was initially Captain Blackmoose's right-hand man until he manipulated the crew into turning on Blackmoose. Just as he was about to touch the scepter, he and the crew was tackled by Blackmoose, Uniqua, Thomas, Sophie, and Andrew and Austin touched the magic scepter and became king. When King Austin demanded to know who committed mutiny on Blackmoose. Having been defeated, Pablo confessed to orchestrating a mutiny on Blackmoose and he revealed the real truth: he was holding Blackmoose responsible for the loss of Pablo's leg during a terrible storm (which explains why he has a peg leg). When King Austin asked Pablo why he wouldn't forgive Blackmoose when he should have, Pablo explained that Blackmoose didn't listen to his warnings because he knew the storm was in their path during one of the journeys. This upset Blackmoose so much that he berated Pablo for not being clear on why they shouldn't go that way. This prompted Pablo to apologize to Blackmoose for not filling in the details and for being a grudger. He acts as the true antagonist of the episode The Pirate King.
First Mate Pablo is mostly of a blue color.
