Pedro is a sailor who served aboard the merchant-ship, the Karaboudjan.
He is depicted only in The Crab with the Golden Claws bringing Tintin imprisoned in one of the cargo holds of the Karaboudjan food, unintentionally allowing Tintin to free himself and able to restrain Pedro in his place. Tintin was also able to acquire a gun from him as a result of this. Once he reveals what happened, the ship's first-mate, Allan Thompson, is furious with him and knocks him to the ground. In the animated television episode of The Crab with the Golden Claws, Pedro is one of the thugs who kidnapped Bunji Kuraki from outside Tintin's apartment on Labrador Road along side his fellow crew members, Tom and Jumbo.
