The captain of Peary is the commander of the São Rico vessel the Peary who makes his only appearance in The Shooting Star. His name is never mentioned and is only mentioned as captain by his first mate Frank.
He was hired by Mr. Bohlwinkel in São Rico to find and confiscating the meteorite that had fallen down near the North Pole before the Aurora Expedition. However unlike his financier, and the rest of the crew, he seems to be a much more honest and lawful man as he stops his first mate Frank from shooting Tintin down to prevent him to land on the meteorite and place the Aurora Expeditions flag on its highest peak before his own men even if it costs them the victory. He even calls Frank crazy for entering the idea. This action makes him to a not complete villain. After the defeat, he left with his ship and the crew and returned to São Rico.
