Captain Haddock the Picaros", when Professor Calculus 'cures' him of his taste for alcohol. In the adventure "Secret of the Unicorn" (and continuing in "Red Rackham's Treasure") he and Tintin travel to find a pirate's treasure captured by his ancestor, Sir Francis Haddock (François de Hadoque in French). With newfound wealth and regaining his ancestral home Marlinspike Hall, Captain Haddock becomes a socialite; riding a horse, wearing a monocle, and sitting in a theatre box seat ("The Seven Crystal Balls"). He then evolves to become genuinely heroic, volunteering to sacrifice his life to save Tintin's own in the pivotal "Tintin in Tibet".
Snowy (character) of Captain Haddock in "The Crab with the Golden Claws". Before Haddock's appearance, Snowy was the source of dry and cynical side-commentary, which balanced out Tintin's constantly positive, optimistic perspective. When Haddock entered the series, the Captain took over the role of the cynic, and Snowy gradually shifted into a more light-hearted role, having dialog only with Tintin. Snowy is portrayed as brave and is often fearless against much larger creatures when Tintin is threatened. He repeatedly frees Tintin from captivity and saves him from dangerous situations, and will sometimes identify a villain before Tintin. His only fear is arachnophobia.
