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".
The Adventures of Tintin: The Secret of the Unicorn (video game) found is slightly different from his. On the way home, he is kidnapped and taken aboard the "Karaboudjan", a steam ship heading for Baghar, a city located in North Africa. Tintin escapes from his cell and meets Captain Haddock, the original captain of the ship, who has been imprisoned by Sakharine after he took over the ship and bribed Haddock's crew into working for him. Haddock helps Tintin and Snowy escape, but as they are at sea in a lifeboat, they are attacked by a seaplane sent by Sakharine. The attack fails and Tintin is able to damage the plane.
