The Adventures of Tintin depicted as a weak and alcoholic character, but later evolves to become genuinely heroic and even a socialite after he finds a treasure from his ancestor, Sir Francis Haddock (Chevalier François de Hadoque in the original version). The Captain's coarse humanity and sarcasm act as a counterpoint to Tintin's often-implausible heroism; he is always quick with a dry comment whenever the boy reporter seems too idealistic. After he and Tintin find Red Rackham's treasure, Captain Haddock lives in the luxurious mansion Marlinspike Hall (Le château de Moulinsart in the original French). The hot-tempered Haddock uses a range of colourful insults
Tintin in Tibet trace Chang's steps, and finds a cave where Chang has carved his name on a rock. On leaving the cave, he encounters a snowstorm and glimpses what seems to be a human silhouette. Tharkey believes that Tintin saw the Yeti and convinces him to abandon his friend and return with him to Nepal, since the area is too large to search. Tintin spots a scarf on a cliff face, concludes Chang is nearby, and continues with only the Captain. While attempting to scale a cliff face, Haddock slips and hangs out of reach, imperilling Tintin, who is tied to him.
