Rascar Capac is the mummy in The Seven Crystal Balls. He is an ancient Incan priest dug up by the Sanders-Hardiman Expedition. Professor Hercules Tarragon displays the mummy in his house. When lightning strikes into the chimney, it sends a fireball hurling through the living room, and the fireball crashes into Capac, apparently vaporizing him. That night, Tintin, Captain Haddock, and Professor Calculus all have the same dream where Capac climbs into the room carrying a crystal ball and smashes it onto the floor. What happens to the apparently resurrected mummy afterward is unclear.
