Scooby-Doo (DC Comics)
His brother Edward created the illusion of the Phantom Hound, a legendary curse in his family that meant the family line was coming to an end, by coating an ordinary dog with luminous paint. The household was running out of money because nobody had discovered the treasure map that the former Lord Darkmoor wrote on the back of the will. Edward thought the Hound would frighten his brother into selling. When the gang helped discover the treasure, Edward confessed and all was forgiven.
