Merlock the Magician is the main antagonist in Disney's 1990 animated film DuckTales the Movie: Treasure of the Lost Lamp. He is an evil sorcerer who supposedly tries to gain unlimited wishes from the magic lamp combined with his talisman. He also appears as the main antagonist in the videogame Donald Duck: Goin' Quackers.
Merlock is an anthropomorphic wolf sorcerer who possesses a magic green talisman that gives him the ability to transform into animals, including a hawk, a vulture, a rat, a cockroach, a griffin, a bear, and a cougar. When placed on the Genie's magic Lamp, the talisman grants Merlock an unlimited number of wishes to be granted, instead of the usual three for everybody else. When he first possessed the lamp, some of the sorcerer's wishes that were unwillingly granted by Gene the Genie including his own eternal life, the sinking of Atlantis into the sea, the destructive eruption of Mount Vesuvius due to Merlock's hatred of Pompeii and its creation of anchovy pizza. It's also assumed that Merlock wished that his talisman couldn't be given to others if they ever got their hands on the lamp.
In the film, Merlock is obsessed with retrieving the Genie's lamp, which he apparently lost to the thief Collie Baba several millennia before. Collie Baba buried the lamp, along with a large amount of treasure, in a pyramid in the middle of a desert. When Scrooge McDuck and his family Huey, Dewey and Louie Duck and Webby Vanderquack, accompanied by their trusted friend and pilot Launchpad McQuack, came searching for that very treasure, Merlock with the the aid of his henchman, an Arabic explorer named Dijon, attempts to use Scrooge's ambition to obtain the lamp for himself.
In the end of the film, Merlock finally combined his talisman with the Genie's Lamp once more and wishes to transform Scrooge's Money Bin into his gloomy flying castle. Scrooge and his four niblings confront the evil sorcerer who merely wishes Scrooge to be blown overboard. The children manage to get the lamp and toss it towards Scrooge, so that he can wish to save his life.
Merlock turns himself into a griffin and recovers the lamp from Scrooge, after defeat, who grabs him and smacks him repeatedly with his cane, making him lose the talisman and apparently fall to the ground. At the end of the film, when Genie was freed, Dijon turned back into his original form. This indicates that all of the other wishes previously granted by Genie, including Merlock's wish for immortality, were also undone.
