Neil Gaiman is owed royalties from characters in Todd McFarlane’s Spawn comic-book series, according to a ruling by a federal judge in Wisconsin, reports Variety. The judge ruled that characters Dark Ages Spawn, Domina, and Tiffany were created by Gaiman when he worked on an issue of the Spawn comic in 1992, at the request of McFarlane. The dispute between Gaiman and McFarlane has been brewing for years, since a 2002 jury originally found that Gaiman had a copyright interest in three characters he’d worked on for the property.
