The Igors are a recurring set of characters in Terry Pratchett's Discworld series of novels. They are members of a clan of servants from the region of Überwald, all of which are named Igor. The Igors are based partially upon Mary Shelley's Frankenstein's Monster, and partially upon the hunchbacked assistants in Universal and Hammer's film versions. While they are born in the normal fashion, the clan's strong tradition of surgery usually means that by the time they would have grown to maturity in the natural way many of their body-parts have already been swapped around repeatedly, mostly within the clan.
