The Official Sonic the Hedgehog Yearbooks are not directly related to Sonic the Comic, beginning printing before the original 1993 publication of the fortnightly comic and owned by a different company, Grandreams Ltd. However, they are notabale for including the earliest Sonic the Hedgehog-themed comic work made available in the U.K., and including a detailed account of the "Kintobor origin" of Doctor Robotnik (also used in the STC backstory) as a text story. They also feature seminal contributions (albeit uncredited) from key STC artists Richard Elson and Jon Haward, and the scriptwriter Alan McKenzie.
