Mobius is the name of a fictional planet that appears in several spin-off media for the Sonic the Hedgehog franchise. Mobius is considered one of the common elements for early Sonic canon, adopted mostly in Western regions, with several Sonic television shows, books, and comics taking place there; the original Sonic games for the Sega Mega Drive, and later the for Sega Game Gear and Sega Master System, were also said to take place on Mobius.
The name "Mobius" was not used by the authors of the games' Japanese manuals; the earliest use of the word was in the later drafts of the Sonic Bible which referred to Mobius as Sonic's home planet. It was later used in the Sonic the Hedgehog promotional comic and the Stay Sonic guidebook.
