User blog comment:David Bear/Sonic's home world is in fact Mobius, not Earth/@comment-477304-20130419215734/@comment-3359241-20130419230521

Well Mobius is only in the comics and I hate the in game humans in Sonic games so I figured why not just have Sonic's home planet be Mobius where there are no humans except Eggman, Master Mario and all of Mario's friends.
