User blog comment:David Bear/Sonic's home world is in fact Mobius, not Earth/@comment-3027069-20130420153349

I'm not really sure where Sonic is from, as many sources seem to contradict each other. All I can say on this is that if Sonic is from another world/dimension and came to Earth, Earth seems to be as much of a home to him as anywhere else.

Darn multiple continualities. Always making our heads spin.
