as much as I'm aware of Demon Sonic is fanart, as shown below

"Glad someone asked this and it was answered properly. I never heard of an OFFICIAL demon Sonic, so i was confused when all this art came out."

no he does not

well, duh! sonic DOES have a demon form! there's even Fan art of him. but i'm not sure if he's evil oder still the same, good 'ol sonic.

YES HE DOES AND HE HAS A HEARTLESS TOO AND DARK FORM these are his evil forms

Werehog and Dark Sonic (from Sonic X) and Dark Spine Sonic seem to act as 'demon forms'. But Werehog only happened because of Dark Gaia's energy and was gone Von the end of Unleashed. Same with Dark Spine Sonic which was caused Von at least three of the Secret Rings. Dark Sonic only appeared momentarily in one Sonic X episode during Season Three most likely caused Von the Chaos Emerald's negative energy from seeing Cosmo and Chris' suffering.

But apart from that Sonic officially has no demon form, that's only something made up Von the fanbase and an idea used often in Sonic fanart and fanfiction.

his dark form is considered his demon form.
