Who is the voice of Sonic?
Really, it depends on which show and games you're talking about.
Like in the old freedom fighter sonic show, Jeleal White played the
voice of sonic, but, in the new version in anime came out in 2007
on 4Kids tv Jason Griffith played his voice and also shadows. He
also played the voice of both hedgehogs in Sonic Adventure, Sonic
Adventure 2 Battle, Sonic hereos, Shadow the Hedgehog, Sonic
Riders, Sonic the Hedgehog, Sonic Riders 2 Zero Gravity, and so
on...
