Given that he is a giant blue anthropomorphic hedgehog and the only character in the sonic mythos capable of running faster than the speed of sound unaided I think it is safe to assume he was a little different...
No they are both different hedgehogs.
sonic is just a hedgehog not special.
Sonic the Hedgehogs shoes are made out of the powerful sneakers.
no he's a different species sonic has siblings but there both hedgehogs
Ever since the original series from Adventures of Sonic the hedgehog, to Saturday Morning Sonic, to Sonic underground, to Sonic X, to current video games, there are many hedgehogs. The main hedgehogs are: Sonic, Manic, Sonia, Shadow, Silver, and Amy. there are others but carry a minor part in the Sonic series.
Silver the Hedgehog, Shadow the Hedgehog and Amy Rose the Hedgehog.
His accent is Japanese in Sonic X and American in sonic games
it is sonic 4 ep 1
sonic underground
I think theres that purple one and Tails.
Other than the two both being hedgehogs, they have no family relations.But shadow was created using sonic's DNA
Because hedgehogs are awesome.
