Well it is already a name for a hedgehog created by a gaming company but if you want to call your hedgehog something don't choose sonic because it doesn't actually suit hedgehogs, it is sarcastic because they are very slow and yours could never be as fast as THE Sonic the Hedgehog. It would be an insult to your poor hedgehog.
Another opinion:
Sonic would be a cute name for a hedgehog.
Sonic the hedgehog is, as his name suggests, a hedgehog.
Olgilvie Maurice Hedgehog, but he hates that name so he nicked named himself "Sonic" the Hedgehog because its cool, and he is fast!
Queen Aleen/Bernadeth the Hedgehog (she prefers Bernie) There is two mothers for Sonic in different parts... There's Queen Aleena in Sonic Underground and there's Bernadette Hedgehog in the Sonic comics His Mothers Name is Queen Aleena Hedgehog.
I came up with 2 possibilities:1. In one episode of "The Adventures of Sonic the Hedgehog," Sonic says: "That's Hedgehog. Sonic the Hedgehog." Although this is just supposed to be making fun of the James bond series, it could actually be...2. In "The Adventures of Sonic the Hedgehog," Sonic calls Tails his "little bro." Since all brothers have the same last name, and Tails' last name is "Prower," that could also be Sonic's last name.Okay, Sonic's last name is actually Hedgehog.
