What is Sonic's real name?

Could you please clarify for me, what exactly is being referred to by "Sonic"? Is it a character from a popular video game series, a musician, or something else entirely? Without that context, it's difficult to give a definitive answer to the question "What is Sonic's real name?" If we're talking about the blue hedgehog from the Sonic the Hedgehog video game franchise, for instance, it's worth noting that in the original Japanese version, he is known as Sonic the Hedgehog, and his real name, if he has one, is not commonly disclosed within the games or related media. However, if you're referring to a different Sonic, I'd be happy to provide a more specific answer if you could provide a bit more context.
