Sonic the Hedgehog’s full name is actually Ogilvie Maurice Hedgehog.
This is a bit of a contentious one, though, as some fans claim that it isn’t canon. This is because Sonic’s full name was never published.
Archie Comics, who publish two different Sonic comics, released a comic that mentions that Sonic’s middle name is Maurice but never mentioned his first name.
One of the Archie Comic writers has since shared that Sonic’s first name is actually Ogilvie.
Fans disagree, as they say, that Archie Comic’s Sonic isn’t true canon, only the video games and the Japanese manga are.
