They don't need one? Series has operated fine without the characters needing a special name for them. On boorus and sites like rule34 all you need is sonic_(series) and optionally original_character. Make an OC? Just say Sonic OC. Also Mobius doesn't exist and the series was always on Earth so the name doesn't work because they would be earthlings and share the planet with humans (who would also be mobians if mobius existed). The only time saying the word would make sense is if you're specifically referring to the original Archie and old cartoon characters and not any of the real game characters
