Well... technically, yes, but we do have regulations concerning them. For example, you can't just take a character from a different franchise and throw them into the Sonic universe as they are.

Typically what people do is make a Mobian character that's based upon a character from a different franchise, and effort should be taken to not make them exactly like the character from the different franchise with the only difference being species.
