Same here. c: I think he's my favorite of the new characters just from his design alone so far. XD It might be because he's a reptile, you don't see many of those in Sonic. Pretty much mammals for the most part. :I
They're the only ones I know of, too. The Archie comics may have some others, but I never cared too much for the comics, personally. So I can't confirm if there are any. It'll be nice to have a new reptile in the games. More variety in species.
