You're not in kitsune form, though.  No natural bite attack for you :P<br/><br/>I'm willing to say you can bite him as an unarmed attack (1d3 damage normally), but I'm not sure about being able to sneak attack with it, or if you avoid the -4 non-proficiency penalty.  And if he's flat-footed depends on if he hears Damian (again, haven't fully statted out these guys yet).<br/><br/>Edit: Whoops, just noticed you just transformed.  Give me a sec...<br/><br/>Edit 2: Ok.  Transforming into a ktisune again is a standard action (assuming you don't have the feat; I don't see it on your character sheet).  I'll give you a surprise round to transform before going to normal initiative, but you won't be able to attack as well (unless you win initiative, of course).  From here it's a normal combat, and yes, the bite would be a surprise attack if Mardon hasn't acted yet, as he'd still be flat-footed.<br/><br/>Feel free to yell at me if any of that isn't right.
