DUDE! Been totally aching to play a Riddick charrie!
Well, he's an ex-ranger.
So I'd probably use this, lose falling star for either stone dragon or iron heart, as per the acf.
Full bab, ranger skills, good for/ref (gotta find a way to boost will...), favored enemies, plus shadow hand, tiger claw, and one of the aforementioned disciplines. You're set. Oh, plus bonus feats. Woot! Maybe mix in some barbarian, for uncanny dodge, same skills, rage...
Plus some race with darkvision. (I'd rather a human with the Dark Template; thematically fits, as he inherits it from his Furyan race, and is a fast runner/good sneak. I'd probably go Blooded template too, since his cry and boosts work well)
Now, you've got a full BAB martial monster, with the background appropriate to the base charrie and the eyes. You have, my good friend,
Richard B. Riddick.
