Back during the allied race fever thought it might be cool to have wild clans for each race. Like Au Ra getting the demonic looking concept art, miqote getting fuzzy mithra treatment, lalafell getting those small moogle-kin look or vivi (mammet/yuke like), Viera might get like lions rabbit, etc. Hroth wild clans could just be a more direct translation of FFX lol.

The Au Ra concept art was always really cool..
