Thinking about Inuyasha. He's definitely a Half-Fiend Longtooth Shifter. Dog demon father, human mother is easily fluffed into the shifter abilities since he never turns into a full animal form, but can become more animalistic in appearance at times. Has natural claw attacks, which is something he's shown using quite frequently. Classes I'm thinking he's primarily fighter/ranger. Not sure if there's a good prestige class for him since he's really a heavy front line physical fighter that either attacks with his claws or his Katana, and doesn't have much in the way of magical attacks.
