Me? He has the power to bake a very good victoria spongecake.
My avatar? Well he has the power to control inferior vampires (since he's King and a Pureblood there's very few the same level as he is so all vampires basically), he can control a bucket load of things (Wind, the ground beneath him that sort of thing), he can turn other people into vampires...Oh and he's sexy.
Yup one of Kaname's vampire abilities is the power of sexy since in Vampire Knight all vampires are beautiful, it says so itself. XD
