Chainaxes! Jesus Christ does Edward Cullen need one of those to the face. I don't care if he's immortal, having your face torn up into little tiny pieces by a madman in crimson armour laughing with the sheer joy of reducing your skull into red mist redefines immortality as never ending pain for the sparkly vampire knockoff who wouldn't dare cross standard vampires because they'd tear him into almost as many pieces for making them look pathetic.
How about a Sunburst? Would the concentrated ball of light and fire turn him into a sparkly cloud of ash? Would each piece shine like a brilliant diamond, creating a fog that could blind anybody within five hundred miles? To be honest, I don't care either way. Short of brutal mutilation at the hands of a Berserker of Khorne and his trusty chainaxe there is no better way to deal with this creature. After all, it is the ultimate weapon against the forces of darkness - who would probably steer clear of possessing the bastard out of fear that he would make even Inglets look formidable.
