What happens when Harry Potter gets turned into a very protective Royal Living Vampire?

Diablous Sirius Riddle, or Harry James Potter, heir to Hogwarts, his life just got a LOT bit weirder. With Aunt Petunia and Dudley as the good guys, Dia's life couldn't be any better, until he gets to school...... UNDER MAJOR RECONSTRUCTION/EDITING. MAJOR PROPS TO MY EDITOR/READER FOR PUTTING UP WITH ME.

So, Harry and Voldemort are circling each other, and then Voldemort kills Harry. What happens? This is an alternative ending to the book. I don't own Harry Potter.
