Do you think "Xavier" is a good bad boy name, and can you help be with a surname for it?

I am writing a book, and I need a name for a bad boy/ ladies man type. I was thinking Xavier. Do you like it? And can you give me a last name to go with it. NOTHING BORING LIKE SMITH, BROWN, OR JOHNSON! and nothing crazy, either. Just a good last name. All ideas for surnames, and first names are welcome!
