Xavier, where do I even begin... He's a daddy's boy, and is like every typical rich son; he loves his parents because they have money. He "works" at his dad's country club, either playing golf or relaxing in the spa. He is extremely egotistical and snobby.

Xavier should have a very posh British accent in the mid-low range, but you should be able to do a similar voice at a high pitch as well. His voice varies a lot.
