Xavier is cold, cunning, calculating, intelligent, intimidating, touchy, rude, strict, bossy, and dismissive to most if not all people. He's military harden and doesn't mind nor care for killing, but he prefers to torture or interrogate information out of people instead of straight out killing them. He's also very cut throat. Those he finds 'worthy' enough, mostly prisoners of war he finds weak or cute enough, he'll keep around with him as a sort of pet or trophy. Often seen with a rose in hand.
