When he was three, Xero's parents were captured and put in a maximum security prison, as space pirates often are, and he was left orphaned to his paternal grandparents, who had thought there son and daughter-in-law were really couriers!
Xero was not a good student, he much too liked drawing pictures of intergalactic battle and space pirate duels. Flunking out of normal school and not knowing that most people normally went to pilot school first, he took his flight test. His instructor is still in a coma, and as a result, the pilot license facility passed him, even though he'd managed to break an indestructible student pilot vehicle.
He can now be found annoying large sums of people over general communication or... annoying large sums of people over general communication, he doesn't really do much else.
