Mine has a spaceship. Details to come later when I've fully designed it, but you can imagine it as the futuristic equivalent of the Mi-24 Hind. Basically it's a big-ass multipurpose gunship and troop transport but which also has living quarters for when he's away for long periods.
It functions as his main place of residence when he's not planetside, or when he's travelling. So it's quite an important a part of his character, because it's where he pretty much lives and works from. Oh, he works as a bounty hunter/mercenary/bodyguard usually. Big-ass personal gunships are a pretty handy thing to have in that line of work.
