Needs new gamertag

Im getting a new gamertag because the one I have now is getting old. I cant think of anything:-/ I tried gh0st and ghost but they are both taken. I can use gh0st with numbers but I want something basic (no numbers) and more original. Something that sounds cool or something that is funny that I like and will like being called in games for years to come. I kind of want gh0st so maybe Ill use that with another word in there but what?

Can you guys help me out with your best gamertags you can come up with for me that I can use?
