Suggestions with a cool username for a Minecraft Username?

So, I wanted to ask some suggestions of usernames for Minecraft, For instance: Voidwalker, Nightmare, Necromancer. Not the words style, but the plain one word name. Something that wouldn't be acceptable is "DrunkDude" and some X's, numbers and some other stupid words to add. Philosophical and some logical names would be good. Even a form of a personal name would be good with an ending of -zkii or other cool endings that you may come up with.

Thanks!

Added (1). Some grammar mistakes in the question, sorry >_>

Added (2). Daniel - No, I didn't want Void in the name, it was an example. As I mentioned, not the words style and expression. Just something you can think of or make up.
