[@Hexaflexagon] I have a few ideas for a character storming in my mind at the moment! I do please pardon me for this question. Am I allowed to have a known but unknown character? 
I was thinking about a well known - kind of ish character that is a bounty hunter. Around ten years ago just kind of showed up. No one really knows what is under their suit of armor - a true appearance that is hidden that could be possibly shown later in the actual rp?
Also this character no one knows their gender at the moment - true identity - species, etc.
