:In any case, just because Red Smoke may be a human being doesn't mean that we all of a sudden don't need sources in order to have a good article about him. You can't act as the exclusive source about yourself no matter who you are, and most people won't count as sources either. It's only people who're known to be reliable sources of information that can count as sources.
