Characters Everyone Can Use

If you want to use one of my characters, please message me first so I can know. I really don't want these taken without asking me because I work hard to make up each and every aspect of these characters. If you are wanting a character but may change a thing or two, that's fine but please let me know and don't completely change a character. Also, I would be happy to follow you and read the story(s) you decide to use my characters in.
