It's possible that you can suggest a character to Galaxy Zento and have them become part of my universe. If you do, you have to pay attention to the legalese!
Any submission of character made to Galaxy Zento or its creator, David Wilde become the sole property of Galaxy Zento/David Wilde.
Any submissions will be thoroughly checked for originality to make sure that they infringe on no other copyrights.
Acceptance of a character is no guarantee that any publishings will be made on said character.
If you do this, you agree that you are doing it solely for the thrill of seeing your character come to life, if accepted or possible.
Naturally, any resemblance of any Galaxy Zento character to any other person real or fictional is purely coincidence and likely a figment of your imagination.
