A couple of things: The way a DMCA works is that the copyright holder contacts Fandom, and we take the content down. Then a counter notification can be sent to us, and (if it's all correct) we would put the content back up. Then it would be a matter between the copyright holder and the potential infringer - which would likely be sorted out in court.

Also, you don't have to register copyright. You automatically hold the copyright to something you created, no action required. All that matters is that it's your own work.
