Go on any given character reference sheet on Deviantart and you'll probably find the disclaimer "Character/Fursona (c) ME ME ME ME ME ME DONT STEAL!!!!!11!!1!!
1) Can you even copyright a character to begin with? (I heard you can't, that you can only trademark a character)
2) What process would you go through to claim copyright/trademark of a character?
3) Fact or fiction? Once you put something on the internet (Deviantart, for example) it is automatically copyrighted to you without filing a copyright claim with the US Copyright Office (and paying the 35 dollars to do it.) I've seen many people make this claim.
4) What can you copyright/trademark on a character? Can you copyright/trademark design elements (ex. hair styles, markings, etc) or does it cover the whole thing?
Let me know if my wording is a little confusing, I can try to clarify it more. Feel free to ask your ownquestions about character copyrights or just toss in some vital facts if I missed anything important enough to cover.
I look forward to hearing some answers! Thanks!
