Question: Legal Advice on Trademarking a Character

I have an original character which I intend to use for commercial purposes (animation, merchandise, possible licensing, etc). My understanding is that trademarking, as opposed to copyrighting is the more sensible alternative for protection. I would appreciate an explanation of everything that I would need to do to complete this transaction (including any additional characters to this “fictitious world” and any modifications which could take place after establishment of said character(s)? Thank you.

Answer: Based on the minimal cost of copyright registration, it would be prudent to both copyright and trademark the character.
