Royal Margarine Cookie is tall, with dark skin and blond hair. He has a scar above his left eye. He has a wyvern animal companion, a female cream-colored wyvern named Buttercream. He is charming, flirtatious, self-centered, and overly confident. He's a smooth talker but struggles to be vulnerable and genuine at times. He tends to laugh things off and seek glory, and dislikes menial tasks or manual labor. He lies about Buttercream being a dragon, attempting to hide the fact that she is a wyvern.
