My favorite OC for like a year and a half now is my character Princess Primrose Pennant of Prendaloth. She's a character from a comic/story that's a work in progress.
She's a princess from an isolated northern kingdom known for their warriors and skills on the battle field, who falls in love with a prince from a beautiful kingdom by the sea. She's has a stoic demeanor, but she can play the part of a "normal" princess very well. She is intelligent, loyal, and mostly stubborn. When there's a goal set in her mind there is nothing that is going to stop her from achieving it. She would prefer to be bound to the hip to her prince, but sometimes people have other plans that involve kidnapping.
