Marshall Lee

Marshal Lee is the gender-swapped version of Marceline, created by the original series designer, Natasha Allegri. Like Marceline, he is a vampire, As seen in this picture, Cake is every bit of afraid of Marshal Lee as Jake was afraid of Marceline. He may be a Vampire King, since Marceline is the Vampire Queen. Due to this, it is possible he could have been prior to the series of Adventure Time, due to Pen Ward's statement of Marceline killing the previous Vampire King to become Vampire Queen, or he could be an entirely different Vampire King if any.

Appearance
Marshal Lee has longish hair, blue/gray skin, fangs, and the same bite marks like Marceline's. He wears a gray plaid button-up, long-sleeved shirt with red buttons and two pockets, jeans rolled up to his ankles, and red, white, pink and gray high-tops.
