Marshall Lee

Marshall Lee (full title Marshall Lee the Vampire King), is the gender-swapped version of Marceline, created by the original series designer, Natasha Allegri and featured in "Adventure Time with Fionna & Cake." He is feared by Cake like Marceline was feared by Jake. He makes a small appearance in "Adventure Time with Fionna and Cake" and does not have a speaking role, though Natasha Allegri really wanted him to. He didn't talk because of the time limit.

Appearance
Marshall Lee has pointy ears and light blue skin. An alternate character sheet depicts him with green skin, but it was only used in one scene with a special lighting.

His hair is shorter than Marceline's but he has a matching permanent bite mark. He initially wore a grey plaid shirt, but now wears a red and black plaid shirt. He also wears dark blue jeans, and brownish-white sneakers and looks sexy without a shirt.
