Skyler and the Vampire Princess by OmegusXIII reviews
(AU) Marceline had lived a thousand years old, certainly long enough to become a Vampire Princess. Hoping to make her own mark on Ooo, she left the Vampire Kingdom, a society created from the Mushroom War's wake, and tried to find someone to jam with. At first, she thought she was destined to jam alone. But one human girl changed that: Skyler Campbell. (WARNING: WILL CONTAIN LEMON)

Finn Campbell by GentleNight reviews

The Exicutioner by Sweetenlow reviews
Finn isn't the hero we remember nor the adventurer we adore. He isn't loved by the people he serves nor revered by anyone as a role model. No child who sees him wishes to be him. No adult who watches him ever envies him. He is the shunned one, the doomed man, the performer of Justice. He is the Executioner. The one who kills in the name of Justice. And lives for nothing more.
