Who are you? (Marceline x Reader)

You are a human, one of the ones left in the land of ooo, only your not really an actual human, your a clone from Finn's DNA mixed with others like the candy people and flame people, and princess bubblegum is the one that created you, unknown to anyone else, of course up until now. Princess bubblegum finally lets you wandered the candy kindom but only that, not the rest of ooo. Marceline the vampire queen now visits the princess a lot more often now along with Finn after everyone finally meets you and you all get to know each other since the princess is persuaded to be less strict but by who? All of this leads to ask the question just who are you really? The cover and story line are the only things that belong to me. Adveture time belongs to its creator and you obviously belong to you. You can be a female or a male reader but for now I'm going to write from the POV of a female reader, have fun reading.
