Hey guys! I decided to write my first Adventure Time fanfic! :D It's my favorite cartoon (next to My Little Pony: Friendship is Magic, but I have absolutely no idea how to write a story pertaining to that show…) and I've always wanted to write a fic involving Marceline, I just never really had an idea for one until now! Okay, here it is. C:

Disclaimer: Unfortunately, I do not own Adventure Time nor do I own its characters.

"ARGH! Where the lump are you!" Marceline yelled, dashing into the dark alley, looking around, her eyes glowing red. There was a crash. "Hisssss!" the vampire queen glared as she turned around to catch the creature she'd been searching for, but only discovering that a garbage can had been tipped over on its side. There was no one else in sight. "I know you're here," Marceline inquired, looking around, sniffing, "I can smell that you're near… show yourself!" she cried out, kicking the trash can in frustration. Silence. No response. Then the air grew still, and the vampire hovered down, placing her feet on the ground. Whatever it was she was looking for, it was getting closer. Its scent overwhelmed her, getting stronger. She couldn't quite seem to make out what it was…

…that's when she heard the whisper,

"Boo."

Marceline wasn't a fearful type of girl, standing her ground. Though, she hesitated a moment, before clenching her fist and turning around, swinging a punch, and missing. She swung her arm back once more in an attempt to try again, but her momentum vanished as soon as she saw the creature in front of her. Her arm dropped, slowly, and she froze in place. She locked eyes with him, afraid that, if she were to blink or look away, that he'd disappear from sight.

"Who are you?" Marceline asked, her voice soft, just above a whisper.

The creature gave her a smile, "Marshall Lee," he said, floating closer to her, getting into her personal space to whisper into the girl's ear, "The Vampire King."

Aaaand, that was the prologue! If I get any good feedback, I'll continue on and post the first chapter, which will explain why Marceline was angry in the beginning and such. Yeah. I hope you guys like it!
