A/N: Warning! Character death! (Don't worry, no one you'll miss...probably)
Marceline burst through the wall of Bubblegum's laboratory, the Lich in her grasp. With a wild cry, she slammed him to the ground not letting up for one second as she clawed at him, actually leaving marks in his skeletal frame. With every attack, images kept flashing through her mind-Finn lying lifeless on the floor, the waxy color of his skin, his limp body in her arms as she tried in vain to bring him back to life. She had been too late, she knew that now.
Finn was dead. The boy she had raised and come to love was gone. And it was all that monster's doing. Marceline let out a scream that was part human and part animal as she continued attacking the Lich mercilessly. She wanted him to pay. She wanted him to hurt as much as he had hurt her. As much as Finn must have hurt when he was stabbed.
Finally, Marceline stopped. She stood up, panting heavily as she looked down at the Lich. He wasn't moving. Marceline let out a sigh.
Suddenly, the Lich's eyes started glowing again.
"Was that supposed to hurt?" Before Marceline could move, the Lich shot her with a powerful energy blast. She fell to the ground, trying to keep herself from falling unconscious.
"That's right." The Lich said with a smirk. "Bow to your new ruler."
"Go. To. Hell." Not the smartest thing to say. The Lich started stomping on Marceline again and again, until she finally turned back into her more humanoid form. She lay gasping for air in the Lich's huge footprint, every part of her body in pain. Before she could even think to pull herself up, however, the Lich snatched her up, and started squeezing her in his hand, determined to snap her like a twig.
Suddenly, a yellow fist stretched out and punched the Lich in the face. The villain turned his head slightly to glare at Jake.
"Jake…" Marceline gasped. She wanted him to run. Trying to fight the Lich would be stupid. He was far too strong now. He had her, the Vampire Queen, on the brink. She didn't want anyone protecting her, especially if that meant they were going to die doing it. Thankfully, before the Lich could obliterate Jake, Hunson Abadeer's voice called out
"MARCELINE!" The demon lord glared at the Lich.
"That's my daughter! Put her down now!" The Lich just laughed.
"I gave her a choice to join us; she turned me down and attacked me. I had to defend myself."
"By killing her?!" Hunson growled. "I'm an evil, soul-sucking monster, but I draw the line at anyone hurting my daughter!"
"Well then, I have no further use for you."
"No, wait, I…!" Hunson didn't get a chance to finish. The Lich engulfed him in green flames, and Hunson screamed in pain as he was burned into ash.
"Dad…!" Marceline said in a small voice.
"Now then," The Lich turned back to Marceline, "To finish you off once and for all."
Without the Lich's help, Marceline actually stopped breathing. This was really it. She was really going to die.
A blur suddenly whizzed at the Lich's head.
"What?!" The thing didn't let up. It just kept zipping around the Lich, attacking and genuinely hurting him until he finally dropped Marceline with a roar of frustration and pain. The vampire girl fell towards the ground, the wind whistling through her long black hair. Before she reached the ground, the same blur swooped down and caught her in its arms. The being flew her away a safe distance from the Lich and took care to land gently.
"Marceline? Are you alright?" Marceline's breath caught in her throat. It couldn't be. It just couldn't be.
But it was. Finn stared down at her, a concerned look on his face. He looked pretty much the same, except for his skin, which now had a slight green-gray tinge to it, and fangs. Marceline felt her heart swelling a little more the longer she looked at him. She had managed to successfully turn Finn after all!
"Finn...you're alive." Tears of relief and happiness started to fill Marceline's eyes.
The touching moment was ruined, however, by the Lich's roar in the distance. Finn glared out at the monster.
"This isn't over yet." He placed Marceline down gently onto the grass and turned to the Lich.
"Marceline, you've protected me for most of my life." His tone was completely serious, and Marceline immediately knew that that little boy she had saved all those years ago was gone.
"Now it's my turn to protect you."
A/N: Well, it's what you guys have been waiting for. Finn's finally a vampire, and he's going to kick some Lich butt! Sorry this chapter is so short-I actually WAS going to make it longer, but I worked on it late at night. I should start practicing to make my chapters longer, though. I promise, the next one will DEFINITELY be longer. And yeah, I imagine Vampire! Finn as being more or less the same color as Marshall Lee. And yeah, I know the AT version of hell is the Night-o-Sphere, I just tossed that line in there for drama. Hey, one question before I leave, though, and I know I'm going to sound like a total noob for even asking this, but how do you name the first chapter of a new fanfic when you post on here? I forgot how :*(
Anyway, stay tuned, and keep reviewing! Reviews keep me going!
