Finn hesitated for a brief moment, before he knocked on the familiar door. Marceline answered quickly. "Hey." he said.

"Hey." she replied. "Where's Jake?"

"Oh, well Lady was pregnant, and she just gave birth, so Jake moved in with her." he said, slightly saddened.

"Hey, it shouldn't last long. Rainicorns grow really fast."

Finn looked up, a small smile barely suppressed. "Really? Well… let's hear some more of the story?"

Marceline nodded. "Alright. I basically lived the way I had with Simon, alone, for a few years. By then, supernatural stuff started to appear."

"Supernatural stuff?" Finn asked.

Marceline laughed, "Back then, candy people and knife storms didn't exist."

Finn blushed in embarrassment.

Marceline threw her pack to the side as she entered an abandoned burger joint. Walking to the back, she started a small fire, and fried some french fries, and a small burger, the last one. The burger for nutrients, and the fries to fill her up. The fries finished quickly, so she put them on a table near the front of the store, and focused on her burger.

She cooked and ate the burger, and took some ketchup to flavor her fries. Upon entering the front, she noticed a dark figure hunched over her food. Throwing the ketchup bottle, she nailed the figure in the back. Turning, his face full of her precious fries, she saw the face of her dad.

"What the GLOB DAD?!" she yelled. He finally shows up after 10 years, and the first thing is to eat her fries? "You don't even need human food Dad!"

"Hey Marceline, I just came to see how you were doing! You seem fine… I'll come by sometime, we can talk!" he replied, ignoring her in favor of leaving, disappearing with the same warning that he had arrived with, none.

Marceline let a few frustrated tears escape. He didn't even stay to let her ask him anything.

She grabbed her pack, deciding then to travel around until she found somebody. Anybody.

It was a little over a year later that she finally met with recent signs of life. A small scavenged town, with noticeably cleared rubble. Excited, she searched the town. Apartment buildings, super stores, even small shops. Nobody. She heard a crunch, and turned quickly, just catching the sight of someone in black. A hit to her head, and she stumbled. She raised her fists and turned quickly. Nausea hit her, and then it was a large rock. She collapsed.

Marceline stirred, feeling cold concrete walls, and a hardwood floor. Looking blearily through bloody eyes, she saw a cleared out room, and someone opened the door. Looking up, she rubbed the blood from her face and spotted the man. He was tall, with pale skin and sharp teeth. He had medium length black hair, and a dark suit of black and red.

"Who are you?" she asked.

"The better question would be, 'Where am I?' or maybe, 'What are you?' or even, 'Why am I here?'"

Marceline crossed her arms, "Then why don't you answer all of those, including, Where is my stuff?"

The man moved to the side. "All will be explained."

Marceline got to her feet, and slipped her hands in her pockets. Following the stranger out, she surveyed her surroundings. It looked like a church, and appeared to have been sealed off. Presumably, there would be only one exit. They arrived in the main hall, a large throne having been erected where the preacher would have been.

A dark clothed figure was draped, almost casually ornate seat. He stood, and Marceline could only just see the movement. An impressive feat, as her demonic senses were higher than an average human's.

"Well, it looks like our guest is finally awake." he cooed.

Marceline groaned. "Does everybody have to be dramatic? This isn't a movie."

The man frowned, taken aback slightly by her lack of worry. "Don't you understand? We kidnapped you, and have you hostage." he said, frustration evident.

"So? That just means if you want anything then you have to feed me, and take care of me. As far as I'm concerned, it would have been worse if you had just left me out in the open." Marceline pointed out.

He looked around at the other people in the room, obvious frustration and confusion pouring from him. "Alright, well why don't you ask WHY we kidnapped you?"

"Don't care. Isn't important. Feed me."

"UGH. We're vampires! We took you to turn you into one of us, and use you to take over the rest of humanity."

Marceline laughed. "What humanity? I've been searching all over, anything left isn't human any longer."

The vampire felt it was necessary to point out, "Well… you are."

Marceline laughed harder. "If I'm human, then so are you guys."

The man grew angry, and decided it would be better if he didn't have to listen to her. Swiftly appearing before her, he tried to bite her neck. Surprisingly for him, she punched him in the face as soon as he leaned in, knocking him back, and onto his throne.

He recovered quickly, and ordered his vampiric followers to pin her down. Marceline was soon overcome by the multitude of vampires, but managed to injure a good portion of the group. When she was finally restrained, she felt her neck be pierced, and all became black.

"Whoa Marcy, you managed to hurt that many! Even without your vampire powers!" Finn exclaimed.

Marceline blushed, embarrassed. "It wasn't much. Now hush, I've got more to tell."

When the newly created vampire awoke, it was to find herself heavily restrained. Multiple chains, apparently of silver, held her down. Marceline laughed as she snapped the weak metal. It can't hold her.

Two vampires, with cheap clothes and cigarettes, were guarding the room. One turned to the other and started chatting. "Hey man, this chick is crazy, right? She beat us down pretty well, and she hadn't even turned yet. Why do you think the boss would make her stronger?"

The other one groaned, "We talked about this man, the people that get turned have to listen to the one who turned them. You don't know this cause you got recruited, and your creator died."

The first goon nodded, "You say that man, but weren't we mostly normal humans before we got turned. This chick is obviously something weird."

"You're worrying to-" The door blasted off of its hinges, crushing him to dust. Demonic green eyes shined through some smoke.

"Dude. I thought we had red eyes…" he muttered, his last words.

Silver chains stabbed through his body, and he burned to ash.

Marceline slipped a large hat over her head as she slowly walked down the beaten road. Behind her, a small church was burning, and a few screams could be heard. Marceline smiled as she shrugged her pack onto one shoulder, despite previously having slight trouble with the monumental amount of supplies that she carried.

"Aw, Marceline. Why didn't you tell me what happened to the vampire jerks!"

"It's for dramatic effect, you can just imagine all the terrible things I did." she hissed dramatically, her face contorting into a demonic visage that promised pain and death.

"Pfft, whatever Marcy." Finn said, undeterred, "just keep going!"

Well, after I got turned, I found out that my demonic blood had activated or something, and all my demon powers mixed with my new vampire powers. I went from being a little freaky, to full on super powered. While the vampires that I fought could fly, turn invisible, had super strength and speed, and a healing factor, I also had demonic transformations, and my powers were much more powerful. They could fly for a while, but as you know, I can fly or float for however long I want.

A great thing, was that I had less weaknesses than these vampires. They had weaknesses to silver, fire, sunlight, garlic, water, and a couple other things, but I had nearly none of these. My demonic blood had strengths to those, and they mostly cancelled each other out. I still had a smaller weakness to sunlight, and my demon blood gave me the weakness to stakes. There was other stuff, but you should know about it.

Marceline floated through the air, the beautiful stars shining on her. She smiled wistfully, but it easily turned into a frown when the great crater became visible. She decided to find a place, where she wouldn't be able to see it any more. The problem with that, was that the mutated freaks had spread, and were currently located in the are that she was planning. Before she could go, she'd need a weapon.

It looks like she'd have to visit dear old dad.

Marceline took a deep breath, her hands clenched. "Maloso vobiscum et cum spiritum." she ground out.

The strange face glowed, and quickly transformed into a portal to the demonic Nightosphere.

Marceline grabbed her pack of supplies and jumped through, portal sealing itself behind her.

Marceline floated high in the air, avoiding the massive pools of fire and blood as she traveled to the home of her father. It didn't take long, and she took a firm face before knocking on the door. To her slight embarrassment, she put a large dent on the door, and fractured some of the wood it was created from. A great darkness shrouded her vision, and she muttered, "Ugh, it's just me dad."

The void disappeared instantly, replaced by the demonic face that could only be her father. "Ah! Marceline. Did you come to take over as the Lord of Evil?"

"No, dad. I need the family axe." she stated, determined to get out of the demonic hellscape as soon as possible.

"Oh? Whatever for? You aren't going to conquer the world for me, are you? That would be a lovely Father's day gift!"

"Ugh, dad. I just need a weapon to kill stuff with, so they don't kill me first." she was incredibly annoyed now.

"Well, come on in. I'll just get it out. Do you want something to drink? Or eat?"

"I… do you have an apple?" she asked, worried about her father's opinion. She had worn her hair longer, and had recently covered her bite mark with her hair, so she wouldn't be noticed if she met someone.

"Sure hon." he said, walking out of the room.

A few minutes later, he was back with the apple and the red dual-sided family axe. Marceline accepted them both, and her father sat down across from her, watching her.

With a sigh of disappointment that he wasn't going to leave, she set the axe down and moved the apple to her mouth, pausing for a brief second, and then sucking the red out of the fruit.

Her father's jaw dropped. "Marceline? What happened honey?" he asked.

She set the apple down, "I met a coven of vampires. I fought them, but the leader bit me. I killed them all." she explained simply, waiting for his disgust or hatred.

"That's daddy's little girl! You killed them all yourself? I'm so proud of you, no wonder you wanted the axe." he beamed.

Marceline found herself nodding along with the conversation numbly, shocked at the lack of reaction from her change. She ended up back in the regular world a few minutes later, done with the visit. I guess he really does care… maybe? She thought to herself. Whatever, I'll worry about this later, for now, it's time to travel.

It was this journey that she finally encountered some of the remnants of humans.

Thanks for reading. I have some big plans for this story, and for a few minor crossovers. Anything in a weird level of technology, and humans that seem to be mutated somehow. Any idea what it is? Next chapter will have a timeskip of about 30 years, give or take. I'm trying to keep the timeline and ages pretty loose. Review so I know if you like it! It motivates me.
