Goodbye Ash
Finn and Marceline were very good at fighting. Finn was better than Marceline when he needed to be but was usually as good as her. They had defeated July exactly two months ago, and for the first time since then, they were scared. Finn was terrified because Marceline's father was beyond furious at him. Marceline was terrified because her father wasn't being quiet about it. It was partially her fault anyway.
Marceline had moved to the Nightosphere because her father had wanted her too. A few hours ago she had been puking he guts out and had began to wonder why she had been doing that for several days. The first thing she tried was her temperature but it wasn't any higher than it normally was. Then she tried taking Pepto Bismol but it still didn't help any. After a few more failed attempts she had a theory but was praying she was wrong. Unfortunately she was right. A little while later she was sitting in a beautiful field with Finn and was happy. Unfortunately he needed to know.
"Finn," Marceline said.
"Huh?" Finn asked looking over at her.
"There's something you should know," Marceline said. "I...I'm pregnant."
Finn hadn't known what to say but had eventually just said he was happy. Marceline had decided that she was happy about it as well. Then she remembered that in her rush to go to Finn's house, which was her old house, she had left the pregnancy test on the counter next to the sink in her bathroom. Her father had found it and had instantly gone to the field and began screaming at Finn and Marceline.
Now Finn was in his Fury-vampire hybrid form and was standing up to her father. It wasn't very smart but he knew that however bad his punishment was, Marceline's would be worse.
"How dare you tell me what to do!?" Abadeer shouted.
"All I said was that you should calm down before you attract any unwanted attention," Finn said evenly.
"Like what!?" Abadeer shouted.
"Like the Bloodrunners that July created before we could kill him," Finn said evenly.
July had created a new race of creatures that could shape shift between human and a random creature. Their personalities as both the human and the other form always matched the shift form. Finn had hunted and killed hundreds but Bloodrunners could create new ones by biting something, alive, dead, or inanimate, or they could use some spell that made exact replicas of existing ones. Basically they could create a thousand new Bloodrunners in under a day. Finn knew they were planning something because they would have taken over the entire world by now if they weren't.
"I'm deathless," Abadeer said quieter than before.
"So was War," Finn said. "At least before he met the Bloodrunner hoard."
"What happened?" Abadeer asked.
"They tore him apart," Finn said.
Abadeer paled a little and then smirked.
"You're just trying to make me forget that I'm angry at the two of you," Abadeer said.
"No," Finn said pulling something out of his bag.
He unwrapped it and revealed War's severed head. Abadeer paled a lot and disappeared in a puff of smoke. Marceline was also pale but for a different reason. She could see three Bloodrunners standing on the edge of the field.
"I see them," Finn said putting the head away. "Caltrum Hailstorm."
Three Finns jumped out of the trees behind the Bloodrunners and shot ice Shuriken at the Bloodrunners. The Bloodrunners were shredded and the three Ice Clones melted. Marceline liked that he had learned to be an ice ninja. She was jealous but Finn was teaching her and she was getting fairly good at making a cool breeze.
"I'm so jealous at how good you are at that," Marceline said.
"You're learning," Finn said.
"Not as fast as you did," Marceline said.
"I was an ice ninja back when I was thirteen," Finn said.
"Oh," Marceline said.
Finn didn't say anything but he was trying to decide whether or not to propose. Marceline hadn't been around very much lately because she had taken over for her dad in running the Nightosphere. He wasn't certain she would say yes but he did trust that she was still faithful to him. He knew she hadn't even considered cheating or leaving him.
"I want to ask you something," Finn said.
"What?" Marceline asked.
Before he could say anything a portal to the Nightosphere opened and a vampire stepped out. The vampire looked a lot like Marceline but was male.
"Who are you?" Finn asked.
"Marshall Lee," the vampire said.
"He's my brother," Marceline said. "Did Dad free you?"
"Nah," Marshall Lee said. "I'm just sneaking out for a while."
"You mean you're going to spend another night with Fionna," Marceline said.
"Oh hush," Marshall Lee said. "From what I hear I'm not the only one disobeying Dad these days. You look a little over fed."
"I'm sure you know already," Marceline said.
"So you really are pregnant," Marshall Lee said.
"No more pregnant than Fionna," Marceline said.
"How did you know that?" Marshall Lee asked.
"You're an eternal seventeen year old boy," Marceline said. "You're never quiet."
"Does Dad know?" Marshall Lee asked.
"Are you kidding?" Marceline asked. "He sleeps like a rock."
"Who's Fionna?" Finn said.
"The only human female left," Marceline said. "Now the only human left."
Finn sat quietly and watched the clouds until he saw one that looked exactly like the Ghost Rider fighting Blackheart. He smirked and then saw one that looked like a dragon. Then he saw one that looked like a swirl and as he watched it he began to see the future. It was what Marceline had told him in his dream.
Finn was standing on a huge field. There were two different buildings in the distance. One was a tower made out of diamond. The other was a tower made out of ice. Finn knew that Marceline was being held in the Ice Tower and his target was waiting in the other. He had about five minutes before Marceline was assassinated and at the same time his target would turn everyone on Earth into a monster. It was Halloween and everyone would become whatever monster they were dressed like. Everyone would be evil and all would go after Finn. They wouldn't be evil like Abadeer had been but would be evil like the Lich.
"Why is the hard decision never easy?" Finn asked himself.
He wanted more than anything to save Marceline but he had to stop his target. He could try making Ice Clones to stop his target or to save Marceline but something told him that it wouldn't work. He sighed and turned toward the Diamond Tower and created an army of Ice Clones.
"You know the plan," He said. "Level the tower as soon as you get there. Make sure he dies with it."
Then Finn created himself a pair of Ice Wings and flew to the Ice Tower. He kicked the door down and began hacking his way through the Ice Golems with the Axe-guitar Marceline had given him. After a couple minutes it smashed and he began using every ice jutsu he knew. After a couple more minutes he kicked the doors to the top floor off their hinges just in time to see an Ice Golem bring a diamonite axe down and remove Marceline's head. He dropped to his knees and heard a crash. He looked out the window and saw that his Ice Clones had been crushed by the Diamond Tower and his target was beginning the spell. He flew out the window to stop his target but suddenly a Golem jumped off the top of the Ice Tower and drove a diamonite spear through his chest. The last thing Finn saw was Marceline's head hanging out of his target's closed fist.
Finn suddenly sat up back in the field with Marceline and Marshall Lee and was panting like he had just run five miles in half as many minutes. He was covered in a cold sweat but knew it hadn't just been a nightmare. He had watched Marceline die. He would never let it come true. Then again that would just make the same thing happen. He also wondered why he had needed Ice Wings to fly.
"You okay?" Marceline asked putting a hand on Finn's back.
"Fine," Finn lied. "I'm fine."
"That was a pretty intense dream huh?" Marshall Lee asked.
"Yeah," Finn said. "Did I talk in my sleep?"
"You were screaming something incoherent about staying away from a man with a soul patch," Marceline said.
"Then you were screaming about not letting heads roll," Marshall Lee said. "Her head, to be specific."
"You want to talk about it?" Marceline asked.
"Not right now," Finn said flicking his eyes at Marshall Lee.
"That's okay," Marshall Lee said, knowing he wasn't allowed to hear. "I should be going anyway."
Marshall Flew off and Finn waited until he was fully out of vampire hearing range. When he was Marceline waited patiently for Finn to figure out what to say.
"I once dreamt that you warned me that I would have to choose between the world or you," Finn said. "In my dream there were two towers. One made out of ice, the other made out of diamond. You were in the Ice Tower and the person that would end the world was in the diamond tower. The two were right next to each other but you were going to be killed at the same time the world ended and it was going to happen in five minutes. I had to choose so I sent an army of Ice Clones to the diamond tower while I went after you. I fought my way through the tower but the moment I found you an Ice Golem beheaded you with a diamonite axe. You didn't survive. I had told the Ice Clones to bring the diamond tower down and they did. All of them died but the target didn't. I tried to stop him but I was stabbed through the heart with a diamonite spear."
"That won't happen," Marceline said. "I'm not going anywhere."
Finn hugged her and she hugged him back. She could tell that he was more upset about this one dream than he had been about anything before. That was how she knew it wasn't just some dream.
"I'm not leaving you," Marceline said.
Finn knew she really believed that but also knew that she knew that it had been a real vision.
"I won't let you die," Finn swore. "I don't know who the target was. I never really got a good look at him, or her."
Finn looked around and saw that there were three Bloodrunners surrounding them. He stood and Marceline did as well. Before anyone could do anything all three knelt. Finn looked at Marceline for an explanation but she was as much at a loss as him.
"Lord Finn," the Bloodrunner in front said.
"Lord Finn?" Marceline asked.
"We need your help to end our king," the Bloodrunner continued.
"Why would you want to kill your king?" Finn asked.
"He means to turn every person on the entire planet into a monster on Halloween," the Bloodrunner said.
"Why wouldn't you want that?" Finn asked.
"When true monsters still existed outside of the Nightosphere, we Bloodrunners were the most hunted species out of all of them," the Bloodrunner said. "If there were that many monsters we would be torn apart."
"What about the people that don't dress up?" Marceline asked.
"They would become Bloodrunners then get killed instantly," the Bloodrunner said.
Finn thought for a second then said, "If I kill him my dream won't be able to come true so I'll help. You're coming too Marceline."
"Deal," Marceline said.
The Bloodrunners stood and placed their hands on Finn and Marceline. Then they all teleported to a field with two towers in the distance. One was made out of Ice and the other was made out of diamond. Finn held his hand out and the Ice Tower exploded.
"Don't need that," Finn said. "I assume your king is in the diamond tower."
"Yes," the Bloodrunner said.
Finn and Marceline flew to the tower and were greeted by Bloodrunners. Finn tore the Bloodrunners apart as they climbed the tower. By the time they reached the top floor Finn was dripping blood. He kicked the doors open and they saw the King sitting on his throne. Marceline instantly started growling and Finn was lucky to be able to restrain his own anger. On the throne was a vampire that Finn didn't recognize, but standing next to him was none other than Ash. Finn hated Ash and had wanted to tear his throat out for years. Finn was beginning to believe that this was his lucky day.
"Hey Mar Mar," Ash said.
"Ash," Marceline said then glared at the vampire. "You."
"Who's the stiff?" Finn asked without taking his eyes off of Ash.
"He's the Vampire King," Marceline said. "I became Vampire queen because he raped me."
"Imagine that," Finn said. "Guess this really is my lucky day."
As he said this his teeth all turned into fangs and his pulled out his Axe-guitar. Ash pulled out a pair of hatchets and sprinted at Finn. Finn handed his axe to Marceline and threw three knives at Ash. Ash dodged them all but Finn had tricked him into running right into his fist. Ash soared through the air and landed in a heap next to the throne. The Vampire King could clearly see that Finn's fist had smashed into Ash's face so hard that his skull had caved in to the extent that pieces of it were sticking out the back of his head.
"Ouch," the Vampire king said. "You're strong, fast, and clever. But that trick won't work when your enemy isn't afraid to take a knife."
Finn smirked and took his Krav Maga position. The Vampire King saw that Marceline clearly believed that Finn had the fight beaten already, but he had a few tricks she didn't know about. For one he knew Krav Maga as well. He mirrored Finn's stance, but Finn was unaffected. In Krav Maga you weren't supposed to show any emotion. Finn was clearly a black belt. Finn waited patiently for the Vampire King to attack. When he did Finn easily out paced him and within minutes the Vampire King couldn't do anything but take punch after punch. Finn even lost track of how many he landed but after a few minutes the Vampire King finally fell back onto the throne and Finn pulled out the one knife that he had made especially for vampires. It was wood but was sharper than most of his other knives. The Vampire King's eyes widened and he tried to get up, but Finn threw the knife and the Vampire King sat back down with the knife sticking out of his forehead.
"Nice job," Marceline said.
"Thanks," Finn said turning back to normal. "That felt good."
"I can't believe you killed Ash in one punch," Marceline said.
"He didn't have time to use a spell," Finn said.
"Wrong," Ash said appearing in front of them with Finn's wooden knife.
"That's cute," Finn said smiling. "But you should have stayed dead."
Ash sprinted forward and tried to stab Finn in the heart with the knife but it exploded on Finn's skin thanks to the ring. Finn picked Ash up by the front of his shirt and held his hand out behind him. Marceline handed him his axe and Finn used it to split Ash from the head to the waist. He didn't go all the way but Ash was still dead and bot halves of his heart were spraying blood all over the place.
"Gross," Marceline said.
They walked out of the tower and told the Bloodrunners that it was over. Then they flew back to Finn's house. When they got there Marceline said her goodbyes and went back to the Nightosphere. Finn wasn't too happy about it but didn't try to stop her. When she was gone he ate a couple apples and then sat in front of the TV. He was content and believed that he had stopped his dream. Unfortunately he was wrong.
THE END
