Finn kicked down the doors to the weapons factory, sword drawn and eyes ablaze. It was, as expected, long abandoned. Parts of missiles lay askew and rusted among the broken conveyor belts and ground, and the cruel force of time allowed the dying weeds to make the factory their home.
From the rays of sunlight entering from the roof, Finn could see several banners of his enemies flag, multiple black stars on a background of solid blue, the flag of the terrorist group, RUON.
He saw several RUON Plasma Rifles line the walls, but the troops themselves were nowhere to be seen, nor the man he was looking for.
"I know your here, coward! Come out and face me!" the young hero screamed before kicking down a rusted door near the back. The large room behind the door was more nature then indoors now, the floor overrun with grass and wildflowers, and only the foundation of the ceiling remained.
"Where are you, Penn!?" Finn screamed out before feeling a hand on his shoulder.
"I'm right here, brother." he heard Penn say before delivering a punch to his lower back, sending him flying to the ground and sliding across the ground.
Before he got up, he looked to his side and saw a small, red wildflower right next to his face. He let out small chuckle as he was reminded of a happy moment right before this whole mess started.
Finn sat in the grass, looking upon the rolling, green hills. The scent of fresh grass entered his nostrils as he took a deep breath through his nose.
He looked to his side and saw a delicate, red wildflower. He picked it and twirled it in between his fingers, sighing.
The flower reminded him of himself. Sure, among the grass, it was peerless, tall and beautiful. But as he looked around, there were no other wildflowers in sight. Sure, it had the grass, but it would no nothing about it's own kind.
He laid back and threw the small flower in the air, letting the lonely plant be carried away by the breeze. He closed his eyes. He was turning 18 today, yet he had never met even a single human. The closest thing was Susan Strong, but he had found out later she was a Hyooman, just like the rest of her peers.
He was surprised when a grey, slightly wilted flower the same size of the one he just threw in the air landed on face.
He heard a mischievous giggle behind him, and he suddenly realized who it was.
"Hey, Marceline." he turned around to greet his undead friend, who exited her state of invisibility and flashed a rocker sign. She was wearing the same outfit she had first met him in, a grey tank top, blue jeans, and red boots, and she held a red umbrella above her head.
"Hey, Finn. Just come to see how my favourite weenie was doing on his 18th birthday."
Finn sighed. Marceline looked worried.
"What's wrong, Finn? You're officially a man today, most guys would be ecstatic."
Finn looked down and sighed, "Well, it's just I've never met a single human before, and I'm already 18. What if I'm an old man before I meet another human? What if I die before I meet a human? What if- what if-
Finn sniffed a bit and Marceline pulled him into a small hug, "What if all the humans are dead, Marcy? What if I'm the last one?"
Marceline punched him in the arm, "Hey, c'mon! Stop being such a weenie! You'll find another human one day, and besides, I used to half-human half-demon before I was turned into a vampire, so I count a little right?"
Finn stood up and dusted the grass off his shirt, "Yeah, I guess, but only a little."
They laughed together and Marceline picked him up, "Lets go, hero. You're going to be late to your own party if we don't get going!"
Finn and Marceline landed near the Candy Kingdom Castle's giant, gingerbread doors. As they entered, PB, Jake, Rainicorn, and all their other friends were piled near a TV, all with a look of concern on their face.
Finn and Marcy walked over to the group.
"What's wrong, Jake?" asked Finn. Jake looked at his brother with concern in his eyes.
"Finn... you need to see this." Jake said with worry in his voice.
Jake stretched out his arms and pulled up a chair for his brother, who had a seat in front of the T.V. screen, with Marceline floating behind him.
Princess Bubblegum spoke a voice command to her self-created T.V., "Play back last broadcast."
The gadget did what it was told, making a whirring sound before it played. On the screen, their was dark dingy room, and nailed to the wall, was a navy blue flag with a number of black stars on it, which Finn didn't bother counting.
Suddenly, a figure stepped on screen. He was wearing a sleeveless, navy blue shirt under a black combat vest, an around his neck was a silver pendent and dog tags.
On his muscular arms were black, fingerless gauntlets, he also large tattoo of black star on his right arm.
He was wearing a gas mask that hid his face, although you could see his golden hair spilling down to his mid-ear, and it looked shockingly Finnish, even thought his went down to his shoulders, his bear hat no longer containing it.
"This is a message to the people of the Candy Kingdom." the figure said, pointing at the camera,"-well, more of a message to you, Bonnibell, because knowing that your Kingdom is comprised of soft cowards that implode upon the first sign of dang er, you probably will be intercepting this broadcast,"
Finn looked at Bubblegum, who looked like she was struggling to hold back tears.
The man continued "-but that's fine, because we're not terrorists, we're freedom fighters, and we well avoid the deaths of citizens tyrants like YOU enslave..."
"PAUSE!" cried out Bubblegum, and the video stopped for a second.
Finn and everyone else looked at her as she grabbed the young Hero's shoulders, "Finn, whatever comes on the video next, remember that that man is a filthy liar. He and his friends HAVE and WILL kill to force their ideals upon the people of Ooo."
Finn nodded solemnly, "Okay Bubblegum, I promise."
She sighed, "Continue..."
The video once again picked up, "Anyway, either you surrender your Kingdom to R.U.O.N., or me and my men will storm your castle, and I will personally slit your pretty pink throat. I want you to send a messenger to Ripper's Mountain, there we will meet to discuss your response."
The man looked closer at the camera, "-and I want the messenger to be your precious little slave and champion, Finn the Human."
Finn's eyes widened, and he certainly wasn't prepared for what would happen next, "If you're watching this Finn, I look forward to meeting another human-"
Finn shot out of his chair at this point, Marceline and Jake grabbing his arms.
The man peeled off his gas mask and threw it to the side, revealing a face strikingly similar to Finn's, besides the fact he had gruffer features and a 5''o'clock shadow.
"-and my dear little brother."
The video then cut off, but Finn wouldn't have known that, because as soon as the words 'little brother' left the man's mouth, he broke out of Jake and Marceline's grip, throwing them to the side as he dashed out the room.
Jake looked over to his wife Lady, who was comforting their crying children.
"Don't worry, I'll get Uncle Finn back." he whispered to his children in Korean, before running after his distraught brother.
Marceline was already flying after Finn, however, who was already out of the Candy Kingdom and running through the plains. Marceline finally caught him and tackled him into a tree, dropping her umbrella, but fortunately being protected by the tree's shade.
"LET GO OF ME, MARCELINE!" he screamed at the top of his lungs, but Marceline still pinned his arms and legs to the ground.
"Not until you calm your ass down!" she responded.
Finn then pulled his leg out from hers, kicking her in the stomach and sending her flying off of him. She landed near the edge of the shade, but her forearm still landed in the sun, causing to instantly swell up with blisters.
She pulled it in to the shade and hissed in pain. Finn ran over to her, "Oh Glob! Marceline did I hurt you?"
"Yeah..." she said holding out her blister covered arm.
"I'm so sorry..." he muttered sadly, while taking some burn ointment out of his bag.
"It's okay, Finn. I can't imagine what you're going through right now. I mean, the only other of your species, and he's a terrorist? AND your brother?"
This made Finn even more depressed, "Let me see your arm."
She stuck it out, and he rubbed the cream on it, "Luckily, I still have some of this from before I broke up with Flame Princess."
"Why did you guys break up anyway?"
"Well, everything was going great for a while. She started to learn how to control her emotions so she wouldn't burn through the earth when we kissed, she even learned to turn down her heat so I didn't have to use a flame shield spell on myself to kiss her. She was still a beginner, though, so I would still sometimes get burned. Thus, the burn ointment."
For whatever reason, Marceline felt a tang of jealousy when she imagined Finn and Flame Princess kissing. She just ignored it, though. "So, what happened?"
Finn finished applying the burn ointment, "Well, she still had one emotion she didn't train: jealousy. She told me I should stop rescuing princesses and hanging out with you and PB and start spending more time with her. I told her she was being ridiculous, and then she called me dirty cheater and broke up with me!"
He tore off part of his shirt and wrapped it around her arm. All was silent for a moment.
"Marcy? Do you think that guy's really my brother?"
"I dunno, Finn. He looked a lot like you."
A giant Jake ran up at that moment, shrinking back to regular size and gasping for breath.
Jake hugged his brother, "It's okay, Finn. I'm for ya, brother."
He patted Jake on the back, "Thanks, bro."
Marceline picked up her umbrella while Finn and Jake stood up, "Jake do you think that guy is really my brother?"
Jake shrugged his shoulders, "I dunno. He could be your son from the future, a clone from a mad scientist, a rogue android, an artificial body inhabited by the Lich built from your DNA, your..."
Finn pressed Jake's cheeks together, his antics slightly cheering him up. "That's enough crazy theories out of you, mister."
"What now, Finn?" asked Marceline.
Finn punched his palm, "I tell you what we do now. We go to Ripper's Mountain and kick his buns until he explains what in the name of Glob is going on.
