Chapter 18: The war of Ooo part 2

The slashing and clashing of steel filled the ruined castle and the surrounding area. Warriors from both sides fought with everything they had. This was the final battle. The end game. The final deciding factor to the fate of Ooo. However, once Fin and his friends at to strike at The Lich, he simply grinned and sidestepped them.

"Foolish mortals. I have years of experience you'll never hope to achieve." He taunted. Fin sneered and charged. The Lich grinned and prepared a ball of magic in his hand, ready to meet the young boy and end his life. However, his attention was fully on Fin, allowing Phoebe to blast him in the face with a fire ball. This stumbled the undead king and disoriented him. Fin and Marceline used this to their advantage to hack and slash at him. However, The Lich was still a mighty foe in his own right, and managed to dodge the blows, recieving only cuts to his clothes. "Hmm... I will admit, your attacks are most impressive. I'll be sure to keel your heads as a reminder of your skills."

"Not gonna happen ya rotten slug!" Jake said as he slammed a massive fist into The Lich, knocking him into a wall. Then, with a battle cry, Bonnie tried entering the fray, only to be stopped by Jake. "Woah, easy there, princess. You should get to safety." Bonnie frowned and pulled something out of her lab coat and aimed it at The Lich, who had recovered and was preparing to blast them with more magic. She quickly shot her odd gun and a stange, orange colored goo spewed out. It coated The Lich and stopped his magic dead in its tracks.

"What?! What trickery is this?!" He bellowed, trying to get the goo off, to no avail. Bonnie smirked and placed a hand on her side and popped her hip cockily.

"I call it the amber launcher. Take a guess what it shoots." She stated. The Lich looked at his hand and grimaced at the infernal goo that had trapped him for nearly a millennia before. He quickly tried to dispose of them before their plan reached fruition, but they were quicker to the draw. As soon as he readied a blast, Phoebe shot it out of his hand. Fin and Marceline sliced at his legs to bring him down and allowed Bonnie to coat them in amber. "No! You will not beat me! I will not allow it!" He tried summoning his minions to his aid, but saw that, as he became encased in amber, his hold on them grew weaker. His minions became sluggish and some returned to death completly. As a last ditch effort, he readied up a more powerful spell, one that would crack the very earth. He rose his hand up and prepared to slam it into the ground. However, Fin jumped in his way and used his sword to block the blast. The Lich's eyes widened as his magic erupted before it hit its mark and blasted the boy back. Fin groaned in pain, but he was mostly bruised from the impact. He ignored this pain though, because he saw that Bonnie had reloaded her gun and was aiming it right a The Lich. Fin grinned and waived goodbye to the Lich as bonnie shot him. "NOOOOOO-" The amber covered his entire being, leaving a screaming visage to be immortalized for all time. Just then, all the thralls the lich had risen began to crumble and fall. The sounds of battle died out and was replaced by calmness.

"We... we did it..." Jake mumbled. Everyone grinned and began to cheer and celebrate their victory. The battle was over. They had won. Bonnie sighed and dropped her gun.

"Thank goodness that worked."

"How did you know the lich would return?" Phoebe asked.

"I didn't, i just have lots of contingency plans in place." Marceline gently punched Bonnie on the shoulder.

"Its a good thing you're such a smart cookie." Bonnie blushed a bit and nodded.

"Wow... that's was so easy." Phoebe mentioned.

"That's because we all worked together. We did this as a team. Right Mike?" Fin glanced at Mike, who was standing in front of the Lich's amber prison. "Uh... Mike?" Fin walked over to Mike, who was holding his scythe tightly in his hands. As if he was... waiting for something to happen. "Dude, come on. He ain't getting out of there. This is a time to celebrate." Mike didn't answer. He simply stood there, standing a vigil. It was then that Fin felt something... off. It was a dark feeling he didn't like. The hairs on the back of his neck stood on end. "Guys! Its not over! something's about to-" The sudden burst of amber shards erupted from the Lich. Then, loud, demonic laughter filled the room. After recovering from the shock, they focused their eyes on the Lich... but something was horribly, horribly wrong. The lich looked different. He was larger, more menacing. His horns were twice the size they normally were and weren't cracked or broken, his eyes were a blazing, evil blood-colored red. His mouth was filled with rows of jagged teeth. The pure mass of the rest of his body nearly doubled what it was and his fingers were sharpened daggers with spiraling balls of demonic magic housed within. "What the..." Was all the horrified teen could say.

"THIS! THIS IS THE TRUE POWER GRANTED TO ME! I AM UNSTOPPABLE! I AM INVINCIBLE! I! WILL! DESTROY YOU!" The Lich king bellowed and follwed this with insane laughter. Fin looked around. His friends were cowering in fear. Not that he blamed them. Fin had never seen such a horrific sight. He gripped his sword with shakey hands and gulped. But a gentle hand on his shoulder made him stop and look.

"Ready to put this guy back in the ground, Fin?" Mike said with his trademark smile. Fin gave a small smile back and rebuilt his courage. "We do what we need to do, because it needs to be done, even at the cost of our own safety. Because in the end..." He looked around at all the friends he made during his journey. He closed his eyes for a moment and seemed to be remembering something "In the end, they're all that matter." Fin smiled and nodded.

"Family. Friends. We do it for them." He replied.

"Now lets kick this zombie's ass, shall we?" They grinned at the Lich. Two hero's standing at the end of oblivion. Staring down the greatest evil they had ever fought. Two hero's weapons gleaming in the sunlight of a brand new day. They charged the lich. When suddenly... BOOM

In the darkness

Fin was confused. He didn't know where he was or why. He looked around and all he saw was darkness. Darkness... Darkness... It swallowed him, engulfed him. He tried to scream but it was devoured by the nothingness. It was maddening, but then he saw a figure not too far away... It was large, hulking, and menecing. It was the lich king. Fin gripped his sword firmly and charged the lich king, who didn't move.

"Come, boy." He taunted. Fin swung, but the lich king dissapated at the last second. He looked around and saw him a few feet away. " Too slow, boy." He growled and charged again. He sliced at the Lich king but again, he dissapated and reappeared a few feet away. "You are weak" Fin sliced again. The Lich king moved again. "You are nothing." Slice. "Worthless." Slash. "You are no hero. Your friends will be cast into oblivion. They will die, and so will you. All you do is for nothing. You cannot stop me, and you cannot save your friends." Fin growled, face red with rage.

"SHUT UP!" Fin sprinted to the Lich king and lunged. This time, he didn't disappear. Fin buried his sword deep into the Lich kings chest. Nothing happened at first. Fin looked at the Lich king, who seemed frozen to the spot. But then... then a second face appeared over the Lich kings shoulder. It was another Lich king.

"Good job Fin..." The head said. "You struck true and killed your target with deadly efficiency. Shame that I wasn't the one you impaled."

"W-wha...?" Fin mumbled. The darkness started to fade away and color began to return to his world. The first thing he saw was the Lich king, but he was perfectly fine and uninjured. However... he was standing behind someone and that someone... was Mike. "No..." Fin slowly looked down at his sword. He slowly began to look up in fear of what he already knew. His hands shook violently as the Lich King laughed. Fin had ran Mike completly through with his sword. Blood poured from the wound and collected in a puddle under Mike's feet. "No... No, Mike... I... I didn't... Didn't know..." He babbled. But Mike didn't look betrayed. He didn't look scared. He simply kept the smile he always wore on his face.

"Fin... I have to tell you something..." Mike choked out, though blood.

"W-what...?"

"The reason... I came to Ooo..." He started. "Was to find someone... someone special..." He took a few deep, ragged breaths. "Someone... someone equal or greater to my own strength... I knew exactly who I was looking for... I was looking for you."

"M-me...? No... I've seen you in action... you're... well, superhuman! I'm nowhere near that..." Mike chuckled a bit.

"Well... look what you did to me... I got about... I dunno... five minutes left till I bleed out? Give or take..." Mike chuckled more but had to stop himself because made him choke on his blood. "Fin... you don't know it... But you're stronger than you can ever imagine... Wanna... wanna know why...?" Fin gulped but Mike didn't let him reply. "We're not superhuman Fin... We're just human... We're more than anyone realizes..." Fin didn't understand. But Mike still wasn't done yet. "However... I will admit... to one thing..." Fin blinked a bit as Mike rose his head up and their eyes met. Fin saw the smile finally fade from Mike's face and a look of total seriousness replaced it. "I am extremely pissed off." Before Fin could react, Mike grabbed ahold of Fin's sword by the blade. The blade shimmered and almost seemed to glow. But that wasnt the most surprising part, it was when Mike took the blade and drove it the rest of the way through his chest. He did not do this for no reason, however. Mike knew the Lich king was still behind him, and driving the blade through his chest punctured the lich king as well, causing bellows of rage and pain to erupt from the undead lord. Mike pushed Fin away, causing the sword to be finally removed from Mike. He groaned a bit but picked up his scythe. "ugh... Five minutes... More than enough time to deal with you." Mike gripped his scythe tightly and charged the Lich king. He raised his scythe high and prepared to drive it into the lich, but the lich king simply grinned. Fast as lightning, the lich used his razor sharp claws to sever Mike's left arm completly from his body. Mike looked at it in shock as it fell to the ground. Mike dropped to his knees and stared at it while the lich king laughed.

"ALL THAT BUILD UP AND FOR WHAT?!" He bellowed. Fin stared in shock. But then... at that moment... he felt something... something deep inside of him... waking up. He looked to Moke's scythe and noticed the shimmering glow that constantly followed it then looked to his sword. When Mike touched it... He picked up his sword. "YOU DARE APOSE ME, MORTAL?! YOU ARE NOTHING! I AM ETERNAL! I AM-" the Lich king was quickly shut up by a swift slap to the face. The lich king was shocked.

"That was my favorite arm you ass." Mike said with a growl. The act of the slap wasn't what surprised the lich king. It was the fact that Mike slapped him with his own severed arm. Mike grumbled as he pressed the severed end of his arm to his stump. He groaned a bit as a golden glow surrounded the arm. A few moments later, he let go and the arm seemed reattached. He flexed his arm to make sure. "There we are... good as new" Mike then glanced behind the Lich king. "Took you long enough."

"What?" The lich king quickly turned around, but his head was instantly cut off when he did. Time seemed to slow down as everyone beheld the golden warrior, Fin, wielding a beautiful amethyst sword. The lich king fell to the ground and Fin finished him off by driving his sword into his chest. At long last, the Lich king was finally, truly, slain.
