Warning! I do not own Adventure Time or any of its characters. Before we begin I have an announcement to make. A good friend of mine who used to read these chapters before I posted them and provide feedback has moved away. His ideas and concepts were instrumental in the development of this story and his presence will be missed. I'd like to dedicate these last few chapters in his honor. Now without further delay; the chapter 9.
"Everyone knows the plan?" PB asked as the three friends approached the Frost Prince's lair.
"I provide backup while Marceline uses the necklace to try to spark Roy's consciousness….." Finn replied.
"…..and once Roy regains control you inject him with your modified version of the cure, destroying the Frost Prince forever." Marceline finished.
"Good." PB said satisfied. "Come on we don't have much time."
The trio crept through the tunnel until they reached the throne room. Except this time it looked completely different. The frost bomb still sat in the center of the room, however surrounding it was ice sculptures depicting Marceline and Roy's adventures from when they first met all the way up to Roy's accident. The Frost Prince sat in his throne watching the group enter the room.
"Tell me Marceline," He said as he rose to his feet. "Do you like my work?"
"Where's Jake!" Finn shouted glaring at the Frost Prince.
"Jake, Jake, Jake… Ah yes!" Frost Prince exclaimed snapping his fingers. A section of the wall behind the throne slid away to reveal a hidden room. Jake was wedged between an old guitar and a book shelf. "As you can see your friend is unharmed. However, all that can change if you choose to stand against me." He explained as he walked over to the frozen dog. "So I'll give you all a choice. If you join me you and your friend here will live. If you choose to fight me you shall all perish." Frost Prince grinned as he placed a hand on Jake's head. "I'm a fair man so you've got….. one minute to decide."
"I refuse to join a coward like you Frost Prince." Finn replied drawing his grass sword.
"So I take it that's a no then?" Frost Prince asked still grinning. "What a pity. I guess I'll have to have my new lieutenant here destroy you then."
"New lieutenant?" Finn replied looking around. Suddenly the frozen statue of Jake took a step forward. "Jake!"
"Your friend can't hear you!" Frost Prince laughed as Ice Jake advanced towards Finn. "The ice has control now."
"Finn, you handle Jake." Marceline said as she pulled out her Ax Bass. "I'll take care of Roy."
"So you think you have what it takes to defeat me?" Frost Prince asked still grinning as he created two ice swords. "Or are you still counting on Roy to come back?"
"I know he's still in there!" Marceline exclaimed swinging her ax. Frost Prince rolled to avoid the blow.
"Now it's my turn!" He replied kicking Marceline into a sculpture of her and Roy fighting a horde of skeletons. The sculpture shattered around her as her ax slid across the room.
Meanwhile with Finn
"Come on Jake, we're bro's remember?" Finn asked dodging Jake's latest attack. The ice on Jake's hands grew into daggers. Finn used his sword to block yet another attack.
"Keep him distracted Finn!" PB shouted from behind a nearby sculpture. "I've got an idea."
"Uh,OK." Fin replied nervously as he rolled to the side. "Hey Jake, remember all those times we beat up the Ice King?" Instead of responding Ice Jake charged forwards. Finn moved out-of-the-way at the last minute causing Jake to crash head first into a sculpture. Finn looked over to see Princess Bubblegum sneak over to the hidden room and grab Roy's old guitar. Finn's attention returned to the fight as one of Jake's daggers severed a strap to his backpack. Finn countered with a sweeping kick that knocked Jake over and chipped a bit of the ice on his head. As Jake rose to his feet PB smashed the guitar against his head shattering the ice.
"Oww!" Jake exclaimed rubbing his head. "What was that for?"
"The Frost Prince froze you and reanimated your frozen form as his lieutenant." Princess Bubblegum explained. "We had to break the ice to free you."
"Did you have to hit me so hard?" Jake replied still rubbing his head.
"We'll apologize later but right now we have bigger problems!" Finn exclaimed pointing at the Frost Prince who was busy arming the frost bomb.
"Fools! You're too late to stop me." The Frost Prince laughed as the count down was activated. "The bomb's set to go off in five minutes and there's no way to stop it! Soon my victory shall be complete!"
"Hey Frost Prince! Catch!" Marceline shouted as she chucked a severed ice head of Roy at the Frost Prince. Frost Prince turned just in time to see his own face before the chunk of ice hit him right between the eyes knocking him to the ground.
"You just don't know when to quit do you?" Frost Prince growled getting back up.
"Bring it on!" Marceline exclaimed retrieving her ax. The Frost Prince created an ice sword and charged forward. Marceline blocked the blow with her ax. Seizing the opportunity Jake wrapped himself around the Frost Prince immobilizing him.
"No!" Frost Prince exclaimed struggling to break free. "I can't be defeated! HEwould destroy me!"
"I can't hold on much longer!" Jake shouted as Marceline pulled out the necklace. Suddenly the Frost Prince broke free of Jake's grasp and plowed into Marceline, sending her flying into an ice sculpture of the day Roy and Marceline met. Before Marceline could recover Frost Prince was already standing over her, sword raised for the final blow. All Marceline could do was raise her hand in a futile attempt to ward off the attack, the necklace in plain sight. As the Frost Prince's eyes gazed upon the trinket something deep inside of him awoke. In the darkest corners of his mind another consciousness began fighting for dominance.
"Marceline?" Roy asked hesitantly as his eyes changed to blue once more.
"Finn hurry!" Marceline exclaimed. "Get the cure!" Princess Bubblegum quickly tossed a syringe full of blue liquid to Finn who injected Roy. Roy doubled over in pain as the serum began to take effect. His eyes began alternating between red and blue.
"You fools!" The Frost Prince's voice exclaimed. "You have no idea the chain of events you've unleashed! This isn't over! Not by a long shot!" And with that Roy collapsed.
"Roy!" Marceline exclaimed leaning over his unconscious form. His eye's slowly flickered open.
"What happened?" Roy asked looking around. "Frost Prince….."
"He's gone dude." Jake explained. "My bro Finn here injected you with your sister's version of the cure and now that wacko is gone for good."
"I'm free!" Roy laughed. "I'm finally free!"
"He's still got a case of poo brain." Jake whispered to Finn who nodded in return.
"Guy's we still have a problem!" PB exclaimed looking at the bomb timer which had reached the one minute mark.
"Roy can you deactivate it?" Marceline asked.
"There is no way to deactivate it." Roy said shaking his head. "It was designed to go off no matter what."
"So there's no way to stop it?" Finn asked concerned.
"There is one way." Roy replied turning towards Marceline. "Do you trust me?"
"Oh course!" Marceline exclaimed. "What kind of question is that?"
"Then you need to get my sister and you friends out of here." Roy said grabbing Marceline by the shoulders. "I think I can use what's left of my powers to create an impenetrable ice barrier inside the cave trapping the explosion."
"How are you getting out?" Marceline asked skeptical.
"Just trust me Marceline." Roy assured. "I'll be right behind you."
"You better be." Marceline replied as she grabbed Finn, Jake and PB and flew out of the cave." Once she left, Roy turned back to the bomb.
"Well I guess it's just you and me." Roy sighed. "This is my one shot at redemption." Roy began forming a giant ice dome inside the throne room.
"I've done so much evil," Roy muttered as the dome closed above him. "I've caused so much destruction. I hope Death is merciful."
Meanwhile outside the cave
"What's taking him so long?" PB asked as starring at the mouth of the cave. "He's running out of time!"
"I'm going back in to look for him." Marceline said flying back into the cave. Marceline raced back toward the throne room only to be stopped by a clear barrier of ice.
"No!" Marceline exclaimed when she saw Roy sitting inside the dome next to the bomb. "You promised!" Roy must have heard her somehow because he opened his eyes. He gazed upon Marceline one last time before mouthing the words "I'm sorry."
The bomb went off.
There was a flash of white light.
And Marceline lost consciousness.
Well there you have it, the final battle! Don't worry, we still have one more chapter left before this story is officially ended. And once again I'd like to thank those who've stuck around and reviewed/followed/favorited this story. If not for them this story would have died long ago. I'm sorry it took so long to update, however the final chapter should be up by the end of the day if not tomorrow. Thanks for reading and for those who already haven't check out Teller16-djb's Mixed Dimensions trilogy.
