AN: Well this took a million years. Freaking college.
The Ice Warriors stepped forward, hissing yet again as their shielded eyes took in the Ice King before them.
Inside the TARDIS, the group of six watched as the aliens approached the blue man.
"So." Simon said, tapping his fingers together in front of him as he slowly backed away from them. "You guys, uh, here to have a party or something? I mean I don't remember scheduling one but that seems like something I'd do. Or do you just wanna, like, take me up in your spaceship or whatever."
The warriors did not respond, instead raising their guns so that they pointed at the wizard.
"Whoa hey now! What'd I ever do to you?"
Again there was no response, but the warrior in front fired his weapon. The residents of the TARDIS watched confused as the Ice King bent over in pain, despite there being no visible effect from the gun.
"I don't get it." Jake said. "What's going on?"
"Of course!" The Doctor muttered, snapping his fingers. "A sonic probe. They're bombarding him with sound waves!"
"Oh but Doctor," Zoe said, " the last time we saw Ice Warriors their sonic weaponry was lethal- it killed instantly!"
"Aye she's right Doctor!" Jamie said. "But look at the man, he's still standing."
On the screen, Ice King was clutching his head before he gave a furious shout and blew a gale of icy wind at his attackers. Slowly a layer of frost covered the three assailants, and they were frozen in place.
"Phew!" Ice King said to himself. "That was getting annoying."
Not a moment later, the three warriors took a sudden step forward and continued moving as if nothing had happened. They all Rose their guns again and this time fired the weapons in tandem. Ice King let out a strangled scream and doubled over in pain. The sound waves created cracks in the surrounding ice, pieces of the walls and ceiling breaking off and crashing around them. Simon forced himself to fly by his beard and retreat from the room, barely able to keep aloft as the warriors slowly continued to follow him.
"Should we...do something about this." Finn asked.
"Yes!" The Doctor said.
"No!" Came Bubblegum's response.
The two turned to each other with bemused expressions.
"Yes!"
"No!"
"YES!"
"NO!"
"Oh, why not!"
"It's just Ice King." Bubblegum replied. "If he's gotten himself in trouble with these guys, that's not our problem. The comet is! And we need to take care of it while we still can!"
"The Ice Warriors may very well want to KILL him! I'd already gathered you're not very fond of him but I highly doubt you want that."
Bubblegum huffed, as Finn made his own decision and took out his sword once again.
"Come on Jake." He said. "Let's go save his butt."
Suddenly, however, the console room shook violently again, everyone grabbing the console to keep steady.
"Oi, Doctor what's happening!?" Jamie asked.
"I don't know Jamie!" The Doctor yelled, he moved around the console and found yet another screen. "It's like she's trying to take off- or, rather, trying not to take off, er-"
"Oh do make sense, Doctor!" Zoe yelled over the racket of the shaking.
"It's like something's pulling her, trying to force her to dematerialize, but she's resisting."
He looked from the console to the door repeatedly and shook his head.
"Oh...Zoe, whatever the Ice Warriors want here it can't be good! I'm trusting you with the TARDIS!"
"Well what do you mean?" She asked.
"I'm going to go outside and see if I can't find out what they're doing here, you have to help the TARDIS resist whatever's pulling it. If not it could end you up who knows where, understand?"
"Yes, I understand!"
"Try your best to stabilize her and keep her grounded here!" He emphasized before heading to the door. "Jamie, stay with her in case she needs anything!"
Jamie nodded as Bubblegum rushed after the man leaving the box.
"Wait!" She shouted, exiting close after him, "WHAT ABOUT THE COMET!?"
Finn and Jake shared a glance, before Finn ran out after them as well.
"Jake, stay here with them in case anything super crazy goes down!"
"On it!" The dog said, stretching over to the console as Zoe looked around and pressed buttons and switches meticulously.
"Doctor!" Bubblegum shouted, "What about the-!"
"Shh!" The man preempted her, exiting the Ice King's room and coming to a large staircase. At the very bottom were the Ice Warriors, apparently following the Ice King's tracks and taking no notice of those above them.
"What about the comet?!" The pink monarch whisper-yelled.
"One problem at a time." The Doctor said sternly as Finn joined them. Slowly, he led them down the stairs, and into a long hall.
"Oh I remember this." Finn said. "This is where he holds his fashion shows."
The Doctor looked around the hall in distress, the walls each housing many different openings and passageways.
"Which way did he go!?"
"Heyyy..." Came a low whine from one of the passages, and the three walked over to see yet another staircase, with the Ice King lying in a heap at the bottom.
"I fell down the stairs." He said matter-of-factly as the other three quickly descended the stairs and helped him to his feet. "Don't you judge me. Not until you try flying while trying to block out that stupid noise they make."
Suddenly said noise blasted through the wall, as did the Ice Warriors, stepping into the room with their weapons trained on the colorful foursome.
"Yeah, like that!" Ice King said, as bits of the ceiling began to crumble yet again from the Ice Warriors' abuse.
"Would you STOP WRECKING MY HOUSE!" The blue man yelled, his voice furious. He was stopped in his tracks however as the weapons were leveled on him, quickly flinching back.
"Ssssssssstep away from the taaarget." The lead Martian rasped.
Finn, The Doctor and Bubblegum exchanged glances, before very slowly stepping away from the Ice King.
"Why is he the target?" The Doctor questioned. "What do you need him for?"
"Ssstep away from the target!" They reiterated, raising their weapons to the level of Ice King's noggin.
"I think... I think they want your crown." Bubblegum said hesitantly.
"WHAT!?" Simon yelled, flipping quickly back to anger, raising his hands in offense. "Ain't no way some green nobodies are comin' in here and takin' MY crown!"
"Ice King!" Finn shouted with equal fervor. "Give them the crown now."
"I don't wanna!"
Bubblegum sighed, before punching the jewel-encrusted object right off the blue mans head and onto the floor.
"Mm, yes, very good." The Doctor said. "Now let's step back, like the man said."
As they did so (Simon more reluctant than the rest), The Doctor leaned over to Bubblegum.
"Why do you suppose they want that crown?" He whispered.
"It's what gives the Ice King his frost powers." The pink monarch said.
The Doctor raised an eyebrow as the ice Warriors approached the crown, one leaning down to pick it up. Once they'd done so, they blasted yet another hole in yet another wall and proceeded to make their way out of it.
"No, no this isn't right..." The Doctor muttered. "We shouldn't let them take it."
Bubblegum scoffed.
"You're picking a really bad time to flip flop on things!" She hissed.
"I'm familiar with this species, if they want that crown for anything, it's likely as a weapon of mass destruction."
"So, we're totally stealing it back, right?" Ice King asked, the other nodding in response.
"Very likely, yes."
The Doctor looked over to Bubblegum for confirmation, and after a moment the girl gave a curt nod to Finn. The boy yelled out loud and ran up to one of the warriors, lifting his leg and kicking the crown out of their grasp. The creatures hissed loudly as The Doctor caught the crown, raising their weapons agains and firing on the blonde boy. With the point-blank blast, Finn was blown halfway across the room, holding his head in pain. Bubblegum knelt down beside him as the Ice Warriors collectively turned their heads to the Doctor, who shared their gaze for a split-second, before yelping and running off with the crown in tow.
The spot where he had been standing not a second earlier was blown away by the Ice Warriors weapons, and the three were following in pursuit of the Time Lord as quickly as was possible. The Doctor sprinted down corridors and corridors of ice, but he found himself getting quickly disoriented as walls and columns alike were blown apart around him, ice spraying everywhere. The Doctor found himself stepping on one particularly large chunk of interior, slipping and falling onto his back. Keeping a steadfast hold on the crown, the man stood up quickly and attempted to reorient himself. Looking around him, he quickly realized he had no idea where he was going or where he had come from.
Picking a random direction, The Doctor turned a corner only to come face to face with one of the Warriors.
"AAAGH!" The Doctor yelled, tossing the crown over his head in surprise. The crown flew to a nearby staircase and bounced downward. The sound of its descent rung out amongst the silence, and The Doctor looked from the staircase to the Ice Warrior then back again, before bolting down the stairs.
The Doctor flinched as the Ice Warrior's blast just barely missed him, top of the stairway was blown apart. Ice piled down on the top of the staircase as The Doctor finally reached the bottom of the staircase and picked up the crown. The ice blocking the top of the staircase left the room rather darker than it already was, and The Doctor noted that he couldn't see a way out as he patted himself down. His gaze fell to the crown in his hand, and he stared at it intently for a long while.
The Doctor fiddled with the crown, knowing he would likely regret what he was about to do, and yet he couldn't temper his curiosity. The room around him grew darker and darker as he brought the object closer to himself, before placing the crown atop his head.
"...Huh." The Doctor said, flexing his hand as nothing happened.
POWER-
Then suddenly, the visions came. Grotesque, multicolored creatures swarming around him aimlessly, all of his sense assaulted by some force-
FROST-
He was cold inside. Everything was so cold. Snow poured out of his mouth and his vision blurred, and he stepped haphazardly trying to remember where he was, and why.
"No." The doctor said. It hurt to talk. He reached up to remove the crown, but something compelled him to keep it on. He clutched his head in frustration. "No, I must fight-"
SAVE ME-
"I must fight! Jamie! Zoe!"
THE ICE WILL KEEP US SAFE-
"No, no no no no no-"
"I am the Doctor? Who is this? WHAT is this?"
GUNTER, NO!
"Gunter, no...!"
IT ACHES FOR OUR EXTINCTION-
And then suddenly, it was gone. The crown was torn off his head, and his vision immediately cleared to reveal the Ice Warriors. The Doctor hunched over, coughing up more slush before he brought his gaze up to the reptilian creatures. Without further warning, all three Warriors raised their weapons and blew The Doctor across the room. His ears popped, he could feel his bones rattling, and he fell to the cold floor with a thud. By some miracle, he'd retained consciousness, though it hurt to move.
"Ssssssssssss." Came the hiss of an Ice Warrior. "Yessssss. Thisss crown will be of much use to usssss. Marssssss will be ourssssss yet again."
The three left the room, and The Doctor didn't know if it was seconds or hours later when Bubblegum found him.
AN: I like to imagine Ice King's boss theme from "Why'd You Steal Our Garbage" as the background music for the chase scene. Also, some sort of super heavy guitar riff playing when The Doctor puts the crown on. For whatever reason.
