Cake's View

As soon as our sweet (y/n) had run off on us me Finn, Fionna and even BMO collected things we'll need and headed out the door after yelling at Jake a bit.

"Hey Cake can we ride on your back cause we're tired?" Fionna my dear sister asked.

"Yeah sure, just don't all of you go to sleep I need some help lookin' for our (y/n)." I was sure I could do it on my own if I really wanted to but knowing me I would become far too lazy and fall asleep and we can't have that.

"I'll stay awake with you Cake I don't really need to sleep I only do it cause I want to act like a really boy just like Finn and Jake." BMO replied.

Relieved I shook my head yes and using my amazing stretchy powers I stretched into a larger form and scooped everyone up and put them on little beds I also stretched out so that they can sleep on something other than my roundish back.

"Night everyone and thanks Cake." Finn called out then pulled up a blanket from his pack and laid it over his body and falling asleep.

"Yeah night Cake." Fionna yawned making her words harder to understand. She too pulled out a blanket and cuddled up next to Finn.

"Night honeys." I replied.

All that night BMO and I were on patrol searching the forest first because that was where she disappeared.

Now all though this might sound dog like, but I used my nose to follow a her scent. I followed it until I picked up two new smells.

"Hey BMO you smell that?" I whispered to it.

"No sorry Cake I can't smell but if you tell me what it smells like I might be able to help." BMO voice sounded sad then turned to it's normal cheery voice.

"Well it smells like smoke." I studied the ground to see the grass slightly brown.

"Fire maybe." It suggested.

"I think I know what." I announced and continued through the forest then turned left to the cliff where Flame Princess lives.

There I saw Flame Princess, Flame Prince and (y/n) threw the window laughing about something but I couldn't hear what.

I woke the others and told them about my discovery.

"We should probably set up camp and wait till morning before we go and get her, that'll give us enough time to figure out what we'll do." Finn commanded hopping off my back and walking to the trees and sat down just behind the bushes.

There he sat watching her intently with a protective look in his eyes, something tells me that this boy likes our (y/n).

We sat there for what seemed like hours but I only last like two minutes awake and then let my laziness overtake me and I fell asleep.

I woke at around three in the morning to screaming.

"What's going on?!" I screamed in concerned that someone was hurt.

"Lich!" I heard Finn scream as I turned around to see the Lich King carrying a frightened (y/n) under his bone arm. "Let her go."

"Yeah or we'll beat you up hardcore." Fionna added but with a hint of fear in her voice.

I looked to see BMO running back towards the direction of the tree house probably to get Jake.

I then see Flame Princess and Flame Prince trapped under and cage of deadly green flames.

I also saw (y/b/n) laying on the ground, dead.

"Hey Lich you put her down right now or we'll rip you apart bone by bone." I yell taking action and stepping out from the trees and stretched really big so that I might make him look small and scared but it didn't work.

"Out of my way you stupid feline." He boomed.

"Hey don't talk to her like that you stupid, bony, spineless, soulless, a**." (y/n) yelled trying to wiggle her way out of the Lich's arms.

"Stop squirming girl." He yelled tightening his hand into a fist.

This resulted in (y/n) screaming in pain.

"Don't you hurt her or so help me glob I will kill you." Finn threatened pulling his sword out from his pack.

"Enough I have wasted enough time," he told us then began to chant some weird sort of spell, "oh hanc sic et illam meam potens puella faceret illud ita erit ut faciat, quod praecipio detorquens eam in anima a tenebris et creans malum principem."

After he finished (y/n)'s eyes flashed dark red and her hair began to blow. He dropped her and let her begin to attack all of Ooo.

Earthquakes, tornadoes, volcanoes, tsunamis, any kind of possible natural disaster possible appeared around Ooo destroying everything making loads of Oooins die.

Finn fell to his knees crying he just couldn't attack (y/n). Fionna followed close behind along with me.

"Oh stop weeping really it's making me feel too good," she yelled. She looked so different than she used to. Her eyes were a full dark red, her hair glowed, she floated more often and her voice sounded dark more scarier.

"Y-y-y-ou." Finn began.

Fionna finally standing up and pushing her emotions to the side screamed. "Lich what in Glob's name did you do to her."

"Oh I just set loose the darkness in her, you see if you didn't fill her mind with all this hero stuff she would've already taken over the world, I merely knocked down the wall she created in her mind, she could've done it herself but this is better. Now she'll kill everyone and everything but me." he laughed and flew away and sat on a nearby tree.

"Alright guys pull it together maybe if we kill her the darkness will go away and she'll be normal again." I suggested.

"We could try I guess." Finn sobbed, still not wanting to hurt her.

We quickly devised a plan and flew into action. 

I grew big once again and stomped over to (y/n), who was now carelessly floating around happy with the destruction she has made.

"HEY that's ma home you're messing up." I sassed.

'Indeed it is, it's my home too but I think it needs improvement." She retorted.

"What do you mean improvement, you said it was perfect the way it is." I was trying to distract evil (y/n) so Finn and Fionna could get into position.

"You stupid cat, couldn't you tell I was lying." (y/n) yelled her voice dark.

"But I thought you said you never lied." I looked over and saw Finn and Fionna in position giving the secret signal.

"Arg you're so annoying." (y/n) said standing up so her back was straight. With a flick over her hand she sent me flying into a tree. Then lights out.

Third Person Point Of View

Soon after (y/n) sent Cake flying into a tree and knocking her unconscious, Finn and Fionna along with Marceline and Marshall Lee jumped out of the bushes and ran towards (y/n) swords blazing and axe basses swinging.

(y/n) turned around and a flame whip appeared in her hand. With one swat she sent Marceline and Marshall flying. When they landed they hissed in pain as fire had burned them slightly.

With the water one she tried to whip Finn and Fionna, but they having skills, dodged it.

"Fools you think you're so smart and skilled well guess again!" she laughed darkly.

"Yeah well at least we haven't got hit yet." mocked Fionna.

"I was just playing around I liked to see you try it's funny."She laughed again.

Then the whip she was holding disappeared and she flicked her left hand sending Finn and Fionna flying.

Just as they landed a giant Jake came in and knocked (y/n) to the side and scooped up everyone including poor (y/b/n)'s corpse.

Slow getting up (y/n) scoffed then whispered amateur before walking over to the Ice Kingdom.

With a click of her fingers she transformed into her normal form and flew up to the ice tower. She was going for Ice King and Queen.

She knocked on the door. After a few minutes of waiting Ice Queen answered the door.

"Oh hello darling what can I do for you?" she asked.

"I uh thought maybe we could hang out for a bit." she lied looking down and scuffed her foot against the ground, giving off a shy appearance.

"Yeah sure come in."She said a little too excitedly.

That was all Jake could hear for a few minutes . Then there was a loud scream and a bang which sent ice flying everywhere.

The ice was so sharp that Jake had to make a run for it.

Jake could hear the high pitched scream from the ice royalties and the evil laughter from (y/n) as she tortured them.

Scared for his and everyone's lives Jake ran to the Candy Kingdom.

Princess Bubblegum and Prince Gumball were evacuating the citizens into the great hall telling them that there was going to be a dance party plus sleep over. They only lie to them because when candy people get scared they tend to explode.

"Jake what is going on?" PB asked after all the citizens where in the hall.

"It's (y/n)." replied Jake with a sad voice.

"(y/n), how?" asked PG.

"The Lich I guess because when I arrived to get everyone he was sitting on a tree laughing his head off while (y/n) knocked around Finn and Fionna. This is all my fault if only I didn't get so angry with her maybe she wouldn't have left.

"No," said Finn weirdly as he was just waking up. "He would've come for her anyway."

"Alright let's get you guys inside, but come this way so no one can see you like this." PB said leading them to a secret passage which went to her room.

She instructed Jake to lay Finn, Fionna and Cake onto her bed. Flame Prince and Princess was to be sent over to the corner so they don't burn down the room.

PB and PG ran around fixing everyone up and brought in some soup before leaving with Peppermint Butler to calm the citizens who could hear the fighting outside.

"It's alright everyone it's just the speakers, we're having a little issue never mind that go set up your beds we should be done soon.

After the speakers were sorted and a dance mix was at full blast did the Prince and Princess retire back to the room of sleeping people.
