Cry of adventure time Chapter 3: The Terror in the Cellar: Part 1, an Adventure Time with Finn and Jake + Cry of Fear Crossover fanfic

A portal opens near the candy kingdom before TME appears in it, he looks around for any Banana guard before stepping out which caused the portal to close with a bang.

TME hid in the bushes for a moment as a result of the sound before he looks around again for anyone, when he didn't see anyone he looked to the readers with his head popping out of the bush before giving them a shushing gesture.

"Yeah... I know I'm in a bush like a coward but I don't want to cause trouble with the Banana guards." TME said when he looks around again for any banana guards before looking into the infirmary to see the shocked group which made TME look to the readers again after a moment.

"Last time, Finn had to go through an apartment complex after he *woke up* in a strange place, and after fighting many horrors and after his fight with the nightmarish version of Princess bubblegum... he passed out and *woke up* some time later to find himself in a different area with Simon Petrikov of all people... Or is he Simon?" TME said with a smirk while he air quoted the wake up parts.

"So what does this mean for Finn now that he met Ice kings form before he went insane, is this Simon a good guy or is he wolf in sheep's clothing?, lets find out shall we?" TME said before the camera panned into the infirmary with the shocked occupants.

Reality/ candy kingdom/ infirmary/ Reality/ Candy kingdom/ infirmary/ Finn (Coma), Ice King (Unknown), Jake (Injured but healing) Lady, Princess bubblegum, Marceline, Peppermint butler, Pillowmint butler, Nightmare princess, Huntress wizard

Everyone who knew who the man was could barely believe it... the others were looking with confused looks on their faces before Marceline spoke up in a slight whisper.

"Simon?" Marceline whispered while she approached the images a bit to get a closer look before the camera went to Finn and Simon when the others didn't say anything else when Simon spoke up.

?/?/ Finn, Simon

Finn only stood there in shock while Simon chuckles for a moment.

"So... surprised?" Simon asked which got Finn out of his shocked state before he finally spoke up.

"Y-You...You're..!" Finn said while pointing to Simon which caused Simon to chuckle again at Finn's reaction.

"Not the Ice king here I can tell you that much." Simon said which made Finn shake his head for a moment.

"H-How!?" Finn said when he placed his arms at his side before Simon points to Finn's head, his forehead to be exact.

"You can think and blame that gem fragment in your head for what's happening for some of the issues here." Simon said while Finn touched the gem piece in his head for a moment with some confusion.

"Uhhh..." Finn groaned out when he was more confused then ever which made Simon grin a bit before he gave Finn a serious look.

"I'll explain this part then, we don't have much time to rest here." Simon said which confused Finn more which made him speak up.

"Uhh... why do we not have enough time?" Finn asked which caused Simon to clear his throat.

"Another time perhaps, but for now... the jewel..." Simon said before he continues before Finn could say anything.

"I'll ask a few questions to see if you can follow alright?, It'll also help me with explaining things." Simon said which caused Finn to get more confused... but he nods anyway since this might answers some questions that float in Finn's head.

"Very well... do you remember that the crown is the reason that I became the ice king?" Simon asked which made Finn nod.

"Yeah... though why ask that?... wait... I'M NOT GONNA TURN INTO SOME KIND OF ICE PRINCE AM I!?" Finn said before panicking at that last bit while Simon sighs before he snapped his fingers to get his attention.

"Fortunately that isn't the case, but that gem fragment plus your memories and mine are the cause of all of this... you see the gem fragment in your head acts as a bridge of sorts between your body and mine, aside from everything else here... you and I are the only real people here." Simon explained which made Finn's eyes go bugged eyed before he shook his head.

"H-Hold on!, you're saying that this is all fake?, what about the pain I felt earlier!?" Finn said which made Simon sigh again.

"I'll keep it simple when I say this, and it was tested with a high degree of accuracy by other humans in the past so this info is the real deal, but if you take a big enough of a shock in here and you believe it's real with 100% of your being, then it can effect your body in reality perfectly which could mean your death." Simon said while Finn stood there in shock.

Simon cleared his throat which got Finn's attention again before he spoke up.

"So... any questions about this place before we leave?, though try and keep the questions simple please, like I said... we are short on time here." Simon said while Finn reached for his backpack a moment later to pull out the gun, the ammo clips, and the syringes.

"Y-Yeah... I found these in that previous place... what are they exactly?" Finn asked while Simon took one of each item to examine them.

"Hmmm... Well... I'll start with these first." Simon said when he held the gun and Ammo after he placed the syringes on a box nearby.

"This is a gun... a pistol to be exact with these being the ammunition for it... I think it looks similar to a desert eagle that I saw once in the past... It's a ranged weapon that most humans used for long ranged attacks, it's not the best weapon of the past, but among pistols... one of the better ones." Simon said about the gun and the ammo cartridges before placing the ammo in various pockets in his jacket and clothes before he fiddled with it for a moment to reveal that he removed the ammo already in the gun to see that it was still full before he placed it back in with Finn watching while he showed the syringe.

"This is morphine, a pain numbing substance, however in here... it seems more like a healing item you would find in a game." Simon said which made Finn grin.

"So that stuff is good for injuries here?" Finn asked while Simon frowned.

"In small doses yes, take to many however take to many... and you can experience some nasty side effects." Simon said while he held out the Morphine to Finn.

"So try to not get badly hurt again like you did earlier when I checked you for injuries, it seems like something exploded point blank or something, but if you do, just use one and try not to use another for an hour at least." Simon warned while Finn gulped at the info and sweatdropped when he remembered that exploding creature before he took the syringes back and placed them in his backpack.

"So... what now?, I don't know what to do next." Finn said while Simon took a moment to think.

"For now we should split up and search this place for a way out." Simon said while he walked to one of the doors which surprised Finn.

"H-Hold on!, what if you run into any creatures here?" Finn said while Simon held the pistol in his right hand when he walked over to a door.

"I'll be holding onto this for now since I know how this works, and don't worry... I was able to survive here longer then you have since I have experience dealing with stuff like this on a daily basis." Simon said with a grin on his face before he entered the door and closed it before Finn could say anything else. (Simon entered the door where the doc enters and I'll be coming up with my own stuff for Simon's area and I'll switch between the two.)

Finn just stood there in shock at Simon's actions before he shook his head for a moment to get rid of it.

"Okay?... I guess I'll be going in another direction then." Finn said before he looks around the room to see that there is the door that Simon entered, another nearby and one that most likely led back to the apartment.

"Not heading back there again." Finn thought before he looks to Simon's door with some worry before he shakes his head.

"Ehh... the guys right, he's probably better at this mind stuff then I am." Finn thought before he walks to the other door and enters while the camera went to reality.

Everyone watched the talk between Finn and Simon before they split up which showed that the camera was still centered on Finn which made Marceline look to Nightmare.

"H-Hey Nightmare... can we watch Simon as well?" Marceline asked which caused Nightmare to sigh before she snaps her fingers which caused the screen to split in half before a secondary image appeared, one that showed Simon entering a room that looked like it was flooded... But Nightmare thought something was...off about Simon.

"Hey... is this guy real or just a trick to fool Finn." Nightmare said which caused Marceline to look to her with a raised eyebrow.

"Where are you going with this?" Marceline asked in a serious tone which caused Nightmare to sigh.

"That place seems to be made to try and mess with Finn in horrible ways so a possible ally turned traitor wouldn't be much of a stretch here, how do we really know if this guy is the real deal or not?, I never met this Simon guy but you have from the way you reacted... but I'm just getting a funny feeling that he shouldn't be trusted." Nightmare said which caused Marceline to chuckle a bit which confused Nightmare a bit.

"Says the person who used to cause trouble in her own kingdom before taking over, didn't you try to get rid of Finn and Jake in the past before becoming really friendly with Finn." Marceline said which caused Nightmare to get irritated with the Vampire queen.

"What!?" Nightmare growled with anger showing on her face when green mist like energy emitted from her body.

"Did I stutter." Mareceline growled with glowing red eyes out which caused the others in the room to quickly worry that a fight would break out before a familiar voice spoke up nearby which got everyone's attention.

"Hello?, is this the right room?" ? called out which revealed a worried Flame princess, or Phobe, to everyone's surprise.

"What is she doing here?" Nightmare said in an angered tone with crossed arms, she remembered how Flame dumped Finn over one mistake while Flame got a little irritated at Nightmare for a few reasons, mainly the fact that she was a stranger to her.

"Excuse me?, I'm the Princess of the Flame kingdom, or the new flame king after I took the throne from my father!" Flame said which made Nightmare sigh which seemed to irritate Flame more.

"Like I don't know that, what I mean is why are you here exactly?, wasn't this suppose to be secret or something to prevent people from worrying?" Nightmare said which caused Phobe to raise an eyebrow.

"You do realize that rumors spread fast... even if Bubblegum did try to hide what happened, someone would speak and it got to my kingdom a day ago... I left Cinnamon bun in charge and rushed on over." Phoebe said which caused Nightmare to grin a bit.

"So how can you help?, burn him or something?" Nightmare asked which caused Phoebe to blink a few times while she process Nightmare's words before her body flared with anger.

"What..." Phoebe growled with rising anger which caused Marceline to frown with narrowed eyes while she held her axe guitar in one hand before Bubblegum cleared her throat to get everyone's attention before a fight broke out.

"Listen, we have more pressing matters to attend to, like seeing if the Simon on the screen is the real deal or a fake like Nightmare said." Bubblegum said which caused Marceline grit her teeth before she looks to Nightmare.

Huntress walked over to the trio which got the their attention.

"She has a point, there is also the issue with Finn as well." Huntress said while crossing her arms while Phoebe gave Huntress a slightly confused look.

"Who are you?" Pheobe asked which caused Huntress to look to Phoebe.

"Huntress Wizard." Huntress simply said which caused her to get more confused.

"Ooookay... why are you here?" Phoebe asked which made Huntress shrug her shoulders.

"I heard about what happened to Finn after I ran into Nightmare Princess, and since I owe Finn... I thought I could help with my magic." Huntress said with with a barely noticeable smile which caused Nightmare and Phoebe to give Huntress slightly confused looks when an odd feeling was felt in their chests, or for Phoebe's elemental matrix but they kept quiet at that when Marceline spoke up.

"So... You can control dreams right?, can you send a person in?... like me to prove that the Simon in there is real or not?" Marceline said seriously to Nightmare which caused everyone to look to her with various levels of surprise.

"What the Bjrok!?, are you insane Marceline!?" Bubblegum said while Marceline raised and eyebrow to her.

"You got a better Idea Bonnibel?" Marceline said which made Bubblegum blink once before Nightmare cleared her throat to get their attention.

"If anyone is interested in what I have to say... I can do that but I used what energy I got back to split screen those two, so it'll be awhile before I can do something like that." Nightmare said which caused everyone to look to one another before Nightmare looked to the two screens.

"Besides... We got to watch what happens for now anyway, they're in two areas now." Nightmare said before everyone looked to the two screens.

?/Finn's area/ Finn

When Finn entered his area, he was immediately attacked by a creature who was rushing him in a reverse crab walk of sorts with it's head hanging to the ground which caused Finn to get ready to counter while the creatures law opened in a roar as it approched.

"Guh!" Finn grunts when he jumped into the air and the creature crashed into the door, he then waits for the creature to get up to show it's mangled head before he stabbed forward with the knife and stabs it in the side of it's head which caused it to twitch for a moment before it fell to the ground... dead.

Finn's relief was short lived when he resumed when he walked down the hall some more when another creature appeared which charged him when it spotted Finn.

Finn in return charged the creature and hopped on top of it when caused it to crash to the ground, Finn then stabs the knife deep into the creatures skull which caused it to twitch like the last one before it laid still to show that it was dead.

Finn sighed in relief when he noticed that nothing else was coming at him for a moment which allows him to catch his breath while the sense went to Simon's area.

?/ Simon's area/ Simon?

When Simon enters the area, he found it to be a simple square shaped room with two exits in front of him... and it seemed the room was flooded to ankle high which was slightly confusing to him.

There was also a cross of sorts which seemed perfect for pinning a human to it.

"Interesting..." Simon thought while he walks over to the door near the cross like object to test it and saw that it was locked.

"Hmm... Simon hummed before he turned to the other door to see if it was locked as well.

When he turned he got a bit surprised to see a human like figure in the middle of the room which made Simon pull out the gun he got from Finn.

"So... are you gonna attack me?" Simon said to get the creature's attention which made it look to Simon with a disturbing grin on it's eyeless face which made Simon fall silent.

"Let's see if this creature uses sound for finding prey." Simon thought while he carefully pulled out one of the ammo clips and tossed it near the creature.

The effect was instant... the creature lunged for the ammo clip with clawed hands which made it bounce farther away which made it gave chase while Simon took his time with aiming the gun at the creature's head when it stopped for a moment when the Ammo clip stopped bouncing.

Simon fired the gun which hit it's mark before the creature fell to the side and onto the ground... dead still, apparently head shots work here with deadly results.

But Simon wasn't taking the chance, he approched the body before firing a couple more rounds into the creature's skull which caused some blood to hit his lab coat as a result.

Simon sighs in relief after he looked around the room again for more creatures and found none which allowed him to go over to the unchecked door in the room while the camera went back to Finn.

?/ Finn's area/ Finn

In the meantime that Simon was dealing with the creature, Finn entered a few more rooms in the hallway.

one was a dead end with a ammo clip, another had a door leading to another area, and one had a slightly faster variant of the crab walker creature which nearly got Finn from it's surprising speed.

Finn had to jump to avoid it and when it turned back around to charge Finn again, Finn kicked the top of it's head like a soccer ball which sent the creature flying somewhat to stand on it's feet.

It then started to fall back to the ground before Finn spun the knife into a reverse grip which allowed him to stab it in the back of the head which caused the creature to go limp before Finn let it fall to the ground after he pulled his knife free.

Finn took a moment to look around while catching his breath... he only found a syringe which made him exit the room a moment later and towards the room with the door to another area while the camera went back to Simon, though the images seemed... distorted greatly which confused the watchers.

?/ Simon's area/ Simon?

Simon in the meantime went to the unchecked door before he tried to open it.

However... when he did, he felt something... Boney... gripped his shoulder with extreme force which made him wince before he looked over in shock before the last thing he saw was two glowing green eyes with a eerily familiar voice.

"Let's give Finn a scare shall we?" The person said before Simon's vision grew darker as the person placed the gas mask back on Simon's face with an echoing chuckle while the scene went to reality when the images blurred to static.

Everyone saw that Finn's screen looked normal, but when they saw Simon's screen acting odd, Marceline looked to Nightmare with worry.

"H-Hey, what's going on with Simon's screen!?" Marceline said with some panic in her tone while Nightmare looked to the screen with a thoughtful look before she looks to Finn and the ice king.

"Honestly...I don't know much right now, but as far a I can tell, it seems things are worse then I thought when I felt some grade A evil magic for a moment... but it was... emitting from Finn's body for some reason." Nightmare said in a worried tone when she took a moment to look to Finn which caused everyone to look to Nightmare like she had two extra heads.

"WHAT!?" Jake shouted while he rolled in front of Nightmare before continuing.

"You're telling me that some very bad magic is somehow coming from the most heroic guy in all of Ooo!?, isn't that a bit of a stretch?, I mean what the flip NP!" Jake said while Nightmare pinched the bridge of her nose in annoyance at Jake's questions.

"I don't know what the cause is... but I can tell it came from Finn at least before the connection got cut on Simon's end." Nightmare said with a slightly worried tone when she looked back to the screen when she saw Finn exiting the building and into a rainy alley while everyone else did the same with various levels of worry.

?/ Finn's area/ Finn

When Finn exits the room he was in... he found himself in a alleyway with rain pouring on him and stairs next to him to take him to ground level.

He walks up the stairs with the knife held at the ready before he looks around after making sure the coast was clear.

After a moment of looking around, he found a Nightstick that some Candy kingdom police use which allowed Finn to pocket the knife for a moment to test the nightstick out.

Apparently it felt right in multiple ways, it could work as a fake sword, he could use it by gripping the shorter stick part to go into a hand to hand stance of sorts, and he could pull out the knife for duel wielding or the phone for navigation.

Finn took a minute more to get a feel for the nightstick before he continues onward while he held the knife in his left hand since the path for now seemed simple enough so that Finn wouldn't get lost.

However... when he got further in, he was ambushed by 4 crabwalking creatures which really surprised Finn and the others watching while he got into a guarded stance after dodging one of them clawing at him.

Finn jumped back again when another tried to attack his legs again, but Finn was ready this time which allowed him to jump over the creatures attack and give it a strong kick to the top of it's head which sent it flying onto it's front with a noticeable dent on the back of it's head.

Fin repeats the process again with the one that swiped at him the first time except this time he stomps it's jaw which gave a sickening crunch as Finn caved it's head in which made him shudder when he saw red blood flowing from the body.

However his issue had to wait when the two remaining creatures tried to get him in a pincer attack which forced Finn to hold the nightstick in his right hand and the knife in his left in a duel wielding guarded stance.

When they got near him, Finn stabbed the nightstick towards one that had it's mouth open for another roar which caused Finn to jam it into it's mouth while Finn spun his knife into a reverse grip before using it to jab the other creature in the side of it's head which killed it before Finn roared when he spun around which got the last living creature to fly away when it slid off of the nightstick.

However it only skids on it's hands and feet before taking a moment to recover before it charged Finn with a roar which showed it's now messed up teeth.

Finn grit his own teeth while he braced his body and when the creature got near, he surprised everyone by dropping his weapons and slamming his hands onto the creature's shoulders which caused its head to go upward.

Finn then grips the creature's shoulder's tightly before actually lifting the creature over his head and slamming it onto the ground behind him with a sickening crunch and after a moment... Finn saw that all four were dead which made him sigh in relief before he picks up his weapons.

After checking his body for injuries, he found that he wasn't damaged before he continues onward... which lead to a dead end of sorts with a door leading down into a building's basement and an alleyway leading nowhere with trash on the ground and a magazine near a puddle.

Finn approached the door since it was the only way to continue and found that it was locked with a keypad which made him sigh from annoyance, when he walked back up he decided to check the alleyway across from him to see if he missed something.

When he did, he took a look at the magazine since it looked like the most obvious thing to see right now and saw a phone number clearly... 543-214.

Finn pulls out the phone he got from Simon and typed the number in... when he hit the OK button, it rang for a moment before someone on the other end picked up, however the only thing Finn could hear was breathing.

"Hello?... Hello?, Who is this?" Finn asked the person for a moment before a raspy voice was heard.

"Follow the path of inequity, Yeild not to the light, darkness is your new master." ? said which made Finn raise an eyebrow in shock.

"What!?" Finn said before the person continues.

"The number... remember the number, and you shall proceed." ? said which made Finn narrow his eyes.

"What the flip are you talking about!?" Finn said before the person spoke up again.

"5...2...4...7." ? said which irritated Finn further.

"Glob dang it!, Help me!" Finn said when the phone cut off.

"...great...now what?" Finn said before he turns to the door with a thoughtful look on his face.

"I wonder..." Finn said before he walks over to the door and enters the code on the keypad... and low and behold... the door was unlocked after a moment which made Finn grin.

"Nice!" Finn said with a grin on his face at his luck turning before he approaches the door and enters it before the scene fades to black.

The camera panned away from the dream screen to show TME hiding in the bush while he watched what was happening before he noticed the readers.

"Hi, and sorry this chapter was late, I think I got a procrastination problem or something and I've been trying to... limit the amounts of words I write per day, I'll try to be faster but I can't promise anything." TME said while he looks around the area before exiting the bush.

"Now before I leave, this is part one, part two deals with the actual boss, again sorry but I took to much time with this one and I thought this as a good stopping point." TME said while a portal opens near him.

"Now, please no flames, only constructive reviews please to help me be a better author on , now then... Adios!" TME said before he steps into the portal before it closed with a bang.
