A portal opened before TME stepped out with Atomsk exiting a moment later before he looked around with a raised eyebrow.

"This the right place?, I may have taken a wrong turn at albuquerque." TME said with a joking tone.

Atomsk rolled his eyes before looking at the readers.

"Hey everyone, Atomsk here and welcome to my new story called "Adventure Time: DMC Style." If any of you get confused, it's a Devil May Cry crossover. I want to thank my good friend TME for joining me and also being part of this project. Go a head man and take a bow." Atomsk said when he passed the spotlight to TME.

TME did bow before he spoke up.

"Thank you, and in case anyone is confused, were taking certain characters and using them for the story, for example, Atomsk has Finn and Jake for this chapter while I control the character that will pop up later, I'll leave it as a surprise though." TME said before he looked to Atomsk.

"Any complaints so far?" TME asked before he sent the spotlight back to Atomsk.

"No complaints here." Atomsk said before turning to the readers.

"Now before reading this, I want to also thank another author name CorvoKuro, whom inspired and encouraged me to write this. I hope you all enjoy." Atomsk said before the camera fades to black before it fades into the Citidel area where the story begins.

This story takes place near the end of the Citadel (but with a different twist)… with Finn lying on the ground from what just happened after Martin escapes.

Finn, with the loss of his bear hat and shirt, lies on the ground while holding the stub of his right arm where his grass sword transformed when it tried to help… but was ripped off in the end.

Jake was holding his ground against the Lich till it knocked him out.

Then it has its eyes on Finn.

The young human sees the Lich approaching him.

He used whatever strength he had to crawl away from it till he had his back pressed to one of the broken prison columns.

Unable to do anything, Finn starts to lose consciousness.

Before blacking out, he hears the Lich speaking.

"Weak and pathetic, like your entire race... No matter how many times you beat me, I always come back."

Jake in the meantime was finally able to regain consciousness to see the Lich near his brother.

"Farewell, Finn the Human." The Lich said before it brought its hand up to strike him.

Then suddenly…

"Noooooo!" Jake yelled as he stretched his body to the Lich and wrapped around its face.

The Lich struggled as it tried to get rid of Jake.

"Get off of me you insolent mutt!"

Finn was seeing this but was still too weak to move.

"J-Jake." He said before blacking out.

It didn't take too long till Finn opened his eyes. He finds himself in a dark void.

"Am I dead?" He asked hoping he wasn't dead.

That's when he heard a random and yet familiar voice.

"Not yet… but if that bag of bones gets past Jake then we will be."

Finn didn't know who said that.

"Who's there?" He asked while looking around a bit.

The mysterious voice chuckled before a tap was felt on Finn shoulder.

"Try looking behind you..."

Finn turns around to see...himself?

The young human was so shocked as he looked at this other Finn.

The imitation looks like the original, but with some minor differences.

He wears the same outfit as Finn, minus the bear hat.

Instead of blonde, the other's hair is white (Like Dante, Virgil and Nero's)

The imitation's right arm is like Nero's from DMC 4.

"W-Who are you?" Finn asked while still feeling shocked.

The imitation Finn smiles before answering with a shrug.

"Should be obvious… I'm you… or a different side of you."

Finn's eyes widen when he heard that.

"Say what!?" He screamed.

The imitation Finn chuckled at his reaction.

"Like I said… I'm a different side of you… you're Demonic side."

Finn was so confused by his statement.

"But how's that possible? All my life I've been known as the "last human"."

"Ehh, you'll hear more later, but to be exact… your a half demon like that vampire queen." The imitation said while it took a moment to let the info sink in.

Finn was at a loss of words. There were so many questions he wanted to ask.

The imitation Finn sensed this which caused a slight grin before it got a serious look.

"As much as I want to answer things… we got a serious issue right now." The imitation said before it waved his hand around in a circular motion, thus creating a special window in Finn's mind.

Finn looked at the 'window' to see Jake still wrapped around the Lich's face while he held the Lich back.

It left scratch marks on the dog's body making Jake yell in pain.

"Jake!" Finn screamed as he was worried for his brother.

The imitation Finn sighs before giving him a half lidded look.

"You do remember were in you head right?" the imitation said before looking to the screen.

Finn continues seeing his brother in pain while holding his ground.

"What can I do?" He asked.

"Shouldn't that be obvious?"The imitation asked.

Finn looks at him with an unsure look which caused the imitation to sigh.

"You fight that's what!" The imitation Finn said with a serious look.

Finn looks down and says something he never hear himself say.

"I-I can't."

The imitation's face didn't change except for a raised eyebrow.

"I'm sorry... but what did you say?" He questioned.

Finn looks at the imitation.

"Look at me. I lost my arm. I don't even have a sword. How am I supposed to fight with one arm?"

"Don't kid me… what do you think Billy would do?" The imitation asked.

"Who am I kidding? I'm not Billy." Finn interjected.

That's when the imitation got serious again.

"You're right, You're not... You're Finn the greatest hero of Ooo. You took down larger monsters and the Lich more times then some could count. So giving up isn't an option!" the imitation said.

"I-I don't want to give up. But I don't know what else I can do." Finn said.

"There is one way..." The imitation said.

Finn looked at him.

"What is it?" He asked which caused the imitation to look him in the eye

"That parts easy… just awaken to your demonic power." The imitation said with a grin on his face.

"B-But what if I can't?" Finn asked with doubt in his voice.

"Oh… then will you be fine with this walking pile of bones getting out… Harming everything innocent… and the people you care for?, like Jake?, PB?, Lady?,... Marceline… and FP?, I could go on but you get my point right?" the imitation said while crossing his arms.

Finn did take a moment to think. That's when he heard Jake screamed in pain as the Lich finally got him off.

"So… Want me to lend a hand?... So to speak..." the imitation cryptically said with a serious look.

Seeing Jake in pain made Finn get serious. He did not want the Lich killing anyone. He looks at the imitation with new determination.

"Let's do it."

The Imitation grins before holding out the demonic looking hand for a hand shake of sort.

"Well then, take my hand and I'll do the rest." The Imitation said with fangs showing from the grin.

Finn gets up and grips the imitation's demonic hand before the scene switched to Jake and the Lich.

Said dog lies on the ground while the Lich approached.

"I'm going to make your death quick and painful." It said as it was about to strike before it felt a strange disturbance.

When the Lich looked back… it was shocked when Finn was slowly standing up… and to further shock of the Lich and Jake … Finn's hair was turning white… before he fully got to his feet and the hair hid Finn's eyes… and only a grin was seen.

"Impossible." The Lich said with a shocked look.

"F-Finn?" Jake questioned as he couldn't believe what's happening.

Finn then grinned before he spoke up… but with a slight echo to the duo's shock.

"Not quite bro… you see, I'm giving Finn a bit of a break while I take care of this bag of bones once and for all." Finn? Said when he opened one eye which looked to the Lich… which glowed with a blood red light instead of Finn's normal looking eye.

That comment upset the Lich greatly.

"I don't know what you are...but it matters not as I will end your pitiful life...human." The Lich said as it ran to strike Finn.

Finn? Grinned when the Lich got close before the Lich's hit connects with his chest which sent Finn? flying and crashing into the gem like wall with a noticeable crater forming in the rock before a dust cloud formed as a result.

"FINN!" Jake screamed.

The Lich grinned at his handy work.

However chuckling was heard to their shock before they hear Finn? Speaking up in the cloud.

"I wouldn't celebrate if I were you… I would look to the arm that you hit me with… if it's still there that is..." Finn? Said through the cloud.

The Lich was confused till it looked down and was shocked at what it saw.

The Lich's arm, the one that he hit with… was missing from the forearm to hand which only showed a broken arm in its place while the cloud cleared more which showed Finn? Who held the Lich's severed limb with his left hand.

"I believe this belongs to you." Finn? Called out with a grin before tossing the arm back before it lands in front of the Lich.

Jake was shocked that Finn did that. Just who is he?

"No human can ever do this." The Lich said as it looked at Finn.

Finn in turn grins before holding the right part of his arm that was still there out.

"Your right… no normal human could, but we're a half Demon." Finn? Said before a red flame appeared from the stump before it pulls away to reveal a demonic looking arm that had a red glow before he held it out.

"Though newly awakened would be the right word...and I should thank you… I mean, I was asleep for who knows how long and you nearly killing my human side woke me up." Finn? Said before he clinched the demonic arm to test it out.

Jake gasped at the new arm on Finn.

The Lich was now feeling a little...fear? It didn't know why but knew there was more to whatever Finn is.

Finn? Grinned when he punched the arm a few times before looking to the Lich.

"Oh… is that fear I sense?" Finn? teased when he turned a bit to face the Lich.

"I don't feel fear...I bring it." The Lich said as it tries to attack Finn again.

This time when the Lich got close… Finn? Ducked under the arm and got ready to hit the Lich with the Demonic arm.

"I wonder… if my human arm ripped your arm off… what would my demon arm do with a full power punch?" Finn? Asked the Lich with a grin on his face while his eyes glowed blood red when he sent the attack at the Lich's stomach while time seemed to slow.

The Lich's eye widen when it felt that feeling again… the feeling of fear.

Jake stared at AWE at what was happening.

A moment later… the attack connects… but instead of sending the Lich flying… Finn?'s demonic arm went clean through the Lich's gut before he gripped the Lich's spine when he purposely missed it.

"Now then… why don't I end this." Finn? Said with a wide grin before his arm glowed with a red light when it starts to absorb the Lich's power into itself.

"Ahhhhh!" The Lich screamed as it felt its power and life force being drained.

Finn? grinned more before he spoke up.

"I'll give you a parting gift Lich… I'm a descendant of Sparda, that knowledge was etched into my or our genes." Finn? Said before the draining sped up which caused the Lich's body to crack here and there.

The Lich's eyes widen when it heard that before the light in its eyes fades to black. Once that was done, Finn? Pulled his demonic hand back with the spine in his grip before the body of the Lich collapsed to a pile of bones.

The demonic arm then glows green with the lich's power before the spine seemed to shift with a green light before in its place was a dangerous looking bone scythe.

Finn? Then tossed it into the air for a second before catching it with his human hand and starts to spin it around to test it with a grin.

"Not bad, I'll have to tell Finn how to access this later." Finn said before he starts to spin it faster and actually making a few complex combos which left a green mist of sorts in its wake before he rests it on his shoulder.

He then looked to Jake with a grin.

"What do you think?, badass or what?" Finn? Asked when he starts to approach Jake after he made the scythe vanish into his arm which allowed it to return to the normal red glowing arm.

Jake was still staring at AWE at what happen. But it didn't stop him thinking how cool it was.

Finn? Grinned at the look Jake was giving him before he cleared his throat.

"As interesting as I am, I'm sure you got a question or two right?" Finn? Asked with a raised eyebrow on his grinning face.

Jake finally got back to reality as he looked at Finn?

"Uh, yeah. 1) How'd you did that? And 2) Who are you?" Jake asked while hoping if that still is Finn.

"Hard questions to answer… 1.) instinct I guess when I absorbed that pile of bones and turned him into my weapon. 2.) as for who I am… I got no name, I just woke up remember?" Finn? Said with two fingers up.

Jake gulped before asking.

"Is Finn still there?"

Finn? Took a thinking pose of sorts before he answered.

"Yeah he is, though he got knocked out from the sudden switch so he can't appear to talk and since I'm running out of time fast, I'll need to explain things quick before I hand control back to the passed out Finn, but don't worry, he's alive and well since I am… though you'll have to carry him out since… we'll be knocked out right?" Finn? Said with a grin.

Jake nodded in agreement.

"Alright, first off I'm a bit unique in that I am the demon side of Finn, but because of certain things like him not getting the right training, I was dormant until now and since Finn already has his own identity, I exist as a separate being, you following so far bro?" Finn? Said with a serious expression.

Jake nodded as he understood. But deep down he was shocked to find out about the first part.

"Okay, now the second part, this arm is called a Devil bringer, I'll have to explain more later about it's combat abilities, but if the conditions are right then I can absorb certain energies to get abilities or weapons like I did with the Lich just now." Finn? Said while showing the demonic arm up close, it was all red but the glowing helped give it a noticeable pattern.

Jake was surprised when he saw the arm. He couldn't believe this is what killed the Lich.

"Honestly the rest is more or less instinct to me so unless you can find someone who knows more about Sparda then were out of luck." Finn? Said before his arm glows to his surprise which made him look to see something that Jake didn't when.

"Hooo… Seems that grass sword curse doesn't want to share and is trying to reject me." Finn? Said when he examined the part of his arm which connects to the former stump.

"What are you gonna do?" Jake asked.

Finn? Just smirks before he gripped his Demonic arm with his human arm.

"What do ya think!, I'll absorb it!" Finn? Said with a grin before his arm pulsed when a green energy starts to flow into the arm, it was a lighter shade than the Lich energy he absorbed.

Jake stared at amazement as he saw this.

But it seemed that the curse was stubborn so it made it tough for the arm to absorb it until… the Arm glows a bright green and dims to a lighter shade before to Jake's surprise, the grass sword appeared from a small ball of energy which Finn? Caught with the demonic hand it appeared from.

"Hehe, gonna need to try harder than that to get rid of me." Finn? Said before he turned away from Jake to test the grass blade out on a nearby gem rock which got turned into multiple cubes a moment later… something that Finn would have trouble doing normally.

"Whoa!" Jake exclaimed after seeing that.

Finn? Then stumbles which was surprising before looking to Jake after he made the sword vanish back into the demonic arm which returned to the normal red glow.

"Seems I'm out of time bro…. I'll… leave.. The re..st to…" Finn? Tried to say before the arm's glow dimmed greatly before he starts to fall.

"FINN!" Jake yelled as he caught him.

He checked to see if he was okay.

To his surprise, aside from the new demonic arm and the silver hair, he looked unharmed even after taking a punch from the Lich, either he was more durable now or he could regenerate somewhat from small wounds.

"Don't worry bro. I'm gonna get you out." Jake said as he looked at the random portals.

He found one that was close to him and stretched his body towards it. Once he was inside, his head popped out to see so he can keep an eye on Finn's body as he brought him up.

Little did they know, they're about to be seen from someone that they know.

The camera fades back in to show Atomsk and TME who watched what was going on the Citadel before TME noticed the readers.

He nudged Atomsk with his elbow before he points to the readers who appeared.

"Welcome back everyone. Hope y'all enjoyed the first chapter. Boy is the new Finn a badass. Wouldn't you agree TME?" Atomsk asked as he passed the spotlight to TME who grins.

"Well… more like Finn's demon half, he's a separate but same guy remember, don't worry though, Finn will have some fun with his new abilities to come without his Demon halfs help." TME said when the ideas just kept coming.

Atomsk was having ideas too for the next chapter.

"Well everyone hate to cut this short but TME and I need to work on the next chapter for "Dimensional Drifters School." If any of you have never heard of it, I highly recommend that you read it." Atomsk said as he passed the spotlight to TME.

"And the Lemon version is on my account on AO3 if some of you are curious about certain things that don't quite make sense while the non lemon version is on FFN, there are also other stories you can enjoy if your curious." TME said before speaking up again.

"My full name or author name is Twilight Master Emerald if some of you are confused." TME said before looking to Atomsk.

"Any last words before we end the chapter for now?" TME said when the spotlight goes back to Atomsk.

"Ah yeah...Now in my story, there will be lemon scenes in the future. But it will end up in AO3. If you of you go there, my author name in AO3 is godofwar058. Anyway goodnight and have a pleasant tomorrow." Atomsk said before the camera fades to black.
