~List of struggled Summaries~

(more summary inside) Zero is a supersoldier project, perfected for war and combat. It is the year 2030, World War III. During a special mission, a space-time vortex was created and Zero is sent a thousand years into the future, the land of Ooo. Little did he know that the world war came to 'The Great Mushroom War.' I suck at summaries and this is actually better than it sounds!

(more summary inside!) Supersoldier Zero is in for a surprise as he was thrown into a space-time vortex into the land of Ooo. As he tries to understand where he is, he is convicted to be a dangerous criminal and is hunted down. Rating will be M later and contains Gender-Bent Characters. And robots. And I suck at summaries. FF is tough with limited summary space. Give it a read! :D

(more summary inside!) It is the year 2030. An unknown reason sparked the flare of warfare for the people of Earth. Technology is at it's height, Zero being one of them. A supersoldier project. In a top-secret mission, Zero somehow is teleported into Ooo, more than a thousand years in the future. FF is tough since there is limited summary space. Better summary is in first chapter!

(more summary inside!) Zero is a supersoldier project, created in the year 2009. (Earth's history in first chapter!, read the summary) As Zero is thrown into a time-space vortex, Zero finds himself in Ooo, the aftermath of World War III. Unfortunately, he is condemned to be a criminal, but only one person knows his innocence. Princess Bubblegum. PLEASE READ THE DESCRIPTIVE SUMMARY!

[2/15/13] Author's Note: Hello there and welcome to this story! I'm currently working hard on this story and very happy you're here reading this! I would put my summary descriptive, but it's very tough to do with limited summary space.

A/N: Hey there everyone! This is a period before the Great Mushroom War. I started to do a Call of Duty crossover with it, but it didn't turn out well. Hopefully, you'll read my Author's Note to fully understand the world before.

[if you already read this chapter, scroll all the way down to know why I reedited it]

THE SUMMARY: (remember, it has Call of Duty storylines implanted, but it doesn't effect the story, just raises the plot more)

It is the year 2030. Humanity has risen to it's height with technology and unbelievable advances in technology.

After the Raul Menendez/Cordis Die conflict, another deadly cyberattack makes all nations tense up as they don't know who or where the threat is. (read on to find out!)

A mysterious silo of nuclear weapons launched unexpectedly, slapping nations across the face in fear. Battles and 'accidents' began to slowly infest the earth and nations readied for battle. It is kind of like the future Call of Duty: Black Ops 2. Since it is the future, there are technological advances than the original 'past' of Adventure Time. (In Adventure Time, tapes seems like the latest thing.)

Planet Earth is about to embrace the wars of wars. World War III known to the humans inhabiting Earth and 'The Great Mushroom War' known to the people of Ooo.

Now comes in Zero.

He is a super soldier trained for anything possible through genetics and as you can say: 'inhumane procedures' to make the perfect soldier. Made in a top-secret project named 'Project Z', Zero was born or 'created' near the year 2010. By being the elite of the elites, elite special soldiers have no idea he exists. Anyone who takes part of the project must leave their old lives to heighten their defenses of their dear country, the United States.

By being top-secret, he runs solo on the most dangerous operations and survives through hardened training ever since he was a baby. By this and combining a Special Soldier's intense training, he became the perfect weapon for special missions. The Ultimate Super Soldier.

But now the glass is filled to the rim and only time will tell when hell breaks loose. Finding intel about the Russians, Zero's mission is to neutralize a Russian base and destroy it with explosives. (Specifically C4.) However in this mission, a space-time curriculum was created and Zero is sent a thousand years into the future. My guess is that the land of Ooo is about the year 3000 or so. Now in a strange world, Zero sets off to find a way back home. He is thrown into the land of Ooo!

Rating will change later to M.

[more of his past is revealed later in the story!]

Since Zero is a super soldier, he can survive more bullets and explosions than a regular human. With heightened abilities, he's a tough foe to take down. With hardened training, he can run faster and longer, jump higher, stronger and many other abilities to help him in many situations.

Some Call of Duty perks Zero has the ability have: (since I was trying to do a 'Call of Duty' Crossover with 'Adventure Time')

Sleight of Hand: Faster reloading

Extreme Conditioning: Longer sprint time

Blind Eye/Cold-Blooded: Tough to be detected my air support and sentry guns

Assassin: Cannot be seen easily by infantry, thermal, and radars

Blast Shield: Less damage by explosives

Ninja: Very little sounds made such has footsteps and knifing

Sitrep: Detection of equipment

Danger Close: More explosive damage

Commando: Longer melee range

Scavenger: Extra ammunition (in the story, he finds junk and turns it into ammo)

Toughness: Less flinch when hit

Some Halo elements:

Cloak: Short time of invisibility (he can already sprint and dive)

Yep, you read it, he has it. He also can generate any weapon he wants by a gadget from his hip. You'll see soon enough! Yes, just an idea from my head.

Deep in the mission he is in, he is sent into the world of 'Adventure Time'!

Thank you for checking this story out and read on! ^_^

I know that the AC-130 gunship isn't much used for transportation, but I love it. A sick awesome bringer of death. :D

Outskirts of Russia

"Remember, don't go loud. We need you to infiltrate the base and plant explosive charges in the heart of the base. Copy, soldier?" Command said to a soldier in black. Command had a rough face with scars and blemishes. His body covered in full gear, ready for battle.

"Yes sir, I understand." the soldier in black said back. The soldier in black was Zero, a special soldier, trained for anything coming his way. In a full helmet with a black visor and black gear, he looked truly to be a special forces officer. Along with black combat boots and black ski mask to cover his mouth, no skin showing what so ever.

"Good. Remember, you are the elite of the elite, trained for this and no one can do it but you. We've also managed to stalled enemy anti-air for just a few minutes." Command said. "If shit goes down in there, go loud and give it all you got. Command continued, pointing at Zero's hip. "Use it in the time of need. And do it well soldier." he finally said.

"Yes sir." Zero replied back.

"Command, we are now nearing the DZ." the pilot said as the gargantuan ship neared the coast Russia.

"Copy." Command said back, understanding that they were nearing the drop zone.

"Alright Z, we'll have to cut radio communications so the Russians don't know what we're up to. We'll have an RQ-170 drone up in the air, we'll be watching you. Command said to Z, his eyes in a commanding look. "We'll be there in time to pick you up. Go now Z, you're on your own. And good luck."

"Hoo-ha!" the pilot said loudly.

Zero then leapt out of the plane, into the darkness of the night.

As he was rushing down in the black sky in free fall, faint lights of the Russian base ahead him caught his eyes. Ascending down, the roar of the gunship disappeared and he pulled his parachute with his black gloved hands, landing in the coast of Russia. Snow surrounding the vegetation of the land. Zero got up and looked around his surroundings. With the wind whistling, bouncing off his black helmet he stood up and saw lights flickering in the distance. He dragged the parachute out of sight crouched over and walked to the trees of Russia.

Walking through the forest, the darkness overwhelmed the light. Walking over the bushes and messy terrain snow, Zero was careful not to leave to visible of a trail of his footsteps. He came to a small dirt path, deprived of snow. The path had tire marks and footprints as well. Traveling along the path, Zero heard a generator running sound near him. Stealthy approaching along the path, he heard the humming becoming louder. After a few minutes of walking, bright lights enveloped the shadows before him.

Looking up, he saw searchlights on a small tower going back and forth in a steady pattern. The harsh light lit up the shadows of the trees. Right next to the tower was two patrolman making rounds fifty feet from the tower. Matching the patterns perfectly, he then made his move.

Moving quickly and quietly in a crouched position, Zero made it just in time in the trees when the light covered the area he was just in a second ago. Moving deeper in the trees, be came across another watch tower and a lone patrolman. Just a few hundred feet away, Zero went lower so that he won't be spotted. Next to the patrolman was a wooden shack, possibly a place to take a break. The patrolman was dressed in full gear: a helmet with a visor, ski mask, a vest, ammo magazines, combat knife and clothing. On his back was a sturdy AK-47 with a sight.

Then a voice came, out of sight from Zero.

"Эй, Борислав, поэтому у вас есть любой из них на Я." [Hey Borislav, so you have any of them on ya?] asked a patrolman, who had similar gear to the other patrolman, but didn't have a ski mask, went up to the lone one.

The lone patrolman, seemed to be Borislav said something back. "Да, у меня их много!" [Yeah, I have plenty of them!]

Borislav then went into the wooden shack. Rummaging sounds were heard as the patrolman waited. The lights of the watch tower shined brightly over the area. Then a rush of wind caught up snow and sent down a chill the patrolman's spine. Pulling multiple small coughs, Zero seized the opportunity as the patrolman coughed.

Reaching just in time in the shadows of the trees, Borislav stuck his head of the shack.

"Сколько ты хочешь то?" [How much do you want though?] he asked the patrolman.

"Эххх ... четыре. Я думаю, что четыре достаточно." [Ehhh... four. I think four is enough.] replied the patrolman.

Borislav went back into shack and came out seconds later.

"Хорошо, вот вы идете." [Alright, here you go.] he said, handing four cigarette packs to the patrolman.

"Благодаря человеку." [Thanks man.] the patrolman said, gladly accepting the packs.

"В любое время." [Any time.] Borislav said.

Now out of sight from the second watch tower and patrolman, he came to the gates of the Russian stronghold.

"Z is at the objective." a voice said. "Approximately 1000 feet away."

A huge screen in night vision stood above a room. Showing a huge stronghold and a small blinking strobe as Zero. Vast forests can be seen as the RQ-170 drone flew over the Russian base.

"Copy Overlord, Z is nearing the objective." the receiver said as he saw the blinking strobe take action.

Outside of Russian Base

Zero heard motorized vehicles approach the gate. Taking action, he waited for the last of the convoy to stop. In one swift motion, he slid underneath the heavy truck and clung on with his hands. The monstrous vehicle's engine vibrating as it was in stall. Gripping on the metal bars, the trucks started to slowly proceed into the base as patrolmen waved them in.

Coming along the concrete walls of the tall base, Zero pulled out from under the moving truck and scaled the wall silently and swiftly. Now on the first level of the wall, he proceeded to go into the heart of the base.

Unlocking a vent, he went inside the pitch black darkness. As he slid down without being able to see his own hands in both of his face, he turned his night vision on as thick sliver metal was going up in his vision. Reaching an end, he used his hands and feet to slow his descend. Now on a flat surface, he went prone and crawled in the hot vents of the hostile base.

Moving closer, he looked in the horizontal lines of metal of the vents, he saw Russian soldiers in cafeteria eating. Chatter and plates clattering filled the air. With ease, he pulled himself fast to another vent. It looked to be a storage room as he looked in the horizontal lines. Opening it, he lowered himself in the dimly lit room. Mops and cleaning supplies were scattered. Kicking the junk aside and turning off his night vision, he approached the door. Opening it quickly he leapt out and closed the door and put his back on the door. Looking to the sides, there wasn't anything hostile, nothing. Bright lights above lit the hallways and there weren't any shadows for him to hide in. When Zero was about to open the door, voices were heard.

"Ха! Это было весело!" [Ha! That was hilarious!] a voice said.

"Я знаю! Это был гений для нас, чтобы сделать это! [I know! That was genius for us to do that!] a second voice said as it got louder.

Zero with no way to hide, he looked around for a place.

"Но вы думаете, он в порядке?" [But do you think he's fine?] the first said asked.

"Если он получает сознание, да." [If he gains consciousness, yes.] the second one replied.

Two soldiers without gear approached the hallway Zero was in with the storage room door.

Passing the door, Zero was hiding above the lights and kept still as the two soldiers passed.

Pulling himself down, he softly met the floor. Hiding after groups of soldier, Zero finally made to the power box. Pulling out a charge, he placed it nicely between the cords. Looking around, he placed more in good spots. Afterwards, he made his way to the armory. Reaching for the door, it was locked. He then got miniature charges and slid then under the door. After an hour of this process, the base was planted with charges.

Making his way back to the storage room to the vent, Zero reached for the door.

"Эй! Вы!" [Hey! You!] a voice called out.

Zero turned to see a soldier aiming his gun at him.

"Руки вверх!" [Hands up!] the soldier called out, gun still up.

Zero then calmly raised his hands and the soldier approached slowly. When the soldier was within arms reach, Zero quickly twisted his body around and grabbed the soldier's helmet and hurled it towards the ground. In the hit, the soldier held the trigger and bullets sprayed. Zero, having control of his arm, twisted it and the spraying stopped. Zero then got a pistol from his holster and fired one fatal round between the eyes of the russian soldier.

*BANG*

The soldier dropped dead with the fatal shot.

"Там в нарушитель!" [There's an intruder!] voice said.

Multiple soldiers came from the corner and started to fire. Zero maneuvered into the storage room and into the vents. Zero then placed the pistol back to get a better grip on the metal vents.

Sirens were turned on as Zero quickly raced to the top. Using his arms and legs, he climbed with ease. Reaching the vent, he pushed it and got out on the flat wide floor.

As soon as he got out, a helicopter was hovering, waiting for him. Then the gunner started firing.

Rounds of bullets fired from a machine gun as Zero dived into cover. The bullets ricocheted and tore through the metal, the only cover Zero had.

"Z is compromised! " Overlord said as the image of a helicopter was shooting on the blinking light. "Repeat, Z is compromised!"

0333 October 27, 2030

Outside of Russian Base

Zero placed the pistol back and an object morphed from a small machine from his hip. Out of a dim black light, Zero manifested a black SPAS-12 shotgun. Zero stepped out of cover and quickly retreated. In response, the gunner moved his fire to the place Zero was. Zero then sprinted out of cover and jumped off the first story and shot the powerful gun in midair. Taking out the gunner, Zero landed on the ground. But soon was targeted by infantry on vehicles. Guns were shot and Zero had no where to run, he was forced to run toward the base's entrance.

Shooting down soldiers, the alarm grew louder and soldiers started to appear frequently in more places. Making his way in the base, Zero sprinted into a small, wide metal chamber. Soldiers saw this and started shooting into the chamber. Bullets whizzed past Zero as he ducked for cover. Getting out of cover time to time, he shot a soldier. But with each shot, two soldiers replaced the first one.

Soon, the small chamber was filled with soldiers with their gun aimed at Zero's cover. A small click was heard as fragmental grenades landed near Zero. In quick response, Zero ricocheted the grenade off the ceiling and took out a group of soldiers. Then, about eight grenades pelted near him. Before he could get to them, a stun was thrown and Zero became distorted for a few seconds. The fragmental grenades exploded, scathing Zero. His vision blurred, he reached for the detonator. Another stun was thrown and Zero pressed the button of the detonator. A huge explosion ensued as vehicles were taken out along with the helicopter. Zero's vision was bright and it went dark.

"Z is down..." Overlord said as the light faded away. The explosion took the whole base and a huge radius around it. The vegetation disappearing by a bright ball of fire. "Repeat... Z is down..." Overlord said softly as the explosion continued.

Zero's vision came back as he felt himself thrusted forward into a bright blue vortex. With his hands in front of him, he couldn't control where he could go. Pushed by an unknown force, everything went black for Zero again.

In what felt like a few minutes, he was on the ground, his visor fogged by the dirt on the ground.

"Ugh..." Zero said as he got up and wiped the dirt off his visor. "Where am I?" he asked himself as he got up.

Getting up, he looked to see a bright blue sky and lush fields of grass before him. Looking to his left was a chain of tall icy mountains and on his left was a dark forest. In the middle however, Zero spotted a tree in the middle of the terrain. Taking out a scope, he scanned to see if life was around. On the a big tree, a size of a house in the far distance with many things of all sorts. Seeing a wooden shack and a platform on the top of the tree, Zero knew someone or something was living in the tree. Taking out his shotgun, he slowly approached the tree house in this strange new world.

OLD A/N: Yep, this is it guys! :D What do you think about this? Thanks for reading! xD And Happy Thanksgiving!

UPDATED:

[Command's story with Zero will unfold later in the story.]

THE REASON: By reading and playing Call of Duty: Black Ops 2, I found the plot to be extremely confusing if it blended with my story. So I made very few changes such as the year and when the mission takes place. The old edit showed Zero doing the mission in the middle of the War.

And the plot is more than just complicated... it's SUPER complicated! Which makes it interesting... No?

And I apologize if you come across a typo. Please PM me if you find one and I'll fix it as soon as possible. :)

Read on! And please review!
