Hey, everyone! Welcome to my first fanfiction ever!

First off, this story is based on a game loved by many Cartoon Network fans called "FusionFall", but this story will be almost completely different from the game itself. Anyway, I hope you enjoy this story, and you can review/favorite it if you want! Now let's jump right into the story!

In the faraway Andromeda Galaxy, there is a world that is much different from ours. This planet is about the size of our Earth, and its name is Arkadex, which was based on "Dexter's Ark", a prophecy created by the early humans there. It is a world where humans and anthropomorphic animals co-exist together, where heroes and villains battle it out over giant cities, where imagination can actually create beings, where magic actually exists, and where the levels of technology were so high that things people would normally consider science fiction were just starting to become true.

The main capital of Arkadex was a metropolitan city named Townsville, which was the main hub of all transportation, heroes, and technology on Arkadex. But Townsville was also the hub of many different villains. Villains such as a megalomaniacal green mutant monkey, a strange red demonic creature, an space alien tyrant, and gigantic monsters were just a small percentage of all the villains. Thankfully, the heroes could stop all of them.

All the technology that spewed across Arkadex came from a place called Technology Square, or Tech Square for short, which was located in the northeast part of Townsville. Tech Square was the location of two rival science companies: Dexlabs and Mandark Industries. Dexlabs, the more popular of the two, was run by the boy genius named Dexter, who originally lived in Genius Grove, but moved his lab to Tech Square to expand his company. His massive intelligence (it was around 10x greater than Einstein's) allowed him to create technology that most people would have not even imagined to be possible. Shortly after his company was founded, he threw modern technology right out the door, creating a new age of technology called the "Advancement Age".

But over the past few months, Dexter was constantly locking himself inside his lab, and whenever anyone did see him, he was normally muttering to himself while drawing extremely complicated equations that only he could understand, and he normally didn't want anyone to be near him. Eventually, people began to get suspicious as to what Dexter was doing, but some people believed he was working on something great, which he indeed was.

There were other cities other than Townsville, such as Marquee and Bravo. All those cities combined with Townsville forms a great metropolis called Downtown, taking up almost half of the entire southwestern continent. But it's in the eastern section of Townsville that our story begins.

It was a bright and beautiful June afternoon in Townsville. The sun shone onto the road and towering buildings, making them glow in the sunlight. As groups of hovercars sped northward along the road, some turned toward Offworld Plaza. Of all the people on the street, one specific 14-year old boy exited one of the apartment buildings along the street. This 14-year old boy had bright blonde hair, and wore a black-and-green lined long-sleeved shirt, with a white vest on top. He also wore dark green pants with bright green lines going down the sides, green shoes with black straps, and shaded glasses which covered his eyes. Not long after he exited the apartment, he saw a Dexlabs hover-limousine coming from his right. The instant the limo parked outside, he got in and buckled his seatbelt. Almost immediately after that, the limo hovered in the air, made a full circle, lowered back on the ground, and took off.

As the taxi started hovering down the roads, the kid remembered the transmission he and his family had received from his dad, who worked at Dexlabs. He had said that the kid, or as said in the transmission, "Mark", had been accepted as the volunteer for the time travel experiment. He continued to say that Dexter had assured that the farthest Mark should be sent into the future is a day or so, even though they were planning for the time machine to return only a few hours after departure.

After only a few minutes of driving, the limo passed by a small park. But it wasn't a normal small park, because Mark looked out the window to see an observatory on top of a towering volcano. Right when he saw it, he felt a major feeling of hatred towards the villain whose base of operations was inside the observatory, Mojo Jojo.

Mojo Jojo was a mutant monkey who originally worked with Prof. Utonium, but after the sudden creation of the Powerpuff Girls, a trio of powerful superheroes, came much smarter, and turned evil due to "neglect", or at least that's how he put it. He was one of the most persistent villains on the surface of Arkadex, constantly attempting to destroy Townsville or take over the world, always being prevented by the Powerpuff Girls. But a few months ago, during a battle with Mojo Jojo during a storm, Buttercup, the green-clad member of the Powerpuff Girls, had been knocked into the ocean, and was never seen since. Even though the Mayor of Townsville had sent search parties multiple times, every search had no results. Mark decided to take it out of his mind as the volcano got removed from view by the surrounding buildings.

After another ten minutes of driving, Mark could see Dexlabs down the road. Dexlabs had a very interesting structural design, and, interestingly enough, a house was on top. After driving to the front steps outside, Mark got out, and the limo sped away, back to where they had came from.

Mark looked across the gigantic garden lined by giant solar panels around its border to see the rival company of Dexlabs, Mandark Industries, which was created by Mandark, Dexter's long-time rival. Just like Dexlabs, they had robot helpers similar to Dexbots, except they were red and black instead of blue and white. Those bots were called Mandroids.

Mark always thought Mandark was a mad scientist, due to his persistence to be better than Dexter. Mandark, for all Mark knew, was probably watching him right now, and pondering what he was doing here. Mandark had made other technological breakthroughs, like a laser pistol that creates portals to other dimensions, but he didn't know about Dexter's time travel experiment. When Mark looked behind himself and saw that a security camera above Dexlabs' front door was looking straight at him, he knew that somebody must be watching him, either Dexter or a Dexbot. If it was either, then he knew that someone was coming, so he walked toward the front doors, which opened up instantly.

Mark walked into the white lobby room, which he had been in a few times on the annual "Bring your Kid to Work Day". Mark then looked at a glass cabinet on the right of the room, which said, "Best Inventions of Last Year". The inventions he saw were many strange devices, including an unnamed vortex machine, which Mark believed to secretly be a copy of the time machine engine.

"You have an appointment?" a robotic voice said. When Mark turned to where the voice was emanating, he could see a desk with a Dexbot behind it.

"Uh, yeah. I've arrived for the time machine experiment."

"Let's see," the Dexbot said as it pressed a button on the underside of the desk. Almost instantly after, some kind of camera instantly popped out of the ceiling. Mark instantly knew he was gonna be identified via facial scanner, so he took off his shaded glasses to reveal his emerald green eyes, which were a common trait in Mark's family. Suddenly, a blue light was projected onto Mark's face. Mark tried as hard as he could not to close his eyes, and only a second later, he could hear the scanner saying,

"Identifying... Identified: Marcus Xavier Emeron."

"Searching through Dexlabs Database... Time Machine Experiment Volunteer: Marcus Xavier Emeron."

Once the light stopped, and the scanner went back into the ceiling, Mark's vision was very yellow for a couple seconds.

"You may wait in one of the waiting room chairs. I shall inform Dexter that you have arrived," the Dexbot said before the circular panel in the wall behind it moved, revealing a passageway. The Dexbot turned around and went forward, before the panel closed again.

Mark walked to his left toward the waiting rooms. Mark sat in on of the blue couches, and looked at the clock on the wall, which said: 2:32. He waited for about five minutes, wondering how they would use the time travel mechanics. Suddenly he heard something coming from his left.

"Sorry about the wait," he heard a voice coming from his left saying. "Just putting some final touches on the time machine."

When Mark looked his to left, he could see a redheaded boy walking up to him, from a passageway opening out of the wall. This boy seemed to be about eleven to twelve years old, he wore a white lab coat, and he was much shorter than Mark. He also wore big glasses around his eyes. Mark knew this kid was Dexter, as he had seen him before when visiting previous science conventions.

"It's fine, Dex," Mark said.

"Interesting nickname- Anyways, as you know, I have created the first time-stream teleportation technology of its kind. A time machine, to be precise!" Dexter said with confidence. "The quantum state of matter in which you take up will be sent through a hole in Space-Time-"

"OK, OK, I think I get it," Mark said. "No offense."

"None taken. OK then, let's go," Dexter said, followed by the same passageway that Dexter came through opening quickly, and the two walked in.

After the metallic plates of the wall quickly closed, the two walked down the bright blue hallways, lit up by what looked like nothing. Inventions we also floating in mid-air, or attached to the walls. Mark wanted to ask, but at the same time, he wanted to keep his mouth shut to avoid a gigantic lecture. At that moment, Mark heard a humming sound, and when he looked forward, he could see some kind of partially holographic floating robot. This robot seemed to awkwardly have many humanoid features, including holographic hair. Its legs were also fused together, and what would be its feet was replaced with what looked like an upside-down UFO.

The robot began to speak, "I see the volunteer has arrived." When the robot saw Mark had a confused facial expression, the robot continued speaking.

"Excuse me, let me introduce myself. I am Computress, Dexter's personal assistant and overseer of production in Dexlabs. Before Dexter moved to Tech Square 3 years ago, I was Computor, who controlled the entire lab without a mobile body. But when Dexter moved from Genius Grove to Tech Square, instead of moving Computor's hardrives from lab to lab, he transferred all of Computor's hardrives into a mobile body, which is now me."

"Oh, she also helps me with a couple of important experiments sometimes," Dexter added. Mark sort of understood why Dexter referred to Computress as a "she", but at the same time, he didn't. But he went along with it anyway.

"Let's get going, all the Dexbots are waiting," Computress said before turning around and floating toward a gigantic metal door with a force field around it. Dexter quickly walked and placed his pointer finger on a scanner, before moving to an eye scanner and a voice scanner.

"INDENTIFICATION CONFIRMED: WELCOME, DEXTER."

The force field quickly shut down, and the door swung open, thankfully not toward the three. When Mark walked in, he could see a ramp leading downward into a gigantic room. All the Dexbots in the room looked around to see the three at the top of the ramp.

As Dexter, Computress and Mark walked down the ramp, Mark looked around what seemed to be the main room. There seemed to be a lot of inventions throughout the place, as well as some sort of gigantic machine in the center of the gigantic room, which Mark guessed to be the time machine. This machine had a spherical geometric design, and two antennae moving out of the top. There were many wires and pipes connecting to the machine, and Mark wondered how they were planning to activate it. Mark could see his dad among small groups of employees inside safe observation rooms, but he focused on the time machine. Computress quickly hovered to a control panel, and pressed a button, which opened the hatch. Mark was about to go in, but suddenly Dexter stopped him.

"Hold on, Mark, you need this," Dexter said, as he handed him some kind of reddish watch, which instantly strapped itself around Mark's left wrist, and its central area began to glow blue.

"Why do I need this?" Mark asked.

"That's your communicator, and also a locator beacon. You'll need it after the time travel, because Computress will be messaged of your arrival in the future. You can go on in now." A group of Dexbots wheeled in with a stepladder, and placed it in front of entrance to the time machine. As Mark walked up the stepladder, he felt a sense of hesitation, that he didn't want to go in.

"I'm...I'm... should I go in?"

Suddenly the other corner of his mind came to help. "MARK! Don't give up now! You've come this far! You know there's no way back! Take it all the way!"

After hearing that message, Mark threw that sense of hesitation out of his mind, and he walked into the time machine. As soon as he heard the impenetrable glass door shut tight, Mark knew there was no going back. He turned around to see Dexter at the control panel Computress was at, except it seemed to have moved to the front of the time machine now.

"Can you hear me in there?" Dexter said while peering into the machine.

"Yes, I can hear you just fine," Mark said, as he looked around the interior. He noticed that he could see the outline of a clock, with the first 12 roman numerals in their appropriate positions. The inside of the time machine also consisted of a turquoise color. Mark looked through the large front window to see his dad in the central observation room, talking with other employees, frequently smiling at Mark. Suddenly, a giant scanner popped out of the ceiling, and scanned the entire interior of the machine, including Mark. When Mark looked outward from the time machine, he could see a monitor showing the percentage of scanning in the time machine, which seemed to rise rapidly, by about 75% per half-second. By the time Mark noticed it, the scanner had already completed processing.

While Mark was waiting to go forward in time, something crossing the doorway entrance caught his eye. A... girl crossing the door entrance and peering into the room?

Mark's dad, Harry Emeron, had also seen the same thing. He didn't know if he was seeing things, or if it was some sort of experiment.

"What was that?" Harry said, pointing at the entrance to the main room.

"What do you mean?" another employee said.

"I thought I saw a girl, outside the main room door."

"Wait, her?"

"Welcome to the first experiment of time travel technology by Dexlabs, everyone!" Dexter said, getting applause from the Dexbots and lab assistants, and getting the attention of Harry and the other assistants. "After this experiment, time travel will have officially been experimented!"

After more applause, he continued, "Now, with the help of our volunteer, Marcus Emeron, Dexlabs shall make history!"

After another boom of applause, Dexter turned around and began to press buttons on the control panel. But Mark saw something different. Mark noticed a blonde-haired teenage girl with pigtails, in a pink dress, sneaking down the entrance ramp with a very curious expression on her face.

As the time machine's main engine began to power up and produce rather loud noise, Mark's dad, in the observation rooms, did not know what the girl was going to do.

"Dex... Dexter?" Mark asked as he pointed to the girl. But Dexter was so focused on the experiment that he didn't even hear Mark. Mark tried to yell his name multiple times, but to no avail. He even tried to pound on the machine's glass door, but even that didn't work.

"COMPUTRESS!" Mark screamed at the top of his lungs. Due to Computress's highly sensitive hearing system, Computress managed to hear Mark. Mark instantly pointed to the secondary system of buttons for the time capsule, where Dee Dee was looking at all the buttons. When Computress saw the girl, she tried to notify Dexter, but Dexter could barely hear her, so he went on with the operation.

"Prepare for launch!" Dexter said with a smile on his face, unknown of what was about to happen. "Launching in T-minus three... two..."

"Ooooh! What does this button do?" the girl said.

Of everything he had not heard from the girl, Dexter heard that question. His eyes instantly widened, and he began to emit a facial expression of panic. It was the worst thing he could have heard during a crucial experiment like this. When he turned to the girl, she was already pressing buttons on the secondary control panel, which, if pressed at the wrong time, could resort in disaster. Suddenly his facial expression turned to fright, and then anger.

"DEE DEE?! GET OUT OF MY LABORATORY NOW! HOW DID YOU EVEN GET IN HERE?! DON'T PULL THAT LEVER-"

But it was too late. Dee Dee had already pressed many buttons involving Space-Time travel length, and pulled the High-Energy Output Lever, switching the co-ordinates and destination in Space-Time completely off. At the same time, alarms began to go off throughout the room. The Dexbots were all in panic, and the people in the observation rooms were in terror.

Meanwhile, the time machine began to spark. Steam pipes outside and inside the machine were breaking, and steam began to cover the time machine and cloud Mark's vision. Lights were flickering throughout the room, and the time machine's inner lighting system began to lose control. Mark didn't have a clue of what Dee Dee had done, but it must have been drastically bad.

Mark's dad quickly ran through the entrance to the main room, and down to the time machine, which had begun to shake violently. Mark could barely keep his balance, with all the tremors inside the machine. Then, a really powerful tremor flipped the time machine upside-down. Mark quickly fell to the ceiling, and tried to balance himself, even though the time-machine was somer-saulting all over the place.

"What can you do?" Harry asked in terror, afraid for Mark's safety.

"I don't know! Dee Dee's frozen the controls! DEXBOTS, RESTRAIN HER!" Dexter screamed. Dexbots instantly stopped Dee Dee and pulled her away from the control panel, and placed her in a plasma containment field. Even though Dee Dee couldn't get out, she still was laughing a lot.

Dexter ran over to the control panel, as the time machine flipped itself again, and began to hover in the air. Nobody in the room could see Mark, but only the silhouette of the time machine surrounded in the cloud of steam. Since Mark couldn't see anything, due to all the steam, and that the time machine was completely dark, he just waited for the time travel to occur while he lay on the floor of the time machine.

"HOW CAN WE STOP THIS?" Mark's dad screamed.

"Hurry! Shut off all the power!" Dexter said.

Sparks were flying out of the time machine, and the machine's intense density began to bend light as it glowed brighter and brighter. Before anyone could even get to the power control system, blinding rays of white light enveloped the entire room, with enough brightness that the light could be seen from miles upon miles away. When the pulses of light finally receded, all that was left of the time machine was only a couple fried bolts. At the same time, the lights exploded, and the room went dark, before the emergency lighting was activated.

Dexter pounded his hand on the control panel in anger, nearly cracking it. He didn't even care about his valuable work being lost. All he worried about was Mark's safety. Meanwhile, Dee Dee had lost all her laughter. The containment unit instantly opened, and Dee Dee fell onto the floor. But she didn't get up, or run away in laughter. She just sat there, staring in fear. It was almost like her brother wasn't even there, because his personality had never been like this.

"Dee Dee..." Dexter screamed as he turned around. "WHAT THE HECK IS WRONG WITH YOU? EVERY SINGLE FREAKIN' TIME I HAVE AN IMPORTANT EXPERIMENT IN PROGRESS, I CAN'T HAVE IT BEING SUCCESSFUL! NO! YOU HAVE TO ALWAYS SCREW IT UP! HOW DID YOU EVEN GET IN HERE?!"

Dee Dee tried to speak, while trembling with fear. "You... you left the door open..."

Dexter turned around to actually see the main room door had been left open the whole time.

"OK, that was an error on my part, but you're still-"

"No, Dexter, please! I'm sorry!"

"Oh yeah, like I'm supposed to believe that!" Dexter yelled. "Do you have any idea how long I worked on that machine? But that's nothing compared to the real reason I'm mad at you!"

"I'm-I'm really, really sorry, Dexter-"

"REALLY?! TELL THAT TO HIM!" Dexter yelled as he pointed at Mark's dad, who walked toward Dee Dee with an even angrier look on his face. When he screamed at her, he sounded almost demonic.

"DO YOU HAVE ANY CLUE WHAT YOU'VE DONE! BECAUSE OF YOU, MY SON IS GOING TO FLY TO AN UNKNOWN TIME!" He put his face in his hands before screaming again. "You... are the worst! I... I will... You're a disgrace to humanity! MY SON'S LIFE IS IN DANGER BECAUSE OF YOU! I... I... hate-"

"OK, Harry, I think that's enough, but she still deserves punishment!" Dexter said. He pointed to a squad of Dexbots. "You two, get her out of here now! Add extra security measures to every single entrance!"

Two Dexbots instantly picked up Dee Dee, who was now crying, and wheeled her up the ramp.

"And make sure to keep an eye on her, Dexbots!" Dexter said as the main doors slammed shut. As he walked out of the room through another door, he said, "Computress, where did the subject end up in Space-Time?"

After a pause, Computress said, "Based on the charging time, the buttons Dee Dee had pressed, and the brightness of the travel, Mark has ended up in the center of Tech Square, and has gone forward in time by approximately..."

"How far?"

"1 year and 234 days..."

Well, I hope you enjoyed this first chapter! What do you think will happen to Mark? Where do you think he'll end up? All these questions will be answered in the next chapter!
