As the summary suggests this is a darker version of our beloved Sonic the Hedgehog. I know it may have been done before and I know the story title might sound a bit cheesy... but hey, I have always wanted to write a FanFic about the dark side of Sonic the Hedgehog. I apologize if the title has been taken already or if any of the contents of the story has been done already; I have not read a single Sonic story here.

With that being said, I really would like to ask that if you read this story please post a review about what you thought, or if you have any ideas on how to help me improve my work; Remember that the readers are the writers greatest ally in their works.

I will not tolerate any reviews stating that this story is just plain stupid, or I am stupid for doing this or that. I want nice thoughtful and honest reviews... remember... think happy thoughts.

So besides the fact that Tails and Knuckles fans will want to hurt me before this chapter is over... please enjoy this FanFic which will be updated from time to time. God bless.

Sonic the Hedgehog: Chaos Factor

Chapter 1: The World Reborn

It is a bright and sunny day at Station Square. Tails is out stocking up on food for the next week as he has two bags in his arms, with several more bags in a small floating device behind him. He takes an apple out of one of the bags he has in his arms and takes a bite out of it. While licking his lips due to the taste he puts the apple back in the bag before getting ready to take the train back to his newly created base on Angel Island.

"I sure am glad Knuckles agreed in letting me set up my new home on his territory. Echidna's can be very territorial…" he sighs to himself while stepping on the train.

As the doors make the normal sound while closing behind him he finds a seat nearby and places all of his bags close by. As time goes by he looks out of the window while watching the clouds pass overhead. The sun shines through the clouds and Tails is forced to squint his eyes to continue looking upwards. It was a very cheerful day, but something was in fact troubling the young two tailed fox. The evil scientist Eggman had not attacked for some time now, and it was starting to worry everyone. Sonic is gone searching for the evil Eggman in hopes of figuring out his next plan.

"Sonic has been gone for awhile… I wonder if he has found anything out." Tails mutters to himself while feeling helpless at the same time.

As his mind wanders off the train comes to a halt suddenly, jerking Tails out of his deep thoughts. Being curious he leaves his bags of food behind to see what is going on in front of the train. When he arrives he can plainly see Eggman's standard robots blocking the path of the train. Nobody could go outside to try to stop them because they were above water on the rails of the train track. Without hesitation Tails slips out of the side door of the train car and flies towards the robots who instantly take aim at the young fox.

"Looks like Eggman is finally trying to pull something." Tails mutters to himself while pulling a small ring out from his left glove.

It suddenly enlarges as Tails places it over his right arm, which causes it to form an energy cannon. As the robots begin to open fire on the two tailed fox he begins to dodge the bullets with ease. When he finally finds an opening in their patterns he opens fire himself blasting one of the robots into the water below. While the numbers of the robots begin to lower Tails is finding is easier to take them down. Soon the last robot falls into the water which is soon followed by a small explosion underneath. Tails then presses a button in the back of the cannon that turns it back into the small ring from before. While he flies back into the train car he puts the ring back into his left glove where he can use it again later.

"Thanks for the help Tails! Now we can be on our way!" the conductor says with glee while everyone else sits down.

Once again Tails finds himself in deep thought over Eggman's next move, but soon after the train arrives at the Mystic Ruins. A lot has changed here since their adventure against Chaos. All around there is stands for food and rides as if the Mystic Ruins had turned into a Theme Park. Ignoring the growing crowd Tails begins to spin his two tails which lifts him up into the air with his bags of food close behind him. He makes his way through the caves that leads towards Angel Island. Although there was a small Theme Park nearby, Knuckles never would allow anyone to step foot inside of the caves due to it being a direct path to his territory. The brilliant fox lands near a large circular rock that is blocking his path. He then moves a panel back near the rock and presses a few keys before the rock slides out of place.

"The only way you can stay here on my Island is if you help me protect the Master Emerald." Knuckles' voice echoed through the fox's thoughts.

Tails has done just that. Throughout the entire Mystic Ruins area Tails had placed his own personal security system that only acted against Eggman and his vast amount of robots. However many times this system has also saved the lives of the people who have gotten lost or nearly eaten by wild animals. The fox walks through the entrance where the giant rock had once rested. Tails then turns around to press a few more keys before the rock slides back into place as if it never moved. The tunnel continues for a few more steps before Tails can see the light of day again. He holds his right hand above his eyes while looking at the sky again. He then makes his way to another cave to his right which has nothing inside but a small panel on the ground. He steps on it which in turn teleports him directly to Angel Island high in the sky above all of the clouds. Once on the island he can make out Knuckles guarding the Master Emerald in his normal grumpy manner. The island was the same as always, only Tails had built a house for himself behind the altar of the Master Emerald. It was a house big enough to fit him and a guest, with a large lab next to his house for his technical work.

"I'm back Knuckles." Tails calls to the Echidna while tossing him an apple.

"Any news yet?" he asks while catching the apple.

"No, nothing yet." the fox replies while walking towards his home.

The Echidna watches Tails walk inside before lying back down to continue his version of guarding the Master Emerald. Tails is already putting the food away and preparing his next meal, not being able to stop thinking about what Eggman is up to, or where Sonic is. Even Amy had left to help figure out what Eggman was up to. That was also the reason why Sonic left days before Amy did, to put a good distance between the two. On cue a crash is heard outside of his house so the two tailed fox rushes outside to see what is going on. On the altar lies Knuckles knocked out as the fat Eggman climbs out of his hover craft still wearing his normal clothes.

"Eggman!" Tails shouts to the mad scientist which causes him to turn his head.

"Ah Tails… it is so good to see you after so long. I trust you have been well my young genius?" Eggman asks him while tilting his head a bit.

"What did you do to Knuckles?!" the fox questions him while flying towards him. He lands near Knuckles who is barely breathing at the moment.

"I just knocked him out that is all. There is no need for you to worry about him." Eggman assures him while walking towards the Master Emerald.

"Why did you want the Master Emerald this time Eggman?" asks the fox as Eggman turns to him.

"I have been researching… waiting for the right moment to strike. I knew that if I waited long enough... Sonic would not be here to stop me. My research led me one day to discovering something grand… something that you and Knuckles will help me with." Eggman explains while walking closer to Tails.

"Why would we help you with anything you loser!" Tails shouts to him while activating his energy cannon once again.

Eggman then reaches to grab the cannon and pulls it off of Tails' arm. The scientist then tosses a small octagon shaped device with spikes on the edges to Tails. It latches onto his arm and suddenly gives him a violent shock which causes him to black out.

"He-he-he… very soon the new world will start. How fitting that this world will end with what started it." Eggman laughs to himself while his robots place Tails and Knuckles inside of his hover craft.

After Eggman climbs back inside he controls the hover craft above the Master Emerald. He presses a button in front of him which causes a large crane to lower down and grab the Master Emerald. As he flies off with the precious gem in his grasp the island free falls down towards the Earth. A few moments later the Theme Park nearby can hear a loud crash as they look around with curiosity. To their terror they take notice that Angel Island had fallen, causing a massive wave of water to engulf the Mystic Ruins. Soon after a familiar blue hedgehog runs up to the scene, and to his horror everyone there was killed due to the tsunami.

"Eggman…!" the hedgehog grits his teeth. "You've gone too far this time!" he adds before running off towards Eggman's new base, located underneath Station Square.

Sonic knew where his enemy was, even though his enemy was not aware of what Sonic knew. Sonic comes across the railroad track that was not destroyed by the wave of water and jumps on the top of it, following it all the way to Station Square. Halfway there Sonic meets with many of Eggman's robots which attempt to stand in his way.

"I don't have time to deal with you metal losers!" Sonic shouts to them while running past them.

This causes a sonic boom that rips the robots to pieces in a matter of seconds. Sonic rubs his finger under his nose with a cocky attitude while continuing his way. While arriving at Station Square a few moments later he takes notice to Eggman's robots destroying homes and even killing some of the people there. The hero inside of Sonic instantly springs into action as he does multiple homing attacks on the enemy robots nearby. He instantly begins to charge his light speed attack before unleashing it upon all of the robots in the area. The massive army of robots blow up within seconds of each other as Sonic lands, catching his breath all at the same time. Sonic then finds a man hole that leads to the sewers nearby and drop down below. He speeds along the stinky waters that is leading towards Eggman's base. Suddenly he free falls for a few moments before spotting the ground below him. Sonic begins to rapidly spin in a circle motion causing a small cyclone to keep him from smashing into the ground.

"Now to find that base!" Sonic tells himself before running off.

He can barely make out lights ahead that are moving back and forth, showing Sonic he was on the right path. Many more robots stand in his path but Sonic runs right past them in hopes to save his friends from Eggman. Sonic instantly crashes through the wall of Eggman's base setting off the alarms.

"It seems I underestimated his detective skills." Eggman speaks up while looking at his security feed off of his main viewing screen. At that time Tails and Knuckles both wake up to a violent jolt of Chaos flowing into their bodies. They are strapped to the Master Emerald inside of a barrier of Chaos, generated by the Master Emerald. The room is a dark red color due to the alarms going off. Eggman is above them inside of a safe room where nothing can hurt him.

"What's going on here?!" Tails panics as he struggles to free himself.

"Let us go!" Knuckles yells at the doctor while struggling himself.

"Don't struggle, it will all be over soon." Eggman tells them as Sonic suddenly bursts through the door behind Eggman.

"Let them go Eggman! I mean it!" Sonic shouts to the doctor with anger in his voice.

"Why Sonic… you're always so easy going… why the sudden change?" Eggman jokes with him before pressing a button behind him. Sonic bursts through the protective glass that was meant to protect Eggman and rushes towards his friends. The barrier made out of Chaos knocks him back however.

"Sonic!" Tails and Knuckles both cry out in unison as the hedgehog continues to attack the barrier.

"It's no use Sonic, you can't break through. It is made of pure Chaos and cannot be broken unless I command it to be." Eggman tells him. Sonic watches in horror while the being called Chaos Zero begins to ooze out of the Master Emerald and surround Tails and Knuckles.

"Human…" Chaos Zero suddenly speaks as shock hit's the faces of everyone but Eggman.

"I am here mighty Chaos Zero." Eggman replies.

"Do you wish to sacrifice these two in order to carve a new world?" Chaos Zero asks Eggman as Tails and Knuckles stop struggling suddenly. Sonic takes notice to their eyes going white completely.

"I do, Chaos Zero." Eggman replies once again with an evil smirk growing on his face.

"Those who are to be sacrificed… do you wish to give your life for his purpose?" Chaos Zero asks Tails and Knuckles.

"Yes… we do…" they reply shocking Sonic.

"What are you guys talking about?! You will die if you agree to this!" Sonic shouts to them as Chaos Zero snaps his head towards the blue hedgehog.

"Silence!" Chaos Zero shouts as a wave of chaos hits Sonic and throws him against the wall.

"You lose Sonic! Ha-ha-ha!" Eggman laughs as Chaos Zero then fully engulfs Tails and Knuckles forming a solid ball of liquid inside of the barrier.

"No!!" Sonic screams while taking notice of Tails and Knuckles both looking directly at Sonic with a sad expression on their faces.

As Eggman's laugh echoes through Sonic's thoughts there is a bright light that surrounds Sonic. When the light finally dies down, Sonic looks up to see another frightening sight. Before him is a land covered in ashes, the buildings are destroyed and covered in plants, showing no sign of life.

"Eggman! You just made a huge mistake in killing my two best friends! I swear… I will get you myself!" Sonic screams throughout the land.

End of Chapter 1

Now since you are reading this I assume that you have already read this chapter. I hope you enjoyed it, or maybe it inspired you for your own FanFic.

At the moment I am looking for a couple of good created characters. The thing about creating the entire story yourself is that sometimes it is hard to come up with a created character. I am looking for two created characters to finish the lineup for this story.

Remember kids, not all created characters have to be hedgehogs that run super fast or can turn Super! I am looking for well thought out characters with a background to him/her. If you just want to create the character and let me take over from there I will create the background for that character. Credit for the character will of course be given to the original creator and it will be stated above the chapters title. I must say though I do not really care for demon possessed characters or those with satanic intentions... no offense is meant at all. So if you send me information on a character along those lines... I will most likely pass it by.

Please also remember that when you give your created character to a writer, the writer has full control of your character. So if the writer wants your character to die or is put in a coma that is the writers choice, not your own.

Now then if you are interested in having your created character placed in my story, send me a message!

I look forward to hearing from anyone interested!
