Chapter 1 – the chaos gems, darkness formed

Tails POV

2 months ago Sonic battled Eggman again, he beat Eggman but the Chaos Emeralds were split in 2, reforming into the chaos gems, Sonic was able to find half of them, the ones he found all have positive energy in them, which can only mean that the others must carry the negative energy…

"Cream" I said shouting out of my workshop, she moved in to my house 2 days after her 18th birthday, she had a very big row with her step father Vector, they're still not on talking terms without exchanging insults, she's been my workshop partner for 2 years now, sometimes she surprises me with her inventiveness.

"Yes Tails" she came in holding a try with food, she had cooked us dinner.

Normal POV

"Thanks Cream" Tails said while kissing her.

"Don't mention it, how's your research going?" Cream replied while sitting down on a chair next to Tails.

Tails was busy pondering at his computer "The Chaos Gems Sonic collected are all positive energy, so that would mean…" he said while thinking of the possibilities.

"The others are negative?" Cream said, finishing Tails trail of thought.

"Yeah, I love it when you do that" Tails said.

"Well I have been learning, oh by the way Sonic called saying that…" Cream was interrupted by the phone ringing.

"I'll get it" Tails said as he got out of his chair, he walked over to the phone and pressed the loud speaker button "hello?"

"Hi Tails long time no see," a calm voice spoke over the phone.

Tails recognized the voice and replied "hi Luke, when did you get back here…?"

Luke answered truthfully "hmmm I felt the chaos energy spark, I though I would check what's going on, I tried to call Sonic and Amy, but I got no reply…"

Cream answered "Sonic and Amy are on a date."

Luke's voice sounded with surprise as he spoke "oh hi Cream, Tails you should have warned me I was on loud speaker…"

Tails realized his mistake and replied quickly "sorry Luke, anyway the Chaos Emeralds got split in half".

"So the energies would also be split in half?" Luke questioned the theory.

Tails answered "sadly yes, we have the positive side, but not the negative".

"I see, so…" Luke's words were cut off as it sounded like he had just been hit in the stomach".

"LUKE?" Both Tails and Cream yelled as they heard the sound, wondering what had happened to their friend.

With Luke on a building in SS

"I see so…" Luke stopped as an all too familiar heartbeat could be heard in Luke's head, he held his head as he gasped for air, he screamed as if he had been hit hard enough to be kicked through a building.

"Let me out!" a dark and treacherous voice boomed in his head, it echoed with evil and darkness.

"No, you don't control me, I defeated you, you should be dead!" Luke shouted in panic as he fell to the floor in pain, he stopped himself and was kneeling on the floor with both his hands on the ground.

"You may have my power, oh Tribal of duel destruction, but I will not become a memory!" the voice boomed as Luke's body began to glow an ominous dark red and his eyes begin to go yellow and cat like.

"Get out of my head, you have no right to be there Ambition!" Luke cried out as his hair keeps changing from red to blue to brown.

"Some day, I will enact my revenge" Ambition said menacingly as the glow faded, Luke's eyes change back to their glowing green state and his hair changes back to normal.

"Luke, are you there?" Cream said from the mobile with a worried tone of voice.

"LUKE ANSWER ME?" Tails shouted, hoping to catch Luke ear, Luke walked over and picked up the mobile and spoke in to it "sorry guys, I just had a mental fight…"

Tails spoke with a curious voice "huh? Anyway what was the thing you were about to say?"

Luke though about what he was talking about before he was interrupted "oh, there is a chance Eggman might have the remaining gems…"

"I know…" Tails said in agreement.

After some talking Luke decided to go to Tails's house, Luke spoke to inform them "I'll be over in 2 hours, ok?"

Tails and Cream both replied "ok Luke."

With Tails and Cream

The sound of the phone getting disconnected was made as Luke had hung up.

Cream spoke as she remembered her and Tails's old friend "I haven't seen Luke since he fought Eggman with us, I wonder what he meant when he said a mental battle?"

"I don't know…" Tails reluctantly answered not having a clue.

With Luke

"It's good to see you again, Luke Naferus" an evil and dark voice spoke, Luke knowing all to well who it was answered "why are you here?…"

The voice answered clearly, knowing the increase in challenge "I felt the negative energies, they're just too tempting."

"I will stop you, you know that." Luke said with confidence.

"Nothing is certain, farewell, until me meet on the field of battle" for some reason as the voice stopped speaking the air seemed to clear, it was as if darkness had left, for the moment.

Luke pondered the matter while walking to the edge of the building he was standing on and looks down to judge the distance from the ground floor, after little time Luke spoke to himself the answer "3 miles, a good warm up…"

Luke put his left foot back and jumped of the building, he ran on the side of the building while approaching the ground floor, while running down the building his eyes begin to glow White, he jumped from the building and begins to free fall and spoke words that he knew well "Drangorth, grand white dragon, fuse with me, my guardian!".

His red shirt and swords disappeared as his skin colour turned light gray, 2 white stripes develop on each cheek going to the back of his neck and formed 1 big line that runs down his spine, his hair went ghost white as his hands turn into ivory talons with a large saber like spike on each elbow, two more saber like spikes come from his shoulder blades on his back forming two smaller spikes on each side of the larger ones…, he opens his eyes to see the highway not but 50 meters away from him, the spikes on his back are hollow as they ignite to form some type of jetpack, he levels himself off 30cm away from the road and takes off into the sky, and spoke cheerfully with a grand voice as if he had become a dragon himself "a train is just too boarding sometimes, ha, ha…"

With Sonic and Amy

While walking home from a restaurant Sonic spoke up "Hey Amy, has today been fun?" his voice was calm while he prayed in his head Amy had enjoyed herself.

"Yeah today's been great…" Amy replied cheerfully as she saw stream of white fire went across the night sky. She spoke at the sight of it and pointed "wow, a shooting star…"

"Make a wish," sonic said to himself, he caught her off guard as he kissed her after speaking. After a while the kissing stops and they walked back to their apartment, when they arrived Sonic opened the front door.

Sonic walked into the kitchen while speaking "I'm getting a drink, you want one?"

"Sure, what do you want to watch tonight?" Amy replied, she heard Sonic thinking as he tried to reply "how about Pirates of the Caribbean 2, Dead Man's Chest?"

"Ok…" Amy replied cheerfully, Sonic walked to the fridge smirking, one of the things both of them had in common were certain films, Amy walked to the DVD collection and began to rummage through it, she was surprised it had gotten messy as she found the film and picked it up, something rattled "I hope the DVD's not scratched" she said as she started to open the box she shouted to Sonic in the kitchen "Sonic, the DVD box is rattling, I hope that…" she never finished her sentence as a piece of paper and a ring fell out of the box, she picked up the ring and read the words on the piece of paper that was attached.

Amy Rose

Will you do me the honor of becoming my wife?

Will you marry me?

Sonic T. Hedgehog

As she put the ring on her finger, Sonic entered into the living room, she ran to him kissing him on contact and knocking him on to the floor with one of her trade mark bear hugs, she finally broke the kiss and spoke with a hyper and cheerful voice "of course I will marry you Sonic the Hedgehog, I love you…"

Sonic replied to Amy while he held her around her waist "I love you too Amy…"

And though the world seamed at peace, not all was as it seems for in the shadows lurks evil.

With Eggman

Eggman spoke to himself while sitting in his chair "Hmmm with the power of the negative chaos gems…"

"You can control the cosmos with a dark, sinister and unnatural army!" the dark voice echoed as it seemed to come from everywhere and nowhere.

Eggman quickly got up with his blaster ready as he spoke with an unnatural panic "Who's there? Show yourself!"

A man walks out of the shadows in black armor, on his back was a black shield and on his right hand side was a sword with a dark handle and purple gemstone.

Eggman spoke mistaking the man for someone else "what? LUKE? What are you doing here…" he paused for a minute as he saw the red scar on the left hand side of the man's face, he spoke again to correct himself "wait you're not Luke…"

The man spoke to answer the evil doctor's question "precisely doctor, I am Shadow Slyther, in a way I am a dark copy of Luke's ancestor, but that is beside the point, the Chaos Gems have enough power to cause resurrection to happen, but once all of the gems are used they will try to find their counter parts, and that incisive hunt will begin once again."

Eggman questioned Shadow Slyther's words "resurrection? just what do you have in mind?"

Shadow Slyther began to reveal the first part of his plan "well…"

With Luke

As Luke flew to Tails's house he spotted some ruins, as he passed one of the walls began to glow, he landed and changed back to his normal form as he walked up to the wall and began to read the inscriptions, he spoke out loud as he realized the dialect "that looks familiar to me, but where have I seen it?" Luke moved his hand across one of the symbols as he touched it the symbol spoke in his head "as a…"

Luke moved his hand away as he realized the language, he spoke to himself he solved his question "ah… Zidane's native Language", Luke pressed his hand on the wall and moved his hand across the wall, as the words appeared in his head, Luke spoke them out loud to grasp them better.

"as a back up to our findings, we created a second Invincible so that the dregs of souls would be kept for safe keeping" Luke moved his hand away as he finished and spoke as he though out loud "So there's a second invincible that is connected to the one in Gaia, I wonder how everyone is doing…" Luke lost himself to his thoughts as he realized the great danger "wait if the negative chaos…" he remembered what his arch nemesis Shadow Slyther said.

The words rang in Luke's head.

Flash back

"Nothing is certain, farewell, until me meet on the field of battle"

End flashback

With Eggman and Shadow Slyther

Eggman spoke as he had discovered new things about his enemies "so Luke is an off worlder, who has had a hand in defeating some powerful foes?"

Shadow Slyther spoke angrily as his hatred grew "precisely, with my dark power and the negative chaos gems I can resurrect these people and you can rule the cosmos…"

Eggman smirked as he spoke "I see, I think my dimension ripper will do just that, it had the power too summon beings from other dimensions even from the after life." Eggman pushes a button, as a machine that looks like a door opens up. Eggman places the chaos gems into the machine, after he finished he spoke "sadly we need to know who we want to summon, also I only have seven of the chaos gems, they won't try and reform till the other half are used"

Shadow Slyther replied "I'll use my dark power and the second Invincible to find the people we're after, we won't have to worry about the other half of the gems unless Luke catches wind of my plans too early, then it will just be more of a challenge that I can accept."

Shadow Slyther places his hand on to the machine as dark energy flowed into it, somewhere under the sea an old ship began to light up, after a minute the ship established a connection with Eggman's computer.

Eggman smirked as he spoke "the process is working, as planed."

The machine exerted a blinding flash of light, as the light clears 11 figures were standing in front of the machine, one of the figures with blue hair and a light voice spoke "Well, this is unexpected, to come back from the far plane so soon…"

Another figure spoke as he turned his head to look at the Blue haired figure "Hmm… I sense Mako, but no reactors…"

A figure walked forwards with his hand on his chin while speaking "my boy, it is obvious we are on another world…"

The left most figure looked around while speaking up as his feather like hair moved in motion with his head "we were brought back with the dregs of soul, hmmm I don't sense my brother but…"

The middle figure spoke as his red hair glowed "arrr my destruction twin, so he is on this world, I can't wait to enact my revenge!"

Shadow Slyther spoke up having slightly lost his patience "yes, he… is on this world, and so are some powerful items in question… oh where are my manners, it's good to see you all again, everyone this is Doctor Eggman, Doctor Eggman this is Sephiroth, Loz, Yazoo"

while he pointed everyone out he stopped at the figure with two gunblade katanas and paused for a moment, he smirked evilly as he quickly changed the subject "ahhh this would be Weiss or should I call you Hojo?" a form of Hojo appears next to Weiss and began to speak "we both share this body but you may call us what you want."

Shadow Slyther snickered at Hojo's remark as he continued to point people out "I see, this is Azul, Rosso, Nero, Kuja, Seymour, Shuyin, his darker half anyway and Ambition."

Eggman questioned Shadow Slyther's early statement "this is the army?"

Shadow Slyther quickly and evilly answered "oh no they're just the leaders, the army I'm talking about will be transported here by them, once I give them a little dark power boost."

Ambition's eyes glowed with exitement as he voiced his question "so this is all out war?"

Shadow Slyther smirked and answered "yes."

With Luke

As Tails checked outside, he saw Luke approaching his house, Luke stopped just in front of the door, slowly turning around, he quickly turned back round and shouted at Tails "get down!"

Luke pulled Final Edge off his back in time to slice an incoming Fireball in half, as the smoke cleared he took a good look at his opponent with surprise he spoke "no way…"

Weiss questioned Luke's reaction "Surprised to see me?"

Luke calmly put his Final edge on the holster on his back while speaking "no…" Luke removed his Holy swords from their sheaths on his sides and got into a fighting position.

Weiss smirked at Luke's reply as he also got into a fighting position "Good."

Both Luke and Weiss shot forwards towards each other, on contact they began exchanging blows and blocks every second, as Luke jumped back Weiss shot with one of his gun blades at Luke, Luke put one of his swords in front of him slicing the bullet in half as it exploded in his face, as the dust settled Luke's hair was glowing blue, his eyes Bright green.

Weiss smirked at this transformed state and spoke "so this is your Tribal form, I must say I'm impressed."

Luke began to notify his surroundings and spoke in his head "I got to make sure I don't go too far, Tail's workshop is way to close for me to become careless, I can't lose another friend because of my powers." Luke replied wittily to Weiss "well I'm glad you're 'impressed."

Weiss huffed as he pointed his gun blade at Luke and pulled the trigger shooting bullets out of the gun blade, Luke quickly jerks out his hand and blows up the bullet in Weiss's face just as it left the barrel, Weiss coughed as he had fully taken the impact, as his voice cleared he spoke "I see, you're serious, well…" Weiss lifted his head as if someone was talking to him, he spoke out loud as if he was talking on a mobile "I understand, ok I'm returning now" he looked back at Luke and smirked while speaking "we will meet again." with that Weiss vanished in to thin air.

Luke's hair turned back to its natural brown colour as Tails ran up to him and spoke "who was that?"

Luke didn't answer but spoke "Tails call everyone, I'll explain everything when they get here."

Ok I just finished re-doing this chapter, I'm fixing a flaw that a reviewer pointed out, thanks for that I never knew, please leave all criticism with a reason for the burning, don't be childish and leave stuff like "it's crap".

Please give me some decency and leave helpful flaming with a good, well explained reason.
