Kingdom Hearts: Key from chaos

A/N: this is a new Xover for Kingdom Hearts and Sonic the Hedgehog, this will include my Sonic OC Rage as well as the main Kingdom Hearts characters. This will take place after what would be KH:III's final battle against Xanhort. So with that explained let us begin

~Yen Sid's Tower~

Mickey, Sora, Riku, and Kairi were standing in front of Yen Sid who was sitting in his chair, Lea was leaning on the bookshelf in the corner of the room

"I fear that Xanhort may not be gone yet…" Yen sid says stroking his long beard

"What do you mean Master Yen Sid?" Mickey asks the elderly wizard

"New activity in The World That Never Was concerns me that the old Organization members have returned" Yen Sid replies

"But if we defeated Xanhort then how could they have come backl?" Mickey asks concerned

"I fear he made it out of the Realm of Darkness… now it's what he plans this time and how the worlds will respond this time…" Yen Sid sighs

~Meanwhile in Angel Island on Mobius~

"ah… It feels so nice to finally get a decent vacation after all the conflicts the past few years…" Rage yawns laying under a tree looking out at Wave Ocean

"I hope we can get some decent rest this time." Tikal chuckles putting sun screen on her arms "It's the perfect time too, with Angel Island being over Wave Ocean this time of year."

"Still though…" Rage trails off "What is this weapon? I mean it reminds me of something I've seen before but it's still very different…" Rage was holding a Keyblade in his right hand one that looked like his normal weapon 'The Blade of Chaos' but with keyblade traits.

"I wouldn't worry too much about it, Rage" Knuckles chuckles "If it can cut down an enemy then it's a perfectly fine weapon."

"How about a thousand enemies?" Tikal asks looking off the western side of the island

"What do you" Rage sits up and takes the sun glasses of his face and before he could move them bellow his chin he saw what it was a swarm of black monsters (Shadows just so you know) "Mother of god…"Rage gasps gripping the Keyblade tighter "Guess its party time!" he chuckles jumping up in a burst of fire and leaps into battle

Back at Yen Sid's tower Yen Sid's eyes shot open in surprise

"What is it?" Mickey asks almost instantly

"Heartless… they're attacking a new world…" Yen Sid gasps a bit

"Well tell us where and we can go squish them!" Sora chuckles

"It's called Mobius." Yen Sid sighs at the hyper youth

"Let's go!" Donald quacks jumping into one of the Gummi ship seats of the hovering gummi that was just outside the moon shaped window. Sora and Goofy soon followed and the small ship flew off

[Mobius]

All was peaceful in Westside City a mid sized town known for one of it's denizens. Rage Chaotic the Hedgehog the renowned Guardian of Chaos. Ever since Knuckles the Echidna perished Rage took his place. Normally Rage was on Angel Island but today was different... today Rage was at the grave of his sister Christina Chaotic. Five years ago today was the day she was killed... by Rage. That would be one day he would never forget and he wished it had never happened but there was no other way. She had chosen to walk a path of Darkness and that put them in a death battle.

[Music Roxas Kingdom Hearts II]

"I am sorry things had to be this way..." Rage sighs laying a bundle of roses at Christina's grave as a dark gray hedgehog walks up to him and puts a hand on his shoulder. It was Christain the Hedgehog one of Rage's best friends at least now. Christain was once one of Rage's worst enemies but when his Dark Power was taken by Dr. Finitevus and lost in reviving Mephilies Christain remained with Rage and his pals as a protector of Mobius. "Hay Christain..." The crimson hedgehog says to him

"Hay Rage." the dark hedgehog says putting some roses of his own down "She was a noble hedgehog that met an unfortunate end..." he says "Fate did not deal her a fair hand and like me she was consumed by the darkness."

"Yeah..." Rage says softly "But you got out of it much easier then she did..." he looks at the tombstone and looks up as he feels the rain hit his fur. But he did not care his sister meant more then a small storm. Rage pulls a long coat from his bag that looked like an Organization XIII coat.

"Where did you get that?" Christain asks the red hedghog

"I found it in a shop on Dark Mobius the owner said he had found it in the city streets." Rage says putting the hood up

"Well I am heading home I can't stand the rain." Christain says as he walks off. A few minutes go by and Rage puts the hood back down feeling the rain subside as he stands up a horde of creatures appear.

[Music: Night of Fate Kingdom Hearts]

"What the?" he asks looking at them in surprise "Dark Spawns?!" he says as his weapon The Key to Chaos appears in a mix of fire an light "No... these are something else..." he says slicing one with it and what looked to be a heart comes out of it. Although he was shocked he had no time for thinking he had to get rid of these things and fast!

After a while of slashing and casting magic or chaos powers Rage finishes off the last of the creatures as his blade disappears. "What in the wide world of Mobius were those..." he wonders putting the coat back in his bag as the rain had passed and all that remained were clouds. He turns to leave but his ear twitches and he turns to see a man in a coat like the one he was just wearing. The hood covered his face and he appeared to be looking at Rage. "Who are you?" Rage asks looking at the mysterious figure who remains silent. "Answer me!"

"This world... has been connected..." was all it said

"huh?" Rage looks at him with an angered look "What do ya mean?" he questions

"You possess the Chaos Emeralds they can grant ones wishes am I right?" it replies and Rage's eyes light up as he reforms his weapon

"I have no idea what you are talking about!" Rage yells in defense "Now you better begin explaining before things get messy!"

"You understand so little..." the figure chuckles looking at the hedgehog putting his hood down... it was tall man with an X like scar and vivid blue hair"A heart that belongs to light will fall to darkness such is the fate of all..."

"Alright that's enough!" Rage yells leaping for the man in attack but he is blocked by a large claymore made by the man who forces Rage back with a guard break and strikes him hard.

"Chaos Counterstrike!" Rage yells warping behind the man and attacks him with a fury of strikes before launching him with one last powerful hit sending the man into a nearby tree. "Had enough yet?" Rage asks him as another hooded figure appears from the darkness

"Isa quit fooling around we have done what we need to The Heartless will take care of the rest. It is time to return." it says and the man apparently called Isa follows the other through the doorway of energy

"Wait!" Rage yells running after them but it disappears before he could reach them. "What was that all about... and how did they know about the Chaos Emeralds and what are these Heartless?" Rage asks himself as his ear twitches at a nearby presence and he turns to see a large black beast with a large heart crest torn out of the center with small black creatures like some of the ones he had faced earlier. "Are these Heartless?" the crimson hedgehog looks at them before he leaps to attack the large one who hits him out of the air. "ugh!" he grunts getting up as the large beast forms a large ball of energy that begins to consume everything. "Oh no!" Rage says knowing he was unable to do anything.

[Music end]

[Meanwhile in the Gummi Ship]

Sora was piloting when Yen Sid contacts them "Sora alter your course to Traverse Town the word I wanted you to go to just disappeared no doubt it it the work of Organization XIII." the old wizard says and Sora nods as he turns it around to Traverse Town

"Gwarsh what do you think happened to the citizens?" goofy asks

"They would become heartless if they don't end up in Traverse Town." Riku says looking off in the distance to Traverse Town. Soon they reach the world and land in The Third District and leap out of the ship.

"Do ya think anyone from this Mobius survived?" Goofy asks

"Hard to say." Riku replies "Not like we knew of the world before."

"I feel bad for whoever might have lived there." Sora says as they open the door to the first district and they find a young teenaged male on the ground. He was wearing a dark gray jacket with two red stripes in the center. It was unzipped and under it was a dark green shirt with a black R on it curved on the tails. Under that was a belt with various pouches and two small bags one was open and a could of gems had appeared to fallen out of it. The dark blue pants were stained with blood and his shoes a dark red. His hair was spiky and crimson red. In his right hand gripped by the gray fingerless glove was a sword that looked a lot like a Keyblade but there was no key-chain so it could not be a Keyblade.

"Look!" Donald was the first to see him as the four run over to the kid

"Is he okay?" Goofy asks

Riku shakes him "Hay are you okay?" he asks as the teen opens a pair of emerald green eyes.

"Ugh what...what happened?" he asks looking around "What the where am I?!" he panics looking around and standing up feeling himself "Human!" he thought aloud feeling himself "The Chaos Emeralds!" he gasps as he looks around on the ground for them. When he finds them he puts them in the open bag on his belt and picks his sword up.

"Hay we were talking to you!" Donald yells at him and he turns around

"Huh?" he says "oh my bad sorry."

"Are you okay? We kind of found you laying here." Sora asks

"I am fine... but who are you four and where am I? The last thing I remember was fighting this guy in a black coat I think his name was Isa and then as he retreats with another these things the two called Heartless attacked. I took most out but then this huge one plunged my world into a dark abyss and now I wake up in this town." he explians "My name is Rage Chaotic."

"Black Coats?" Riku asks

Rage nods "Yeah just like this one" he pulls the coat out of a pouch and uncurls it

"Organization XIII!" the four gasp

"You know about them?" Rage asks

"Yeah they cause trouble in all the worlds." Riku says "So would you happen to be from Mobius?"

"Yeah." Rage says "I think I am the only one here too... I cannot sense any others." he sighs "Now these Organization XIII where are they?" he asks

"Dunno they are all over." Sora says

"We should get going" Riku says "We cannot let them get too far ahead of us."

"Yeah if the Organization gets too far then we will lose them!" Donald says

"Let me come with you!" Rage says looking at them

"Why?" Riku asks

[Music Sora Kingdom Hearts II]

"Well I may not look like much but I am a skilled fighter. Besides I can be of aid to all of you my knowledge of other worlds is vast and I know darkness better then anyone I have been fighting against it my whole life in order to protect Mobius." Rage explains "besides if you need anything repaired or enhanced I'm your guy. Expert in engineering and weapon enchantment."

"Well Sora?" Riku asks "Your call."

"You can come Rage, we will need all the help we can get." Sora says

"Right." Rage says keeping a tense look

"You should loosen up Rage" Sora says

"Come on and smile!" Goofy says and Rage looks confused but then the four make a goofy face at him getting him to laugh

"Okay" Rage laughs "I see," he smirks as they head back to the Third District and get in the Gummi Ship "Wow this thing is amazing..." Rage says looking at it "Makes me think of my Chaos Freedom MK I..."

"Well hang tight!" Sora says taking off
