Act IV : Part I

~ True Chaos ~

Sonic and Shadow both briskly backtracked from their original position as the green ball of spines shot out to them like a bullet. Nearly dashed by the emerald hedgehog, the two looked to one another and nodded. Sonic launched himself forward, spinning in midair and curling into a tight ball, while Shadow burned some Chaos energy into his skates, making them flare brightly, before he took off and attempted to land a roundhouse kick at their attacker.

Scourge smirked and readied himself, going into defence, his electric blue oculars flickering back and forth to the two heading his way. Already registering their signature moves, he side-stepped to his right as the blue blur charged his way, followed by ducking down to the ground till his body was parallel to the ground to avoid the flying boot aimed at his head area. As he dodged their combination, time seemed to slow down in between as the smirking green hedgehog jolted back up, and whirled a back fist out of nowhere to Sonic, who's still in midair; after that, he swung in his spot counterclockwise and shot his left leg out to direct a returning kick to Shadow's exposed abdominal area.

Time resumed again as he took action, the two caught off guard by his retaliation and didn't had enough time to retaliate. As a result, his counters met their target and flung them a couple of feet away, surely to leave some sort of bruise where it had made contact due to the immense force that was placed in those returns. Once he sent them flying, Scourge straightened his posture once more, his feral grin wide and displayed his joy at the demonstration. He clenched his fists firmly, chuckling to himself.

"I've grown powerful now, Sonic… Ya can't defeat me with those old tricks of yours! Same goes to you too, blackie!" cackled their foe as the pair groaned in pain after they managed to catch themselves on time as they were about to hit the terrain near the forest. Their feet had dug on the loose ground, skidding themselves to stop before they could topple down.

Sonic found himself breathless after the impact, gasping for air twice before he could regain his composure, yet his ribs screamed in agonizing silence. He winced visibly when he had attempted to stand up. Narrowed emerald orbs peered to his side to notice his partner in battle to be in more or less in the similar situation as him.

"Shads.. You okay?" What the hell is wrong with me? Why am I feeling so weak all of a sudden with just one attack? He pursed his lips in annoyance to himself and to his enemy's jovial expression.

Shadow, meanwhile, slowly yet carefully stood up in one leg, huffing an irritated breath before glancing to the other from his side vision. He nodded once as he furrowed his eye ridges together in a deep expression. "Looks like we underestimated the bastard."

Sonic can only grin as he perceived the usual raw tone of the bio-engineered lookalike. Ignoring his own circumstances, he failed to notice the faint sign of what was causing his dwindling state.

"Heh, it's about time we get serious," the blue Mobian hero grinned, "No more Mr. Nice Guy."

"Agreed." Shadow formed his hands again into fists, bracing himself for an immediate counterattack.

Seeing their determination setting in their visages, Scourge can't help but let out a laugh before. His shoulders quaked as his booming, insane chortle echoed around him that made Amy and Cream tremble in fear, the pair cowering at their spot. Despite the bravado that Amy had showcased, she didn't forget and was completely aware the whole time of her own limited power, and somehow she knew deep within her, that she can't win against them in a battle. No matter how she dislikes the idea of just watching and doing what she can to protect herself and Cream, she can only rely on her friends who could actually stand a chance against the three.

For Sonic and Shadow, they merely glared at him and prepared to attack him again, this time doing a combo. Scourge, meanwhile, leered at them mockingly. He waited for them to make their move in anticipation, knowing what he would do at once.

There was a still moment in between before the trio exploded into action, dust and dirt were kicked into the air and the wind whooshed like mini tornadoes within their fray, dancing and stirring along with their blurry movements. Green, blue, and black with red all dashed before everyone's sight like ribbons as the combat lasted no more than a minute before the smoke had eventually cleared and the trio had emerged from their half-concealed brawl with dissatisfaction.

Scourge had now a couple of bruises and ruffled fur in some places where he was obviously been hit or grazed by something hot. He wore a mask of fury and hidden rage as he glared daggers towards the gasping duo.

It wasn't easy for Sonic and Shadow to land an impact on the green huffing creature, but they were certainly a bit gratified at the sight of what their actions had done. Beaming, the azure speedster was even more dishevelled and obtained more wounds, some blood actually can be spotted here and there. He wasn't staggering on his feet. Yet. It would take a lot more pounding before he could collapse and for anyone who knew the hedgehog, he wouldn't just let them have at it without expecting a strenuous fight from the other. Meanwhile, Shadow didn't sustained much injuries like Sonic, but the few bruises that actually got to him was apparent and showed their damage when he tried to move his limbs. He grunted in discomfort as he felt the familiar stinging pain and at the same time, felt his regeneration kicking in.

This guy.. Is more and less like Sonic, but it's obvious that he's evil… Where did he come from? He took a swift glimpse to his side, crimson reflecting the condition of his counterpart. Well, at least, it's safe to say that these two idiots are both head strong and stubborn.. If we keep going like this,this idiot would harm himself more…

Wait. Why do I care? He shook his head out from his contemplations when his hyperactive senses alarmed him of the change of plight. And it's not good at all.

"Hmph.. You're taking way too long, Scourge…" hissed Mephiles the Dark as he proceeded to bound over to the huffing, aggravated hedgehog. "The… Master.. won't be happy if we are to delay any further."

"Whatever!" Scourge snarled viciously to his ally, yet he allowed the other to step forward and face the two.

Shadow scowled at them in exasperation while Sonic gave a slight frown at Mephiles joining the fight. It's obvious that the outcome of their struggle had drastically shifted into the other's favour. It was difficult handling Sonic's evil twin, taking the two of them to actually par with him, but now that another one has been added to the party, Sonic and Shadow both contemplated that it would be no easy victory for them.

Alcaeus continued to watch over them, acting as a spectator for now, his golden irises glazing over the group, mostly to Sonic. Recognizing the immediate distress showing in his face, the ebony hedgehog maliciously grinned. Victory will be ours, no doubt about that.. But there's something else that I need to do.

He glanced to the other two of his companions and his features instantly turned sour and calculating. "Let's see how strong are these two with the amplifiers." He raised his hand before him, revealing a device at hand with a red dial button adorning its grey surface. Without any delay, he pressed the button and smirked at the chain of reaction that it had initiated.

Scourge and Mephiles both trembled as if triggered by something. The accessories that were hidden away in the darkness now came into light, appearing into forms of bracelets like what Sonic had on his wrist, sterling silver trinket with bright verdigris gem on the centre began to glow ominously. In a flash, it would appear that nothing has changed, but the atmosphere around the two seemed to waver, the air crackling as their impressive power threatened to dominate the space they're in. Sonic and Shadow both grimaced, their mind setting into autopilot mode.

Scourge howled in ecstasy as he felt the power surging in his veins. He threw an elated sneer at the two, sensing their anxiety emanating from their features. "Oh yeah, baby! Let 'er rip!"

Mephiles can only relaxed back to his position, but something was definitely at work as he focused on the heroes. "Hmph. Make this at least interesting, Shadow…"

-x-

"Not if we can help it!"

"Geronimo!"

As if to bring light to the grim situation, a couple of unlikely comrades burst out into the scene. A white encased with teal gleam flashed its way in front of the two hedgehogs in trouble, followed by a red ball of fur thundering behind it.

Sonic blinked his beryl optics to the newcomers poised before him in a defensive stance. Recognizing them at once, he looked at them in disbelief. At his side, Shadow groaned, both miffed at the idea that he would be requiring aid from am implausible acquaintance. He straightened his posture, despite the protests of his healing injuries, which seemed to be taking a long time to process.

"Hmph.. What makes you think we need your help," he voiced out begrudgingly, stepping forward as an attempt to brush them away from his path, but he was stopped in his tracks with a wave of their hand.

"Obviously just this once… You can't overpower them easily, Shadow," the echidna flashed him a serious look, their ally turning out to be a friend of Sonic, Knuckles. "I can faintly sense the power of one of the Chaos Emeralds on them."

"Knuckles is right." His companion agreed as he peered to his side, his topaz orbs aimed at the Mobian hedgehog. "There's something that I need to tell you, Sonic, but it looks like you need our help first."

Sonic released a deep sigh and nodded, the plight dawning on him slowly. "Yeah, thanks for the cover… They're powerful, so don't make light of them." He frowned as he readied himself.

Shadow grunted in complaint, but didn't say anything further, cluing at the words of the guardian. If what the echidna was true, then that explains the absurd power behind Scourge's counters.

How the hell did I get into this mess again.. Crimson orbs flickered to the source of their problem, the black-white quilled impostor standing just a couple feet away from their foe.

For Sonic, he put the question of Silver's presence in his timeline, and concentrated on the matter at hand.

"Let's go, guys. Let's show 'em what happens when they mess with our planet!"

"Alright!"

-x-

Half an hour passed, but to the hedgehogs and the echidna it felt like it's been forever. All were still standing on their feet, but they're shaking and obviously had received the bad end of their conflict. Yet, they didn't suffer and endured for nothing as they had in turn, managed to crippled Scourge into paralysis while Mephiles had shown indications of slowing down. Alcaeus gritted his teeth in anger, his hand grasping on the amplifying device. It was clear that he didn't anticipated the balance between their fight, even with the power of the Chaos Emeralds aiding his side. A "tsk" sounded from his lips as the ebon-white sibyl descended from his spot, landing behind the two. "Enough." I never thought that I would use this, but this has gone too long…

He swept his impertinent glower to the panting blue speedster, who's standing in front of his friends in an attempt to at least protect them as they tried to catch their breath. The Ultimate Lifeform won't be having any of that, moving to Sonic's side instead. "Your friends are in trouble if you don't run away," he told the speedster beside him. "They are after you, don't forget that, so don't let them catch you this easily."

"Shadow.." Sonic flickered a tired look to the black-furred hedgehog before his mouth curved into a half-hearted optimistic smile, "Yeah, I know… Who knows what they'll feed me if they catch me. Oh, the horror."

"Shut your trap and get out of here, is what I'm saying, idiot Faker," Shadow snapped at his presented sarcasm before he took off from his side, dashing towards their enemy with a set look.

"Shadow!" Sonic was about to bolt after him, but he was stopped when Silver clasped his shoulder in vain.

"Sonic, don't. Let him handle this," Silver staggered to a standing position again and gave him a reassuring smile. "We'll back him up and clear an escape path for you."

Knuckles also hopped back to his own feet slowly and sauntered before his rival. He nodded in agreement with the white furred psychic and eyed the trailing form of the Ultimate Lifeform. "Yeah. Don't let them get to you, Sonic. We're still capable of fighting and I assure you that we're going to win this."

"Go now before they regain their strength."

"Sonic."

The Mobian cobalt blue hedgehog clasped his fists together, his eye ridges furrowing in deep frown at the idea of leaving his friends. Something is obviously wrong with him if he can't even at least keep up with Scourge, but he can't afford to think the fault of his own being when their enemies is dead set on capturing him, and if they don't achieve their mission, then his comrades will be forced to face the consequences. Biting his lip, his jade irises met the golden orbs of the time traveler and the amethyst hues of the guardian before shaking his head in refusal.

"Sorry guys, but running away isn't my style…" He fixated them a confident smirk, but it was evident that he's clueless of how to defeat their opponents. "Besides, I'm just getting started…" He briefly glanced down to the adornment on his wrist, recalling the event that transformed the Chaos Emerald into a piece of worn jewelry. He's not the only who has a Chaos Emerald…

"Silver, Knuckles, buy me some time, will ya?"

Both of his friends peered at him and raised an eye questioningly before they bobbed their heads in acknowledgement and faced their adversaries once again. Once they blasted off, following the artificial hedgehog's series of barrage, they each took their turns to combined their strikes together to make them more effective and damaging. In turn, Scourge and Mephiles returned each chains with their own, the green rebel whirling into a ball and stirring the malevolent winds into their favour, creating small tornadoes while, the crystallized form blasted a flurry of projectiles to their way, some flying indirectly to where Amy and Cream was. The pink hedgehog expertly hammered the ricocheted bombardment on their end, the rabbit helping her by moving to where the recoiling shells can't reach her.

Sonic saw the danger that Amy and Cream were; however, before he can respond to their help, Knuckles had foreseen their situation a minute before Sonic did and sped his way to their direction, knocking off the rebounding spheres of detonation from their trail. Seeing this, Sonic let out a sigh relief before he went back to concentrating his own natural Chaos energy within him and tried to infuse it with the sapphire Chaos Emerald in his grasp.

Meanwhile, Shadow was parring against Mephiles who kept pestering him with long range attacks. But he wasn't the least troubled by it. His enemy's open fire was met with his own Chaos Spears sourced from his own Chaos energy. The forces collided as they met and exploded, creating bursts of fire in the dim, cloudy skies, like fireworks.

Silver, in the other hand, was facing against Scourge, using his telekinetic powers to control and manipulate the objects that were stirred by the whirlwinds caused by the rebel. They seemed to be evenly matched, but it was clear that Scourge was getting the upper hand bit by bit as he continued to cause more unnecessary damage to the environment more than Silver had expected, resulting into a surrounding, relentless attacks.

The blue speedster watched this take place in his spot as he felt the ephemeral wild energy of the Chaos Emerald flowing through him. At this point, anyone who's capable of sensing the fluctuations of Chaos energy were subjected to notice the strong pull. Almost everyone who's in the battle, except for Amy and Cream, grew aware of the steady rising of Chaos energy level to where Sonic is. Alcaeus jeered in anticipation as his golden orbs had fixated on the blue figure.

Finally!

-x-

As the familiar energy pulsed into him like a tender heat wave, Sonic can only tremble and withstand the sheer intensity of the force streaming through his soul before…

Wait.. What's going on?

You're mine!

What?! Ugh!This is..! No!

Sonic shuddered as he fell to his knees, wincing and groaning in agony as the golden light that surrounded him warped into a magenta hue. The fallen hero expelled a massive amount of force, the earth shaking below him as another tremor passed through the area accompanied by the discordance happening within the blue hedgehog and the Chaos Emerald. Sinister gales sprung forth and collided with the natural winds surrounding the place. Everyone had their gaze on Sonic as they beheld the sight before him.

Slowly, but surely, they remarked on the transformation that the hedgehog in question is going through. At that mark, Alcaeus made his move.

Shadow and Silver perceived the movement of their enemy as Scourge and Mephiles noted the impending charge of their assigned leader. The rebel grinned maliciously while his companion hovered in the air. Both followed suit, heading to Sonic. Shadow and Silver gave chase hurriedly. Not a moment too soon, they caught up with the two, leaving Alcaeus in the lead.

Scourge bounded over to the side, growling in irritation as Shadow attempted to tackle him. Silver got ahold of Mephiles as he used his powers to effectively halt the trek of the crystalline form.

"You're not getting anywhere!" Silver held on to the struggling form as he flickered his determined gaze to Shadow, "Shadow! That one..!"

Shadow frowned as he turned his head away from Scourge. "Shoot!" He immediately departed from the rebel's sight as he darted back in pursuit after the sibyl. The green hedgehog was about to follow, but was stopped by a swift side punch from out of nowhere. His face turned to the other side, the force strong enough to topple him to the ground.

"You're staying where you are, Scrounge " the red echidna cracked his knuckles as he stood over the surprised hedgehog. The rebel shrugged off his confusion easily and jumped back into position, snarling furiously.

"It's King Scourge, bitch!" He quipped back angrily as he charged towards the new contender.

Ahead of them, Alcaeus can practically snag the bewildered hedgehog in a few seconds, but he found himself pulling back as he picked up the thundering blaze of Shadow's skates behind him. Clicking his tongue in impatience. He swiftly turned to face him as he skidded into a stop, the soles of his boots treading harshly to the hard ground. He straightened his posture and prepared to take down the self-proclaimed Ultimate Lifeform.

"You never cease to amaze me with your perseverance, Shadow…" Alcaeus growled, throwing him a sharp glare, before he whipped out his weapon in plain view. A scornful smirk crossed his features, bright amber eyes reflecting the gleaming weapon in his hand, which was a short double-edged dagger with a red hilt. Strange engravings covered its side and glimmered under the faint light as he brandished it skillfully while Shadow poised for a launching attack.

"But it ends here now." The ebony furred foe relaxed, at the same time Sonic screamed in affliction, his wail echoing like a dismal alarm.

"AAAAH!"

-x-

His cry caused every heads to turned to its source except for the Alcaeus who's wearing a cocksure expression. There was a moment of silence before an outbreak occurred behind him where Sonic was, flames and rubble erupting from the terrain and surrounded the area in a hazy smoke. Once it was clear again, Shadow cautiously moved his glance behind his opponent, his ruby optics finding the malefic figure of his doppelgänger standing behind Alcaeus hauntingly.

Alcaeus huffed a breath and turned to where Scourge and Mephiles were, snapping his fingers, "Our job here is done…" That went smoothly as I've expected.. Now..

The two whom he had mentioned perked their heads in attention almost automatically as Alcaeus motioned for them. The pair throwing one last glower to their opponents before they made their escapades from their foes. Scourge darted out of from Knuckles' aim and rolled to his left, evading him altogether and sped his way to where the ebon hedgehog is, while Mephiles simply broke loose from Silver's invisible grasp and teleported in the same location.

Shadow stepped forward, sensing the recognizable dark aura of the Chaos energy emitting from Sonic. Damn… How did this happen?!

Act IV : Part II

~ Rise of the Darkness ~

In lack of better word, the Mobian heroes weren't fairing well as one would hope. Not only because of the strong enemies before them that caused the dawn of the apocalypse, but also at the emergence of a new formidable enemy from their fallen ally. From all of them, only Shadow, Silver and Knuckles knew the sudden turn of events and the potential catastrophe that would follow after.

Right when they were going to burst into action once again, a familiar voice calls out from above, sounding over the maelstrom and the whirring of engine.

"Sonic!"

Shadow flitted a glance to the dark heavens above his head and saw the blue biplane of a certain kit gliding from the direction of the other coastline. Silver and Knuckles flashed a look to one another before they stormed to their foes' way, determined to retrieve their friend back. The Ultimate Lifeform took off his eyes from the flying plane and followed after the two, his skates blasting golden Chaos energy, propelling himself forward.

Tails, aboard and piloting the Tornado, had at last arrived to the location that he was supposed to meet Sonic, Cream, and Amy, but somewhat dismayed at the ordeal happening below him. Questions and confusion flooded his racing mind, but paid no heed to it as a single thought passed through his processors and that was to save his friends. Firmly grasping the stick of his plane, he lowered his altitude and tried to land somewhere near and deserted. The plane began to tip down until it was appropriate to land safely beside the lush forest, where Amy and Cream were hiding. Once the fox made his landing as quick as he can, he jumped off from his seat and onto the sandy terrain that were left unaffected by the turmoil. He spotted the two girls hiding behind the bushes, out of harm's way, and the scorched landscape of the bay… Or what was left of it after what the group had done to the place. He could already tell that his comrades didn't fight an easy war, and it would seemed that they're not done yet.

Concurrently, Shadow and the others were dashing left and right as they continued their battle with their opponents; Shadow taking on Alcaeus, Silver against Mephiles, and Knuckles facing Scourge. The fair-furred fox observed them for awhile before drawing out his weapon of choice, set into joining the fray to rescue his friends. Though he's aware that he can't do much, he hopes that they would emerge victorious in numbers. After he made the decision of joining in, he charged forward and headed to where his friend is, wanting to make sure first of his condition. He had noticed that the blue hero wasn't in a state of fighting, failing to see the abnormality around his friend.

Out of the corner of his eye, Shadow detected the kit approaching the unconscious form of the speedster. As Alcaeus attempted to swipe at him with his dagger to his torso, the artificial hedgehog lurched back and jumped before he accelerated past his enemy and to the space between Tails and Sonic. Discerning the pattern of his movements, Alcaeus turned his heel back and leaped after Shadow.

As Tails was about to approach the still figure of his best friend, he paused in his steps and reached towards the "sleeping" blue hedgehog. Almost in an instant, he retracted his arm back as he felt a stinging pain running across his outstretched arm. Horrified and confused, he glanced up to his friend to see what was up, only to find in a blink of an eye that Sonic wasn't.. "Sonic" anymore.

Oh no… His cerulean oculars mirrored the familiar darkened fur of the once cobalt blue hedgehog. His quills are flared up and at this time, his dark aura that has been emitting for awhile now became noticeable to a naked eye. The fox immediately backtracked before he was swept away by a particular dark pelted hedgehog.

"It's best if you don't approach him for now," Shadow huffed as he landed back down a couple feet away from his bewitched counterpart. He put the kit down and faced Sonic once more, while the others took were busy dealing with the troublesome duo of evil. Alcaeus was yet again by the dark blue's side, smirking victoriously before the other two retreated to his side at once. Knuckles and Silver also did the same as they went to where Shadow and Tails were swiftly. The two conflicting sides intensely gazed at one another, sparks can be seen between them before the assumed conspirator of the armageddon stepped forward and flicked his wrist.

Suddenly, the air pressure dropped magnificently and there was a wild turbulence. The trio and Sonic started to hover in the air and were lifted up by a strange, unknown force, the gravity and other physics laws bending to their will as they floated.

Golden orbs flickered to Shadow and company, who watched in horror, as they steadily ascended to the skies. "I hope this is the last time that I see your face, Shadow.. Sonic will be the one to end this world and shall be the key to ultimate destruction of all universes!"

"It's no use stopping us and your fated doom," Mephiles hissed as Scourge beside him cackled at their win and the apparent mixed emotions of fear and anxiety displaying on the heroes' faces.

"Haha! All hail to the king, baby! This is it for this world!"

The Ultimate Lifeform can only stand by with the fellow Mobian heroes as the trio and Sonic vanished from their sight in a flicker of light. There was a moment of silence before Tails collapsed to the ground and Silver clenched his fist in defeat. Knuckles gritted his teeth and punched a boulder nearby, the surface breaking into several cracks before it exploded from the harsh impact.

"Dammit!"

With their friend taken away just like that, the group was left with nothing but crushed hope and trepidation. Amy and Cream eventually came out from their hiding, witnessing the entire conflict and its aftermath from the sidelines. They strode to where Tails is, their first instinct is to comfort the confounded fox, but even then they knew that nothing they say will soothe him from his shock. For Silver, he merely looked on to the group, saddened at the conclusion of their battle. They fought long and hard to stop them, but to no avail.

Is this really the future that this world chose..? He contemplated in silence, his gaze flitting to Knuckles, who's having a hard time to contain his frustration and instead, venting it out to the poor rubble lying close by. This is such a devastating loss… What do we do now..

"We don't have time to mope around."

Silver looked to the one who spoke up in a serious tone. Shadow turned to them with, eye ridges set.

Knuckles heard him and stopped, slowly facing him with an infuriated look before checking himself in, before answering, "Right… We need to save Sonic and teach those bastards a lesson.." Saying this, he pounded both of his curled fists together.

Shadow nodded in confirmation. Well, at least one of them isn't as crestfallen as the rest… Now.

"First we need to know where they've taken him. Which means, we need to go to the only source of information that we know…"

Silver stepped forward as Tails seemed to come back from his reverie. Resolve began to set on the group as they turned to Shadow, gaping at him as he assumed the being in charge. With Sonic gone, it's not like they're not capable of handling the saving the world matters, but often they need someone to be the acting "leader" for support and assurance. Sonic was their source of assertion and a go-to hedgehog if they require help. Although Shadow reflected a bit of the bitter side, their aptitude and sense of loyalty to protecting Mobius is almost alike.

They all gathered around and looked to one another. Amy and Cream both wanted to know what's going on, lost of what they're going to do.

"Right, but who's this source of information you're talking about?" Amy piped up.

"GUN, of course," Shadow replied, crossing his arms, "They're stationed not too far from where we are, but I don't think it's safe to travel on land." At this moment, he glanced to Tails, who caught up on what he's referring.

The genius kit nodded, "My plane has enough seats for all of us."

"Shadow, it's best if we share some information firsthand before we make any sudden moves," Silver joined in as Knuckles stepped behind him, agreeing.

"Yeah, I've already told Sonic and Tails about what I've perceived from the Master Emerald, and it might help shed light in our situation."

The Ultimate Lifeform bobbed his head casually as the group started on their way to the Tornado. As they hurried to their transportation, Shadow mildly contemplated the events in his head, pondering of what Alcaeus is planning. For some reason, the image of his nightmare last night kept replaying in his thoughts like an old film.

This is starting to make a lot sense, but at the same time, I'm as lost… Why is Sonic important to them? And what'sthe reason of their takeover…

I hope the GUN and Rouge managed to get some useful information.
