Chapter 378: Deoxys Vs. Mewtwo [Bonus]

~Third POV~

[Kanto Region, Viridian Forest, Team Rocket Airship]

The massive Team Rocket airship hung low over the Viridian Forest, a dull, metallic predator against the bruised afternoon sky. Inside the opulent but sterile command deck, Giovanni gripped the armrests of his obsidian chair, his knuckles white.

The monitors displayed the sprawling, familiar landscape—the perfect hunting ground for his objective. Giovanni planned to descend, to meet Silver himself, to finally face the consequence of his leadership and his failings as a father.

He pushed up from his chair, a resolve hardening in his eyes, but before his foot could fully settle on the deck plating, a shocking, blinding pain tore through him. It was a searing fire that started in his chest and branched out, wrapping around his ribs like sharp iron vines.

He gasped, stumbling backward, the strength leaching from his legs instantly. The high-ceilinged room spun, and he collapsed, catching himself on one knee as he thought, 'Not now. Not when the boy is so close.'

He recognized the sensation: the brutal physical backlash from his utilization of the Unown's power, compounded by the exhaustive manipulation of reality during his last, desperate stand. His body was protesting the demands of his ambition.

Sweat beaded on his brow. He couldn't move. His voice was a strained whisper, but the airship's internal comms amplified it swiftly, "Sird. Orm. I am indisposed. You will go in my stead. Do not fail me."

Within moments, two figures were moving toward the deployable pod bay. Sird, efficient and cold, and Orm, loyal and grim. A small, pressurized pod detached from the airship's belly, descending rapidly toward the ground.

Below, hidden among the trees, Silver watched the pod's descent alongside Yellow. Giovanni, kneeling painfully on the deck, watched the ensuing confrontation play out across the vast screens.

He saw Sird's icy precision and Orm's brutal force engaging the two young trainers, but his attention was fractured. The exhaustion was absolute, dragging his mind and body down into a deep, agonizing mire. He was merely waiting now, suspended between the promise of a reunion and the shadow of his failures.

*BEEEP*

*BEEEP*

It was during this desolate moment of waiting that the sensors screamed a warning, and three distinct, impossible signatures registered simultaneously. He lifted his gaze to the main viewport. They were approaching at breakneck speed: a streak of emerald fury flanked by an aura of pure psychic power.

Azure. Rayquaza. And Mewtwo.

Giovanni could only manage a slow, bitter smile and uttered, "Of course."

He remembered Seven Island, the desperate, brutal clash at the Trainer Tower. Despite having the advantage of the Unown's restorative powers, Giovanni had been pushed to the edge.

Azure, running purely on adrenaline and fierce devotion to his partners, had managed to neutralize Giovanni's strongest fighters. But in return, he managed to take out 4 of Azure's strongest Pokémon in the process—Pikachu, Scizor, Dragonite, and Arcanine—before succumbing to sheer exhaustion.

Yet, even in that moment, Giovanni knew victory had not been earned. He pushed off the floor, pain momentarily forgotten, replaced by a surge of pure, competitive fire.

He drew strength not from the airship's technology, but from the memory of Azure's tenacity. Azure, the one challenger who had taken him down not just once, but multiple times, forcing him to adapt, to innovate, to lose.

He straightened his back, rolling his shoulders. He murmured, watching the dots grow larger on the screen, "Impressive… You got through the M2 Bind, the remnants of R, and the Unown's chaos. And you found me despite my team currently recovering from our last dance."

A Trainer like Azure wouldn't be defeated by mere exhaustion or a structural barrier. Azure wasn't just skilled; he was defined by an almost terrifying resilience.

Giovanni decided, a cold, hard finality in his tone, "Before I see my son… I will have one last, true battle."

[Kanto Region, Team Rocket Airship – Battlefield]

*Zoooom*

Azure was a blur of motion strapped to Rayquaza's back, the wind whipping his unbound silver hair across his face. Beside them, Mewtwo cut through the atmosphere like a razor blade. Mewtwo projected telepathically, its tone sharp with caution, 'The airship is changing shape, Master.'

*CLANG*

The massive metallic structure below was responding to their approach. Panels retracted, sections separated, and within seconds, the top of the airship had flattened and opened, revealing a colossal, specifically designed expanse of reinforced metal—a formal Pokémon battlefield.

Azure's heart hammered a frantic rhythm against his ribs. Despite the exhilaration of riding the Sky High Pokémon, a deep, chilling tremor ran through him.

It was a familiar, primal instinct that had saved his life countless times. His body was shivering again as he murmured, "Deoxys is waiting."

Rayquaza descended, its roar echoing across the sky before landing decisively on the pristine battlefield. Azure immediately returned the Legendary Pokémon to the Master Ball, the deep indigo sphere resting heavily in his hand.

*Tmp*

The instant his shoes hit the metal deck, several thick, polished metal poles shot up around the circumference of the battlefield. They fired synchronized beams of brilliant purple light that stitched together, forming a solid, shimmering pyramid-shaped barrier around the entire combat zone.

There would be no retreat, no escape.

From the dead center of the field, the deck plating shifted, and a circular elevator platform rose smoothly. On it stood Giovanni, dressed in his traditional black turtleneck and trousers, looking recovered but drawn, and floating silently beside him, the silent, terrifying form of Deoxys.

Giovanni's voice was rich, cutting through the synthesized silence of the barrier as he said confidently, "Azure. Mewtwo. Welcome to the highest ground in Kanto. Tell me, what is it like, standing there?"

Azure tightened his stance, his gaze locked on Deoxys as he replied, "What are you talking about, Giovanni?"

Giovanni clarified, a hint of genuine respect in his voice as he eyed Azure, "Higher ground. You were the only one, Azure. The only one to defeat me in battle, not once, but repeatedly. You are a constant thorn, an absolute threat to anyone who seeks dominance over this world. You, who constantly refuse the ultimate title, stand above the Champions you dethrone."

Giovanni took a deep breath, his eyes gleaming with anticipation as he continued, "Today, I face you not as the leader of Team Rocket, nor as the defunct Viridian Gym Leader. I face you merely as a Trainer. A challenger."

*RSTL*

With a dramatic, decisive motion, Giovanni pulled off his signature white and red jacket, casting it on the deck. He declared, his voice ringing with challenge, "Azure Sky… The Uncrowned Champion. Face me."

Azure met his declaration with equal gravity. He felt the weight of his wins, his Hoenn League victory, all the trophies he had refused to claim, the titles he had walked away from to continue his journey.

He acknowledged the truth of Giovanni's statement with a silent nod as he uttered, "… Very well then. I'd never refuse a challenge from you, Giovanni…"

*RSTL*

He removed his own jacket and dropped it onto the metal deck. Giovanni noted, smiling fiercely as he stated the rules, "The greatest battles require the greatest stakes. This will be a one-on-one battle. Mewtwo, against my partner, Deoxys."

Mewtwo stepped forward, its eyes narrowed in concentration. Mewtwo broadcast telepathically, its voice echoing only in the minds of the trainers and the opposing Pokémon, 'Deoxys. I am Mewtwo. It is a pleasure to finally face the true form. The clumsy duplicates and their simplistic tactics at the Trainer Tower were merely annoying distractions. You, however, are a worthy opponent.'

Deoxys remained perfectly still, its crystalline core pulsing faintly. It offered no reply, conserving its energy and presence.

*Zoooom*

Mewtwo did not wait. It rushed forward, the speed of its approach distorting the air. It brought its signature metal spoon down in a powerful, psychic-enhanced strike.

*SWISH*

Deoxys's red tentacles snapped outward like whips, intercepting the blow with uncanny instantaneous speed…

*Clang*

The sound echoed sharply off the barrier. The initial engagement was furious. Mewtwo pressed the attack, combining physical strikes with bursts of raw psychic energy, trying to force Deoxys into an immediate reaction.

*SWOOOSH*

The battlefield became a blur of teleportation and kinetic impact. The fight quickly moved into the air, the two Legendary Pokémon rising high above the trainers, exchanging blindingly fast blows.

Mewtwo called out telepathically, its focus absolute but its connection to its partner unwavering, 'Master, I do not need your commands to fight, but know that you are free to give them. Guide me if you see an opening.'

*ZOOOM*

Mewtwo rushed in once more, attempting to grapple with Deoxys, driving power into a concentrated focus punch. But Deoxys was instantaneous.

*Swoosh*

In the fraction of a second before the punch could land, Deoxys shifted. Its form became sleek and aerodynamic—the Speed Forme. It ducked the blow and circled Mewtwo twice before the Psychic Pokémon could register the movement…

*Swooosh*

… Then, before Mewtwo could counter the speed, Deoxys's body swelled, its defense mechanisms manifesting. It shifted into its bulky Defense Forme, absorbing a follow-up Psychic blast with minimal effort.

Finally, as Mewtwo recoiled, Deoxys became sharp and aggressive, its arms transforming into wickedly barbed weapons—the Attack Forme. It unleashed a devastating counter-strike, a surge of concentrated dark energy that struck Mewtwo full force, sending the Psychic Pokémon plummeting down to the metal deck.

*SMASH*

Mewtwo hit the ground hard, skidding several meters, its breath knocked out as it spoke telepathically, 'So that's what Master was talking about…'

Giovanni called down, his tone conversational, yet laced with triumph as he watched Mewtwo struggle to rise, "Impressive, isn't it? You see, Azure, the influence of the Ruby and Sapphire's power has finally reached Viridian at full capacity. This allows Deoxys to change Formes at a quick pace, shifting its strategy in an instant. It is always the perfect counter to whatever you attempt."

Azure fixed his gaze on Giovanni, his expression unreadable, even as he helped Mewtwo rise telepathically. Giovanni's boast was technically true, but he failed to realize the context was entirely wrong.

Both Mewtwo and Azure understood the true mechanism at play. They knew that the immense atmospheric energy stirred up by the clash of Groudon and Kyogre, channeled through the Red and Blue Orbs, had empowered this specific Deoxys.

And they knew one other, critical fact: they possessed the Ruby and Sapphire. Azure had recovered them long ago.

A single command, a subtle psychic wave directed toward the Orbs stored safely in his pack, could neutralize this external energy, effectively disabling Deoxys's ability to change Formes with such unparalleled speed.

They did not. They had traveled too far, fought too many battles, to allow this clash to be anything less than absolute.

They wanted Deoxys at its absolute, terrifying best.

Mewtwo stood, shaking off the impact as it continued speaking to Azure, 'Master. A strategy is imperative. If I cannot predict its next form, I cannot construct a lasting attack. Every strategy is immediately countered.'

Azure looked up at the Legendary Pokémon, his mind racing through thousands of possibilities as he thought, 'Speed was useless. Defense was useless. Tactics were meaningless against instantaneous adaptation.'

Azure commanded calmly, his voice clear and ringing with conviction, "Then don't use strategy, Mewtwo. If adaptation is its strength, then overwhelming, undeniable power must be yours. You cannot out-think it. You must overpower it."

He pointed at the floating, alien form of Deoxys as he continued, "Aim for the core. Attack with the single strongest move in your arsenal. Hit the crystal in its chest and do not stop until it shatters!"

Mewtwo understood instantly. It didn't need a tactical setup; it needed a decisive, brute force solution.

*RMBL*

It closed its eyes, and the air around it began to vibrate violently. A high-pitched whine rose from the ground as the Psychic energy Mewtwo commanded began to gather. It was drawing from its own power, amplifying the devastating force.

*PEW*

Energy converged on its uplifted hand, focusing into a blinding, cobalt sphere—not merely a Shadow Ball or a Psychic, but a supernova of raw, concentrated force aimed at the one vital point of the alien creature.

Deoxys, sensing the unprecedented threat, began to shift, attempting to enter its Defense Forme, but the energy was gathering too quickly. Mewtwo's eyes snapped open, blazing with power.

With a roar that wasn't sound but sheer mental force, it fired the blast directly at the crystal in Deoxys's chest. Deoxys, still in its Attack Forme, merely brought its powerful, tentacle-like arms up, blocking the attack with ease.

*BOOOM*

The impact reverberated, but the alien Pokémon remained unfazed. Giovanni scoffed, a hint of disappointment in his tone, "A simple, brute-force attack? I expected more from the supposed Uncrowned Champion. No plan, Azure?"

He commanded Deoxys, "Go!"

*ZOOOOM*

Deoxys, still in Attack Forme, launched itself at Mewtwo, a flurry of rapid, powerful punches raining down. Mewtwo tried to counter, but Deoxys shifted to Defense Forme in a flash, its armored form deflecting Mewtwo's retaliatory strike, then instantly reverted to Attack Forme to land another series of blows.

*SMASH*

*SMASH*

Giovanni pressed curiously, watching the onslaught, "Why the chest, Azure? There must be a reason for such a direct, yet seemingly simple, target."

Azure's voice was calm, cutting through the din of battle as he explained, "That's not just a crystal, Giovanni. It's Deoxys's core. It's very heart. Damage it enough, and Deoxys stops moving."

Giovanni conceded, his expression remained skeptical, "An interesting theory…"

Mewtwo, absorbing Azure's words, surged forward, attempting to exploit the newly revealed target in mind. But Deoxys, anticipating, shifted to Speed Forme, blurring past Mewtwo in an instant.

*Woooosh*

Before Mewtwo could react, Deoxys had wrapped its elongated tentacles around its body, constricting it. Giovanni observed, watching Deoxys, Mewtwo uttered, "So, you correct me. The crystal is Deoxys's core. And now your Mewtwo is trapped."

Deoxys tightened its grip, Mewtwo struggling against the crushing force. Just as its psychic shield began to falter, a sudden, precise strike erupted from Mewtwo's own body.

*SHANK*

Not a blast, but a physical projection of psychic force, slender and sharp, like a spear made of pure mental energy, tipped with the distinct shape of Mewtwo's spoon. It shot outward, piercing Deoxys cleanly through the chest, directly impacting the radiant core.

*WOM*

A violent shudder went through Deoxys. It released Mewtwo, its tentacles flailing as it rapidly, almost erratically, cycled through its Formes – Attack, Defense, Speed – each form attempting to clench and protect the now ruptured core.

Giovanni exclaimed, his eyes widening, "A trick, then! Your statement of 'no plan' was merely a feint!"

Mewtwo's voice resonated, steady despite the recent constriction, 'You are mistaken, Giovanni. My master merely instructed me to hit Deoxys's core by any means possible. He did not specify how. My style is to trust my master implicitly, no matter the circumstances, and find a way.'

*Shiii*

It floated confidently, its psychic energy pulsing as Mewtwo continued, 'Deoxys cannot control itself now. Victory is mine.'

*SHIII*

But Deoxys was far from defeated. A brilliant aura pulsed from its damaged core, and with a surge of energy, it used Recover, the wound knitting itself together, the erratic Forme changes calming.

*ROOOOAR*

Then, with a roar of unbridled power, it unleashed a potent Psycho Boost, a devastating wave of psychic energy aimed directly at Mewtwo. Mewtwo braced itself, but Azure's command was already in its mind, 'Mewtwo, don't let it use Recover again! Hit it with everything!'

Mewtwo, its form glowing, didn't just counter. It revealed the true nature of its previous one blast attack…

*SHOOOM*

The initial projective strike had been merely the trigger. Now, from the sky above, several more spoon-shaped blasts of psychic energy rained down, each one a focused, piercing attack aimed at Deoxys's core.

Giovanni yelled, his voice laced with urgency, "Deoxys, Defense Forme!"

But it was too late.

*KERSMASH*

Deoxys, still reeling from the core strike, was unable to execute the swift transformation. It took the barrage of hits in its Normal Forme, the impacts echoing like thunder. Its crystalline form shimmered, cracks appearing along its surface, particularly around its now-exposed core.

With Deoxys too weak to change Formes, its movements sluggish, Mewtwo saw its chance. It brandished its spoon, its eyes burning with intensity, and rushed in for the finish.

Azure, however, felt a sudden, cold dread. Something was wrong as he yelled, his voice cutting through the wind, "Mewtwo, be careful!"

Mewtwo replied telepathically, confidently, 'No need, Master. I have figured out Forme Change's weakness!'

*Zoooom*

It continued its furious assault, a relentless volley of strikes. Deoxys, barely able to raise its weakened tentacles, blocked the attacks, but each blow pushed it further back, until it was slammed against the airship's perimeter wall.

Mewtwo, sensing the end, gathered its power for a final, decisive strike. Just as Mewtwo prepared to deliver the finishing blow, Azure's voice, sharper and more urgent than ever, pierced its concentration, "Mewtwo! Teleport! Now!"

*SWF*

The command was absolute, Azure's intent clear. Mewtwo, trusting its master implicitly, vanished in a flash of blue light.

*SHANK*

It reappeared a dozen feet away, just in time to avoid being impaled by two razor-sharp tentacles that shot out from where it had been moments before. Mewtwo's eyes widened as it thought, 'Those tentacles were Deoxys's Attack Forme. Yet, Deoxys was still visibly in its Normal Forme, leaning against the wall, weakened.'

Giovanni, a tired, knowing smirk on his face, finally spoke, "Tch. Too close, Azure. You saw through it."

He looked at Mewtwo as Deoxys revealed its trick, explaining to them, "Deoxys was utilizing a sophisticated aurora, a psychic illusion, to make itself appear to be in its Normal Forme. In actuality, it had shifted to its Attack Forme the entire time, waiting for your final, predictable strike."

He paused, a glint of the old Team Rocket leader in his eyes as he added, "And in that brief moment of deception, Deoxys managed to use Recover once more."

The alien Pokémon, still in its Attack Forme, its core now fully healed, unfolded from the wall. Its single eye-like structure glowed with renewed intensity.

Giovanni said boldly, his voice now tinged with genuine admiration, "Azure, Mewtwo… You are truly the strongest opponents I have ever faced."

His smile was grim, but filled with a new, dark resolve as he continued, "Therefore, I will grant you the honor of witnessing the strongest move in Deoxys's arsenal. Prepare yourselves for Psycho Boost."

*CRACKLE*

Deoxys, having fully recovered its strength, began to gather an immense amount of psychic energy. The air around it crackled, distorting with the sheer power it was accumulating. Its core pulsed violently, expanding with an ominous, purple glow. The airship itself seemed to shudder under the strain.

Azure's eyes widened, recognizing the tell-tale signs. He muttered, the name a whisper of dread, "Psycho Boost…"

The raw power emanating from Deoxys was staggering. There was no doubt this was the real thing, a finishing blow of unimaginable magnitude.

He knew Deoxys was stronger here, team-upped with Giovanni's formidable intellect and strategic prowess. He felt the weight of the moment, the sheer power of their opponent. But backing down?

That was not in Azure's nature. Not when Giovanni still stood before him, his ambitions unchecked, his threat to the region undeniable.

A glint of fierce determination entered Azure's eyes. He looked at Mewtwo, his expression softening into a knowing grin as he said calmly, "We can't back down, can we, Mewtwo? Not until we stop him."

He paused, a spark of mischief and fierce resolve in his gaze as he continued, "And I think it's about time we stop holding back, wouldn't you agree?"

Mewtwo, its form radiating heightened awareness, subtly nodded its head. The telepathic resonance between trainer and Pokémon was absolute.

It was time. Time to unleash everything.

Giovanni, despite his unwavering confidence in Deoxys, felt a sudden, inexplicable sense of unease. Azure's grin, Mewtwo's silent nod – it was too calm, too knowing. He had faced Azure enough times to recognize that look.

There was a trick. A hidden ace. Still, he had committed.

Giovanni roared, "Deoxys! Psycho Boost!"

*PEW*

With an ear-splitting shriek of raw energy, Deoxys unleashed its ultimate attack. A colossal beam of concentrated psychic power, vibrant purple and crackling with destructive force, erupted from its core, rocketing towards Mewtwo.

It was an attack designed to obliterate, to leave nothing but dust in its wake. But Mewtwo was ready.

As the Psycho Boost tore towards it, Mewtwo's eyes flared with an intense, inner light. With a surge of its own psychic will, it threw up a shimmering, hexagonal barrier. It telepathically projected, not just to Azure, but to Giovanni as well, its voice resonating with an almost defiant challenge, 'Protect!'

*CLANG*

*KRA-BOOOOOM*

The Psycho Boost slammed into the Protect barrier with the force of a supernova. The impact generated a blinding flash of light and a shockwave that rippled through the entire airship, making the pyramid barrier groan and shimmer precariously.

For a heart-stopping moment, it seemed the barrier would shatter. But Mewtwo's Protect held, absorbing the full brunt of the cataclysmic attack.

Then, through the telepathic link, Mewtwo's voice resonated, clearer and more powerful than before, a voice of pure, unbridled power, 'Giovanni. Azure. It is time. Time to unleash my full power.'

*SHIIII*

As the last vestiges of the Psycho Boost dissipated against the flickering Protect shield, Mewtwo's form began to glow. Not with a harsh, aggressive light, but with a serene, otherworldly rainbow aura that pulsed and expanded, encompassing its entire being. Its form started to shift, subtly at first, then more dramatically.

Muscles bulked, bone structure deepened, and its tail broadened. Its eyes, once sharp and focused, now held an ancient, almost primal wisdom, glowing with an inner intensity. Giovanni stared, his jaw slack, his perfect composure shattered.

Giovanni took an involuntary step back, his eyes wide with a shock so profound it stripped away his cool facade. He had never seen anything like it. Never conceived of such a transformation. He whispered, his voice laced with disbelief and a dawning, terrifying realization, "What… what is this? Mewtwo… can Mega… Evolution? Impossible! I never designed that capability!?!"

His eyes, wide with shock, scanned Mega Mewtwo X. It was a revelation that shook his understanding of even the most powerful Pokémon.

Azure stood firm, the rainbow light of Mega Evolution reflecting in his determined eyes. His jacket, discarded on the floor, seemed a lifetime away. Here, now, he was just a Trainer, backed by his partner, facing the ultimate challenge.

Azure said calmly, his voice ringing with authority, "The battle's not over, Giovanni. It's just begun."

The rainbow light flared one last time, then coalesced into a form far more formidable, far more imposing than before. Mega Mewtwo X.

Mewtwo X leveled its new, fierce gaze at Deoxys. The two titans, Mega Mewtwo X and Deoxys, locked eyes as a primal excitement, a glint of a smirk, flashed across Mewtwo's face. The true clash of the gods commenced. Then, they were gone.

*BOOOM*

They collided mid-air, a sonic boom ripping through the airship. Blows exchanged at speeds that defied human perception, phantom afterimages trailing their path.

They rocketed higher into the sky, their forms blurring, before grasping each other's wrists, locked in a brutal contest of strength. With a synchronized roar, both legends struck with Zen Headbutt, their psychic energy flaring.

*BOOOOM*

In the same moment, Mewtwo powered up with Bulk Up, its muscles visibly swelling with enhanced strength. Deoxys, not to be outdone, responded with Psych Up, instantly mirroring Mewtwo's stat boosts, an unsettling equalizing force.

*Woooosh*

Almost instantly afterwards, Mewtwo released its hold, spinning Deoxys around with terrifying force and tossing it a great distance. Before Deoxys could recover, Mewtwo summoned its iconic spoon, now larger and glowing with an ominous purple light.

*SHINNG*

*SHINNG*

It slashed, unleashing multiple Psybeams of raw psychic energy that arced through the sky towards its foe. Deoxys, however, was cunning.

*WOM*

It swiftly broke through the Psybeam assault, its form shifting subtly into its Attack Forme, and retaliated with a focused Dark Pulse.

*SWF*

Mewtwo, anticipating, dodged with a flicker of Teleport, reappearing closer, its form now shifting into Speed Forme. It lunged, a blade of pure psychic energy manifesting on its arm, attempting a Psycho Cut.

*Wooosh*

Deoxys, equally swift, teleported a distance away, avoiding the strike. Mewtwo bristled, forming a potent Aura Sphere in its hands, throwing it with pinpoint accuracy.

*SMACK*

Deoxys, now in its Normal Forme, met it with a sudden Knock Off, batting the orb away as if it were a mere pebble. Then, it surged forward, blazing in Speed Forme, closing the gap with an Aerial Ace.

*ZOOOOM*

*BOOOOOM*

The two legends met in another explosive clash. Deoxys, a streak of comet-like energy, slammed into Mewtwo's outstretched arm, the Aerial Ace, a fierce blow. As they grappled, Mewtwo's lips curled into a smirk.

*Swooosh*

With a silent command, it recalled the Aura Sphere it had just thrown. Deoxys, suddenly aware of the returning threat, barely managed to erect a Protect barrier in time.

*BOOM*

The Aura Sphere detonated against the shield, a blinding explosion that ripped through the air, sending both legendary Pokémon careening into the distance, a silent testament to the raw energy unleashed. A temporary silence descended, broken only by the groaning of the airship's superstructure…

*SHIII*

Then, a colossal wave of shimmering blue psychic energy erupted from the depths of the clouds, colliding with a significantly smaller, yet intensely focused, wave of purple. From the heart of the blue energy, Mewtwo emerged, its form once again transformed.

Gone was the imposing musculature of Mega Mewtwo X. In its place was a more slender, almost ethereal form, its head elongated, a long, flowing tail like a psychic ribbon trailing behind it. This was Mega Mewtwo Y, its eyes burning with pure, unadulterated psychic power.

Giovanni's voice was a ragged whisper, a man who thought he knew all the secrets of the world, suddenly finding himself blindsided, "Two forms?!"

The sheer versatility of Mewtwo was staggering. Deoxys, sensing the overwhelming power of this new Mega Evolution, shifted its strategy.

*SHIII*

Its crystalline body pulsed with an inner light, and it began to power up using Cosmic Power, attempting to bolster its defenses and equalize the vast power gap. Mewtwo, with a slight, almost taunting chuckle, corkscrewed towards its foe, mocked telepathically, 'Come on, Deoxys! Show me your full power!!!'

It raised a fist, causing Deoxys to flinch instinctively, preparing for a physical strike. But Mewtwo's fist opened, unleashing a massive, concentrated Psychic blast, a Psywave of pure mental energy intent on crushing its opponent.

*SHIII*

However, the blast, powerful as it was, seemed to have little effect. Deoxys emerged from the fading energy, its form now shifted into its incredibly resilient Defense Forme. It had simultaneously erected a Delta Shield, combining the impenetrable barriers of Light Screen and Reflect, rendering Mewtwo's attack largely nullified.

Mewtwo took notice, its intelligent eyes analyzing the technique as it thought, 'Could I, too, mimic such a defensive marvel?'

*Shiii*

With astonishing ease, it shimmered, flowing seamlessly back into its Mega Mewtwo X form, its mind already adapting and strategizing. Giovanni's eyes widened as he uttered, "It can switch forms like Deoxys as well!!"

*ZOOOOM*

Deoxys, in its Defense Forme, rushed in with blinding Extreme Speed, swiftly shifting into its Normal Forme mid-dash, following up with a brutal Mega Punch. The two legends became blurs of motion, attacking and dodging at blindingly swift speeds.

*BAM*

*SMASH*

*BASH*

*CRACK*

*BOOOOM*

Mewtwo responded with Power-Up Punch, each strike increasing its strength, until they both landed a simultaneous, earth-shattering punch to the face. The synchronized impact sent shockwaves through the air, throwing both combatants back, plummeting towards the reinforced floor of the battlefield.

*THUD*

They landed hard, kicking up dust and debris. Both were breathing heavily, their energy visibly depleted, but their resolve unwavering.

*Shiiii*

They began to channel their remaining energy, gathering vast amounts of psychic power for their respective greatest attacks. Deoxys, shifting instantly into its Attack Forme, unleashed another devastating Psycho Boost. Simultaneously, Mewtwo, once again in its Y Mega Form, gathered its reserves, launching a devastating Psystrike.

*KA-BOOOOOM*

The two colossal blasts collided with unthinkable force. The impact wasn't just an explosion; it was a tearing of reality…

*CRACK*

The barrier holding the battle in place, designed to withstand the might of legendary Pokémon, shattered into countless shards, showering down like glittering rain. The entire airship shuddered violently, alarms blaring as structural integrity was compromised.

Both Mewtwo and Deoxys were caught in the concussive force, sent careening through the fractured airship and out into the open sky, plummeting towards the distant Viridian Forest… but the sounds of fighting could be heard.

*BOOOM*

*BAM*

*SMASH*

*BASH*

*CRACK*

They exchanged a few more brutal blows amidst the scattering clouds, their forms flashing in and out of sight. In a desperate maneuver, Deoxys, now in its Normal Forme, managed to grab hold of Mewtwo's long, powerful X-form tail.

*Wooosh*

With a surge of alien strength, it spun Mewtwo around a couple of times, building immense momentum, before letting go and tossing the Psychic Pokémon away like a ragdoll. Mewtwo let out a guttural growl, a sound of pure frustration and renewed determination, "GRAOO!! (Why you…!!)"

*Drip*

Flipping gracefully into the sky, it gathered a tremendous amount of energy, its mind focusing, its body surging with power from Calm Mind…

*CRACKLE*

It solidified back into its Y Form, then unleashed a powerful Shadow Ball, a sphere of pure spectral energy, at the rapidly approaching Deoxys. But, like before, Deoxys powered through the attack, its alien resilience pushing it forward, and struck Mewtwo with a devastating Superpower move that caused yet another, even larger, explosion.

*BOOOOOM*

The two titans, battered and bruised, crashed back onto the shattered remains of the airship's deck, now a mangled wasteland of twisted metal and exposed wires. They landed not far from their bewildered trainers, their forms flickering, struggling to maintain their Mega and Forme shifts.

*SHIII*

Deoxys, still in its Normal Forme, fired a Psychic blast. Mewtwo, though weary, avoided the projectile with a swift sidestep and charged towards its foe.

*Wooosh*

It seemingly readied a powerful punch, its Mega Mewtwo X form flickering into existence, before instantly vanishing with Teleport.

*Swf*

It reappeared behind Deoxys, charging up what appeared to be a focused Dark Pulse, a finishing blow. Deoxys, caught completely by surprise at the swift turn of events, instinctively raised its arms in front of itself, preparing for the defensive block.

Giovanni, too, braced himself, a grim look of resignation on his face. But the attack was a fake, surprising Giovanni with the feint.

Mewtwo, relishing in its brief, silent laugh, capitalized on Deoxys's vulnerable moment. It didn't attack.

*Swf*

Instead, it moved with blinding speed, trapping Deoxys within a powerful psychic hold, then Teleported away from the crumbling airship entirely, reappearing high in the sky. There, with one last surge of its incredible power, Mega Mewtwo Y engulfed Deoxys in a massive, all-consuming Psychic attack.

*BOOOOOM*

The resulting explosion dwarfed all previous ones, a blinding flash of blue energy that rocked the very heavens. The concussive force blew both Azure and Giovanni off their feet, sending them sprawling amidst the debris of the battlefield.

As the blinding light slowly died down, a profound silence descended, shattered only by the distant crackle of disintegrating metal. Both Mewtwo and Deoxys, their forms still locked in their powered states, landed heavily back on the battered battlefield, each visibly on the verge of collapse.

*Thud*

Their energy was spent. They knew, with a shared, unspoken understanding, that they had no other option but to use their strongest attacks one final time.

*CRACKLE*

Mewtwo, now in its Y Mega Form, slowly raised a trembling hand, gathering the last vestiges of its power to create a swirling, pitch-black Shadow Ball…

*SHIII*

Deoxys, its crystalline body barely holding together in Attack Forme, began charging its final, desperate Psycho Boost.

*Woooosh*

With a primal cry of exertion, Mewtwo hurled the ghost-powered orb. It streaked across the battlefield, a dark stain against the twilight sky.

*PEW*

Deoxys unleashed an immensely powerful beam of crimson energy. The two attacks collided with a cataclysmic roar, but the Shadow Ball, forged from Mewtwo's ultimate reserves, was hardly impeded…

*SHINNG*

… It tore through the Psycho Boost, diminished but still highly potent, and rocketed towards Deoxys. It pierced through the legendary Pokémon's body, directly into its glowing core. Its eyes widened in shock.

*ZOOOOM*

Mewtwo, momentarily impacted by the lingering force of the Psycho Boost, stumbled, but quickly regained its balance. Seizing what seemed like a final, fleeting opening, it surged forward, switching into its X Form one last time, channeling every ounce of its strength into its ultimate attack: an empowered Mega Punch coated over with Psystrike.

*BOOOOOOM*

Mewtwo roared, its fist connecting with the already damaged Deoxys. The impact was absolute, the final blow. Both legendary Pokémon were engulfed in a subsequent, terrifying explosion that ripped through the very fabric of the airship, sending Azure and Giovanni flying once more.

*Crack*

During the explosion, Deoxys's Poké Ball was cracked in the process. As the blinding light died down, a hushed silence fell...

The air was thick with smoke and the tang of ozone…

*Cling*

… A lone, crimson drop, like a tear of crystallized energy, plopped onto the shattered battlefield floor. The core of Deoxys fell on the floor.

Mewtwo, beaten but still breathing, slowly reverted to its normal form, its body trembling with exhaustion. It looked up, its gaze drawn to an iridescent core that lay on the ground before it. It was Deoxys's core, its entire physical body vaporized by the sheer force of the final attacks, leaving only the source of its consciousness behind.

Mewtwo offered a faint, almost imperceptible smirk. It knew.

Deoxys wasn't truly gone, merely entering a profound state of hibernation, its essence retreating to regenerate. Mewtwo telepathically voiced, its power depleted but its spirit invigorated, 'Thank you… Thank you for an epic bout, for meeting another Pokémon as strong as you.'

Its legs finally gave out. With a weary sigh, Mewtwo sank to one knee, its form still radiating residual power, settling beside Azure, who was slowly pushing himself up, his eyes fixed on his valiant partner as Mewtwo collected the core, passing it to Azure's hands as he safely stored it in his [Sub-Space].

The airship, a testament to the battle's ferocity, groaned its last, slowly descending towards the distant, accepting embrace of Viridian Forest. The Uncrowned Champion and his legendary partner had faced their greatest challenge and emerged, not entirely victorious, but utterly triumphant in battle.
