You must never give a Legendary Pokémon time.
Having Mewtwo at his side, Logan possessed more firsthand experience in commanding a Legendary than anyone present. Because of that, he understood better than anyone:
Never drag a battle against a Legendary into a prolonged war of attrition.
End it fast.
Overwhelm it.
Crush it with your strongest force before it stabilizes.
Aerodactyl.
Gyarados.
Charizard.
Two heavily injured Dragonair.
And Zekrom beneath Lance.
Except for the completely incapacitated Dragonite, Lance gathered every dragon he had into a final defensive formation, clashing against Giovanni's Ground-type army.
One side ruled the sky.
The other commanded the earth.
Cerise Island, already teetering on collapse, trembled once more beneath cataclysmic power.
Though vast like a miniature continent, the ancient legendary island had already endured the devastating clash between Lance and Logan.
Now, with Giovanni and Lance tearing into each other—
Its very foundation began to quake.
The once-raging volcano had been forcibly reduced to a dead crater by Logan and Lance's earlier war.
Now the mountain ranges resembled Mordor after destruction—
Hard stone crumbling like flour into dust.
Towering peaks visibly shrinking before the eye.
After his battle with Logan, Lance's Pokémon were gravely injured and exhausted.
From the outset against Giovanni, he was already on the back foot.
He gathered his dragons tightly into a defensive sphere, minimizing exposure.
Giovanni, meanwhile, unleashed relentless assaults from every angle, ordering his Ground-types to batter down Lance's already fractured defenses.
And Beedrill—
Just as it once had against Mewtwo in Saffron—
Pinned Zekrom mercilessly.
The Dragon of Ideals was now covered in wounds.
Even without intervening, Logan doubted Lance could reverse this.
But to avoid unforeseen variables—
He would personally end it.
Like Lance, Logan gathered his own forces.
Excluding the resting Mega Garchomp—
Mewtwo.
Latias.
Dragonair.
Sylveon.
These were his visible assets.
Though fewer in number—
Each rivaled Lance's in quality.
Each was Elite Four Commander tier.
Some even superior.
If an MVP were to be awarded—
It would undoubtedly belong to Garchomp.
Nearly single-handedly defeating Lance.
Eliminating the mutated Dragonite.
Holding Zekrom at bay.
In this moment—
There was no debate.
Logan's Garchomp was the strongest Garchomp in the world.
"Latias, be ready to strike when he falters."
After Lance recalled Aerodactyl and Charizard, Latias returned to Logan's side, awaiting orders.
"Mewtwo… it's your turn."
"End this in one strike."
Mewtwo nodded calmly.
Unlike the others, it appeared relaxed.
Its long tail swayed lightly.
Its mood—almost pleased.
"I've begun to understand what the Mega Stone truly is," Logan murmured.
"When Garchomp Mega Evolved, I sensed something."
"Now, Mewtwo—prove it."
"The researchers couldn't find the source of Mega Evolution's power."
"But we will."
[Are you ready, Logan?]
"Completely."
"I've already sensed it."
"The force that triggered Garchomp's Mega Evolution—"
"Comes from an unknown Pokémon in an unknown space."
"Mewtwo, merge your consciousness with mine."
"We don't need a Mega Stone."
"Together, we will seize that power ourselves."
Logan's eyes widened.
He raised his right hand.
The Keystone on his finger glowed.
He now understood:
Compared to the Mega Stones held by Pokémon—
The Keystone was far more important.
The Mega Stone was merely a conduit.
A channel connecting to a mysterious space.
The Keystone—
Was the key.
Once Mega Evolution concluded, the Mega Stone self-destructed.
But the borrowed power remained within the Pokémon.
The strong could retain it.
The weak—
Would be destroyed by backlash.
This explained why some records spoke of Pokémon Mega Evolving in moments of desperation—
Only to die once battle ended.
Thus—
Even without a Mega Stone—
As long as one possessed the Keystone—
In theory, one could replicate the connection.
That was what Logan and Mewtwo would prove.
Their consciousness merged completely.
And Logan's perception of the world changed.
He no longer saw through human eyes—
But through psychic sight.
Not like bat sonar—
Something far more profound.
A 360-degree, omnidirectional awareness.
Every object's shape, color, density, magnetic field—
All laid bare.
This was Mewtwo's world.
The world as seen by the strongest psychic being alive.
Even most Psychic-types perceived reality this way.
But Logan could not sustain it long.
The human brain could not process such data.
If not for the compatibility of Mewtwo's genetic cells within him—
He would have suffered immediate brain death.
Focusing his will—
He directed Mewtwo's psychic force into the Keystone.
He recalled the sensation from Garchomp's Mega Evolution.
Calculating the properties of an unknown dimension was impossible for a human mind—
But effortless for Mewtwo.
And then—
He saw it.
A space beyond description.
Colorless.
Formless.
Yet undeniable.
He had never been there.
But he knew.
The place recorded in ancient texts—
Never witnessed.
Never reached.
The origin of all things.
The Beginning.
The Hall of Origin.
And within it—
A presence writhed.
Agonized.
Raged.
Enraged at the theft of its power.
"—Arceus!!"
Logan gasped the name instinctively.
The Creator.
Of course.
Mega Evolution's power was not rootless.
Like all Pokémon—
It originated from Arceus.
And the fury Logan sensed revealed something deeper—
This was no ordinary energy.
It was primordial.
Creative.
The power that shaped the world itself.
Yet—
The theft was not caused by Mewtwo's psychic power.
Even Mewtwo could not steal from Arceus.
Psychic force merely opened the gate.
What truly stole the power—
Was emotion.
Bond.
The intangible will between human and Pokémon.
That was why researchers insisted on deep bonds.
Only true connection could "steal" divine power.
Seasons seemed to shift in an instant.
As the connection closed—
Logan felt Arceus weaken slightly.
As if a fragment had been torn away.
Reality snapped back.
To Cerise Island.
Though the Hall of Origin felt eternal—
In reality, only an instant had passed.
And in that instant—
An indescribable power descended upon Mewtwo.
Logan prepared to command its activation—
But paused.
Mega Evolution branched.
Two paths.
One—enhance the body.
One—enhance the mind.
Though the forms could theoretically shift—
Logan did not hesitate.
He chose.
The path of psychic supremacy.
He did not know what the form should be called—
Yet instinct told him.
——Mega Mewtwo Y.
The gods have been robbed.
The bond has stolen creation.
And Mega Mewtwo Y—
Is born.
