Elf: Start with small diamonds, then mutate into Diancie!

That was a figure that most of the legendary figures present, who participated in that battle to protect the world, did not want to recall.

"That is the army of dark Pokémon belonging to the dark matter."

Raising her hand, Calyrex unleashed "Star Shatter" upon Dark Mewtwo X's body, tightening the reins and speaking with a grave expression.

Reshiram's emotions were fluctuating wildly. It knew that on the other side of the passage was its former world.

"...It seems that the time has come to carry on the legacy of my dearest friend, the man who is half of me."

Zygard stopped releasing the "Core Punisher," his expression calm yet resolute.

Once upon a time, there existed two individuals with the Zygarde Core in this world.

One represents emotion, the other represents reason.

The Sensual Core, in the great war tens of thousands of years ago, sacrificed itself to divide countless Zygarde cells, sealing off the passage for the invasion of the dark matter army from the spirit world, thus buying extremely precious time for the descent of the creator god Arceus.

Finally, as the core of reason, it inherited part of the origin of its half-body and became what it is today.

"I'm sorry... Carlos, it seems I can't keep my promise to you."

As Zygard gazed at the distant sky, the girl in the underground shelter felt the same way. She looked up at the trembling ceiling and felt as if something important was missing from her heart.

After glancing at it from afar, Zygarde withdrew its gaze. It was not swayed by emotion to make a decision, simply because it represented the core of reason.

At this moment, Zygarde's entire body was filled with a deep green light.

That was a harbinger of "disintegration," and also a choice Zygarde made to prevent the arrival of dark matter as much as possible.

Countless Zygarde cells transformed into deep green meteors, streaking across the lightless night sky obscured by Necrozma: Dawnwing, before attaching themselves to the dark spatial vortex, using their physical bodies to prevent the vortex from expanding further.

Forced to kneel on one knee by Dark Kyurem, Dark Mewtwo X, whose body was covered in wounds, looked up and glanced at that spot with a strange expression.

After a moment, it whispered, "Meaningless actions, pointless sacrifices."

"But that was Zigeld's choice, and the sacrifice was by no means meaningless."

Mega Mewtwo Y, transformed into its Y form, quietly appeared beside Dark Mewtwo X, and the energy belonging to "Psychic Break" was frantically gathering.

For some reason, Dark Mewtwo X was quite calm at this moment, just as Mega Mewtwo Y was wondering if its verbal attacks were no longer effective.

Dark Mewtwo X suddenly stopped releasing its psychic energy and said in a low voice, "Stop."

Super Mewtwo Y & Dark Kyurem: ?

After glancing at them, Dark Mewtwo X calmly said, "That can only temporarily slow down the invasion of dark matter, but cannot completely solve the problem."

Hearing this, SuperDreamY frowned deeply. "What do you mean? What are you planning...?"

That being said, it, along with Dark Kyurem and other legends, stopped focusing their attacks on Dark Mewtwo X, which was already nearing its limit.

Dark Mewtwo X calmly stood up, glanced at Lugia, Diancie, and Xerneas who were fighting Solgaleo, and then at Giovanni's figure standing with his hands behind his back in the distance. A mysterious expression appeared in his eyes.

You're right.

"Perhaps... if I had persevered a little longer then, and trusted my 'partners' a little more, everything would have been completely different."

"My hands will not be stained with the blood of sin."

Despite the excruciating pain within his body that felt like it was shattering his brain, Dark Mewtwo X, blood trickling from the corner of his mouth, looked relieved.

"And now, I want to try to rebel again."

"This ominous body, filled with negative energy, may have existed just for this moment."

------------

Chapter 1563 As expected, I have indeed made a comeback.

When did I lose the courage to make a comeback?

Even Dark Mewtwo couldn't give itself a definite answer to this question.

Initially, it was no different from the life trajectory of another version of myself.

She was cloned by Team Rocket scientists, met Ai and Charmander in her dream, and then watched them disappear.

But that heart-wrenching pain gradually became blurred with the passage of time.

The story revolves around a complete awakening, the destruction of the research institute on the new island, and the eventual counterattack against humanity.

All the experiences were very similar to those of another version of myself.

But at another crucial juncture, everything went awry, and fate took a different turn.

Trapped on Clear Cliff, it watched helplessly as cloned Pokémon and those naive yet admirable boys and girls were brutally murdered by Team Rocket.

Ultimately, it accepted its fate of being unable to be redeemed, its indomitable spirit crumbled, and it became Team Rocket's... Giovanni's "weapon" in spirit.

What followed was a period filled with blood and sin.

On one hand, the scientists gathered by Sakaki constantly tightened the mental shackles on themselves, making it impossible for them to find a way to break through.

On the other hand, the armor that was once used to suppress power has been continuously modified and iterated, unleashing its own power and destructive power to the fullest extent.

At the same time, it also became a sharp weapon for resolving various troubles when the Rockets' power was rapidly expanding.

Even the Elite Four or the Champions were no match for its power. Its overwhelming psychic abilities overwhelmed them one by one, and in no time at all, the entire Kanto and Johto regions had fallen under Team Rocket's covert control.

Based on this, Team Rocket continued to expand outwards, aggressively plundering the resources of evil organizations in other regions.

Those who disobey will die, those who obey will live.

In the days that followed, to be honest, Mewtwo's own memories were also quite hazy.

It lived like a zombie, except when it went out to suppress rebellions in Team Rocket's territory, it would return to the "Hangar" and stand there like a machine, its body covered with tubes to deliver nutrition and necessary energy, watching expressionlessly as Team Rocket's repair engineers performed regular maintenance on its armor.

Mewtwo, whose hands were stained with countless drops of blood and whose shoulders bore the weight of countless lives, knew very well this.

One's own surrender is the key that opens Pandora's box.

Mewtwo doesn't quite remember exactly how long it took for Team Rocket to completely dominate the world.

All it knew was that Sakaki's appearance, which showed increasing satisfaction in his eyes, had been completely fixed since the Carlos region conquest war.

During this period, Team Rocket acquired countless rare Pokémon and Pokémon with special abilities, including even the legendary Pokémon.

Such suppression activities are often carried out by Mewtwo alone.

However, Giovanni's actions were quite restrained; he did not touch any other legendary spirits that held a special place in the world.

At least, he wouldn't act like that until he had trained Mewtwo to the point where he could actually fight it.

Ultimately, wars, conquests, and changes in power between humans will not affect the normal functioning of the world.

What Giovanni wanted was absolute domination, not destruction.

—Until one day, something called the "Ultimate Hole" appeared in front of Sakaki.

Using the Ultra Hole, Giovanni, along with several other leaders of evil organizations who had also achieved their ambitions in their own worlds, joined forces to form Team Rainbow Rocket, intending to conquer other parallel worlds across time and space.

However, Team Rainbow Rocket suffered a crushing defeat in their first target world.

The ten-year-old boy, dressed in a cool short-sleeved shirt and shorts, was accompanied by the creator of the ultimate world, the Radiant God Necrozma.

In that battle, the other members carrying legendary spirits were defeated one after another, falling into the Ultimate Cave and disappearing without a trace.

Giovanni and Mewtwo themselves were unable to resist the power that surpassed all legends and were forced to retreat into the Ultra Cave.

However, perhaps due to the influence of the power of Ultimate Necrozma, the destination, which should have been the Ultimate Hole of the original world, was deflected to a world completely different from what Giovanni and Mewtwo knew.

The history, countries, and alliances of this world are completely different.

More importantly, the legendary spirits of this world have a more concrete concept of power.

Having learned of this fact, Giovanni, who had just suffered a humiliating defeat, immediately decided to find a way to enhance Mewtwo's power in this new world.

As for Mewtwo's own wishes?

It's just a puppet.

In Giovanni's view, the mental shackles that had been reinforced over the years had rendered Mewtwo incapable of rebelling.

Mewtwo has probably long forgotten its past emotions and memories, and has become a proper weapon.

Instead of making a grand show of seizing control of the world, Giovanni began using Mewtwo's psychic abilities to brainwash people and build an organization that would gather intelligence and plunder wealth for him.

Then, at the highest peak of this world, they found the Creation Star, a sub-core of dark matter, lurking within the World Tree's secret realm, and made an agreement to assist it in exchange for the source of negative energy.

What followed was a long period of incubation, during which the effects of negative energy were tested using legendary Pokémon as the primary subjects. Cresselia and Darkrai, who were captured, were the victims.

It wasn't until, under Giovanni's orders, that Mewtwo, returning to his old research, found a way to eliminate the backdoor within the negative energy.

It successfully transformed into Dark Mewtwo, gaining power comparable to, or even surpassing, that of Ultimate Necrozma—power that transcends legends.

—Then, time came to the present.

Even after saying those words, Dark Mewtwo X still didn't quite grasp the reality of his impending defeat.

It's as if that special Diancie possesses an aura that is naturally able to suppress negative energy.

These are the legendary elves who, at the call of a human, fought to the death against themselves without fear.

And finally, the Source of the Primordial Crystal makes its appearance, sacrificing its own life to turn the tide.

The accumulation of various factors has somehow created a force powerful enough to overcome oneself.

But for Dark Mewtwo X, the effects of all this defeat were as vague as if he were in a dream.

It had long been numb to battle, and this battle had nothing to do with its own will.

It was merely a weapon, faithfully carrying out the orders given by Sakaki.

If we were to pinpoint the entity that had the greatest impact on it throughout the entire battle, it would undoubtedly be that other self, like a reflection in a mirror.

What a joke... What do you know about me? Have you ever experienced my pain? What gives you the right to condemn me based on your worldview?

Can you guarantee that you won't make the same choice as me if you were in the same situation?

During the battle, Dark Mewtwo X's own emotional fluctuations were almost entirely caused by Mewtwo.

It's as if they're trying to prove themselves, or perhaps they're unwilling to admit that they made the wrong choice.

Dark Mewtwo X focused almost entirely on attacking Mewtwo during the battle.

But just as Mewtwo said, even though it was powerless, it had partners to share the burden, and the combined power completely overwhelmed Dark Mewtwo X.
