Mewtwo feels his body being torn apart then pieced back together bit by bit. He has teleported before, but never like this. There is pain here. A deep and heavy pain. Once the feeling fades away, Mewtwo looks around and notices his new surroundings. He is definitely not in the Hall of Origin anymore. There is a contrast to this place so definitive that it almost looks like a dream.
From Mewtwo's point of view, the left half of this new world is filled entirely with light and color. Warm and pleasant sunlight shines among the trees that bear fruit that sparkle like gems. The grass is such a brilliant shade of green, it looks as if it is made of emerald. However, the right side of the world is the complete opposite. The world is cold and lightless, yet Mewtwo can still see the outlines of the dead trees. The ground is made up of earth and ash and dust and the sky is a pale gray. On both sides of the world, there is silence.
Where am I? Mewtwo wonders.
A voice is heard. "You are in the World in Between."
Mewtwo turns to his left where the world is warm and sees a beautiful creature walking toward him. It is a stag, tall and proud. Most of its lower body is covered in black fur, but its upper body is a deep blue. On its head are eight antlers with gems of every color woven into them. It exudes a gentle aura.
"The world between what?" Mewtwo asks.
"The World in Between everything," another voice answers.
This time, Mewtwo turns to his right, looking into the cold world. At first he sees nothing, but then makes out the form of a massive eagle perched on the branches of a dead tree. It is a terrifying sight. It is covered in feathers the color of freshly spilt blood. Black markings adorn the center of its wings and body and scythe-like claws are seen on its wings and tail. This one gives off a sinister aura.
"This is the place where the choice is made," the eagle continues.
"What choice?" Mewtwo asks the eagle.
"The final choice."
The eagle looks at Mewtwo with hungry eyes. It has been so long since it last ate an Ageless…
"I know who you are and you do not frighten me!" Mewtwo shouts. In his hands, a sphere of energy starts to form. He will fight these pokemon if necessary.
"Oh, look." The eagle laughs. "The kitten wants to play. But you cannot stand against us, kitten. We are eternity."
Mewtwo knows that the eagle is right. He can sense the countless years in these two pokemon. To them, even his great power is nothing.
"Young one, be calm," the stag says with its soothing voice. "We mean you no harm."
Mewtwo's Aura Sphere fades away, but he does not let his guard down.
"Why am I here?" Mewtwo demands.
"You are here because the choice is being made." The stag answers. "The Ageless are debating on whether you will live or die."
"However, in the end, it is all the same to us." The eagle says next. "Eventually, everything dies."
Mewtwo feels a bit unnerved by this statement so he decides to change the subject.
"If the Ageless are debating, then why are you here? Should you not be in the Hall of Origin, as well?"
"I thought it would be obvious, young one," the stag begins. "If the choice is between life and death, then we have already made our choice."
"But you have a choice in this as well, kitten," the eagle tells him. "If you want to end it all, just step over to my side. It will be painless."
Even in the darkness, Mewtwo can tell that the eagle is wearing a malevolent grin. It is hungry…
"I will not give myself over to you. My time has not yet come." Mewtwo answers.
"You never know, kitten. As we speak, the Ageless might have made the decision to kill you. And I promise you, that will not be painless."
Mewtwo wonders about that. Will the other legendary pokemon really put him to death? He knows that he has made enemies among them. Some of them still wear the scars that Mewtwo inflicted upon them. However, most of them he has not even met.
And Mew. He cannot stop thinking about her. Mewtwo was created to be merciless, but even humanity's science could not completely shut his heart. He loves Mew. She is all he has left. He thinks about his mother and the thought gives him hope.
"I will live" Mewtwo declares.
And at that time, the World in Between begins to fade away.
"The choice has been made, young one." The stag says. "Live your life."
"But don't think you've seen the last of us." The eagle says in a voice barely louder than a whisper. "Remember. Eventually, everything dies."
