Mewtwo, who is newborn, opens his eyes in a laboratory,
finding a dozen people in white clothes. They are scientists, who have given a birth to
him, by genetically processing cells of Mew, the rarest Pokemon on the earth, to create the strongest Pokemon, able to speak a human language. Mewtwo's birth is
not natural, but artificial. He recognizes that, and is confused, and destroys the
laboratory. Giovanni, the boss of the Rocket gang, takes him and makes him help them with
capturing Pokemon. The mystery of his life is always in his mind, and he destroys the base
of the gang, too, to be alone.
Overlooking the sea in a grassland on a cliff, Ash waits
Brock's stew ready at a table. Misty helps Brock. Pikachu finds Togepi totter to the edge
of the cliff, and panicked, rushes to help him. Togepi stops an inch from the edge, while
Pikachu drops from it. The cliff is not deep at the side, to Pikachu's relief. Togepi
chuckles to see him crawl up. A man challenges Ash. Ash cheers up, fights him to send
Bulbasaur, Squirtle and Pikachu, and wins. Then a invitation card he receives, the message
told by a beautiful woman in holography. The sender is unknown, who is just introduced by
her the strongest Pokemon trainer, and is to have a Pokemon league in the Pokemon castle
in New Island. Ash decides to accept the invitation.
A storm outrages waves of the sea, so that it is impossible
to launch a ship, as his party arrives at a port. They learn that there are many other
trainers who were invited by the stranger, and that a female doctor of a Pokemon center is
missing. Trainers try the raged see, with the help of their Pokemon that can move in the
water or fly. Anyone of Ash's party doesn't own those types of Pokemon, and they don't
know what to do. But a boat appears, and the two sailors offer a ride. Relieved, Ash
accepts it. (He doesn't note Meowth at the head of the boat.) Ash is in high sprits in the
boat, while Pikachu is scared of pitching. As a huge wave assaults it, the helmets which
the sailors wore low over their eyes were swept away, revealing their faces. They are the
couple of the Rocket gang, Jesse and James. Ash is astonished. At that time another wave
comes, and they are all thrown out of the boat into water. Misty sends Stermie, while Ash
Squirtle, and Brock and his friends hug either of them, letting themselves totally in the
stream. Then they finally reach the New Island they were invited to. So does the gang a
moment later.
Only three trainers they find there were; Sweet, Sorao, and
Umio. The woman who appeared in the invitation card tells them to send their Pokemon from
balls, and they obey her. They are astonished when the host appears; he is Mewtwo, the
Pokemon who is unknown to them yet. It is out of question that a Pokemon is a trainer,
which outrages trainers there. The woman's condition suddenly changes, and she collapses.
Brock raises her in his arms, finding her a female doctor who they learned is missing.
Trainers send some of their Pokemon to fight Mewtwo, but he
beats them easily. Then he takes the trainers and Pokemon to a league field he made.
The gang steals into the building in the castle, and happans
to enter a laboratory. They find many huge tube there; some of them have a Pokemon. As
they wonder what is done there, Meowth is captured by a belt conveyer. He struggles to
escape, while magic arms pulls his three hair out. Meowth manages to escape, seeing the
computer beside the conveyer starts to work, and a copy of his is formed in a tube.
Mewtwo, highly inteligent, studies there and successfully creats copies of Pokemon, that
are stronger than the original. And they are not just copies; They have lives. Venusaur,
Charizard, and Blastoise come out of tubes, then go to the league field, called by Mewtwo
by telepathy.
Mewtwo knows that Sorao owns Venusaur, Sweet Blastoise, and
Ash Charizard. He is proving copies are superior to the originals. It is his revenge for
human beings who have given a birth to him, making use of him. And copies are strong. They
conquers originals easily, disappointing the invited trainers. Mewtwo's revenge doesn't
finish. Weird balls he made flies across the field, each aiming at original Pokemon there.
Mewtwo's balls capture them one after another, now leaving Pikachu. A dozen balls are sent
to him. He runs, sometimes shooting an electric beam. Ash is irreated to be near him to
help him. Finally, Pikachu is captured by a ball. Panicked, he runs after it which flies
away.
In the laboratory the gang is, Mewtwo's balls which includes
the trainers' Pokemon are carried on the belt conveyer. As magic hand takes one, the
computer analyzes the gene, and creats the copy. Pikachu's ball arrives, and Ash follows.
Those hands are stretching toward it Ash seizes it tight
in both his hands, as the hands reach it, too. Ash pulls, with all his might, and some
magic hands grabbed him, too. Ash gives another strong pull. Magic hands which on the ball
and him are torn, sparking. The computer also breaks, and Mewtwo's balls spits Pokemon
out. Pikachu is saved, too, and Ash hugs him tight in his arms. Copies are summoned by
Mewtwo and go to the league field. Ash and Pikachu follow them with originals. Then they
see a small, white Pokemon there. It was Mew. Mewtwo shakes his whole body with mixed
feelings, dread and delight that he would fight his original to prove HE is superior. As
they fight, Pokemon also battle with their copies hand-to-hand. The doctor says sadly,
watching them fight, "They are copies, which have been created artificially, yet have
lives, which are valuable equal to originals'." Pikachu's copy appears, too. He
glares at original Pikachu, and beats him hard. Pikachu doesn't resist, is hit by the
copy's blow, and thrown away.
Pokemon, both originals and copies, fight, collapse, and
fight... Only Pikachu doesn't fight, though harshly beated by his copy. The copy shouts at him, "pika, pikachu! (Fight me!)" Pikachu
shakes his head, refusing to counter. Tears well up to the copy's eyes, but he cannot stop
himself while Mew fights Mewtwo. Crying, the copy continues to beat Pikachu. Finally the
copy is exhausted and collapses. Pikachu takes to hold him tenderly.
Ash cannot stand to see them battle any longer. He dashes toward the spot Mew and Mewtwo fight, crying, "Don't! Don't fight any longer!"
Two Pokemon shoot sparks then, and they hit Ash. Screaming, he collapses to the ground.
Pokemon, including Mew and Mewtwo, freeze and just watch him. "Pikapi!" Pikachu
goes close to him, looking into his face. His body starts to stiff, and got rocky in a
moment right before Pikachu's eyes. Pikachu wonders at first what is going on, sees his
friend doesn't move, and shoot an electric beam at him, as he does instictively for
fainted creatures. But Ash is still. Pikachu tries once more, then over and over. While he
is too tired to shoot a beam anymore, Ash doesn't recover. Tears well up to Pikachu's
eyes, roll down his cheeks, and drop to the ground, quickly filtered into the soil. Other
original and copy Pokemon begin to weep. Their tears wet the ground, and are conveyed to
Ash through the soil. His body softens slowly, and he recovers finally. Pikachu hugs him,
and Ash hugs back. Mewtwo calls copy Pokemon by telepathy, and they floats up. He can now believe in his life, which is
valuable, and is leaving to look for the place they can live. Ash, Pikachu, their party
and other people and Pokemon see them flying away, now feeling for them.
When Ash is aware, he is at the port with his friends. Other
trainers are there, too. Now one remembers what happened in the island. The storm is over
a moment later, and the sea recovers the peace, its surface brightening in the sunlight.
