Scientist Dr. Fuji is hired by Giovanni, leader of Team Rocket, to utilize his expertise in cloning in order to create a living weapon based on an eyelash from legendary Pokémon Mew. Soon after the weapon is created, it gains sentience and is named Mewtwo.

Several years later, Mewtwo has fully awakened from a long slumber in a laboratory on New Island, and learns of his origin as Mew's clone from Dr. Fuji. Infuriated that Fuji and his colleagues see him as nothing more than an experiment, he unleashes his psychic powers and destroys the laboratory, killing Fuji and the rest of the scientists. Giovanni, witnessing the carnage afar, approaches and convinces Mewtwo to work with him to hone his powers. However, after Mewtwo learns of his purpose to be a weapon for Giovanni's benefit, he escapes back to New Island where he plots his revenge against humanity.

After Mewtwo rebuilds the laboratory and establishes a base there, he invites several trainers with hologram messages to battle the world's greatest Pokémon trainer at New Island. Ash, Misty, and Brock receive a message and accept the invitation, but when they arrive at the port city, Old Shore Wharf, Mewtwo creates a storm, causing the boats on the wharf to be closed off for safety. As a result, Ash's group are picked up by Team Rocketdisguised as captains on a Lapras-shaped sailboat. After the storm sinks their vessel in the middle of the ocean, Ash and his friends use their Pokémon instead to reach New Island.

Escorted into the island's palace by the woman who appeared on the hologram, Ash and the other trainers who were able to reach the island encounter Mewtwo. The woman is revealed to be a brainwashed Nurse Joy after she is released from Mewtwo's mind control. Mewtwo challenges the trainers using cloned Pokémon. Meanwhile, Team Rocket also reaches New Island and explores its inner sanctum with a Mew innocuously following them. After Mewtwo's clones effortlessly defeat the challengers' Pokémon, he confiscates them and expands his clone army. Ash chases after his captured Pikachu down the cloning lab, where Team Rocket's Meowth is also cloned. Ash destroys the cloning machine, frees the captured Pokémon, and leads them to confront Mewtwo and his clones. Mew then reveals itself and Mewtwo challenges it in order to prove his superiority.

All of the Pokémon originals battle their clones save for a defiant Pikachu and Meowth, who makes peace with his own clone after realizing the senselessness of their fighting. Horrified at the pain and anguish felt on both sides of the battle, Ash puts himself in between a psychic blast caused by Mewtwo and Mew's fighting, leading to Ash to become stone. Pikachu tries to revive Ash with its electricity but fails. However, the tears of the Pokémon are able to heal and revive Ash. Moved by Ash's sacrifice, Mewtwo realizes that he should not have to be judged by his origins but rather his choices in life. Departing with Mew and the clones, Mewtwo turns back time to just before the trainers leave Old Shore Wharf, and erases everyone's memories of the event.

Back in Old Shore Wharf, the now-restored Nurse Joy has returned to reopen the Pokémon Center to shelter the trainers. The storm outside clears up, Ash spots Mew flying through the clouds and tells his friends of how he saw another legendary Pokémon the day he left Pallet Town. Meanwhile, Team Rocket find themselves stranded on New Island but enjoy their time there.

After the credits, a brief scene shows Mewtwo, Mew, and the clones flying towards Mount Quena.

Tim Goodman gave up his dream of being a Pokémon trainer following the death of his mother and his estrangement from his father Harry, a police detective. He is contacted by the police of Ryme City, a city where humans and Pokémon live together in harmony and Pokémon battles are illegal. He is informed by Harry's friend, Detective Hideo Yoshida, that Harry was killed in a car accident. Tim goes to Harry's apartment to sort things out and meets Harry's police partner, a deerstalker-clad amnesiac Pikachu, whom only Tim can understand. Tim accidentally releases a mysterious purple gas known as "R" from a vial he finds in Harry's office; they are then attacked by a party of Aipom[c] who became rabid under the gas's influence.

Pikachu believes that Harry survived the crash as the police never found his body. They meet an informant of Harry's, a Mr. Mime who directs them to an illegal underground Pokémon battle arena. The arena is raided by police and Tim is brought to Yoshida, who reveals footage of Harry's crash, explaining that it is impossible that Harry would have survived.

Tim and Pikachu are contacted by Howard Clifford, the founder of Clifford Industries and creator of Ryme City. Clifford reveals that Harry was abducted by a genetically engineered Pokémon called Mewtwo, who erased Pikachu's memory of the incident. He warns Tim that his son Roger is behind the creation of the R gas. Tim and Pikachu recruit aspiring journalist Lucy Stevens and her Psyduck and travel to the abandoned genetics lab Harry was investigating, where they are attacked by genetically enhanced Greninja. They manage to escape but Pikachu is injured in the attack. A Bulbasaur leads them to Mewtwo and despite Tim's objections, Mewtwo heals Pikachu. This causes Pikachu to remember that he helped Mewtwo escape from the lab and believes he was responsible for betraying Harry. Not trusting himself, he leaves Tim.

Pikachu discovers the scene of the crash and finds evidence that it was the Greninja, not Mewtwo, who were responsible for the crash. Back in Ryme City, Clifford exposes himself as the mastermind behind the "R" gas and the Mewtwo experiments. He explains that Mewtwo can fuse humans with their Pokémon, but only if the Pokémon is in a crazed state, thus the need for R. Clifford uses a device to transfer his consciousness into Mewtwo, unleashes the gas on the city from giant balloons and starts fusing humans with Pokémon including Lucy and Yoshida. Pikachu arrives and fights Mewtwo while Tim discovers that Roger is a Ditto and the real Roger was tied up and gagged by his father. They eventually defeat Clifford by removing the headset on his head, freeing Mewtwo from his control. Mewtwo separates the people and their Pokemon, Howard is arrested, and Roger vows to fix his father's mistakes.

Mewtwo explains that Harry had tried to save him from Howard and helped him escape, but was attacked by the Greninja. Mewtwo had decided to heal Harry's wounded body while Pikachu had volunteered to have himself fuse his consciousness with Harry's to continue their investigation, the experience erasing both their memories. Mewtwo separates the two and Tim reunites with Harry in his human body. Tim decides to stay in Ryme City to become a detective and spend more time with his father and Pikachu.
