Pokémon: Mewtwo Strikes Back - Evolution 2020

Here is the rephrased section:

Dr. Fuji, a brilliant scientist, is enlisted by Giovanni, the enigmatic leader of Team Rocket, to harness his expertise in cloning for the creation of a living weapon based on an eyelash from the mythical Pokémon Mew, voiced by Koichi Yamadera. The fruit of their labor takes the form of Mewtwo, voiced by Dan Green, a being imbued with incredible psychic powers and a sentience that rapidly develops. As Mewtwo awakens from his slumber in a laboratory on New Island, he is met with the revelation of his origin as a clone of Mew, an entity renowned for its capacity to conjure torrential rains and coax blooming flora into barren wilderness.

Seething with indignation at being perceived solely as a tool by Dr. Fuji and his cohorts, Mewtwo unleashes his full fury, destroying the laboratory and claiming the lives of those who had created him. Giovanni, observing the devastation from afar, approaches Mewtwo and convinces him to collaborate in refining his abilities for the purpose of dominating the world. Throughout this period, Mewtwo repeatedly poses existential questions to himself: “Who am I?” and “To what purpose do I live?”

However, as Mewtwo becomes aware of his true purpose - serving as a weapon for Giovanni’s ambitions - he breaks free from his prison and sets his sights on exacting revenge against humanity. After rebuilding the laboratory and establishing a stronghold on New Island, Mewtwo extends an invitation to various trainers, conveyed through holographic messages, to engage in a battle royale with the world’s greatest Pokémon trainer.

Ash (Sarah Natochenny), Misty (Michele Knotz), and Brock (Bill Rogers) receive the summons, as they possess Pikachu and Togepi (Satomi Korogi), and accept the challenge. Upon their arrival at Old Shore Wharf, however, Mewtwo unleashes a storm, prompting harbor master Miranda (Lisa Ortiz) to seal off the port city for safety reasons. As a result, Ash’s group is picked up by Team Rocket - Jesse (Michele Knotz), James (James Carter Cathcart), and Meowth - disguised as captains on a Lapras-shaped sailboat.

After their vessel sinks in the midst of the ocean, Ash and his companions utilize their Pokémon to navigate to New Island. Upon disembarking, they are escorted into Mewtwo’s palace by the woman who appeared in the holographic message, only to discover that she is actually Nurse Joy (Alyson Leigh Rosenfeld), brainwashed under Mewtwo’s mental control.

As Mewtwo unleashes its arsenal of cloned Pokémon, it becomes clear that these artificially created entities are not only eerily identical to their originals but also boast an unsettling level of power. Meanwhile, Team Rocket’s James Carter Cathcart (Meowth) covertly infiltrates the New Island palace through a hidden sewer entrance, accompanied by Mew in its innocent and curious form. Their clandestine exploration leads them to stumble upon Dr. Fuji’s groundbreaking research on cloning machines, which they eagerly exploit to further their own nefarious objectives.

As the cloned Pokémon effortlessly dispatch their opponents, Mewtwo confiscates the defeated trainers’ Pokémon using its own Poke Balls, including Pikachu (Ikue Otani). Ash Ketchum hotly pursues his captured Pikachu down the labyrinthine corridors of the cloning lab, where he encounters a duplicated Meowth that has formed an unlikely bond with its original. Fueled by determination and a sense of justice, Ash destroys the cloning machine, liberates the captive Pokémon, and leads them in a bold confrontation against Mewtwo’s formidable clone army.

In a shocking revelation, the enigmatic Mew emerges from the shadows, prompting Mewtwo to challenge it to prove its superiority. The original Pokémon, now freed from their artificial duplicates, clash with their clones in a spectacular battle that echoes the anguish and pain felt by all parties involved. Horrified by the devastating consequences of this unrelenting conflict, Ash Ketchum inserts himself between a psychic blast generated by Mewtwo’s fury and the retaliatory energy emanating from Mew. As a result, Ash is petrified, his body frozen in time.

Pikachu, moved by its trainer’s selfless sacrifice, attempts to revive Ash using its electric powers but ultimately fails. However, it soon becomes apparent that the tears shed by the Pokémon possess the power to heal and restore life to those who have been lost. Moved by Ash’s unwavering dedication and unshakeable spirit, Mewtwo is struck by a profound realization: its origins should not define it; instead, its choices in life will ultimately shape its character.

As Mewtwo departs alongside Mew and the clones, it rewinds time to just before the trainers’ departure from Old Shore Wharf, effectively erasing all memories of the event. Upon returning to the Pokémon Center, Nurse Joy has been restored to full health, and she reopens her sanctuary to welcome back the weary trainers. The storm that had beset the town begins to clear, as Ash gazes upwards at Mew soaring through the clouds, its majestic presence a reminder of the awe-inspiring mysteries hidden within the realm of Pokémon. Meanwhile, Team Rocket finds itself stranded on New Island but revels in their unexpected respite from the chaos.

In the credits, a fleeting glimpse is afforded of Mewtwo, Mew, and the clones hurtling towards the majestic slopes of Mount Quena, leaving behind the remnants of an unforgettable adventure that will forever shape the destinies of Ash Ketchum and his companions.
