Pokemon: Detective Pikachu, 2019 Movie

In the Pokémon universe, Tim Goodman is a 21-year-old insurance salesman who had given up Pokémon training due to the death of his mother and the absence of his father, Harry. While hanging out with his friend Jack, Tim learns that Harry has died in a car crash while investigating a case.

He travels to Ryme City, a metropolis that outlaws Pokémon fighting and pushes the bonds of humans and Pokémon alike, to collect Harry’s assets. Tim also meets Lucy Stevens, a fluff columnist who wants to be a reporter and is suspicious of Harry’s death, and her Psyduck. While reminiscing in his apartment, Tim encounters a deerstalker-clad Pikachu that can speak and only he can somehow understand. They are attacked by a party of Aipom under the influence of a purple gas that Tim accidentally released, but they both escape.

They take shelter at a café where Pikachu reveals that he is an amnesiac detective who was Harry’s police partner and that they were investigating a case together when Harry disappeared; the only clue to Pikachu’s identity and Harry’s whereabouts being the deerstalker hat labelled with Harry’s name. They look for Lucy, who reveals that while investigating she discovered that Harry was once at Ryme Wharf, and set out to find clues.

Tim and Pikachu interrogate a Mr Mime who directs them to an illegal underground fighting arena owned by Sebastian, whose Charizard was fought before by Pikachu. Sebastian demands a rematch, but Pikachu cannot remember his own moves and Sebastian gives Charizard the same mysterious gas labeled “R”. While Tim attempts to save Pikachu, Sebastian accidentally releases R, causing the entire stadium to get affected alerting the authorities, but not before revealing to Tim that he got R from “the doctor.”

Tim argues with police lieutenant Hideo Yoshida that Harry may be alive, but Yoshida shows him the video of Harry’s crash, explaining that it would have been impossible. Soon, Tim and Pikachu are met by Ms. Norman who takes them to see Ryme City’s benefactor Howard Clifford, who had once tried to cure his ailing condition and instead created the humanitarian city. He shows him more revealing footage of Harry surviving the attack, apparently caused by the recently escaped Mewtwo, but that he was taken away by the Pokémon, leaving Pikachu with amnesia. Howard tells them to watch out for his son, Roger, who he claims is in control of his company and the city. With this new information, Tim and Pikachu recruit Lucy and Psyduck.

The group breaks into the lab facility Harry was investigating and learn that Dr. Ann Laurent, the doctor Sebastian mentioned, was experimenting on Mewtwo, who had been recaptured after escaping 20 years earlier, and had apparently hired Harry to aid them. They are soon attacked by several Greninja who chase them out of the building, but are fended off by Psyduck. They then escape a field of colossal Torterra, but Pikachu is gravely injured. Tim manages to communicate to a Bulbasaur and takes Pikachu to a clearing in the forest where they are greeted by Mewtwo, who heals Pikachu. Mewtwo attempts to reveal its intent, but was captured by Roger. Thinking that he betrayed Harry to a vengeful Mewtwo, Pikachu leaves Tim while the others return to Ryme City to warn Howard.

Pikachu comes across the area where Harry crashed his car and finds proof that it was not Mewtwo who attacked, but the Greninja. Tim reaches Howard, but learns too late that he intends to transfer his consciousnesses into Mewtwo and use R so that the Pokémon can become docile enough for him to fuse them with their owners, thus allowing humans to evolve within their Pokémon. As Howard in Mewtwo’s body releases the gas into the world, Pikachu arrives and finally summons his electricity powers to battle Mewtwo. Meanwhile, Tim finds out that “Roger”, and in-turn Ms. Norman, was really a shape-shifting Ditto who was modified to transform into humans, with the real Roger having been tied up and hidden. Tim subdues Ditto with R while Pikachu fends off Mewtwo long enough for Tim to free Mewtwo from Howard’s control.

Mewtwo restores everyone to normal while Howard is arrested by the police. Roger is impressed with Lucy and hires her as a full-time reporter. Mewtwo then reveals that Harry was in fact fused with Pikachu in order to heal him. The fuse erased Harry’s memory while keeping his consciousness within Pikachu. After Mewtwo unfuses them with the help of Tim, a fully revived Harry offers Tim the chance to return home, but Tim decides to stay in order to learn how to become a detective and spend time with him and Pikachu.
