Pokémon 3: The Movie 2001

In the town of Greenfield, research scientist Professor Spencer Hale conducts research on the elusive Pokémon Unown. He and his assistant, Skyler, discover a site of ruins, but Hale is sucked into the dimension of the Unown. His disappearance leaves his young daughter Molly alone, her mother having disappeared previously. Molly finds a box of tablets containing Unown images and begins assembling the letters, which summons the Unown themselves. The Unown, sensing Molly’s desires, use their powers to make Molly’s wishes come true, transforming her manor house into a crystal-like palace which spreads across the town and cuts her off from the world. An illusionary Entei is created to represent Molly’s father, who agrees to fill this role for her.

Meanwhile, Ash Ketchum and his friends meet and befriend a trainer named Lisa, arriving in Greenfield just in time to see the crystallization slowly in progress. They also meet up with Professor Oak and Ash’s mom, Delia, who arrived to help with the situation, as the Ketchum’s are old friends of the Hale’s. However, Entei kidnaps Delia, following Molly’s request for a mother as well, and he hypnotizes her into thinking she is Molly’s mother. Ash, Misty, Brock, and their Pokémon head out to the mansion to save Delia, communicating with Oak and Skyler thanks to a PokéGear device given to them by Lisa. Team Rocket try investigating the mansion, but Entei blasts them into the depths of the mansion. Molly watches Ash’s Pokémon in action through a television and falls asleep, imagining herself being a Pokémon Trainer; Delia is snapped out of her trance by seeing Ash on the TV. Entei creates a dream version of Molly as an adult to let her battle the three, first fighting and defeating Brock with her stronger dream Pokémon, and then having a more friendly fight with Misty.

Ash locates Molly and Delia, attempting to convince Molly to leave with them, but she is too scared and refuses, causing the power of the Unown to fight back. Entei returns and battles Ash, defeating his Pokémon and nearly killing him and Pikachu. However, having witnessed the crisis on TV in Charicific Valley, Ash’s Charizard appears in time to rescue Ash and Pikachu. Entei engages Charizard in a duel and eventually tries to kill him. But then Molly, who realizes that her desires are causing more harm than good, tells Entei to stop fighting. She is finally convinced to let go and leave with them, as Entei reveals he will soon depart, having served his purpose to follow her wishes.

The Unown suddenly begin losing control of their powers and start to seal the group in the mansion. The group (plus Team Rocket) escape to the main hall where the Unown are. Pikachu and Charizard attempt to break the forcefield protecting the Unown, but they are unsuccessful, until they are joined by Entei, combining their powers to destroy the shield with Molly’s support. Entei sacrifices himself and the Unown return to their dimension, reversing all of their effects on the world and returning Hale to the ruins where he originally vanished.

The group ventures outside, where Oak, Skyler, Lisa, and others meet them. Team Rocket hides in the mansion upon seeing the police outside and declare that they will always have another opportunity to catch Pokémon. Charizard and Lisa depart from Ash’s company, and Molly reunites with her biological father as well as with her long-lost biological mother.
