BiographyMolly lives in the beautiful town of Greenfield in the Johto region with her father, Professor Spencer Hale. Her mother disappeared some time ago and her father is often away studying ancient Pokémon. Molly’s father was good friends with Ash's mother when they were in school, and Molly and her parents visited Pallet Town when Ash and Molly were both very young.
After Molly's father went missing during an archaeological dig with his assistant Skyler regarding the Unown, she makes a wish that her father would return using the stone tablets Skyler retrieved from the ruins, summoning the Unown to her side. The Unown her father had accidentally discovered reacted to Molly's wishes and imagination and created an Entei. Believing the legendary Pokémon her father had told her stories of is in fact her father, she continued to imagine and the Unown made her dreams a reality.
The mansion and surrounding fields were transformed into crystal formations, impenetrable to outsiders. Meanwhile, Ash, Misty, Brock, Professor Oak, and Ash's mother arrive in Greenfield and witness the transformation. Seeing Ash's mother on television, Molly wishes for her own mom, and Entei proceeds to kidnap Delia Ketchum, hypnotizing her into believing she was Molly's new mother.
When a bulldozer attempts to breach the crystal landscape around Molly's mansion, Molly's demand for them to go away is answered by the Unown, before Molly then sends a video email to the Greenfield Pokemon Center, telling everyone there to leave her and her parents alone.
Ash, Misty, and Brock make their way to the interior of the crystal formation to rescue her, but are confronted by Molly who wishes to battle them. Brock is the first to take on Molly, but her dreamed-up Pokémon are much stronger than even his Onix. Next to fight her is Misty, but Misty’s water Pokémon are swiftly defeated by yet more imaginary Pokémon.
Whilst the battles take place below, Ash ascends the tower and tries to rescue his mother. Molly becomes upset, which causes huge spikes to shoot up from the floor. Entei appears, and Ash proceeds to battle him with the help of Charizard, who also saw Ash on television. However, Entei proves too powerful for Charizard, and soon Entei has Charizard pinned under his foot as he prepares the finishing blow. Molly stops Entei from killing Charizard, and decides to go with the others and leave the mansion. But the Unown have built up too much Psychic energy and are out of control, which leads to Entei destroying the energy and himself. The Unown disappear, as do the crystals, and Molly’s father is returned. Molly emerges from the mansion with Ash and the others to reunite with Skyler, Professor Oak, her servants, and the police. The end credits also show Molly’s mother returning to the mansion.
