Unown

The Unown send Professor Hale into their dimension. Later, Molly Hale releases Unown from the stone tiles in a box in her house. The Unown, reading Molly's mind, make her wishes come true, including turning Greenfield into crystal and creating Entei to be Molly's new dad. Because Molly also wants a mother, Entei kidnaps Ash Ketchum's mom. Eventually, Molly realizes that what she is doing is wrong and she wants to stop, but the power of the Unown is out of control. Entei destroys the psychic energy shield around the Unown, sacrificing himself in the process. The Unown are turned back into stone tiles, and Professor Hale is released from the Unown dimension.
