Entei was a physical manifestation created by the Unown of Molly's desires and lust for control. It is an illusionary Entei that appeared to Molly Hale after she made a wish to the Unown. It served as a replacement father for her while her real father, Spencer, was trapped in the Unown dimension. Entei was able to speak in the humans' language because it was an illusion created by the Unown.
He did everything Molly asked for, even kidnapping Delia Ketchum so she could be Molly's mother and providing her with illusionary Pokémon for her to battle Brock and Misty with when they entered the tower that Entei had created to rescue Delia.
When Ash attempted to confront Entei to get his mother back, his Totodile and Cyndaquil were rapidly defeated, with Pikachu only lasting longer without faring any better, and even Charizard — who had witnessed the incident on television at the Charicific Valley and come to help — was only able to hold Entei off without actually defeating it. However, when Entei was about to break Charizard's neck, Molly finally decided that she wanted things to be real again.
Accepting Molly's decision, Entei helped Pikachu and Charizard defeat the now uncontrollable Unown, subsequently bidding Molly farewell and assuring her that it would always be in her dreams.
In The Mastermind of Mirage Pokémon it was seen in Pikachu's memories.
