Later, in Pooh's Adventures of Pokémon: Mewtwo Returns, Mewtwo took Christopher Robin, to be safe from Giovanni. Then, Pooh and his friends reunited w/ Ash, Misty, Brock, and Pikachu to find him at Purity Canyon. Team Rocket's combat unit arrived to take Mewtwo and his clones, and claim Mt. Quena as a new laboratory. Pooh and his pals freed Mewtwo from Giovanni's machines and revived him in the spring water. After that Mewtwo erased Giovanni's memory, spared the memories of Pooh and his friends, returned Christopher Robin to them, and decided to live with them but at Skull. Thus, Mewtwo became the father figure to Pooh and his pals, protective, but calm and level-headed. By the end of Winnie the Pooh And The Secret of Kells he became Aisling's adopted father.
