Scientist Dr. Fuji is hired by Giovanni, leader of Team Rocket, to utilize his expertise in cloning in order to create a living weapon based on an eyelash from the mythical Pokémon Mew. Fuji is revealed to be allying with Giovanni as a means to fund his side project: the resurrection of his deceased daughter Amber. In a laboratory, the weapon eventually gains sentience and is named Mewtwo. Mewtwo befriends the salvaged consciousness of Amber, named Ambertwo, as well as the clones of other Pokémon in the laboratory. However, Mewtwo is left deeply traumatized after Ambertwo and the rest of the clones decompose and die. To stabilize him, Fuji tranquilizes Mewtwo, causing him to fall asleep and forget the time he spent with his friends. However, before he re-awakens, Mewtwo recalls Ambertwo's last words to him: "Life is wonderful".
