|“||We dreamed of creating the world's strongest Pokémon... and we succeeded.||”|
–Dr. Fuji, Mewtwo Strikes Back
Dr. Fuji was the head scientist of Team Rocket.
He was the leader of the scientists who created Mewtwo. Above was his last words before he perished when Mewtwo destroyed that island where Team Rocket's scientific base. He also appeared in Mewtwo's Origin as the narrator. He did not create Mewtwo for money, though he used the opportunity to see what cloning would be like, because he wanted most of all to bring his daughter Amber back. He messed up on one of his experiments, and he put her in a black and white world. He could watch her live, and he wanted to be the last one living to bring her back. She was not, Mewtwo was. Later, all his studies gained the attention of Giovanni who said he would fund Fuji's project if Fuji also cloned the legendary Pokémon, Mew. This resulted in the creation of Mewtwo.
- Dr. Fuji heavily resembles Dr Tenma from the Astro Boy anime.
