Doctor Yung

Dr. Yung invented the Mirage Pokémon system. This appears to be a project he spent many years on, as Professor Oak acknowledges. Yung is shown to have a combination of great intellect and battling skill, but still has a sort of mysterious air about himself. He challenges Ash and his friends to battle with him using a Mirage Aggron his system has generated. Misty eagerly accepts his challenge and uses her Staryu, but she lost easily when the Aggron showed off one of Yung's system's features - the ability to use any attack, in this case Bullet Seed. Ash challenged him next with Pikachu, but before the battle could begin, the Mirage Master (Japanese: ミスター・ミラージュ Mr.

Mirage) captured both Yung and Oak by commandeering the system. While Ash and his friends attempted to mount a rescue mission, Mirage Master tortured Oak with the intent of gaining the access password to Oak's laboratory database. He spoke of his contempt for the flaws inherent in every Pokémon and of his desire to create a Pokémon free of these flaws. He is especially enraged when a Mirage Mew appears, which he declared a 'flawed specimen.' Oak initially resisted the torture and refused to give the password. As a backup plan, Mirage Master used some of his Mirage Pokémon to capture Pikachu after ambushing it.

He then strapped it to a table and used a special machine to scan its memories for data, causing it great pain. This finally broke Oak's resolve, and he surrendered the password, "REDGREEN." Using a combination of his new access to Oak's laboratory's database and his ability to hack the servers of Pokémon Centers worldwide, Mirage Master began forming his perfect Pokémon. When Ash, and later Misty and May arrived to confront him, Mirage Master completed the experiment, creating a Mirage Mewtwo. He demonstrated its power by instantly defeating all of the other Mirage Pokémon, then he attempted to kill Oak, who had to defend himself with a Dragonite.
