A Mirage appears to Professor Oak, and the Mirage Master snaps at the sight of it, viciously attacking it with his Mirage  and declaring it to be a "flawed specimen".

Oak initially resists the threats and refuses to give the password. As a backup plan, Mirage Master uses some of his Mirage Pokémon to capture Pikachu after ambushing it.
