Ash is personally invited to the lab of Dr. Yung to test out his new battle system. When arriving there he meets up with Misty and Professor Oak who were also invited. Dr. Yung appears and challenges both Misty and Ash to a battle. He easily defeats Misty, but his match with Ash is interrupted by a cloaked figure named Mirage Master. Mirage Master turns Dr. Yung’s experiments against him and captures him and Professor Oak! As Brock goes for help (and to get a date), Ash and Misty sneak into the castle to rescue the Professor while May and Max wait outside. However, Mirage Master seems strikingly familiar, is he possibly hiding something?
