Strange phenomenon have been happening at Sakuragi's Laboratory lately such as rooms getting ramsacked. On hunting down the problem, Ash & Go find out that the culprit is none other than the Gengar they had encountered previously. Ash & Go both intend to catch the Gengar but Ash starts acting very weird and even almost falls down the stairs. Is Gengar responsible? Will they stop Gengar?

Ash intended to battle the World Champion, Leon again, so he has entered the Pokémon World Championships. To qualify for the final few, he has to battle other trainers who are qualified. To start with, he will face Visquez, the deputy Gym Leader at Vermilion City Gym while Lt. Surge is away. Each trainer uses two Pokémon with Ash picking Pikachu and Gengar and Visquez picking Electrode and Raichu. Will Ash manage to win?
