The time finally comes for Ash's fourth Gym Battle in the Johto League. In the Ecruteak Gym, he must face Morty and his team of powerful ghost Pokémon. But Ash has already been witness to Morty's Gengar and been stunned by the Pokémon's power. Does he have a chance against a whole team of such powerful Pokémon phantoms? As Ash muses over battle strategies, Nurse Joy overhears and suggests he uses his Noctowl.
