Battle for the Underground!.With Team Rocket having hacked into the subway system's computers, the Subway Masters cannot help but to watch as Team Rocket keeps on releasing fake trains as distractions. Ash suggests inspecting them one by one until they find the right one. Meanwhile, Dr. Zager is planning on rendezvousing with Jessie and James at a designated location. Cilan suggests that Team Rocket is planning to meet outside of the subway and that they are on their way to the Anville Town rail yard. Meanwhile, Pikachu begins to call out other Pokémon to break out of the train. The Subway Masters rendezvous with the gang and plan to drive out of the underground subway station to catch up to Team Rocket, just as the Pokémon have finally cut a hole through the door of the train. Meowth goes to check up on the Pokémon only to see that Pikachu has broken free. Pikachu realizes that Meowth has been lying all along and gets infuriated.

Ash decides to go over to the train car and help them out. Using a Chandelure's psychic powers, he is transported over to the train car...
