The Chase for Pikachu

As the dark Pokeballs continue to snatch Pokemon left and right, Ash rushes to save Pikachu. Pikachu weaves and darts to evade its evil pursuers, and lets loose with a powerful volley of Thundershock attacks to no avail. An exhausted Pikachu falls from the immense height of Mewtwo's main stairwell, as Ash dives down the exhaust shaft after his friend into the bowels of Mewtwo's Palace.
