At the restaurant, while eating lunch, Pikachu takes a particular liking to eating ketchup from the bottle. The restaurant owner explains to Ash and his friends, as a mysterious patron listens close by, that Dark City has two rival Pokémon Gyms, the Yas Gym and the Kaz Gym, lead by Yas and Kaz, respectively. Both Gyms seek official status, but to do so, they would need the approval of the Pokémon League inspector, who is scheduled to arrive at any moment. As there can only be one official Gym per city, each of the two Gyms seeks to eliminate the other before the inspector arrives. The restaurant owner further explains that Pokémon Trainers who pass through Dark City are typically recruited for the cause of either Gym. Suddenly, a street fight between the two Gyms breaks out outside the restaurant. The Yas Gym’s Scyther and the Kaz Gym’s Electabuzz in particular are dispatching the men of the opposing Gym with ease, all the while damaging the town and terrorizing the townsfolk. As Ash and his friends watch from the safety of the restaurant, the three note that the fighting is not as much of a proper Pokémon battle as it is just a petty gang war.
