Ash learns that the next Gym is located in Shalour City.
Ash reveals that Thunderbolt is his favorite move.
In this Gym battle, Ash used his full party while Grant only used his Onix and Tyrunt, making it a two-on-three Gym battle, the first one of its kind seen in the anime. This is the third Gym battle that Ash had where he was allowed to use more Pokémon than the Gym Leader. The first two were his rematch with Whitney in Miltank! Revenge Battle!! (2000) of the original series and his battle against Roxie in Rocking the Virbank Gym!: Part 1 (2012) and Rocking the Virbank Gym!: Part 2 (2012) of the Best Wishes series.
Ash has a Gym battle with Grant and wins, earning the Cliff Badge.
