This is the first time Ash calls back his Pokémon and then sends them back into battle two times during a Gym match. It is also the first time Ash calls back three Pokémon during a Gym match without any of them having fainted.
The length of time between Ash's Veilstone and Pastoria Gym challenges is 15 episodes, which is half of the 30-episode-long "drought" between Ash's Eterna and Veilstone Gym challenges. Within the games, this is also the longest distance between two Gyms.
Team Rocket doesn't recite the motto or blast off in this episode. Like in Nibi Gym Battle! (1997), they only appear at the very beginning and the very end of the episode.
Ash has a Gym battle with Crasher Wake and wins, earning the Fen Badge.
