Ash continues his training with Gligar, but finds out it has become fearful of battles since the battle against Paul's Gliscor. The group meets Gary again and Ash asks Gary to help him solve the problem with Gligar, and Gary might have something that could change Gligar forever...
Instead of Professor Oak's Pokémon lecture, the end of this episode featured a special trailer for Giratina and the Sky Warrior.
Music from Pokémon Ranger and the Temple of the Sea is used as background music.
Dawn narrates the next episode preview.
During the Diamond & Pearl series, Ash, Dawn, and Brock each have owned a Generation II Pokémon; however, this episode, the previous episode, before Gligar evolved, and after Swinub was captured, are the only times in the series in which all three have a Generation II Pokémon with them: Ash has Gligar, Dawn has Swinub, and Brock has Sudowoodo.
This is the second time that Gary appears in Sinnoh, the first time being exactly forty episodes ago. Coincidentally, both times Ash and his friends were on the way to Hearthome City.
This episode first aired in Japan in the same week as the dub of Riding the Winds of Change, the episode in which Gligar was caught, first aired in the U.S.. This happened again with Swinub.
Both an earlier episode, and a later episode had similar episode titles to this one. All three are a pun on the phrase "fighting fire with fire".
Interestingly, the later episode also featured an evolution.
In the English dub, when Meowth is about to explain what Team Rocket could use Gligar for, Jessie says, "I'm sensing a scene change," possibly providing an example of breaking the fourth wall.
This is the first time one of Ash's Pokémon evolves using an item.
