The time has (finally) come. Ash vs. Elesa in a Pokémon Gym Battle. Ash tries to think of his strategy and comes up with one. Since Elesa uses Electric-Type Pokémon, and Ground-Type Pokémon beat Electric-Types, Ash has decided to use only his Palpitoad during the battle and leave Pikachu out. Will Ash's strategy work, especially if Elesa's other two Pokémon have no weakness against Ground-types? No, because her second pokemon is her Emolga which has the advantage over a Ground-Type because it's not always an Electric-Type, it is also a Flying-Type!
This is also the only time Ash battles an Electric Gym Leader without having a rematch.
The battle is a bit of a reverse of what happened in the Gym Battle between Ash and Falkner, with Elesa knocking out two of Ash's Pokémon with just one.
Ash's Palpitoad is confirmed to be male in this episode.
This is the first time in the anime that a gym leader's most powerful Pokémon got knocked out first before it did any real damage. The most powerful of a gym leaders Pokémon is usually knocked out last after it does collateral damage but this episode was different. This may have been due to type advantage as Palpitoad is a dual water and Ground-type and Ground is super-effective against Electric.
This is the first time Ash switched his team during a Gym Battle.
Thinking it was easy to beat Elesa, Ash only brought in Palpitoad, the only time he brought in one Pokémon to battle three
Two of Elesa's Pokemons are out when they hit the wall. The two were Emolga and Tynamo because of Ash's Pikachu.
