This is the only time that the move Magnitude is used in the anime. Due to an incident with a banned Advanced Generation series episode featuring the move Earthquake, Magnitude would never be used again in the anime due to its extreme similarity to Earthquake.
Ash and Gary end their rivalry and become friends again, just as they were when they were little.
Gary is revealed to have obtained a Scizor and a Golem.
When Charizard uses Seismic Toss on Blastoise, the globe appears as usual, but, whereas normally specific shapes on the globe cannot be made out, Asia and Australia are prominently seen.
Gary has Scizor dodge Muk's Sludge Bomb, even though a Poison-type move would have no effect on Scizor, a Steel-type Pokémon.
