Vivillon was the first Pokémon used in a Gym battle against Clembot. It went up against Magnemite despite the type-disadvantage. Vivillon used Flash to blind Magnemite before the latter can use Electro Ball. After the former used Quiver Dance and Sleep Powder, it managed to defeat Magnemite with Energy Ball. However, it was defeated by Clemont's Magneton.
