In Working My Way Back to Mew!, Goh found Butterfree at Vermilion Forest and chased after it as Butterfree flew at the top of a large tree. Goh threw a Poké Ball at it, but missed as Butterfree was far too high for Goh to reach it. When Goh slipped and dropped his Poké Ball, Butterfree attempted to fly away, but Scorbunny kicked the Poké Ball directly onto Butterfree, resulting in its capture.
In Panic in the Park!, Butterfree joined a group made up of Goh's other Bug-type Pokémon, which came into conflict with another faction led by Goh's Darmanitan, which was made up of Normal and Poison-type Pokémon, after the food around Cerise Park had been stolen. Butterfree and Venomoth combined their Stun Spore attacks, which were blocked by Grimer's Poison Gas. As the battle escalated, Scyther took control of the Bug-type group, but the infighting ended when Golurk lost control of itself, causing Cerise Park to become flooded. Butterfree joined the rest of the Pokémon in saving Goh's three Cascoon, allowing them to evolve into Dustox and clear the storm with Sunny Day.
In There's a New Kid in Town!, Goh enlisted the help of Butterfree and Venomoth by having them use Stun Spore to locate the invisible crying Sobble, as its crying was affecting all the Pokémon in the proximity, and its paralysis caused Sobble to reappear, but it kept crying until Dragonite hugged the Water Lizard Pokémon to comfort it, which caused Sobble to fall asleep and stop crying.
In JN107, Goh used Butterfree, along with other Pokémon in the park, to create a fountain so that Grimer and Froakie could live in Cerise Laboratory without dirtying the stream.
Personality and characteristics
Butterfree and Venomoth
Butterfree is shown as being a helpful Pokémon for restraining its targets with its Stun Spore attack. Its also useful whenever Goh requires aerial assistance such as searching for lost items or Pokémon.
Butterfree is usually seen alongside Venomoth, and they often combined their Stun Spore attacks together to cover a wider area whenever Goh deems it necessary. They also perform this combo on their own accord, seen when Butterfree and Venomoth used it during their confrontation with the Normal and Poison-type Pokémon faction in Panic in the Park!.
