In A Snow Day for Searching!, Goh used Butterfree alongside some of his other Bug Pokémon to find the bone of a wild Cubone, which he later caught.
During a food shortage in Panic in the Park!, Butterfree joined a group of Goh's Bug-type Pokémon to rebel and target Darmanitan, Grimer, Ekans, and Stantler. When Golurk lost control, the conflict was dropped as Butterfree helped with the protection of Goh’s three Cascoon.
Butterfree is shown to be calm. He also is shown to be friendly and listen to its trainer as seen in A Snow Day for Searching!, when Cubone's bone was missing, Goh sent him out to search for it.
