In JN015, Goh used Scyther alongside some of his other Bug Pokémon to find the bone of a wildCubone, which he later caught.
During a food shortage in JN023, Scyther led a group of Goh's Bug-type Pokémon during a rebellion; and they targeted Darmanitan, Grimer, Ekans, and Stantler. When Golurk lost control, Scyther protected Goh's three Cascoon.
Scyther is a fast and powerful Pokémon, thus Goh had the most trouble to catch it out of all the Kanto-native Bug types he went after. It is enthusiastic about battling and staying active. In Serving Up the Flute Cup!, it followed Mimey's kung-fu exercises alongside its Trainer, Scorbunny, the Professor, and Chloe. It was later shadow-boxing as an effort to get Goh's attention to bring it to the Battle Frontier Flute Cup. Scyther is also shown to have a quick temper, as seen in JN015; when a group of Geodude threw snowballs at it, hitting it in the face, Scyther started chasing them. These behaviors particularly contrast with Goh's Pinsir, who tried to avoid being selected for the Flute Cup and gets along with Goh's smaller Pokémon like Caterpie. However, despite its rough demeanor, Scyther enjoys a hug, as seen in Best Friend...Worst Nightmare!, when it accepted one from Ash's Dragonite.
After its capture, Scyther quickly became one of Goh's most used Pokémon, next to Raboot. Despite its strength and confidence, however, Goh and Scyther are not as in sync with each other compared to Raboot, and Goh's cautious strategy in the first round of the Flute Cup led to Scyther's quick defeat. Scyther didn't appear too upset by the loss, returning from the Pokémon Center for another battle. Like Scorbunny, it seemed more concerned with how hard Goh was taking his first defeat.
Scyther is protective of other Pokémon, as seen in JN023, when it shielded a group of Goh's Bug types from Darmanitan's attack. Scyther is also a natural leader, as seen when it commanded Goh's Bug-types to attack Darmanitan and its allies.
