Nosepass first appeared in Blowing Past Nosepass I, when Roxanne sent it out during her Gym battle against Sapphire's Rono. Despite the type-disadvantage, it managed to overwhelm Rono when Magnet Pull prevented him from switching out and moving. From that point on, Nosepass used a combination of Rock Throw and Rock Slide to defeat Rono. However, Sapphire figured out Nosepass's weakness as it would usually face north and stay that direction. With Nosepass facing the other way, Rono was able to escape the rubble and defeat Nosepass.
Roxanne usually kept Nosepass's Poké Ball in a hollowed-out book. During battle, it knew some techniques that prevent the opponent from escaping. However, only a few such as Sapphire and Courtney knew their way around it.
Nosepass appeared in The Winner by a Nosepass, where Roxanne used it in a Gymbattle against Ash. As Pikachu became worn out after battling her Geodude and had trouble with his Iron Tail technique, Nosepass was able to get the upper hand. However, Nosepass struggled to keep up with Pikachu's speed after he used Quick Attack to dodge. Later, it unknowingly blasted off Team Rocket after using Thunder Wave and made a hole in the battlefield. Even though Pikachu started to get tired even more, a Zap Cannon coming from Nosepass recharged him and Nosepass was defeated by Pikachu's Iron Tail, which earned Ash the Stone Badge.

Very little is known about Nosepass's personality, as it was only seen during the Gym battle with Ash. However, compared to Roxanne's Geodude and Ash's Pikachu, Nosepass wasn't too lively or active as it didn't move around too much.
After Roxanne's Geodude lost to Pikachu's Iron Tail, Nosepass was the next opponent Pikachu faced. Nosepass had very little trouble at first with the battle as Pikachu hadn't mastered Iron Tail. However, despite Nosepass's combination of Rock Tomb and Sandstorm, it struggled to keep up with Pikachu's speed. Nosepass was defeated when Pikachu successfully mastered Iron Tail and got charged by Zap Cannon.
