Golduck first made his appearance in A Tale of Ninetales, where an accident caused Red and Blue to switch parties, with Golduck ending up with Red. During his stay on Red's team, he, along with the rest of Blue's party, experienced Red's positive style of training, as opposed to Blue's fiercer one. When the Pokémon were returned to their respective Trainers, Blue's Pokémon ended up friendlier to Blue as a result of this type of training.
Golduck later appeared during the battle against Team Rocket, where it used its psychic powers to locate the Pokémon who was responsible for setting up a barrier around Saffron City, preventing access to the city. Using this information, Red and Pika defeated the Pokémon, turning the barriers off.
In this chapter, Golduck was mainly used to transport Blue across water. He was later used in battle against Agatha, who was able to defeat her Arbok.
Golduck was used during Blue's battle with Red in order to learn the ultimate moves from Kimberly. During the battle, it caused heavy damage to Gyara, but was defeated by Lax when it used Earthquake while Golduck was digging. Golduck was later used against the Trainer Tower A.I., known as "R", but was knocked back and was unable to attack.
