When Ash and co. were traveling towards Daybreak Town for Dawn's next Pokémon Contest, a mysterious Pokémon Trainer specializing in martial arts, named Clayton, challenged Ash Ketchum and his Buizel to a battle after seeing how Buizel saved Gible who had fallen into a river. Clayton's Mr. Mime proved to be a really strong opponent, though, as it managed to dodge Buizel's Aqua Jet and SonicBoom attacks by skillfully using its Psychic and Double Team moves, eventually knocking Buizel out with a powerful ThunderPunch. Ash Ketchum and Buizel, determined to make up for the loss by getting stronger, started training with Clayton's help so that Buizel could learn a new move; Ice Punch. He told them that, in order to master the move, they had to work on improving their speed and concentration.

At first, the progress of Ash's Buizel's training seemed to be really slow. However, after training overnight using unstable and light objects as targets for its punches, like floating leaves, Buizel managed to master the move completely. After the completion of Buizel's training, Ash Ketchum challenged Clayton to a rematch, and Clayton accepted. Ash's Buizel proved to be more of a challenge for its opponent, Mr. Mime, this time and after activating its ability, Swift Swim, in the midst of the battle due to a sudden rain, Buizel managed to increase its speed and finish Clayton's Mr. Mime off with a powerful Ice Punch. Clayton then acknowledged Ash's Buizel's improvement and praised its skills, but also put emphasis on the fact that Buizel still had a long way to go and had to keep on training.
