Barry's Empoleon is Barry's main Pokémon.

Barry's Empoleon also appeared when Barry wanted to battle Ash's Gible (who was still a wild Gible at the time) so that he could catch it in the end. One of its powerful Hydro Cannon attacks, though, sent it flying, thus ruining Barry's attempt at a capture. It later re-appeared battling against Ash's Gible when Barry challenged Ash Ketchum to a battle. Due to it being overall stronger than its opponent, and Gible's disobedience towards Ash Ketchum during the fight, it managed to knock out its opponent.

Barry's Empoleon was Barry's first choice for his battle against Ash Ketchum in the town near Sunyshore City. During the battle, Empoleon launched a powerful Hydro Cannon attack which sent his opponent, Ash's Monferno, flying into the nearby forest. As Ash Ketchum was calling out to it, Team Rocket suddenly appeared and managed to trap Ash Ketchum and the others, as well as capture Ash's Pikachu, Dawn's Piplup and Barry's Empoleon shortly afterwards. In the end, with the help of Paul's Electabuzz, who aided in stopping Team Rocket's destroyed mecha from collapsing and injuring the captured Pokémon, and Ash's Infernape, who had just evolved unexpectedly from Monferno, Barry was reunited with his Empoleon.
