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.
