Lenora's Herdier was revealed just before Ash Ketchum's rematch with her at the Shippo Gym. Lenora's Herdier is a completely different Pokémon all together from Lenora's Lillipup. During Ash Ketchum's rematch battle with Lenora, Lenora's Herdier was matched up against Ash's Tepig. Both Pokémon had become a lot stronger since their previous match-up and it showed during the battle. Roar once again proved to be an effective move causing Ash's Tepig to be switched with Ash's Oshawott but Lenora recalled her Harderrier right after the switch.

After the draw battle between Ash's Oshawott and Lenora's Watchog, Lenora's Herdier and Ash's Tepig were matched up again but this time the winner of the battle would win the match. Lenora's Herdier used Giga Impact on Ash's Tepig but it wasn't enough to knock it out. Ash's Tepig's speed had increased because of the training with Don George and it was able to dodge most of Lenora's Herdier Shadow Ball's. The match ended up being decided by a running charge of Lenora's Herdier's Giga Impact against Ash's Tepig's Nitro Charge but Lenora's Herdier wasn't able to withstand the attack giving Ash Ketchum the match victory.
