Lenora's Herdier was her main Pokemon in the anime.
Lenora's Lillipup debuted in The Battle According to Lenora!, where it battled Ash's Tepig. When it was first sent out, both Iris and Ash thought it was useless and weak due to its cuteness. However, it was shown to be fierce in battle, surprising Iris. In its battle with Ash, it used Roar to send Tepig back, forcing Oshawott to come out. It was then called back to its Poké Ball. Later it was sent back out when Watchog defeated Oshawott. It was able to easily beat Ash's Tepig with a powerful Take Down, causing Ash to lose the battle to Lenora. Lillipup evolved before the rematch.
Herdier was used to battle Ash's Tepig during Lenora's rematch with him. Since it's evolution it had more powerful attacks including a stronger Shadow Ball, being capable of using four Shadow Balls at once, Protect to block the opponents attacks and the powerful Giga Impact to replace Take Down. Although it was even more powerful than it had been before, it was eventually defeated by Ash's Tepig's Flame Charge attack.
