Norman's Slakoth was used in Norman's Gym battle with Ash. Despite being hindered by its special ability, Slakoth proved to be a formidable opponent. It first battled Ash's Pikachu, and whenever its Truant ability kicked in, it simply avoided Pikachu's attacks. Slakoth was surprisingly difficult to hit, stepping aside to avoid Pikachu's Quick Attack. It was also shown to be flexible, since it was capable of leaning back to evade Pikachu's Iron Tail. When it was not using Truant, Slakoth attacked Pikachu with a total of three powerful attacks, eventually forcing Ash to recall Pikachu. However, Slakoth was no match for Ash's Torkoal and was defeated by a single Flamethrower.
