Steelix appeared alongside Morrison's other Pokémon as they are being introduced to Ash and his friends.[1] After a day of hard training with Ash, Morrison laid on grass with his Pokémon, including Steelix, to rest a bit.[2] Morrison later used Steelix in a battle against Ash in the Ever Grande Conference. Steelix fired a Dragon Breath to strike Pikachu, who dodged using Quick Attack. However, Steelix used Iron Tail to strike Pikachu, then used Dig. When Steelix came out, it was hit by Pikachu's Quick Attack. The two sides then used Iron Tail, but Pikachu was defeated by this attack.
Ash then sent Torkoal, who used Iron Defense to protect itself from Dragon Breath. It then fired Overheat, beating Dragon Breath and hitting Steelix with that attack. As Steelix repeated its attack, Torkoal used Flamethrower, creating an explosion. Steelix used Dig, beating Torkoal's Iron Defense and hitting it. Firing another Dragon Breath, Steelix defeated Torkoal as well. Ash then sent Grovyle, who swiftly avoided Iron Tail and retaliated with Bullet Seed, but missed as Steelix used another Dig. Grovyle dodged Dig, and when Steelix used Dragon Breath, Grovyle charged into the attack with Leaf Blade. Using that move, Grovyle defeated Steelix.[3]
