Biography[]
Levi had Steelix use Stealth Rock in tandem with Cherie's Manectric's Electric Terrain to trap Ash and Volcanion. It was transported back to the ship through Levi's Alakazam's Psychic.
Steelix was sent out along with the other Pokémon by Levi and Cherie, but, like all of Alva, Levi, and Cherie's Pokémon, Steelix suffered from the painful Mega Wave transformation, and was used to battle the Pokémon from Ash and co. Later it tried to attack Ash's Noivern and Greninja and was attacked by Volcanion when it fell from the sky and crashed into it.
After Alva's Mega Wave Crystal was shattered by Ash, Steelix reverted back to normal along with the other Pokémon, and it managed to escape the flying kingdom along with the other Pokémon with Levi's Alakazam's Psychic.
