Before his battle against Ash, Tyson gave all his Pokémon a speech, saying that they needed to give their best to defeat Ash's Pokémon, and all his Pokémon started to train for the battle.[1]
After his Sceptile was defeated in Hoenn League semi-finals, Tyson sent Shifty to battle Ash's Torkoal. Torkoal fired Flamethrower, which Shifty evaded, and went to use Mega Kick. Torkoal was wounded by this attack, along with Shadow Ball. Shifty evaded another Flamethrower, so Torkoal jumped and tackled Shifty to the ground, defeating it.[2]
