Zapdos appeared in the second feature length Pokémon movie, The Power of One. Its voice actor in both Japanese and English is Katsuyuki Konishi.
Zapdos, as depicted in an ancient legend, is the titan of lightning. Lawrence III was trying to capture the three legendary birds in order to lure out Lugia. After Moltres was captured, Zapdos claimed its island as its own territory (Which implies that the weather disruptions, while caused bu Lawrence III, was mainly caused by Territorial disputes). Lawrence captured Zapdos along with Ash, Misty, Tracey, Melody, Jessie, James, and Meowth. Zapdos was freed by Moltres and the two birds burst out of the palace.
In their rage, the three legendary birds began to battle. When Lugia rose up from the sea, Zapdos worked with the other birds to return Lugia back into the sea. Later, Lugia rose again out of the water without any of the birds noticing.
Lugia, with the help of Ash, silenced the battle between the birds and Zapdos returned to its island.
