He tried again to capture Celebi without the use of his Dark Balls, but was defeated when Ash's Pikachu used Thunderbolt on his jetpack. He was captured and was most likely jailed at the end of the movie. His Pokémon were also seen released near the end, going back into the wild. In Team Rocket, Vicious is known as the Iron-Masked Marauder.
