Luke's Zorua helps him by transforming into characters for his movies by using its Illusion ability.
Ash Ketchum first encountered
Luke's Zorua just after he finished watching the trailer for "Miracle Fighter the Movie Part 24: The Mystery of the Miracle Shooter" and he turned around to see the Miracle Fighter right behind him.
Luke's Zorua then transformed back into its normal Zorua state and
Ash Ketchum thought about catching it until
Luke came running saying it was his Zorua.
Zorua was mad at
Luke because she only wanted to play the role of Princess Julia in the movie and not all the other cast members. Once
Cilan and his friends figured that out, they decided to help
Luke with the movie which made
Luke's Zorua happy.
Luke met his Zorua while helping out
Mr. Matthews with the projection machines. Every movie, Zorua would transform into the main heroine and watch the movie. Eventually
Luke figured out that it was Zorua transforming and then asked Zorua if it wanted to help him with a movie he was making. From then on, Zorua became
Luke's partner in making productions.
