Prior to BW040: Movie Time! Zorua in "The Legend of the Pokemon Knight"!
Luke's Zorua is Luke's main Pokémon and it has often appeared outside of its Poké Ball. It is thought to be female because it has a preference to transform into female individuals, most notably Princess Julia in Luke's movie.
Zorua has a tendency to transform into other people (like Iris and Georgia) in order to purposefully make them angry, much like the Zorua in the movie "Pokemon Movie 13 - Zoroark Master of Ilusions" did to Dawn.
Given that Zorua don't learn Night Daze until level 57, it can be assumed that this Zorua is quite powerful.
