Well, his Zorua is like the ones that I mentioned before, in that it has the ability to change it's appearance to look like any Pokemon, or even any human it wants. Luke and his Zorua often do this for movies that they make, since Luke is an aspiring film-maker. [In fact, we've been in two of his movies!] So Zorua can play as the characters in the movies he makes...though, his Zorua's tastes are that it only likes to change it's appearances into female humans or Pokemon. Also, unlike Ditto who can copy the movesets of Pokemon that they transform into, Zoruas in general don't copy the same moves in battles.
