After obtaining a Zorua from one of the former Seven Sages, you can encounter Pokemon N released in the wild. They will have a special animation when you encounter them, so you probably won't miss them. Instead of the text saying wild <Pokemon> appeared! It will say wild <Pokemon> appeared?! These Pokemon can never be shiny, and have set IVs. They will always have N's ID number as well. You can obtain 14 of N's Pokemon in the wild.
What did you think of this concept? Did you capture N's Pokemon? I did do this, yes, and I thought this was a cool concept. I wish they'd bring this back at some point? Imagine how many Pokemon in the wild used to belong to another trainer.
I got the Zorua, who I used on my team. :) I remember that when I first saw the green effect, I didn't know what it was and assumed that it always happened when you sent out a Zoroark without it being under an illusion. Haha.
N's Pokemon are amazing for obtaining a certain Hidden Power via breeding. :]
There still a few of N's Pokemon I haven't captured but I thought it was a neat concept. A shame the unique shine doesn't transfer over to newer gens.
