Yes to N in Gen 6. I really like how much depth and development they've given to him. After all of the one dimensional villains they've had in Pokemon, it's really nice to have a villain that has depth and changes throughout the story. He's definitely the most interesting and deep character in the Pokemon series.

...and to think some people think Blue in Gen 1 is a better villain...

Also:



Its Japanese name is Ninfia and its type is unknown, but I'm guessing it's a new type. Light maybe? I suspect Xerneas is also light type.
