Custom Pokemon?

    Between all the hype of the new Zygrade forms, the real life Pokemon Gym, and future Pokemon distribution events, there is another piece of news that is getting less attention than it should.  The Ash-Greninja.

    Revealed in the same CoroCoro Magazine alongside the Zygrade Forms, The Ash-Greninja appears to be a Greninja that resembles Ash.  It has been commented on through the Pokemon site: 

"Ash's Greninja takes on a mysterious new appearance in the latest season! Ash-Greninja is the form that Greninja takes when the bond between it and Ash is raised to the limit. The strength of their bond changes Greninja's appearance, and it takes on the characteristic look of Ash's attire. This phenomenon is also said to have happened just once several hundred years ago in the Kalos region, but it remains shrouded in mystery."

So what does this mean? Well first off this is something that appears in the Anime. It seems to happen when a Pokemon and their trainer's bond increases. As for the "It happened just once several hundred years ago" part many fans can come to one simple deduction: 

   Yupp, you guessed it this is the cutscene from Pokemon X and Y with the giant names AZ and his oddly colored Floette. This Floette is different colors than most other Floettes and had a very strong connection with it's trainer.

This leaves another question? Is this something we will also see in a video game?

In the remakes of Ruby and Sapphire they has a cosplay Pikachu in which you could dress up your Pikachu. In X and Y they had the story of AZ and his Floette.  So I assume this is something we may be able to do in a future main series Pokemon game, maybe the rumored Pokemon Z.  I feel it may be limited to your starter Pokemon or something along those lines. Another complication is in X and Y you were able to change your player's outfit, we would have to see if this would still be an option and if so how will it affect the appearance of your Pokemon.
