Quoted By:
>Ash's Greninja was able to transform into Ash-Greninja solely based on it's bond with it's trainer. This bond is theoretically stronger than Ash's relationship with Pikachu, Charizard, Sceptile, Butterfree, Krokorok or any other pokemon having a strong bond with Ash. Despite all of this, Ash still releases Greninja, making it achievements worthless.
