Actually, it's not a Mega, it's revealed as a new type of evolution, and an odd phenomenon. Pokemon.com describes it as, "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."

This transformation may be perminant, and would definetly be an important factor in this battle.
