Bond Phenomenon

Ash and his Greninja have perfected the transformation

Bond Phenomenon (Japanese: キズナ現象 Bond Phenomenon) is a transformation affecting Pokémon that was introduced in the XY series. It is said to have some connection to the Pokémon's hidden potential.

Unlike Mega Evolution or Primal Reversion, the transformation does not require any specific items for either the Trainer or the Pokémon, though in the games it requires the ability Battle Bond. So far, the only known Pokémon to have this transformation is Greninja. In this form, the strength of Greninja's legs are superior to that of an ordinary Greninja. Additionally, it gains the ability to form large-sized Water Shurikens on its back.

In the games

Bond Phenomenon made its core series debut in the form of a Greninja that can be transferred to Pokémon Sun and Moon from the Special Demo Version. This unique Greninja possesses the Battle Bond Ability, which triggers the transformation after the opposing Pokémon has fainted and increases the power of Water Shuriken. This alternate form is called Ash-Greninja (Japanese: サトシゲッコウガ Satoshi Gekkouga). In addtion, the base Battle Bond Greninja, before transforming, are treated as an alternate form separate from Greninja with Torrent or Protean.

In the anime

Depiction from the Ninja Village of a Greninja who achieved the transformation

In the Pokémon anime, Bond Phenomenon first appeared in A Festival of Decisions!, in which Ash's Frogadier evolved into Greninja and assumed the Ash-Greninja form. However, the transformation would not be addressed by name until Kalos League Passion with a Certain Flare!, in which Professor Sycamore, after researching the matter, reported his results to Ash and his friends.

In the anime, Bond Phenomenon may be achieved when the trust between the Trainer and the Pokémon reaches maximum. While a Pokémon and Trainer are using this form, the Trainer shares the Pokémon's pain in the same place the Pokémon was dealt damage. The Trainer can also share the Pokémon's point of view. If the form is not mastered, the Trainer and Pokémon can pass out from exhaustion.
