Bond Phenomenon: Difference between revisions

Ash and his Greninja have perfected the transformation

The Bond Phenomenon (Japanese: キズナ現象 Bond Phenomenon) is a transformation affecting Pokémon that was introduced in Pokémon the Series: XY. It is said to have some connection to the Pokémon's hidden potential, similar to Mega Evolution and Primal Reversion.

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, whose alternate form is referred to as Ash-Greninja (Japanese: サトシゲッコウガ Satoshi Gekkouga). 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, which it can use in battle to great effect.

Main article: Greninja (Pokémon) → Form data

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 into Ash-Greninja after the opposing Pokémon has fainted and increases the power of Water Shuriken by approximately 33% (or more accurately, by a factor of 5448/4096). In addition, the base Battle Bond Greninja, before transforming, are treated as an alternate form separate from Greninja with Torrent or Protean. As of Pokémon Scarlet and Violet, Battle Bond no longer transforms Greninja to Ash-Greninja, currently making the form exclusive to Generation VII.

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

In the Pokémon 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.

Bond Phenomenon first appeared in The Legend of the Ninja Hero! , in which a Greninja in its Battle Bond form, is shown on a shrine in the Ninja Village.

Bond Phenomenon makes its first proper appearance 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 Catching the Aura of Fate!, Ash described that his ability to become one with Greninja felt similar to Lucario's Aura.

Possibly due to Greninja no longer transforming into Ash-Greninja in the then-upcoming Pokémon Scarlet and Violet, flashbacks to scenes that featured Ash-Greninja are changed to feature regular Greninja instead
