Battle Bond (Japanese: きずなへんげ Bond Transformation) is an event-exclusive Ability introduced in Generation VII. It is the signature Ability of Greninja.



In battle

When a Greninja with Battle Bond directly causes another Pokémon (including allies) to faint by using a damaging move, unless this ends the battle, it will change into Ash-Greninja. After the battle, the Pokémon reverts to its original form.

Ash-Greninja has higher base stats than regular Greninja. If Ash-Greninja uses Water Shuriken, the move's power becomes 20 (rather than the usual 15) and it always hits three times. If a Pokémon transforms into Ash-Greninja, Battle Bond does not affect the transformed Pokémon's use of Water Shuriken.

Multiple Greninja can activate this Ability during the same battle. If Ash-Greninja faints in battle, it will revert to its original form, and that Greninja cannot change into Ash-Greninja again during the same battle even after being revived.

Gastro Acid, Worry Seed, Simple Beam, and Entrainment fail if the target has Battle Bond. Role Play and Skill Swap fail if either Pokémon has Battle Bond. Battle Bond cannot be copied by Trace, Power of Alchemy, or Receiver. Battle Bond cannot be replaced by Mummy or suppressed by Core Enforcer. If a Pokémon other than Greninja obtains Battle Bond with Imposter or Transform, the Pokémon cannot change form into Ash-Greninja even if it knocks out another Pokémon.

Outside of battle

Greninja with this Ability cannot breed nor be used in the Battle Spot if Special Pokémon are banned. However, it can be used in the Battle Tree.
