Battle Bond

Introduced in Generation VII

Transforms this Pokémon into Ash-Greninja after fainting an opponent. Water Shuriken's power is 20 and always hits three times. This ability cannot be copied or replaced. This ability only takes effect for Greninja.

“When the Pokémon knocks out a target, its bond with its Trainer is strengthened, and its Attack, Sp. Atk, and Speed stats are boosted.”
