Greninja is a Water- and Dark-type Ninja Pokémon native to the Kalos region. It evolves from the starter Pokémon Froakie, who is available for new trainers to choose along with Fennekin and Chespin.
How to unlock Greninja?
With a diverse movepool and the Hidden Ability Protean, it has found a spot among the greats in competitive Pokémon battling. It’s also one of the only known Pokémon to have two signature moves: Water Shuriken and Mat Block, both of which it puts to use in this game.
Being a Water-type Pokémon, it naturally uses water for most of its attacks. Its slick Shadow Sneak maneuver and countering Substitute move coupled with its high aerial mobility make it a rather agile and devious fighter.
