is a Pokémon species in Nintendo and Game Freak's Pokémon franchise, introduced in Pokémon X and Pokémon Y, that has since appeared across a wide variety of Pokemon media. It is the final evolution of Froakie, the Water-type starter Pokemon of X and Y, with either the ability 'Torrent' or 'Protean', with 'Battle Bond' as an event ability, enabling it to become Ash-Greninja, and the immediate evolution of Frogadier. Categorized as the "Ninja Pokémon", Greninja is a Water- and Dark-type Pokemon who is a frog-like master of swiftness and stealth.

It appeared prominently in the XY series of the Pokémon anime as one of Ash Ketchum's primary Pokemon, voiced by Yūji Ueda. This Greninja used its bond with Ash to transform into a unique and powerful form, Ash-Greninja, which was later released to the games as an empowered form of Greninja accessible to players of the Pokemon Sun and Moon Special Demo Version. Greninja was introduced as a playable fighter to the Super Smash Bros. franchise with Super Smash Bros. for Nintendo 3DS and Wii U as one of the Pokemon series' five representatives, and was integrated into manga such as Pokémon Adventures.

Greninja has been met with a very positive reception, quickly becoming one of the most popular Pokémon of the sixth generation because of its endearing design and strength in competitive play. Its popularity has resulted in its integration into various merchandising and promotions of the Pokémon franchise.

Greninja is a streamlined frog-like creature with dark blue skin and a beige underbelly, with long limbs and thin, slender physique particularly reminiscent of tree frog. What resembles a pink scarf is actually its prehensile tongue wrapped around its head. Two long, ear-like protrusions extend from both sides of its head and connect with a smaller horn-like structure in the middle by azure blue-colored webbing. Spots of the same azure coloring can be found on each thick thigh, arguably resembling ninja stars or battle scars along with a stubby tail that wraps inwards resembling a phallus. Much like a frog, Greninja has webbed feet, wall-clinging suction cups on each digit, and powerful hind legs. It shoots streams of compressed ejaculate patterns from its palms. A large bubble can be found on each limb. A bipedal creature, Greninja can comfortably stand on its hind legs, but leans on one of its front limbs in a crouching stance when in battle. When at rest its eyes are white with hyphen-shaped pupils, but when engaged they gain red, oval-shapes irises, white pupils, and a narrow gaze. It only weighs 88.2 lbs. (40 kg), but is still quite tall at 4' 11" (1.5 m).

Greninja has not been a contender in any CBUB matches.
