Greninja

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 Pokémon media. It is the final evolution of Froakie, the Water-type starter Pokémon 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. Ash-Greninja has increased speed. Categorized as the "Ninja Pokémon", Greninja is a Water- and Dark-type Pokémon who is a frog-like master of swiftness and stealth. It appeared prominently in the XYZ series of the Pokémon anime as one of Ash Ketchum's primary Pokémon, 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 Pokémon 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 Pokémon series' five representatives, and was integrated into manga such as Pokémon Adventures. Greninja also appeared in Super Smash Bros. Ultimate on the Nintendo Switch. Greninja has been met with a very positive reception, quickly becoming one of the most popular Pokémon of the sixth generation, and of all time in the 2020 vote with 140559 votes, because of its endearing design and strength in competitive play. Greninja was not made available in or transferable to any Generation VIII Pokémon main series video games until in Generation IX Pokémon main series video games. However, its reappearance in Pokémon Scarlet and Violet received a more polarising response, due to the alterations made to the ability, Protean, as well as its special ability Battle Bond, which can no longer change Greninja into its Ash-Greninja form. Its popularity has resulted in its integration into various merchandising and promotions of the Pokémon franchise. Concept and characteristics 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 frogs. 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.
