Greninja (ゲッコウガ, Gekkōga) is a playable veteran in Super Smash Bros. Ultimate. It was confirmed when Pokken Tournament DX was released. Greninja is voiced by Billy Bob Thompson in English and Yūji Ueda in Japanese. It also has other voice actors for other regions.
Greninja now uses it's appearance when it is in it's "Ash-Greninja" form, popularized by the Pokemon: XYZ anime. Due to this change, Greninja has changed animations and his Water Shuriken is changed.
