Template:Infobox Final Smash SSB4 Greninja's Final Smash, known in Japan as Mysterious Ninja[1], does not currently have a known English name. In this Final Smash, Greninja sends one or more foes airborne by hitting them with a tatami, then slashes away at its opponent in front of the moon. It then readies a final blow to send the foe flying.
Origin
Greninja activates this move by striking downward at a tatami, a type of mat, to flip it upward and hit opponents, referencing Mat Block (known in Japan as Tatami Flip), one of its signature moves in the Pokémon games, the other being Water Shuriken. Mat Block possesses the ability to defend the user's side of the field from all attacks used after it; however, unlike other protective moves, it does not possess increased priority.
The full moon behind the attack appears to be a reference to bulbapedia:Night Slash, which Greninja learns naturally. The move possesses an increased critical hit rate.
