Template:Infobox Final Smash SSB4 Secret Ninja Attack (しのびのひおうぎ, Secret Ninja Technique), is Greninja's Final Smash. In this Final Smash, Greninja sends one or more foes airborne by using Mat Block: hitting them with a tatami, then slashes away at its opponent in front of the moon. Greninja then readies a final blow to send the foe flying.

The Final Smash deals a total of 52% damage: 2% if opponent(s) are caught by the Mat Block, 5% for the Mat Block flip, 2% for each rapid slash, and 15% for the final blow.

Trophy Description

Secret Ninja Attack Trophy in Super Smash Bros. for Wii U.

In Greninja's Final Smash, it uses its Mat Block move to flip opponents into the air. It then slices them repeatedly in front of the bright moon before smacking them back to the ground and launching them. The initial Mat Block flip doesn't have much range, but should it hit home, the rest of the attack is unavoidable.

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, and thus will fail if used last in the turn. It is also only able to be used the first turn after Greninja enters the field; at all other times, it will fail.
