Secret Ninja Attack

Secret Ninja Attack is Greninja's Final Smash.

Overview
Greninja sends one or more foes airborne by using Mat Block: hitting them with a tatami, then overwhelms its opponent with slashes, kicks, and palm strikes in front of the moon. Greninja then readies a final blow to send the foe flying. Similar to Ike’s Great Aether.

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 attack, and 15% for the final blow.

In Super Smash Bros. Ultimate, Greninja transforms into Ash-Greninja for the Final Smash.
