Greninja using Mat Block before his Final Smash

Secret Ninja Attack (しのびのひおうぎ Shinobi no Hi Ougi?, lit. "Shinobi's Secret Finishing Technique) is Greninja's Final Smash.

Greninja will put a mat underneath the opponents in front of it and smack it like a lever, sending the opponents into the air as the screen darkens and a moon appears. There, a silhouette of Greninja will fly around rapidly dealing quick strikes before dealing a final blow. The screen will focus on Greninja floating in the air for the next few seconds, leaving the target to be KO'd offscreen.

In Super Smash Bros. Ultimate, Greninja's Final Smash returns, but the only difference is that Greninja transforms into Ash-Greninja before performing said Final Smash.


  • This Final Smash was initially erroneously referred to as "Night Slash". However, Greninja's Final Smash appears to have elements of both Night Slash and Mat Block in it.
  • Greninja's trapping mat that the Pokemon uses to trap his opponents is actually one of his signature moves; called Mat Block from Pokemon X and Y.
  • The Final Smash is similar to Spider-Man's Hyper Combo in Marvel vs Capcom 3 called Maximum Spider, D1 also said the name when a Greninja player used the Final Smash against two players in the Super Smash Bros. Invitational tournament.
