Editing Secret Ninja Attack

In this Final Smash, [[Greninja]] sends one or more foes airborne by using {{iw|bulbapedia|Mat Block|move}}: hitting them with a {{s|wikipedia|tatami}}, then overwhelms its opponent with slashes, kicks, and palm strikes in front of the moon. Greninja then readies a final blow to [[meteor smash]] the foe.  

It is similar to Ike's [[Great Aether]].

It then slices them repeatedly in front of the bright moon before smacking them back down 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.

It then slices them repeatedly in front of the shining moon, before smacking them down to the ground so hard they get launched.

Greninja activates this move by striking downward at a tatami, a type of mat, to flip it upward and hit opponents, referencing {{iw|bulbapedia|Mat Block|move}} (known in Japan as Tatami Flip), formerly one of its {{iw|bulbapedia|signature move}}s in the ''Pokémon'' games. 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. While not named after it, the move's overall aesthetics share thematic similarities with {{iw|bulbapedia|Night Slash|move}}, a move Greninja can learn by leveling up in the games.  

[[File:Ash-GreninjaDEMO.jpg|thumb|150px|Greninja transforming into Ash-Greninja in the ''Pokémon Sun and Pokémon Moon Special Demo Version''.]]

In the Pokémon anime, upon his final evolution, {{iw|bulbapedia|Ash Ketchum}}'s [[bulbapedia:Ash's Greninja|Greninja]] obtained a unique ability called {{iw|bulbapedia|Bond Phenomenon}}. It is similar to Mega Evolution but relies on being in sync with Ash rather than a Mega Stone. This transformation caused Greninja to temporarily take on a design based on Ash and his Kalos outfit, as well as producing a psychic bond with Ash.  

The transformation later appeared in the main series games with a special Greninja with {{iw|bulbapedia|Battle Bond}} only obtainable through the [[bulbapedia:Pokémon Sun and Pokémon Moon Special Demo Version|''Sun'' and ''Moon'' demo]], where the transformation would activate upon defeating an opponent directly. Ash-Greninja has higher base stats than regular Greninja and if Ash-Greninja uses Water Shuriken, the move's power becomes 20 (rather than the usual 15) and it always hits three times.  The transformation would later be removed in ''Pokémon Scarlet and Violet'' with Battle Bond only boosting Greninja's attack, special attack and speed. Ash-Greninja is referenced in {{iw|bulbapedia|Nemona}}'s house as a painting however.
