Secret Ninja Attack

Night Slash is Greninja's Final Smash in Super Smash Bros. 3DS/Wii U. Upon striking his target, the two rise into the air and the screen darkens as Greninja unleashes a flurry of attacks before dealing a final blow. In April's Nintendo Direct, Greninja was shown doing this in front of a moon, but it is unknown if the moon appears every time.

This move bears numerous similarities to Ike's Great Aether, and may be a sign that the unconfirmed veteran is not returning.
