Greninja bounces upwards after connecting with his diving down aerial. Use this to land multiple attacks. It meteor smashes when sweetspotted. Charge and release the Water Shuriken to push back opponents while hitting them multiple times. Charge Shadow Sneak to travel a greater distance in whichever direction you choose. Hold the Control Stick in the direction you're appearing to do an kick upon reappearing, and hold in the opposite direction to do a stronger back kick upon reappearing. Propel Greninja with Hydro Pump in two different directions or in a single direction covering a greater distance. After using Substitute, control the direction Greninja reappears for a counterattack with the Control Stick. For his Final Smash, Greninja catapults frontal foes with Mat Block, then repeatedly slashes them in the air before spiking them downwards.
