Rasengan
Use Naruto's Rasengan to attack the Master Puppet. This attack makes Naruto invulnerable for a brief moment so the other attacking puppets won't be able to hurt him. After hitting the Master Puppet with a few Rasengans, four spirit orbs will appear.
Spirit Orbs
Focus your attacks on the four glowing spirit orbs that are located on the platforms. Once you've dealt enough damage to the orbs, they stop glowing, and the Master Puppet is left immobilized for a brief period.
Direct Attack
Attack the Master Puppet directly while it's immobilized. After depleting its first three health bars, its mask will change, and it will gain more powerful attacks.
Shadow Clones
To avoid getting hit by the Master Puppet, attack indirectly with Naruto's shadow clones. When its last health bar is almost depleted, the Master Puppet will regenerate all of its health bars and begin using a deadly force field attack.
Dodge and Counter
Avoid getting hit by the force field and continue attacking with Naruto's shadow clones to deplete two of the Master Puppet's health bars.
Nine Tails
Use Naruto's Nine Tails ability to power up so you can deal out more damage. While using the Nine Tails ability, use a combination of shadow clones and direct attacks to deplete the Master Puppet's last health bar and finish it off for good.
