Focus on getting Four out of the picture first, as his ground attacks can be brutal. Four Tails hits hard from the ground, while Seven Tails launches a full-on airborne attack. This is the most difficult (and frustrating) portion of this fight. Unload on him until he calls out the Four and Seven Tails. With both Tailed Beasts sidelined, Tobi will jump back in for some more Mob Battle action.
When Five is out of the picture, hit Six with ground combos until it goes down. Take out Five Tails first, as Six is rather stationary just avoid the stream of bubbles it will send out. Chakra Dash from above to land as many air combos as you can, and call Eight Tails as soon as his gauge fills. The same strategy from the first Tailed Beast battle. He will call in the Five and Six Tails before his first energy bar is depleted. This confrontation should give you absolutely no trouble: Use Substitution Jutsu when necessary to get behind Tobi and unload with everything you’ve got. When the action resumes, Naruto will square off in a one-on-one Mob Battle against Tobi. Take a breath and get ready for the next part of this battle. Taking them down will lead into a QTE sequence that will lead into a cutscene. When he’s out of the picture, attack Three Tails with ground combos. Try to take out the Two Tails first, as he has a charge move that does a lot of damage. Keep moving use a mid-air Chakra Dash to hit catch up to the beasts and hit them with a barrage of combos. Eight Tails will be available for support, so call him in as soon as you can. The first part of this confrontation pits Naruto against the Two Tails and the Three Tails - at the same time. This is probably the hardest fight in the entire game, and having no opportunities to restore any health lost during the previous skirmish only adds to that.
