Hmm, I wonder...
80% chance of beating him. 51% of that is because he's the main character and it's not a situation where the battle seems like it's actually someone else's time to shine ie him and Sasuke vs Orochimaru in the Forest of Death.
The other 29% is because the Kyuubi seemingly has something up his sleeve and is potentially about to give him insane level powers. My fingers are crossed for 4-6 tail mode but still in human form and the ability to do everything we've seen the Kyuubi do and Naruto do.
20% is missing because they showed that Sasuke is making his way to the battlefield and we don't really know what his gameplan is.
The apes are kinda angry and are thinking they want a planet all to themselves.
