"Naruto Shippuden" is airing its last and final episode on Thursday, Sept. 29, and it is expected that the upcoming episode will be the most-action-packed the anime series will feature ever as Naruto and Sasuke try to outdo each other in their quest to prove their respective supremacy.

According to reports, the upcoming episode 476 of "Naruto Shippuden" will highlight the last and final showdown of force between Naruto and Sasuke. Allegedly, Sasuke will be bent on finishing Naruto and care less about the relationship he had with him.

Sasuke's desire to finish Naruto stems from his desire to create a perfect world that will be devoid of sufferings for him and Itachi. In order for him to achieve that goal, though, he needs to get rid of the five Kages, destroy all tailed beasts, and kill Naruto.

As Sasuke has already accomplished the two other things that he needed to do to fulfill his desire, the only hindrance to his goal now is Naruto. Hence, it is said that Sasuke will move heaven and earth just to put an end to Naruto as he brings his goal into completion.

With this, fans are now curious on who among the two will survive in their biggest clash ever. While there are some who believe that it will be Naruto who will emerge as the victor, there are also those who place their bet on Sasuke, much more that the latter has already demonstrated how powerful he can be with the use of his multi-sphered version of the Chibaku Tensei.

There are also those who believe that neither of the two will survive as both of them will perish. However, if the spin-off manga series "Boruto: Next Generation Naruto" is to be the basis, it's unlikely to be the case as both grew up to be the older versions of themselves, already have their respective families, and are friends.

Meanwhile, according other sources, although "Naruto Shippuden" episode 476 will feature the last and final battle between Naruto and Sasuke, it doesn't really mean that the anime series will already take a bow. Apart from the possibility of coming up with filler episodes, it is also said that it will also be replaced by the manga title "Naruto Hiden," which will feature more adventures of Naruto.
