There are many benefits to controlling the Kyuubi
Naruto will more then likely be able to have high speed regeneration
Kisame was able to heal from KB's lariat through Samehada's chakra
Naruto will be able to increase a duration of SM
He will have to draw in more natural enerhy to compensate for the fox's chakra
Naruto may possibly learn the secrets of Madara
The fox would be the most useful source of information on Madara
Naruto will have incread speed, stamina, and resilince(sp?)
As shown in previous mangas while Naruto is in the fox's cloak he has increased abilities
This also leads us to beleive that his speed should be increased exponentially by stacking with SM
Working with the fox should also be a counter to Tskuyomi
KB has shown to be able to break free of Tsukuyomi with the help of the Hachibi
Naruto's training speed should also increase
With a large increase in chakra Naruto can make more clones, more clones=increased training speed
He would also have is own ultimate defense
Nothing yet has been shown to penetrate the Kyuubis's Cloak, not Orochimaru's Kusanagi nor Chibaku Tensei
That's all for now
