So does the Four-Tails pictured above for that matter. I’m a little thrown off by how the Four-Tails is named after the legendary monkey king “Son Goku” though, simply because the Third Hokage’s summon, Enma, already fits his description. Enma even transformed into the staff that Son Goku carries. Not that I mind or anything of course, as this was merely an observation.
As for the Nine-Tails, it’s kind of nice to have a name to call him by now: Kurama (the tsundere demon fox). While it’s probably a little too predictable for most people’s tastes, I actually like the idea that Naruto will get along with Kurama someday, just like B does with the Eight-Tails. B’s a force to be reckoned with because he can let the Eight-Tails take control of his body and transform into his beast form, so the prospect of seeing Naruto do the same with Kurama is intriguing to say the least — especially if it’s defending Konoha instead of attacking it. Whether or not this happens will depend on Kurama though. If Naruto can bring him around like all the other people he’s come across, there’s a good chance he’ll let Kurama out of his cage so that he can unleash his full power.
For now, it looks like Kurama’s going to stay put and see how things work out between Naruto and Son Goku. If the Four-Tails is freed from his chains, I wonder if that means Tobi loses his chakra altogether — effectively undoing Akatsuki’s sealing technique. However, he wouldn’t have a Jinchuuriki anymore, so would he roam free in his full form? I really don’t see that happening.
