A ton of people have wondered what the fist bump within the few new Naruto Shippuden episodes and Manga chapters mean. A lot of people have mentioned that it’s a sign of respect showing that one trusts another.
I personally think that within the Naruto Anime and Manga, there are plenty of explanation and different types of fist bumps, they may all be just a fist bump but they represent a different kind of relationship each time.
When Son Goku, the Four-Tail, asks Naruto to put his hand out, Naruto asks Son what it is, as he wonders what he’s about to get. Son Goku, has a lot of respect by now as he had removed the black stake which held the body of Roshi and Son Goku together. Son knows that Tobi, the masked man, will be taking Son Goku back using his mysterious technique so he gives Naruto a last-minute Fist Bump to show the that he has a lot of respect for what he’s done. It’s still not confirmed but it here Son Goku could have transferred some of his powered to Naruto.
Within Naruto 570, we see Kurama, Nine-Tails, ask Naruto to Fist Bump him. Kurama puts his hands out and says “Meld Your Chakra With Mine…”, as seen in the image above. Before Kurama always kept to himself, he never talked to Naruto or even shared any of his powers with Naruto. Here Kurama saw how Son Goku trusted Naruto within a few minutes due as seen by the Fist Bump, while Kurama has been with Naruto all of his life and never trusted him.
At the point of the Fist Bump, both Naruto and Kurama had concentrated a little harder than usual, Naruto returns to the fight as thought his strength has been restored. It is as thought that fist bump was a little more than just a fist bump, more like a transfer of energy. We saw a little while ago when Naruto and Kurama fought so Naruto could obtain his Chakra Mode form. The way Naruto gained power from Kurama could have been the same here too.
After this point, Naruto had opened his seal to let Kurama out! You can see the post here.
We saw a lot in this chapter! But all the action will be within the next Naruto 571 chapter! I definitely cannot wait to see Tobi’s and Killer Bee’s face when they find out Naruto has teamed up with Kurama, not as a Monster-Fox, but as a team-mate from the Leaf Village!
