[Luminion Lancer]

-You know I was starting to question the power of the new Rasengan. I mean, all it did was stop Kakuzu's attack and that was it, or so I thought. Notice how Kakuzu used both the Katon and Fuuton hearts together at once. What does that tell you? That's right, it means he was strenghtening the Katon jutsu with the Fuuton jutsu. Considering this I believe that the Yamato/Naruto combo jutsu wasn't specifically designed to attack, but rather defend. If the primary function of the Hurricane Maelstrom was to defend then it is plausible to believe that the attacking power of the Wind Rasengan was lowered greatly and was instead used as a support to give the Suiton Jutsu the necessary shape and defending power. Still, that would indicate that Naruto has the "know how" when it comes to designating the power output of his jutsu, something that seems a little too advanced for him. Then again we are talking about the #1 Ninja at surprising people.
