Okay, so here is what we know. 1. There are two forms of Chakra Manipulation. Altering Form, and altering Nature. 2. Rasengan alters it's "form" into a massive chakra spiral. 3. Knowing this, Rasengan is an incomplete jutsu, since it was originally intended to be combined with Chakra altered into an element such as fire, wind, lightning, earth, or water. Now we know that Naruto is attempting to complete Rasengan, shown here. We see the effects here caused a massive vortex. Notice how Naqruto was trying to force wind chakra into the Rasengan. Now Kakashi uses Chidori as an example of manipulating "nature" Of course you may be wondering why the heck I brought up Chidori in a Rasengan Topic and how it is completed. So now I show you an example of what happened in VoTE. Spoiler: VoTE Event NOw when we see Chidori and Rasengan FORCED together, wouldn't it technically force both nature-manipulated and form-manipulated chakra into one complete combination of both? The reaction was similar. when Naruto tried inserting wind element into Rasengan, he was blown away, and lightning, it blasted both Sasuke and Naruto away. Could it be possible that the clash between Chidori and Rasengan at VoTE be a clue as to what the complete Rasengan would look like? After all, we know that Kishi loves to forshadow things, such as Team 7's Sannin thing. Anyways, this is just something that I had in mind, and I would like to know what you guys think of it.
