Make your ultimate Rasengan (possible light spoilers)
If you haven't already found out, the Rasengan as we know it isn't complete (although other people might know what I'm talking about). The Rasengan was made by the Fourth Hokage to be fused with ones own elemental chakra* (that was the spoiler in case you are wondering, not really a spoiler, is it?) and you then make it your own (in Shippuuden, when Naruto fights Itachi [Yura] before he used Oodama Rasengan, he has a flashback of talking to Jiraiya and Jiraiya says that you are supposed to make Rasengan your own by adding your own elemental chakra and fighting style to it). That is what I want to hear, how you would make it your own.
