TheSooped wrote: Especialy when his father is a master over chakra. I fixed that for you. With the Six Paths powers, Naruto has full control over all Shape and Nature transformations. He is the first, in fact, to combine multiple elements in a jutsu that does not involve mixing them. E.g. Lava Rasenshuriken combines 3 natures yet has 2 of them separate.

However as i mentioned elsewhere (maybe here too?) the recent Character poster suggests it's all about Boruto surpassing Naruto at the same age, not Narusus and Sasifer
