I haven't heard of the fire rasengan... Only of the regular one, and Rasen-Shuriken. And Wind shuriken (which is rasen-shuriken, basically). They're both formed like a huge demon-wind shuriken out of chakra and thrown
I don't think so, he uses odama rasengan although it takes place where naruto uses the wind rasengan on kakuzu he dos learn it it is so powerful that its stronger then kakashi but not as strong as wind shiriken
Rasengan was ment to be mixed with elemental chakra, but Fourth wasen't abel to do it before he dies. Neither was Kakashi or Jiraiya, so Kakashi made Chidori instead. And since Kakashi has talent for lightning, he choosed to make a lightning jutsu
Jirayia, Yondaime (4th hokage), naruto,tsunade,and kakashi. Hope this helps
The fourth hokage (yondaime). He thought jiraiya and kakashi hatake and jiraiya then teaches naruto.
Yes, he does
yes he does
You can not have rasengan as a customizable jutsu. You can learn chidori which is almost the same thing.
Yes he can. It was shown somewhere in episodes 74 - 76. I would guess that he is able to preform Rasengan because he either copied/learned it from Yondaime Hokage(4th hokage) or Jiraiya.
Naruto Shippuden episode 15
Well, it depends on what kind of Rasengan. If it's the Rasenshuriken, then he can only use it twice, but if you're talking about the regular Rasengan, then it has no specified limit as to how many times he can use it.
Kakashi reveals that the Rasengan is an incomplete jutsu as he is not able to combine his own elemental chakra affinity into it, just as it's creator, the Fourth Hokage couldn't do. He then presumes that Naruto might be the first one to be able to do so. Kakashi reminds Narutothat creating a technique requires combining nature transformation with shape transformation. By completing hisWind Release training he has the former, and since he can already perform the Rasengan he has the latter. Naruto concludes that creating a new technique will be easy since he has already mastered both components, but Kakashi corrects him by showing that he can also use the Rasengan. Combining nature transformation with the Rasengan was too difficult for Kakashi and the Rasengan's creator, the Fourth Hokage. Kakashi is confident that Naruto will succeed where they failed. naruto shippuden #75+76
Rock Lee can only do Taijutsu. The techniques he cannot do is Ninjutsu and Genjutsu. Ninjutsu is ANY justu that uses chakra. In order to made Rasengan you need to spin chakra.To answer your question: No, Rock Lee cannot learn Rasengan.
