-RASENGAN-

Created by the Fourth Hokage and taught to him by Jiraiya, the Rasengan is Naruto's second and strongest signature jutsu. While the Rasengan is a one handed technique, Naruto required the use of two to form it due to his poor chakra control, thus using a clone to form the "shell" of the sphere. Despite this, Naruto has used the Rasengan effectively in almost every one of his fights after mastering it. The Rasengan holds an advantage over its counterpart, the Chidori. The Rasengan only requires chakra control to form, while the Chidori uses so much chakra that it can only be used a few times a day. Naruto mastered the Rasengan to a degree that he can do it almost instantaneously. The Rasengan, like the Clone Technique, would be the base of several original jutsu created by Naruto, such as the Great Ball Rasengan, a larger version of the Rasengan, and after his wind training created the Wind Release: Rasengan and Wind Release: Rasenshuriken, and after his senjutsu training, the Sage Art: Great Ball Rasengan and Sage Technique: Rasenrengan. Due to the unique nature of the Rasengan in Naruto movies, Naruto creates a new type of Rasengan, often facilitated by a character in the movie, or a unique property present in the movie.
