Rasengan

thumb|The Rasengan's colour in Naruto: Colour Edition.

• The colouring of the standard Rasengan varies throughout the manga. For example, it is yellow on the cover of volume 52, blue on the cover of volume 67, and orange on the cover of Weekly Shōnen Jump #35 (2005).
  ** The anime is more consistent about depicting the Rasengan as blue, with the exception of The Last: Naruto the Movie, which depicts it as orange.

• While Minato intended to pass this technique on to Kushina, it is unknown if he succeeded.

• In the anime, if used underwater, the rotation force of the Rasengan is capable of creating a whirlpool.

• The anime shows Naruto being able to throw the Rasengan, something that is later established to require special training.

• Katasuke uses this technique through his Shinobi Gauntlet.

• In Naruto: Ultimate Ninja 3, Jiraiya spews fire onto his Rasengan, creating the Fire Release: Great Flame Rasengan.

• Jump Super Stars is one of the few video games where Part I Naruto is able to access his non-clone-refined version of his Rasengan, dubbed as Rasengan: In Training (螺旋丸・修行中, Rasengan: Shugyōchū).
  ** Likewise also in both the first 2 Uzumaki Chronicles games, Naruto can perform a version of the Rasengan without a clone enhancing it (holding down the input in the second game does involve the clone and turns it into a "True Rasengan/Spiralling Sphere" with merely an increased damage multiplier and hitbox duration).
  *** The video game Battle Stadium D.O.N. also curiously does not have a clone assist Naruto in the formation of the technique.

• The Rasengan's appearance resembles Kūatsuken, a technique from the Ninku series.
