Truth Seeking Balls

When an individual enters a Six Paths Senjutsu state or having achieved the Tenseigan, these orbs appear and generally float in a circular formation behind the user's back. By utilising the power of all of creation (森羅万象, Shinra Banshō; Literally meaning "All-Covering Forests and Ten Thousand Things"), the balls can be shaped into a variety of forms, and the many natures comprising them can be combined to produce various effects.[1] Obito Uchiha usually shaped the balls by having them pierce through holes that temporarily formed in his hands,[5] whereas other users forego this process and simply mould them.[6] The balls can serve various offensive, defensive, and supplementary purposes, such as wrapping around the user to act as a defensive shield,[7] or launching toward targets as high-speed projectiles.[8] They are also capable of causing massive explosions by rapidly expanding in size.[9] Each orb is about the size of a fist and hides within enough power to completely obliterate a forest.[1]

According to Minato Namikaze, the balls are a type of technique that is always on standby, rather than activating from nothing.[10] Hiruzen Sarutobi stated that this technique uses attacks that instantly turn their target to dust, similar to Dust Release, but the technique's fluid nature allows it to serve both offensive and defensive purposes, and it can be maintained. Hiruzen also noted that, since the substance is a combination of more than three nature transformations, it is neither a kekkei genkai nor kekkei tōta, but greater than both.[5] Tobirama Senju analysed that this technique can utilise Yin–Yang Release to nullify all ninjutsu the balls touch. As a result, any damage done by this technique to a reincarnated individual who can usually regenerate infinitely cannot be repaired, and said individual could die.[4] However, Obito's Truth-Seeking Balls did not nullify ninjutsu prior to him gaining control over the Ten-Tails' power.[5] The balls can also quickly heal severe injuries through contact,[11] glowing red while doing so in the anime.[12]

The black substance that comprises the balls is highly durable, only taking damage from powerful techniques such as the Evening Elephant and a senjutsu-enhanced Tailed Beast Ball.[13] When Obito produced chakra receivers to use the Six Red Yang Formation, the ball behind his right hand emitted the same red chakra as the receivers and subsequently disappeared.[14] The balls can also be used to create the legendary Sword of Nunoboko.[15]
