Truth-Seeking Ball

Upon becoming the Ten-Tails' jinchūriki, Obito Uchiha is able to create small orbs of a mysterious black chakra over his hands. He can have them pierce through his palms to become blades, wrap around him to act as a defensive shield, extend then to hit the enemy or even launch them and cause them to expand and contract and reduce whatever it touches to dust. According to Hiruzen Sarutobi, the technique is similar to the Dust Release, but on a far greater level in terms of shape transformation, allowing it to be constantly used for either offence or defence, though it cannot keep its shape for very long. Hiruzen also notes that it is beyond both kekkei genkai and kekkei tōta, being comprised of at least four different nature transformations.

After gaining control of the Ten-Tails, and assuming his new transformation, Obito becomes capable of transforming the orbs into complete structures, such as a monk's staff. He can also attach the ball to other objects and detonate it at will.

Shape Variants
This technique can be manipulated into a variety of shapes for various purposes. According to Hiruzen, there is a time limit for each different shape transformation performed.
