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, or extend then expand to hit and reduce whatever it touches to dust. According to Hiruzen Sarutobi the technique is similar to Dust Release, but on a far greater level in terms of shape transformation, allowing it to be constantly used for either offence or defence. Hiruzen also notes that it is beyond both kekkei genkai and kekkei tōta, being comprised of at least four different nature transformations.

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.
