Truth-Seeking Ball

Upon becoming the Ten-Tails' jinchūriki, Obito Uchiha is able to create small orbs of 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 his targets to dust; even strong defences, such as Susanoo. According to Hiruzen Sarutobi, the technique is similar to Ōnoki's Dust Release, but on a far greater level in terms of shape transformation. Hiruzen also notes that Obito uses at least four different nature transformations when performing this technique, but which ones are unknown.
