Having been the Kage of his village, Mū was an immensely powerful shinobi. Even before becoming the Tsuchikage, his power was such that he was chosen to be the bodyguard to his predecessor.[10] His skills, especially those with the Dust Release, were such that the Allied Shinobi Forces leaders agreed that the only way to stop him was to have Ōnoki confront him on the battlefield. Mū himself declares that sheer numbers alone do not matter because of the nature of his techniques, in spite of confronting nearly the entire Fourth Division at the time. A true testament of his power was the fact that he was also able to kill the Second Mizukage, another Kage — albeit at the cost of his own life.[5]
He appears to be both extremely knowledgeable and analytical, being able to discern the exact method used to locate his position almost immediately after detection, seemingly without any prior information concerning the technique in question. He also apparently deciphered the mechanisms behind his rival's Steaming Danger Tyranny and passed on the information to his student, as was later speculated by the Second Mizukage himself.[11]
Sensory Perception
Mū was a skilled sensor-type shinobi, having displayed the ability to sense chakra over a distance of several kilometres, as well as to discern the similarity between of chakra signatures belonging to close relatives such as Gaara and his father, and distinguish chakra from different populations. Furthermore, when these detection capabilities are employed in conjunction with his quick reflexes, he can avoid techniques that even other Kage find difficult to evade, even from his blind-side.

Mū has displayed a mastery in the ninjutsu field, demonstrating the capability to levitate and fly, as well as being able to split himself into two duplicates to help escape a lethal blow, but at the cost of reducing his power by half. He was also physically strong enough to lift massive rocks off of his body, even with only half of his power.[12]
While alive, Mū was seen carrying a pair of swords, implying that he was also skilled in kenjutsu.
Mū was capable of completely hiding his presence. His camouflaging ability was so great, he became renowned as the "Non-Person" (無人, Mujin; Viz "Null-Man"), a title which he gained for having neither a physical form, nor detectable chakra, while the technique was active.[13] It was impossible to detect him by normal means and so, Mū considers anyone with the ability to detect his presence worthy of praise.[14]
