One guy was lucky enough not to dissolve in the River of Souls and, moreover, to come out of it with a profit — having snatched from another soul a piece of special energy: chakra. All that remained was to learn to form the correct hand seals, and one could spit fire, create water, move earth, spark with lightning, and breathe wind. And also wait and hope for the awakening of the Sharingan, or Byakugan, or at worst the Rinnegan.
The lucky (actually, not so lucky) guy, after death, crawled out of Talia Al Ghul, dodged the midwife's grasping hands with a double roll, bit through the umbilical cord with his already-grown teeth, and proudly declared — I am Damian Wayne! Son of Batman!
