Impure World Reincarnation Allied Forces

Reanimated Allied Shinobi Forces (穢土転生連合軍, Edo Tensei Rengōgun) is a group of reanimation shinobi from various countries, whose mission is to print out strong shinobi, previously neutralized by the Allied Shinobi Forces.

Background
When Orochimaru tried to perfect the Summoning: Impure World Reincarnation, he looked for DNA from strong shinobi who had already died in order to resurrect them. He introduced Kabuto Yakushi to this, and he continued to collect material, replenishing the collection not only with good samples, but also with weak shinobi, who more often than usual came across during the experiment. Kabuto decides to keep them all for later use.
