Summoning Rinnegan

Through the power of the Animal Path, the user is able to summon animals which possess copies of the Rinnegan. As with the Six Paths of Pain and the King of Hell, animals summoned through this technique are visually linked to the user's own Rinnegan, offering them a greater field of view. The summons' bodies are also adorned with a number of black piercings, allowing the user to control them remotely through the use of their chakra.

Trivia

 * When Nagato uses this technique, he refers to it simply as "Summoning Technique", whereas Kabuto Yakushi uses the technique's full title.
 * Unlike the usual Summoning Technique, this technique does not appear to require a blood offering.
