after watching nagato and itachi vs naruto and killer bee i think nagato has some type of limbo his summoning what not able to bee seen by killer bee or naruto what do u guys think
No, because after Madara used Limbo for the first time, no one knew what it was, not even Kurama. If Nagato had used it, Naruto or Kurama would've sensed some type of similarity.
XD nagato using limbo. That never happened but if he did he wouldn't have use it to its limits. But think of it like this . Nagato used six dead people to do the fighting so I would think that's his limbo but people can see them. And madara upgraded it to invisible shadows of himself what do you think
