We are making our own assumptions based on what we have seen up to the seventh gate. It then has the added hype that it surpasses the power of all previous gates and grants power greater than the kages. All-in-all, it's likely one of the most haxxed jutsus in NVRelease of all the 8 gates was never shown. I don't know how any of you can compare something, which is till this day non-existent in manga, to any shinobi's powers.
It does not need them, we've all read what 7th gate Guy can do, and we all know the 8th gate grants power greater than the Kages. You seriously had to -rep this user because the thread did not have what you were looking for? *****.Provided no facts, statistics or scenarios to explain theory so -rep.
I think 8th gate edo Gai> edo Madara. the speed and power would be insane.First question would be whether or not people brought back by edo tensei can feel physical pain. Plus we have no idea what the 8th gate allows the user to do, all we really know is that the user dies afterward. one question I had was if edo nagato were still alive, could he continually use the jutsu that brings people back to life? Cause that would be an intense power. if he could, then what would stop edo madara from bringing his 'allies' back to life? I think edo guy would own most people, but there are a few that could take him on, specifically edo madara.
