I know Madara broke out of Edo a couple of weeks ago but I haven't had the time to post this yet, but it has been bugging me...a lot. Like come on Kishi, really? Madara just so happens to know these secret hand signs that lets him break free from Edo? Give me a break. I have defended everything Kishi did so far, but it is just getting ridiculous, even more so now that Oro is back.
Seriously, Madara just happened to know the secret seals to break out of Edo? How would he possibly know these seals. Ok maybe he found them out, somehow, but the thing that bothers me the most is...how come ****ing TOBIRAMA, the CREATOR of Edo Tensei, didn't use these secret seals right away when Orochimaru summoned him, to break out of the Edo?
Because Tobirama was under mind control. Remember when Orochimaru inserted the seal into his head, and he became a fighting machine under Orochmaru's control? Madara could only use those seals to break free from the technique AFTER Kabuto released Edo tensei. Notice how Dan, after Kabuto released him, was able to use a technique he wasn't able to use before and go to save Tsunade. After Kabuto released the technique, but before the soul left for the pure realm, there was a moment when the bodies were able to control themselves. Madara used that moment to release himself. Tobirama never had that moment,
he was always under control of Orochimaru.
There was a small period of time from the time he was revived until when Orochimaru put the talisman's into his head to fully control him. Your telling me the Second AND First Hokage, the two strongest Hokage, couldn't do this?
And you're telling me that they had complete control over their bodies before the talisman seals were put in their heads. It didn't look to me like they were conscious or able to move at that time. Do you have any evidence to suggest that they were not under some level of control at that point AND that they were free to move? I see no evidence of that.
As for Orochimaru...he obviously put a part of his soul into the curse marks, and Sasuke was able to use that to revive him, but there is a major flaw in this, or at least I think so. If he only put a part of his soul into the person, that means when he gets revived he will still only have that part of his soul in the new body, but that would also mean he wouldn't be able to use whatever body parts that that soul was not bound to.
Wait a minute, what exactly do you mean by "soul"? Orochimaru only said that part of his chakra and consciousness were in the cursed seal. He didn't say "soul". But let's ignore that. Let's just call it a translation error or something and he did say "soul". Nowhere in the manga is it implied that a soul is broken up the way a body is broken up. Nowhere is it said that Orochimaru put a specific part of his soul-body into these seals either. This doesn't mean that Anko's seal got Orochimaru's Soul's leg, and Sasuke's seal got Orochimaru's Seal's arm. You're talking about dividing up something ethereal the same way that you divide up a physical body. That's a pretty big logical leap, and isn't supported by the manga. You're also making a very large and unsupported logical leap by claiming that the way the "soul" is handled during the death god seal is the same way the "soul" is treated in Orochimaru's cursed seal. The way Orochimaru explains it, he put his senjutsu chakra into the seal and a portion of his consciousness stuck with it.
Notice also that Minato and Kushina only sealed part of their chakra/soul into Naruto, but when they appeared in his mind it wasn't just a foot or an arm. We saw the whole body. This is even though Minato's "soul" is apparently sealed in the stomach of the death god. This doesn't work using the simple physical interpretation you're following.
Tl;dr: The soul doesn't work the same way the body does.
And people saying that the little snake that "escaped" Itachi's Totsuka Sword was actually Orochimaru with his ENTIRE soul, I don't see how that's possible. Like really, he REALLY turned himself into a little tiny snake with his entire soul and escaped the sword? No, he didn't. The sword started sealing him basically instantly, if not instantly it definitely started sealing him before Oro even knew that it was the Totsuka Sword, so he wouldn't be able to do anything to "escape".
You're making the same mistake here. You're saying that the last little white snake didn't hold Orochimaru's soul. Sure, it didn't contain the entire thing, but then again, neither did Sasuke's cursed seal. Or anko's cursed seal. Wait, how many cursed seals were there again, each of which had a portion of Orochimaru's "soul"? And didn't Kabuto have some of Orochimaru's "chakra" in him also?
The soul in the world of Naruto isn't like a candy bar, where you eat half of it and that half is just gone. It's more like water. If you pour one gallon of water on the floor, the floor is wet. If you pour half a gallon of water on the floor, the floor is still wet. If you put a single little drop on the floor, the floor in that little space is STILL wet. And, no matter how many times you divide it in half (assuming you don't have a nuclear furnace in your basement), it's still water.
Further, in the manga there's never really a distinction between a soul and chakra. When Minato and Kushina put their "chakra" into Naruto, their consciousness and their "soul" appeared to go with it, EVEN THOUGH Minato's "soul" was clearly sealed into the death god too. Also, we know that Minato sealed half of the fox's "chakra" into the death god (even though the death god appears to deal in "souls"), but the part of the fox inside Naruto is still clearly 100% complete, has all his limbs, and is STILL more powerful than 5 other bijuu combined. Wait, what did Minato seal, again?
Chakra is something that WE KNOW regenerates. If you use all your chakra, and then get some rest, your chakra comes back. If Orochimaru gives away 90% of his chakra, and then waits for a while, he'll be back at 100% and the other person will still have that 90%. We've seen examples of chakra regeneration HUNDREDS OF TIMES in the manga.
If your soul and your chakra are essentially the same thing, and if chakra regenerates (a process which appears to be tied to the heart), then so long as Orochimaru has a body his chakra will regenerate so long as he isn't at 0% (because at 0, you die).
