Oro could have and should have done this before

[Floydical]

I saw another thread on this matter and responded to it, but I wanted to bring all my ideas together on the matter and create my own thread on this issue. It ran a little long, so if you want the synopsis, skip to the last paragraph.

My issue is in regard to Oro implementing this plan now, when he clearly could have done it long ago, ie when he was actually alive for the first time. We know for a fact that Oro had this plan all figured out before Sasuke killed him, simply because he took the time to write the whole plan down on a scroll and store it in a secret room that not even Kabuto knew about. He did this all BEFORE Sasuke defeated him. This means he had planned the idea for some time and knew it would be successful if implemented.

Now we can't say for sure if he had this plan in part 1, but I think its safe to saw that he had it ready in early part 2 since he died relatively early in that storyline. So that means Oro had ample time to implement this plan between the start of part 2 and when he planned to take Sasuke's body. So why would he not take the risk of reviving his arms at this time and give himself a much better chance to beat Sasuke if in fact Sasuke resisted? Why would he wait to restore his arms until after taking over Sasuke when he was already in such a weakened state to begin with? To me, there is no logical answer, other than the fact that Kishi was saving this for the war or hadn't come up with the storyline yet. But as a plot-line for Oro, it makes no sense to do this now.

Some people have said that he waited this long because he didn't have the mask that he needed, but that makes no sense because of how easily he obtained it here. We know that the Uzumaki building they visited was outside of the village, so Oro could have retrieved the mask at ANY TIME without fear of being detected by the leaf. Not only that, but he could have revived the Hokage ANYWHERE, not just in the Uchiha hideout, and store them for later. We know for a fact that Edo's can be stored for an extended period in their coffins, so why not store them for a very long time, perhaps years?

Another argument is that since the Sound village was disbanded and Oro lost an ally in the Sand, that he did not have the military power to defeat the leaf EVEN WITH the revived Kage. But again, why not restore your arms AS SOON AS POSSIBLE and store them until you took over Sasuke and prepare a small army for battle? It makes no sense at all.

Here are a couple good explanations I have heard for this:

Because he didnt want kabuto to know how to summon them. This was probally his insurance policy against kabuto or anyone else that threatened him.

There is probably a trust issue at work here. Orochimaru has to sacrifice himself and someone must restrain a body for him to inhabit. Kabuto might just let Orochimaru perish rather than assist. Sasuke needed Orochimaru to summon the Hokage so there was mutual advantage.

The insurance policy against Kabuto is a good idea, but why not simply implement this plan ALONE and never tell Kabuto about it? Moreover, why can't he survive this on his own? I mean am I missing something or is simply body shedding enough to survive this?:



Why even bother with the Zetsu clone? Oro has shown ample examples of surviving wounds like this by using body shedding alone!

My major point here is that from everything we know, there is no reason that Oro could not have implemented this plan all by himself at any time as soon as he found the secret on the matter. He had hundreds of sacrifices ready to go and did not need the Uchiha shrine to revive the kage, he could have done that anywhere. In addition, he knew the Mask was hidden outside of the village, well within his reach, and had body shedding to survive a fatal would to the stomach. There is no reason for him not to implement this plan, power himself up in order to compete with Sasuke, and revive and store the Kage for later in order to salvage his plan to destroy the leaf somewhere else down the line. I honestly feel that this whole plot-line is very out of place and has only come about now because either it works better with the story or Kishi hadn't thought of it yet.

Thoughts, opinions, comments, concerns?

[Twin Steps]

tl;dr, but I'll rep you for effort

[TheCloudsBlackLightning]

He was planning on taking Sasuke's body before he took action. Not to mention he wasnt at full power along with Jiraiya constantly on his trail. The risk were too high.

[blazekev90]

So you expected him to re-enter the village, armless and all to try this, knowing the village would be fully aware of his presence.

[Ero sennin jiraiya]

I mentioned this in another thread, but he couldn't do it before because the mask was located in Konoha, and he was a wanted criminal. He was weakened and it would have made it difficult for him to do so. Not only that but he can only use his body transfer jutsu once every three years, and that was essential for getting his arms back from the reaper, as if he couldn't transfer bodies he would end up sealed in the reaper along with his arms.

He had a small window where he could have done it before he tried to capture Sasuke but like I said he was weakened and the mask was in Konoha.

But the building was outside of the village. This means it was outside the zone of detection. See here:

Again, the building was outside of Konoha, not in it. And what does being weakened have anything to do with this? All the strength he would need would he enough to get himself to the location. He could have even delayed the revival of the Kage if it would have been too much trouble.

What does the body transfer have to do with anything? He didn't need body transfer to survive that, only body shedding. Please explain to me WHY he needed to actually transfer bodies to survive that? He could have simply restored his arms there and use body transfer somewhere else down the line.

Either way the building was nearby. If I was him I wouldn't risk going anywhere near Konoha for a while until I was not in terrible shape.

It looks like the me that he didn't just shed his skin, but transfered into a zetsu. He had Suigetsu hold a zetsu down so that he could do it. Considering this is how he did it in the manga there really isn't any proof that he could of just shedded his skin, while i'll acknowledge it as a possibility.

He may have not done it back then for a different reason. Like perhaps he didn't know about the mask? Remember when Hiruzen used the tech on Orochimaru? Oro didn't even know about the technique. Hiruzen said "I'm going to use a technique that even you don't know" meaning Orochimaru didn't have any knowledge of it. He very well could have found out about it later on after doing research, and that's why he didn't do it right away.

If my body transfer theory is correct, that would explain this. If you'd rather say it's a plot hole that's your choice though. I'd rather logically think about it and come up with an explanation...

Most villages have barriers set up, I believe the leaf had one as well. Pein mentioned this before invading the village if I'm not mistaken. Also, upon using the Mask, Orochimaru would have needed a sacrifice. After waiting for Sasuke to arrive, it was too late. He probably was expecting to have a new (perfect vessel) by than. However, that didn't work, so he had to resort to using a dub. Part started with his basically in the same situation, but as soon as the time came for his to switch bodies, Sasuke attacked him. Orochimaru wasn't expecting this attack, as they came to a agreement. Even if he did have a small idea of Sasuke turning, he thought nothing of it, as he still was able to leave his defenseless in their altercation. But once again he underestimated Sharingan. I think was him simply underestimating every and overestimating himself.

Considering his life depended on it, yes he should have taken the risk. He should have realized that Sasuke would resist and should have known that getting his arms back would have been insurance to overcoming Sasuke. Considering the pain he was always in and the power that was taken from him, it would have been worth the risk especially since it was not within the detection zone of the Village. He coudn't wait any longer to body transfer when Sasuke came to kill him so I think it would have been well worth the risk for him to go to Konoha's border as soon as he came up with the plan. He could have easily done so early in part 2, when he was strong enough to make the trip and considering he had a strong need to get his arms back.

I do have an explanation for it. Either Kishi did not come up the idea until now, or he saved it for the war.

Again, its clear to me that Body Shedding would have been plenty adequate to save him, considering what it has healed him of in the past. And to clarify, I made it clear that I thought he only knew about this in part 2, I don't think he had any knowledge of this in Part 1.

YW . Too bad Toonami isn't as good now as it used to be.

Your opinion *shrugs* I'm not going to try to convince you otherwise.

We really don't know when he learned about the mask though. That's the kicker here....we don't know how long he even had the knowledge that he COULD do this. Also there isn't any proof that he absolutely needed the body transfer or not-he could have just shed his skin-but any suggestion we throw fourth is really just opinion as it hasn't been specified.

Maybe Kishi will make it clear later on. Don't cross your fingers though, knowing him, he wont go into detail. It is what it is. Honestly I'm just happy to see Orochimaru with his arms back seeming more powerful than ever, as maybe we'll finally get a proper fight for him displaying his true power. He's a character that has been trolled quite a bit in the past.

Only thing good on toonami these days is Naruto and Bleach. I hate the Naruto english dub though so i don't watch it.

Why the hell is thundercats on the lineup? *sigh*

[Floydical]

Just to remind you guys, the barrier you speak of only extends to the wall of the village:



The manga clearly states that they far outside the village, so this isn't in the village's barrier like you may think.

[Sarutobi Sensei]

Yeah, you have valid points.. The whole thing is a bit fishy, Orochimaru should have done this before..

I think that Uzumaki shrine on the outskirts is something a whole a lot more.
While Tsunade and Danzo was running things, I really don't think it is just a building outside the village that anybody could simply walk in. Death is written all over it. The ninjas are gone to war, and the remaining r rebuilding Pain's destruction. I'm not surprised that place got deserted so Orochimaru and the others walked in so easily.

One question I have that the manga has yet to answer, will the mask work instantly the second a person puts it on? or does it have to be in the Uchiha shrine to make it work?

Just a wild guess, maybe it does work instantly, but only the uchiha shrine can reverse it? If it is that way, then it would explain why it took Oro so long.

[sLm]

Why didn't anyone notice Orochimaru and the others entering the Leaf? You just proved that a barrier was around the village, they should have been detected right away!

[★Gyakusetsu]

Yes, there has definetly been a combination of suspiciously fortuitous events going back to Juugo and Suigetsu's discovery of the scroll. These events all leading up to Oro's decision with the ultimate goal of having both Sasuke's body and his arms again. There is little chance that Oro would give up Sasuke's body in exchange for his arms and if Dr. Proof's theory that by having a body fused with Hashirama's DNA shortens the wait time for the use of the body transfer technique then suddenly having a Zetsu handy is very convenient. Very nice of Tobito to have provided just enough clones. Somethings definetly up here. Great job.

[Floydical]

Why didn't anyone notice Orochimaru and the others entering the Leaf? You just proved that a barrier was around the village, they should have been detected right away!

The point I was making was that the barrier only extends to the outer wall of Konoha. Anything within that wall is considered part of the village. So the fact that Suigetsu said they are outside the village means they are outside of both the wall and the barrier. Once they went to the Uchiha shrine, yes they were in the village but the barrier squad likely is not there anymore. The fact they were not detected does not prove the Uzumaki building was in the village, we can only go off what Suigetsu said.

[Ero sennin jiraiya]

Are you talking about in the recent chapter, or in the past during the chuunin exams?

Konoha seems pretty deserted right now, so that explains that.

During the Chuunin exams a lot of ninja from other countries were entering the village. I don't think a barrier can detect exactly who enters but just that someone has, and during that time since there was high traffic nothing would seem out of the ordinary.

[Frikid]

1. HE had to train sasuke.(he can't really leave that guy alone )
2. He can't do his plan alone, he need a living being to be with him, since the technique costs you your life.
3. Akatsuki was spying on him so they always knew what he is upto.(kabuto can't be the only source, considering zetsu is such an expert spy)
4. Plot!

Hmm I guess its possible the Uchiha shrine might have some significance, but I really don't see how Oro couldn't have done this anywhere. Its just very convenient with the plot for them to be revived there, thats all.

Not leaving Sasuke alone is a good point. Sasuke might get suspicious or go on a rampage if Oro wasn't there for a day or 2, but still, if it was for his arms and his future safety and health, again it would have been worth the risk.

Again about this process costing you your life.... Oro is the perfect candidate to be able to bypass this. We have seen Oro survive grievous wounds and EVEN REGENERATE LIMBS using body shedding. To me, it was obvious he survived the death by body shedding and simply took the body of the Zetsu out of convenience afterward.

The Akatsuki point is potentially a good one, but I think it would be difficult to say that they'd be prepared enough to stop him. Yes Zetsu might have known about his movements and tracked him, but it was not common for Zetsu to provide intel fast enough to save an akatsuki in trouble or prevent and event from happening. I don't think he would have been able to realize soon enough what Oro was up to before he finished what he was doing.

[thegame]

Uhm, I didn't read your entire thread, but the overall premise that Oro should have done this before, is wrong.

The explanation is quite simple. He couldn't

To do this, you needed to give up your body. In other words, you would die by doing it. So you would need to have your "body-take-over-technique" ready. This technique clearly was only usable every 4 year or something like that.

Oro was ready to take over Sasuke, but failed, so he could use this technique now without problems, since it failed the last time. So he simple took over Zetsu's body.

Also thus it can be concluded that Oro didn't know about this method, when he took that other body (the one before Sasuke).

I mean, the answer really is as simple as that.

[meowNverse]

Dont you need an Uchiha to get into the shrine?
There was some seal kind of square rock in front of the entrance.
If not,
than the risks could have been to high to get near a fully populated Konoha without your arms, nor a body to get into after it gets slashed(he used his body transfer on the zetsu right?).
His body transfer could still have been on cooldown.

Even if a body is not needed, than its still dangerous to get there without his arms I think.
You say he survived wounds worse than this, but he said that he needed to be sacraficed, in order for the belly to be cut open, so this wound might have been lot worse than it looked.

Konoha is almost fully abanboned atm.
Getting near it and/or in it, is easier right now.

Do you feel this are good reasons, or not?

Tbh if these reasons fail, than I dont know either why he didnt go sooner
Maybe not wanting people like Sasuke, Kabuto or others to know his plan.
Maybe overconfidence, thinking he could take over Sasuke without arms.

I have something else.
If he took over Sasuke his body, wouldnt it have been quite a waste?
If he went to the shrine as an OroUchiha and get back his arms, than he would have to sacrafice that body right? Or maybe he had some backup plan to maintain the body/sharingan powers and still get his arms.

[Sarutobi Sensei]

Hmm I guess its possible the Uchiha shrine might have some significance, but I really don't see how Oro couldn't have done this anywhere. Its just very convenient with the plot for them to be revived there, thats all.

Yeah, I wondered why Orochimaru didn't put the mask on right away when he retrieved it from the Uzumaki shrine. I really do think the Uchiha Shrine serves some sort of purpose, we just dont know it yet.

@bolded part,

Oro says " "But i'll need to be sacrificed for that" .
Ïf oro don't have anybody with him, his soul would be taken by the Reaper. That is why i said that.
To make it more clear, after undoing RDS and performing edo tensei, oro quickly switched his soul with a zetsu soul and that is why the reaper took zetsu's soul with him and oro is still alive.

So why would he not take the risk of reviving his arms at this time and give himself a much better chance to beat Sasuke if in fact Sasuke resisted?

To me, there is no logical answer, other than the fact that Kishi was saving this for the war or hadn't come up with the storyline yet. But as a plot-line for Oro, it makes no sense to do this now.

You make a lot of assumptions about how long Orochimaru had this plan available, and how able he would have been at any point to complete it. Remember, this isn't just some thing that he could do any weekend. It involved breaking into a shrine at Konoha to steal a sacred mask of some variety, then performing a ritual that required him to bring along 5 LIVING SACRIFICES, all of whom would likely be trying to fight back. All the while Orochimaru didn't have his own arms, didn't have hardly any sound ninja left, and most of the rest of people on his "team" were laboratory test subjects who were trapped in dungeons and wouldn't have helped him even if he asked.

Let's look at his timeline:
1) Orochimaru loses his arms, his Sound ninja army and his biggest ally (the sand village) after the battle of Konoha.
2) The sound 4 and Kimimaro all died shortly after the failed invasion. This means that Orochimaru's only "real teammate" was Kabuto
3) Orochimaru's first option was to contact Tsunade to try and fix his arms that way. She and Jiraya defeated him and wounded Kabuto, who didn't have super-healing yet.
4) After the battle, Orochimaru finally acquires Sasuke, although Sasuke is not a loyal helper like Kabuto
5) Only AFTER the battle with Tsunade/Jiraya would Orochimaru have started looking for a plan B, and by that time he was busy training Sasuke (and fighting/spying on Akatsuki, and rebuilding after the failed invasion, etc).

Orochimaru didn't even start looking for the plan B until AFTER the end of Part 1, and at that point he didn't have any capability to do it. Konoha would have been too secure until AFTER the invasion of Pain. By that point, Orochimaru was already "dead".

Orochimaru didn't need to research this plan until AFTER Tsunade turned him down. At that point, we don't know HOW LONG IT TOOK Orochimaru to develop the plan. Did he do it that afternoon after coming back to his hideout? Did it take him a week? A month? Three Years? We don't know.

We already covered most of that. I don't see any indication as to why the Uchiha shrine is needed. He could have summoned the Reaper anywhere, and gotten his arms back. He only needed to get into the Uzumaki building for the mask and thats all. Considering the building was on the outskirts of the village, it was not within the barrier and could have been accessed by him even with a fully populated village. Again, I don't think the body transfer was actually required. He needed to be 'sacrificed' yes, but that's only in terms of his physical body. He would have died if he stayed in his body with that cut. But all he had to do was body shed and survive it, he didn't need to body transfer.

Clearly he was overconfident, yes. But your point is more evidence in my defense. Since he knew about being sacrificed and obviously planned to do this after taking over Sasuke, than yes he must have been able to do it without body transferring again, it only makes sense. Imagine if he did have to sacrifice Sasuke's body to get his arms back, that would be crazy so this helps defend my point.

Again, if it was a matter of people not figuring out his plan, he could have postponed half of the plan. He could always get his arms back asap then revive the Kage later. There was not a need for him to do that right away.

Uhm, I didn't read your entire thread, but the overall premise that Oro should have done this before, is wrong.

I mean, the answer really is as simple as that.

No, I don't feel that explanation is good enough. Obviously he didn't know about it in part one, but that's not my focus here. As I've said multiple times now, he only needed to body shed to survive that. We have seen him body shed into a new form of his body before:



He simply took the Zetsu because he was going to have to body transfer at some point anyway. Body shedding would have been enough to save himself there since we have seen it save him from wounds like that before, so its not like he needed to transfer just to survive.

@bolded part,

Ïf oro don't have anybody with him, his soul would be taken by the Reaper. That is why i said that.

I don't think you read the chapter right. Oro did not switch his soul, he switched his body. His soul was not taken in the process, only his body since he had to inflict a grievous wound on himself. Everyone is saying that he had to switch bodies to survive, but he didn't. If the 'sacrifice' really included his soul, the reaper would have taken it no matter what, even if he switched bodies. I believe the Zetsu 'soul' you are talking about being switched is not his soul at all, its the soul of one of the kages being forced into it:

You make a lot of assumptions about how long Orochimaru had this plan available, and how able he would have been at any point to complete it. Remember, this isn't just some thing that he could do any weekend. It involved breaking into a shrine at Konoha to steal a sacred mask of some variety, then performing a ritual that required him to bring along 5 LIVING SACRIFICES, all of whom would likely be trying to fight back. All the while Orochimaru didn't have his own arms, didn't have hardly any sound ninja left, and most of the rest of people on his "team" were laboratory test subjects who were trapped in dungeons and wouldn't have helped him even if he asked.

Let's look at his timeline:
1) Orochimaru loses his arms, his Sound ninja army and his biggest ally (the sand village) after the battle of Konoha.
2) The sound 4 and Kimimaro all died shortly after the failed invasion. This means that Orochimaru's only "real teammate" was Kabuto
3) Orochimaru's first option was to contact Tsunade to try and fix his arms that way. She and Jiraya defeated him and wounded Kabuto, who didn't have super-healing yet.
4) After the battle, Orochimaru finally acquires Sasuke, although Sasuke is not a loyal helper like Kabuto
5) Only AFTER the battle with Tsunade/Jiraya would Orochimaru have started looking for a plan B, and by that time he was busy training Sasuke (and fighting/spying on Akatsuki, and rebuilding after the failed invasion, etc).

Orochimaru didn't even start looking for the plan B until AFTER the end of Part 1, and at that point he didn't have any capability to do it. Konoha would have been too secure until AFTER the invasion of Pain. By that point, Orochimaru was already "dead".

Orochimaru didn't need to research this plan until AFTER Tsunade turned him down. At that point, we don't know HOW LONG IT TOOK Orochimaru to develop the plan. Did he do it that afternoon after coming back to his hideout? Did it take him a week? A month? Three Years? We don't know.

You make good points but most of what you are saying I already had an alternate explanation for. Oro could have done the absolute minimal, meaning take his arms back from the Shinigami and go. After releasing the souls, they would have returned to the impure world and thus Oro could have accessed them again at any time. He could have simply gone to the outskirts, taken the mask, perform the ritual there, get his arms back and head home. After he got back, he could have revived the Kage at his own leisure because no one else at that point would have known they were released.

Obviously he had the plan all figured out in part 2 since that is when he died. It should have been top priority for him to implement phase one of the plan asap, instead of waiting.
