[Theory] Kurosaki Ichigo and the Saigo no Getsuga Tensho

[Goetia]

This theory will be about why I believe it is possible for Ichigo to reattain the form used to aid in the defeat of Aizen, the Saigo no Getsuga Tensho.


1. The Saigo no Getsuga Tensho is a Shinigami Power

Now, here is the first reason why Ichigo should be able to relearn the SGT; it is a Shinigami exclusive power. The reason why? When Ichigo was on his way to the Soul Society with his father Isshin to stop Aizen, they stopped in the Dangai so Ichigo could get stronger. Here is the main part of this section of the theory. When Ichigo goes into Jinzen to learn SGT from Zangetsu, Isshin says something quite interesting.

After seeing what Isshin has said, it is safe to say that the SGT is a Shinigami power, and even more specifically, a power specific only to Zanpakutō with "Getsu" in their name.

2. Learning SGT Compared to Learning Shikai and Bankai

Now for the second part. If I'm going to be comparing the learning process of SGT to that of the learning process of the Shikai and Bankai, I should make it clear what the learning processes of the Shikai and Bankai are.

Shikai is the second form available to a Zanpakutō. To activate it, the Shinigami needs to learn the name of their Zanpakutō. This is not as easy as simply picking a name, for the living spirit of the Zanpakutō already has its own name. The Shinigami must be able to communicate and harmonize with their Zanpakutō effectively, which requires being able to speak to the spirit within its world.

To achieve Bankai, one must be able to materialize and subjugate their Zanpakutō spirit. Materialization means the opposite of getting dragged into the Zanpakutō's inner world: the wielder needs to summon the Zanpakutō's spirit into the physical world. It usually takes 10 years or more to achieve, plus the experience needed to master it.

The Saigo no Getsuga Tenshō is a form that Ichigo learnt within the Dangai to defeat Aizen. To learn it, Ichigo had to use Jinzen to get inside his Zanpakutō's inner world and defeat it.

Using the fact that the SGT is a Shinigami power, and that learning this ability is a combination of learning both the Shikai and the Bankai, we can say that Ichigo is able to learn this power once again, and possibly indefinitely if he is constantly getting his powers back. Though him getting his powers back after relearning SGT is unlikely.

With that, it should be safe to say that it is possible that Ichigo could relearn the Saigo no Getsuga Tensho.

Hope you enjoyed reading, and feel free to point out anything I may have missed or anything else that you feel is essential to the discussion and theory.

You have the point in your first point, but there are two problems:

1. We saw other than Shinigamis using Getsuga Tensho

2. Ichigo didn't really fused with his zanpakuto spirit. I belive he fused with Yhwach. His Shinigami spirit is White, and if he fused with his shinigami powers (White), in his Mugetsu from he would be more "whiteer", but he was actully Black (at least his hair), which lead me to assumption that he didn't really fused with his shinigami powers.

What other Shinigami used GT? Other than Isshin, I have not seen a single other Shinigami use GT. You have scans of others using it?

It would be a fair assumption to make, that Ichigo fused with Yhwach/the Quincy Manifestation, and that is what I initially believed. However, why would Ichigo fuse with Yhwach's powers if Zangetsu, White, was the dominant power of his Zanpakuto? That doesn't make sense.

 

[Forbidden Tale]

Maybe I didn't say that well. What I wanted to say is that other races can also use Getsuga Tensho:

1. Kugo Ginjo
2. Fullbring Ichigo
3. Ichigo, used double Getsuga during fight against Candice, one of his blades should represent his Quincy power, which say that Quincy also can use Getsuga Tensho.

Or rather, it's not that ones with "getsu" can use Getsuga Tensho.. Maybe, G. Tensho can be used/ is secret technique of Shiba clan.

Ichigo in all forms his forms are capable of using Getsuga. (Ichigo is from Shiba clan)
Isshin can use Getsuga. (Also from Shiba clan).
Ginjo is not from Shiba clan, but he has Ichigo's reiatsu, which let him use that technique.

I'm not really sure what you talking when you say that Zangetsu was dominant, I would actually say that whole time Yhwach was dominant. To me it seems that he was one in control when both of them were fused together in Ichigo's inner world, when he learned Final Getsuga Tensho.

 

[Charybys]

Yeah I also don't think he fused with Yhwach. Every thing else you've said seems true tho. Lets see if he'll ever release SGT again. That and his new bankai are what I'm looking for to seeing.

1. Kugo was only able to use GT because he stole Ichigo's FullBring.
2. True.
3. True.

Maybe.

When I say Zangetsu is dominant, I mean that he is the dominant power in the Zanpakuto. If I remember correctly, when one power within Zangetsu becomes the dominant power, e.g. White>Yhwach, the dominant power would've been the one to manifest, and not the inferior one. We can apply that concept to Ichigo's Bankai training. Yhwach appeared during Bankai training instead of White because he was the dominant power.

He fused with both, when he went there, tensa zangetsu (yhwach) said your opponent will be the both of us and he fused with hollow ichigo(shinigami powers)

OT: yeah he probably can again but I don't know if he will because he might lose his powers again. This technique is probably the ultimate zanpakuto technique not limited to just "getsu" named swords. It might be a technique that isshin disvocered though and that perhaps no other shinigami knew about except aizen as he learned from ichigo. If even aizen didn't know until he saw though, I guess it must be a very secret technique perhaps passed down through the shiba clan.

Now I believe aizen also fused with his zanpakuto (even though it may have dissappeared due to being sealed) and this is why he can manipulate Yhwach sense of time. But aizen didn't lose his powers, maybe because the hogyoku or maybe because he only fused with his shikai or maybe because he didn't use his "final" technique like ichigo fired his getsuga. This may provide a basis for ichigo to be able to use it and keep his powers as well.

In that case I would say that Yhwach was dominant when Ichigo used FGT. Just from the reason I mention above. Ichigo looks more like Yhwach, than White/Zangetsu.

That is why I said it was unlikely that Ichigo would yet again regain his Shinigami powers if he were to reattain the SGT.

It could very well be a technique unique to those of the Shiba clan or heritage.

Aizen completely fused with his Zanpakuto, that is how he was able to trick Yhwach. He can now use Kanzen Saimin without the need of a Zanpakuto.

That is true, Ichigo did exhibit a huge resemblance to Yhwach when using SGT.
