'Old Man Zangetsu' always used Ichigo's Hollow powers when learning the intricacies of his Zanpakuto.

Not that any of this matters, because Final Getsuga Tenshou was a contrived plot device in order to counteract another contrived plot device (Aizen's evolution via Hogyoku).

Though i know where you're coming from, i've taken into consideration other points against the theory; points i've seen within other forum discussions. There are many good points against it, including what you've mentioned. And i'm not one of those pushy theory guys who insist that they are right, i'm just trying to do my best at connecting the dots and having my theory hold water. I learn as i go, through the help of the opinions of others.

And to address your good point of FGT being a Zanpakuto technique:

I can see it being that, but Tensa Zangetsu wasn't Ichigo's true Zanpakuto. Tensa merged with the Hollow, who was in reality the true Zanapkuto, so i can see it being that it was still a Zanpakuto technique being trained. But i'm looking at the fact that Tensa was the dominant personality in the merging; and he was the Quincy manifestation. Ichigo being under the false impression that Old Man and Tensa were his Shinigami powers and Zanpakuto spirits, from his perspective it was indeed a Zanpakuto training. So what was supposedly (according to my theory) a Zanpakuto technique, was thus intercepted by the control of his Quincy spirit.

So there's that point of view. Another viewpoint would be that, yes, it is indeed strictly a Zanpakuto technique, on its own. The point of my theory, was that Isshin applied the idea of a Quincy technique (guided by the basic principle) to his Zanpakuto. Trying to create something new. Think of it this way: Aizen used Hollowfication experiments in the goal to give new powers in addition to Shinigami powers. In my theory, such was the same with Isshin, yet he looked instead to a Quincy method (inspiration of it, anyway) as a form of help. Seeing as how Isshin has a connection to Quincy characters (Masaki and Ryuken), he'd know a thing or two about their powers.

So you could say that Isshin is the one who created this Zanpakuto technique. That is, if he has truly learned it and was able to apply it to his Zanpakuto. If he wasn't successful in learning it himself, then he's still to thank for passing the idea to Ichigo (who was more capable anyway, considering his Quincy side).

I just imagine, if a Shinigami such as Isshin were to know of such a technique which apparently is unheard of among the whole rest of the Shinigami, where would he suddenly come up with the idea to get his Zanpakuto spirit to teach him, and Isshin then figure out how it works and accept the blade? With the resulting aftereffect being a loss of power? Just makes my theory wheels spin frenetically, hahahah.

Either way, the story presents it as Isshin being the sole person to have knowledge of such a technique, and then passing that knowledge to Ichigo. My theory is to guess how Isshin obtained that knowledge in the first place. :)

Also, for it to be *derived* from a Quincy technique and thus created as a new Zanpakuto technique, it would definitely be seen as strictly a Zanapkuto technique when observed on it's own.
