QUOTE--- "I have read somewhere on Google saying that Ichigo Final Getsuga is some type of Power Sealing Technique.
It would make sense that the Bankai Resemble the Power Sealing Image as the Hilt of the Sword is a Symbol of Power and the Chain from it stand for Sealing ?
Why wouldn't Zangetsu teach Ichigo this ? Remember he said "What you wanted to protect is not what I wanted to protect ?"
My guess :
The Final Getsuga will consume all Spiritual Power from Ichigo and even Zangetsu Himself to seal off someone's Spiritual Power and Ability. Therefore, Ichigo would lose all power and at the same time sealing off Aizen's power ?
Because Ichigo will lose power, so his Inner world will collapse ? and as a Zanpakutou Zangetsu just doesn't want Ichigo to lose his power....It is as simple as that.
That is one of the reason why Ishin lost his power too ? Who know what he used to seal off. Probably, Aizen's Dad KAKAKAKAKA.
Aizen's dad was somewhat in soul society, and got flamed on something, and being punished. His power was washed away with Isshin Final Getsuga. Aizen couldn't stand this JUDGEMENT. Therefore, he hold GRUDGE against the whole Soul Society. He wanted to tear it apart to rebuild what he would call "Justice." ?
My 1 cent Theory to kill time. Enjoy"---END QUOTE
Nice quote and apparently the only one on these forums with a part of their brain devoted to logical thinking....Follow me...Aizen states that Ichigo has thrown away his Reiatsu in order to gain tremendous strength...similar to his father that uses Kendo, and bridges a relationship with Engestu and Zangetsu...Isshin said that Zangetsu was going to be on a rampage, twice, and that he would soon learn why. Hollow Ichigo( which to those who have forgotten represents(ed) Ichigo's instinct) was ORIGINALLY Ichigo's power, and a natural part of him...There is no more hollow Ichigo at this point...Ichigo obviously destroyed that side of him to gain the "Final Getsuga Tenshou" NOW, with all that in mind, and going back to what I said earlier about Ichigo having NO MOAR REIATSU, it's clear to assume the reason Zangetsu was so adamant about Ichigo not learning is because it will take Zangetsu's power to form it...in other words, without Ichigo being able to use any of his own reiatsu, Zangetsu's power will have to be sacrificed in order to do so......boom.
:EDIT: This is my first post, made an account just to get people's creative juices flowing back to heir minds and not their, well...you know...
And, basically seeing as how Ichigo took the power from Hollow Ichigo back, would explain the transformation of his Bankai, or rather, what his Bankai should have looked like all along. Questions start nooow.......POST!
