Im gonna just go and say it, Aizen already used Shikai, Bankai and Hollofication !!! Although, its not exactly true either, gonna explain later down bellow
Lets take a look .. heres Aizens transformations first :
The reason why nobody noticed is obviously bcs Aizen didnt use the powers of his sword right ? However, dont you think there is something strange about Aizens sword ? Take another look .. yup, thats it - the sword is merged in with Aizen.
What does this mean ? Dont know for sure right off the bate. However, Zanpakuto is said to be a living thing with its own power. Aizens Zanpakto merged with him bcs of the Chrysalis transformation into transcendental being (transcendental means a being who has the best qualities of shinigami and hollow but isnt either off them, or so I understand its concept)
So now, if Aizen is "transcendental" then its highly possible that he lost his Zanpakuto .. no, rather, it merged with him and with HGQ but as a result it lost its original powers.
Still, as we have seen - Aizen transforms further !! Its not shinigamis Shikai, Bankai nor Espadas Ressurection .. these Aizens or Ichigos were transformations of Transcendentals. They also look veeery similiar to Ichigos transformations so far - most likely why Aizen thought that Ichigo was a worthy transcendental material.
Now Ichigos :
There are similiarities but also .. notice the difference ! Im not talking about cosmetics here or the details, its more of a yin/yang kind of difference. I take it that even a transcendental being cannot be a perfect balance of shinigami and hollow. It has to turn slightly into one or the other direction.
Ichigo slightly turns into shinigami direction. Thats why he is with the shinigamis, thats why his base of transformation is shinigami putting on a mask, etc. Aizen slightly turns into hollow direction. Thats why he is with the hollows, thats why his base of transformations is hollow nature (monster like), etc. Its just like Yin - Yang !!!
Ichigo is not a vizard, he is a full transcendental !! Just like Aizen !
- What happens if one devours the other, like if Aizen devours Ichigo or vise versa ? The circle will be complete and a true god might be born ? Maybe the Royal King is just like that ?!
