It depends on the specific fanfiction. Fanfictions are known for their creativity and bending of established rules. While Naruto is a shinobi from the Hidden Leaf Village in his own series and Shunsui Kyoraku is a captain in Bleach, in the world of fan - made stories, the author may have crafted a complex and unique narrative where Naruto is indeed the son of Shunsui Kyoraku. Maybe there's some sort of magical or time - traveling element involved to make this seemingly odd connection work.
Naruto's bankai might incorporate his fox - like features. Given his connection to the Nine - Tails, his bankai could have a large, fiery fox form that enhances his speed and strength, much like how his Nine - Tails Chakra Mode works. His zanpakuto could also be related to the rasengan, perhaps having the ability to fire off rasengan - like attacks from the blade or using the spinning energy as a defensive mechanism.
One possible plot change could be Naruto having different abilities. Since Shunsui Kyoraku has unique powers in Bleach, Naruto might inherit some of those. For example, he could have a zanpakuto - like ability in addition to his ninja skills. Another change could be in his relationships. His connection to the Bleach universe through Shunsui might introduce new characters into his life, like other Soul Reapers. Also, his backstory would be completely different, perhaps involving the Soul Society instead of just the Hidden Leaf Village.
Yes, there are likely some fanfics out there where Naruto has Bankai. Fanfic writers often like to combine different elements from various anime. They might create a scenario where Naruto somehow acquires Bankai abilities from the Bleach universe. However, the quality and exact nature of such fanfics can vary greatly.
In the context of the relevant novel, Aizen's Bankai is a very powerful and important aspect. It represents a high level of his power and is often a crucial factor in the plot development, especially in battles and power - struggle scenarios within the story.
Yes, in some fanfictions, Naruto is given a Bankai. Fanfiction writers often like to cross - over different anime concepts. They might give Naruto the power of a Bankai from 'Bleach' to create unique and interesting storylines. This can lead to some really cool battles and character developments that you wouldn't see in the original Naruto series.
In fanfics, anything is possible. Since it's a fictional creation, an author could write a scenario where Naruto has the ability to use Bankai. However, in the original Naruto and Bleach universes, their powers are completely separate, with Naruto having chakra - based ninja abilities and Bankai being a high - level power in the Bleach world.
In the manga, Senjumaru did not employ Bankai. The character's abilities and actions were depicted differently without resorting to this particular power.
