You are a member of the mysterious Zero Squad. You not only have immeasurable Spiritual Power but also have mastered all of the four core techniques of Shinigami as well as the other auxiliary techniques. Your attainment is enough to defeat any Captain of the Gotei 13, without even using your Shikai. Moreover, there is an ability you possess that you have taken to extreme level. Maybe you have named everything like the Monk Who Calls the Real Name allowing you to manipulate Names, or maybe you are someone like the God of the Sword, unrivalled in Zanjutsu and creator of Zanpakutōs. This ability synergizes well with your Shikai and Bankai allowing you to expand the very limits of your ability, an example being Ichibe's Shikai which took the form of a large brush, granting him the ability to manipulate ink. With this power, he could suppress and erase others by enveloping them, along with their names, in black ink. As for his Bankai, it amplified this ability to an even greater extent. In his Bankai state, Ichibe could directly alter or bestow new names upon beings, causing the properties associated with those names to become reality. An additional benefit of your new position being the Ōken, which are the modified bones in your body, that allows you to create clothing with incredible defensive property and grants agelessness.
