If we believe the theory that Shikai are what a Shinigami is and the Bankai is who they want to be. It makes sense why Kisuke's Bankai is what it is, the ability to manipulate and change things as he desires. Kisuke's inventions are all about this and it honestly makes sense that his Bankai would be hacks in this story of way. Sort of like how he invented a tool to reach Bankai in three days. It's all about gaining the system to him.

My only real complaint about that fight was the lack of the perfect opportunity to see Yoruichi's Zanpakuto. Instead they just expand her Shunko abilities and give them a weird side effect. When in reality, if her Zanpakuto did that I'd understand more why she doesn't use it much, and instead relies on her Hakuda and Shunpo.

Also, I'm assuming the reason Askin's ability didn't work against Grimmjow is because Urahara used his Bankai to alter Grimmjow's reiatsu. Because remember, you can bypass Askin's ability if you alter your reiatsu. The only reason that didn't work for Yoruichi's new form is because she couldn't really damage him enough before he became immune and healed. Grimmjow literally killed him before he could gain an immunity. Which is how you bypass immunities in real life to, you hit it faster than it can react.
