He trolled everyone and was behind everthing that took place in Naruto just like how Aizen was behind everything and even all of Ichigo's actions. It's like BZ and Aizen are watching and reading their own manga.
This is but one example of how badly Aizen can screw people over if you aren't careful. This is also one of my favourite fights in Bleach.skip to 6:00

He would've killed Ichigo had his arrogance not gotten the better of him against Urahara.Aizen planned so damn far ahead and just knew everything.
It was ridiculous.
Sadly enough he lost to his arrogance.
Should have just ended Ichigo.
