User blog comment:Caesarea37/Aizen and the current state of his Zanpakutō/@comment-4207271-20130322031802

All Zanpakuto have their abilities based on their wielder to some extent, So Aizen might have some perception distorting latent ability. Hitsuguya reduced the temperature around him before aquiring Hyorinmaru, Ichigo could use Getsuga Tensho with his Fullbring, Yamamoto could create flames with his spiritual pressure, so it is likely that Kyoka Suigetsu's power is merely a more powerful or more precise version of his latent power.
