so aizen performed hollowfication?

[captain_jake_23]

in TBTP does he perform the hollowfication?
sorry i closed my other post just before i thought of this question

[Nocturne' Ichigo]

any one of those links i posted in the other thread could probably answer this question...According to the flashback...Aizen was testing this hollowification process...

I'd be careful with opening threads about topics that can be found when searched....
