I know it hasnt been shown, but...Yoruichi has stated that the only Captain that couldnt Bankai was Kenpachi. (thats changed now) There are three ways to get to Captain status. 1- Be voted in by 3 Captain level with showing of Bankai 2- Kill the previous Captain with witnesses 3- 6 recommendations and aprroval from 3 of the remaining seven

How did Aizen become a Captain? 3- He was placed under Shinji so Shinji could watch him. Im doubting he got recommendations 2- The previous Captain went missing. After Aizen Renji wanted Ikaku to take a Captain spot cuz he knew one had to Bankai. So it isnt just the Lieutenant takes over 1- if 3 Captains saw his Bankai....oh snap
