What if Aizen's zompakuto Kyoka Suigetsu was what made him evil? And it controlled him, because don't forget the second it's unsealed, boom complete hypnosis. Anyways. Let's see what would happen if this where to happen.

Aizen Sosuke the go bantai taicho was taining one day and he sighed. "my my what a dreary day it is in seireitei."He muttered. At the time he was only the Go bantai Fuku-taicho. He was training to achieve Bankai to take his taicho's place. "If I see another sheet of paperwork when I get back."He said sighing. Aizen said , "Scatter Kyoka Suigetsu.."And that's when it happened. His zompakuto's illusionary qualities kicked in. A tall dark figure unlike a hollow's stood before Aizen. It's twisted shape changed every now and then. "listen and listen well young one..."The figure said in a warm yet deceiving voice. Aizen listened to what his Zompakuto's spirit told him. "Ah I see so to create the ultimate hollow I need to obtain the Hougyoku."the young aizen said softly as his zompakuto's spirit disapepred. His eyes glazed over slightly a dull sheen to his eyes. He blinked.. In a matter of weeks with the new power he had gained from his zompakuto he became the go bantai taicho. ⌠Ne, Gin? You know the plan. Now let's look at the little kids at the academy to see who should join our ranks."Aizen said. "Hai taicho."Ichimaru said with his fox-like grin. Aizen nodded and started to walk towards the shinigami academy his captain's haori swaying slightly behind him. He started to use Shunpo to reach his destination faster.

Aizen walked forward now, His eyes scanning the crowded road. 'pathetic.' he thought. "Gin..."He said and nodded. Ichimaru nodded back. They both hid their inner ambitions.

"A group of Menos grande have been reported! The kids at the academy are there and they can't get back in."A messenger said.. Aizen nodded. "Ichimaru let's go."He said and used shunpo to appere there. "My my, a nasty group here don't cha' think."Ichimaru said and then pulled out his zompakuto. "Impale Shinso."He said and his zompakuto extended making quick and easy work of the hollows. A quick glance and it was over. Years later and the betrayal has only just been found out, The arrancar war has started now will anyone find out, that indeed Hinamori is the closest one to being correct about her taicho?
