Plans and Progress
Abyss Feeder Project
He actually doesn't know what the creatures are called, but the players do so we'll just call it that.
As of now, Aizen has removed one of Luciela's arms and has been using her flesh to experiment on natives. He keeps the varied results in cages in his basement, because he is That Guy.
Status: Ongoing. Will perhaps reach its culmination in April.
Arrancar Project
Aizen has had Gin collect various Hollows for him. Once again, he has been experimenting on them to see if it's possible to create usable arrancar within the confines of Anatole. He keeps the results of these in cages in his basement as well.
Status: Ongoing. So far, the results have been mixed.
Investigations into the Mist
Aizen has Yazoo investigating this, having sent him to release natives into the various mist levels and film the results.
Status: Ongoing, but slowly.
Resurrection Investigations
Dead people aren't normally mobile, so he's interested in this as well.
Status: Shelved for the future.
Mist Alterations to Scorched Body
Status: On hold for the moment.
