"The gaze into the sun." - Tite Kubo
Sōsuke Aizen (藍染 惣右介, Aizen Sōsuke) after 20,000 years of nothing but waiting, is a changed man. After being banished from Soul Society by the Royal Guard, Aizen is currently using the Arrancar army he created, to do the same goal he had last time: Be a changed man.
Because of the Hogyoku's power lingering in Aizen, upon arriving in Hueco Mundo, his appearance reverts to the Hogyoku's second form. It stays this way throughout the series, except for Aizen's eyes changing to his original brown colour whenever he is injured.
Now though, Aizen possesses a much more calm personality, as he believes the Nuevo Espada are the ones to gain him what he wants: A true army.
