Who killed aizen?

Answer 1

Ok people been hearing many different answers like Gin killed Aizen but... it wasnt him

The real person the killed Aizen was Ichigo (I wouldn't be surprised) there was a duel between them as Aizen almost killed Gin with one blow with his sword then Ichigo stepped in before Aizen killed this other soul reaper (haha sorry don't know her name) after Ichigo set down his dad on the ground Ichigo wanted to make a deal to fight somewhere else then where there is a whole lot of people but Aizen said no after Ichigo grabbed Aizen by the face flew in the air found a far spot from everyone and throw him at the ground after that they talk for a little then they faught Aizen swing his sword at Ichigo but he block it with his and a huge rock just slice in half and evaporated in the sir Aizen taught that was his sword but Ichigo told him the true that the rock that evaporated was from his sword... Ichigo flew to Aizen and hit him with his sword and it damage him pretty bad but Aizen turned in a full hallow creature thing and tried to kill Ichigo but Ichigo use his newest move "The Final Getsuga Tenshou" and Ichigo was the move was Ichigo's hair turn really long and black Ichigo used the move sliced Aizen in half but to do the move Ichigo would have to loose his soul reaper powers! Itchigo lost his powers and Aizen was still alive but Badly injured by Ichigo's blast then Ichigo's teacher (forgot name also but he has 2 children living with him with a cool hat) stepped in and put a seal on Aizen after the seal took effect Aizen died.

So Mostly Aizen died from Ichigo and a little of his teacher help too.

Well, from all the episodes i have watched Aizen is not dead. But it might be Toshiro or Ichigo.
