He did not get defeated by aizen, he lost to his own power. Or more specifically the plot as he ain't the main character so he's not gonna beat the villain. Yama also didn't need to even release his zanpakutou, he could kill aizen with his bare hands. Also ryujin jakka was more then enough to deal with aizen as well. In the original Bleach anime, Aizen turned out to be the biggest antagonist after he tricked the entire Gotei 13 in an attempt to create the King Key to enter the Soul King Palace. While a lot of Very intimate if you ask me. Aizen's using very intimate language in that letter, after all. There's also the fact that even after he had stabbed her, Momo was proclaiming how she thought Aizen was innocent and that Gin was putting Aizen up to what he was doing, as well as naming him Captain Aizen when she showed up int he Winter War. I think this has recently been contradicted by the novels and was definitely not presented as such in anime filler (like in the anime version of Aizen meeting Barragan), but my understanding from how it was discussed in the manga was always that Aizen's ritual to put people under hypnosis was this really long and complicated affair, given how it's described as a hypnosis ritual. 4 She's Perceptive. Unlike the blockhead Yammy and the overconfident Aaroniero, Halibel is a witty and perceptive Espada, much like Stark and Ulquiorra are.

Aizen was a bad guy, but he wasn’t evil as the action was justified by the means. An example of an evil being is Ichibe. Cause if you read the novels you know how fucked up he is.

Aside from personal revenge, Gin likely had an yet another reason for following Aizen. When he attacked Aizen, Gin mentioned that he was the only one who could kill Aizen, as only he knew the Reaper's weakness. Perhaps Gin knew right from the start that Aizen would become a much larger He manipulates her in the first place to fall in love with him and be completely and mentally dependent on her He tries to make her kill herself in combat by first manipulating her into attacking Gin/Kira, and then by pitting her against Hitsugaya The Fake Karakura Town arc begins when Aizen and his three main Espada —Coyote Starrk, Baraggan Louisenbairn, and Tier Halibel enter the real world, together with their Fracción. Starrk is forced to include his other half, Lilynette Gingerbuck, in the battle against the overwhelming Shunsui Kyoraku, but this plan fails miserably. Momo Hinamori (雛森 桃, Hinamori Momo) is the lieutenant of the 5th Division, formerly under Captain Sōsuke Aizen and currently under Captain Shinji Hirako. Momo has brown eyes, and wears standard Shinigami shihakushō, with her black hair pulled into a bun held in a tied cloth. When in her Shinigami robes, she wears the 5th Division's lieutenant armband. While in her pajamas, a plain Aizen, like Shinji, know that their subordinate will come after him, but they take a different approach.
