"Yhwach, the world that you desired to create may indeed have been devoid of fear. However, in a world without the fear of death, men could not face that fear and seek out hope. Certainly, they could keep walking onward by merely living, but that would be very different from walking onward while conquering their own fears. That is why we give the act of walking onward a special name. We call it 'courage'."

"[To Yhwach regarding their battle] This is not about benefit. My only purpose has always been to crush all who seek to control me."

"[To Shunsui Kyōraku] I must say... You truly are an entertaining man. Would I like to breathe fresh air, you ask? Would that be the fresh air of a Soul Society being summarily crushed by Yhwach?"

"[To Kisuke Urahara] Those are the words of a defeated man!! A victor must speak not of the current state of the world, but of how it should rightfully be!"

"Seek not beauty in battle. Seek not beauty in death. Consider not your own life. If you wish to protect that which must be protected, then strike while your opponent's back is turned."

"To trust in another is the same as to rely upon that person. Reliance is for the weak. It is of no use to us. It is the nature of all living things to find some being greater than themselves and place their trust in that being, following it blindly. In order to escape from the pressure of that trust, those beings seek a still greater entity in which to believe, and those greater beings too seek still greater, still stronger beings to follow. This is how all kings come to be, and this is how all Gods are born. Do not trust in me yet, Hirako Shinji. I will take my time to teach you the nature of the God whom you face. Then, you shall believe."

"[To Barragan, before he was recruited by Aizen] Isn't it ironic, king of Hueco Mundo? Dressed in black and poised to attack, you look just like a shinigami."

"[To Orihime, after she had being taken from Ichigo once again] A girl like you should smile more often. Overcast skies blot out the sun, and that always brings people's spirits down. So why not let the sun shine...For just a while longer?"

"[to Grimmjow, as the Sexta tries to leave a meeting to hunt down intruders] Grimmjow, I'm thankful for your intentions, but I've not yet finished speaking. Please go back to your seat... Well? I didn't hear your answer...Grimmjow Jaegerjaquez. [Aizen releases an extraordinary amount of spirit energy, forcing Grimmjow to his hands and knees, panting heavily.] I see you understand, Grimmjow."

"No matter what may happen...As long as you walk by my side...There shall be no enemy that can stand before us."

"Good evening, Espada. There has been an enemy attack. But first...Let us brew some tea."

"[After Gin offers to kill some Arrancars] No thanks, for that would be boring."

"No one stands on the top of the world. Not you, not me, not even gods. But the unbearable vacancy of the throne in the sky is over. From now on...I will be sitting on it."

"Thus there were no breakthroughs, as other researchers were bound by obstacles such as ignorance and morals."

"Oh? I thought I severed your body from the waist-down, but...It seems the cut was too shallow."

"In my eyes, there is no difference between wiping away one speck of dust or two."

"'No longer the Aizen you know,' hm...? I'm afraid you've been deluded, Abarai-kun...The 'Aizen Sōsuke' you knew never existed to begin with."

"It's very difficult for me to step on an ant without crushing it."

"Admiration is the emotion furthest from comprehension."

"Don't use such strong words -- It makes your weakness all the more apparent."

"I had no intention of deceiving anyone. It's just that none of you could understand...My true self."

"[To Hitsugaya, after stabbing Hinamori] Aww...You found her. Sorry, I didn't want you to find out this way...No. I should have chopped her into little pieces and hidden them away where you would never find them."

"[To BG9] And you thought I would leave it that way forever? After my battle with Yoruichi-sama, I honed my Shunkō to completion And since then, I have pushed my ability to the limits, taking the technique further still. My Shunkō is "wind". I have perfected a method of causing the Reiatsu I release to flow like a vortex around my body indefinitely. As such, once I have activated my Shunkō, I am now able to maintain it for as long as proves necessary. You have my thanks. If you had not stolen my Bankai, I may never have honed my Shunkō to this level of mastery."

"If you see your allies losing, that's your chance. Don't step between them. Take the enemy down from behind. And if the enemy is so strong you can't even do that, then just watch your ally be killed. That's what it means to be Onmitsukidō."

"I'll show you a real assassination. No...Maybe you won't even be able to see it."

"I thought I told you. If you see your allies losing, that's your chance. Don't step between them. Take the enemy down from behind. And if the enemy's so strong, you can't even do that, then just watch your ally be killed. That's what it means to be Special Forces."

"Of my five older siblings, two died on the first mission, then two more on the second. Then on the sixth mission, the last one... Died as well. I felt sad, somewhat, but more than that, I felt ashamed of their incompetence."

"I'll always be there to fight along side you. I promise!"

"Showing your back in a battle? You've become a fool, Yoruichi!"

"You know the power of my Zanpakutō, Suzumebachi. If someone gets hit twice in the same spot... They die!"

"The one hundred years we were apart were meant to bring me power and make you weak! Yoruichi!"

"Why didn't you take me with you!? Yoruichi-sama?"

"Bankai! Jakuhō Raikōben!"

"Sting All Enemies to Death, Suzumebachi."

"[To Lille Barro] You'd be wise to remember who it is you're talking to... I am Captain Commander of the Gotei 13... Kyōraku Shunsui."

"[To the Gotei 13 regarding his freeing of Aizen] Honor? Is that what you are all talking about? Then let us speak instead of our duty to the Gotei 13. Honor will not protect the world. I do not believe that using evil to defeat evil is itself an evil act."

"[To Sōsuke Aizen] I guess I'm just not much of a listener when it comes to guys. I get bored pretty quickly."

"Only underlings get caught up in matters of style and lose the battle. A captain can't afford such indulgences. Don't try to be a good kid. Whether you owe somebody or they owe you. The moment you start a fight, you're in the wrong either way."

"[To Starrk, about Lilynette] That child with you...Can you send her somewhere else? I can't really go all out with her there."

"I placed this blade of grass in my mouth thinking I'd look cool. But it must be poison 'cause ith makinth ma mouth numb."

"At this point, I'm sure everyone else is far enough away... Nanao-chan, I'm sorry if you get caught in this as well... Bankai. Katen Kyōkotsu: Karamatsu Shinjū."

"Flower Wind Rage and Flower God Roar, Heavenly Wind Rage and Heavenly Demon Sneer. Katen Kyōkotsu!"

"[To Bambietta Basterbine] I have not thrown my life away. I have merely gambled it. Genryūsai-dono gambled his own life on this battle. I see no reason why I should not do the same. From the moment I set foot on this battlefield, I had already left my life behind!"

"[To his great-grandfather] When I was unable to bear the burden of living in shadow...When I abandoned my own family and fled, not caring for the shame I brought upon myself...It was Genryūsai-dono who took me in. That man, to whom I owe the greatest debt, has had his own life cut short at the hands of these Quincy. I have a duty...to avenge this humiliation!!"

"[To Kaname Tōsen] That is why I swore to myself that I would become a true friend to you. If you bore great sadness, I would take it upon myself. If I obtained great joy, I would share it with you. If you strayed from your path, I would scold you. If you made terrible mistakes, I would forgive you. If the world scorned you, I would be your shelter. Somehow, I would give this man who had lost his love for the world the power to love it once more."

"Back then. I felt a kernel of untruth in your words. You talked about "The world she loves" many times. But made not a single mention of "The world I love"."

"[to Tōsen after stopping him from attacking Shinji] It's the opposite of what happened before. I never thought the time would come when I was protecting someone else from you...""

"You destroyed those Menos Grandes. That's enough for me! I have decided to fight by your side! I won't accept no as an answer, masked ones!"
