"Ichigo Kurosaki, all of the battles you've fought, were all part of my plan."

"It's impossible to feel exactly the same as someone else... but when you both care for each other, your hearts are able to draw a little closer together. I think that's what it means to make your hearts as one."

"I didn't come here to fight! I came here to hack at you violently!"

"[upon arriving at Szayel Aporro Grantz's location] Arrancar, Arrancar, Arrancar... Espada! Hueco Mundo is quite the treasure trove."

"[to Szayel Aporro Grantz] Immaculate being... Was it? In this secular existence, perfection is an illusion, regardless of those who utter the contrary. This is the reality. Common man seeks it out, they strive to achieve it, as if it were some tangible thing... But... The fact of the matter is, perfection is a hollow shell. It is devoid of any substance. I spit on perfection. Perfection, after all, implies you've reached the summit. No trial and error, no ability to conceptualize. An omniscient being would have no need for such superfluous things... Am I making myself clear? For people who dabble in the sciences, such as ourselves, perfection would make us obsolete. Many magnificent things have been, and will continue to come into existence... And yet every last one of them will fall short of perfection's finish. Our function as men of science relies on their many shortcomings. Then, and only then, can we apply the fruits of our labor. To put it simply... As soon as you began spouting that nonsense about being an immaculate being... your fate was sealed. How dare you call yourself a man of science?"

"Oh, you know what I'm talking about. That stupid line that all you Quincies keep saying up until the moment you die. By the honor of the Quincy I cannot do this, by the honor of the Quincy I won't allow that. Quincy this, Quincy that! Every last one of you! It's so annoying!"
