"You never know who you'll run into next."
—Original US TV ad for Kingdom Hearts I
"The worlds are made of Light and Darkness. You can't have one without the other, because darkness is half of everything."
"That's not true! The heart may be weak, and sometimes it may even give in. But I've learned that deep down, there's a light that never goes out!"
"This world is just too small."
"You're wrong! I know now, without a doubt, Kingdom Hearts... is light!"
"Take a look at this tiny place. To the heart seeking freedom, this island is a prison, surrounded by water! And so this boy, sought out to escape from his prison! He sought a way to cross over into other worlds, and he opened his heart to darkness."

Hades: Let's cut to the chase. Here's the deal I'm gonna offer you. I'll let you out of the slammer - no strings - you'll be free as a bird. And all for one little job: fight Hercules, in the Coliseum, to the death!
Hades: Did you forget who you're talking to?! I am the LORD OF THE DEAD!

"When he sees the heart in something, it then becomes real. When a connection seems broken, he may have the power to mend it. He has touched countless hearts, he has accepted them, and he has saved them. And some of those hearts have never left him- whether they fell into darkness or were trapped there- whether they sleep in the darkness of Sora's heart, or were welcomed into its warmth- they can be saved. All Sora needs to do is be himself and follow wherever it is that his heart takes him."
