Apocalymon: The time has arrived. And at long last, we see before us the great collection of hearts to the Human World. Hearts full of rage...hate...sadness... and bliss. Shining down upon us is the crystallization of all hearts- Kingdom Hearts. There, in the sky, hangs in the promise of a new world. My friends! Let us gain further power to conquer the Digimon and Human heart, and claimed it as our own. Let us remember why we are here and what we hope to achieve. Hearts shall be gathered, and be made our own. Hearts shall never again have power over us.

They were at the Tower of Digital Twilight Town
Veemon: Yeesh. All this fighting stuff... I wonder what they are for?
Impmon: Aw, come on, you know what it's for. We have to complete the great Kingdom Hearts. You saw it already, right?
Hawkmon: I know. But what is Kingdom Hearts?
Agumon: I... think it's the gathering place of hearts... isn't it?
Impmon: It's where all the hearts wind up after they're released by you. When we gather enough, we might finally get hearts of our own.
Agumon: Hearts shall be made our own...
Veemon: Is Kingdom Hearts really that important to us?
Impmon: What are you, a Knucklehead?
Veemon: I just don't see why having a heart is that important, of course.
Impmonn: Oh, come on, you're wondering about that now?
Veemon: Well, I don't understand since we don't have a heart but only data.
Agumon: Veemon...
Impmon: We'll understand once we have our own hearts. that's why we fight, to find out what it's about.
Dorumon: Alright. I hope you're right, this time.
