Well, Iyce Ex put a review in that mentioned I may want to give a certain someone a shot in my story. Personally, I believe it came out awfully. It's very hard to try and capture the essence of the only Nobody who truly had no emotions. In my opinion at least. Here we are, though.
Thank you Auron's Fan for pointing out the errors in my quotes!

I Wonder Why… I Will Never Stop?

No emotions, no hearts, nothing. Just pure, cold logic. Let the lesser ones believe what they wish, we are the perfect beings because we have no morals, no scruples that can stop us from reaching our goals with ceaseless perfection. Yen Sid, he warned the Keyblader in the beginning that out hearts are gone, no matter how much they may appear to still exist. This is solidly true, no matter how much the Witch wants to believe otherwise. Her words are simply an attempt to bring our downfall, and she will be destroyed soon, just as soon as it becomes necessary.

For now, I'll hold her captive here, because without her, our perfection will never be reached, and my Kingdom Hearts will never grant me the interminable glory that I, and all my predecessors, have struggled for. Ansem the Wise was but a joke, though he attempted valiantly, he was weakened by the heart that told him not to meddle, as was Xehanort. And the Ansem who was my other? Hah! He was nothing but a heart! His attempts were doomed from the start. I, however, am the product of decades of study, the perfect scientist of hearts.

I can and will understand their secrets, for I am an outsider, with no predefined notions or prejudices wrought by a heart of my own, save that the heart is the source of all their power, and it is obvious that is true. After all, even the Keyblader became nothing but a Shadow when his heart was taken, yet the Nobody he left behind! All the boy's strengths and none of his weaknesses!

It is a pity XIII left us. Had I a heart, I would almost be saddened by the fact that I will have to destroy him for joining the Witch in her goals of the Organization's destruction. And he convinced VIII betray us as well, though the Flurry of Dancing Flames took longer to leave. But, it simply proves further my point. The Keyblader, Sora, would have been able to make his so-called friends follow him into the depths of oblivion, he already has, actually. And so, Roxas could do the same. Every ability, yet many times stronger than the heart-filled boy.

And the one who calls himself DiZ, does he really believe I do not see him for what he is? The first failure of my lineage, one that should have been abolished by Xehanort long ago. He will become troublesome soon, but he will be his own demise, just as soon as the King reaches him again. For the time, I shall let him believe what he wishes. If that includes believing he can be my downfall, then so be it.

My grand Kingdom Hearts is near complete, now. And in moments Saïx will come to me, asking if he may finally be granted a chance to-

"Is Kingdom Hearts complete?"

"Very soon."

"Then, I may drop this illusion?"

"Indeed."

You see. I know my underlings well. Saïx will go forth and fight the Keyblader; he will fail. DiZ will show himself, and the one parading as my other will be given his true form. They will think my Kingdom Hearts is destroyed, but it will not be.

As I said, I am the perfect scientist of hearts. I know every move these emotionally driven creatures will make, and I will be able to counter it. Then, then I will have the perfect heart, one that I created, that shall listen to me more than I listen to it. I will outdo all of them, and I will be known forever. The nothingness eternal.

Someone, one day, will wonder what I want a heart for. They will speculate that I truly felt the need for one. I am above need. I feel nothing. Even if the underlings have echoes of emotion, I am past that.

I am driven solely by the causes of my creation. Until I have mastered the heart, I have no other purpose. A puppet to Xehanort's irrational desires, perhaps, but I am stronger than any of them, and when the Keyblader and his foolish friends attempt to defeat me, they too will see. I am not that simply destroyed.

Light is forever, dark is endless, and I am eternal.
