Tron: Legacy2010

Kevin Flynn:
The Miracle...You remember. ISOs, isomorphic algorithms, a whole new life form.

Sam Flynn:
And you created them?

Kevin Flynn:
[Laughs] No, no. They manifested, like a flame. They weren't really, really from anywhere. The conditions were right, and they came into being. For centuries we dreamed of gods, spirits, aliens, and intelligence beyond our own. I found them in here, like flowers in a wasteland. Profoundly naive; unimaginably wise. They were spectacular. Everything I'd hope to find in the system; control, order, perfection. None of it meant a thing. Been living in a hall of mirrors. The ISOs shattered it, the possibilities of their root code, their digital DNA. Disease? History! Science, philosophy, every idea man has ever had about the Universe up for grabs. Biodigital jazz, man. The ISOs, they were going to be my gift to the world.

Sam Flynn:
So what happened?

Kevin Flynn:
CLU. CLU happened.

[Flashback sequence shows CLU's corruption, and Tron sacrificing himself to save Flynn.]

Kevin Flynn:
It was a coup. Tron, he fought for me. I never saw him again.

Sam Flynn:
So why didn't you fight?

Quorra:
He did.

Kevin Flynn:
CLU fed on my resistance. The more I fought, the more powerful he became. It was impressive, really. And my miracle? CLU saw the ISOs as an imperfection, so he destroyed them.
