Franz Hopper, Aelita and others in “Unfinished Business”

That X.A.N.A. Locks the door but leaves the window wide open.

But...who are you?

What? Haven't you understood, yet? I'm Franz Hopper. I'm the one who created Lyoko, and X.A.N.A. too. But then I lot control of it. In the very beginning, it was program that I designed to counter a military project based on a multi-agent system.

What about me?

I created you to be the guardian of Lyoko. But I never thought I'd see in flesh and blood.

Ulrich
