Code Lyoko, Season 1

Yumi:
Hi. Find anything?

Jeremy:
Yes. X.A.N.A.

Odd:
X.A.N.A.? What's that?

Aelita:
A super dangerous program, like a virus that can control electricity and it activates towers on Lyoko to gain access to your world.

Yumi:
So the red tower, the electricity monster, the monsters on Lyoko- All of that was X.A.N.A.?

Jeremy:
Yes. Only Aelita can counter it by deactivating the tower that it uses for attacks in the real world.

Aelita:
No, Jeremy. We better just shut his thing down.

Ulrich:
Look, we know how to neutralize X.A.N.A. We just get Aelita to the activated tower.

Odd:
And we can fight off the monsters while Einstein figures out a way to bring Aelita to Earth, right?

Yumi:
It's risky, but I think we should. After all, we are Lyoko warriors, aren't we?

Jeremy:
All right. Don't forget about our pact, right?

Yumi:
Relax. We all know how to keep a secret.
