I have translated the French version of the Code Lyoko theme song into English, and I found it completely different from the English version:
There is a world, virtual and different.
Each second, it's true that we're combattants.
Our sole hope is to reprogram it all.
Chorus 1:
One will go, one will know to save our existence.
To provide a chance to erase it all.
One will go, one will know to save our existence.
To reform
a world without danger.
Chorus 2:
Code Lyoko Reprogram it all.
Code Lyoko A world without danger.
Code Lyoko Reprogram it all.
Code Lyoko A world without danger.
All is numerical and pixellated in that world.
We will need courage and assistance.
But you say well that one risks our lives.
Repeat Chorus 1
Repeat Chorus 2
One promises to you to give the maximum
against the menace and to save all humanity.
Repeat Chorus 1
Repeat Chorus 1
