Oh great as a matter of fact ghost channel is my favorite too but for different reasons. Them being trapped in a simulation bubble and jeremy rescuing them really intrigued me and when they chose the real jeremy because of the emotion stuff i wached that episode like for 6 times :D
Yeah, I love Code Lyoko. My favorite episode is Ghost Channel because it's the only one that you can hear Xana's real voice in clearly. Xana is a great villain. He has a lot of character development even though we never see him.
