The seventh season of Code Lyoko is a project for fans and the continuation of the season 6, and this is the second season created by Rex Salazar.
The seventh season is focused on a new villain stronger that X.A.N.A. named "Baron of the Illusions". It begins roughly two months after the season 6 from Yumi's disappearance who is tortured by the spectres formed of Takeo and Akiko Ishiyama. It's prophesied about the end of the world and the Doomsday by another person different than X.A.N.A. and still without determining. Also they appear new mysterious characters, like Juno, and return the sentinels to replace the X.A.N.A. monsters. The season concludes with the destruction of the Factory and the arrest of the Lyoko-Warriors by the FBI putting their future in danger. The Lyoko-Warriors faces a future uncertain for each one.
