Code Lyoko: Evolution

"The rogue artificial intelligence/multi-agent system, X.A.N.A., makes an unexpected return after one year"

"Lyoko is fully reconstructed in the digital sea, but the Forest and Ice regions are lost due to the long inactivity of the supercomputer"

"Yumi, Odd and Ulrich are now capable of deactivating towers, due to having X.A.N.A.'s source codes inside them."

"Ulrich uses his special ability of super sprint."

"William Dunbar is welcomed back as the fifth Lyoko Warrior."

"Aelita's presumably late mother, Anthea Hopper, is revealed to be very much alive, in some unknown part of Switzerland."

"This episode has the exact same title as the fourteenth episode of its 2D animated show, Code Lyoko."

"Anthea Hopper comes to shocking realization that the daughter she had believed dead is very much alive."

"The Scyphozoa ensnares William, enabling X.A.N.A. to partially possess him again."

"Aelita's "birthday" is celebrated here since she could not recall when she was born, Jeremie told her to choose one. But, she had asked him to choose for her, which would be a surprise, in Episode 78 "Lab Rat.""

"Only Yumi and Aelita still have source codes inside them, leaving X.A.N.A. at 95% of his strength."

"This season finale has ended on an unresolved cliffhanger, leaving many things left unresolved:"
