Code Lyoko (2003)

S1E19 Frontier

Jeremie is escalating his "Materialize Aelita!" initiative to unprecedented heights—quite literally. He decides to virtualize himself, but the system lacks sufficient memory to finalize the transfer, leaving him stranded between dimensions. Completing his journey back to Earth requires more memory than the factory can provide. If the team doesn’t act quickly, Jeremie risks being erased as an outdated file! Is this the ultimate challenge for Jeremie? Can Yumi step up and fill the gap?
