Temporal Paradox.
Episode Description:
During a training mission on the Cortex, the Megapod bugs up and Jeremy is forced to figure out how to repair it. Just as he does so, the superscan finds an activated tower on the Cortex. But when they arrive on site, they find the tower has a purple halo. It has been activated by Tyron, and the Lyoko Warriors are soon surrounded by Ninjas, and Odd, Aelita and Ulrich become trapped in a temporal bubble that sends them back to that morning's gym class, repeating it dozens of times over. They must find a way to contact Jeremy to tell them what happened so that he can destroy the bubble before Tyron uses its signal to track their location on Earth...
