Jeremy Belpois
A 12-year-old (later 13-year-old) top-of-the-class student who finds and starts the factory's supercomputer while looking for parts to build a robot. By turning on the Supercomputer, he reawakened Aelita Schaeffer, the virtual world of Lyoko, and the malevolent multi-agent system XANA. His goals are mainly driven by his desire to protect Aelita, whom he has a crush on, and to save her from the Supercomputer and XANA by materializing her on Earth. As part of the group, he specializes in programming new ways to defeat XANA and monitors the group while they are on Lyoko. Because he is not very athletic and is more computer savvy, Jeremy almost never goes to Lyoko, only going there once and vowing to never do it again. His workaholic attitude occasionally puts a strain on his relationships with the other members of the group.
