The following is a list of characters from the animated television series Code Lyoko, created by Thomas Romain and Tania Palumbo.
Aelita Schaeffer (French: Sophie Landresse, English: Sharon Mann), better known as Aelita Stones, is the daughter of Franz Hopper (creator of Lyoko) and Anthea Schaeffer. Nicknamed "Miss Einstein" and "Princess," she is the second smartest of the group, closely following Jeremy. As a little girl, she lost her mother. When a group of suited men came to her home, the "Hermitage," she and her father fled and virtualized themselves on Lyoko. Between the virtualization and Jeremy's discovery of the supercomputer, XANA stole an important memory fragment that inhibited her from becoming fully human again. After this fragment is retrieved, she is no longer linked to the supercomputer. In Lyoko, she has an elf-like appearance, similar to that of "Mr. Puck," a toy elf from her childhood. After becoming human, she often has premonitions and nightmares of what is to come or what was. Until Season 2, she has no defensive capabilities; save erecting a shield wall via her creativity. In Season 3, she acquires the capability to produce small, deep pink-colored plasma orbs called "energy fields" from her hands. In Season 4, she acquires the ability to fly at high speeds with angel wings. However, the ability she has from the start is being able to create and alter the terrain on Lyoko by singing; capable of making a bridge or platform for easier transportation, and defend with a large shield wall. Although on rare occasions, she uses the psionic ability "second sight" to see things made invisible by X.A.N.A. and even sense its presence throughout Lyoko. She is also enrolled as a border at Kadic after full materialization. In order to eliminate problems, they give her the fake surname Stones. When going to the factory, she rides a scooter.
Jeremie Belpois (French: Raphaëlle Bruneau, English: Sharon Mann), nicknamed Einstein and sometimes spelled Jeremy, is a top-of-the-class student who finds and starts the factory's supercomputer while looking for parts to build a robot. 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; Jeremie never goes to Lyoko. When going to the factory, he rides a scooter. He's the main protagonist and also the youngest of the group. Jeremie also has a not-so secret crush on Aelita since he first turned on the supercomputer, therefore revitalizing not only the virtual world Lyoko, but the malevolent multi-agent system X.A.N.A. as well. He seems to be the main archenemy of X.A.N.A. as it appears to want to get rid of him more than the others.
