alias Aelita Stones, Aelita is the smartest of the group alongside Jeremy. At the beginning of the series, she was trapped within Lyoko, inside the Supercomputer. She was originally thought to be an AI until it was revealed that she's the daughter of Franz Hopper, the creator of the world of Lyoko. As a little girl, she lost her mother. When a group of suited men came to her home, she and her father fled and virtualized themselves on Lyoko. Between the virtualization and Jeremy's discovery of the Supercomputer, X.A.N.A. 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. After becoming human, she often has nightmares of her past life. She later enrolls as a boarder at Kadic under the alias Aelita Stones, claiming to be Odd's cousin. She reciprocates Jeremy's feelings for her, but he often strains their relationship by overlooking Aelita and her passions in favor of working on the Supercomputer. Aelita is the only one capable of deactivating towers on Lyoko to stop X.A.N.A.'s attacks. On Lyoko, she has an elf-like appearance, similar to that of "Mr. Pück," a toy elf from her childhood. She has the "power of creation": the ability to create or remove objects, such as rocks or bridges, from the virtual environment. She had no weapons or defense until season 3 of the show when she developed the ability to use "energy fields," pink balls of plasma that can be thrown or used to block enemy fire. In season 4, Jeremy programs light pink angel wings as part of her new virtual attire, allowing her to fly and carry one other person. Odd Della Robbia Voiced by: Raphaëlle Bruneau (French); Christophe Caballero and Matthew Géczy (English) The comic relief of the group. Odd is credited as having great potential when it comes to school, but rarely uses it, and as a result of this, he gets bad grades due to his lack of studying. He shares a dorm with Ulrich and has a dog named Kiwi, who he hides in a dresser because pets aren't allowed at Kadic. He's considered a ladies' man and has dated many of the girls at his school, but his romances tend to last only a few days. Before he attended Kadic, he lived with his parents and his five sisters.
