After being kidnapped (as shown in Distant Memory) by the men in black on their vacation to the Mountain Cabin, Aelita and Franz Hopper moved to The Hermitage and later virtualize themselves to the virtual world of Lyoko.
Her maiden name was Anthea Hopper. When Waldo Schaeffer (AKA Franz Hopper) changed his name, he took her maiden name. The Project Carthage folder also includes a photo of her skiing pregnant. This gives an idea of Project Carthage's length.
In Code Lyoko Evolution, X.A.N.A's spectre took on Anthea's form and sent Aelita an e-mail, telling her to meet up with her in the chapel. Aelita was so relieved to see her mother again that she did not suspect anything. Anthea gives Aelita an warm hug and starts draining source codes from her. Jeremy soon appears an pulls Aelita away from her and tries to convince her that her mother is a spectre, but Aelita refuses to believe it and runs back to the spectre and hugs it again, allowing it to drain more codes. Jeremy tries to save her again, but this time spectre prevents him from coming closer by attacking. When tower is deactivated, the spectre blows up and Aelita thinks that Jeremy did something to her mother, but this time Jeremy manages to convince her that it was not her mother.
In the fifth season , Anthea is shown to have shoulder-length blonde hair instead of bright, electric pink-colored hair, which Aelita had inherited. It is unknown why her hair color was altered.
In the Episode, Obstination, It is confirmed that Anthea is alive and is working with Tyron. However, it is currently unclear whether she is working for him by force, or of her own free will or blackmailing her abourt hurting her famliy.
