Code Lyoko Hopeater edition: The Professor and his family
The Professor is the creator of the Calculator and everything within it, X.A.N.A. included, for purposes unknown. A scientist who was as brilliant as he was mad, he seems to have completely vanished from reality. His notes on the Calculator are as much about the different programs and functions as they are mad rambling about shadows that are following him. His wife, a former soldier, disappeared some time before him and was a major contributor to his going mad, and the whereabouts of his daughter, who would be in her thirties now, are unknown.
There is a framed picture of the three of them, bundled up for the winter, near the screens of the Calculator. There is a copy of it in the files of Lyoko’s heart.
