Childhood
Born in 2511, Jonathan was created by Doctor Catherine Elizabeth Halsey using a modified version of Halsey's own genetic structure as part of an off-the-books experiment to create a child with no imperfections. The initial experiment was an unparalleled success, convincing Halsey to repeat the procedure, this time crafting an exact clone of herself, right down to the high-functioning autism that Halsey had suffered from as a child. Jonathan spent his first two years in Visegrad with his mother and sister.
