(written from a Production point of view)
Jayden was a character from a Barkonian story mentioned in the script for the Star Trek: The Next Generation episode "Thine Own Self". He was a handsome nobleman who was put under the spell of a demon. The spell transformed him, making him look different from everyone else. Yet as children were mean to him and laughed at him, Jayden never became angry. In 2370, an amnesiac Data was named after this character by Gia.
