In the early 1980s there was a U.S. TV show aired on Dutch television that I want to track down. (Show might be from late 1970s; it usually took a few years before things showed on Dutch TV back then.)
I never saw much of it as it aired in mid-afternoon, before I could get home from school. As I recall it was only 1 season, maybe not even a whole season.
The main character is a 15 or 16-year-old teenage boy who is actually an alien prince. After a coup/war on his home planet killed his father (which took place when he was very young), he was brought to Earth by his mother (or nanny, I never figured out the actual relation).
He tries to live a normal life with his mother (or nanny posing as mother), but agents from the enemy alien government are still looking for him. Some Earth government agencies are also interested in him because of his psi powers that develop as he grows older. I recall he had telekinesis, telepathy and some form of remote sensing. The "mother" doesn't have any special powers, if I recall correctly.
The U.S. Air Force knows about his presence and he has an Air Force liaison officer (a black guy if I remember correctly, but I may be mixing this up with "Chappy" from the Iron Eagle movies). Occasionally the Air Force asks him to use his psi talents for a Specials Ops sort of thing.
In the TV show he has a high-school sweetheart who eventually discovers his secret and gets involved in his adventures too.
I vaguely recall that the young man has a mark on his forehead (possibly star-shaped) that is normally invisible but that can glow. (When he uses his psi powers?) This mark is the sign that he is the true heir to his fathers kingdom.
