Syfy and Warner Horizon TV have teamed up with to produce "Krypton" which will a one hour drama about Superman's/Kal-El's grandfather Seyg-El. According to DC comics character database, Seyg-El was a member of the House of El and a leader of the Kryptonian science council.
The series will be set during a time when the House of El which is one of the royal families of Krypton is ostracized. This is an opportunity for the writers to further expound on the little most people know about Kryptonian culture. For example marriage partners were chosen by the Master of Gestation Chamber (Genesis chamber in Man of Steel). It is also an opportunity to explore the father son relationship between Jor-El and his father.
Seyg-El in the comics had one weakness, he could not leave the planet to go to space. This was due to a genetic defect that would cause him to have a seizure and die if he were to make the trip.
In the comics Seyg-El wore a bio suit that gave him nutrients slowing the aging process. He also had several robotic servants such as Kelex and Kelor.
