Jor-El (1935-1986) was the Kryptonian biological father of Kal-El (as both Clark Kent and Clark Luthor), as well as the most renowned scientist on Krypton and an influential member of the Science Council. He and his brother Zor-El were the sons of Seyg-El. When he was in his 20's, Jor-El travelled to earth by the name of Joe (regularly called Joe the Drifter). Before his death, he cloned a powerless version of himself and placed it in the Orb, and also copied his brainwaves into his son's spaceship, creating an artificial intelligence that often serves as Clark Kent's guide on Earth.
