Jor El
Jor-El was a member of the Kryptonian Science Council who discovered that the planet and its sun were on the verge of destruction. His warnings to the Council fell on deaf ears, as they considered this to be inciting sedition.Earlier in his life, Jor-El was involved in the sentencing of three dangerous criminals, General Zod, Ursa, and Non, for the crime of inciting sedition against the government and banished them to eternal imprisonment in the Phantom Zone.Undaunted by the ignorance of the Science Council, Jor-El built a star ship for his infant son Kal-El to travel to Earth in, providing a green glowing crystal and an energy module containing the last remaining energies of Krypton. Lara viewed the Earth as primitive, fearing that Kal-El would be a stranger among them, but Jor-El assured her that his son would never be alone. As they watched the star ship rise into the sky and depart from Krypton, the ground crumbled underneath their feet, signalling the death of Krypton.
