Jor-El was a Kryptonian of the House of El and a scientist who prophecized the destruction of the planet Krypton and was not able to convince their high council. He only had time to build one Rocket large enough for his child Kal-El to escape and be sent to Earth, where he was discovered by Jonathan and Martha Kent in Smallville, Kansas; that child would grow up as a great hero to become Superman. His wife Lara Lor-Van perished alongside him when their planet exploded.
