"The son becomes the father, and the father the son."

Jor-El (died 1979) was the brother of the late Zor-El, the father of Kal-El, the husband of the late Lara Van-El, and the paternal uncle of Kara Zor-El, as well as one of the most respected scientists of Krypton.


Early life

Jor-El was born on the planet Krypton, into the prestigious House of El. He had an older brother, Zor-El, and they both become scientists after reaching adulthood.

Jor-El fell in love with a fellow scientist named Lara, who later became his wife. In 1979, they had a son, Kal-El.[1]

Project Medusa

At one point, Krypton's ruling advisor ordered Zor-El and Jor-El to create the Medusa virus, a synthetic bioweapon designed to infect and kill any non-Kryptonian life form as a safety mechanism to protect Krypton in case of invasion. To Jor-El's dismay, his brother had no problem creating the tremendous bioweapon. [2]

As their home planet was dying, Jor-El and his wife, Lara, sent their infant son, Kal-El, away from Krypton to Earth.[1]

An ice sculpture in the Fortress of Solitude was crafted in Jor-El's image.[3]

Powers and abilities


  • Kryptonian physiology: Normally, like all Kryptonians, Jor-El's capabilities were no greater than a normal human of his physical conditioning. However, if he had been charged by the energy of a yellow sun metabolizing into his body, he would have become able to perform various inhuman feats. Ultimately though, this never happened as Jor-El was never exposed to a sun different to the Kryptonians' natural red one.


  • Genius-level intellect/Master scientist: Jor-El was highly intelligent, being a well-respected scientist on Krypton and a member of the esteemed House of El.

Behind the scenes

  • In the DC comics, Jor-El of the House of El was a Kryptonian scientist and the father of Kal-El. He prophesied the destruction of Krypton, but was unable to convince the planet's High Council of the impending disaster. Thus, Jor-El was only able to build a rocket large enough to send Kal-El to safety on Earth. Jor-El and his wife, Lara, perished alongside every other Kryptonian when their planet exploded.
    • In Supergirl, Jor-El's discovery of Krypton's fate and subsequent conflict with the planet's government is handed off to Astra and Alura Zor-El.
    • In the Prime Earth continuity, Jor-El was whisked away to Earth before Krypton self-destructed due to the machinations of Doctor Manhattan. Upon witnessing the atrocities of humankind in a war-torn nation, he became Mister Oz, a situational enemy/ally to Kal-El, now Superman.
