Traditional depictions of Zor-El in Golden Age and Silver Age DC Comics stories portrayed him as a benevolent scientist concerned for his daughter Kara, acting similarly to his brother Jor-El in sending his child to safety on Earth. In the mid-2000s, DC experimented with different characterisations of Zor-El, even briefly casting him as a mad scientist with a grudge against his brother. A similar depiction was used when the character was adapted for television in the series "Smallville". In 2010s stories following DC's The New 52 reboot, Zor-El has been an antagonist for Supergirl and Superman, having been transformed into the villain Cyborg Superman by Brainiac.
