Kal) appears in Supergirl, through the human vessel Olivia (portrayed by Sofia Vassilieva). In this depiction, Yuda Kal was a Kryptonian goddess of life and birth worshipped by the Juru, the first people of Krypton, but was soon erased with Rao and the ways of science by modern Krypton, becoming feared as a dark, evil deity. The Kryptonian witches (known as Children of Juru) aimed to revive the ancient religion as a revenge against Rao and put an apocalyptic event of coming darkness on their planet. In tribute to Yuda Kal, the witches made a specific mix of chemicals and magic spells to create the Worldkillers using the Harun-El, a Kryptonian metal with magical properties. The Worldkillers (Reign, Purity and Pestilence) were launched during the final days of Krypton when it exploded, landing on Earth, while their creators escaped the destruction on Argo City, which was separated from its planet (with the exception of Jindah Kol Rozz who was earlier convicted on the prison Fort Rozz and later killed by Reign to protect the Worldkiller's secrets). The witch's aim is to ensure that the dark prophecy is fulfilled, specifically terraforming the planet Earth by Worldkillers to make a New Krypton. This ancient teaching found its way through the religious sect "Cult of Yuda Kal", founded by Thomas Colville, in their belief that Yuda Kal would bring salvation on Earth. After Thomas ended on prison, another member Olivia assumed the leadership. In the season three episode "The Fanatical", using Yuda Kal's recipe documented in Coville's journal, Olivia was able to gain powers through an Harun-El statue of the goddess and briefly turned into a Worldkiller-like vessel with the goal of carrying out Reign's deliverance on Earth, but she is ultimately defeated by Supergirl, stripping her powers and Olivia becoming normal human. The fate of Yuda Kal is unknown, following the disbandment of the Cult, the arrest of all Kryptonian witches and the death of all three Worldkillers. References DC Comics characters: Y, List of
