A Yagrum was a rare and dangerous species of creature native to the planet, Krypton. A four-legged monster with a long tail and a tough, purple hide, this species was believed extinct when Krypton exploded many years ago. A renegade Kandorian named Lesla-Lar managed to procure one of these endangered animals and set it loose on the New Kandorian home world of Rokyn where it fought Superman and Supergirl.
- This version of Yagrum (Earth-One), including all history and corresponding appearances, was erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. Even though versions of the character may have since appeared, this information does not apply to those versions.
