Yagrum

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.
