The Ketrann was a dangerous carnivore native to the Outer Rim Territories planet Alk'Lellish III. Described as "huge and snarling," the Ketrann had four long, white fangs. It fed on migrating herds of Metarshi, which it killed by leaping onto the Metashi's back and biting it once through the neck. Wilek Nereus personally killed one once and hung its teeth in his office on Bakura.
