Cromag was a large humanoid beast "owned" by Mosh Pelkan. He was two and a half meters tall, with huge eyes with overdeveloped shoulders and arms. He was described as having a shape like a "V". He was the primary combatant in the gladiatorial arena at Pelkan's Mansion on Questal. Many of his opponents were prisoners of the Imperial Moff Bandor whom Pelkin served. On one occasion he fought and killed a Gamorrean and Wookiee simultaneously in the arena.
