Venators were very large reptilian creatures, and possessed a large metallic shell. Bioengineering on the part of the warlords of Yavia resulted in a massive increase in the amount of metal plating on the average Venator. Venators were most commonly 10 to 15 meters long, wide and tall, and due to their heavy armor, weighing up to 60 tonnes. Some massive specimens were up to 25 meters and weighed up to 100 tonnes.
