Unlike all other Bots, the Beastlords are mortal beings. Their code is not separable from their bodies. They are also unique in that their bodies are not made from any substance known to man or Bot. They are extremely strong and long lived.
Throughout the many millennia Beastlords have been on Earth they had faded from the memory of humanity into vague legend. Although still rarely seen even during the Bot War. There are ancient archaeological scripts recounting brief interactions between humanity and the Beastlords. These ancient texts describe giant dragon like beasts capable of spewing flame from their mouth or crushing whole towns with the sweep of a giant tail.
