On their native planet, Diablodons are considered to be the ultimate predator. They are descended from the reptile strain of midasaurs. While some midasaurs have been domesticated by the people, many more are not. These range from the small and virtually harmless species, to the massive Diablodons themselves. Found scattered across numerous worlds within the Jericho Reach, Diablodons have been distributed by many Rogue Traders and Free Captains for a variety of reasons: some deliberate and others by accident. They feature popularly within many of the legendary Beast Trades and tournament arenas for obvious reasons.
