After one of its horns was broken off, a new but severely warped horn grew in its place, while its other horn grew to a massive size. Bloodbath Diablos also has bluish blood covering parts of its body, including its face, wings, and tail.
Compared to a normal Diablos, Bloodbath Diablos has more physical strength and fights more aggressively than a basic individual. When angered, red veins will appear on some portions of this individual's body. However, it has another enraged state beyond its first one. When greatly enraged, Bloodbath Diablos's secreted body fluids will begin to evaporate due to its intense body temperature, causing a sort of steam to spread off its body. The evaporation of the body fluids causes a steam explosion, which can easily push off foes that are near it.
Like Diablos, Bloodbath Diablos is highly aggressive. However, Bloodbath Diablos is described to be quite rogue when it encounters an enemy, especially if that threat is a hunter.
A desert legend tells of the brave armies sent out against the unimaginable cruelties that had besieged their cities and nations. None of them returned alive, and only the sands remained as witnesses of their efforts. This story has no hero or happy ending, only the wyvern known as "Bloodbath". Requires special permission to hunt.
