Compared to a normal Diablos Bloodbath Diablos has more physical strength and fights more aggressively. Despite its large frame, it can turn and charge at a foe with incredible speed, and devastate any unprepared opponents. When angered, red flame-shaped 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. When like this, it can also change directions during a charge without stopping
