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. When it sees a hunter, Bloodbath Diablos identifies them as a threat and attacks instantly, sometimes even ignoring other hunters during a hunt, when greatly enraged. While young, Bloodbath Diablos was injured by a hunter, losing its horn in the process. He doesn't speak, so he just watches or screams.
