none of the deviants, much less diablos, have anything to do with the village quests. i would say that bloodbath has the most history to it in game, though. that aside, the whole "deviant" system was designed to rework preexisting monsters in a way that would make even a normally easy monster species difficult to fight, even for long-veteran hunters. people loved the challenge the deviants in MHgen offered in multi-player hunts, so capcom pushed bloodbath as the final, mostpowerful deviant there is.
