It is utterly impossible to make a blos-type monster bad. Both Monoblos, both Diablos, Varusaburosu, probably Bloodbath Diablos (I haven't unlocked it yet), it's the perfect monster. Wilds is made worse by not having a blos, real life is made worse by not containing a blos. If you looked in a textbook under "peak monster" you'd see a picture of Monoblos dancing.
