Top 25 Hardest Monster Battles in the Entire Monster Hunter Series

15. Devil Diablos (Freedom Unite)

There is no shortage of annoying bosses in Monster Hunter Freedom Unite, but the least obvious is Devil Diablos, better known as one-and-a-half horns. It shouldn’t ordinarily be so punishing – at least, as far as Diablos goes – but your gear is nowhere good enough to deal with its sheer damage and health pool when it first becomes available. The best option is to return with fully upgraded G Rank armor and weapons. No half measures.
