Maybe the reason fatalis is dangerous May be due to the habitats it lives in. Fatalis is often pictured in plains. Plains usually have grass, right. And fires are known to burn grass. So it maybe able to burn down a grass land, forest or a town. So how can it burn a mountain with no grass. Well, the areas in MH universe are very similar to violet phosphorus which is also flammable.

Also, when the crimson fatalis expels fire from the mouth, due to being a few flammable objects , the fatalis has a larger spread of fire than its brethren.

Fatalis live near man-made structures right? So it could be possible it decimate the population. Don't believe me? Well, reptiles like Crocodiles and the infamous Komodo Dragon have been known to go for food for weeks and even months. So, if we assume, that a caiman 5m long can go for 2 months without food.

Then it is possible for a dragon standing at 15-20m can go for food without food for an infamously long time of 6-8 months without food. And if there are larger fatalis then they may go for food for around a pretty long time and it is bound to come across a carcass take for instance one of a Lao that is around 50-60m long then it would add to the total of time a fatalis can survive without a food.

( The total = 8 (15/60 = 3 over 4 ) 8x3x4= 96 months. That's That's eight Years ..... Years)

And let's account the humans it could have ate.

( 2m x 1000 ) Take in consideration that the town has 1K and an estimate human size. So we will be using a scale of sense by using a crocodile species ,so, a saltwater crocodile can go without eating for weeks (E=6) so if an animal around 3x the size could have gone without eating would have last 18 weeks or around 4 months. But we have to consider it's scale (= 24m) so 24-18? That would give us 6. Divide by 3 and that would give us 2. And we multiply it by 2000 and that would give us 4000 days and approximately 15-16 years add that to our previous calculations and that gives us with a maximum of 24 years.

So maybe not as high as it's years (Considering it has to do the whole process 4 times ) but I might have has a mis-calculation or if a town it ravaged had more than the amount it would end up differently.(Then we would have to calculate the population etc.).
