User blog comment:Lord Loss/Monster Hunter Theory... Blog/@comment-74.193.207.108-20120817183402

Here is something I've recently realized about flying wyverns like rathalos, rathian, gurenzeburu, and berukurosu is that they really can't afford getting into very physical altercations with land based monsters such as bracchidios or kuarusepusu due to their wings. These creatures wings ensure their very survival and if something were to cause serious damage to their wings they would be up a creek without a paddle. If a rathalos can't fly then it can't hunt and if it can't hunt it will most likely die of starvation and could become possible prey for large predatory land based monsters like zinogre or deviljho. Evidence of this is seen in Tri's cinematic opening where a rathalos retreats from a lagiacrus and in the Frontier benchmark focusing on dyuragua where it forces a berukyurosu to make a quick and hasty retreat.
