The whole point of Capcom's Monster Hunter series is to fight screen-filling creatures of all shapes and sizes, but for the most part, those creatures aren't spiders (or spider-like). The one exception is the enemy Nerscylla, who debuted in Monster Hunter 4 but was nowhere to be found in Monster Hunter World. There is, of course, a reasonable explanation for this: spiders are creepy. Worth of respect? Sure, but from a distance—a long distance. And who wants to fight a giant spider over and over again for more weapon and armor parts? Not me.
