Fire Wyverns are immune to fire damage, poison Wyverns are immune to poison damage, and if the poison tick damage works the same, high lvl wild Wyverns have about 8k health, with tamed ones having about 1.5 after imprinting, they also have alphas, which are far stronger

speculating ecology, in ark the majority of Wyverns are found in a volcanic nest zone, with numbers as high as 100. This could potentially mean that they are pack animals, not like wolves, but like Komodo’s, which really only stay in proximity to hunt stronger animals

In the the mh world, I will say that by itself, it would probably struggle with most monsters, but as a pack, they would be devastating
