oh my god i thought princess mononoke was an exaggeration
Escaped domestic pigs rapidly shift back to their hairy, tusked roots in only a couple short generations after escaping captivity. Boar with that kind of feral pig ancestry can be absolutely enormous, because the domestic pigs are bred to grow as large as possible. So you end up with animals that are meant to grow upwards of 2000 lbs in ideal situations mixing their genes in with the feral populations, creating a handful of animals with the potential to grow to bear-like proportions. Obviously hunting photos are shot as flatteringly as possible to exaggerate the size of the animal, but stories of the rare wild pigs tipping the scales in the 1000 lb range are not unheard of.
