The wild boar is very well known for its bad temper. They will fight pretty much anything, even each other. Though, you cant blame them as they have so many predators. It is so easy to get a wild boar hunting license that it is almost laughable. Anywhere they go they mate like crazy and quickly become an invasive species, totally taking over their land. And they are pretty common all over the world now; they reside in Asia, Europe, America, and Africa.
