A human or animal that eats its own kind.
These
people don't care who you are, they will just eat you either alive or
cooked. They may put spices on you and then cook you alive.
They appear in post-apocalyptic books or if so, our
earth if it becomes one.
In famines, starving peoples' only source of food is eating others.
Books with cannibals in them, well so far I know that: The Road, is one of them.
The movie: The Road, tells about the book, has a wide perspective of cannibalism being a fear among survivors in a post-apocalyptic world.
Any animal or human or bug(e.g. The
female praying mantis eats the
head of her mate after mating) that devours the flesh of its or her or his kind are considered a cannibal.
A cannibal
may approach to you with their jaws watering and teeth stained with blood. They
may bite you to
death or kill you, you must fight back, kill them or you will be food. Even if you run away, they may outrun you. Unless you get lucky.
