What Is A Monster?

That depends on what you are thinking might be a monster, because there are monsters in the movies and in books, even pictures, they depict a creature of some kind, and are usually ugly or gruesome to look at, very scary looking, or odd looking, something that isn't in our normal world.

On the other hand, if you are talking about people that is another story. There are human monsters all over the world!! People that love to hurt other people, for whatever sick need they might have. Like Saddam, or Hitler, at the top and then the individual man, who is a monster up close and personal.
Hope this helps.

Monster word usually refers destructive creatures including Animals(Dinosaurs etc) and even Humans(for their emotional and physical destructive nature).

Anything not human or animal like me for example!
