Monster
A monster is a type of creature in fiction. They are usually found in legends or horror stories. They are often ugly and may make people and other creatures scared. They also eat people sometimes. A monster could be anything really, like a vampire or a witch or even a werewolf. Figuratively, a monster is a very wicked person. Sometimes these creatures aren't bad or monsters as you would say because some protect other people and/or are inoffensive.
