1. The mentor is a common archetype in literature. The mentor is usually old, and this person often has some kind of magical abilities or a much greater breadth of knowledge than others possess.

 

2. Characters representing the innocent archetype are often women or children. These character archetypes are pure in every way.

 

3. The villain wants to stop the hero archetype from achieving his or her goal. The villain is often evil, though there is often a reason—however warped that reason may be—why villains are so bad. Villains often want nothing more than to control and have power over everyone and everything around them.
