It may seem redundant at first as strictly speaking an archetype is simply an example of something, in short every trope is a story archetype. However here we are using the term in reference to a concept in Jungian Psychology of the same name.
An Archetypal Character
is a character who appears over and over in legends far and wide, even in cultures that have shut themselves off from the world. The blood drinking risen dead
are an Archetype
as almost every culture has come up with their own legends independent of each other. Angel
is an archetype: the tragic hero trying to overcome the evils of their past. Coyote
is an archetype. Xena is an archetype. Any of these may be disguised as a Space Alien
Some lit-theories classify archetypes by the role/purpose the character inhabits for the story. These classes are: Protagonist
, and Contagonist
A related concept is the 'ectype', a distorted or flawed version of the archetype. For example, Batman is archetypical. He's a rich man who dedicates himself to anonymously fighting crime (protecting society) with a variety of gadgets. Many of the characters in Watchmen
are ectypes based on this archetype.
