I like mentor characters.

This is not just me of course; the mentor and protagonist relationship is powerful. Some of the best moments in many stories are the first encounter with the mentor, the training and sense of discovery for the protagonist, and the eventual loss of the mentor character (they often die, or at least are not able to help when the protagonist faces their final challenges in a story).

When the mentor dies it's often the most memorable moment in a story.

Maybe we dig them because they know a lot of stuff, and have strengths that are germane to the type of story being told.

In certain genres, they're really badass. Or they're wise. In other genres, they're cooler than the protagonist, who still has a lot to learn.

My top five fictional mentors (or the ten that come to mind at this second):

-Aahz, the mentor to Skeeve in the Myth Adventures books by Robert Asprin. Aahz is hilarious, a bit nasty, and one of my favorite characters ever. Just as a mentor should be, he's absent at crucial moments in most of the early books.

-Wade Garrett (Sam Elliott) the ass kicking bouncer and mentor in the movie Roadhouse. So cool! This is probably my first exposure to this type of character where I began to recognize the mentor's function in a story.

-Sean Maguire (Robin Williams) in Good Will Hunting. The mentor relationship is important in that movie. There is also another mentor for Will: Sean's former friend Jerry (Stellan Skaarsgard). Having two mentors can be an excellent way to give a protagonist an inner conflict and decisions to make. The mentors represent different paths the protagonist can choose.

-Stick (Scott Glenn) from the Daredevil series. Super cool. In the Wade Garrett mold.

-Fletcher (JK Simmons) from the movie Whiplash. This is the story of a very challenging relationship with a mentor.

(I actually put Fletcher in there instead of Pai Mei from Kill Bill. My mentor choices seemed too similar).

Of course, I also dig the traditional wise mentors like Gandalf, Obi Wan Kenobi, and Furious Styles (Boyz in the Hood). Doc Brown from Back to the Future is another one. There are so many!

Some mentors can be “false mentors”. They betray the protagonist or let them down.

What kind of mentor characters to you enjoy? Is the mentor a vital part of many stories? Is it just a cliche? Do you use mentor characters in your stories?
