I NEED MONSTERS

In preparation for chapter 8 (East of Eden), an introductory "podcast" (yep, I'm going to do it!), the and discussion on the woman who began as Cathy Ames, I need your input on MONSTERS.

Classic monsters, but not by category--vampires, werewolves, zombies, Inferno, etcetera--I mean specific, individual monsters with names.  These can be from movies, they can be from books, they can be from comic books, songs, folk tales, family, whatever.

There is one specific type of monster (though all monsters are needed!) I'm looking to focus on (the others I need for contrast's sake):

The TRICKSTER.  In Native American folklore, he's often called Coyote.  In European folklore and tales, he's often labeled Puck.  The problem I have with Puck--or pucks in general--is their general lack of deep malice.  The best example I can think of is Coyote himself, from Chabon's Summerland.  On the other end, there is Grendel, from Beowulf (from which a terribly awesome book, Grendel, was written by John Gardner).

The trickster is a liar.  A Father-of-all-Lies kind of character.  Who lies just to lie, or just to mess people up, or because it screws things up and that what he loves most.  Screwing things up. 

So, Folks, I need a LIST.  Monsters, people.  Movie fans, book fans, aficionados of horror:  Monsters.  Comment with the names of monsters.

And don't forget to sign up as follower and get your picture over there.  I'm doing a drawing soon.  That means free stuff, and as well all know:  FREE STUFF GOOD.
