Undeads, From WoW.
All i need to say!
Hahah, as for my favorite. Human all the way! Even though they arent myth!
But if i was to choose myth.
Are we talking about game critters, or anything? And keep in mind critters vary from game to game, movie to movie book to book.
Ogres in some games are Huge pale creatures, while in another game they can be tall and green. Or how about the orcs in WoW, and the orcs in LOTR.
Ok anyway, this one is from a movie. Have you ever seen The mummy returns? Yeah well anyway, Remember the army of Anubis, those dog things that wear a sphinx hat on there head, and carry those double sided halberd axe things! Yeah them, they are cooool! :P
EDIT: Added a link to what they look like, not a very good picture though.
