Well, in comics they either do the rather boring "iconic superhero standing" (the thing with the legs apart and fists clenched where the perspective is slighly from below, it's supposed to look heroic or something) or they have signature poses, like Spider-Man swinging or crouching or Wolverine's slashing motion, or they hold some sort of weapon. There are actually not that many that look really engaging, IMO.
