6. An Ent (Or Walking Tree)
Like Old Man Willow, or Treebeard, the Ent, herder of trees, it would be great to encounter a character of this sort - they add such gravitas to the story. In a world gone mad, where evil is bent on destroying all living creatures who are not in line with their purpose - sound familiar? - nature fights back against the atrocities. In our modern world, we have natural disasters, earthquakes, hurricanes and typhoons - I love the concept of nature itself deliberately taking a stand and righting the wrongs of mankind. I picture the trees more substantial than the ones in the Lord of the Rings, but still... I wouldn't mind an odd, interfering or helpful tree or Ent somewhere in the Desolation of Smaug.
