I have read in the survival guide that the typical Na'vi is probably 4 times stronger than the regular human. The page on this wiki about the Na'vi says that pound for pound, humans are probably stronger. Jake Sully's avatar body looked physically stronger than the bodies of the male Na'vi, so does that mean humans are physically stronger? Does gravity play a role in determining the level of strength? How much does a typical Na'vi weigh?
I personally believe that pound for pound, a human would be stronger than a Na'vi. The Na'vi body structure is more willowy and doesn't seem like it can support a lot of weight. The human body structure seems sturdier and more able to support weight. So what do you think?
