Dr. Grace Augustine is a scientist stationed on Pandora inhabited by a humanoid species called the Na'vi. She is in charge of a program which places human 'pilots' in control of Avatars, which are artifically grown bodies generated with both navi and human DNA. She studies the plants and creatures of Pandora instead of using mineral (unobtanium) for wealth, which can be located at the bottom of Hometree and she likes plant more than human.
