Dr. Grace Augustine is a scientist stationed on Pandora inhabited by a humanoid species called the navi. She is in charge of a program which places human 'pilots' in control of Avatars, which are artificially grown bodies generated with both navi and human DNA. She tries to seek wealthness in Pandora from plant instead of mineral (unobtanium) which can be located at the bottom of hometree and she likes plant more than human.
