A substance that can be melted down into liquid and used as a fuel, weaponized, or used for more than any resource on earth.

Once humans found the unobtainium on Pandora, people living in Pandora neighborhoods started selling their houses cheap. Blue people called humans speciesist/human racist in the later additions/sequels to avatar when a planet wide war broke out at the same time as a planet wide famine, plaque, and natural disasters on Pandora. Humans started asking other humans for donations to support their organizations for saving Pandorian food, children, elderly persecuted, and animal life. There was also cheap Pandorian real estate available for humans who wanted to own property in another planet.
