John Mercer is the main antagonist of Avatar: Frontiers of Pandora, along with his assistant Colonel Angela Harding. Mercer was a leader of the Resources Development Administration, being the Executive Vice President of Frontier Operations in the Western Frontier, with orders to gather materials and resources for RDA projects across Pandora for the Colonization of the Western Frontier. He was also the administrator of The Ambassador Program (TAP) over a decade ago. Mercer was a shrewd and ambitious businessman who saw the potential of Pandora and aimed to use it to his advantage. He had created The Ambassador Program together with his co-worker Alma Cortez. The program was meant to create raise young Na'vi and create diplomats for the RDA. Though Cortez wished for the program to do good, Mercer aimed to use it win the admiration of the organization. In 2138, Mercer along with Angela Harding and Alma Cortez kidnapped a group of Na'vi children from the Sarentu clan to use them for TAP. The kidnapping resulted in the decimation of the Sarentu, a deed which Mercer and Harding hid from the RDA by fabricating reports and destroying the bodies with corrosive acid which inadvertently created a toxic mist. Although Alma Cortez was on the fence about what had been done and had great guilt, Mercer manipulated and convinced her that the Na'vi were primitive and that abducting their children was a necessary evil for the greater good. He claimed to Cortez that the Na'vi were primitive savages, although it is unclear if he genuinely believed this, or if he knew they were more peaceful and complex than his claims were and used it to manipulate her. During TAP, he was known to have strict and rather cruel personality. For example, he physically beat Teylan for his bed wetting so badly to the degree he had bruises for weeks. He viewed Aha'ri's songcord as a useless piece of string, and when she touched him and broke the rule of no physical contact, he punished the entire group instead of only her. He also murdered Aha'ri when she tried to leave with her friends. When it was time to update Aha'ri's student profile, he merely vaguely wrote that she died to an unfortunate incident. When human-Na'vi relations soured throughout the 2140s, he changed the program to teach the Na'vi human combat methods and turn them against their own kind, making do with military assets instead.
