Mick Scoresby was no stranger to big game hunting, though the practice of hunting ocean game had long passed on Earth by the time he arrived on Pandora. With the discovery of amrita, Scoresby was hired to hunt tulkun. He quickly developed efficient methods to do so and became one of the most important people in the RDA’s Cet-Ops division.

Armed with a top-of-the-line fleet of hunting vessels personally provided by General Ardmore, Scoresby took tulkun hunting to the next level. Designing new tools, like the neutralizing AHD-9 Sound Cannon adapted from crowd control resonators on Earth, meant more efficient methods, more tulkun harvested, and more amrita for RDA benefactors.

When Jake Sully fled to the reef, Scoresby’s SeaDragon was conscripted by Quaritch to track him down. Though ultimately able to draw out the Sullys among the Metkayina by blatantly hunting tulkun in Metkayina waters, reckoning came for Scoresby’s SeaDragon in the form of an outcast tulkun bull: Payakan.

At the opening of the Battle at the Three Brothers Rocks, Payakan attacked Scoresby’s SeaDragon, throwing the vessel and its support fleet into chaos. In the following conflict, Scoresby was confronted by Payakan directly. This encounter cost Scoresby an arm, a crew, and a fleet, but only served to further drive his ambition to hunt as many tulkun as possible in the wake of his defeat at the Three Brothers Rocks.

Down a crew, Scoresby’s operation began to fall behind on their quota. A timely opportunity presented itself when RDA reconnaissance revealed a large aggregation of tulkun pods gathering at the Metkayina Spirit Tree for the Calf Communion ceremony. Scoresby pitched a bold plan to infiltrate the ceremony and gather more than a year’s worth of amrita in a single hunting operation.

What would have been Scoresby’s crowning achievement as a hunter quickly turned to failure, however, as the tulkun defied expectation, rising to their own defense. The turning tide of the battle resulted in Scoresby’s death at the jaw of Ta’nok, another tulkun his hunting operations had blinded and left for dead.
