Seth Rich Carter orchestrates the Trans-America Wild Race as an official representative of Great Motors (GM), balancing dual roles as technical director and vice president of public relations. Formerly a GM engineer, he poured extensive effort into engine innovation, only to face superiors' criticism and threats of dismissal over policy conflicts. Driven by the prospect of ascending to GM’s CEO, Seth relentlessly pursues Dylan G. Oldin’s victory in the race, maintaining a facade of composed professionalism to cloak his ambitions. At a pre-race gala, his polished demeanor cracks when confronting Appare Sorano and Kosame Isshiki over their unorthodox appearance, demanding their expulsion from the event.

Seth sports cropped blonde hair and piercing green eyes, his maroon three-piece suit accented by an orange waistcoat, emerald tie, and coordinating pocket square. Having shifted from engineering to corporate strategy, he firmly rejects any return to technical work, focusing solely on climbing GM’s executive ladder.
