Gulf is a high-ranking Gothamite military leader, serving as Governor-general of Earth for the alien civilization Godom/Gotham. As one of Gotham's high generals, he played a decisive role in Earth's initial invasion. When surveillance detected Earth's political and scientific leaders convening at research center N1 to address the alien threat, Gulf authorized and executed a preemptive strike. This attack successfully eliminated the human leadership concentration, destroyed research centers N2 through N8, and devastated much of Earth's civilization, establishing the Gothamite occupation. Gulf's command position placed him among the highest-ranking leaders overseeing terraforming operations and military campaigns against human resistance, though his specific responsibilities relative to other Gothamite leaders like Col. Jrgens (Lupus) or Hegeler remain undefined. Throughout the conflict, Gulf remained primarily in a strategic command role within the Gothamite hierarchy.
