Gipsy Doc serves as the primary antagonist and the leader of the Pirate Guild in Cobra The Animation: The Psychogun. This organization is presented as a powerful and chaotic force within the galaxy, and Gipsy Doc commands it with a ruthless determination. His central role in the story is defined by his obsessive pursuit of a brilliant scientist named Utopia More. The motivation driving his actions is the acquisition of her groundbreaking discovery, an ancient record that is said to hold the key to unlocking the secrets of the universe. Gipsy Doc believes that by seizing this knowledge, he will gain the power to rule the universe, making universal domination his ultimate goal.

His single-minded quest places him in direct opposition to the series' protagonist, the space pirate Cobra.

In his efforts to defeat Cobra and secure the ancient record, Gipsy Doc forms a key alliance with Crystal Boy, who is identified as Cobra's revived arch-nemesis. By joining forces with this character, Gipsy Doc strengthens his position and increases the threat level against the protagonist. His development within the story is tied directly to this escalating conflict, as he coordinates the Pirate Guild's operations and leverages his partnership with Crystal Boy to overcome the legendary space pirate and claim the universe-altering power he seeks. Beyond his role as the commanding leader of the Pirate Guild and the mastermind behind the plot to capture Utopia More, no detailed information on his specific abilities, personal background, or further character development is available.
