Gomez appears exclusively in the second episode of the Sol Bianca series, where he is introduced as a cunning and ruthless space pirate captain. His primary goal in the story is to steal a valuable substance known as Pasha, which puts him in direct opposition to the crew of the Sol Bianca, who are after the same prize. This confrontation defines his role as the central antagonist of that episode.

His personality is characterized by his craftiness and a strong, vengeful streak. After losing the initial battle against the all-female pirate crew of the Sol Bianca, Gomez becomes obsessed with revenge. Rather than relying solely on direct force, his notable abilities include the use of unconventional and underhanded tactics. To retaliate against his rivals, he sabotages their ship by unleashing a swarm of machine-consuming worms, a clever and devastating attack intended to cripple their vessel. As a further act of sabotage, he also causes one of the crew members to fall gravely ill.

The narrative provides no details about his background, such as his origins, history, or how he became a pirate captain. Information on his key relationships is limited to his adversarial role against the protagonists; he is driven to swear revenge against them for their earlier victory. Similarly, the story does not depict any significant development or change in his character. His abilities are demonstrated through his strategic cunning and the use of technological sabotage, specifically the worm-based attack, rather than through any personal physical or combat prowess shown on screen.
