Lucchi is a Gorgosaurus minion serving Golgo, known as the "white devil." He operates alongside fellow minion Gocchi. Lucchi takes part in an ambush targeting the Pteranodon Punon with the intent to consume her, but the attack is thwarted by the arrival of the Tyrannosaurus Tyrano. Recognizing Tyrano as a powerful threat, Lucchi and Gocchi beat an immediate retreat. Later, they report to Golgo about rumors of "heaven," a paradise teeming with herbivorous dinosaurs ripe for hunting. Golgo commands them to find this place. Throughout the story, Lucchi and Gocchi function as subordinate antagonists relentlessly pursuing "heaven" under Golgo's orders. Their interactions display a comedic rapport, featuring improvised exchanges during their quest. Lucchi's role remains firmly fixed on advancing Golgo's objectives, with no significant individual development or expanded backstory beyond his function within the core conflict.
