Bombardero, a guilt-haunted operative within the Tarantula assassin syndicate, navigates a brutal existence thrust upon him through coercion. Despite his imposing, burly frame, he moves with lethal swiftness, deploying explosive mines with precision during missions—a tactic echoing methods seen in prior Lupin III episodes, though his story unfolds solely within *Island of Assassins*. Forced into Tarantula’s ranks, he aligns with defectors plotting liberation from the organization’s grip, their rebellion fueled by years of enforced bloodshed. Doc, a surgeon crafting an antidote to neutralize Tarantula’s poison, spearheads their desperate bid to escape the island and claim its hidden gold—a plan doomed by betrayal and sabotage.

In the uprising’s climax, Bombardero faces Gordeau, Tarantula’s leader, who mortally wounds him. Defiant to the end, he triggers an explosive vest in a final bid to kill Gordeau and shatter the cycle of violence, though the act proves futile. His death mirrors the unresolved trauma shared among Tarantula’s victims, including Ellen, whose brother suffered similarly under the syndicate. Bombardero’s arc concludes within the special’s confines, his story absent from later Lupin III narratives.
