Chang Changku, designated Cyborg 006, began his life as a celebrated Chinese chef and restaurateur, operating a thriving farm that supplied fresh ingredients for his culinary creations. His world shattered during a disastrous fire-breathing performance that ignited his restaurant, triggering a chain of calamities—the loss of his home, spouse, and livelihood. Consumed by grief, he sought death by hanging but was captured mid-attempt by Black Ghost operatives. They rebuilt him as a cybernetic soldier, grafting enhancements that included a flame-spewing mechanism capable of projecting 3,000°F fire. This modification allowed him to melt through subterranean rock, obliterate enemy defenses, and execute precision cooking techniques, merging combat utility with culinary artistry.

Freed from Black Ghost’s control, he channeled his trauma into nurturing allies as a team cook, using hearty meals and unflagging humor to bolster morale during missions. Alternate histories depict his pre-cyborg existence as an impoverished farmer ravaged by livestock plagues and crushing taxes, driving him to the same fatal brink before his cybernetic rebirth. Regardless of origin, his postwar life consistently led him to Tokyo, where he opened a restaurant, blending combat-honed discipline with gastronomic passion.

Though his demeanor radiates levity and optimism—often serving as his team’s emotional bedrock—his cheerfulness subtly underscores a resilience tempered by loss. Despite mechanical augmentations, he steadfastly identifies as a chef, wielding woks and flames with equal mastery, his culinary ethos inseparable from his identity as both warrior and survivor.
