TV Special
Description
Goemon Ishikawa XIII, the thirteenth-generation heir to the legendary bandit Ishikawa Goemon, upholds his lineage as a master swordsman and occasional thief. His initial dynamic with Lupin III was adversarial in the original manga, targeting Lupin for attempting to steal his clan's secret alchemic formula for unbreakable swords. Repeated failures to defeat Lupin shifted his allegiance, recognizing Lupin as a valuable mentor. Lupin's assistance in avenging his uncle's death cemented their bond, enabling Goemon's public and brutal retaliation against the killer.

Anime origins vary. One version depicts him manipulated into opposing Lupin by the assassin Momochi, leading to a temporary alliance after outwitting their common foe. The TV special "Episode 0: First Contact" presents their first encounter during Goemon's quest for the legendary sword Zantetsuken; Lupin, Jigen, and Fujiko initially acted as adversaries before circumstances forced collaboration. The canonicity of this account is ambiguous.

Physically, Goemon adheres to traditional Japanese attire, typically a kimono and hakama, with variations in color and design across series. His long, unevenly cut hair reflects a rejection of modern grooming. His facial features often resemble Lupin's, enabling effortless impersonation. Design elements evolved, including a cleft chin in Part III and more youthful or masculine structures later.

His personality centers on intense cultural traditionalism and profound pride in his swordsmanship. He strictly follows Japanese customs, favoring konnyaku (notably impervious to his sword), enka music, meditation, fishing, and noh theater. He experiences deep shame when his abilities falter, such as Zantetsuken breaking or failing a task, often retreating for solitary training or deep meditation, a state rendering him nearly immovable even under threat.

Notable weaknesses include naivety around seemingly innocent women, whom he readily trusts despite frequent betrayals, and acute discomfort with overtly seductive women, causing him to freeze or flee. He is highly susceptible to bribes involving Japanese food and fiercely protective of children, often disregarding logic to aid them. Financial ineptitude leads him to fund scams or cults, losing money rapidly. While generally averse to modern technology, struggling with smartphones, cars, or cameras, he occasionally adapts, excelling at games like Xevious.

As a martial artist, he masters Kenjutsu, Iaido, Jujutsu, Karate, and Aikido, enabling feats like cutting bullets mid-flight, dismantling vehicles or structures, and defeating multiple attackers barehanded. His primary weapon, Zantetsuken, slices virtually any material except konnyaku jelly. Despite its lethality, he prefers non-lethal tactics, disarming opponents by destroying their weapons or clothing. Afterward, he frequently remarks, "I have cut yet another worthless object," referencing the samurai tradition that a katana must draw blood before sheathing—a rule he often bypasses.

His dynamic with the Lupin gang evolved from transactional cooperation to genuine, albeit conflicted, loyalty. He frequently challenges Lupin's methods, particularly womanizing or morally questionable heists, once vowing to deliver Lupin's killing blow as their final act. Despite this, he consistently aids Lupin in just causes, with interpretations suggesting admiration for Lupin's thieving prowess echoes his ancestor's legacy. His bond with Jigen is marked by mutual respect as fellow warriors, often pairing on missions. Though distrustful of Fujiko due to her betrayals, he collaborates when goals align.

Key relationships outside the gang include Kikyo, a childhood friend turned adversary who betrayed him during a dragon figurine mission, and Sadachiyo, a rival clan assassin defeated in a duel. He also nearly married Murasaki Suminawa in *The Fuma Conspiracy* but withdrew, deeming himself unworthy.

Character development highlights internal conflicts. In *Goemon's Blood Spray*, his pride shattered after failing to protect a yakuza boss, driving relentless training for redemption. Part V explored his role within the gang, questioning whether he was Lupin's friend or mere tool, culminating in a duel where victory brought regret rather than satisfaction. These arcs underscore his struggle to reconcile his rigid code with modern thievery and alliances.
