The Succession Contest arc in Hunter x Hunter introduced a massive number of new characters, factions, and power systems, but very few made an impression as quickly as Hinrigh Biganduffno. As the underboss of the Xi-Yu Mafia Family, Hinrigh initially appears to be another underworld figure caught in the chaos aboard the Black Whale. However, the deeper the arc progresses, the clearer it becomes that he is one of the smartest, most competent, and most strategically dangerous individuals introduced in the series.
Hinrigh stands out because he combines mafia authority, tactical intelligence, and a highly creative Nen ability. Unlike many characters in Hunter x Hunter who rely purely on overwhelming strength, Hinrigh approaches conflict through planning, observation, and adaptability. His actions during the mafia war aboard the Black Whale also place him directly in the middle of the conflict involving the Phantom Troupe, Morena Prudo, and Hisoka.
Understanding Hinrigh is essential for understanding the current direction of the manga. Let’s break down his role in the Xi-Yu Mafia, his Nen powers, and why he has become one of the most important characters in the Succession Contest arc.
Who is Hinrigh in Hunter x Hunter?
Hinrigh Biganduffno is the underboss of the Xi-Yu Family, one of the three major mafia organizations operating within the Kakin Empire. During the Succession Contest arc, the Xi-Yu Family becomes deeply involved in the chaos aboard the Black Whale, the massive ship transporting citizens and royalty toward the Dark Continent. Hinrigh acts as one of the organization’s main field operatives and strategists throughout the conflict.
As underboss, Hinrigh holds authority second only to Xi-Yu leader Onior Longbao. He oversees operations across several ship tiers and directly handles sensitive missions involving rival mafia groups and dangerous Nen users. His position also gives him access to restricted areas aboard the Black Whale, making him one of the most influential underworld figures in the arc.
What immediately separates Hinrigh from many mafia characters is his personality. He remains calm, analytical, and observant even in highly dangerous situations. Instead of acting impulsively, he constantly studies opponents, predicts behavior, and adjusts strategies accordingly. This intelligence makes him far more dangerous than his relaxed demeanor initially suggests.
The Xi-Yu Mafia Family Explained
The Xi-Yu Family is one of the three dominant mafia factions within the Kakin Empire, alongside the Heil-Ly and Cha-R families. Among these groups, the Xi-Yu are considered the strongest in terms of finances, manpower, and influence. They control major operations aboard the Black Whale and maintain direct ties to Kakin royalty.
The family is led by Onior Longbao, who serves as a high-ranking figure connected to the royal family itself. Their benefactor is Third Prince Zhang Lei Hui Guo Rou, which gives the Xi-Yu political protection and additional influence during the Succession Contest.
Unlike the Heil-Ly Family, which embraces chaos and mass murder under Morena Prudo, the Xi-Yu operate more traditionally. Their goal is to maintain order, territory, and business stability while preventing uncontrolled conflict from destabilizing the ship entirely.
Hinrigh becomes especially important because he acts as Xi-Yu’s main problem-solver during the growing mafia war. He investigates murders, tracks enemy movements, negotiates with dangerous factions, and handles direct combat when necessary. This makes him one of the arc’s central operational leaders.
Hinrigh’s Nen Ability Explained
Hinrigh’s Nen ability is called Biohazard, and it is one of the most creative abilities introduced in the Succession Contest arc. As a Conjurer, Hinrigh can transform objects into living creatures while retaining aspects of the original object’s functionality.
For example, Hinrigh can turn handcuffs into pigeons, knives into snakes, or tracking devices into oysters. These transformed creatures can still partially retain the function of the original object, making the ability incredibly versatile during combat and surveillance operations.
What makes Biohazard so dangerous is its flexibility. Hinrigh can use it offensively, defensively, or strategically, depending on the situation. He creates living traps, spies on enemies, restrains opponents unexpectedly, and manipulates environments creatively. The ability reflects Hunter x Hunter’s core Nen philosophy, where intelligence and adaptability matter more than raw destructive power.
The ability also reveals Hinrigh’s mindset as a fighter. Rather than overpowering enemies directly, he prefers controlling situations and exploiting openings. This approach f
its perfectly within the strategic tone of the Succession Contest arc.
Why Hinrigh’s Ability Is So Effective
Biohazard works especially well because Hinrigh understands exactly how to maximize its potential. Many Nen users in Hunter x Hunter have strong abilities, but few use them with the same level of efficiency and creativity.
During battles against Heil-Ly members, Hinrigh constantly uses environmental manipulation to gain advantages. He transforms ordinary objects into hidden weapons or surveillance tools, forcing enemies into situations they cannot predict. His ability also works well in crowded environments like the Black Whale, where subtlety matters more than brute force.
One of the best examples comes during his confrontation with Heil-Ly member Padaille. Hinrigh uses transformed handcuffs disguised as pigeons to restrain and disorient his opponent before turning the enemy’s own weapon against him. The fight demonstrates how dangerous tactical Nen users can become in Hunter x Hunter.
His ability also reflects Togashi’s writing style. Rather than focusing purely on spectacle, battles involving Hinrigh emphasize strategy, timing, and psychological control. This makes his scenes feel tense and unpredictable even without massive explosions or overwhelming power scaling.
Hinrigh’s Role in the Mafia War
The Succession Contest arc gradually evolves into a large-scale mafia conflict between the Xi-Yu, Heil-Ly, and Cha-R families. Hinrigh becomes one of the central figures trying to manage this escalating situation aboard the Black Whale.
After numerous murders linked to the Heil-Ly Family begin spreading across the ship, Hinrigh investigates the killings personally. He quickly realizes that Morena Prudo’s group is behaving differently from traditional mafia organizations. Instead of focusing on profit or territory, the Heil-Ly seem driven by pure destruction and chaos. This realization changes the entire tone of the conflict.
Hinrigh understands that standard mafia rules no longer apply because Morena’s followers actively seek mass violence to level up their Nen abilities. As a result, he shifts from normal underworld operations into full tactical warfare. His leadership becomes critical during this stage. He coordinates with allies, tracks enemy movement, and works alongside both Xi-Yu and Cha-R operatives to contain the growing threat. Without Hinrigh, the lower tiers of the Black Whale would likely descend into even greater chaos.
Hinrigh and the Phantom Troupe Connection
One of the most interesting parts of Hinrigh’s storyline is his interaction with the Phantom Troupe. Initially, the mafia families fear the Troupe’s presence aboard the Black Whale because of their violent reputation and connection to Hisoka. However, Hinrigh quickly realizes the situation is more complicated.
The Phantom Troupe is not directly responsible for the killings spreading across the ship. Instead, the real source of instability is Morena Prudo and the Heil-Ly Family. Hinrigh therefore begins cooperating with the Troupe temporarily because both sides share the same immediate enemy. This alliance creates fascinating tension.
Hinrigh knows the Troupe cannot truly be trusted long-term, but he also recognizes their usefulness in eliminating Heil-Ly members. His willingness to cooperate pragmatically with dangerous criminals highlights how practical and intelligent he is compared to more emotional characters.
His scenes with Nobunaga especially stand out because both characters respect competence and tactical thinking. Their interactions feel less like traditional hero-villain dynamics and more like experienced professionals temporarily aligned by circumstance.
Why Fans Like Hinrigh So Much
Hinrigh became surprisingly popular among Hunter x Hunter fans despite being introduced relatively late in the series. One major reason is how naturally he fits into the story’s strategic style.
Unlike many side characters who exist mainly to support stronger figures, Hinrigh feels fully capable and independent. He solves problems actively, makes intelligent deductions, and contributes meaningfully to the arc’s progression. Fans also appreciate that he remains calm under pressure without feeling emotionally detached.
His Nen ability also gained attention quickly. Biohazard perfectly represents the creativity fans love about Nen combat. Rather than relying on simple power escalation, Hinrigh uses intelligence and environmental manipulation to stay dangerous. Many readers consider him one of the best new characters introduced during the Succession Contest arc.
Another factor is his balance between professionalism and unpredictability. Although Hinrigh usually behaves rationally, he occasionally shows a darker and more ruthless side. This complexity prevents him from feeling one-dimensional and makes his decisions harder to predict.
How Hinrigh Reflects the Tone of the Succession Contest Arc
The Succession Contest arc is far more political and strategic than earlier Hunter x Hunter storylines. Instead of focusing mainly on tournament battles or adventure, the arc emphasizes information warfare, hidden alliances, and psychological conflict.
Hinrigh embodies this tone perfectly. He succeeds not because he is overwhelmingly powerful but because he understands systems, people, and strategy. His role reflects how the current arc rewards intelligence and adaptability more than straightforward combat ability.
The mafia storyline itself also expands the world-building significantly. Through characters like Hinrigh, Togashi explores how criminal organizations function within the Kakin Empire and how they intersect with the royal succession war. This adds another layer of complexity to an already dense narrative. Hinrigh’s presence, therefore, helps connect multiple storylines together naturally.
Hinrigh vs Morena Prudo’s Chaos
Hinrigh and Morena effectively represent opposite philosophies during the mafia conflict. Hinrigh values control, structure, and calculated operations. Even though he works within organized crime, he still operates according to logic and long-term planning. Morena, meanwhile, embraces total chaos and destruction for its own sake.
This contrast creates one of the arc’s most interesting thematic conflicts. Morena’s followers grow stronger through indiscriminate killing and destabilization, while Hinrigh attempts to contain violence strategically. Their conflict therefore becomes larger than simple territory disputes. It represents two completely different approaches to power and survival aboard the Black Whale.
Hinrigh’s determination to stop Morena also reveals his sense of responsibility. Despite being a mafia underboss, he recognizes the danger her ideology poses to everyone aboard the ship. This moral complexity makes him feel more nuanced than a typical crime syndicate character.
Why Hinrigh Could Become Even More Important
As the Succession Contest arc continues, Hinrigh’s role appears increasingly significant. He is directly connected to several major plotlines involving Hisoka, the Phantom Troupe, Morena, and the Kakin underworld.
Because of his intelligence and adaptability, many fans believe he may survive much longer than expected in an arc known for unpredictable deaths. His ability to gather information and build temporary alliances makes him uniquely valuable within the current narrative structure. He also represents a different type of strength within Hunter x Hunter.
Characters like Gon or Uvogin rely heavily on overwhelming force, while Hinrigh demonstrates how dangerous strategic thinking can become when paired with versatile Nen abilities. This aligns closely with the series’ long-standing emphasis on creativity over raw power. Even among the massive cast of the Succession Contest arc, Hinrigh continues standing out consistently.
Hinrigh Biganduffno quickly became one of the most compelling characters introduced in the Succession Contest arc because he perfectly captures what makes Hunter x Hunter unique. He combines strategic intelligence, creative Nen usage, and underworld influence in a way that feels deeply connected to the arc’s political and psychological themes.
As the underboss of the Xi-Yu Family, Hinrigh plays a critical role in managing the growing mafia war aboard the Black Whale. His Nen ability, Biohazard, allows him to control situations creatively rather than relying on brute strength alone. More importantly, his calm and analytical personality makes him one of the few characters capable of steering the arc’s increasingly chaotic environment.
Whether interacting with the Phantom Troupe, investigating Morena’s massacres, or manipulating battlefield conditions through Nen, Hinrigh consistently proves himself as one of the smartest players in the current storyline.
That combination of intelligence, adaptability, and tactical creativity is exactly why Hinrigh has become such an important figure in Hunter x Hunter’s modern era.
Another reason Hinrigh stands out is how well he adapts to uncertainty, which is one of the defining elements of the Succession Contest arc. Unlike characters who rely on fixed plans, Hinrigh constantly updates his strategies based on new information, enemy behavior, and shifting alliances.
This flexibility allows him to stay one step ahead in situations where even small miscalculations can lead to death. It also reflects a deeper understanding of Nen combat, where creativity and timing often matter more than raw strength. As the conflict aboard the Black Whale becomes more unpredictable, Hinrigh’s ability to think and react dynamically may ultimately determine his survival.
