Shadows of the North: The Role and Reign of Ai Da Gan in Kingdom: Ashin of the North

Released as a feature-length special episode of Netflix’s critically acclaimed zombie-thriller series Kingdom, Kingdom: Ashin of the North serves as a dark, pivotal cornerstone for the entire franchise. While the special fundamentally revolves around Ashin (played by Gianna Jun) and the tragic origin of the resurrection plant, it introduces a complex geopolitical chess match across the northern frontier.

At the center of this geopolitical tension stands Ai Da Gan (Aidagan), the formidable leader of the nomadic Pajeowi Jurchen tribe. Portrayed with chilling charisma by actor Koo Kyo-hwan, Ai Da Gan is much more than a standard cinematic villain—he is a catalyst for devastation, a victim of political manipulation, and a crucial piece in the machinery that unleashes hell upon Joseon.

Who is Ai Da Gan?

Ai Da Gan is introduced as the ambitious and fierce chieftain of the United Pajeowi Jurchen tribe. Operating along the volatile northern border of the Joseon Kingdom, his people are caught in a delicate balance of power, poverty, and shifting loyalties.

• Presence and Authority: Ai Da Gan commands absolute loyalty from his warriors. He possesses a commanding, intimidating physical presence that instantly sets an ominous tone whenever he appears on screen.
• Political Ambitions: Unlike smaller regional tribes that kowtow to Joseon authorities, Ai Da Gan and the Pajeowi are rising in strength. He eyes Joseon’s northern territories with growing ambition, seeking security, respect, and power for his displaced and struggling people.
• Strategic Mindset: He is not merely a brute warrior; he is a calculating leader who assesses the weaknesses of the Joseon military garrisons, making him a formidable adversary for the southern kingdom.

The Pawn and the Massacre

Ai Da Gan’s most significant impact on the narrative stems from how easily he is weaponized by Joseon military commander Min Chi-rok.

In an effort to keep the Pajeowi divided and under control, Min Chi-rok orchestrates a dangerous deception. When 15 Jurchen hunters cross into forbidden territory and die, Min Chi-rok covers up the incident and tricks Ai Da Gan into believing that the northern Seongjeoyain village (where Ashin’s family lives) is responsible for the slaughter.

Blinded by grief and manipulated into righteous fury, Ai Da Gan leads his Pajeowi warriors in a brutal, merciless raid. He orders the utter destruction of Ashin’s village. This single act of calculated political violence becomes the structural epicenter of the Kingdom universe: it destroys Ashin’s life, strips away her humanity, and sets her on a path of absolute vengeance that eventually dooms the entire kingdom.

Koo Kyo-hwan’s Masterclass Performance

A major reason Ai Da Gan leaves such a lasting impression despite his limited screen time is the performance of Koo Kyo-hwan. Known for his nuanced character work, Koo brings a chilling unpredictability to the chieftain.

Instead of playing Ai Da Gan as a one-dimensional tyrant, Koo infuses the character with a quiet intensity. Whether he is negotiating with Joseon officials or watching his camp with hawklike observation, his portrayal highlights a man who believes he is acting in defense of his people’s honor—unaware that he is merely a disposable pawn in a larger governmental conspiracy.

The Ultimate Reckoning

Ai Da Gan’s fate is as violent and definitive as his reign. After realizing he was duped and witnessing the horrors unleashed by a grieving, vengeful Ashin, his narrative arc reaches a brutal climax.

Ashin, having mastered the resurrection plant and orchestrated a meticulous, blood-soaked plot of retribution, confronts Ai Da Gan directly. In a swift and terrifying display of her lethal archery skills, Ashin kills Ai Da Gan with a precise arrow to the head, bringing a definitive end to the Pajeowi chieftain’s chapter.

Legacy in the Kingdom Universe

Ai Da Gan embodies the core theme of the Kingdom series: human cruelty breeds monsters far worse than the undead.

While the resurrection plant provides the physical mechanism for the zombie apocalypse, it is human ambition, political exploitation, and figures like Ai Da Gan—and the Joseon officials who manipulated him—that create the social decay allowing the plague to spread. Through his ambition, manipulation, and tragic downfall, Ai Da Gan remains one of the most compelling antagonists in modern Korean dark fantasy.
