In Solo Leveling, the Monarchs stand as some of the most formidable figures within the narrative, representing an elite echelon of power that few can rival. Recognized as the main antagonists of the series, these ten beings (including both historical and contemporary Monarchs) pose significant threats to the Hunters and the world itself. Their strength far surpasses that of most characters, with even the weakest Monarchs showcasing capabilities that eclipse the mightiest Hunters.
The Monarchs serve as pivotal antagonists in the overarching plot, primarily responsible for the creation of Gates on Earth. As tensions escalate towards the finale, their invasion represents a bid to acquire sufficient strength to confront the Rulers, their immortal foes. The unfolding struggle would have likely concluded in their favor had it not been for the resilience and tenacity of characters like Sung Jinwoo and Ashborn.
10. Baran
The Monarch of White Flames and the King of Demons

As the first Monarch to be introduced, Baran plays a crucial role in the development of Sung Jinwoo’s journey. Initially, Jinwoo combats Baran while still in a relatively weaker state, relying heavily on Esil’s assistance. Although Jinwoo eventually prevails, it’s revealed that the Baran defeated was merely a replica; the true Baran had already met his end at Ashborn’s hands. This context positions Baran as potentially the weakest Monarch due to his demise, yet he remains one of the most potent adversaries encountered by Jinwoo, exemplifying the series’ thrilling clashes between power and growth.
9. Querehsha
The Monarch of Plagues and the Queen of Insects

Querehsha stands out as the only female Monarch among the ten. Known as the Queen of Insects, she emerges as a significant threat during the series’ climactic battles, targeting key Hunters who possess characteristics of the Rulers. Her ruthless partnership with other Monarchs like Sillad amplifies her dangerous persona. Notably, Querehsha has a compelling relationship with Beru, the former Ant King, adding depth to her character. Ironically, like her insect counterpart, Querehsha meets her end through Jinwoo’s Mutilation skill.
8. Rakan
The Monarch of Fangs and the King of Beasts

Rakan, the fierce Monarch of Fangs, is characterized as direct and devastating. Notably, he seeks to eliminate Jinwoo before Antares is fully revived. His impressive stature and formidable strength enable him to engage S-Class Hunters with apparent ease. Although Rakan’s aggressive tactics set him apart, his journey reflects a blend of confidence and vulnerability, particularly when he confronts Jinwoo, demonstrating a shift in power dynamics throughout the narrative.
7. Yogumunt
The Monarch of Transfiguration and the King of Demonic Specters

Adopting a more strategic role, Yogumunt serves primarily as a commander, orchestrating battlefield tactics rather than engaging directly. His partnership with Antares is crucial as he facilitates the movement of destructive forces. This approach highlights his intelligence despite an underlying arrogance. Jinwoo’s ultimate confrontation with Yogumunt emphasizes how far he has come in terms of strength, showcasing the latter’s relative weakness in isolation.
6. Sillad
The Monarch of Frost and the King of Snow Folk

Sillad emerges early in the series as an antagonistic force, embodying cruelty and arrogance. Known as the Monarch of Frost, he engages in intense conflicts and draws significant attention when he pushes Jinwoo to access the powers of the Shadow Monarch. Sillad’s character arc serves as an exploration of hubris in the face of an evolving threat, ultimately solidifying Jinwoo’s transformation into a formidable Hunter. The dramatic exchanges between Sillad and Jinwoo exemplify the narrative tension.
5. Tarnak
The Monarch of the Iron Body and the King of Monstrous Humanoids

As the Monarch of Iron Body, Tarnak is distinguished by his imposing presence, leading various monstrous humanoids across the dungeons.

His character exemplifies the struggle between raw power and strategic cooperation in combat, emphasizing how teamwork can overturn seemingly insurmountable odds.

The Monarch of the Beginning and the King of Giants

Captured by the Rulers, Legia’s essence is used to innovate Hunter abilities, signifying the narrative’s exploration of power dynamics. His role serves as a testimony to the strength and influence of Giants within the landscape of Solo Leveling.
3. Ashborn
The First Shadow Monarch and the King of the Dead

Ashborn, the inaugural Shadow Monarch, holds unparalleled strength among his peers. His backstory as the Greatest Fragment of Brilliant Light reveals his transformation from a Ruler turned Monarch. The narrative illustrates his compassionate choice to empower Jinwoo rather than using him as a pawn, contrasting the motivations of other Monarchs. His character ensures the readers appreciate the complexities that lie beneath the surface of power, loyalty, and sacrifice.
2. Antares
The Monarch of Destruction and the King of Dragons

Antares, a force of nature, culminates as one of the most formidable Monarchs within Solo Leveling. His sheer destructive potential is illustrated dramatically when he wreaks havoc across North America. Despite his overwhelming power, a cunning strategy from Jinwoo culminates in a decisive confrontation, showcasing the theme of cunning versus brute strength throughout the series. Antares exemplifies the ferocity of Monarchs, solidifying his place as a central figure.
