The Frost Monarch was the King of Snow Folk and one of the nine Monarchs.
The Frost Monarch was a muscular old elf with blue skin, long silver hair with a single long strand dangling over the right side of his face, blank white eyes, and round ears. He wore a ragged white cloak with a black collar over a tattered white shirt, ragged black pants, and a pair of black boots.
The Frost Monarch was a cocky and collected individual who did not like to play the odds or get ahead of his own plans. He was also implied to have a distaste for unnecessary conflict, as displayed when he instantly knocked out the humans he encountered on Jeju Island with his powers instead of taking the time to massacre them. In the face of power vastly superior to his own, however, he tended to act panicked and even reckless, as displayed by how he impatiently urged the other Monarchs to help him kill the Shadow Monarch's vessel without realizing just how risky it was.
Several days after the Jeju Island S-Rank Gate was finally cleared, the Frost Monarch picked up traces of the Shadow Monarch's power on Jeju and traveled there to make sure. Along the way, he bumped into the Beast Monarch, who had picked up on Ashborn's trail as well, and the two of them agreed that it was about time to finish their war with the Rulers.
While he was out hunting for the Rulers in America, the Frost Monarch ran into Yogumunt and learned from him that one of the Rulers had been located in Korea. Before they could leave, however, they were ambushed by Il-Hwan, who attempted to kill them both to no avail.
At some point between his skirmish with Il-Hwan and the events of the Tokyo S-Rank Gate, the Frost Monarch tracked down Go Gunhee, one of the seven Rulers’ vessels, in Korea and killed him in his own office. But before he could head back to the chaos world, however, the Frost Monarch was suddenly attacked by Jinwoo, who had traveled back home using Shadow Exchange. Realizing that Jinwoo was Ashborn's human vessel and that he was in real danger, the Frost Monarch managed to force the human back with a large wall of ice and fired an ice spear at Gunhee, buying him enough time to create a portal and escape.
As the Shadow Monarch was only matched in strength by Antares, the Frost Monarch knew that they could easily lose the war with him as their enemy. As a result, he regrouped with the other Monarchs to decide their next move and asked them to help him kill Jinwoo before it was too late. Although the Iron Body Monarch and Yogumunt both refused out of fear, the Beast Monarch and Querehsha both agreed to help on the belief that Jinwoo had not yet obtained his full strength.
Several days later, once Jinwoo showed up to fight the Beast Monarch after the latter went on a rampage across Seoul, the Frost Monarch and Querehsha joined him and the three of them attacked Jinwoo all at once. Although Querehsha was killed during the course of the fight, the Frost Monarch was still able to keep Jinwoo distracted long enough for the Beast Monarch to fatally impale the latter from behind, seemingly winning them the battle.
However, just when it seemed like Jinwoo was truly dead, his black heart suddenly began to beat and he started to return to life. Realizing with a panic that the Shadow Monarch was descending, the two Monarchs attempted to finish Jinwoo off for good, but were thwarted by Il-Hwan, who sent them both flying into a nearby building with one well-placed kick. The Beast Monarch abandoned the fight soon afterwards upon realizing that they had failed, leaving the Frost Monarch all by himself.
Although he was now alone, the Frost Monarch refused to back down and summoned a huge ice storm, slicing off Il-Hwan's left arm in the process. Before he could kill Il-Hwan, however, he was thwarted by Jinwoo, who returned from the dead with his true powers. Still stubbornly refusing to back down even though he had no chance of winning, the Frost Monarch attempted to kill Jinwoo by throwing his trident at him and attacking him with his ice magic. However, this was to no avail, as Jinwoo effortlessly destroyed his trident with one hand and then slashed him across the chest, inflicting him with fatal wounds. Realizing that he had lost, the Frost Monarch only had time to scream in rage right before his vessel gave out and he died, causing his body to dissolve into shards of light and finally avenging Gunhee's death.
As a Monarch, the Frost Monarch was an immensely powerful individual.
- Immense Strength: The Frost Monarch possessed immense physical strength. He was able to fight evenly against Go Gunhee while still holding back and push Jinwoo to his limit with just brute force during their second battle.
- Immense Speed: The Frost Monarch possessed immense speed, as he was able to easily dodge Gunhee's attacks and move fast enough to pressure Jinwoo with his movements during their second battle.
- Ice Magic: The Frost Monarch was able to almost effortlessly create tremendous waves of ice, shape ice into weapons, create monsters out of ice, and even summon massive ice storms.
- Spiritual Body Manifestation
- Sleep Inducement: The Frost Monarch was able to put ordinary humans to sleep just by snapping his fingers.
