The action-packed manhwa series, Solo Leveling, is filled with powerful characters in different categories, ranging from Hunters and Monsters to Monarchs and Rulers. Out of these four categories, the Monarchs and the Rulers stand out as the strongest groups with their immense abilities and immeasurable power. However, that doesn't mean the Hunters are weak; they are extremely powerful humans, some strong enough to 'solo' dangerous S-Rank dungeons with little to no assistance.
