Beru

Beru, known as the Ant King in 'Solo Leveling', is an immensely powerful magical beast who serves as a soldier for Sung Jinwoo. Despite initially appearing to show mercy during the Jeju Island incident, his true nature is revealed to be one of cruelty and vengeance, restrained only by his loyalty to Jinwoo, creating a complex dynamic that challenges the protagonist's leadership in the upcoming second season.
