Beast Kings

Beast Kings are special beings within their respective species who act as leaders and represent their species. It is not a racial distinction, but rather a concept of designation. They are born with the duty of protecting their species and fulfilling the desires of their subjects. 
Each species has its own king, and if the king dies, another beast from their species naturally succeeds them. The basic lifestyle of the Beast Kings is similar to that of their species, but they possess physical abilities far beyond ordinary beasts. They exhibit tremendous physical strength and speed and have been known to destroy entire buildings. 
Although they have a humanoid appearance akin to Beast-kin, their mentality is closer to that of animals. There is a significant disparity in strength between the Beast Kings depending on the type of the beast. For instance, in battles between the Cat King and the Dog King, the King of Dogs will win; if the Dog King and the Wolf King fight, the Wolf King will win.
It is interesting to note that only terrestrial beasts among the Beast Kings take on a human form. This is because Humans dominate Earth, and birds and marine animals do not assume human forms because Humans haven't conquered the sky and sea.
The beasts they control include not only their respective species but also Beastmen. Nabi considered the cat Beast-kin Eboni as one of her subjects.
There used to be a Human King because humans are also animals. However, it is said that his powers were stolen by the Five Monarchs and the First Saint leading to his complete disappearance. Whether he is dead or living in hiding remains unclear.
