I was reborn as a tiger in the zoo, but was used as medicine by the keepers. At the critical moment of life and death, I activated the super evolution system. As long as I hunted, I could become stronger. After killing the breeders, I led the herd to a bloodbath in the park, but was named the Tiger King by a global live broadcast. Humanity regarded me as a disaster, but I discovered that the world was quietly mutating. In the frenzy of mutation, I devoured powerful enemies, conquered ethnic groups, and established an empire of mutated beasts. When the strongest mecha corps in mankind pressed against the territory, I stood on the top of the mountain and sneered. This wasteland needs a new king.
