In an age of genetic collapse, scientist Li Ang is implanted with the genes of a praying mantis and a deep-sea fish, transforming into a half-human, half-beast known as "Mantis." To reverse his mutation, he hunts his own kind and collects genetic fragments. Every battle brings him closer to the abyss, and every kill lets his instincts consume him.
When the glow of a predator lights up along his back, he must find proof that he is still human before he becomes a monster.
