After a solar catastrophe transforms Pine Ridge into a city of red fog and mutant beasts, Rex, a tiger gifted with speech and evolving crystal powers, becomes humanity’s unlikely protector. To stop Atlas, a giant lizard created and controlled by Helios Corporation, Rex must unite humans and independent mutant kings, expose the experiments behind the disaster, and risk his own mind by absorbing three powerful cores. The final battle is not only for the city—but for Rex’s right to remain himself.
