The Indominus Rex of Jurassic World is a beast reviled for its infamous slaughter. In seeking to outdo their old rivals, Biosyn created another Indominus alongside their Giganotosaurus to reside within their Sanctuary. The existence of the Indominus Rex is kept under lock and key, and only spoken of in the darkest of corners for fear of public backlash. With the pair in shared territory, the Giganotosaurus attempts to court the Indominus. Courting, however, is difficult when three Tyrannosaurus are invading their home. Now the apex male, Zeb, must defend his home and prove himself worthy of being a potential mate to Anathema.
