According to Darius, Monolophosaurus is believed to be a solitary hunter. However, it is possible that this carnivorous dinosaur's behavior of hunting in packs could have been influenced by the presence of Scorpius rex, a hybrid that caused fear and disrupted the natural behavior of many dinosaurs. Alternatively, it is also plausible that the genetic makeup of the Monolophosaurus clone could have contributed to its pack hunting tendencies, which Darius may not have been aware of at the time.
