While greater in size than most large predators, the Giganotosaurus is sometimes less dangerous when encountered in the wild, due to its sluggish speed. Even still, getting trapped or chased down by a Giganotosaurus often means certain death for nearly any creature.
Taming a Giganotosaurus is a dangerous prospect. Its rage reaction, even when tamed, can sometimes cause it to briefly turn on members of its own tribe. Indeed it may even throw off its rider if it has been sufficiently angered! And yet, the sheer size and immense power that the Giganotosaurus possesses means that some factions endeavor to tame it as a fear-inducing "capital" beast of war -- even at great risk!
Fighting a Giganotosaurus directly is always a bad idea, as its rage rapidly grows with every hit it takes. With this rage, it builds increasing reserves of energy to use, making its iron-jawed bites progressively more deadly and enhancing its stamina.
