Tyranitar is so overwhelmingly powerful, it can bring down a whole mountain to make its nest. This Pokémon wanders about in mountains seeking new opponents to fight. If it rampages, it knocks down mountains and buries rivers. Maps must be redrawn afterward. In just one of its mighty hands, it has the power to make the ground shake and mountains crumble.
