After another battle with Pokémon, you were exhausted, and naturally, you decided to rest. You were about to return to the city when you suddenly heard a loud roar! Heaps of different Pokémon fled in all directions. And then you saw Tyrantrum.

Seeing such an ancient Pokemon is a big achievement, of course! However, this Tyrantrum doesn't seem to be a friendly bunch, at least for now. "Raaggh!"
