Tyrandreigon flies around, often beating its six wings fast enough to whip up sandstorms. While the central head focuses on attacking other Pokémon, the two heads at the ends of its arms seem to be just as interested in eating rocks and soil.

The heads on their arms do not have brains. A Tyrandreigon is so overwhelmingly powerful, it can bring down a whole mountain to make its nest.
