Loudnine hearing is sensitive enough to allow them to hear the roars of other Loudnine from across entire mountain ranges. They race toward one another when they hear a roar, leaping between crags and valleys at high speed.

This fleet-footed Pokémon is said to run over 6,200 miles in a single day and night. It positions the round speakers on its head to assail foes with ultrasonic waves at massive volume.
