Belmie watch their surroundings carefully with their singular, large red eye. When their back part rotates, they generate a faint magnetic field that often causes them to stick to each other if they get too close.

People in ancient times imagined that Belmie were transformed from the reflections of stars that twinkled on gentle waves at night. When Belmie gather in a swarm, they move in perfect unison as if they were but one Pokémon.
