Golbat is a large, blue bat-like Pokémon with purple wing membranes. It has small eyes with slit pupils and a massive mouth containing four fangs; females have smaller fangs than males. While its mouth seems to be otherwise empty, Golbat occasionally displays a long, purple tongue. Its pointed ears are tiny, and it has short legs with long, thin feet.
It feeds on the blood of both Pokémon and humans, and is capable of drinking over 10 ounces (300 mL) of blood in one sitting. Golbat drinks so much blood, that its blood type will change to that of its victim following a feed. It is also gluttonous, occasionally gorging itself to the extent that it becomes too heavy to fly. Golbat is nocturnal, and can be found quite easily in caves.
In Adventuring the Stone, Pikachu defeats a flock of Golbat so that he and the others can reach the legendary Stone of Adventure found deep within a cave.
Koga has a Golbat as one of his team members which first appeared in That Awful Arbok!. This Golbat is special in that it is able to use Supersonic in order to project a clear visual of the locations of others, using its gaping mouth as a screen. Agatha also possesses a Golbat, which fought against Koga's Golbat in Muk Raking in the Yellow arc. A flock of Golbat, Crobat and Zubat attack Misty, Erika and Brock at Tohjo Falls. Golbat later made a cameo appearance in the Ruby & Sapphire arc as wild Pokémon.
