Zubat is a small, blue bat-like Pokémon. It has two long, skinny legs. Zubat's face lacks any eyes and a nose. The insides of Zubat's ears and undersides of its wings are purple. Zubat's wings are supported by elongated 'fingers', and four teeth can be discerned from inside its mouth, two on the lower jaw and two on the upper.
A female has smaller fangs.
Though blind, they get around well with echolocation. They can also confuse foes with their high-pitched squeals.
Zubat is mostly nocturnal, forming colonies in perpetually dark places and hanging upside-down when asleep. When they awake, Zubat will constantly swarm around caves during the nighttime. Zubat avoids sunlight and bright places because prolonged exposure to the sun causes its body to become slightly burned, and otherwise causing it to become unhealthy.
Since Zubat prefer the dark, their primary habitat is caves, although during the daytime Zubat may also stay under the eaves of old buildings or in forests. However, at night, they can be found roaming outside, usually for food.
At night it goes in search of other Pokémon and sometimes humans to suck blood from, although the information is not documented as clearly as that of its evolution, Golbat.
This Pokémon was unavailable prior to Generation I.
