Woobat is a blue, spherical Pokémon, resembling a Honduran White Bat. It is covered in shaggy fur and has a large, piggish nose with a heart-shaped nostril. Tow tufts of shaggy fur hide its eyes, and its mouth has a single fang in the center of its upper jaw. There are two relatively small, black wings on either side of its body. Woobat's nose serves various purposes. It uses ultrasonic waves from its nostrils for echolocation. It can also be used to grip cave walls as Woobat sleeps. This leaves heart-shaped marks on the walls of caves.
Karl in the 13th movie wears a baseball cap with a Woobat depicted on it.
Woobat's evolutionary line seems to have a connection with Zubat's family. Both of them are Bat Pokémon species, live in caves or other dark places, and have no visible eyes; furthermore, both of them reach their respective fully-evolved form by friendship, and both have similar Shiny forms (with green main bodies). Also, Woobat and Zubat have somewhat similar English names, both having bat as a suffix.
Woobat is the only Pokémon with a base stat total of 313.
Woobat shares its species name with Zubat, Golbat, and Crobat. They are all known as the Bat Pokémon.
