Dracky

The Dracky, in Japanese, is a monster in the Bird Family. It first appears in Dragon Quest I.

Biology
The Dracky is a round, chubby bat-like monster with wide googly eyes and an even wider smile that hosts two large, sharp canine teeth. It is often encountered in the wild alongside the Slime or the She-Slime, being one of the first monsters you can encounter in the various games it is featured. It's a very well known monster, appearing in many main entries of the franchise, as well as in the majority of spin-offs, its popularity being not that far from the mascot of the franchise.

Its description in Dragon Quest VIII's Bestiary, reveals that the Dracky species originated in the World of Darkness, suggesting that they lived there before inhabiting both the World of Light and possibly Alefgard, which could explain why they are missing in that trilogy's third game, but appear in both Dragon Quest (videogame) and Dragon Quest II.

According to the Dragon Quest 25th Anniversary Encyclopedia of Monsters Illustration Book, the drackies are primarily nocturnal and can be found mostly inside caves, where light is scarce, and meadows at night, were they move around flapping its tiny wings to pursue their prey. Also, in Dragon Quest XI we can observe them sleeping hanging from the branches of trees during the day, to protect themselves from the rays of sunlight.
