Bat

Bats, specifically Vampire Bats are a basic enemy seen in many games from the Castlevania series. Bats have appeared in every single Castlevania game except for Castlevania: Curse of Darkness.

Overview
As a lesser enemy, bat's usually hang down from ceilings until a hero comes near. Once close enough, they'll swoop down and fly at them.

Other bats will fly from off the side of the screen, and go in a relatively straight path, moving up and down slightly as they go. On a rare occasion, they will fly in from an open window.

Bats are not nearly as quick and don't maneuver up and down as much as Medusa Heads, but can be quite annoying when in numbers.

Types
Aside from appearing as common enemies, bats also come in much larger and more fiercer versions as boss enemies, such as:

...or as man/bat hybrids such as:
 * Bat Company (Castlevania: Dawn of Sorrow)
 * Darkwing Bat (Castlevania: Symphony of the Night)
 * Phantom Bat
 * Zapf Bat (Super Castlevania IV)
 * Razor Bat (Castlevania: Portrait of Ruin)


 * Creature Bat (Castlevania Legends)
 * Death Bat (Castlevania Adventure)

Simon's Quest
Two varieties of bats appear in this game. Those that live outdoors, and those that live in mansions. The outdoor variety moves steadily forwards, while the indoor variety flutter about in a circle, then rest a while, then move towards you again.

An unlimited amount of bats will flutter above you in each stage in the Simon's Quest Watch Game. They take a single hit to kill and worth 10 points. They will only attack you when you are in the air and it is possible to jump into them. They can only be attacked when jumping.

A larger variety of bat, called a Vampire Bat is also present in this game.
