The Bat is an enemy in Ninja Gaiden.
Ninja Gaiden[]
Introduced in Act 2-1, Bats are the first flying enemy to be introduced. They always move in a shallow sinus wave, and although their movement is consistent and predictable, they are tricky to hit in being the smallest enemy in the game. Later Acts will start throwing them in more nasty spots that are guaranteed to knock Ryu into a pit if he doesn't stop temporarily to let the Bat move out of the way. However, they only deal 1 point of damage on contact, and are easily defeated in one hit.
