The Battle Flappers, like the Flappers, look similar to the Egg Pawn, possessing a round torso, black undercarriage, and dome-shaped head that the Egg Pawns have. However, Battle Flappers have bat-like wings instead of arms, and two turbines on their backs. Additionally, while they have the Egg Pawns' pointy nose and panel-based mouth, they have black sunglasses instead of eyes. In terms of color scheme, the Battle Flappers are purple with yellow and light purple details.
The Battle Flappers made their first appearance in Sonic Rush as an enemy. In this game, they only appear in Night Carnival.
In gameplay, Battle Flappers are stationary or patrol their local area, but when they detect the playable character, they fly towards them. Battle Flappers possess no form of attack, but they can damage a careless player in case they run into one. Other than that, they are easily destroyed with either the Spin Jump/Axel Jump or the Super Boost/Fire Boost. Also, upon their destruction, they release an Animal.
