The Antigravity Unit also known as the Antigravity Device (反重力装置), is an enemy machine boss character from the original coin-op and all its ports.
The Antigravity Device was created by Grand Master Meio in order to achieve total control of gravity in a specified area or system, and serves as a sort of antigravity engine for the Flying Battleship Balrog. Its core computer is sentient and moves around within the system, capturing any enemy that comes close to its gravity pull, and then throws them violently against a wall.
