Fan (ファン Fan ) is a recurring enemy in the Gradius series.
Description[]
Fans are enemies introduced in the original Gradius, notable for being the first enemies to be encountered. They are also the most common enemies in the game, and become recurring enemies throughout the entire series. They are generally found in the short space section that appears at the beginning of most stages in the series, and usually attack in groups following a formation. They neither shoot back nor actively chase the player, and just limit themselves to follow their scripted trajectory and then leave the screen, hoping to have bumped into the player's ship along the way. If the player manages to destroy an entire formation, they will usually leave behind a Power Capsule. As such, since they often don't pose much of threat by themselves, they mainly serve as a mean for the player to power up before their enter the main section of a level.
Attack patterns[]
Fans fly in groups of five to nine, following beyond each other in a line trail. They appear high or low on the screen, and then will move one row closer to the Vic Viper, then continue off the screen. If the entire row of Fans are destroyed, the last one will leave a capsule.
