Air Rider

Air Riders are ninja-looking alien creatures who ride on different Air Ride Machines. The Air Ride Machines they ride on are said to be the same Air Ride Machines that Nightmare stole from all over the universe - most notably from the Star Warriors that were all but outnumbered by his monster forces. Air Riders are also shown to be able to wield different weapons, and can even be stored inside Destrayers. The Air Riders guard Nightmare's Fortress.

Four of the Air Riders even attacked Kirby in the dream sent to him and Tiff by Kabu, where Kirby utilized four anime-exclusive abilities (one of which would later make it into the games) and learned how to fly not just Warp Stars, but other battle vehicles, most namely the Air Ride Machines, as well.

Physical Appearance
Air Riders are small, gray, ninja-esque alien creatures with blue visors, dark blue-purple feet, and white gloves. They are shown to be able to carry batons, flamethrowers and missile launchers, gold maces, and endless supplies of green tops. The Air Riders are also shown to ride on different Air Ride Machines. The machines they have been shown to ride on are Formula Stars, Rocket Stars, Winged Stars, and Shadow Stars. The white letters painted on their foreheads that are found in the beginning of the names of the Air Ride Machines shows which Air Ride Machines they ride on.
