Checker Knights is an Air Ride course in Kirby Air Ride. It is often considered the most difficult Air Ride course in the game. The secondary music track that plays here is the theme of Green Greens, and the original track, which was actually taken from the anime, later appeared as a song in Super Smash Bros. Brawl.
Checker Knights is a surreal area located somewhere in Dream Land. The course mainly takes place on a checkerboard with somewhat medieval-styled castles and walls, among more unusual structures like half-pipes. About one third of the way through the track, the racecourse plunges underwater, revealing a dark undersea cityscape illuminated by neon lights, with floating rails, pipes and cubes above. The racers then return to the surface for the final third. The course incorporates almost every enemy in the game (even outside of Free Run), and has many challenging twists and turns, along with unique elements like Spin Panels. A one-of-a-kind pink switch panel near the end of the course, when activated, temporarily raises an obstacle inside of a small room directly ahead. This panel is most likely intended to be activated as a surprise means of shaking off competitors following closely behind the player, as long as they are able to avoid it themselves.
Checker Knights is one of the most difficult Air Ride courses in Kirby Air Ride. Its setting is a surreal and abstract blend between the medieval and the futuristic with checkerboard patterns. The Checker Knights soundtrack actually originates from the anime, Kirby: Right Back at Ya!, titled Strong Star Warrior. The classic Green Greens is the unlockable alternate track.
