UFO Kirby is a rare copy ability in the Kirby series. It was introduced in Kirby's Adventure. Kirby pilots a small flying saucer with his head being where his head is.
UFO Kirby is a powerful ability with unlimited levitation and wide array of moves that changes based on how long the player is holding the button. The play can still while charging but the direction they face is stuck until they let go. UFO Kirby cannot go down floors too, even with ladders. Until Squeak Squad, the ability would disappear when the player finished a level.
The UFO ability is also very rare. The UFO enemy is very rare and the copy essence for it is usually kept in the secret HAL rooms. In Kirby: Planet Robobot, the player can get at any time by tapping the Kirby series Kirby amiibo.
In Kirby's Dream Course, UFO Kirby is a short term transformation that allows the player to move freely in the air for a few seconds.
