A normal U.F.O. is a small, apparently mechanical Nobody with a thin, spike-shaped main body. Its head is spherical and is adorned with a white Nobody sigil. Its body is mint green and pale purple. A gold ring lined by four long, mint green spikes surrounds the U.F.O.'s main body. There are also Red and Gold versions of this Nobody Ship.
The U.F.O.'s name is a reference to Unidentified flying object—typically abbreviated to "UFO". The U.F.O. resembles a flying saucer, a stereotypical UFO. "Ring Type" seems to simply refer to the Nobody's central ring.
It fires shots from the spikes on its ring to attack the Gummi Ship. The Red and Gold versions drop treasures when defeated.
