U.F.O.

A U.F.O. is a type of Gummi Nobody that can be found on various Gummi Missions in Kingdom Hearts II. It is distinguished by the rotating spiked ring around its midsection. It fires shots from the spikes on its ring to attack the Gummi Ship. There are also Red and Gold versions of this Nobody Ship that drop treasures when defeated.

Design
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.

The U.F.O.'s name is a reference to —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.
