Fuyuu appear out of thin air and fly around using propellers. These small, slow-moving reaverbots do not have much impact on their opponents, but they always appear in groups, making them more troublesome.

The purple type are commonly found throughout the Nakkai ruins, but a second variety also exists, the Yellow Fuyuu. This second type appears in groups of four around the head of the Colossus and are essentially indestructable; Destroying one will merely result in the materialization of another.
