In Rebirth of Mothra, the ReoFairy's name comes from another kaiju's name, Mothra Leo (モスラレオ?), and Fairy, which comes from Fairy Mothra's name.
In Rebirth of Mothra II, the KaiteiFairy's name comes from the film's Japanese title, specifically the word kaitei (海底?), meaning undersea, and Fairy, which comes from Fairy Mothra's name.
The ReoFairy's design is very different than the ShodaiFairy's, no longer bearing a striking resemblance to the HeiseiMosuImago, although still having a similar wing pattern. The ReoFairy's body is more light yellow than the ShodaiFairy, and its face and eyes are different, with the eyes now being cyan and smaller and the antennae being longer and thicker, as well as its 'whiskers' being a different shape. Like the other Fairy puppets, it has a black underside, and like it successor, it has legs with black joints. This puppet is also known as the KaiteiFairy (海底フェアリー?, KaiteiYōsei) in Rebirth of Mothra II.
