Now here's info about Gaira's trivia:
 * According to dialogue in Godzilla Against Mechagodzilla and books published for Godzilla: Tokyo S.O.S., Gaira and Sanda's appearance and battle in The War of the Gargantuas are part of that continuity of the Godzilla series.
 * Gaira's roars were later combined with Godzilla's roars and elephant sound to create the roars for the Ultraman kaiju Red King and Gomora.
 * During the long hiatus between Terror of Mechagodzilla and The Return of Godzilla, Toho and UPA considered making a film in which the Godzilla fought a Gargantua. This may have been one of the concepts they considered after Toho announced a new Godzilla film in 1978, under the vague title US-Japan Collaboration: Godzilla. Whether this would have been Sanda, Gaira, or a new monster is unknown. At some point, UPA owner Henry G. Saperstein also planned to produce a sequel to The War of the Gargantuas where Godzilla would battle a cyborg version of one of the monsters.
 * Like his brother, Gaira is absent from the cave painting on Infant Island showing ancient monsters aligned with the four elements in Godzilla: Rulers of Earth.
 * The Gaira suit used in the 2008 Go! Godman film was constructed from scratch by Fuyuki Shinada in a mere 4 days.
 * The first draft of Destroy All Monsters included Gaira as a resident of Monsterland. According to Nakajima the Green Gargantua was suppose to have a scene where he chases some soldiers before he was cut from the film and was replaced by Godzilla.
