Godzilla: King of the Monsters director Michael Dougherty would love to introduce two more Toho monsters to the franchise if he were to return for Godzilla 3. Dougherty has expressed an interest in both Biollante and Gigan, who have both served as villains in previous films. The Godzilla series is packed full with various kaiju that the MonsterVerse can pull from as the franchise goes forward.
Directed by Gareth Edwards, 2014's Godzilla rebooted the classic Toho series and became the second American-made Godzilla movie. The film revived Godzilla's heroic image while pitting him against two other giant monsters called M.U.T.O.s. Godzilla was the only Toho property featured in the movie, but the sequel, King of the Monsters, will bring back three fan-favorite kaiju from the Toho films. Legendary acquired the rights to King Ghidorah, Rodan, and Mothra, making it possible for all three to get in on the action in the upcoming movie.
In an interview with Japanese website CinemaTodayJapan, Dougherty says he would love to use Toho monsters Biollante and Gigan in a future installment, if he were to return to the series. Dougherty also lists Anguirus and MechaGodzilla as some of his favorite Godzilla monsters.
Gigan is a frequent foe of the alpha predator and an occasional ally of King Ghidorah. Instead of hands, Gigan has hook-like blades which he uses to stab and slice his enemies. Gigan teamed up with King Ghidorah for a two-on-two showdown with Godzilla and Anguirus in his first movie, Godzilla vs. Gigan in 1972. Alongside Megalon, Gigan battled Godzilla and Jet Jaguar in 1973's Godzilla vs. Megalon. Gigan's third and final film appearance came in Godzilla: Final Wars in 2004, where Gigan received a powerful, cyborg-like update.
Unlike Gigan, Biollante only appeared in one film, 1989's Godzilla vs. Biollante. In the movie, Biollante was a genetically-engineered monster created from the DNA of a human, a rose, and Godzilla. The plant-like monster is among the largest kaiju ever encountered by Godzilla.
Both monsters are visually unique and could pose a significant challenge to Godzilla. The two could translate well into the MonsterVerse, if Godzilla 3 were to happen. Though no official announcement has been made, a third film does seem likely based on the success of Godzilla. If King of the Monsters and Godzilla vs. Kong are box office hits for the MonsterVerse, Godzilla 3 could be right around the corner.
