Mothra vs. Bagan (モスラVSバガン,   Mosura tai Bagan) is an unmade 1990 Mothra film.


Mothra vs. Bagan would have been Mothra's first non-stock footage appearance since Destroy All Monsters and would have introduced the monster Bagan, who had previously been conceptualized for Resurrection of Godzilla. The film would have been set in the same continuity as the Heisei Godzilla series, and as such was to include the character of Miki Saegusa. The movie was to have a direct sequel in the form of the tentatively-titled Godzilla 3, which would have had Godzilla encounter Bagan. Due to the poor box office performance of Godzilla vs. Biollante and also the unlikely success of the film overseas, it was cancelled.

The first version of the movie reused the concept of Bagan being a shape-shifting monster with three forms from Resurrection of Godzilla. However, Koichi Kawakita axed the element, ultimately leaving Bagan with only a single form.


Thousands of years ago, a giant monster terrorized ancient China. The demon monster known as Bagan rose to destroy the world's forests and everything living in them. Although an ancient clan of Mothra were able to defeat the creature, legend passed down through the ages claimed that the "primordial dragon" would rise again. In the present day of 1990, the glacier containing Bagan melts from rising global temperatures, and the monster sets its sights on humanity. However, standing in Bagan's way is Mothra, a giant insect monster that acts as Earth's guardian. Mothra confronts Bagan at the Thailand-Malaysia border and momentarily manages to drive him away. The two monsters then meet again, this time in Bangkok, where Bagan surprise attacks Mothra from the skies as she is retrieving the Shobijin. Mothra is mortally wounded by Bagan's assault, and in a last-ditch effort, uses a poison powder attack to severely weaken Bagan, enough to allow her to carry him away from the city. Some distance away in Borneo, a gigantic egg is formed by the song of the Shobijin, and it soon hatches an infant Mothra, which crawls to help its mother. The three monsters then engage in one last battle for the sake of the world. Fortunately, with their combined strength, Mothra and her larva are able to best Bagan, and the adult carries Bagan's unconscious body out to sea where she seals him away again. As she dies, her body dances from the skies onto the surface of the water, where she drifts on spread, vivid wings.

  • Many elements from this film were carried over into Rebirth of Mothra in 1996:
    • Like Bagan, Desghidorah is an evil monster that destroys Earth's forests and was sealed away in ancient times, only to be reawakened in the present day by human activity. Desghidorah shares some physical similarities with Bagan, as they both grew wings just before the final battle.
    • Mothra's larval offspring hatches and joins her in battle against Desghidorah.
    • Mothra carries another monster out over the ocean, then dies. While in Mothra vs. Bagan she carried the unconscious Bagan out to sea, in Rebirth of Mothra she carries her larva to safety to escape Desghidorah.

I'll do you one better -- I've had in the works a full translation for the entire "Mothra vs. Bagan" draft script, which is where all these details for the plot come from. Here's a preview of the ending sequence!

SCENE 233 On the beach Bagan attemps to move his arms but cannot due to Mothra Larva's webbing, and chases after Mothra. Mothra retreats over the sea. Bagan enters the sea. Mothra Larva dives underwater. It spits thread towards the legs of Bagan while beneath the surface. The webbing tangles Bagan's feet. Bagan falls. Mothra Larva reemerges. It approaches the fallen Bagan. Mothra also approaches Bagan from the sky. The Mothra Larva spits more starch silk over Bagan's body. Mothra also attacks, using the last of her poison powder. Bagan, while suffering, has its face and horn wrapped in a white cocoon. With a loud roar, Bagan falls forward, becoming quiet and not moving. Bagan's wings which had previously been flapping have also stopped. SCENE 235 On the beach Mothra grips the still Bagan wrapped in the white cocoon with her feet, lifts it up slowly and flies out to sea. SCENE 237 Off the coast of Thailand: South China Sea The shining, sparkling sea surface off Chaoyang. A long silhouette appears - Mothra comes flying, carrying Bagan. Mothra releases Bagan. A large water column rises on the surface of the sea. As if to witness the last of Bagan, Mothra circles several times over the spot, and breathes her last.

Mothra falls to the water's surface as if dancing.

Do you have any evidence if the plot is right, SuperGodzillaGaming?
