Movie Name: Godzilla vs Mothra vs Mechagodzilla: Tokyo S.O.S.
 

To be released December, 2003

Plot Summary (special thanks to Monster Zero News):

Mechagodzilla, having lost its arm and damaged its Absolute Zero cannon during its previous battle with Godzilla, is docked and being repaired. While this is happening, the doctor who originally discovered Mothra (1961 version) and his nephew are on vacation near Infant Island when the twin Mothra fairies suddenly appear to give an important warning. Using Godzilla's bones in the construction of Mechagodzilla, they explain, was a huge mistake. If the Japanese government continues to use Mechagodzilla, Mothra may refuse to help fight against Godzilla the next time he attacks. In fact, Mothra may even become an enemy to mankind instead of a protector. Godzilla's bones must be returned to the sea, the fairies continue, or dire consequences will befall Japan.

But is Godzilla still alive? Did he survive his battle with Mechagodzilla and his experience with the Absolute Zero cannon? Well, the discovery of a dead giant tortoise indicates that he is indeed alive (the main cause of death is thought to be a deep scar on the neck received from a mightier giant creature, most likely Godzilla). And so, the doctor and his nephew bring the twin fairies to the Japanese Prime Minister so that he can hear their warning for himself. Of course, nobody believes them.

And then, the inevitable occurs: Godzilla shows up in Tokyo again. The Self-defense force leads Godzilla into Shingawa in the hopes that he can be ambused by MechaGodzilla. But suddenly, Mothra shows up and a great battle ensues. Meanwhile, Mechagodzilla is finally ready to join the battle. But who will fight against whom?
