In the wake of Godzilla's first appearance in 1954, the nations of the world formed the Earth Defense Force to combat him and the many other monsters that appeared around the globe over the following decades. The Earth Defense Force had succeeded in its purpose, and the entire globe was safe once again from the Mysterians.
The surviving UFOs eventually retreated to the Mysterian Space Station, ending their invasion campaign at last. The remaining Mysterian UFOs fled the dome as it exploded, some of them being shot down by the Alpha and Beta as they fled. After Ryoichi Shiraishi severely damaged the Mysterian Dome from the inside, the Mysterian Leader ordered his forces to retreat. The Mysterians deployed a second Moguera to destroy the Markalite Cannons, but it burrowed to close to one and it collapsed on top of it. The Markalite Cannons successfully damaged the Mysterians' dome, while the Alpha and Beta were able to bring down several of their UFOs. The EDF constructed a second Beta and modified the Alpha to withstand the Mysterians' death rays, then deployed them along with several Markalite Cannons for a final confrontation with the Mysterians.
The EDF's scientists worked to develop a new weapon that would be effective against the Mysterians' defenses: the Markalite Cannon. The two ships were sent to assault the Mysterian Dome, but its powerful death rays completely destroyed the Beta and forced the Alpha to retreat. The first results of this collaboration were two VTOL aircraft called the Alpha and Beta. The nations of Earth held a summit and agreed to combine all of their military forces and scientific ingenuity to form the Earth Defense Force. History Showa era The Mysterians Īfter the Mysterians obliterated the JSDF's units using their dome and UFOs, Japan appealed to the other nations of the world to band together to fight their common enemy. In Godzilla: Unleashed, the organization is called the Global Defense Force, or GDF for short. In The Mysterians, its name is rendered on a sign in English as Defence Force of the Earth. In these media, its name is also abbreviated as EDF. The Japanese name of this organization, Chikyū Bōeigun, literally translates to "Earth Defense Force," however this English name is only used for it in Godzilla Final Wars and in video games.
