Earth Defense Force

The Earth Defense Force (地球防衛軍 Chikyū Bōeigun), or abbreviated to EDF, is a military organization created to protect humanity from Titan threats. In order to defend cities from other Titans, the EDF was created to analyze and study Titan behavior, powers and history. They have special weaponry in order to fend off Titans from populated cities.

Name
The Japanese name of this organization, Chikyū Bōeigun, literally translates to "Earth Defense Force." Its name is also abbreviated as EDF.

History
Anywhere between the 1960s and 1970s, the EDF was created to fend off attacks from enemy Titans. One of the Titans they successfully fended off was Manda, in 1989, using Maser Submarines. They created other weapons like the Oxygen Destroyer (whom they created a new Titan, designated Destoroyah), Maser Cannons and Maser Planes. They also settled their main headquarters in Tokyo.

Episode One - The Arrival
In Tokyo, the EDF were analyzing two Titans, one of them being Zilla and the other being her son. When a facilitator asked how the son grew up so fast, a UFO was detected that it had entered the atmosphere. The UFO housed the Xiliens, aliens that came from another planet to warn Earth about their future. The Xiliens said that a monster, designated Monster Zero, was about to destroy Earth and that they must evacuate the Earth for their survival.

One day, Godzilla arrived at Shizuoka and attacked the city. The EDF wondered how their satellites didn't detect an attack and why their satellites' responses were delayed.

The EDF sent their Maser Planes and Cannons to fire cadmium missiles to wear Godzilla down. However, Godzilla was unaffected and kept on rampaging across the city. The next plan was to blast Godzilla with Maser beams. While a Hyper Maser Cannon damaged him greatly, the King of the Monsters unleashed an Electromagnetic Pulse, disabling the vehicles' weaponry and shields. While attempting to escape, Godzilla destroyed the Hyper Tank and blasted a plane to the ground. Just then, Anguirus came to confront Godzilla, and eventually fought him, with the EDF providing Anguirus extra support. However, Godzilla was scared off by an Xilien UFO ray and retreated to the sea.

The Xiliens said that Earth could no longer be safe with Godzilla rampaging and Monster Zero about to be unleashed to the Earth. As preparations to leave Earth began, two scientists had a vision, at which they arrived at Infant Island and met Mothra's priestesses, the Shobijin. The Shobijin told the scientists that the Xiliens are servants of evil and that Ghidorah is a pawn of their plan. 12,000 years ago, the Xiliens sent Ghidorah to attacking earth, with Dagon and Rozan managing to seal him off in the ice, and that the Godzilla who attacked them was an impostor and that the real Godzilla was trapped inside the Xilien UFO. On top of the Shobijin's prophesy, the radiation levels for Shizuoka were zero, meaning that it was a Fake Godzilla who destroyed the city. The Xiliens' plans failed to trick the humans.

In response, the EDF sent Maser Planed to attack their UFO. Both had their shields on, so they couldn't hurt each other well, until Rodan came to rescue the real Godzilla. By performing the Asteroid Dash and leaking off the Tranquilizer Gas, Godzilla woke up and proceeded to break his binds and chains. When the Xiliens dropped Godzilla through a portal, Rodan rescued Godzilla, with the EDF watching by, seeing if the story of Monster Zero was real or not.
