The Earth Defense Command is a joint effort between Earth and the Autobots to coordinate and streamline communications for emergency response from external threats to the planet regardless of their source. It was initiated in 2012 by discussions between Spike Witwicky as Autobot liaison and General Hawk of GI Joe, and expanded with the help of Blaster, Crosscut, Dial-Tone, and Marissa Faireborn.
In the wake of massive global disasters perpetrated by the Decepticons, Spike and General Hawk felt there was a need for a closer tie between Earth military powers and the Autobots in order to counter these threats. To that end the Earth Defense Command, or EDC, was formed. Its original purpose was to permit a means to contact the Autobots quickly in the event of attack since the Autobots could not be in all places at once. However, human militaries could provide assistance until the Autobots could arrive to help combat the problem via coordination with the EDC. An emergency communications channel was set up for this purpose, and Spike was named the human liaison.
In March 2013, the need for EDC unexpectedly arose with the imprisonment of human rights activist (and GI Joe and Autobot sympathizer) Anwar Assan. Though a joint mission was about six months too early for some members of EDC, the need for both the Joes and the Autobots to rescue Assan while maintaining plausible deniability required the skills of both factions to ensure neither were ensnared in any international backlash regarding such a mission.
In April of that year, the EDC executed their mission almost flawlessly, rescuing Assan and his wife with no Autobot or G.I. Joe casualties and very few witnesses.
In 2018 the EDC was reorganized as a division of the Autobots, and Marissa Faireborn was promoted to field commander. As the years progressed since its founding, the EDC became more of world-wide defense effort as more militaries joined the cause via the UN. Today the Earth operations of the EDC work directly with the UN Security Council in matters pertaining to global defense. Although the Decepticons have not been seen on Earth in several years the damage that they wrought remains firmly in Earth's collective memory and it will not be permitted to happen ever again.

In the Decepticon World, the EDC was briefly set up as a resistance force against the Decepticons when they proceeded to invade Earth and take over its inhabitants. The organization was made up of members of both G.I. Joe and Cobra. However, the Decepticons quickly decimated most all of EDC's resources in a series of dramatically once-sided battles. Early on in EDC's formation, the leaders were captured and publicly executed in front of a worldwide audience by the Decepticons.
Since then, EDC has gone underground. Pursuing funding through any measures, including that of billionaire G.B. Blackrock, EDC now operates as a much more scaled back resistance movement, now dubbed ERC for Earth Resistance Command. Employing guerrilla tactics against the Decepticons, the members of ERC, fight desperately for any perceived victory they can against their Decepticon conquerors.
