The Galactic Conspiracy is an alliance of planetary governments, who all bear a grudge against the Hero Factory.
The Hero Factory has made frequent enemies of corrupt governments through their activities, and a number of powerful planetary governments eventually banded together in order to get rid of the Hero Factory.
Part of the conspiracy involved creating a weapon to utilize against the Factory, which was codenamed Project Sunstorm. The conspiracy hired two scientists, Dumacc (who was unaware of the nature of his employers) and Karter to oversee the project. The weapon was hidden under layers of deceit, described as a defense mechanism but constructed in secret using the development of the Valiant as a disguise. Testing of the weapon eventually caused a massive environmental disaster on Tranquis VII. The Brains, during their own attempts to reach and destroy the Hero Factory, uncovered Project Sunstorm and tried to activate it. The Hero Factory was able to defeat the Brains, but Karter destroyed the project, revealing his nature as a villain, and was imprisoned in the Factory.
After being placed in the Hero Factory jail, Karter was visited by an old associate, Perjast, who was secretly bearing a powerful hologram device that would allow Karter to destroy the Hero Factory from within. The conspiracy disabled Perjast remotely, allowing Karter to take the device and use it to tamper with an energy test the Factory was conducting. The tamper was successful, apparently killing several members of the Alpha 1 Team and allowing Karter to escape. However, an alarm was eventually sounded, signaling the destruction of the area surrounding the Factory. In touch with his employers in the conspiracy, Karter pleaded to be rescued. The alarm turned out to be a ruse, and Alpha 1 leader Preston Stormer (who had not been killed in the blast) took over Karter's communications, and issued a direct threat to the conspiracy. In response, the conspiracy leader killed Karter remotely by overloading his circuits.
The Galactic Conspiracy is comprised of a number of planetary governments, each with their own reasons for despising the Hero Factory. Together, they possess an enormous amount of resources, enough to be able to purchase or develop powerful technologies, including illegal ones, that they use in their plot. They also have a vast network of spies, with some situated in neighboring planets to Makuhero Planet, in order to keep a close eye on the Hero Factory.
