Decepticon Headquarters (Armada)

Decepticon Headquarters, also known as Megatron's Fortress Headquarters, is the secret base used by the Decepticons directly under Megatron's command for roughly one million years. It is located in Cybertron's eastern peninsula. Motion blasters make up the bulk of security, which are effective, but certainly not failproof.

Decepticon Headquarters doubles as a prison complex for Mini-Cons, whom the Decepticons systematically hunt for to use their abilities for their own purposes. To make that possible, the prison area is linked to a set of laboratories, the so-called chop shops, where the Mini-Cons are subjected to experimentation and forced reassembly.

Of all the Mini-Cons the Decepticons had abducted from their homes, only the members of the Air Defense Team had been able to escape Decepticon Headquarters, who spread word about the atrocities happening there among the remaining Mini-Con community. The warning was heeded, but in all came too late for the Mini-Cons to properly prepare for the speed and cunning with which the Decepticons executed their attacks. By sheer luck, Sparkplug evaded capture and was taken in by the Air Defense Team. They had a plan to save the others and Sparkplug agreed to help them accomplish it.

When the four arrived at Decepticon Headquarters, Sparkplug was intimidated by the building's defenses, but the Air Defense Team assured him the motion blasters were the only problem. On Sparkplug's subsequent question how they'd get past those then, they presented him with a makeshift jet pack. As Sparkplug was flown all over the place, distracting the motion blasters, the Air Defense Team went inside and freed the captured Mini-Cons. At this point, the building's security system sent out a signal to the Decepticons in Cyber City, but it was already to late for them—or anyone else—to stop the Mini-Cons from escaping Cybertron and all its bulks.

Even with most Mini-Cons out of their reach, the Decepticon continued their battle to conquer Cybertron, their ranks swelling in numbers over the course of many years. It is unknown if Decepticon Headquarters stayed in use, was destroyed, relocated or perhaps even upgraded into Decepticon Command Headquarters. Whatever the case, one million years after the Mini-Cons had fled Cybertron, Megatron's base of operations picked up a Mini-Con signal from the planet known as Earth. He and his soldiers immediately programmed their headquarters' space bridge to bring them to Earth and because the Mini-Con hunt proved a little more troublesome than initially expected, the Decepticons set up a temporary base in Silver Ridge. They never returned to their old headquarters.
