Decepticon Detention Center

The Decepticon Detention Center is a prison run by the Decepticons on Cybertron. Among its detainees are the renegade Decepticons, political prisoners who had been reduced to mere personality components and filed away in a drawer in Cell 217.

The Transformers cartoon
When Starscream was booted out of the Decepticon base for trying to overthrow Megatron (again), the once and future Air Commander traveled to Cybertron and infiltrated the Detention Center, seeking the renegade Decepticons. He knew to look for Cell 217, and once inside, he quickly found his quarry in a wall of drawers. Taking the personality components, he fired several explosive shots at the remaining drawers, apparently destroying them and their contents. Starscream is a bit of a dick.

When Shockwave discovered that the personality components had been stolen, he informed Megatron, who concluded that Optimus Prime and the Autobots were responsible. Megatron assaulted the Autobot base, demanding the return of the renegade Decepticons. Optimus Prime's confusion did nothing to halt Megatron's attack; only a fusion cannon failure forced his retreat. Megatron is also a bit of a dick.

When Prime asked Teletraan I about "renegade Decepticons," the computer not only knew their history, but also somehow knew that they had been taken from the Detention Center the previous day.

After taking control of the Decepticon army, Megatron announced that the Combaticons and anyone else who refused to recognize him as ruler would be sent to the Detention Center.
