Protectobots' Headquarters

The Protectobots' headquarters serves as the base of operations for the Protectobots. It is located in an unknown city and disguised as an inconspicuous apartment building with a billboard advertising for E Cola on top. The streetside wall can open to let the Protectobots in or out. To keep in touch with Autobot Headquarters safely, the Protectobots' headquarters houses equipment that is uniquely capable of receiving messages on a sub-frequency range.
