Fortress Maximus (Animated)

The central base of the Cybertron Elite Guard, Fortress Maximus boasts significant amounts of firepower dedicated to the defense of Cybertron. Naturally, this requires a fair amount of energon to be diverted to it if it's to bring its full arsenal to bear.

The Fortress was constructed during the reign of the awkwardly-named Powered Convoy Magnus.

As acting Magnus, Sentinel Prime ordered that all available strategic energon reserves be directed to Fortress Maximus, to bring its main gun online and target Omega Supreme. Luckily for Omega (and Cybertron), it missed when Omega transwarped away at the last second.

''Kremzeek attempted to turn the Fortress Maximus's main guns on Iacon, much to the consternation of Jetfire and Jetstorm. Sentinel seemed more concerned with how Sari and Arcee had managed to get into the base. Fortunately for all involved (except Kremzeek), Sari's quick thinking captured the imp before it could cause any real harm.''
