History

Shattered Glass

In March of 2012, Alpha Trion successfully tracked the Old One to his hidden lab, where the evil sage was waiting. Backed by his henchman Blitzkrieg, the Old One attacked Alpha Trion with his Terminus Blade, critically injuring him before being driven back by Dust Devil and Firestar. After the Old One's face was shattered by Dust Devil's Ebon Dagger, the Old One retreated with Blitzkrieg's aid, leaving the Terminus Blade behind. Dust Devil retrieved the Terminus Blade while rescuing Alpha Trion, and gave it to him to study while he recovered from the Old One’s attack. Alpha Trion suspects that the Terminus Blade is a weaponized counterpart to the Key to Vector Sigma.

However, while Alpha Trion had the Terminus Blade in his possession, he found himself influenced by the Blade's power, becoming increasingly arrogant and maniacal. Crafting a protective sheathe for the blade, he gave it back to Dust Devil for safe-keeping.

Alpha Trion and Dust Devil later used to blade to draw out the Old One, but he escaped before they could capture them. The Terminus Blade is currently being held in the Temple of Knowledge, although the Autobots fear that soon the Old One will return for it.

Ultra Magnus discovered that the Terminus Blade was being held in the Temple of Knowledge, and hatched a plan to destroy Cybertron. After sending a warning to Jetfire to tell Optimus that Cybertron was about to be destroyed, Magnus teleported into the temple with the use of one of Wheeljack's Stellar spanners.

Magnus attempted to kill Alpha Trion, but Trailbreaker defended Trion from the attack with one of his forcefields. Tracks was dispatched to stop Blaster, and was able to drive Blaster back and burn out one of his optics. Wreck-Gar focused on acquiring the Terminus Blade from Dust Devil, and brought back several Autobots from the dead to use as his minions. Wreck-Gar and his Junkions, however, were kept at bay by Firestar's fire.

Magnus attempted to use a doomsday device to destroy Cybertron, but before Wheeljack was able to complete the device Dust Devil preemptively activated it with the Terminus Blade. Magnus attempted to escape with the Terminus Blade before the doomsday device detonated, but Trailbreaker tossed it through the Wheeljack's portal before it closed. It is unknown if Magnus and his troops survived the detonation.
