Omega Key

The Omega Key is an object from the Aligned continuity family.

Amusingly enough, not the key to the Omega Lock.

The Omega Key is an important relic in Cybertronian culture that dated before the onset of the Great War. Typically, it is held by the Prime and leader of the Autobots who guarded it from abuse as it held the power to guide users to the very core of Cybertron itself. However, what was not known was the fact that the Key itself did not open the Omega Gate but simply alerted its Guardian who was the only Transformer capable of opening the doorway into the Core.

War for Cybertron

During the closing years of the Great War, the Decepticons staged a daring raid against an orbital space station above their homeworld that was rumored to contain a powerful as well as dangerous energy source known as Dark Energon. After Megatron gained control of the facility and his new Sky Commander Starscream activated the Geosynchronous Energon Bridge, Dark Energon began flowing into the Decepticons ranks. Seeking to gain complete control over Cybertron, Megatron sought access to the Core of the planet itself. However, he needed the Omega Key to open the Omega Gate. Unfortunately, the Key was in the hands of the Autobots—notably their leader Zeta Prime. Thus, the Decepticons laid siege to Iacon itself where Megatron successfully defeated Zeta Prime and took the Key from him...which immediately started to blink. It was only then that a laughing Zeta Prime revealed that the Key's activation only awakened its Guardian, Omega Supreme who was coming to attack Megatron.

Since the Key would lead them to Omega Supreme, the three Decepticons boarded a dropship to search Iacon, only to be attacked by Omega Supreme. Having finally discovered the true key to the Omega Gate, Megatron discarded the Omega Key as no longer useful. War for Cybertron
