Alternium

Alternium is a material in the Alternity portion of the Generation 1 continuity family.

Alternium is a material that resonates with higher dimensions. Its crystalline lattice structure is capable of storing memories and even entire life-forces of sentient beings. Only a fraction of its true immensity is visible to lower-dimensional beings, appearing to be a simple metal. Discovered by the Timaeus Project, it played a role in the origin the manifold beings known as the Alternity, due to the fusion of the substance with Cybertronian life. It is the primary substance making up the bodies of the Alternity as well as that of the great beast Hytherion. When fashioned into a hyper-frame, it allows the Alternity to control an auto-avatar, and thus interact with lower dimensions.
