Destronium

Destronium is a substance in the Transformers Animated continuity family.

Destronium is an essential substance for building Decepticons. The genuine material's properties are unknown, save that it allows the creation of substances sturdier than normal Earthly ones for building servos and such. However, its Earth-made synthetic equivalent is incredibly unstable. Moving it at high speed makes it incredibly volatile, risking detonation within a matter of minutes.

Trivia

• Destronium is most likely derived from Destron, the Japanese name for the Decepticons. Considering that the Japanese name for the Autobots is Cybertron, it may even be a counterpart of sorts to Cybertonium, a slightly differently spelled substance from the Generation 1 cartoon which was critical for the proper functioning of Transformer bodies.
