Destronium

Destronium is a substance in the Transformers Animated continuity family.

Destronium is a substance that is incredibly volatile, risking detonation within a matter of minutes...and an essential substance for building Decepticons.

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.
