Transformers Energon

Energon Cube

Energon is the primary fuel source for all of Cybertron’s inhabitants. The power source exists in a raw form throughout the planet, although it has become far less plentiful throughout the course of the war Energon has also been found to exist in its raw form in varying quantities on other worlds, including the third planet in the Sol system. The unusually high quotient of Energon on this world was brought to Optimus Prime’s attention by the Council of Ancients, leading the Autobot leader to seek it out in the Ark.
