An energon cube is a device used by characters in the fictional Transformers series to store energy.[1]

Animated series

In the 1984 animated Transformers television series energon cubes are created by the Autobots and Decepticons on Earth.[2] The Autobots trade with the humans for the power, while the Decepticons steal the power.[3] For all practical purposes, energon functions as fuel or "food" for the Transformers; in some episodes, Decepticons are depicted as literally drinking from Energon cubes.

In "Transformers: Energon" the Autobots and Decepticons have made an alliance with the humans, with one of their missions to find energon. The fuel source is revealed to be mined on Earth, Mars, and the Moon. A special group of Transformers, the Omnicons, consisting of Autobots and Decepticons, use the energon to be made safe for Autobots to use. A plot in the TV series is that Alpha Q sends his Terrorcons to steal energon to repower Unicron.

In "Transformers: Prime" the Autobots and the Decepticons are in a race to retrieve energon from Earth. Energon is used as a power source and as ammunition. Energon is also revealed to be unsafe for humans. Energon itself is made from the essence of Primus. A darker version of it, Dark Energon, known as the Blood of Unicron, is also known to exist. Megatron is the only major user of Dark Energon. The power can bring dead Cybertronians back to life in a zombie-like state, or it can strengthen a Transformers. It is revealed at the end of season one that Earth's mantle is really made of Dark Energon.


Energon cubes are used in the 1985 book and audio story Megatron's Fight For Power by John Grant as well as the 1986 Find Your Fate Junior book Autobot Alert! by Judith Bauer Stamper.[4]
