Energon

Energon is the main substance and valued resource used by all Cybertronians for food, medicine and for their own biology. It is the blood flowing inside and throughout their bodies. It is from the blood of their creator, Primus. It can be found in energon deposits sent from Cybertron or inside Cybertronians. Energon deposits are on Earth, but little are easily minable. It can be harmful to humans if made contact. Though if humans are infected by Dark Energon, then Energon can aid them, only with a professional Cybertronian scientist to help with the procedure.

Cybertronians require energon in order to live their lives anywhere they go. Energon can be converted into ammunition and energy for energon-dependent weapons and equipment. Cybertronians refine Energon for fuel in their health and technology. Once energon is refined, it's formed into a liquid state and it can be placed into containment units.

In battle, energon is spilled from poor victims. Once energon is spilled from Cybertronians, it cannot be reused.

Cybertronians rely on this matter to survive. This pure substance played a role in the conflict between Autobots and Decepticons in order to gain control over it.

Energon doesn't have an exact taste and it is unknown if Cybertronians can actually drink Energon (though Predacons were revealed to be able to do so in the covenant of Primus). Autobots and Decepticons inject themselves with Energon to fuel up usually.
