For different types of energon, please see here.
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.
Male and Female 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.
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.
For liquified energon see here:
Breakdown's energon wasn't seen to be spilled on screen as MECH dissected him.
When Starscream scrapped Arcee on her side, Arcee leaks her energon on the ground. As she battles Starscream, Arcee holds her wounded side to stop her energon from coming out. Arcee's wound was healed by Ratchet but she was still holding on to her side.
Ratchet injects Synthetic Energon into himself and slowly starts to change. When Megatron punched Ratchet on the side, Ratchet leaked the synthetic energon on the ground. After Ratchet was rescued by the Autobots, Knock Out discovered a small drop on the broken container that he filled with the leaked energon.
Optimus punched Megatron so many times that Megatron leaked Dark Energon from his mouth. After Optimus was knocked to the ground by Megatron, Dark Energon began to come out of the volcano that was behind them.
Airachnid leaked a lot of Energon when Breakdown and Dreadwing hunted her down. Starscream leaked energon from his side after being attacked by Airachnid's insecticon. Megatron leaked energon when fighting the insecticon.
Red Energon was discovered by the Autobots and Starscream and tried to get it.
Starscream used the remaining Red Energon to steal the Omega Keys from the Autobots.
Insecticons were sent to save an Energon mine, but they were tricked by the Autobots.
Knock Out used Dark Energon, under Starscream's order, to infect Silas. This ended in a disaster and Silas started to drain the Energon out of several Vehicons turning them into Terrorcon craving monsters.
Team Prime went to uncover an Energon mine despite their reserves at a critical low. They succeed in bringing back some Energon to the base.
Ratchet was captured and decided to help the Decepticons in making his unfinished synthetic Energon experiment for the new Omega Lock. The formula was completed when Ratchet tried to escape the ship and was used to power the Omega Lock.
When Megatron shot Bumblebee, his body fell in the Omega Lock's Cybermatter. When Bumblebee was resurrected by the Cybermatter, he killed Megatron with the Star Saber, which Megatron was bleeding from his chest where he was impaled. Dark Energon was stained on the sword when Megatron's lifeless husk fell to Earth.
Unicron used his Dark Energon to revive Megatron and used his body as a vessel. In Shockwave's hidden lab, Skylynx and Darksteel knocked over some Energon cubes. Optimus trapped Unicron's dark energon spirit in the AllSpark's container.
- Regular Energon could be considered like regular Earth water. The types of Energon may apply to water related or containing products, such as Synthetic Energon with energy drinks to cybertronians.
