Dark Energon is one of the most evil forms of dark magic in Cybertronian History. It is said to be the blood of Unicron himself, the destroyer of world. It is used to bring dead Transformers back to life; however, it makes them a mindless creature upon rebirth. However, those with strong minds like Megatron are able to use it for power. It is also extremely poisonous to humans. Raf Esquivel was a victim of Dark Energon, but Ratchet and June Darby were able to save him by giving him Energon.
