Dark Energon corrupts energon. If it could get access to the ring, it game over. But I think it would take a little bit to get over the side effects if it didnt get the ring.

There's one flaw here. The only one's who use Energon as a power source are the Transformers. It wouldn't do anything to a Green Lantern ring, or any other super-technology that doesn't work on Energon.
