8. Nekron

The embodiment of Death, Nekron takes his power from those who have passed away. His state alone is terrifying enough. He created the black power rings to reanimate the dead in a new evil form. He is also responsible for transforming Superman, Wonder Woman or Green Arrow into Black Lanterns.
He is the most powerful dark force in the DC Universe and his limitations are unknown. He has no soul and that makes him immune in front of the Spectre, he kills Guardians with a touch and Life Entity is a force that he is able to fight against.
He is very resistant and he can manipulate reality; he sent Anti-Monitor back into the anti-matter universe, didn’t he?
This darkest and extremely powerful force will always shake the universe when he’s attacking.
