The Deathbringers is a race of winged humanoid aliens who idolize an entity know as the "Lord Beyond the Void" that resides behind a rift in space. In the distant past, in the name of this being they they went through the galaxy, slaughtering millions on Earth, Rann, Thanagar, Krypton, and many others worlds. The Deathbringers would sacrifice the few survivors on their temple world of Qgga because each death made his god be able to enter the universe.

However, while preparing the final sacrifice that would allow their Lord to enter the universe, Ktar, the Deathbringers' general felt guilty of all the death his people had brouth to the worlds and turned on the Deathbringers, destroying Qgga and sending the Deathbringers into the void, at the cost of his life.

But the Deathbringers managed to return to the universe with two tasks: first, complete the final sacrifice and bring their god into the universe; and second, get revenge on Ktar who was still alive alive, trapped in an endless reincarnation cycle as the superhero Hawkman.
