David Graves was a historian and published author, interested in fringe history. He wrote a series of books, on subjects such as
Atlantis, the miracles of Fatima, the
Nazca lines, and how they could affect the modern world. Shortly after the
Justice League was established, Graves, his wife Jennifer, and their two children Jason and Emma are attacked by
Darkseid's forces, but are saved by the Justice League. Believing that the superheroes were a modern incarnation of the gods of antiquity, Graves set out to research a book about the heroes. It became his most popular title, "Justice League: Gods Among Men". Within a year of the formation of the Justice League, Graves developed an unspecified malady which left him using a wheelchair and unlikely to last another year. Faced with the knowledge that his family was gone and the heroes were not going to save him, Graves snaps, shoots his doctor, and vanished. Four years later, Graves returns completely unrecognizable from his former self, with the faces of his children on his arm. Vowing to destroy the Justice League for their hubris, Graves breaks into the Black Room, a secret facility where
A.R.G.U.S. stores mystical items. Graves determines that the best way to destroy the Justice League would be through their public liaison
Steve Trevor. Graves interrogates
Key,
Weapons Master,
Scarecrow,
Cheetah,
Captain Cold and
Scavenger to discover the weaknesses of each Justice League member. He then kidnaps Steve Trevor and tortures him, threatening to kill his family. ==Powers and abilities==
