Barbatos (DC)

Barbatos is a major villain in the DC Universe and the Master of the Dark Knights he serves as the Main Antagonist of the Dark Nights: Metal event.

History
When Batman shot Darkseid with a radion bullet at the end of  Final Crisis, the dark god retaliated by striking Bruce down with his Omega Beams, seemingly killing him. Earth's heroes mourned the loss of one of their finest, but in reality, Darkseid had not killed Batman. He had used his powers to warp time around Bruce, infusing him with Omega energy and sending him back to the Stone Age without any memory of who he really was.

The infusion of Omega energy would cause Bruce to uncontrollably jump forward in time until he reached the present. Each jump would increase the concentration of Omega energy in Bruce's body, until his final arrival in the present, at which point the energy would blow a hole in time and decimate the universe. Once this happened, the Hyper-Adapter would take control of Batman's body, carving out a space in his mind for Darkseid to return, take possession of it and rule over reality once and for all.

In 1765, a young Thomas Wayne (Simon Hurt), along with numerous other influential colonial Americans, participate in a demonic mass where they attempt to summon the demon Barbatos, in an attempt to gain eternal life. When the summoning seemingly works, all of the men but Thomas flee in fear, locking Thomas underground with the demon. While Thomas believes he had summoned Barbatos, what actually appeared to him was Darkseid's weapon, the Hyper Adapter, which adapted to Hurt, with the intent of using Thomas as a weapon against his future descendant. Barbatos realised the similarities between his and Bruce's Bat emblems and believed he could use him as a doorway. Barbatos' followers manipulated events in order for Bruce to be injected with four out of the five metals needed to create the doorway, and after the fifth was injected in the present day, Barbatos was able to transport himself and the Dark Knights to Prime Earth to conquer it.
