He was an alternate universe version of Lucifer.
During the Apocalypse, Lucifer was described as having been "torn apart" in the skies over Abilene by Michael. His death led to Michael becoming the victor of their world.
When Michael discovered another Lucifer who had crossed over from another reality, he informed Lucifer of his counterpart's fate and intended to treat this Lucifer the same way. He easily overpowered him in combat.
While talking with Mary Winchester, Bobby Singer stated that when Lucifer and his demons rose from Hell, the human race believed that the angels were there to save them. However, the angels ended up turning on the human race one by one.
While talking with Sam Winchester, Charlie Bradbury reveals that when Michael and Lucifer began their war, an EMP or something like it went off over North America, frying all technology on the continent.
When Lucifer and Michael fought, they thought God would return and give them answers, why he left, why they'd done, but he didn't return instead.
