Chronos

Chronos is the greek god of time. He goes under the alias Ethan Snider.

Background
Before when he was worshiped he used to suck the life from human sacrifices. No longer worshiped Chronos was forced to feed after a couple decades on three humans to stop wandering time. He eventually met a human woman, Lila Taylor and fell in love with her. Although he didn't tell Lila who he truly who, but was forced to kill in order to return to her. His powers sent him into the future so he needed power to return.

On his last feeding in 2012, he is tackled by Dean, and Chronos takes both of them back to 1944. He intended to get rid of Dean but found that Dean was let go by Eliot Ness. So when he notices that Eliot is lurking about he attacks, but doesn't finish Eliot off due to a moment of distraction. Later Dean breaks in and the two fight, but are stopped when Eliot takes the Lila hostage. Chronos begins to choke Dean, but is summoned back to 2012 where he faces Sam. He lets go of Dean and fights Sam. Chronos is stabbed in the heart by the stake and as hes dying gives them his final premonition by telling them their world is full of black goo everywhere. He soon passes.
