He is the alternate reality version of Zachariah.
In the Apocalypse World, Zachariah served under the command of the archangel Michael during the Apocalypse against Lucifer and his demons. After winning the war against the demons, Zachariah and the other angels waged a war of extermination against humanity.
In late 2017, after the Nephilim Jack landed in the Apocalypse World on a rescue mission for Mary Winchester, Zachariah saw that he possessed the ability to open a portal between the two worlds for the angels to lead an army through. To that end, Zachariah convinced Michael to allow him to mess with Jack's mind in an effort to trick Jack into helping him. When his efforts continued to fail, Zachariah took on the form of Castiel within Jack's mind to communicate with him directly to try to turn Jack against Sam and Dean Winchester and to willingly help them. However, Jack saw through Zachariah's deception and Michael decided to take a more direct path.
Following the escape of Jack and Mary Winchester, Michael sent Zachariah to get Jack back and kill Mary while warning him not to fail again. After Jack used his powers, Zachariah detected it and led a group of angels to attack Bobby Singer's colony. As the other angels spread out to attack the humans, Zachariah searched for Jack and found Mary helping a little girl. Zachariah disarmed Mary, flung her to the ground and demanded "the half-breed."
As Mary faced off with Zachariah defiantly, Jack arrived and ordered Zachariah to stop. As Zachariah advanced on Jack, Jack lifted him into the air, screaming, with telekinesis. With a clench of his fist, Jack exploded Zachariah into dust, killing him. Jack then dispatched three more attacking angels, saving the human colony.
