Before humans, before gods, before life, and even before the Creation of the DC Multiverse, Yahweh, the Almighty, created two brothers, Samael and Michael. Yahweh then bestow each of them gifts: to Samael, he was given the gift of fire and will and to Michael, that of creation, and the demiurgic power.
Major Story Arcs
During the course of Ostrander's the Spectre series, Michael plays a recurring role as the direct voice and agent of Heaven when dealing directly with the Spectre, often standing in the Spectre's path when it or Jim Corrigan would demand an audience with God or entry into Heaven.
In the past it was revealed that the fallen angel that would become the Spectre, was faced with Michael when it came to repent it's actions and that it was he who reformed it into the Spectre to serve as the Wrath of God before setting it to usurp Eclipso the Revenge of God.
Many hundreds of years later, the Lamb was born, and it was decreed that all greater spirits like the Spectre must walk on the Earth clothed in humanity, it was Michael who had to beat the Spectre into submission as the wild spirit was little more than rage. At the battle's conclusion, Michael disguised himself as a Hindu deity before bonding the Spectre with a human, creating the first modern Spectre. Likewise, it was he who bonded the Spectre to Jim Corrigan when he was given the mantle.
During Corrigan's tenure as the Spectre, he used Michael and the heavenly laws against an ancient spirit called Azmodeus, a creation of Lord Belial, who was the first Spectre host now blind with hate over how his wife was reincarnated as a diseased beggar that was stoned to death by villagers. Appealing to the man inside, Corrigan managed to separate the man from the spirit and let Michael damn it back to Belial's realm, marking one of the few cases where the Spectre and Michaeal cooperated without coming to blows.
When Lucifer rebelled in heaven billions of years ago, Michael led God's forces against Lucifer but during the battle he was felled by Sandalphon from behind when he hesitated. From that point on, he was kept in captivity by "Lucifer's follower" whose grand scheme was to use Michael's genetic material to create an army of archangels to finish what Lucifer started, which basically is to overthrow Heaven.
The majority of these children were failures but one, his prize, was not, for even better than having the Demiurge inside the child, the child was a female, meaning she could sexually create even more servants for him, she was of course Elaine Belloc. But before Sandalphon could put these plans to fruition, Lucifer came to collect both Elaine and Michael from Sandalphon for he himself needed them. It was revealed that if Michael should die, the release of the power within him would destroy creation.
Lucifer brought Michael to The Lux and was eventually granted entrance for it was the only place it would be safe for Michael to die and rebirth, and there it was that Lucifer impaled his brother and the Demiurge filled the Void.
After dying, Michael was reborn, healthy and full of life once again and he and his brother parted ways. Michael returns to Heaven where he seeks out Yahweh's counseling... counseling which he did not expect . Michael is exiled from Heaven and he begins a quest to find and rescue his daughter.
The Wolf Beneath the Tree
After he fled Destiny's table in a rage, Michael flew straight to Heaven and landed upon the ledge The Logos, the place where God's voice lives, and once within Michael went to sleep, and poured out the Dunamis Demiurgos into all things, renewing Yahweh's name on every atom in creation moment by moment.
Lucifer interrupts and incinerates The Logoz. Emerging from the rubble a clearly enraged Michael gathers himself rather quickly and says, "Speak quickly, Lucifer. Or I call this Host to witness -- you will not speak again."
Lucifer wins Michael over, and they head to Svartalfheim. Michael is confused as to why they need to be in Svartalfheim if their journey to Yggdrasil won't be physical. Lucifer responds by telling him that The World Tree expects to be approached from such a direction which in relativity, should make things at least a little easier for the three of them. Michael, Lucifer, and Elaine all plummet to the base of the tree,with Michael and Lucifer now unconscious and Elaine blind.
In the fields of Yggdrasil, Michael awakes. Swiftly he clambers to his feet and rushes to get between the two, trying to push Elaine away from his brother, warning Lucifer to stay away from Elaine. But Lucifer's only reply is, "Morningstar? I am Fenris. I am The Wolf!" With that, Lucifer and Michael now begin their final fight, with Michael trying his best not to harm his brother. Michael tells Lucifer to fight it, to be himself, lest all their pain and effort be for naught and creation falls. But Lucifer simply turns his head to the side, blood dripping from his mouth as he grins evilly at his brother, "Excellent." Than in a blur of speed he grabs his brother and Lucifer takes to the air, glowing with energy as he takes his brother higher into the heavens. As they ascend Michael still pleads with his brother, "Morningstar -- brother -- I don't want to kill you --" but Lucifer simply scoffs at these words as he points out that with his broken wings, Michael's strength is failing. His own rant thus begins, "I am the furnace in which you will be unmade. I am your death." But Michael remains stubborn and responds by telling Lucifer that he will be the death of all, and that it will all be his own doing and his alone. Lucifer heeds not these words in his madness and a massive expulsion of power erupts from within him, engulfing both sons of Yahweh, leaving them both to plummet to the ground, burning as they fall.
Michael and Lucifer crash through the upper branches of Yggdrasil, snapping them as they continue their descent, lost to view for some time, but than after things seem to calm down with the departing of Fenris, a broken Lucifer stumbles over to the place where his brother lays in a pool of blood, at the base of the tree, his own leathery wings are naught but spines now, jutting from his back. Cleared of mind he weakly speaks his brother's name, but it is too late. Michael is dying, the fate of creation sealed, but the latter issue is not the current problem for Michael's death provides a problem in and of itself. And so he calls out to Elaine, asking her to come to him, the blinded Elaine follows the voice of her father until she is kneeling at his side. Within himself he holds a power, Yahweh's power, the Dunamis Demiurgos, and should he die, this power would be released, overwhelming all of creation and erasing it. Than it is that her father utters his last words, proving that he can acknowledge his own faults "It would have done no good. I was proud, and stubborn. I could have sought you out. I could have --" and so he dies, Elaine hovering him, a scream ripped from his throat as his nigh-uncontainable energy bursts forth from his body, engulfing Yggdrasil and all within its perimeter.

Michael Demiurgos is the 2nd most powerful being, rivaled only by his twin brother Lucifer, and surpassed by their father, God of the Covenant and all of Creation. Michael was given the Demiurgic power of God, with this power; He spawn the cosmos out of the nothingess and alongside his brother created the DC Universe.
Although it was Michael, which brought the Creation from the Nothingess, It was Lucifer who shape it all.
