Michael

Michael is the eldest archangel, which makes him the oldest angel in creation. He was made Viceroy of Heaven in God's absence, and is one of the most powerful beings in the universe. He commanded the Heavenly Host (God's Army of Angels) before he fell with Lucifer in The Cage. As the highest-ranking archangel, he issued the commands, which went to the higher ranking angels to disperse the orders down across the angelic chain. During the War In Heaven in the distant past, Michael banished Lucifer from Heaven on God's command, later restricting him to a Cage bound by The 66 Seals.

On Earth, he appears using John Winchester as a vessel to Dean. There, Michael informs him that anyone in the Winchester bloodline is capable of being his vessel, even though he mentions that Dean Winchester is his one true vessel. He eventually occupies Adam's body while confronting Lucifer, who was using Sam as a vessel. When he falls into the Cage, Heaven loses stability and is currently hosting a conflict between Raphael and Castiel, amongst other angels.

Personality
Michael sees himself as a good and loyal son to his father, and that matters most to him. He professes love for Lucifer, his younger brother, but insists that he is only serving his father by destroying his brother. He seems to think himself magnanimous when he promises to leave Dean whole, not catatonic, after serving as a vessel.

Powers and Abilities

 * Immortality: Michael, being the first ever angel, cannot be killed, no matter what. He is isn't affected by time, diseases, nor does he need to breathe, eat, or sleep to sustain himself.
 * Angelic Possession: Michael, like all celestial beings, requires a human vessel in order to physically interact with humans on Earth, as it is a law that applies for all angelic beings.
 * Invulnerability: Michael is resistant to nearly all forms of harm, as there aren't any methods of injuring, or killing him, to date. Lucifer, however, can at least injure him. Death's Scythe could probably kill him.
 * Super strength: Michael, like all angels, dramatically increases the physical strength threshold of his host.
 * Overpowering: Michael can easily overpower other angels, deities (other than God himself), humans, creatures, and possibly Lucifer, with his might.
 * Healing Factor: When Michael's vessel does get damaged by something angelic, he can heal the wound(s) instantly.
 * Teleportation: Michael, like all celestial beings, can vanish and reappear anywhere in time, space, and any place on the face of the Earth.
 * Telekinesis: Michael can move people and or objects just by thinking.
 * Pyrokinesis: Michael can ignite any object or thing by physical touch.
 * Resurrection: Michael, like all archangels, can easily revive dead people.
 * Memory Manipulation: Michael can remove or restore memories of humans.
 * Holy White Light: Micheal like other archangels can obliterate buildings and beings completely.
 * Superhuman Intelligence: Michael's understanding is extensive, even greater than Lucifer's.

His insistence that his actions only serve God is not entirely true, because blames Lucifer for the loss of their father, and is angry with him. He also becomes furious with anyone who interferes with his destiny, including his Dean at Stull Cemetery, and again with Lucifer, when he suggests that they refuse to fight. It is this stubborn insistence on fulfilling his story as written that leads him into imprisonment in the Cage.

Weaknesses
Holy Fire can temporarily banish Michael. An Archangel Killing Blade can kill Michael. Other Archangels may be able to harm Michael. If he has the weaknesses of other angels, he can also be confined by a circle of holy oil, and kept out by Enochian sigils. Lucifer, and possibly other Archangels can kill him. Death's Scythe or Death himself may be capable of killing him as well.

Early Life
God created Michael, the first archangel, the eldest of four brothers, Lucifer, Raphael, and Gabriel. After the creation of Heaven, its angels, and Earth and its people, God commanded all of the celestial beings to bow before mankind, asking them to love humans more than himself. Lucifer questioned this order, insisting that they are "flawed, murderous beings." Lucifer then sought out his older brother, Michael, for support, but Michael refused to listen. At some point, God left Heaven. Michael assumed command of the angels, and then ran Heaven and Earth for millenia.

When demons began making plans to free Lucifer, Michael decided to allow the seals binding Lucifer to be broken. He and a group of other angels, including Raphael and Zachariah, wanted the Apocalypse to occur so that he and Lucifer could battle. Michael expected to be victorious, so as to bring about paradise. Lesser angels, like Castiel, were not privy to the plan, and were deployed to make it look as though Heaven is fighting the devil's release.

Season 2
In "Houses of the Holy", Sam notices a painting of Michael by killing Lucifer by the renaissance painter Raphael in the Church they visit.

Season 4
In "Lucifer Rising", while Zachariah is informing Dean of his true purpose he is looking at an illustration of Michael in a painting in the Green Room.

Season 5
In "Sympathy for the Devil", upon Lucifer's rising from the Cage, Zachariah reveals to Dean that the angels' plan is for Michael to use Dean Winchester as his vessel and kill Lucifer once and for all. However, Dean needs to give his consent to be the vessel.

In "The Song Remains the Same", Michael first manifests when Sam, Dean and Castiel have traveled back to 1978 to stop Anna Milton from killing John and Mary in order to prevent Sam’s birth, and thus his use as Lucifer’s Vessel.

After Anna Milton injures Mary and kills Sam Winchester by stabbing him in the stomach, Michael converses with John Winchester from Heaven, and tells him that he can save his wife Mary if he allows him to take possession of his body. John says "Yes," allowing Michael to inhabit his body.

When Anna is about to kill Mary, Michael calls out to Anna. Anna turns around and immediately realizes that Michael is possessing John. Michael lays his hand on Anna and kills her by setting her ablaze. Uriel then calls out to Michael and apologizes, saying that "He didn't know," most likely referring to that he didn't know Dean was Michael's true vessel. Michael says goodbye to Uriel and sends him away with a snap of his fingers.



Michael then turns to Dean and says that this conversation is long overdue. Dean demands that Michael heal Sam, but Michael tells him that they need to talk first. Dean asks Michael how he could possess his father since he was his "one and only" vessel. Michael corrects Dean stating that he is his true vessel and that he can inhabit the body of all those that share the Winchester bloodline due to the fact that he and John were descendants of Cain and Abel.

He then explains to Dean that even though Lucifer defied their Father and betrayed him, he doesn't want to kill him as much as Dean wouldn't want to kill Sam. Michael then says regardless of the fact that he raised Lucifer and still loved him, he is going to listen to his Father and kill Lucifer. He then explains to Dean that he will eventually say "Yes" to him because free will is an illusion and that his choices, regardless of what they may be, will lead him a step closer to his destiny that was planned out by God.

Michael tells a saddened Dean to cheer up because, unlike his brothers, he won't leave him a drooling mess after he's done "wearing him". He then tells Dean that he will erase John and Mary's memories of the whole incident and that they won't remember anything about angels, him, or Sam. Michael walks over to Sam's body, heals him, and then sends him back to his own time. Michael then walks to Dean, telling him that he'll see him soon before sending him back to his own time.

In "Point of No Return", Zachariah has been dismissed from his position and is drinking in a bar, awaiting his destruction, when Michael makes contact. The brilliance and sound of the unshielded archangel kills the bar patrons and Michael offers Zachariah a last chance to secure Dean as a vessel.

Meanwhile, seeing no other way to defeat Lucifer and save the planet, Dean is prepared to consent to becoming Michael's vessel when it is discovered that his half brother Adam Milligan has been resurrected. The angels hold Adam as bait, and Sam and Dean attempt to rescue him.

{C Zachariah tortures Sam and Adam in front of Dean, and Dean tells Zachariah he will consent. Zachariah utters an incantation that summons Michael to their location, only for Dean to kill a distracted Zachariah with an Angel Knife. Sam and Dean manage to escape before Michael descends, but Adam is trapped inside the room and vanishes with Michael. Adam is technically a vessel, if only a temporary one, for Michael, being of the Winchester bloodline.



In "Swan Song", Michael's appears at Stull Cemetery in Lawrence, Kansas in possession of Adam's body in order to face Lucifer in the final battle of Armageddon. Lucifer tries to convince Michael that they shouldn't fight because God made Lucifer the way he is, because he always wanted the Devil. Michael isn't convinced and the two prepare to fight just as Dean drives down into the cemetery and interrupts them.

{C As Dean tries to talk to Sam, Castiel and Bobby appear and Castiel hits Michael with a holy oil molotov cocktail in order to send him away temporarily. After Lucifer makes Castiel explode and breaks Bobby's neck, he begins to beat Dean. This continues until Sam reclaims control of his body and opens the portal to Hell.

Michael returns and tells Sam that he can't jump in because he has to fulfill his destiny by killing Lucifer. Sam then pulls Michael with him as he falls into the portal, trapping Adam, Lucifer and Michael in Hell.

Season 6
Subsequently, in Heaven, Raphael informs Castiel that he wants to release Lucifer and Michael so that the Apocalypse can be re-started. While talking with Dean, Castiel speculates that Lucifer and Michael are probably abusing Sam's soul, as they see their imprisonment as his fault. Balthazar makes a similar assumption. Dean explains to Death, who already knows, that Michael, still inside Adam Milligan, also fell into the cage, and requests that the Horseman retrieves both Sam's soul and Adam's body. But Death forces him to pick one - Dean picks Sam.

Season 7
In "Meet the New Boss", Castiel tells Crowley he's keeping Hell as a place for his enemies, and to keep Michael and Lucifer in the cage. Why this is remains unknown, but most likely even with all the souls Castiel had at the time Michael and Lucifer could still have laid him to waste.
