Lucifer

History
God created the Archangels namely: Michael, Lucifer, Raphael and Gabriel. After all of the Archangels were created they formed a strong and a very meaningful bound with one another. But after the creation and start of mankind, Lucifer began to argue constantly with his brothers and with God. At first, these arguments annoyed Gabriel but he eventually became upset and was angered by these arguments which directly resulted in his voluntary exile. God then commanded his Angels to bow before Man, but Lucifer refused and was cast out of Heaven. As an act of defiance, Lucifer twisted a human being's soul to create the first demon, Lilith. He was then confined against his will to a Cage by Michael. The Cage could only open if the 66 attachments on the Cage broke. Sometime after Lucifer's incarceration and the creation of humans as he rotted and grew weak in his Cage, humans started referring to Lucifer as Satan and the Devil. In 1972, Azazel possessed a priest at St. Mary's Convent and killed eight nuns in the chapel. This enabled him to speak to the imprisoned Lucifer. Lucifer tells Azazel that Lilith is needed to break The 66 Seals that hold him captive in the Cage and that he needs to find a very special child. Lucifer is freed when The 66 Seals that were attached to the mouth of the Lucifer's Cage all break - the final seal being broken inadvertently broken by Sam when he kills Lilith. While on Earth, Lucifer with the help of the Four Horsemen of the Apocalypse, causes chaos and natural disasters and plots to cause the destruction of humanity and to kill Michael. Essential to Lucifer's plan is the possession of his destined vessel - Sam Winchester. Sam and Dean try to kill Lucifer with the Colt, but fail. Sam comes up with a plan in which he will allow Lucifer to posses him, and then force him into the Cage. The initial attempt fails, but when Lucifer confronts Michael at Stull Cemetery, Dean activates the rings and as the cage opens, Sam manages to gain enough control to force himself (and Lucifer) into the Cage. Michael (in possession of Adam) tries to stop him but is himself also captured.

Raphael is working to open the Cage, so that Michael can finally kill Lucifer. In 6.06 You Can't Handle The Truth, Dean tells Bobby that he thinks Sam is still possessed by Lucifer upon his release from the The Cage because of his new cold and relentless behavior towards everything. He also shares this with Castiel who quickly dissuaded the comment, say that if Lucifer had escaped the Cage, his presence would have been felt by all humans. In 6.10 Caged Heat, Castiel tells Dean that Sam's soul has been locked in Lucifer's Cage with Michael and Lucifer for over a year, and that the two Archangels are more than likely abusing Sam's soul. He tells Dean that is against returning Sam' soul.

Powers and Abilities
Immortality: Lucifer, like all celestial beings, is not subjected to time, aging, or diseases, and doesn't need to breathe, eat, or sleep to sustain himself. Lucifer does, however, like all celestial beings because they're all siblings of one another, age and mature, as he is the second oldest angel.

Angeilc Possession: Lucifer, 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: Lucifer, like all archangels, is resistent to any form of harm whatsoever, and can't even be harmed by other beings, unless something angelic is invovled, or if he is fighting another archangel.

Super Strength: Lucifer, like all angels, dramatically increases the strength threashold of his host.


 * Overpowering: Lucifer can easily overpower other angels, deities (other than God himself), humans, creatures, with his might.

Healing Factor: When Lucifer's vessel does get damaged by something angelic, he can heal the wound(s) instantly. Lucifer, at first, while occupying Nick, was acceptable to damage by Colt bullets yet he could not be killed by the gun; the bullet mark disappeared almost instantly though. Later while conjoined with his true vessel, Sam Winchester, the colt gun had no effect on him whatsoever.

Teleportaion: Lucifer, like all celestial beings, can vanish and reappear anywhere in time, space, and any place on the face of the Earth.
