Lucifer (Supernatural)

Lucifer, also known as Satan or the Devil, is the main antagonist of the TV series Supernatural.

He is a fallen angel, (the first fallen angel) and one of four Archangels. When God told him to bow before humans, Lucifer refused, and he started a Rebellion, corupting many Angels to his side, he was however defeated, and cast out of Heaven, in hatred of humans he corrupted a human soul into the first demon, and for this he was cast into a Cage the angels had made specially for him by his brother Michael.

When the leader of the demons, Azazel, made a sacrifice to talk to Lucifer, he told him to break Lilith out of Hell so she could break the 66 Seals and release him. The final Seal was broken when Sam Winchester, Lucifer's intended vessel, killed Lilith, and Lucifer rose out of Hell and was free on Earth.

As an angel, he needed to take a vessel on Earth, and could only possess someone with his or her consent. He possessed a man named Nick, whose family had been murdered by a criminal, and persuaded Nick he could get revenge on God for allowing his family to be killed; and tried to convince Sam to say yes to him, as he was his true vessel. Sam, Dean, and Castiel planned to defeat him by either finding the Colt or finding God. However, when Dean shot Lucifer in the head with the Colt, it did not kill him, as he was one of five beings the Colt could not kill. Sam and Dean also heard from the angel Joshua that God had no interest in stopping the Apocalypse.

His brother Gabriel, formerly known as the Trickster, tried to kill him with a trick after he killed a vast number of gods, but Lucifer turned his own angel-killing blade on him and killed him. However, Gabriel revealed to Sam and Dean that they could trap him by reopening his cage with the Four Horsemen's rings. Sam and Dean collected the rings, and formulated a plan to get Lucifer back into the cage. Sam said yes to Lucifer intending to gain control over him and jump back into the Cage with Lucifer, but Lucifer easily overpowered Sam and turned him into a dark path by allowing Sam to kill the demons who had controlled his teenage life.

As Lucifer and Michael were about to fight, Dean and Bobby arrived in an attempt to make Sam regain control. When Castiel threw a molotov of Holy Fire at Michael to temporarily send him away, Lucifer said "No one dicks with Michael but me" and destroyed Castiel by snapping his fingers. When Bobby shot him, Lucifer snapped Bobby's neck. He beat up Dean, but when he saw a figurine of a soldier in the Impala, Lucifer was overwhelmed and confused by all of Sam's memories with Dean. Sam was able to regain control of his body and open Lucifer's Cage with the Rings of the Horsemen of the Apocalypse. Michael appeared and told Sam that he was destined to kill Lucifer, and Sam refused. So Michael grabbed hold of Sam just as he jumped into the Cage, and took Lucifer and Michael down to Hell with him.

God resurrected Castiel, who resurrected Bobby and freed Sam from Lucifer's Cage. Lucifer still remains in the Cage; Castiel discovered he had freed only Sam's body, but Sam's soul was being beaten for all eternity by Michael and Lucifer; who were furious with him. Dean got Death to rescue Sam's soul, and Death warned Sam there would be evil memories if Sam tried to break the wall Death had constructed round his soul. However this wall begins to break and Sam hallucinates him, as a side effect, of him remembering all the torture he put him through. Lucifer's hallucination continues to torture Sam, thus leading to Sam nearly dying in a car collision. Sam puts himself into a mental hospital. Lucifer continues to psychologically torture Sam inside the hospital by appearing as his doctor. However, when Sam is at his worst, Castiel returns and absorbs Sam's torturous memories, healing Sam, yet temporarily going insane as Castiel sees Lucifer. However, being an angel and being stronger than Sam, Castiel manages to get the hallucination of Lucifer under control. Lucifer's hallucination is banished and Lucifer is still trapped inside his Cage with Michael.
