Lucifer

Lucifer is a fallen angel and the Devil in Christian theology. Lucifer is associated with the sin of pride and believed to have attempted an usurpation of God, whereafter being banished to hell.

The concept of a fallen angel attempting to overthrow the highest deity parallels Attar's attempt to overthrow Ba'al in Canaanite mythology, and thrown into the underworld as a result of his failure. The story is alluded to in the Isaiah and transferred to Christian beliefs and is also used in the Vulgate (the late-4th-century Latin translation of the Bible).

As the antagonist of God in Christian beliefs, some sects of Satanism began to venerate Lucifer as a bringer of freedom and other religious communities, such as the Gnostics and Freemasons, have been accused of worshipping Lucifer as their deity.

Lucifer is still a frequently reoccuring figure in popular media. Provided by Wikipedia
