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 a 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
