The eldest of the brothers and hence is the leader of the household, Lucifer presents himself as a calm, composed, and intimidating person. His brothers frequently comment on how scary Lucifer can be. He is a very strict and unforgiving demon and does not hesitate when doling out punishments to his younger brothers.

As the Avatar of Pride, he displays a great sense of pride.
Lucifer has sworn allegiance to Diavolo, the future king of Devildom and his closest friend. The demon brothers, especially Satan and Belphegor, often accuse Lucifer of only caring about Diavolo and maintaining his good image and reputation.

Lucifer also tends to show excessive concern for his brothers, thus proving that he cares about them. His excessive care is often perceived as stifling and controlling rather than comforting.

He is very fond of theater.
After watching a good play, he is likely to ramble on and quote his favorite parts, even if the person he is talking to does not share his enthusiasm.
He has stated that his "type" is someone who is "pure, sincere, and worthy of respect," although he was actually describing a soul, not a person.
Lucifer prefers his tea stronger.

Lucifer declares that he is not a morning demon. Lucifer doesn't like technopop (synthpop).
He calls it "cacophonous beep-blop music".

Lucifer and his brothers used to be angels who lived in the Celestial Realm. Lucifer was a high-ranking angel who was also known as The Morning Star, unequaled in beauty and respected by everyone.

An incident regarding his youngest sister Lilith, who broke a rule from the Celestial Realm by giving food from their world to a human she fell in love with, led their Father to make the decision to have her obliterated. This made Lucifer brutally angry, and his attempts to stop this eventually made him lead a revolution against God, with various other angels and his siblings on his side. This conflict would become known as the Great Celestial War, in which Lucifer and his siblings lost and were banished from the Celestial Realm and landed in the Devildom.
As an angel, he used to speak quite harshly, bordering on rude in some instances, but was still very direct and honest about his feelings. Now as a demon, the events that led to his current existence soured his relationship with his past home; his greatest fear is dying and ascending back to the Celestial Realm.
