Lucifer is a minor antagonist in Final Fantasy: The 4 Heroes of Light.
Prior to the events of the game, Rolan was sent from Spelvia to stop Chaos and his minions. When Chaos heard of this, he sent Lucifer to stop him. Lucifer, seeing that Rolan had doubt and sorrow within his soul, manages to corrupt Rolan by placing Geri and Freki within him. This caused Rolan to hate all humanity during the game's present timeline, until he was defeated by Brandt and the others.
After being sent fifteen years into the past, the party returns to Spelvia and goes back into Rolan's Soul. While inside, they meet up with Rolan and help him defeat the demons within his soul. At the final level of the dungeon, they discover that Lucifer was corrupting Rolan and caused his darkness to expand. The party defeats Lucifer and return Rolan to his normal self. Later, Lucifer is revived within the Star Chamber, but he is defeated once more.
Lucifer is fought twice in the game, once in the Rolan's Soul and another time in the Star Chamber.
Non-Final Fantasy guest appearances
In Bravely Second: End Layer, Lucifer appears as an optional boss fought west of Eternia as part of the Seven Sins sidequest and represents the sin of Pride. It gives access the Yōkai to the Diabolism spells Pride and Aeroja.
Like the other major demons in the game, Lucifer references one of the seven princes of Hell in demonology, each one representing one of the seven deadly sins. Lucifer is the demon of pride, which is befitting since he is the demon fought in Spelvia, a city named after the Latin word for the sin of pride, superbia.
Lucifer is a Latin word (from lucem ferre), literally meaning "light-bearer". In English, "Lucifer" generally refers to the Devil, although the name is not applied to him in the New Testament. The use of the name "Lucifer" in reference to a fallen angel stems from an interpretation of Isaiah 14:3–20, a passage that speaks of a particular Babylonian King titled Morning Star (another name for the planet Venus) as fallen or destined to fall from the heavens. In 2 Peter 1:19 and elsewhere, the same Latin word lucifer is used to refer to the Morning Star, with no relation to the Devil. In post-New Testament times lucifer has often been used as a name for the Devil, both in religious writing and in fiction, especially when referring to him before he fell from Heaven. Lucifer is also one of the Seven Princes of Hell, representing the Sin of Pride, often seen as the worst of the Seven Deadly Sins.
