Mammon is a minor antagonist in Final Fantasy: The 4 Heroes of Light.
Before the events of the game, Mammon arrived in the Sun Temple and caused a great snowstorm to spread cold throughout the region. The everlasting cold caused residents of Invidia to become cold and heartless, and only Rekoteh seem to be unaffected by it. After Rolan was corrupted by Lucifer, Mammon continued to use her snowstorm, rendering Invidia to its current condition during the game's present timeline.
After being sent fifteen years into the past, the party goes to Invidia and meets up with a younger Rekoteh. After the party obtains the Dragon's Mark in the Invidia Underground, Rekoteh explains to the party that Mammon caused Invidia to be the frozen town it is now. The party travels to the Sun Temple and fight Mammon, defeating her and lifting the curse on Invidia. Later, Mammon is revived within the Star Chamber, but she is defeated once more.

Like the other major demons in the game, Mammon refers to one of the seven princes of Hell in demonology, each one representing one of the seven deadly sins. Mammon is a concept as old as the Bible having to do with greed, avarice, and materialism in the Old Testament. In the New Testament, the concept is personified as a false god. Mammon is latter referred to in various literary works, including the Divine Comedy, as the demon that personifies the avarice, one of the seven deadly sins.
