Mammon is currently the archenemy of Spawn and is portrayed as one of the hellspawn's most powerful enemies to date: surpassing even his former master Malebolgia, however for all his power Mammon is still inferior to the true lord of Hell in Spawn's universe: Satan - the cosmic "twin" of God and another of Spawn's many enemies.
Mammon has always shown himself to be a master of manipulation and doesn't like to get his own hands dirty unless he has to, in direct contrast to Violator's tendency to get violently involved in bloodshed (often for fun).
Mammon is a very powerful creature who bargains with humans for their souls and rarely finds a soul that can resist his charm, he is believed to have masterminded most of the events that led to Al Simmons becoming Spawn - Mammon's current goal is to attain the Throne of Creation so he can weld the power to remake the universe in his own image.
Mammon's power is shown by the fact that Malebolgia - a demon long believed to be Satan - was "but a flea" in comparison to Mammon: his status in Hell is shown by the fact high-ranking demons refer to him as "Lord" but refer to the true Satan as "Master" (meaning Mammon is apparently second in command next to the King of Darkness).
Mammon appeared as a minor, but important character in the videogame Spawn: Armageddon.
- Mammon's name is derived from that of the mythological being who is both an ancient fertility god and an embodiment of excess wealth, in theological writings the name "Mammon" is attributed to a humanoid and demonic representation of the sin of avarice.
