Greed is an evil spirit and the embodiment of greed. He is one of the seven Corrupted Elemental spirits, and was one of the few on the loose, alongside Lust and Envy, as Tomix took care of the others. In Mogloween 2009, he made the Cauldron Sisters argue and split up in order to create their own candies by corrupting them with greed. After that he spread his Greedlings to Falconreach, making its residents not want to share their candy and causing them to fight for it. Most notably, he made the peaceful Patch, nice old Grams, cute Twilly and alchemist Reens fight against the hero because they didn't want to share their candy with him or with the rest of Falconreach. He is the archenemy of Tomix the Soulweaver. By making everyone share their candy again and convincing the Cauldron Sisters to combine their candies and make the perfect candy, Tomix and the hero were able to stop the greedlings, but Greed had gained much power from the greed of the citizens. Even though the duo was able to defeat him, he ran to the underground city of Ravenloss.
Outside of Mogloween, Greed passed through the Gate of Enlightenment and wanted to obtain the Wheel of Judgment in order to become human and by doing so become immortal and corrupt all of Lore with greed and selfishness. His wish of becoming human succeeded but he was defeated by the Hero, and ultimately, killed by Vaal himself.
Greed is one of the seven evil souls (a parody of the Seven Deadly Sins) released when Tomix did the thing he regretted.
