Mammon

True to his title of 'Avatar of Greed', Mammon is naturally greedy and always seeking out opportunities to profit without putting much work. The first thing Mammom does every morning is check his stocks. Although he's the second eldest, he acts immaturely when he doesn't get his way and is the biggest troublemaker of the brothers. He's egotistic and prideful, though it seems that it is only a façade to cover up his soft nature. Mammon is also quick to lie, but not very good at it; in many stories and chats, he stutters when he denies something (even while texting). He has a tendency to shout whenever he's angry or upset (which is most of the time) as well as growl when he's irritated. He often praises himself when he thinks any of the brothers compliments him (even if they aren't) and thrives on being complimented. He acts impulsively and often speaks before he thinks. It's because of this that Lucifer takes great precautions and enforces multiple rules that inevitably inconvenience the rest of the brothers. Mammon is sensitive to change and highly empathetic.
